LEDs tau txhim kho nyob rau hauv cov nqe lus ntawm lub teeb pom kev zoo, lub zog efficiency, nqi zog, ruggedness, thiab xim xaiv raws li ib tug tshwm sim ntawm kev loj hlob nyob rau hauv semiconductors, optics, cov ntaub ntawv, thiab manufacturing. Raws li qhov tshwm sim, kev siv teeb pom kev zoo rau cov khoom siv LED tam sim no nkag mus tau yooj yim, maj mam hloov cov hlau halide thiab kub siab sodium teeb. Thaum nws los txog rau txhua hom kev lag luam thiab kev lag luam teeb pom kev zoo, LED tau nrawm nrawm los ua tus qauv thev naus laus zis. Uptake hauv cov xwm txheej no tau txhawb nqa los ntawm ntau yam tseem ceeb.
Txhua lub lag luam yuav tsum siv zog rau qhov teeb pom kev zoo tshaj plaws thaum siv lub zog tsawg kawg nkaus, tshwj xeeb tshaj yog cov nqi hluav taws xob nce. Kev ua tau zoo yog ib qho tseem ceeb ntawm kev lag luam LED teeb pom kev zoo, ntxiv rau qhov zoo ntawm LED teeb nrog kev saib xyuas. Nws yog txhua yam hais txog Xim Rendering Index.
CRI yog txhais tau tias yog lub hom phiaj Performance index, xam ntawm qhov ntsuas ntawm 0 mus rau 100, uas piv lub teeb ci rau lub teeb uas tsim los ntawm ntuj tshav ntuj. Lub ntsiab lus dav ntawm CRI yog tias nws yog "kev ntsuas qhov zoo ntawm lub teeb xim." CRI ntawm ambient lub teeb yog 100. Cov CRIs ntawm cov feem ntau siv LED teeb qhov chaw poob ntawm 80 thiab 90. Cov xim rendering Performance index ntawm ib tug LED teeb qhov chaw yuav qhia tau zoo npaum li cas qhov chaw yuav illumination cov khoom los nthuav cov xim tiag tiag rau tus saib. thiab ze npaum li cas qhov chaw ntawd yuav ua raws li qhov ci ntsa iab, ntuj tshav ntuj.
Tab sis kev sib tham CRI yog tsis yooj yim sua yam tsis muaj kev sib tham txog cov xim kub. Cov xim kub ntawm lub teeb pom kev yog ntsuas hauv degrees Kelvin. Yog tias ob lub teeb ci muaj qhov kub thiab txias, nws raug nquahu kom ntsuas lawv CRIs rau ib leeg.
Qhov no txhais li cas rau kev lag luam thiab kev lag luam teeb pom kev zoo, ces?
Tus neeg saib xyuas tuaj yeem txiav txim siab seb lub teeb LED yuav ua tau zoo npaum li cas hauv ib yam khoom los ntawm kev saib nws cov xim rendering Performance index. Qhov no yog qhov tseem ceeb hauv kev ua haujlwm hauv tsev rau khoom, chaw xa khoom, chaw tsim khoom, thiab lwm qhov chaw lag luam lossis chaw lag luam. Tsis tsuas yog rau cov qauv kev nyab xeeb uas tsim nyog, tab sis tshwj xeeb tshaj yog nyob rau hauv cov neeg ua haujlwm yuav tsum muaj peev xwm nyeem cov cim ntawm lub thawv, qhov chaw, cov thawv ntim khoom, cov lus qhia, thiab phau ntawv.
Txhawm rau muab nws yooj yim, LED teeb pom kev zoo tso cai rau cov tsev muab cov teeb pom kev zoo tshaj plaws rau cov xwm txheej ua haujlwm, tsis yog lub teeb xiav-dawb monochromatic lossis lub suab paj nruag.
Nws yog qhov zoo los siv cov teeb pom kev lag luam LED. Cov neeg saib xyuas cov chaw tuaj yeem txhim kho qhov sib txawv ntawm qhov sib txawv thaum tswj lub teeb theem, txo tag nrho cov teeb uas xav tau, thiab txhim kho qhov sib xws uas siv ntau qhov kev teeb pom kev sib faib. Raws li qhov tshwm sim, cov nqi khiav lag luam raug txo tag nrho thaum ua kom cov neeg ua haujlwm tsim khoom, zoo, thiab kev nyab xeeb.
