Peb lub thev naus laus zis tseem ceeb ntawm LED vaj huam sib luag teeb
Kev ua haujlwm zoo (kev faib lub teeb): Kev ua haujlwm kho qhov muag ntawm LED vaj huam sib luag teeb feem ntau cuam tshuam nrog kev ua tau zoo raws li qhov ci ntsa iab, qhov pom thiab chromaticity. Raws li cov txheej txheem kev lag luam tshiab tshaj plaws" Txoj Kev Xeem rau Semiconductor Lub Teeb-Emitting Diodes&";, feem ntau yog qhov ci ntsa iab siab tshaj plaws nthwv dej, spectral hluav taws xob bandwidth, axial luminous siv lub kaum ntse ntse, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, sib txheeb xim kub, xim purity thiab tseem ceeb wavelength, Parameters xws li xim rendering Performance index. Cov xim kub, xim ntsuas qhov ntsuas thiab qhov pom kev ntawm cov xim dawb LED feem ntau siv hauv LED teeb vaj huam sib luag yog qhov tshwj xeeb. Nws yog qhov taw qhia tseem ceeb ntawm cov teeb pom kev zoo thiab cov txiaj ntsig, tab sis xim dawb huv thiab qhov tseem ceeb nthwv dej feem ntau tsis xav tau.
Kev coj ua tseem ceeb hauv kev lag luam LED yog txhawm rau txhawm rau txhawm rau teeb tsa lub teeb los yog lub teeb pom kev zoo, thiab tom qab ntawd faib lub teeb thaum nws ua rau lub teeb. Qhov no yog thawj txoj kev teeb pom kev ib txwm muaj, vim tias lub teeb pom kev ib txwm tso tawm 360 ° lub teeb. Yog tias koj xav coj lub teeb mus rau daim ntawv thov, tam sim no Philips tsoos teeb yog qhov zoo tshaj plaws, thiab lub teeb poob tuaj yeem ncav cuag 40%. Cov teeb pom kev zoo ntawm cov teeb siv los ntawm ntau ntawm peb cov tuam txhab LED hauv qab cov lag luam yog qhov ua tau zoo ntawm cov nti lossis lub teeb ci, tsis yog qhov ntsuas qhov ntsuas qhov ntsuas ntawm tag nrho cov teeb.
Yuav ua li cas txhawm rau txhim kho lub teeb pom kev zoo, lub ntiaj teb' thev naus laus zis tshiab tshaj plaws yog ua kom pom kev faib tawm ntawm lub pob ntim, xa tawm lub teeb ntawm lub nti ib zaug, thiab tswj lub teeb pom kev ntau tshaj, kom lub teeb ci qhov poob tsuas yog 5%-10%. Nrog kev txhim kho thev naus laus zis tas mus li, lub teeb pom kev poob qis dua thiab qis dua, thiab kev ua haujlwm ntawm lub teeb pom kev zoo yuav siab dua thiab siab dua. Cov teeb uas muaj cov teeb pom kev zoo no tsis tas yuav tsum teeb lub teeb, thiab cov teeb pom kev zoo ntawm cov txheeb ze yuav zoo dua qub, ua rau lawv siv ntau dua hauv kev ua haujlwm teeb pom kev zoo, tsim kev lag luam ntau. Yog li ntawd, cov khoom lag luam LED zoo yog peb qhov tseem ceeb tshaj plaws. Peb tsis tas yuav siv tus nqi siab los kawm yuav ua li cas peb cov LEDs faib lub teeb, thiab peb tsis tas yuav siv sijhawm ntau thiab kev paub rau cov kws tsim txuj ci los siv software simulation. Txoj hauv kev yooj yim tshaj plaws yog Cia lub LED dawb lub teeb muab kev koom tes. Koj paub, yog tias peb cov kws tsim txuj ci siv software los ua piv txwv, tom qab ntawv qhov tsim nyog ua yog tawm tswv yim thiab tso tawm. Cov tswv yim yog cov ntaub ntawv yav dhau los ntshuam, thiab cov txiaj ntsig yog qhov tshwm sim simulation, yog li cov ntaub ntawv yav dhau los yuav tsum muaj qhov tseeb thiab kev sim tom qab kawg tuaj yeem raug.
Kev ua kom sov (qauv): Lub teeb pom kev zoo thiab lub zog hluav taws xob ntawm LEDs rau teeb pom kev zoo yog ib qho ntawm cov yuam sij rau kev lag luam LED. Nyob rau tib lub sijhawm, PN kev sib tshuam kub ntawm LED thiab cua sov ua kom tawg ntawm lub plhaub tshwm los ua qhov tshwj xeeb. Qhov sib txawv ntau dua ntawm PN qhov sib txawv ntawm qhov kub thiab lub teeb lub cev kub, ntau dua cov cua sov ua haujlwm, thiab tom qab ntawd lub teeb ci tau hloov pauv mus ua cua sov thiab siv tsis tau. Hauv cov xwm txheej hnyav, LED puas. Tus kws tsim qauv zoo yuav tsum tsis yog tsuas yog xav txog tus qauv ntawm lub luminaire thiab kev tiv thaiv cua sov ntawm LED, tab sis kuj tseem pom tias cov teeb pom kev zoo tsim nyog, zam, tshiab, thiab tau kawg ntseeg tau, tswj tau, thiab ua tau zoo. Txhawm rau xav los ntawm kev xav ntawm tus neeg siv, tab sis kuj xav txog cov khoom los ntawm kev xav ntawm tus neeg siv.
Cov thev naus laus zis niaj hnub no yog siv cov txhuas txheej rau ntim. Cov cua sov ua kom sov thiab ua kom pom kev hloov pauv ntawm aluminium substrate ntim muaj cov txuj ci tseem ceeb, uas tsis tuaj yeem tswj hwm qhov sib txuas ntawm qhov kub thiab ruaj khov tswj lub zog hluav taws xob lub zog loj, thiab daim ntawv thov yuav yog vim lub teeb pom kev zoo dua ntawm lub nti. , Qhov loj dua thaj tsam ntawm aluminium substrate xav tau yuav nce tus nqi thiab daim ntawv thov ntim, uas yog qhov tsis yooj yim heev. Yog li ntawd, yuav ua li cas txhawm rau tawm ntawm qhov kev nkag siab yuam kev no thiab tsim txoj hauv kev tshiab yog lub hauv paus tseem ceeb ntawm cov thev naus laus zis tshiab. Ntawm qhov chaw tswj hwm tus nqi qis thiab tsis muaj cua sov ua kom sov, siv cov khoom siv hluav taws xob ua kom sov siab, dhau los ntawm cov cuab yeej tshiab/teeb pom kev zoo tag nrho, txo cov cua sov ua haujlwm, txo qis PN kev sib tshuam kub, ua rau PN hlws ris ua haujlwm nyob rau hauv qhov kev tso cai ua haujlwm kub thiab tswj hwm ntau npaum li cas ntawm photons Qhov tsawg kawg nkaus xav tau rau cov zis yog raws li hauv qab no:
(1) Ultra-low cov khoom ua kom tsis muaj cua sov, ua kom sov sai ua kom tawg tag nrho cov qauv thev naus laus zis;
(2) Kev ua kom muaj cua sov zoo, tiv taus UV ntim tshuab;
(3) Daim ntawv thov kev siv thev naus laus zis thev naus laus zis qis;
(4) Zuag qhia tag nrho cov cua sov ua haujlwm< 20k/w,="" qhov="" kub="" thiab="" txias="" sib="">< 80="">
(5) Kev ua haujlwm kub ntawm LED teeb pom kev zoo teeb pom kev zoo tswj tau qis dua 65 ° C.
Cov khoom siv hluav taws xob (khoom siv hluav taws xob): Yog tias koj piv cov teeb pom kev zoo rau tus ntxhais hluas, tom qab ntawd lub teeb faib yog nws lub ntsiab lus, tus qauv yog nws qhov tsos, thiab hluav taws xob yog nws lub siab. (Nws ib txwm yog cov zoo nkauj thiab zam zoo nkauj uas nyiam tib neeg' kev saib xyuas, thiab tib yam muaj tseeb rau cov khoom lag luam). Ib tug neeg tsis muaj lub neej tsis muaj lub siab, thiab lub teeb tsis tuaj yeem yog lub zog hluav taws xob yam tsis muaj hluav taws xob. Lub zog tsav tsheb zoo tuaj yeem txiav txim siab lub neej ntawm cov khoom. Cov txheej txheem hluav taws xob thiab cov txheej txheem feem ntau nyuaj dua li tus qauv, thiab kev tshawb fawb thawj zaug thiab kev txhim kho kuj tseem loj dua. Cov txheej txheem thev naus laus zis tam sim no thiab hloov tshiab tau hloov pauv nrog txhua hnub dhau los. Cov kws tsim txuj ci yuav tsum tau siv lub zog ntau los kawm, nqus, decompose, thiab siv cov thev naus laus zis tshiab. Tag nrho cov txheej txheem ntawm kev tsim hluav taws xob' kev npaj thaum ntxov, kev ua haujlwm ib nrab sijhawm, thiab tom qab molding yuav tsum tau muab teev tseg thiab tsim cov ntaub ntawv. Qhov no kuj yog qhov nyuaj tshaj plaws hauv kev tsim. Piv txwv li: kev npaj ua ntej rau kev tsim khoom siv hluav taws xob, cov khoom lag luam, cov txheej txheem kev qhia tshwj xeeb, kev nyab xeeb tshwj xeeb hauv paus, kev ua tau zoo ntawm hluav taws xob, kev xav tau ntawm cov txheej txheem, kev tshuaj xyuas cov khoom nyoos, ntsuas cov txheej txheem, thiab lwm yam yuav tsum tau tsim rau hauv cov ntaub ntawv kaw lus.
BENWEI teeb pom kev zoo yog tag nrho ntawm cov lus dab neeg hauv thaj tsam ntawm LED tsav lub zog hluav taws xob. Tawm ntawm qhov kev nkag siab ntawm kev lag luam LED, Yang Chao, lub taub hau ntawm BENWEI teeb pom kev zoo, coj nws pab neeg los tsim cov khoom siv hluav taws xob LED hauv xyoo 2008. Niaj hnub no, BENWEI teeb pom kev zoo' ntiaj teb-kev siv tshuab tau coj tus qauv ntawm txawj ntse tsav tsheb ntawm txoj kev teeb LED, thiab thov kom muab cov teeb LED txoj kev teeb nrog cov txhim khu kev ntseeg tshaj plaws tsav kev daws teeb meem. Nov yog lwm qhov piv txwv ntawm kev coj ua tswv yim.
