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.

Classification of PVC Cards

First, screen printing PVC card

PVC card taking use of screen printing is the most common printing method, the operation is more complex in the traditional process, but investment is less in equipment. It has the widest range of applications, which accounts for a large proportion of PVC card. The screen printing cards are mainly used to make gold and silver card. It is only applicable to the large volume production of a simple card and the signature strip on the back of the card as well as printing, such as simple text and graphics, while it cannot be printed the high-quality color pattern.

Second, color offset printing PVC card

At present, color offset printing PVC card is the card type which is the most widely used. It generally uses four-color printing presses to print with UV offset ink. The finished is colorful with good clarity, high quality and it is suitable for high-volume printing. The most widely used presses are Japan AR010 series, if the printing volume is not large, we can also choose the appropriate domestic small business card presses to print.

Third, stamping gold and silver PVC card

Stamping gold and silver card is to use a dedicated bronzing machine to stamp text and graphics on the surface of the PVC card to form the PVC card with high metallic luster. Usually, it is used for VIP cards, discount cards, VIP membership card and so on. If you make a semi-finished blank PVC gold and silver card, it can be produced just by a bronzing machine. It does not require laminating machines, equipment investment is the least and it is affordable.

Fourth, color portrait PVC card

Color portrait card is a personalized card, and the surface of each card is recorded with different information and content, which card accounts for a large proportion in PVC card. There are two ways to produce PVC color portrait card: one is to use thermal transfer card printer to print directly on the surface of the blank card, while the costs are higher; the other is to use a color inkjet or laser printer to print special PVC film base, together with the traditional hot (Laminating machine) method. And it can produce the finished product after hot pressing and punch, the production cost is very low, and it is currently the most popular on the market, which is commonly used to produce a work permit, appointment cards, ticket, badges and other kinds of personalized cards.

The Safety of RFID Credit Card

RFID credit cards use a radio frequency to transmit personal financial data. They are not swiped through a scanning machine like a traditional credit card. Unfortunately, RFID credit cards can be skimmed when an unauthorized user grabs the unencrypted data from your card using an RFID reader. The technology Website EnGadget found that data from RFID credit cards is easily skimmed using an $8 reader purchased on eBay. Credit card companies and RFID Card Manufacturer are aware of the problem and are creating security fixes, but there are a number of steps you can take to protect your financial information.



Tips for Protecting Your RFID Credit Card

1. Leave your RFID credit cards at home. If you are concerned about the safety of your information on your card, use it only at home for online purchases. Pay for purchases outside your home with cash or regular credit cards.

2. Stack your RFID credit cards together in your wallet. Putting your cards next to one another will make it harder for a scanner to read the data on a particular RFID Card. However, this only offers a small amount of protection.

3. Wrap your RFID credit cards in aluminum foil before putting them in your wallet. Some users have reported that this simple, homemade technique helps block RFID scanners from reading the card.

4. Consider a credit card shield for more advanced protection. There are a number of companies that manufacture shields that hold your credit card when it is not in use. Most companies use aluminum material to prevent RFID scanners from reading the data on your card, and they usually cost less than $10.

5. Consider a special wallet, such as a DataSafe wallet, if you would prefer not to have a separate shield for each individual credit card. These wallets look completely normal, but they are manufactured with materials that have been approved by the Government Services Administration to block RFID transmissions.

6. Monitor your credit card statements regularly for errors or odd charges. Credit card theft and fraud can occur even after taking the best precautions, but regularly monitoring your bank statements can alert you to any suspicious activity.
