Recent decade, Gao Lian
13、g4 Du4 turn, whole colors turn has been being LED material and spare part craft technique research of front follow a topic. The extremely high and bright degree(UHB) is that give out light strength to attain or more than 100 mcd LED, call hole again virtuous pull(cd) class LED. Gao Liang4 Du4 the A1
14、 GaInP and InGaN LED develop to make progress very quick, now already arrive normal regulations material GaA1 As, GaAsP, GaP impossible attain of function level.1991 Toshiba in Japan company and the United States the HP company develop into the InGaA1 P 620 nm an orange and extremely high and bright
15、 degree LED, 1992 the InGaA1 p 590 nm yellow extremely high and bright degree the LED be practical to turn At the same year, Toshiba company develop the InGaA1 P 573 nm Huang green an extremely high and bright degree LED, method to light as strong as 2 cd.1994 Japan day the second company develop in
16、to InGaN450 nm blue(green) color extremely high and bright degree LED. Go to this, color manifestation three Ji colors need be red, green, blue and orange, Huang variety the LED of the color all come to a hole virtuous pull give out light of class strength, realization the extremely high and bright
17、degree turn, the whole color turn and make to give out light tube of outdoor whole color manifestation become reality. Our country development LED start in 70s, the industry appear in 80s.There is around more than 100 business enterprise in whole country, 95% factory house all be engaged in behind w
18、ay pack produce, need tube Xin almost all from the abroad import. Pass the technique of a few five years plan reformation, the technique offend pass and usher in abroad forerunner equipments and parts of key technique, make our country LED of produce the technique have already step forward into one
19、step. Two, extremely high and bright degree LED function: The extremely high and bright degree red A1 GaAsLED and GaAsP-GaP LED compare, have to higherly give out light an efficiency, the flow of transparent Chen low(TS) A1 GaAs LED(640 nm) clear efficiency already close 10 lm/w, ratio the red GaAsP
20、-GaP LED big 1000%.Color and GaAsP-GaP that the extremely high and bright degree InGaAlP LED provide LED homology include， academy blue(560 nm), shallow academy blue(570 nm), yellow(585 nm), shallow Huang(590 nm), orange(605 nm) and pink(625 nm deep red.(640 nm)The transparent Chen bottom A1 GaInP L
21、ED give out light an efficiency and the other LED structure and white Chi light source of comparison, the InGaAlP LED absorb the flow of Chen bottom(AS) clear efficiency as 101 m/w, the transparent Chen bottom(TS) want to be 10 s in height than the GaAsP-GaP flow of LED clear efficiency within the s
22、cope of the wave-length of 590 626 nm for the 201 m/w 2000%；In 560 s 570 wave-length scopes ratio GaAsP-GaP LED Gao Chus 2 s 400%.The extremely high and bright degree InGaN LED provided an orchid color light and green light, its wave-length scope orchid color is 450 480 nm, orchid green is 500 nm, g
23、reen is 520 nm， It flow the clear efficiency as 3 151 m/ws. Extremely high and bright degree LED currently flow a clear efficiency have already exceeded to take the incandescent lamp of color filter, can replace the power incandescent lamp within 1 w, and use a LED array can replace the power incand
24、escent lamp within 150 w. For many application, all of incandescent lamps be an adoption color filter to get red, orange, green and orchid color, but use an extremely high and bright degree LED can then get homology of color. The extremely high and bright degree of the material and InGaN material ma
25、nufacturing of the recent years AlGaInP LED many extremely high and bright degree LED chip combination together, need not color filter also ability get various color. Include red, orange, Huang, green and blue, currently its giving out light an efficiency all have already exceeded an incandescent la
26、mp, is connecting toward the fluorescent lamp near. Give out light a bright degree Gao have already canned satisfy outdoors at the 1000 mcd all-weather, whole color manifestation of demand, use LED color big screen can performance the sky and ocean, realization 3D animation. The new generation red,
27、green and blue and extremely high and bright degree LED come to an unprecedented function. Three, extremely high and bright degree LED application: 1.information indicator Car signal designation， car indicators exterior in cars being main be a turn signal, tail lamp and brake light， Main is various
28、appearance in the inner part of car of illuminate and manifestation. The extremely high and bright degree LED used for car indicator and the incandescent lamp of tradition to compare to have many advantage, in the car industry have extensive of market .The LED can experience a stronger machine to po

Average work life span MTBF ratio incandescent lamp bubble GaoChu Ji3 quantity class, far farGao Chus car of work life span, so flow bottom work, typical model of drive electric current an incandescent lamp to only at least have 12 red, yellow, blue green signal beacon. 2.great s
30、creen manifestation Great screen manifestation is extremely high and bright degree LED application of another one huge market, include， color and whole color of the monochrome, double of the sketch, writing, numeral manifestation. Tradition of the big screen have a source manifestation general adopt
31、ion incandescent lamp, fiber optic, cathode ray tube etc.， Have no source manifestation general adoption turn over the method of card .Form 3 listed a few kinds manifestation of function comparison. The LED manifestation once had been be subjected to LED function and the restriction of the color .No
32、w the extremely high and bright degree AlGaInP, TS-AlGaAs, InGaN LED have already can provide brightness of red, Huang, various green and blue color, can complete satisfy realization whole color big screen manifestation of request. LED manifestation hold can assemble into various structure according
33、 to the pixel size, figurine vegetable diameter general small at the 5 mm, monochrome manifestation of each pixel use a LED light of T-1(3/4), double color manifestation of each pixel is double the LED light of T-1(3/4) of the color, whole color manifestation demand 3 T-1 be red, green, blue light, perhaps assemble much aer LED light of T-1(3/4) of chip be a pixel. The big pixel then pass pair of many T-1(3/4) red, green, the blue LED light combination together constitute of.UseInGaN(480 nm) blue, InGaNs(515
