Kev ua tau zoo ntawm lub teeb (kev faib tawm lub teeb): Kev ua tau zoo ntawm lub teebCov teeb vaj huam sib luag LEDFeem ntau yog cov kev cai ua tau zoo ntawm qhov ci ntsa iab, spectrum thiab chromaticity. Raws li tus qauv kev lag luam tshiab "Semiconductor LED Test Method", feem ntau muaj qhov ci ntsa iab wavelength, spectral radiance bandwidth, axial illuminance intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity thiab dominant wavelength, Color rendering index thiab lwm yam parameters. Cov teeb LED vaj huam sib luag feem ntau siv cov teeb dawb LEDs, qhov kub xim, color rendering index thiab illuminance yog qhov tseem ceeb, nws yog ib qho cim qhia tseem ceeb ntawm lub teeb pom kev zoo thiab cov nyhuv, thiab xim purity thiab dominant wavelength feem ntau tsis tas yuav tsum muaj.

Kev ua tau zoo ntawm lub teeb (qauv): Lub zog ntawm lub teeb LED thiab lub zog rau lub teeb pom kev zoo yog ib qho tseem ceeb hauv kev lag luam LED. Tib lub sijhawm, qhov kub ntawm PN junction ntawm LED thiab qhov teeb meem ntawm lub cev kub ntawm lub teeb yog qhov tseem ceeb heev. Qhov sib txawv ntawm qhov kub ntawm PN junction thiab qhov kub ntawm lub cev teeb ntau dua, qhov kev tiv thaiv thermal ntau dua, thiab kev hloov pauv ntawm lub zog teeb mus rau hauv lub zog thermal raug siv tsis muaj txiaj ntsig, thiab LED raug puas tsuaj rau cov xwm txheej hnyav. Tus kws tsim qauv zoo yuav tsum tsis txhob tsuas yog xav txog cov qauv ntawm lub teeb thiab qhov kev tiv thaiv thermal ntawm LED, tab sis kuj xav txog seb cov duab ntawm lub teeb puas tsim nyog, zam, tshiab, thiab tau kawg kev ntseeg siab, kev saib xyuas thiab kev siv tau. Los ntawm qhov kev xav ntawm kev xav, peb yuav tsum xav txog cov khoom los ntawm qhov kev xav ntawm tus neeg siv.

Kev ua tau zoo ntawm hluav taws xob (hluav taws xob): Yog tias lub teeb pom kev zoo piv rau ib tug ntxhais, ces lub teeb yog nws lub ntsiab lus, cov qauv yog nws qhov tsos, cov khoom siv hluav taws xob yog nws lub siab. (Nws ib txwm yog qhov zoo nkauj thiab zam ntawm cov poj niam zoo nkauj uas nyiam tib neeg lub siab, nrog rau cov khoom.) Yog tias ib tug neeg tsis muaj lub siab, tsis muaj txoj sia. Yog tias lub teeb tsis muaj hluav taws xob, nws yuav tsis yog lub hauv paus fais fab. Lub hauv paus fais fab tsav tsheb zoo kuj tuaj yeem txiav txim siab lub neej ntawm cov khoom. Cov qauv hluav taws xob thiab cov kev teeb tsa feem ntau nyuaj dua li cov qauv, thiab kev tshawb fawb thiab kev txhim kho thaum ntxov kuj loj heev. Cov qauv thev naus laus zis tam sim no thiab kev hloov tshiab hloov pauv txhua hnub. Cov kws ua haujlwm yuav tsum siv zog ntau los kawm, nqus, rhuav tshem thiab siv cov thev naus laus zis tshiab. Kev npaj ua ntej ntawm kev tsim hluav taws xob, kev siv nruab nrab lub sijhawm, thiab kev tsim cov txheej txheem tom qab yuav tsum tsim cov ntaub ntawv thiab tsim cov ntaub ntawv. Qhov no kuj yog qhov nyuaj tshaj plaws hauv kev tsim qauv. Piv txwv li: daim phiaj xwm ua ntej ntawm kev tsim hluav taws xob, cov lus piav qhia txog khoom, cov qauv qhia txog tus qauv, cov qauv qhia txog kev nyab xeeb, tus nqi xav tau kev ua haujlwm hluav taws xob, cov kev cai ntawm cov txheej txheem, kev ntsuam xyuas cov khoom siv raw, cov txheej txheem sim, thiab lwm yam yuav tsum tsim cov ntaub ntawv system.
