1, LED with high luminous efficiency
After decades of technological improvements, LED luminous efficiency have been greatly improved. Incandescent, halogen light efficiency is 12-24 lm/W, fluorescent light 50-70 lm/W, sodium 90 ~ 140 lm/W, most of the power loss into heat. Improved LED luminous efficiency will be to achieve up to 50 ~ 200 lm/W, and the monochromatic light is good, narrow spectrum, can be directly visible without the issue of color filters. At present, all countries in the world are stepping up to improve efficiency of LED light, in the near future, its luminous efficiency improvement will be greater.
2, LED light source power consumption less
The consumption of single LED is 0.03-0.06W, use DC-driven, single LED drive voltage is 1.5-3.5 V, current is 15 to 18 milliamperes. With high reaction speed, can be operated at high frequency. Under the same lighting effects, the power consumption of LED is one-eighth of incandescent bulbs, half of fluorescent tubes, the Japanese expert estimates, if the use of LED lighting to replace half ofthe incandescent and fluorescent light in Japan, It will save 6000 million liters crude oil annually. To the bridge lights as an example, one 40W fluorescent lamp can be replaced by one LED light with only 8 watts, and also the LED lights can change color.
3, LED light source with long life span
If use electronic radiation emitting light, light emitting filament burnability easily, heat deposition, with shortcomings of optical attenuation. But use of LED lights are small, light weight, epoxy package and can withstand high-intensity mechanical shock and vibration, hard broken. The average life expectancy of up to 100,000 hours. Life of LED lamp up to 5-10 years, the lamp can be significantly reduced maintenance costs.
4, LED light source safety and reliability
Low heat, non-thermal radiation, cold light source, can be touched safely: can accurately control light pattern and the light angle. Light color and soft, non-glare; not mercury, sodium and other elements may be hazardous to health. With built-in micro-processing system can control the luminous intensity, adjusting the light-emitting modes to achieve light with art.
5, LED light source is beneficial to the environment
LED luminous body is solid, quake resistance, impact resistance so that not easy broken, recyclable and no pollution. Small light source, can be easily produced into smart and portable lighting products, and also easy to install and maintain.
Of course, the energy-efficient is the main reason for us to consider the LED as light source, may be LED is more expensive than traditional light sources, but within one year it can recover the investment of replace new light source, more result 4 to 9 years for energy saving.
