Brief Introduction to Features of LED Driver

According to the electricity rules and the characteristics requirements of LED driving power, during the selection and design of LED drive power, an LED driver manufacturer suggested that customers should take into account the following several points:

1. High reliability: especially driver for LED Street lamps, installed in high altitude, with inconvenience of maintenance and large maintenance cost.

2. High efficiency LED is a kind of energy-saving products, which have high requirements on efficiency of the driver. For power supply installation, the structure of LED driver inside the lamp is particularly important. Because the LED luminous efficiency decrease with the increases of LED temperature, LED heat sink is very important. If the power is of high efficiency, its consume power is small, heat inside the lamp will be small, and the temperature rise will be reduced, which is benefit to delaying LED lumens depreciation.

3. High power factor: Power factor is requirement to load from grid. Generally there are no mandatory targets for home appliances of below 70 watts of power. Although single electrical equipment of low power has little impact on the grid, but at night when all lights are turned on, similar load is too concentrated, and it could have a more serious pollution on the grid. For LED drivers of 30 watts to 40 watts, it is said that in the near future there may be certain requirements on power factor.

4. Drive mode: generally there are two types: one is a constant voltage source offering for several constant flow sources. Each constant voltage source individually supplies power to each LED. In this way, the flexible combination, one LED failures will not affect the other LED's work, but the cost will be a little bit higher. Another one is direct constant current power supply with LED in series or in parallel. It has the advantage of low cost, but suffers bad flexibility, and also has to solve the problem that failure of a LED can not affect other running LED. Both of these two forms coexist in some time.

5. Surge protection: LED surge capacity is relatively poor, especially anti-reverse voltage capability. Enhancing this protection is also important. Some LED lights are installed outdoor, such as LED street lights. Due to the using of power grid load and lightning induction, there will be various surge invade from the grid system, and some surge will cause damage to LED. Thus, LED driver should be able to curb the surge intrusion and protect the LED from being damaged.

Classifications of SFP Optical Transceiver

Rate Classification
In accordance with the rate, there are 155M/622M/1.25G/2.125G/4.25G/8G/10G SFP optical transceivers, among which 155M and 1.25G are used widely on the market. 10G SFP technology is becoming mature, with rising trend development of demand.
Wavelength Classification
According to the wavelength, SFP optical transceiver can be divided into 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. The one with 850nm wavelength is SFP multi module, while SFP single module is of transmission distance below 2KM and the wavelength 1310/1550nm. In addition, it enjoys transmission distance more than 2KM. These three wavelengths are sold on relatively cheaper price than the other three.
Nude modules without identity are easy to be confused so that manufacturers will generally distinguish them on the color of the rings, such as: black ring for multimode, of wavelength 850nm; blue is module of wavelength 1310nm; yellow is module of 1550nm wavelength; purple is module of wavelength 1490nm.
Module Classification
Multimode
Almost all of the multimode fiber sizes are 50/125µm or 62.5/125µm, and their bandwidth (fibre information transmission quantity) usually are 200MHz to 2GHz. Through the multimode optical fibers, multimode optical transmitter and receiver can transmit for 5 km. SFP multimode module adopts light emitting diodes or lasers as the light source. Their ring color is black.

Single Module
Dimension of single module optical fiber is 9-10/125µm, and compared to multi module optical fiber, it has unlimited bandwidth and low loss. Single module optical transmitter and receiver are mostly used for long distance transmission, sometimes reaching 150 to 200 km. It adopts LD or LED of a narrow spectral line as light source. Its ring colors may be blue, yellow, or purple.
Differences and Relations
Single module fiber optic is cheap, but single module device cost much more than the same type multi module devices. Single module devices can usually run in both single module optical fiber, and multi module fiber, while multi module devices are restricted to running on the multimode optical fiber.
10G SFP optical module has been through development of 300Pin, XENPAK, X2, XFP, ultimately achieving to transmit 10G signals by the same size with SFP, and this is SFP+. SFP, by its virtue of small size and low cost, meets the high-density requirements of devices to optic modules. Since 2010, it has replaced XFP and become the main stream in 10G market.

Brief Introduction to Waterproof LED Strip

Definition
Waterproof LED strips are also called waterproof LED flexible strips. The product is shaped like a soft tape, with strong flexibility, collapsible and flexible, with LED SMD beads of uniform low power distribution on surface. Waterproof LED strips can give out brighter light as replacement for traditional lighting and so they are called LED flexible strips. According to customers' needs, they can give out light of a variety of colors such as red, green and blue, as well as light of colors matched by those three primary colors. Their colors are soft and bright and can be used for pure lighting or decoration.

Classifications of LED Flexible Strips
According to the waterproof grades, they can be divided into non-waterproof LED strips, dispensing waterproof LED flexible strips (waterproof grade IP55), half casing waterproof LED flexible strips (waterproof grade IP65), and full casing waterproof LED flexible strips (waterproof grade IP68). Among them, full casing waterproof LED flexible strips are divided into simple full casing LED waterproof strips, silicone filling LED waterproof strips, and filling silicone waterproof effect is obviously superior to simple full casing LED waterproof strips.
According to glue water material used for waterproof, LED flexible strips are divided into epoxy resin glue and silica gel. As to appearance and light effect, waterproof led Strip filled with silicone give out light with greater strength, and it feels comfortable, also taking the environmental protection idea into account. But it suffers one disadvantage, its weak flexibility and frangibility. In contrast, epoxy resin glue is chosen for most LED strips because it has better flexibility and is relatively inexpensive. Thus it is widely used.
According to the chips classes and the number of LED beads, LED flexible strip lamps are currently divided into common 3528 and 5050 these two types. Depending on the quantity of lamp beads per meter, LED strips are divided into: 30 lamps, 48 lamps, 60 lamps these common specifications. Because of its small power (0.06W), 3528 can be made to maximum 120 lamps/m.
According to circuit board width of flexible strips, they can be divided into 5MM, 8MM, 10MM 12MM, as well as 15MM waterproof LED strips.


Applications of Waterproof LED Strip
1. Home decoration;
2. Path indication and outer wall decoration;
3. Backlight illumination for billboard, advertising signs, aisle signs, etc;
4. Automotive chassis decoration, high mounted stop indication, auto body decoration, inner car decoration light, etc;
5. Holiday decoration, event venue decoration, show ground decoration, exhibition hall decoration;

The 3D Films History

3D films have existed in some form since 1915. It was prominently featured in the 1950s in American cinema, and later experienced a worldwide resurgence in the 1980s and 1990s driven by IMAX high-end theaters and Disney themed-venues. In the 2000s, 3D films became more and more successful. Here are successful 3D movies with their released years.

1839, British scientist Charles Wheatstone invented stereoscopic glasses according to the principle “the left and right eyes of the people watching the same image but producing different results”.
1922, the first 3D movie in the world "Power of Love" showed. Unfortunately, the film has been lost long ago. Early 3D movies are mainly to show the three-dimensional effect. It often happened that pointing to the audience with gun, threw objects to audience, etc.
1952, "Adventures in Africa" which was telling an African adventure was identified as the first-ever true 3D feature film. The film's slogan is "lion in your lap, lover in your arms".

1953, the "House of Wax" and a number of 3D horror films emerged into the golden age of 3D chip in the fifties of the last century.
1954, Hitchcock made the 3D version of "Telephone Murder” and it became as one of the best 3D movies.
In 1962, China's Tianma Film Studio produced the first 3D stereoscopic film "Magician Adventure". In 1982, Disney produced the short film "Magic Tour". Though this short film is only 16 minutes, mixed performances by CGI and live action, it also created surprising 3D effect.
In 1983, the 3D version of "Jaws Ⅲ" got $ 13 million at the first week.

In 1985, the movie "Magic Crystal Fighters" became the world's first 3D animated feature film.
In 2004, the first IMAX 3D film "The Polar Express" was born. It showed on ordinary 2D screen in 2000, and 3D IMAX screen which has only 75 pieces. But this kind of 3d holographic projection was a huge commercial potential for producers.
In 2005, Disney's animated film "Chickens Story” had a new projection technology screening to eliminate eye fatigue.
In 2008, "U2 3D Concert” is the first live-action film shot entirely in 3D camera.
…
Thanks to the projection screen manufacturers, we can enjoy more and more exciting 3D movies in theater and even at home.

Applicable Occasions of Induction Light

Corridor LED Human Body Induction Lights

Traditional induction lights are installed in the corridor and generally are composed of two parts, the human body induction panel switch and the light source, the light source is incandescent, and the two separated in housing construction should well equip the line and position. Incandescent tungsten cannot withstand frequent switch, so every year you have to replace the broken lights, and the artificial maintenance costs are too high. LED body induction lights have built-in light source and the human body sensing device, you only need to install the screw into the general E27 base, then you can reach the body induction lamp. The lights open when people come near, and when people go, the lamp will be out. The installation placed between the corner and down the stairs can response to the upstairs and downstairs, in addition to that the induction light source life is long, low-voltage operation, so the frequent switches do not have impact on it. Now the residential buildings is not the same as the conventional single-family detached, high-rise buildings in the estate, and there were several dozens of families, LED human sensor lights installed in each floor public corridor is very appropriate, whenever the owners come back home, or come out from the elevator, the LED sensor light will be bright, in the 1-minute time delay, the owners have enough time to open their own door and into the house.

Balcony LED Human Body Induction Light

In the past, the balcony lighting is an incandescent lamp or ceiling light. The balcony belonging to the semi-outdoor, when open the lights at night, mosquitoes and flies will turn around the lights, and do not remember in life from time to time off the balcony lights. If LED Ceiling induction bulbs or the human body sensors light bulbs are installed in this position, these two issues can be resolved, LED is a cold light source, no ultraviolet, will not provoke mosquito, intelligent sensing body in the balcony during light lit people left the lamp, and it is power-saving and convenient.

The Toilets LED Human Body Sensor Lights

Maybe you may ask: Isn't the LED human sensor lights installed in the toilets not afraid to wet? Do not worry. The housing of the lamp body is plastic, LED lamp beads are not afraid of humidity as the light source. When people are in the toilet, the light is in the lit state, when people walk away, since they do not have to switch, so they completely no need to worry the wet hands risk of electric shock.

Work Principle of CFL Energy-saving Lamps

The introduction of CFL lamps

Energy-saving lamps are called trichromatic electronic compact fluorescent lamps (CFL lamps), and it was first invented in 1978 by foreign manufacturers, because it has the features of high luminous efficiency (which is five times that of ordinary cfl lamps), significant energy savings, long life (is ordinary the lamp eight times), small size, ease of use, it is valued and welcomed by the peoples and countries, in China 1982, first in the Lighting Research Institute of Fudan University successfully developed the SL-type compact fluorescent lamps, the past two decades, the production rapid growth, steadily improving the quality, the state has as promotion and use it as the national focus on the development of energy-saving products (green lighting products).

The working principle of the energy-saving lamp

The working principle of the energy-saving lamp ballast to the lamp filament heated to about 1160K temperature, the filament began to emit electrons (because some electronic powder coating on the filament), electron impact inelastic collisions of argon atoms, argon atoms after the collision energy and the impact of mercury atoms mercury atoms absorb energy transitions produce ionizing issued 253.7nm UV ultraviolet excitation light-emitting phosphors, the fluorescent work filament temperature of about 1160K, the working temperature than incandescent 2200K -2700K is much lower, so its life span is also large, up to more than 5000 hours, because it does not exist as current incandescent thermal effect of electronic ballast, the energy conversion efficiency of the phosphor of electronic ballast is also very high, reaching more than 60 lumens per watt.

The information of ordinary incandescent light

Ordinary incandescent light efficiency is about 10 lumens per watt, and the life is about 2000 hours or so, it work principle is when the lamp is accessed to circuit, the current flows through the filament, and the heating effect of current incandescent issued continuous visible and infrared, this phenomenon in the filament temperature to rise to 700K can be aware of the work when the filament temperature is high, most of the energy is wasted in the form of infrared radiation. In quite a long period of time, some places and manufacturers have carried out the energy-saving lamp projects while capital, technology, raw materials and process have been not fully implemented, so that the product quality cannot be guaranteed, the quality of products for enterprises the imbalance, some manufacturers do not follow process requirements, lamps and components assembly plant selection undesirable patchwork composition, quality second lowest, serious damage to the reputation of the energy-saving lamps, the luminous efficiency is low, life is short, consistency, community energy-saving lamps Energy Saving money is not festival saying, bring a lot of negative impact to the promotion of energy-saving lamps.

www.thecfllamps.com, located in Foshan City, Guangdong Province, China, was set up in 2004. The company is specialized in R&D of Compact Fluorescent Light (CFL bulb), Electricity Distribution Box and light spare parts. There are more than 200 employees in our company, participating in electric lighting work, including R&D, assembling, inspection and packing, etc.

Teach You How to Buy LED Panel Lights

Current situation of LED panel light market

In recent years, since the rapid development of LED lighting industry, LED lighting product advantage has been recognized by the people, and also won the strong support from national government, directly benefit the lighting fixtures manufacturers producing LED panel lights. The energy-saving, environmental protection, high light efficiency, long life and other effects of LED panel lights attract many led panel light manufacturer to be actively involved in the LED panel light production factory ranks. Due to low LED lighting industry barriers to entry and blind investment of some manufacturers, it leads to the quality of LED panel lights on the market varies greatly, LED lamp prices also vary widely. With the development of the market, consumers have to polish your own eyes, calmly and scientific select the best cost-effective LED lamps.

LED panel lights are widely used in indoor lighting

LED panel lights are more and more widely used in the field of indoor lighting, but how to properly buy LED panel lights has become the problem that people are most concerned about. Let’s work together to understand the performance of the LED panel lights as well as how to purchase. We first directly see the quality of the LED panel lights from nine aspects.



1. Brightness. Different LED brightness, different prices. LED for LED lamps shall comply with Laser Class I standard.

2. Antistatic ability. LEDs with strong antistatic ability have long life, and therefore prices are higher. Usually LED static more than 700V can be used for LED lighting.

3. Wavelength. LED with consistent wavelength has the same color. If the color is required to be consistent, the price is high. It is difficult for LED Tube manufacturer who have no LED testing instrument to produce pure colors.

4. Leakage. Current LED is the one way conductive light, if there is reverse current, it is called leakage; the LED with large leakage current has short life, and available at low prices.

5. Glow. LED with different angle uses has different beam angle. Special light-emitting angle, the price is higher. If all diffusion angle, the price is higher.

6. Life. The key to different quality is life, and life is decided by the light fades. Small light decay, long life, long life, high price.

7. Chips. The light-emitting body of LED is a chip; different chips, the price varies greatly. The chips from Japan, the United States are more expensive, generally the prices of chips made in Taiwan are lower than Japan and the United States.

8. Chip size. The size of the chip is represented by edge length; big chip LED quality is better than the small chip. The price is proportional to the chip size.

9. Colloid. Ordinary LED colloidal is generally epoxy resin, the price of LED added with UV resistance and fire retardant is expensive, high-quality outdoor LED lighting should be UV and fire proof.

When will 5D Film Era Arrive in China

5D movie is originated in South Korea. In 2009, it was introduced into China. 5D movie containses all the features of the 4D Theater, in addition it has interactive features with using special effects seat and environmental effects 5D Movie Theater provides special surreal visual experience with irritating effect of vision, hearing, smell and movement.
In China, during recent 3 years development, 5D movies now have sprung up in the front-line city walking street, large squares, playgrounds and other places. But when will the the real 5D film era arrive? Let’s wait and see.

5D movies in China still have many shortcomings in the development process, mainly in the following aspects:

First, lacking of inter-disciplinary talents

The 5D movie is a combination of technology and culture. To produce the high quality of 5D movie, inter-disciplinary talents who master in movies and technology are needed. Right now the 5D cinema staffs are mainly technical personnel, which resulted in the 5D film re-simulated experience light film culture situation. It greatly reduces the 5D film appreciation and artistic value. Countries should vigorously promote the 5D film inter-disciplinary talent training and transport fresh blood for 5D movie.

Second, lacking of software device

The showtimes and independent scene both depend on the essence of the movie. The 5D requires better playback system than the traditional theater. Many devices on the market only do the traditional hierarchy true representation of certain constraints. Most of the audiences don’t have good review of the 5D movie, they even have uncomfortable feelings. The main reason is the device software is unqualified.

Finally, less inverstment of 5D cinema

Most of the 5d cinema equipment is now a mini-museum experience with smaller investment. However, the constructions of a 5D Theater cost millions and make many investors think it is a risk. The 5D cinema development needs huge funds to promote the integration of resources in order to accelerate the pace of development of 5D cinema with international standards. When the timing is mature, large-scale investments will become a necessity. The 5D movie will become a new growth point of the Chinese film and its development prospects are very impressive. 3D movies in the Chinese market in 2008 set off a digital film revolution. Two years later the emergence of the 4D movie completely attracted the attention of the audience. The 5D movies will directly replace 4D movie. But in domestic 5D movie is still in its infancy, there is a long distance away from the popular stage in the development process. We have to constantly improve the technical level to enhance the combination of strengthening 5D movie technology and art.

www.5d-theater.com is located in Guangzhou, Guangdong. We mainly supply all kinds of digital video equipments. We are dedicated to pursue client expectation and provide reasonable price with the best service.

The Industrial Characteristics of LED Products

The prices of mainstream products LED

Currently, the price of the 1W white LED with the luminous flux of 70 ~ 90lm in the market is basically maintained at 17 yuan, and the price of the domestic production of High Power LED is basically 5.50 yuan. Along with the rapid growth of its luminous efficiency of the power white LED applications upgrade, the single LED prices are expected to gradually be reduced.



Second, costs and the heat dissipation is still the biggest obstacle to replace the traditional lighting.

Lighting is the most attractive application field for LED, the cost is critical for the LED to replace traditional lighting. Relative to its exponentially in the service life of traditional lamps, the price of LED is not high, and can save the costs late replacement and maintenance, but the start-up costs are often subject to direct purchase budget. Mingxue Optoelectronic believes that the main bottleneck impacting the current LED applications lies in the lumens cost is 10 times more than traditional lighting source. So the light efficiency has to be improved to 150lm / W, and drive current is promoted from 700mA to 2A, at the same time the die and package cost will be reduced by half, which can obtain the popularization and application in the field of lighting to large-scale. The LED package is to integrate light and heat in a single device, and heating will bring the largest impact on the led power supply devices, if the lighting is alway in the case of the high-temperature, it will greatly affect the life of the lighting devices or fixtures, LED lighting package structure poses a severe challenge.

Third, the prospects of high-power LED domestic market is broad

Currently, landscape lighting market is the largest high-power LED lighting applications market and its share is about 43%. It's a new round of rapid growth is bound to bring a new impetus to the development of high-power LED lighting industry. In addition, through the positive improvement of the global high-power LED technology leader in materials, processes and packaging technology, high power LED luminous efficiency and performance is increasing very fast, high-power LED has begun to go into the indoor and outdoor general lighting, automotive interior and exterior lighting, searchlight and other new markets. The high-power LED lighting industry will obtain the development by leaps and bounds in the next 3 to 5 years, to subvert the traditional lighting industry pattern.

LED Lamps Export "New World" Emerges

China LED Lamps Export Status Quo

Even when the market remains in the doldrums, and under the context that the export ports of Europe and the United States are blocked, domestic lighting export growth momentum remains good. Seen from the export product composition, incandescent export is essentially flat with last year, the energy-saving lamps exports declines by 1.4%, fluorescent lamps exports declines by 6.5%. In addition to the remarkable LED growth lighting products, other categories have shown a downward trend. China's exports accounted for 30% of the global lighting trade volume of lamps. Which compact fluorescent lamps (CFL) and Christmas lights occupy more than 80% share of the global market, the incandescent also accounts for 1/3 of the global market share, and the proportion is still expanding. Since 2008, the domestic LED industry is booming, there is huge market potential, attract domestic and foreign enterprises in this land staking siege slightly pools. In just a few years time, China has become the world's largest led lighting residential fixture exporter.



Short Board of LED Lighting Export

Related statistics show that the third quarter of 2012, the port of Xiamen LED kitchen downlights exports grew five-fold to $ 70,110,000; Hangzhou LED lamps and lanterns exports reached $ 100,000,000, an increase of 34.67%; Shaoxing LED lamps exports amounted to $ 69,440,000 , with an increase of 133%. LED lighting is in a relatively weak market environment, against the trend. As for the export geographical constitute, the United States is topped, accounted for 20.20% of total exports; followed by Japan and Germany accounted for 17.2% and 7.6%, respectively; Although Hong Kong has a large export volume, but is mainly confined to the re-export trade. Although the United States is the largest exporter of domestic LED lighting, but the barriers to entry are relatively high. LED lighting products in order to enter the United States of super retail channels, they need to obtain the UL and Energy Star certification. Meanwhile, the U.S. government introduced subsidies for LED lighting products, which led directly to the lower price of LED lighting products, only to take the path of "puerile". In the Japanese market, the 2013 years, the export situation will undergo great changes.

The LED Fixtures Export "New World"

During the first three quarters of last year, both the U.S. and European markets, the Japanese market, LED export has a contrarian growth. However, to enter the market, it is inevitable to encounter technical certification, especially patent lack of distress, making the export of domestic LED enterprises frequently blocked. In recent years, Russia, Thailand and Africa LED demand have become a new LED lighting export market. Southeast Asian market demands for great LEDs, and the policy is very attractive. The statistics show that of the relevant bodies, Thailand lighting market size is about 1.4 billion RMB in 2012 to about 12%, including LED, expected by 2015, the proportion will increase to 45% -50%. More important, as long as the Chinese enterprises get the certificate of origin of the domestic LED products export to Thailand can enjoy zero tariffs, but the price of Thailand is 2 times of China’s. The products exported to Thailand, only those through the Thai the TIS system of certification (similar the domestic CCC certification) can be sold in the Thai market.

The Impovement of LED Spot Lighting

LED point light source is a point light source, if the application is not good, and prone to glare from the whole industry chain, LED lights, radiator, drive, replace all of the high-pressure sodium lamps cost is not necessarily cheaper. Hangzhou Bulletin the Wu Ming Fan, LED spot light, director of the Institute, the LED lamp technology requirements, require advanced large-scale replacement.

In addition, the indicators of the evaluation of road lighting “illumination” are better than “brightness”. The various little throat professor pointed out that LED spot lighting can be replaced by the brightness of the light distribution to achieve the bat LED spotlights. The actual situation The brightness expensive measuring instruments penetration is not high, so for the convenience of the general lighting, rather than brightness. The evaluation system is flawed, difficult to guarantee the quality of LED lights.



Promoting the dimming LED spot light renovation project for the government of the most powerful companies also has their own views. "Subsidies to promote government can solve the urgent needs of the enterprise, but need the ability to save the government project eligibility successful product in the end simply different, and to rely on time to test. " said by a street lights manufacturer, who worried that the government palliatives, excessive administrative intervention may become secondary LED street light manufacturing industries. At the same time, he also pointed out that the face of the impetuous market, and companies need a clear direction of their own development, rather than the government-supported projects.

Living in a green manner is not always as straightforward as we’d like it to be, certainly if the media is anything to go by. Obviously, given the choice, many of us would want to affect a positive change where the environmental issue is concerned but beyond this desire to do the right thing, it can be hard to know what changes you can make which will make a decent difference.

U.S Scientists have Developed Warm White LED Light New Materials

Warm white LED lights have been developed

As we all know, LED (light emitting diode) lights are energy efficient and have longer life expectancy, but the current LED lights are mainly light blue luminescent lights, which hindered its popularity in the field of indoor wholesale lighting. Today, warm white LED lights have been developed by scientists at the University of Georgia, USA, which are said to be the world's first to use single phosphor and single light-emitting unit. The paper details about this material are published in the latest issue of Optical Science and Applications journal of Nature Publishing Group.

Two indicators to measure the quality of artificial light

The paper's lead author, Pan Zhengwei, associate professor at the University of Georgia said: "At present, the white LED lamp is used on flash and auto headlights, the light blue luminescent they emit is less likable, especially in indoor lighting field. Our materials have achieved warm color temperature, while at the same time achieved a realistic color reproduction. The LED lights earlier improved using single phosphor failed to achieve this effect. "Pan Zhengwei said, there are two indicators to measure the quality of artificial light. Correlated color temperature is used to measure the well-being of the light. For indoor lighting, color temperature lower than the temperature of 4000K (Kelvin) is ideal and correlated color temperature higher than 5000K, the light will emit light blue luminescent like white LED t5 light fixture. Another important indicator is the color reproduction that is the ability of the light source to simulate natural light. Reduction degree reach more than 80 is ideal for indoor lighting, below this value the color will be very distortion.

The material developed by Pan Zhengwei and his colleagues meet these two conditions, correlated color temperature is controlled below 4000K and color reproduction reaches 85. Pan Zhengwei said coat the outer layer of blue LED chip with different colors phosphor is able to issue warm white light, which would then make phosphor-based white LED lights. However, these raw materials are laborious and cost money in accordance with the precise ratio, and eventually the light color will be different, because each raw material has not the same reaction to temperature change. One of the authors of the paper, Doctor Li Xufan, Engineering of the University of Georgia in Reading said: "Using single phosphor can solve the problem of instability in the light color, because single material does not change as the temperature rises."

The new material still needs to solve some problems before being applied in lighting

In order to develop new phosphors, Pan Zhengwei and his team selected europium oxide, aluminum oxide, barium oxide and graphite, each of which are taken to a small amount and mingled together. Then they put these powdery materials into a tube furnace and heat to 1450 degrees Celsius. The vacuum state in the furnace makes the vaporized material onto the chassis, and deposited as yellow light-emitting compound, and then put inside the bulb. Though research results are promising, Pan Zhengwei stressed that they need to resolve a few problems to apply this material in the lighting for homes, businesses and schools. The luminous efficiency of the new material is much lower than the light blue white LED lights. In addition, large-scale production will face challenges.

Programs to Increase LED Tube Service Life and Brightness

If LED tubes need to maintain the long life and high brightness, the problem to be solved is that the four key technologies: power, LED light source, cooling, security.

1. Power supply The first requirement for power is high-efficiency, high-efficiency products had low heat, and the stability is bound to be high. Usually isolated and non-isolated two programs are used for power section; isolated volume is too large, less efficient, which will create many installation problems in use, and don't have large market prospects as non-isolated products.

2. LED light source The LED light source using Taiwan Okinawa Cummings patent structure, its chip is placed at the pin, thermal silver foot directly bring out the heat generated by chip node, which is qualitatively different with the traditional DIP products, and patch products in the heat; the nodes temperature of the chip is not cumulative, to ensure good use of the light source lamp beads, to ensure the long life of the light source LED, low light failure. Traditional patch t8 led tube light products connect positive and negative through chip gold, but also connect the heat generated by the chip over gold wire to the silver feet, thermal and electrical conductivity are conducted by gold wire, and the heat accumulated over a long time will directly affect the life of the LED Tube.



3. Heat dissipation Introduce and apply infrared heat radiation to fluorescent tubes is an important means to improve lamp life. In thermal considerations, we distinguish LED light source lamp beads cooling heat and power, not disturbing each other, in order to ensure the reasonableness of the heat dissipation. There are three ways of heat conduction, convection, conduction and radiation. In a closed environment, the convection and conduction are less possible to achieve, dissipate heat by radiation is key consideration for the tubes.

4. Security Security, PC flame retardant plastic tube, because the infrared heat can penetrate the PC tube, when we design and consider t8 fluorescent tubes use, we need to pay more consideration to their safety, all-plastic physical insulation, that is to use non-isolated power supply can absolutely guarantee the safety of use. LED tube development has been quite a long time, from the energy-saving effect of view, its future application surface is quite broad, in addition to energy saving, their safety, the use of long-life is what we should be concerned! Safety is the first element in the design of the LED tubes.

Several Keys to the High Quality LED

Third-party testing

In order to eliminate the injustices that exist in the test, many companies have commissioned a third party to test LED assembly and circuit structure. In the testing process, and at the same time, pressure, temperature cycling, fixed voltage / change current fixed / change test and the test in other harsh environmental conditions decide whether the LED(such as flexible led strip lights) meets the requirements of the application. The occurrence of the large number of parameter changes before and after the test should be recorded while monitoring the changes in the measured LED brightness, color, and the voltage drop. In addition, the assembly technology has more impact than the performance of the LED chip to some extent. The design engineer should ask LED suppliers for the LED reliability specification, and LED assembly should be tested to ensure higher brightness. Some good LED suppliers can ensure the reliability of the LED assembly technology for three years or longer, and can provide high quality LED and the appropriate design for specific applications, including the final LED products.



The importance of LED detection

In the early 1990s, LED was used in the brake lights for cars and trucks. Some LED design soon appeared inconsistency on the performance indicators, and soon be burned down, the reason may be the led power supply quality, perhaps completely the design of the product. Until now, in the traffic lights, LED becomes more suitable light source, and this phenomenon was only great importance. If the stress tests or accelerated life cycle testing has been done, then LED or LED assembly can be considered as high-quality or qualified, and can be used in reliability occasion.

Rational usage of LED

Not every application needs high-quality LED assembly technology. If the assembly of the LED does not meet the requirements of the harsh environment, the application does not have larger security risk, or, if the maintenance costs of the final product are not very high, the use of the differential of some of the assembly technique may be more appropriate.

The cost of LED light

The most fundamental content is the LED must be affordable. So, in the limit of cost requirements, it is necessary to consider the level of supplier product packaging, assembly design experience and testing. The design that meets the application and market demand is the most effective means of service to end users. If the application requires high-end solutions, the chip vendor selection, design experience, and tests are the factors that you should consider. If you do not consider the sales price of the high-end products, you should consider very carefully the difference between good and bad LED other relevant factors. LED suppliers with packaging grade classification ability, as well as to the reliability, accelerated life cycle testing vendors is a long-term cooperation, which helps manufacturers with a more reliable LED develop high-end products.

www.ledlightmx.com has won SGS/ISO9001: 2008 international quality management System Certification, SGS certificate of heavy metals, cadmium-free lead-free process requirements, and has got LED lighting products certification, CE, RoHS.

China Wire and Cable Industry usher in New Business Opportunities and Market in 2013

China's wire and cable industry will usher in new opportunities and markets

With the arrival of 2013, China's wire and cable industry will usher in new opportunities and markets. With the continuous expansion scale of China's power industry, the data communications industry, urban rail transit industry, the automotive industry, as well as shipbuilding and other industries, the demand for wire and cable will also grow rapidly, driving the development of China's wire and cable industry. 2012 was a threshold for the electrical wire supplier, due to the slow-down in GDP growth, the global financial crisis, the domestic economic structure adjustment and other reasons, it resulted the universal operating rate of domestic cable prices and overcapacity, even once caused the industry worries closures.

Current situation of China wire and cable industry

At present, the scale of the global wire and cable market has more than 100 billion euros, and in the range of the global wire and cable industry, the size of the market in Asia accounts for 37%, the European market is close to 30%, the American market accounts for 24% and other markets account for 9%. Among them, China's wire and cable industry plays an irreplaceable role in the global wire and cable industry, and the output value of China's wire and cable companies has surpassed the United States early in 2011 and ranked first in the world. Objectively speaking, compared to the fiber optic cable manufacturer in Europe and North America, China is still is still in the situation of big but not strong, and there is a big gap with foreign well-known wire and cable brands.



Reason why there is a big gap between China's wire and cable industry and foreign well-known wire and cable brands

The reason for this situation is because China's wire and cable industry manufacturing scale is improved at an alarming rate, technology and product upgrades are far behind the pace of the market, resulting very serious industry redundant construction, and form capacity excess, lack of effective supply, structural contradiction, the low input-output, weak scientific and technological innovation. Wire and cable industry is a systems industry, from the smelting of industrial raw materials, through product design, prototype to mass production of the finished product, testing, use and integration, even the development of recovery and recycling of products, which is an extremely complex process . Seize the era of blind expansion, extensive development, despite the economic benefits obtained in a short period of time, but it is difficult to form a scale, a brand.

It is because most of the wire and cable business pursue for short-term economic interests, thus causing the wire and cable in China today is facing a severe test. Technological innovation and product innovation don’t keep up with, the market lack of innovation, missing management system all hinder the development of China's cable prices, which is the root cause why it is difficult for China's wire and cable industry to form their own international brand. With the continuous development of science and technology and the advance of the process of industrialization, the requirements for wire and cable products increase, if the cable enterprises cannot produce wire and cable products to meet the requirements and meet the standards, they are bound to be eliminated.

Some Basic Knowledge about Film Capacitor

The introduction of the metallized film capacitor

The films used in the metallized film capacitor are polyethylene ethyl acrylate, polypropylene, polycarbonate, etc., in addition, there are also the wound-type and the stacked type. This type of metalized film capacitors of film capacitor manufacturers has the role of the so-called Self Healing Action, which assumes a tiny part of the fragile quality of electricity sector and cause a short circuit, caused by a short circuit around the electrode metal part of the electrode, or short-circuit current due to the electrostatic energy of the capacitor brought, and lead to the dissolution of the larger area integration evaporated to recover the insulation, make the capacitor again return to the role of the capacitor.



The features of metallized film capacitor

Metallized film capacitor that is taking the surface of the polyester film of the vapor-deposited layer of metal film as the electrode to take the place of the metal foil, because the thickness of the metal film layer is much thinner than the thickness of the metal foil, the wound volume is much smaller than the metal foil capacitance. The biggest advantage of metalized film capacitors is a "self-healing". The so-called self-healing property is if the thin film dielectric shows the phenomenon of short-circuit breakdown because the defects are in the presence of some points, and the condition of over-voltage, and the breakdown point metal layer may be in the arc under the action of an instant melting evaporated forming a small non-metallic area , the capacitance of the two pole pieces are re-insulated from each other and can continue to work, thus greatly improving the reliability of the work of the plastic film capacitor. Analysis from the above principle, metalized film capacitors should not have the short-circuit failure mode, while there will be a lot of short-circuit failure phenomenon in the metal foil capacitor.

The disadvantages of the metal film capacitor

Although the metal film capacitors have the great advantages as described above, but compared with the metal foil capacitor, there are the following two disadvantages: First, the capacity stability is poorer than a foil type capacitor, which is because in the long working conditions, the metallized capacitor is prone to capacity loss and the capacity will be reduced after healing, therefore, the metal foil capacitor should be better used in an oscillation circuit with the higher demanding in capacity stability. Another major drawback is the large current capacity is poor, which is because the metalized film layer is much thinner than the metal foils, and the ability to carry large currents is weaker. To improve this shortcoming of the metallized film capacitors, metalized film capacitors in high-current products in the manufacturing process has been improved, and the major improvement ways are: first, take the use of the double-sided metallized film as the electrode; second, increase the thickness of the metallization layer; third, the end face of the metal welding process improvements to reduce the contact resistance.

For film capacitors, www.film-capacitor.nets dielectric materials are polyester film, polypropylene film and the dielectrod is envaporated metal layer or Aluminum foil or Zine-Aluminum foil. And the construction is wound or stacked.

Method to Develop the Film Capacitor Industry

Analysis of the current capacitor industry

With the shortening of electronic machine replacement cycle, the demands for compact size and digitization are increasing, and currently, the momentum of development of the organic thin film capacitors chip is strong, and there is a general trend to gradually replace the traditional lead film capacitors.

If capacitor manufacturers want to shorten the distance between the international market and domestic capacitors enterprise, we should focus on the following issue:
First, focus on the research and development of key film capacitors.

Second, pay attention to the technological innovation, patent declaration and the trademark protection work.

Third, strengthen information research, and improve the level of information, in order to provide strategic ideas for technology research and development, market development, and economic development in a timely manner.

Fourth, attention should be paid to the implementation of brand strategy, strive to create a well-known international brand, and strive to improve enterprise comprehensive strength and level.

Fifth, promote the research and production of film capacitors. The development of the domestic chip film capacitors is in its infancy, and there is the trend to gradually expand the market share and take the place of the traditional lead plastic film capacitor. Who takes the first action, and who will be able to seize market opportunities.

Sixth, use various means to make the enterprises bigger and stronger. The domestic film capacitors enterprises can learn from foreign experience and the enterprises with strong strength can make the independent research and development to the raw materials and the electronic machine, and to form combination electronic materials and electronic machine manufacturers. And we can expand enterprise scale and improve the ability to resist risks in the international market competition through a variety of ways of mergers, acquisitions and coming to the market both at home and abroad.

Seventh, establish its own technological innovation and product research and development system, to enter the field of high-tech and high-tech products, and gradually form their own core competitiveness.

Eighth, create a marketing team at the top level.

Ninth, pay close attention to the international market dynamic and establish sensitive and efficient early warning mechanism.

There is no doubt that the prospect of film capacitors is promising, so we have to make efforts to research and study on the advanced technology and means to reduce the cost of the raw materials to take more share in the market.

The Importance of RFID Tags for Laundry

RFID for Industrial Laundries

Industrial laundries recognized the benefits of using RFID to manage large scale laundry operations many years ago. Commercial laundries process thousands of pieces each hour for multiple customers. It is estimated that there are more than 400 million uniforms and other garments that are rented in North America and Europe. 20% of workers wear rented uniforms and this number is growing by 15% annually. All these uniforms need cleaning. All these cleaned uniforms have to be returned to the right customer.



The Beginning of RFID for Laundry

When the industrial laundries began using RFID the only suitable and available technology was HF (13.56 MHz) RFID. Laundry operators created portals. An RFID portal is a read station made up of an RFID reader with an array of antennas. The RFID tags are usually sewn into the garment. To manage the flow of all uniforms and garments through a laundry facility every rfid laundry tag is read as each item passed through the different stages of the operation. Typically read stations would be located in receiving, sorting, cleaning and washing, drying, ironing, folding, sorting, shipping and delivery. The tags must withstand the chemicals used in the washing and cleaning process. The tags must also withstand the washing, drying and ironing temperatures and the tags must outlast the life of the garment.

UHF RFID is introduced for Laundry Security in Hotels

A new RFID standard was approved in December 2004: EPC Gen 2. The new standard has resulted in changes in RFID capabilities and price. The Gen 2 RFID tags cost less than HF tags and the read range of the tags has increased from what were centimeters to meters or inches to yards. Most new laundry implementations are taking advantage of this recent development in RFID technology. Hotel linen includes hand towels, sheets, pillow and many other items. Some hotel guests are involved in taking up one or two of them back to their home. To some, theft of hotel towels is more pastime than petty crime. Hotels, on the other hand, apparently take it more seriously. UHF RFID laundry tags can be sewn directly into towels, bathrobes or sheets, and can report whenever an item leaves a hotel's premises. The uhf rfid tag when read by strategically placed RFID readers can set off an alarm, usually silent, that will instantly alert the staff that a hotel item has ‘grown legs’.

RFID standard is forthcoming

RFID as a key technology of the Internet, the concept to encode every grain of sand has been nearly 10 years. However, when the domestic industry is reaching maturity, RFID GB has been slow to keep pace. The reporter learned from the seventh China radio frequency identification technology development international seminar held in Shanghai that the domestic RFID standard is forthcoming.

RFID GB is expected to be introduced within 2 or 3 months

In fact, the news about RFID GB introductions was on newspapers as early as in 2004, followed by numerous reports about the message of "Dystocia". Would the introduction of GB be a "wolf coming"? In this regard, Jijing Qiu, the Secretary General of the China RFID Industry Technology Innovation Alliance told the reporter that RFID GB is expected to be introduced within 2 or 3 months, mainly carry out unified standardization on some basic standard data format, communication protocol and basic safety system. Currently, after RFID technology entering into applications, a number of application standards can also by developed by the industry, such as dangerous goods logistics tracking and electronic tickets, which already have normative application standard.

China must establish our own RFID standards

At present, the world has multiple RFID international standards, whether there is a need to have our own standards? Ji Jingqiu thinks that RFID technology and industry in China already have a certain level and scale, the benefits of RFID card are directly related to the volume of information and applications that are programmed for use on a card, so we must establish our own standards. In addition, taking information security into account, the use of someone else's standards is equal to allow others to "read" our own items, and pay for others.

China RFID production can meet future market applications

The current promotion of RFID applications is in the face of the standards, cost, business model, security hot issues, and the cost is considered to be a "stumbling block" of RFID promotion. Ji Jingqiu said that domestic RFID industry chain develops very fast, each label can already do 0.4 RMB, and we can produce 6 billion labels each year, to meet future market applications.
