Txheej xwm txheej xwm ntawm LED pom npo

LED zaub yog ib lub ntsiab lus teb ntawm LED. Nws tau tsim sai heev nyob rau hauv xyoo tas los. Lub teeb emitting diodes yog dav siv. Lawv txais tos los ntawm hluav taws xob engineers thiab cov neeg tshawb nrhiav vim lawv tsis ua hauj lwm voltage, tsawg zog noj, nplua nuj xim thiab tsawg tus nqi. Hauv cov theem thaum ntxov, qhov zoo ntawm cov khoom siv luminous tsawg tsawg, thiab qhov siv lub teeb yog feem ntau ntau rau dozens ntawm MCD. Nws yog tsim rau siv hauv tsev thaum nyob hauv tsev, thiab siv cov cuab yeej hluav taws xob, ntsuas, ntsuas, khoom siv sib txuas lus, microcomputers thiab cov khoom ua si. Cov teebmeem ntawm daim ntawv thov kev siv technology, cov khoom siv tshiab ntawm lub sijhawm tshiab, LED Christmas teeb yog nrov, vim tias cov duab zoo nkauj tshiab, hom teeb liab kub thiab cov xim kub lub teeb, Zhulian qhov rais teeb, thiab xim nplua nuj, tsis txhoj puab, tsis tshua muaj siab, tsis ntev los no hauv Hongkong nyob rau sab Asia sab hnub tuaj muaj zog, muaj neeg feem ntau zoo siab tos txais, thiab tab tom yuav los hloov qhov teebmeem uas muaj teebmeem Christmas lub khw. Raws li cov khoom siv, lub teeb emitting diode hom AD11 qhia tias kev siv cov teeb nyob rau hauv lub hwjchim, muaj peb xim liab daj thiab ntsuab, lub chaw muag khoom hauv Jiangsu, lub tuam txhab cov muag txhua xyoo tau tshaj 10M toj xyoo (200 ~ 300) , MLED nti, thiab lub peev xwm rau kev nthuav dav ua lag luam. Raws li ib qho ntawm lub teeb-emitting ntshiab cov lus qhia, lub neej ntev, tsawg zog noj thiab lwm yam nta, nrov heev nrog cov neeg siv, thiab sai tau txhua tus hloov cov npuas hom AD11. Hauv ntej, cov kev lag luam uas muaj teeb pom kev lag luam hauv kev lag luam yuav tsis tsuas yog nrog txoj kev loj hlob ntawm cov khoom qub los txhim kho daim ntawv thov kev pab, tab sis kuj yog cov kev siv tshiab los qhib kev ua lag luam.

Advanced teeb tsa emitting diode

Nrog rau kev tsim cov ntaub ntawv tshiab thiab kev lag luam nyob rau hauv kev lag luam ntawm kev lag luam, txij li thaum xyoo 1994 pom cov ntaub ntawv pom tshiab hauv InGaAlP thiab InGaN raws li lub ntsiab, kom ua tau zoo siab, xim, thiab khoob siv technology, khoom muag, coj cov kev lag luam ntau dua. Cov khoom siv no yog tsim los ntawm kev siv ntawm daim ntawv thov LED rau sab hauv tsev sab nrauv, tuaj yeem pom tseeb hauv cov teeb meem tshav kub muaj zog, kev ua kom pom zoo, kev siv lub teeb ntau dua 1000mcd, tib lub sij hawm kom tau raws li cov xim xim thiab cov khoom siv kom tsis muaj zog. Cov kev lag luam uas muaj siab tshaj plaws no muaj xws li hom nram qab no.

(1) Blue and green light-emitting diodes, cov khoom xiav LED yog silicon carbide (Suc), gallium nitride (GaN) thiab indium nitrogen gallium (InGaN) peb cov khoom siv nyiaj. Lub ncov ntawm lub teeb siab ntawm lub teeb ntsuab yog 520nm, thiab lub cev zoo li 5000mcd. Rau lub hauv paus ntawm xiav lub teeb ntawm kev hloov ntawm cov khoom siv fluorescent ntxiv ob peb hom kab hauv cov chip pob yog dawb, dawb LED yog qhov zoo tshaj plaws rau lwm qhov teeb meem me me roj teeb, tab sis tus nqi kim tshaj qhov teeb, tab sis tsis yooj yim tawg, ntau zog , Thaum yuav luag tsis muaj cua sov, nruam teeb pom kev zoo rau 10 xyoo, cov khoom tsim nyob rau hauv Nyiv, Lub teb chaws Yelemees, Tebchaws Asmeskas thiab Taiwan thiab lwm lub koom haum ua lag luam nto moo thiab kev lag luam.

(2) Ib hom tshiab ntawm plaub qhov kev coj ua tau tsim nyob rau xyoo 80s. GaAlAs khoom yog tsim rau hauv liab liab. Ua ntej tshaj, qhov ultra siab ci yuav tsum tau ua, thiab siv qhov luminous ntau tshaj 1000mcd. 90s zoo tsim InGaAlP plaub qhov khoom, ua cov khoom ua tau yog xim liab, txiv kab ntxwv, daj, plaub hau plaub hau xim, kev ua haujlwm siab zoo, thiab kev ua haujlwm siab kub zoo heev, zoo rau cov khoom siv sab nraum zoov.

(3) LED thiab lub zog ntawm ntau yam tshiab coj no pawg LED nti, khoom siv, cov khoom yuav ua tau rau hauv ib lub teeb emitting module, siv LED nti nti pawg ntawm ntau xim teeb, xim liab, ntsuab thiab xiav lub teeb nyob rau xim tsim ntawm panchromatic, nrab mus rau ntawm lub teeb dawb. Qhov tshwm sim ntawm cov kev pabcuam tshiab no tau nthuav txog daim teb ntawm cov ntawv thov LED. Thawj yog qhov teeb meem ntawm cov tsheb khiav lub teeb rau daim ntawv thov, nrog kev poob siab thiab kev ua hauj lwm, kev kub ceev, lub zog ntawm kev txuag thiab lub neej ntev; ua raws li daim ntawv thov kev tsav tsheb, pib thaum xyoo 1987, Tuam Tshoj pib nce siab nyob rau hauv lub tsheb nres teeb, LED vim muaj kev yoo mov, tuaj yeem ceeb toom tus tsav tsheb, txo qhov kev sib tsoo kev sib tsoo. Nyob rau hauv lub teb chaws tsim, kev siv ntawm cov hauv paus nruab nrab ntawm tsheb nres nres nres lub teeb tau dhau los ua tus qauv ntawm lub tsheb, lub tuam txhab United States HP launched hauv 1996 LED tsheb taillight module yuav tsum arbitrarily ua ke rau ntau hom taillights.

LED kev ua lag luam

LED yog ib qho hluav taws xob txuas hluav taws xob nrog ceev ceev hauv xyoo tsis ntev los no, nws muaj qhov zoo ntawm kev loj me me, lub cev nyhav, qis zog, tsis tshua muaj siab, kev ci ntsa ci thiab kev kub ceev yog ceev, yooj yim mus use thiab cov transistor thiab cov kev sib tshuam pob, yuav siv tau nyob rau hauv ntau lub teb, yog li nws yog nrov heev nyob rau hauv lub ntiaj teb no kev lag luam. LCD tau siv ntau hauv tshuab computer. High brightness liab teeb (GaAs thiab GaAsP) thiab daj teeb (InAlGaP) lub teeb emitting diode (LED) tau huab hwm coj, ntev ntev vim qhov tsis muaj siab ci xiav thiab ntsuab lub teeb los qhia cov nplua nuj xim, nyob rau hauv xyoo tas los , qaim siab xiav thiab ntsuab teeb-emitting diode tshuab tau ua kom tau zoo, thiab tsis tu ncua txhim kho khoom zoo, credit qiv rau LED luster. Tam sim no, nyob rau hauv lub ntiaj teb LED kev lag luam, xiav, ntsuab, dawb LED yog txoj kev ua ib qho teeb meem ntawm tripartite kev sib txeeb kev sib hloov, ua qhov feem ntau muaj peev xwm rau txoj kev loj hlob ntawm cov khoom LED.

Suav teb LED tawg

Nyob rau tam sim no peb lub teb chaws dav ntsuab siab thiab ntshiab liab LED muaj peev xwm ua tiav cov kev lag luam, Lub Teb Chaws Centre rau optoelectronic technology, Tuam Tshoj yog koom nyob rau hauv III ~ V semiconductor quantum zoo qauv raws li ib tiam tshiab ntawm optoelectronic li kev tshawb nrhiav thiab kev tsim kho, dais National 863 qhov project "xiav LED tshuab kev tshawb fawb thiab kev lag luam" hauv Suav; cov pab pawg coob thiab cov koom haum tshawb fawb, yuav yog thawj qhov ntawm cov cim ntawm cov cim thib peb hauv Suav teb (GaN) yuav siv los tsim cov LED, ntsuab LED thiab dawb LED industrialization ntawm kev tshawb fawb.

Tuam Tshoj txoj kev lag luam nyob hauv Taiwan yog qhov muaj siab heev. Nws yog qhov thib peb nyob rau hauv lub ntiaj teb no ua ntej thaum ntxov li 90s ntawm lub xyoo pua xeem. Tam sim no, Taiwan LED khoom lag luam sib qhia tau mus txog 28%, ntau tshaj li Asmeskas, qhov thib ob hauv lub ntiaj teb ua lag luam LED, tshaj li 80% ntawm cov khoom muag, mas muag rau South Kauslim, Nyiv, Tebchaws Asmeskas thiab Tebchaws Europe thiab lwm yam chaw. Tam sim no, LED kev lag luam nyob hauv Taiwan yog tsim los ntawm tag nrho cov xim, siab ci thiab loj teev.

Nyob rau hauv xyoo tas los no, lub ntsiab lus tswj kev lag luam ntawm LED zaub nrog loj teev kev sib cog ua ke (VLSI) kev loj hlob thiab ua kom zoo dua, EPLD, DSP thiab FPGA tau siv dav, qee cov tuam txhab tsim cov kev tswj tshwj xeeb ntawm cov tswj LED. Piv nrog LCD, PDP thiab LED zaub zoo xws li cov vaj huam sib luag cov khoom muag zaub, cov khoom siv nrog cov khoom noj uas tsis tshua muaj siab, kev ua haujlwm ntev, tsis muaj zog thiab tsis tshua muaj nqi, yog li nws muaj zog ua lag luam competitiveness ntau cov tswv yim, .
