Txog kev txhim kho xim qhia qhov ntsuas ntawm dawb LED teeb pom kev zoo
Tam sim no, cov thev naus laus zis LED dawb tsis paub tab txaus hais txog kev ua xim, uas tuaj yeem dhau los ua ib qho teeb meem tseem ceeb txwv tsis pub LED ua lub teeb pom kev zoo. Lub teeb pom kev muaj qhov xav tau nruj ntawm qhov ntsuas xim xim CRI hauv cov teeb pom kev zoo. Nrog kev txhim kho txuas ntxiv ntawm LED thev naus laus zis, nws muaj peev xwm siv LED ua lub teeb pom kev zoo.
Lub teeb dawb yog lub teeb sib xyaw, thiab lub teeb ntawm ntau yam xim muaj nyob hauv lub teeb dawb tuaj yeem yooj yim decomposed los ntawm prism. LED yog lub teeb pom kev nrog cov xim ntau dua. Qhov dav xim gamut no tau tso lub hauv paus theoretical rau kev ua kom muaj xim zoo ntawm cov khoom lag luam teeb pom kev zoo.
Lub teeb yog cov khoom siv nrog yoj-particle duality. Cov khoom siv no muaj cov yam ntxwv ntawm nthwv dej thiab cov yam ntxwv ntawm cov khoom, uas ua rau nws muaj cov yam ntxwv zoo sib xws. Yog li ntawd, hais txog qhov xwm txheej ntawm lub teeb thiab cov yam ntxwv ntawm LEDs, Nws yog qhov ua tau rau LEDs los ua qhov chaw teeb pom kev zoo.
Tam sim no lub teeb pom kev zoo LED thev naus laus zis feem ntau lees txais cov txheej txheem tsim khoom ntawm cov xim xiav coated nrog phosphor hmoov, uas ua raws li lub teeb pom kev zoo ntawm lub raj roj fluorescent hauv qee qhov kev nkag siab. Cov thev naus laus zis no muaj los ntawm kev yug los vim tsis muaj lub teeb liab thiab ntsuab ntsuab. Txhawm rau txhawm rau txhawm rau txhawm rau qhov ua tsis tiav ntawm cov xim tsis txaus ua qhov ntsuas, phosphor thev naus laus zis tau dhau los ua lub hauv paus tseem ceeb ntawm kev lag luam.
Chip xiav yog coated nrog phosphor los ua lub teeb pom kev zoo thev naus laus zis. Cov thev naus laus zis no tuaj yeem tsim lub teeb dawb nrog cov txiaj ntsig zoo hauv txoj cai. Txawm li cas los xij, vim tsis muaj kev hloov pauv tau yooj yim rau ib puag ncig thaum siv, qhov sib txawv ntawm qhov kev xav thiab qhov khoom tiag yog tshwm sim. Qhov sib txawv yog qhov ntau vim yog qhov cuam tshuam ntawm LED cov cua sov ua kom sov ntawm phosphor.
