1, LED light -emitting efficiency of the high
Luminous efficiency comparison: incandescent, halogen light efficiency is 12-24 lm / W , fluorescent 50-70 lumens / watt sodium 90-140 lm / W, most of the power into heat loss .
LED luminous efficiency : can be sent to 50-200 lm / W , and the luminous color is good , narrow spectrum without filter , can be directly emit colored visible light.
2, LED light source low power consumption
Single tube 0.03-0.06 W power LED , DC drives, single -tube drive voltage of 1.5-3.5 volts. Reflect the current 15-18 mA fast in the high-frequency operation, with the same lighting effect in the case , the power consumption is one millionth of incandescent , fluorescent tubes half Japanese estimates , such as the use fluorescent light efficiency even higher than 2 times the LED replacement of incandescent and fluorescent lamps in Japan half a year can save the equivalent of 6 billion liters of crude oil, the same effect of a fluorescent 40 watts, while the use of LED power only 8 watts each .
3, LED light long life
Incandescent, fluorescent , halogen light field is the use of electronic radiation emitting filament light easy to burn , heat deposition , the light attenuation characteristics, and the use of LED lights, small size , light weight, epoxy resin, high strength to withstand mechanical shock and shock , not broken , the average life expectancy of 100,000 hours , LED lamp life of up to 5-10 years , can significantly lower lighting maintenance costs alone to avoid the pain of frequent lamp replacement .
4, LED light source safety and reliability
Low heat , no heat radiation, cold light source, can be safely arrived touch, can accurately control the angle of the light pattern and light , color and light , no glare , no mercury, sodium and other potential health hazards of substances.
5, LED light source of environmentally-friendly
LED light-emitting body for the whole solid , impact-resistant unbreakable , recyclable waste , no pollution and reduce the amount of sulfur dioxide, nitrogen dioxide and other harmful gases and other greenhouse gases produced to improve the living conditions of people's lives , can be called " green lighting ."
Production of high-brightness white LED light intensity 1:2:0.38 mixed in the ratio from white , two kinds , the use of ultra-high InGan blue LED, add a little of its total drill pipe yttrium garnet phosphors as the main body , it can in the blue produce excitation yellow green , yellow green and this can be synthesized with a revealing blue white , three are non- system UV LED, using UV -excited phosphor powder or other phosphors to produce multicolor mixture of white light.
6 Of course, energy efficiency is the most important reason we consider the use of LED light source , LED light than conventional light sources may be expensive, but with energy-saving light year payback time , thus saving a net gain of 4-9 years, several times a year closing the lid on .
