Kev ua haujlwm kho qhov muag (lub teeb faib): Kev ua haujlwm kho qhov muag ntawmLED vaj huam sib luag teebFeem ntau suav nrog cov kev xav tau ntawm kev ua haujlwm ntawm luminosity, spectrum thiab chromaticity.Raws li qhov tseeb kev lag luam tus qauv "Semiconductor LED Test Method", feem ntau illuminating ncov wavelength, spectral radiance bandwidth, axial illuminance siv lub kaum ntse ntse, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated xim kub, xim purity thiab dominant waveleng. , Xim rendering Performance index thiab lwm yam tsis.LED vaj huam sib luag teeb feem ntau siv cov LEDs dawb, xim kub, xim rendering Performance index thiab illuminance yog ib qho tseem ceeb, nws yog ib qho tseem ceeb qhia txog lub teeb pom kev zoo thiab cov nyhuv, thiab xim purity thiab dominant wavelength feem ntau tsis tas yuav tsum tau.

Thermal kev ua tau zoo (cov qauv): LED luminous efficiency thiab fais fab mov rau teeb pom kev zoo yog ib qho ntawm cov tseem ceeb hauv kev lag luam LED.Nyob rau tib lub sijhawm, PN hlws ris qhov kub thiab txias ntawm LED thiab qhov teeb meem kub dissipation ntawm lub tsev yog qhov tseem ceeb tshwj xeeb.Qhov ntau dua qhov sib txawv ntawm PN hlws ris kub thiab lub teeb lub cev kub, lub thermal kuj ntau dua, thiab kev hloov ntawm lub teeb lub zog mus rau hauv thermal zog yog noj nyob rau hauv vain, thiab LED yog puas nyob rau hauv loj heev mob.Ib tug zoo structural engineer yuav tsum tsis tsuas yog xav txog cov qauv ntawm lub luminaire thiab thermal kuj ntawm lub LED, tab sis kuj xav txog seb cov duab ntawm lub luminaire yog tsim nyog, fashionable, tshiab, thiab ntawm chav kawm kev cia siab, kev ruaj ntseg thiab practicability.Los ntawm qhov kev xav ntawm kev xav, peb yuav tsum xav txog cov khoom ntawm qhov kev xav ntawm tus neeg siv.

Kev ua tau zoo hluav taws xob (electronic): Yog tias lub teeb pom kev zoo piv rau ib tug ntxhais, ces lub teeb yog nws lub ntsiab lus, qauv yog nws qhov tsos, electronics yog nws lub siab.(Nws yog ib txwm zoo nkauj thiab zam ntawm cov poj niam zoo nkauj uas nyiam cov neeg nyiam, nrog rau cov khoom lag luam.) Yog tias tus neeg tsis muaj lub siab, tsis muaj txoj sia.Yog tias lub teeb tsis muaj electrons, nws yuav tsis yog lub zog.Lub zog tsav tsheb zoo tuaj yeem txiav txim siab lub neej ntawm cov khoom.Cov qauv hluav taws xob thiab cov kev ntsuas feem ntau yog qhov nyuaj dua li cov qauv, thiab kev tshawb fawb thiab kev tsim kho thaum ntxov kuj tseem loj heev.Cov txheej txheem thev naus laus zis tam sim no thiab hloov tshiab tau hloov nrog txhua hnub dhau mus.Cov engineers yuav tsum siv zog ntau los kawm, nqus, disassemble thiab siv cov thev naus laus zis tshiab.Kev npaj ua ntej ntawm kev tsim hluav taws xob, kev siv lub sijhawm nruab nrab, thiab kev tsim cov txheej txheem tom qab yuav tsum tau tsim cov ntaub ntawv thiab cov ntaub ntawv.Qhov no kuj yog qhov cumbersome tshaj plaws hauv kev tsim.Piv txwv li: kev npaj ua ntej ntawm kev tsim hluav taws xob tsim, cov lus piav qhia ntawm cov khoom siv, cov qauv kev qhia tshwj xeeb, cov qauv kev nyab xeeb, kev cia siab ntawm hluav taws xob, kev xav tau ntawm cov khoom siv raw, kev ntsuam xyuas cov txheej txheem, thiab lwm yam yuav tsum tsim cov ntaub ntawv kaw lus.
