7、ation hold can manifestation variety of numeral, writing, sketch picture， Can not only used for an indoor environment but also used for outdoors environment, have to cast shadow an instrument, television wall, LCD manifestation to hold the advantage that cant compare to. The reason that, the LED be

8、extensively valued but get quick development, is with it have of advantage inseparable. These advantages summarize BE， Bright degree Gao, work the electric voltage be low, achievement consume small and small scaled turn, life span long, bear pound at and function stability. The LED development foreg

9、round is extremely vast, currently just toward the higher and bright degree, higher bear weather, higherly give out light density and higherly give out light even, the credibility, whole color turn a direction development. the LED manifestation hold a development process 30 year review1970s at the e

10、arliest stage of GaP, GaAsP together quality knot red, Huang, green low give out light the LED of efficiency a beginning already application at the indicator, numeral and writing manifestation .From now on the LED start get into a variety application realm and include astronautics, airplane, car, in

11、dustry application, correspondence, consume type product etc., all over each section of national economy and thousand 10000.To 1996 LED is in the whole world of sale sum already arrive several USD 1,000,000,000.Though the LED has been be subjected to a color and give out light the restriction of eff

12、iciency over several years, have a longevity life because of the GaP and the GaAsP LED, Gao credibility, work the electric current be small, can and TTL, CMOS numeral electric circuit and permit many advantage of etc. as a result has been be subjected to the green Mi of user. 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

29、und at and vibrate. 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
