The great advantage of LED lights

　　Energy for sustainable development is no longer an optional issue, but the future development of the world will line the road . LED lighting as the representative of the new lighting to replace traditional light sources , is causing a huge change in the lighting industry .

　　( 1 ) Energy conservation : Most people believe that the energy-saving lamps can save energy 4 /5 is a great initiative , but also energy-saving lamps LED fluorescent energy saving than 1/ 4, which is a solid light source greater reforms. In addition , LED lamps also have other advantages, high quality of light , almost no radiation , typical of the green lighting ; reliable and durable, very low maintenance costs and so on. Because LED light source also has the above other solid unmatched features , 10 years after the LED lighting industry will be the mainstream light.

　　( 2 ) Safety and environmental protection : LED lamps , low voltage, mostly 1.4-3V; ordinary LED operating current of only 10mA, high brightness but also 1A. LED in the production process do not add the " Mercury " and does not need inflated , no glass shell , impact resistance , shock resistance , unbreakable , easy to transport , very green , known as the "green energy ."

　　( 3 ) Long life : LED lamp small size , light weight , the shell is epoxy encapsulated , not only can protect the internal chip , but also has the ability to light condenser . LED life generally in the 50,000-100,000 hours in between, because the LED is a semiconductor device , even frequent switching , it will not affect the service life. Currently the main use of home lighting is incandescent, fluorescent lamps and fluorescent lamps .

　　(4) Fast response : LED lighting frequency response of the injection lifetime of minority carriers related materials such as GaAs LED, the usually in the range of 1-10ns , the response frequency is about 16-160MHz , such a high frequency response of the video signal for display 6.5MHz is enough , and this is for video LED screen of the key factors .

　　Currently, LED lamps have reached the minimum response time is 1 microsecond , more than a few milliseconds in general , the response time of ordinary light is about 1 /100. It can be used in many high frequency environments , such as automotive brake lights or status lights , rear of the vehicle can shorten the braking time , thereby improving safety.

　　( 5 ) High luminous efficiency : incandescent, halogen light efficiency is 12-24lm / w ( lm / W ) , fluorescent light efficiency of 50-70lm / w, sodium lamp luminous efficiency of 90-140lm / w, most of the power into heat loss . The LED lamps light efficiency can be achieved through improved 50-200lm / w, and the light color is good , narrow spectrum , can be sent directly without filtering colored visible light.

　　( 6 ) LED luminaire strong point : light attenuation is much lower than conventional light sources .
