Nws yog ib qho tshwm sim heev uas LED teeb ua tsaus nti thaum lawv siv. Cov laj thawj tseem ceeb yog peb lub ntsiab lus hauv qab no:
Tsav tsheb puas lawm
LED teeb hlaws yuav tsum tsis tshua muaj DC voltage (qis dua 20V), tab sis peb ib txwm mains yog AC high voltage (AC 220V). Txhawm rau tig lub zog hluav taws xob rau hauv hluav taws xob xav tau los ntawm lub teeb hlaws, ib lub cuab yeej hu ua" LED tas li tam sim no tsav fais fab mov" yog xav tau. Nyob rau hauv txoj kev xav, tsuav yog tus tsav tsheb' qhov tsis sib xws ntawm lub teeb hlaws lub rooj tsavxwm, nws tuaj yeem ua haujlwm tsis tu ncua thiab siv ib txwm. Sab hauv ntawm tus neeg tsav tsheb yog qhov nyuaj dua, txhua yam khoom siv (xws li capacitor, rectifier, thiab lwm yam) tsis ua haujlwm yuav ua rau cov zis hluav taws xob hloov pauv, thiab tom qab ntawd ua rau lub teeb dim.
Kev Kho Mob: Kev puas tsuaj ntawm tus tsav tsheb yog hom kev ua tsis tiav hauv LED teeb, thiab feem ntau nws tuaj yeem daws tau tom qab hloov tus tsav tsheb.
LED hlawv tawm
LED nws tus kheej yog tsim los ntawm lub teeb hlaws ib qho los ntawm ib qho. Yog hais tias ib los yog ib feem ntawm lawv tsis kaj, nws yuav inevitably ua rau tag nrho cov teeb dim. Lub teeb hlaws feem ntau txuas nrog hauv cov koob thiab tom qab ntawd nyob rau hauv qhov sib npaug - yog li yog tias ib lub teeb hlaws kub hnyiab tawm, ib pawg ntawm cov hlaws teeb yuav tsis teeb. Kev kho mob: Muaj cov pob dub pom tseeb nyob rau saum npoo ntawm lub teeb ci ntsa iab, pom nws, txuas rau sab nraum qab ntawm nws nrog ib lub xaim, thiab luv-circuit nws; los yog hloov lub teeb hlaws tshiab los daws qhov teeb meem.
Ib qho ntawm cov LEDs qee zaus kub hnyiab, nws yuav yog qhov xwm txheej. Yog tias nws tau hlawv ntau zaus, qhov teeb meem tsav tsheb yuav tsum tau txiav txim siab - lwm qhov tshwm sim ntawm kev tsav tsheb tsis ua haujlwm yog hlawv cov hlaws teeb.
LED teeb pom kev zoo
Lub npe hu ua lub teeb lwj yog qhov ci ntsa iab ntawm lub cev luminous tau qis dua thiab qis dua - qhov xwm txheej no pom tseeb dua hauv cov teeb pom kev zoo thiab cov teeb fluorescent. LED teeb muaj peev xwm' tsis txhob zam lub teeb lwj, tab sis nws lub teeb lwj ceev kuj qeeb, thiab nws feem ntau nyuaj rau pom kev hloov pauv ntawm qhov muag liab qab. Txawm li cas los xij, nws tsis tau txiav txim siab tias cov LEDs tsis zoo, lub teeb pom kev tsis zoo, lossis lub hom phiaj tseem ceeb xws li cov cua sov tsis zoo, ua rau lub teeb pom kev sai dua.
