It is widely applied in display screen, generates good economic benefit and social benefit.With 12 inches of red traffic light
Exemplified by, it was to use the long-life originally in the U.S., 140 watts of incandescent lamps of low luminous efficacy are as light source, and it produces 2000 lumens
White light.After Red lightscreening plate, the feux rouges of light loss 90%, only remaining 200 lumens.And in newly-designed lamp, Lumileds is public
Department employs 18 red LED light sources, including circuit loss, 14 watts of power consumption altogether, you can produce same light efficiency.Automobile is believed
Signal lamp is also the key areas of LED/light source application.
For general illumination, light source of the people with greater need for white.The LED emitted white light for 1998 is succeeded in developing.It is this
LED is by GaN chips and yttrium-aluminium-garnet（YAG）It is packaged together and makes.GaN chip blue light-emittings（λ p=465nm, Wd=
30nm）, the YAG fluorescent powder containing Ce3+ that high temperature sintering is made sends sodium yellow after being excited by this blue light and penetrates, peak value 550nLED lamps
m.Blue-ray LED substrate is arranged in bowl-type reflection cavity, covers to be mixed with YAG thin resin layer, about 200-500nm.LED substrates
The blue light components sent are absorbed by fluorescent material, and another part blue light is mixed with the gold-tinted that fluorescent material is sent, and can obtain white light.
For InGaN/YAG White LEDs, by changing the chemical composition of YAG fluorescent powder and the thickness of regulation phosphor powder layer,
Colour temperature 3500-10000K assorted white light can be obtained.This method that white light is obtained by blue-ray LED, simple structure, cost
Cheap, technology maturity is high, therefore with most.
Due to the high directivity of LED light, light is difficult to rearwardly spread, and light distribution angle is not big enough, in order to meet illumination
Various demands are, it is necessary to increase lighting angle.
