1. LED tso zis luminous flux (LM naj npawb) txawv, thiab tus nqi sib txawv. LED siv rau LED teeb yuav tsum ua tau raws li cov chav kawm laser kuv tus qauv.
2. Lub LED muaj zog antistatic muaj peev xwm muaj lub neej ntev thiab tus nqi siab. Feem ntau, tsuas yog LED uas nws ib leeg antistatic siab dua 700V tuaj yeem siv rau LED teeb pom kev zoo.
3. LEDs nrog wavelength zoo sib xws muaj tib xim. Yog tias cov xim yuav tsum tau ua kom zoo ib yam, tus nqi siab. Nws yog ib qho nyuaj rau cov tuam txhab uas tsis muaj LED spectrophotometers los tsim cov khoom nrog cov xim ntshiab.
4. Cov dej ntws tam sim no
LED yog unidirectional conductive luminous lub cev. Yog tias muaj qhov rov qab tam sim no, nws yog hu ua to. LEDs nrog cov xau loj tam sim no muaj lub neej luv luv thiab tus nqi qis.
5. LEDs nrog lub teeb sib txawv - emitting ces kaum muaj lub teeb sib txawv - emitting ces kaum. Lub kaum ntse ntse tshwj xeeb, tus nqi siab dua. Xws li tag nrho diffusion lub kaum sab xis, tus nqi siab dua.
6. Lub neej ncua kev sib txawv, thiab tus yuam sij rau kev ua tau zoo yog lub neej ncua. Lub neej yog txiav txim los ntawm lub teeb lwj. Tsawg lub teeb lwj, lub neej ntev thiab tus nqi siab.
7. Chip
Lub luminous lub cev ntawm LED yog ib nti, thiab tus nqi ntawm cov chips sib txawv heev. Chips hauv Nyiv thiab Tebchaws Meskas yog kim dua. Feem ntau, cov nqi ntawm cov chips ua nyob rau hauv Taiwan thiab Tuam Tshoj yog qis dua nyob rau hauv Nyiv thiab Tebchaws Meskas (CREE).
8. Chip size Qhov loj ntawm lub nti yog qhia los ntawm sab ntev. Qhov zoo ntawm cov nti loj LED zoo dua li ntawm cov nti me me. Tus nqi yog proportional rau qhov loj ntawm lub nti.
9. Colloid Lub colloid ntawm cov LEDs zoo tib yam yog epoxy resin. LEDs nrog anti - ultraviolet thiab hluav taws kub retardants yog kim dua. High - zoo sab nraum zoov LED teeb pom kev zoo yuav tsum tiv thaiv - ultraviolet thiab fireproof. Txhua yam khoom yuav muaj qhov sib txawv. Cov qauv sib txawv yog tsim rau cov hom phiaj sib txawv. Kev ntseeg tau tsim ntawm LED teeb pom kev zoo suav nrog: hluav taws xob kev nyab xeeb, kev nyab xeeb hluav taws, siv ib puag ncig kev nyab xeeb, kev nyab xeeb txhua yam, kev nyab xeeb kev noj qab haus huv, kev nyab xeeb siv sijhawm thiab lwm yam. Los ntawm kev xav ntawm hluav taws xob kev nyab xeeb, nws yuav tsum ua raws li cov qauv thoob ntiaj teb thiab lub teb chaws.
Raws li LED yog ib yam khoom tshiab, Tuam Tshoj' lub teb chaws cov qauv yog lagging qab, tab sis lub teb chaws muab cov khoom tsim nyog xeem. Tus nqi ntawm LED teeb pom kev zoo nrog daim ntawv pov thawj kev nyab xeeb thoob ntiaj teb (xws li GS, CE, UL, thiab lwm yam) thiab daim ntawv pov thawj cov khoom hauv lub tebchaws yog siab dua vim tias cov khoom no muaj kev ruaj ntseg tsim. Cov neeg siv khoom yuav tsum tau them sai sai rau qhov tseeb ntawm daim ntawv pov thawj. Tsis muaj ntau lub tuam txhab uas muaj ntawv pov thawj kev nyab xeeb thoob ntiaj teb thiab cov khoom pov thawj hauv lub tebchaws.
Hais txog kev noj qab haus huv, tus nqi ntawm cov khoom tsim nrog cov khoom tsis yog - tshuaj lom yog siab dua, tshwj xeeb tshaj yog sab hauv tsev LED teeb pom kev zoo. Tsis txhob greedy rau pheej yig LED teeb pom kev zoo nrog peculiar tsw. Tsuas yog ob peb lub tuam txhab LED siv tsis yog - cov khoom siv tshuaj lom los tsim. Cov txheej txheem ntawm kev txheeb xyuas tuaj yeem ncaj qha siv lub qhov ntswg los cais, cov khoom tsis hnov tsw yog pheej yig dua li cov khoom tsis muaj ntxhiab. Cov tshuaj lom xws li txhuas, mercury, thiab cadmium yuav tsum tau soj ntsuam los ntawm cov kws tshaj lij. Los ntawm kev xav txog kev nyab xeeb ntawm ib puag ncig, muaj kev ntseeg siab plua plav - pov thawj thiab ya raws - pov thawj tsim, thiab tus nqi ntawm cov khoom siv hluav taws xob nrog hluav taws kub - pov thawj, UV - pov thawj, thiab qis - kub tiv thaiv kev tawg yog siab.
