Dab tsi yog siv los ua kom tiav cov LEDs dawb?
Tam sim no, muaj peb txoj hauv kev tseem ceeb rau LED kom ua tiav lub teeb dawb:
(1) Synthesize dawb lub teeb los ntawm LED liab, xiav thiab daj peb-xim multi-chip ua ke;
Qhov zoo: kev ua haujlwm siab, tswj tau xim kub, zoo xim rendering.
Qhov tsis zoo: Qhov sib txawv ntawm lub teeb tawg ntawm peb lub ntsiab xim ua rau cov xim tsis ruaj tsis khov, qhov nyuaj tswj Circuit Court thiab tus nqi siab.
(2) Lub xiav LED nti ua rau lub teeb daj phosphor, thiab lub teeb dawb yog tsim los ntawm lub teeb xiav ntawm LED thiab lub teeb daj-ntsuab tawm los ntawm phosphor.
Txhawm rau hloov cov xim rendering kev ua tau zoo, ib qho me me ntawm cov phosphor liab tuaj yeem ntxiv rau nws, lossis ib qho tsim nyog ntawm ntsuab thiab liab phosphors ntxiv rau tib lub sijhawm;
Qhov zoo: kev ua haujlwm siab, kev npaj yooj yim, kev ruaj ntseg kub thiab zoo xim rendering.
Disadvantages: tsis zoo sib xws, xim kub, lub kaum sab xis hloov.
(3) Qhov ze-ultraviolet LED nti excites lub phosphor kom emit peb-xim hluavtaws dawb lub teeb.
Qhov zoo: zoo xim rendering, yooj yim npaj.
Qhov tsis zoo: Tam sim no, kev ua haujlwm ntawm LED chips tsawg, muaj teeb meem ntawm ultraviolet lub teeb to, thiab qhov teeb meem ntawm qhov kub thiab txias ntawm phosphors yuav tsum tau daws.
