Daim ntawv thov ntawm high-end dawb lub teeb illumination:
Laser headlights thiab laser projectors tau ua ib qho kev siv ntawm high-end illumination nyob rau hauv lub xyoo caum dhau los. Thaum pib, lub teeb dawb tau tsim los ntawm kev siv blu-duab tshav LD thiab Ce: YAG fluorescent ceramics (headlights) los yog los ntawm casting LD rau ntawm phosphor pleev xim rau xim-log phaj (projector). Raws li lub zog laser nce, cov cua sov tsim los ntawm kev hloov pauv ntawm electro-optical efficiency nce qhov kub thiab txias thiab deteriorates quantum conversion efficiency ntawm cov khoom fluorescent, uas yog hu ua thermal quenching, ua rau lub teeb lwj. Nws qhia tau hais tias qhov sib piv ntawm luminous siv ntawm fluorescent ib leeg siv lead ua, fluorescent iav, thiab fluorescent ceramics uas txawv nrog kub. Nws yog qhov pom tseeb tias ib qho siv lead ua muaj qhov ua haujlwm qis thermal quenching ntawm qhov kub thiab txias vim nws cov thermal conductivity siab.
Raws li qhov tshwm sim, fluorescent ib leeg siv lead ua zoo li yog qhov kev xaiv thawj rau lub teeb taub hau thiab lub teeb ci siab (> 20,000 lumens) projectors nrog LD-raws li lub teeb xyaw. Txawm li cas los xij, fluorescent ib leeg siv lead ua tsis tuaj yeem hloov cov khoom siv fluorescent ncaj qha raws li cov qauv tsim kho qhov muag uas twb muaj lawm. Kev rov tsim kho qhov muag kho qhov muag yog qhov tsim nyog, tab sis nws nce tus nqi thiab tsim kev pheej hmoo rau cov chaw tsim khoom.
Cov tshuaj tshiab - tshav kub-resistant phosphor:
Taiwan Applied Crystal (TAC) tau ua tiav cov khoom siv hluav taws xob tiv thaiv phosphor uas txawv ntawm cov khoom siv sib txawv (Fig. 2). Nyob rau hauv kev khiav hauj lwm kub siab tshaj 200 ° C, nws luminous siv mus txog 20% siab tshaj li cov pa phosphors (Fig. 3). Qhov no txhais tau hais tias cov hluav taws kub-resistant phosphors tau zoo dua QE thiab luminous siv nyob rau hauv cov xwm txheej uas tus thawj kho qhov muag tsim tsis nce tus tsim los yog tus nqi ntawm cov khoom cua kub dab dej. Qhov no tso cai rau cov khoom siv teeb pom kev zoo nrog LD-raws li lub teeb pom kev zoo los hloov LED-raws li lub teeb pom kev zoo lub cav teeb pom kev zoo lossis projectors yooj yim dua thiab raug nqi zoo.
