Advantages of led light
1.high luminous efficiency
After decades of LED technology improvements, the luminous efficiency has 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 into heat loss . LED luminous efficiency will be improved to achieve up to 50 ~ 200 lumens / watt, and its light color is good, narrow spectrum , can be sent directly without filtering colored visible light. Currently, countries in the world are stepping up to improve efficiency LED light research, in the near future there will be greater luminous efficiency improvement .
2.environmental protection
LED light for the whole solid , shock, impact resistance not broken, waste recycling, no pollution. Light, small size , can mix , easy to develop into short small thin portable lighting products, but also easy to install and maintain. Of course, we consider the use of energy-efficient LED light source is the most important reason , perhaps the LED light source expensive than traditional light sources , but with one year investment in energy-saving light sources to recover , resulting in 4 to 9 years of annual net saving several times .
3.long life
Electronic light field radiation emitting filament light easy to burn , heat deposition , the light attenuation and other shortcomings. The use of LED lights, small size , light weight , epoxy resin, high strength to withstand mechanical shock and vibration , easily broken. The average life of 100,000 hours . LED lamp life of up to 5 to 10 years, can significantly reduce lighting maintenance costs and avoid the pain of frequent lamp replacement .
4.strong security and reliability
Low heat , no heat radiation , cold light source , can be safely arrived touch: can precisely control the light pattern and light angle , light color and soft , no glare ; no mercury, sodium and other potential health hazards of substances. Built-in micro-processing system can control the light intensity, adjusting light way to achieve light and art .
5.less power consumption
LED single tube power from 0.03 to 0.06 watts, DC drives, single -tube drive voltage of 1.5 to 3.5 volts, the current 15 to 18 mA , fast response , can be operated at high frequency . The same lighting effect in the case , the power consumption is one-eighth of incandescent bulbs , fluorescent tubes half of Japan estimates , such as using fluorescent light efficiency is even higher than twice the LED replacement of incandescent and half of Japan fluorescent lamps. Annual savings equivalent to 6 billion liters of crude oil. On the bridge parapet lights case , the same effect a fluorescent 40 watts, while the use of LED only 8 watts of power each , and can be color changes.
