Peb core technologies ntawm LED vaj huam sib luag teeb
Kev ua haujlwm kho qhov muag ntawm LED vaj huam sib luag teeb feem ntau suav nrog kev ua haujlwm ntawm luminosity, spectrum thiab chromaticity. Raws li tus qauv kev lag luam tshiab "Semiconductor Light Emitting Diode Test Method", muaj cov luminous ncov wavelength, spectral radiation bandwidth, axial luminous siv lub kaum ntse ntse, luminous flux, radiant flux, luminous zog, chromaticity coordinates, muaj feem xyuam xim kub, xim purity thiab dominant wavelength, tsis xws li xim rendering Performance index. Rau cov LEDs dawb feem ntau siv hauv LED vaj huam sib luag teeb, xim kub, xim rendering Performance index thiab illuminance yog qhov tseem ceeb. Nws yog lub hom phiaj tseem ceeb ntawm lub teeb pom kev zoo thiab cov nyhuv, thaum xim purity thiab tseem ceeb wavelength feem ntau tsis tas yuav tsum tau.
Kev coj ua tseem ceeb hauv kev lag luam LED yog tias tom qab ntim cov chips LED los tsim lub teeb los yog lub teeb ci module, lub teeb faib yog nqa tawm thaum lub teeb tsim. Qhov no yog thawj txoj kev teeb pom kev zoo, vim tias cov teeb pom kev zoo ib txwm muaj 360 degree teeb. Yog tias koj xav coj lub teeb mus rau qhov kawg ntawm kev siv, Philips 'cov teeb pom kev zoo tam sim no yog qhov zoo tshaj plaws, thiab lub teeb poob kuj nce mus txog 40 feem pua. Txawm li cas los xij, qhov tsis zoo ntawm cov teeb pom kev siv los ntawm ntau lub tuam txhab tsim hluav taws xob hauv tsev LED yog thawj qhov tsis zoo ntawm cov nti lossis lub teeb ci, tsis yog lub hom phiaj kho qhov muag ntawm tag nrho lub teeb.
Yuav ua li cas txhawm rau txhim kho kev ua haujlwm ntawm lub teeb kom zoo? Lub ntiaj teb tshiab thev naus laus zis yog ua lub teeb faib rau ntawm pob chip, xa tawm lub teeb ntawm lub nti ib zaug, thiab hais kom muaj lub teeb pom kev loj, yog li lub teeb poob tsuas yog 5 feem pua -10 feem pua. Nrog rau kev txhim kho txuas ntxiv ntawm kev txawj ntse, lub teeb poob qis yuav qis dua thiab qis dua, thiab lub teeb pom kev zoo ntawm lub teeb ci yuav siab dua thiab siab dua. Tib lub teeb nrog lub teeb pom kev zoo li no tsis tas yuav tsum muaj lub teeb tis, thiab lub zog txheeb ze ntawm lub teeb yuav zoo dua qub, ua rau nws siv ntau dua hauv kev teeb pom kev zoo, tsim lub khw loj -scale khw. Yog li ntawd, tus neeg muag khoom zoo LED yog peb qhov kev xav tau ceev. Peb tsis tas yuav siv nyiaj ntau los kawm seb peb cov LEDs tau faib li cas, thiab peb tsis tas yuav siv sijhawm ntau thiab kev paub dhau los rau cov engineers siv software simulation. Txoj kev yooj yim yog Nws yog cia LED dawb lub teeb xa khoom los koom tes. Koj paub, yog tias peb cov engineers siv software los simulate, qhov tsim nyog ua yog cov tswv yim thiab tso tawm. Cov tswv yim yog cov ntshuam ntawm cov ntaub ntawv nyob rau hauv thaum ntxov, thiab cov zis yog qhov tshwm sim ntawm simulation, yog li cov ntaub ntawv nyob rau hauv thaum ntxov theem ntawm kev thov yuav tsum muaj tseeb thiab simulation ntawm lub back-kawg yuav tsum yog.
Thermal Properties (Kev tsim kho):
Lub zog luminous thiab lub zog ntawm LEDs rau teeb pom kev zoo yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm LED kev lag luam. Nyob rau tib lub sijhawm, PN hlws ris kub ntawm LED thiab cov cua kub dissipation ntawm lub casing yog qhov tseem ceeb tshwj xeeb. Qhov ntau dua qhov sib txawv ntawm PN hlws ris kub thiab lub teeb lub cev kub, qhov ntau dua qhov thermal kuj, thiab tom qab ntawd lub teeb lub zog hloov mus rau hauv lub zog hluav taws xob thiab siv tsis muaj nuj nqis, uas yuav ua rau LED puas tsuaj rau qhov mob hnyav. Ib tug zoo structural engineer tsis tau tsuas yog yuav tsum tau xav txog cov qauv ntawm lub teeb thiab thermal kuj ntawm lub LED, tab sis kuj seb cov duab ntawm lub teeb yog tsim nyog, fashionable thiab tshiab, thiab ntawm chav kawm, kev cia siab, kev ruaj ntseg thiab practicability. Xav txog ntawm tus neeg siv qhov kev xav, thiab xav txog cov khoom los ntawm tus neeg siv qhov kev xav.
Cov cuab yeej siv niaj hnub no feem ntau yog siv aluminium substrates rau ntim. Muaj cov kev tsis sib haum xeeb nyob rau hauv cov cua kub dissipation thiab kho qhov muag hloov lub zog ntawm txhuas substrates, uas tsis tuaj yeem tswj tau qhov kub thiab txias thiab ruaj khov ua kom siab siab - lub zog lub teeb tso zis. Qhov siab dua nws yog, qhov loj dua qhov yuav tsum tau ntawm thaj tsam ntawm aluminium substrate yuav yog, uas yuav nce tus nqi thiab siv ntim, uas yog qhov tsis yooj yim heev. Yog li yuav ua li cas kom tau tawm ntawm qhov kev nkag siab yuam kev no thiab nrhiav txoj hauv kev tshiab yog qhov tshiab qhov chaw txawj ntse. Raws li kev tswj hwm tus nqi qis thiab tsis muaj cua sov dissipation, kev siv cov thermal conductivity nruab nrab, los ntawm cov qauv tshiab tag nrho ntawm cov khoom siv / teeb, txo cov thermal tsis kam thiab hlws ris kub ntawm PN hlws ris, kom PN hlws ris ua haujlwm nyob rau hauv qhov tso cai ua haujlwm kub. thiab tuav ib tug loj tus naj npawb ntawm photon tso zis, thiab nws ob peb thov yog raws li nram no:
(1) Ultra- cov khoom siv thermal tsis tshua muaj, tag nrho cov txheej txheem thev naus laus zis rau cov cua kub sai sai;
(2) High thermal conductivity thiab tiv thaiv -UV ntim cov txuj ci;
(3) Siv cov txuj ci tsim kho kev ntxhov siab ib puag ncig tsawg;
(4) Tag nrho cov thermal tsis kam< 20k/w,="" junction="" temperature="">< 80="">
(5) Kev khiav hauj lwm kub ntawm LED teeb qhov chaw teeb pom kev zoo yuav tsum tau tswj hauv qab 65 degree.
Hluav taws xob cov khoom (electronics):
Yog hais tias lub teeb pom kev zoo yog piv rau ib tug ntxhais, ces lub teeb tis yog nws lub cev sab hauv, tus qauv yog nws cov tsos, thiab lub electron yog nws lub siab. Ib tug neeg tsis muaj lub neej tsis muaj lub siab, thiab lub teeb tsis tuaj yeem ua lub zog tsis muaj hluav taws xob. Lub zog tsav tsheb zoo tuaj yeem txiav txim siab lub neej ntawm cov khoom. Cov kev qhia tshwj xeeb hauv hluav taws xob thiab cov tsis muaj feem ntau yog qhov nyuaj dua li cov qauv, thiab kev tsim kho lub zog thaum ntxov kuj tseem loj heev. Cov qauv tam sim no thiab kev hloov tshiab ntawm kev txawj ntse tau hloov pauv txhua hnub, thiab cov engineers yuav tsum siv ntau lub zog los kawm, nqus, sib txawv, thiab siv cov txuj ci tshiab. Kev npaj ua ntej - kev npaj hluav taws xob yog siv nyob rau hauv nruab nrab - lub sij hawm, thiab tag nrho cov txheej txheem ntawm kev tsim nyob rau hauv lub tom ntej theem yuav tsum tau tsim cov ntaub ntawv thiab cov ntaub ntawv, uas kuj yog ib tug tedious ua hauj lwm nyob rau hauv kev npaj. Piv txwv li: ib qho kev npaj ua ntej hauv kev npaj cov khoom siv hluav taws xob, kev qhia txog cov khoom, cov hauv paus ntsiab lus, cov qauv kev nyab xeeb, kev cia siab ntawm hluav taws xob, kev xav tau, kev ntsuam xyuas cov khoom siv raw, cov qauv kev sim, thiab lwm yam., tag nrho cov ntaub ntawv kaw lus.
