Kev nyuaj ntawm LED teeb vaj huam sib luag
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.
LED vaj huam sib luag teeb
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 hauv kev teeb pom kev zoo, 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 tus yuam sij rau kev lag luam LED. Nyob rau tib lub sijhawm, PN kev sib tshuam kub ntawm LED thiab cua sov ntawm lub plhaub yog 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.
