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.
