CCT (Correlated Color Temperature) sawv cev rau cov xim ntawm lub teeb dawb. Lub teeb dawb tuaj yeem sov li tswm ciab lossis txias zoo li fluorescent lossis hnub dhau los thiab ntau xim nyob rau hauv -nruab nrab. LED teeb qhov chaw siv cov xim sib raug zoo los ntsuas cov xim ntawm lub teeb dawb, raws li kev xav ntawm Dub -Lub Cev Radiator. Hauv cov ntsiab lus yooj yim, nws ntsuas qhov xim ntawm lub teeb dawb yog tsim thaum cov khoom siv hlau dub, zoo li tus nees - khau yog rhuab mus rau qhov kub ntawm Kelvin. LEDs tau muab qhov sib txheeb xim kub (CCT). Rau cov dawb ntsuas los ntawm CCT, raws li cov dub - lub cev txoj kev xav, xiav tshwm sim ntawm qhov kub thiab txias (6500K), thaum liab tshwm sim ntawm qhov kub thiab txias (1600K).
Diode LED cov khoom, uas muaj nyob rau hauv - Tshuag thiab npaj xa tuaj, thaj tsam ntawm 2000K (tseem ceeb) thiab 6500K (hnub dhau los) thiab peb tuaj yeem tsim cov chaw tsim khoom raws li CCT ntawm 2000K thiab 7000K.
Nthuav qhov tseeb txog Correlated Xim Kub:
1. The human eye can see the difference between warmer color temperatures easier than the difference between cooler color temperatures. This difference is called "Just Noticeable Difference" (JND) and, according to scientists, we can discern the difference in warmer color temperatures by 100K and in cooler temperatures by 500K. This is why Diode LED offers many in-stock color temperature options between 2000K and 4200K, but less off-the-shelf options above 4200K.
2. Binning specifications ntawm cov chaw tsim tshuaj paus tuaj yeem cuam tshuam qhov tseeb CCT ntawm LED nti.. Binning yog cov txheej txheem uas LEDs raug kuaj thiab txheeb raws li ntau qhov kev ntsuas, suav nrog Correlated Xim Kub. Thaum lub sij hawm tsim khoom, LEDs yuav sib txawv, txawm nyob rau hauv tib batch. Qhov sib txawv ntawm txhua qhov LED tuaj yeem yog qhov tseem ceeb thiab yog li LEDs raug kuaj, txheeb thiab xa mus rau kev lag luam hauv subclasses lossis pab pawg hu ua bins. Diode LED siv nruj binning specifications yog li thaum peb muab 3000K, qhov sib txawv ntawm CCT ntawm ib qho LED nti yog nyob rau hauv JND ntau yam uas tau teev tseg saum toj no. Tighter binning yog kim dua vim tias tsis yog tag nrho cov LEDs tsim tau raug xaiv los siv rau hauv cov khoom siv teeb pom kev zoo.
3. Daim ntawv foos tseem tuaj yeem hloov CCT. Piv txwv li, lub teeb tsis muaj dej tsis muaj dej muaj txheej txheej uas yog tias tsis ua tib zoo saib xyuas los ntawm cov chaw tsim khoom tuaj yeem hloov pauv CCT thiab teeb pom kev zoo ntawm cov khoom.
