What are the main manufacturers of LED light sources in China?
At present, the domestic LED light source manufacturers can be divided into the following three categories to understand:A point light source manufacturers: country star, billion light, Hongli that several of the LED light source was the most famous.Two, the integrated surface light source: manufacturers, Guangyu integration, surface light source is delicately made.Three, distributed integration (the latest patented LED light source): World photoelectric
The LED light source is the light source of the light-emitting diode (LED). Light emitting diodes (LED) were invented in 1960s, and for the next few decades their basic use was as an indicator for electronic devices such as recorders. This kind of bulb has the characteristics of high efficiency and long service life. It can be used continuously for 100 thousand hours, 100 times longer than ordinary incandescent bulb. Scientists predict that in the next 5 years, this light bulb is likely to become the mainstream of the next generation of lighting products.
1 、 high luminous efficiencyAfter several decades of technical improvement, the luminous efficiency of LED has been greatly improved. Incandescent lamp, halogen tungsten lamp, light efficiency of 12-24 lumens / watt, fluorescent lamp 50~70 lumens / watt, sodium lamp 90~140 lumens / watt, most of the power consumption into heat loss. The LED light effect will be up to 50~200 lumens / watt after improvement, and its light color is good and the spectrum is narrow. Without filtering, it can directly emit colored visible light. All countries in the world have stepped up their efforts to improve the LED light efficiency, and the luminous efficiency will be improved in the near future.2, less power consumptionLED single tube power 0.03 to 0.06 watts, using DC drive, single tube drive voltage 1.5 to 3.5 volts, 15~18 ma current, fast response, can be operated at high frequency. The same lighting effect, power consumption is 1/10000 of incandescent bulbs, fluorescent tubes, 1/2 Japanese estimates, such as the use of incandescent lamp and fluorescent lamp fluorescent lamp with high light efficiency more than two times the LED replace half of japan. It can save up to 6 billion litres of crude oil a year. Bridge guardrail lamp, a fluorescent lamp of the same effect more than 40 watts, and the use of LED power each only 8 watts, and color change.3, long service lifeIt uses the electron light field to radiate light, and the filament has the advantages of light emitting, easy burning, thermal deposition and light attenuation. The LED light, small size, light weight, epoxy resin package, can withstand high mechanical impact and vibration, not easy to break. The average life span is 100 thousand hours. The service life of LED lamps can be up to 5~10 years, which can greatly reduce the maintenance cost of lamps and lanterns, and avoid the frequent change of lamps.
