Why choose LED lights including the high power LED flood light
( A ) Energy conservation : the spectrum of LED especially the high power LED flood light almost concentrates in the visible light spectrum, the luminous efficiency is up to 80-90%. We have compared the LED and incandescent , spiral energy saving lamps and T5 trichromatic fluorescent，the results showed that: the light efficiency of ordinary incandescent is 12lm / w, life expectancy is less than 2000 hours , the luminous efficiency of spiral energy saving lamp is 60lm / w, less than 8000 hours life , T5 fluorescent lamps is 96Alm / w, life is about 10,000 hours, and white LED such as the high power LED flood light whose diameter is 5 mm is 20-28lm / w, life can be more than 100,000 hours. It was also predicted that the future of the LED lifetime will be infinite.
Most people believe what a great initiative is that energy-saving lamps can save more 1 /5 energy , but high power LED flood light can save more than 1/ 10 that energy-saving lamps, which is the greater reforms for the solid light source. In addition, LED also has other advantages , the high power LED flood light and other LED light is of highly quality light, almost no radiation , which is typically the green lighting ; reliable and durable, very low maintenance costs and so on. It is because that LED light source also has the above features other solid unmatched , the high power LED flood light and other LED light will be the mainstream of the commercial and household lighting industry 10 years later.
( B) safety and environmental protection : LED ‘s operating voltage is low, mostly 1.4-3V; ordinary LED operating current is only 10mA, high brightness is just 1A. LED do not add the ” Mercury ” during the production process and does not need inflated , take the high power LED flood light for example，it has no glass shell and is known as impact resistance , shock resistance , unbreakable , easy to transport , very green , known as the “green energy .”
( C ) Long life : LED is of small size , light weight , the shell is epoxy encapsulated , which can not only protect the internal chip , but also has the ability to transmit and condense the light . LED life generally between the 20,000-30,000 hours, because the LED is a semiconductor device , even frequent switching , the high power LED flood light and other LED light will not affect the service life. the main use of home lighting is currently incandescent, fluorescent lamps and fluorescent lamps .
(D ) fast response : fτ that is the response frequency of LED is related to the τmc materials which is the lifetime of minority carriers injected such as LED that is the source of LED light including the high power LED flood light made from GaAs, the τmc is usually between the range of 1-10ns , the response frequency of LED is about 16-160MHz, such a high frequency response is enough for the video signal displaying 6.5MHz , and this is the key factors for achieving video LED screen of .
Currently, the minimum response time of LED has reached is 1 microsecond , more than a few milliseconds in general , which is about 1 /100 of the response time of ordinary light. It can be used in many high frequency environments , such as automotive brake lights or status lights , which can shorten the braking time between of the rear vehicle, thereby improving safety.Browsing http://www.lead-lighting.com/products/sid125-1.htm for more about the characters and used of affordable but pretty competitive high power LED flood light.
