Nws yog ib qho tshwm sim heev uas LED teeb ua tsaus nti thaum lawv siv. Muaj peb qhov laj thawj uas tuaj yeem ua rau LED teeb dim:.
Tsav puas lawm
LED chips yuav tsum tau ua haujlwm ntawm qhov qis DC voltage (qis dua 20V), tab sis peb lub zog hluav taws xob niaj hnub yog siab AC voltage (220V AC). Txhawm rau tig lub zog hluav taws xob mus rau hauv hluav taws xob xav tau rau LED chips, lub cuab yeej hu ua "LED tsis tu ncua tam sim no tsav tsheb fais fab" yog xav tau.
Nyob rau hauv txoj kev xav, ntev npaum li qhov tsis sib xws ntawm tus neeg tsav tsheb sib tw nrog LED board, nws tuaj yeem ua haujlwm tsis tu ncua thiab siv tau ib txwm. Cov qauv sab hauv ntawm tus neeg tsav tsheb yog qhov nyuaj heev, thiab txhua yam khoom siv (xws li lub capacitor, rectifier, thiab lwm yam) uas ua haujlwm tsis zoo yuav ua rau muaj kev hloov pauv ntawm cov zis hluav taws xob, uas tuaj yeem ua rau lub teeb pom kev tsaus.
Kev puas tsuaj tsav tsheb yog hom kev ua haujlwm tsis zoo hauv LED teeb pom kev zoo, uas feem ntau tuaj yeem daws tau los ntawm kev hloov tus tsav tsheb.
LED hlawv tawm
LED nws tus kheej yog tsim los ntawm kev sib txuas ntawm cov hlaws dai, thiab yog tias ib qho lossis ib feem ntawm lawv tsis teeb, nws yuav ua rau tag nrho lub teeb tsis dim. Lub teeb hlaws feem ntau txuas nrog hauv koob thiab tom qab ntawd nyob rau hauv tib lub sijhawm - yog li yog tias ib lub hlaws kub hnyiab tawm, nws yuav ua rau cov hlaws hlaws tsis teeb.
Muaj qhov pom tseeb dub me ntsis ntawm qhov chaw ntawm lub teeb ci hlaws. Nrhiav nws thiab txuas ib lub xaim rau nws sab nraub qaum kom luv-circuit nws; Xwb, hloov lub teeb lub teeb nrog ib qho tshiab tuaj yeem daws qhov teeb meem.
Qee zaus, ib qho LED hlawv tawm, nws yuav yog ib qho xwm txheej. Yog tias nws nquag hlawv tawm, ces cov teeb meem tsav tsheb yuav tsum tau txiav txim siab - lwm qhov tshwm sim ntawm kev tsav tsis ua haujlwm yog qhov kub ntawm LED chips.
LED teeb pom kev zoo
Lub npe hu ua lub teeb lwj yog hais txog qhov txo qis ntawm lub cev luminous, uas tau tshaj tawm hauv cov teeb pom kev zoo thiab cov teeb fluorescent.
LED teeb kuj tseem tsis tuaj yeem zam lub teeb lwj, tab sis lawv lub teeb tawg yog qhov qeeb qeeb, thiab feem ntau nyuaj rau pom kev hloov pauv ntawm qhov muag liab qab. Tab sis nws tsis tuaj yeem txiav txim siab tias cov LEDs tsis zoo, lossis cov hlaws tsis zoo, lossis lub hom phiaj tseem ceeb xws li cov cua sov tsis zoo tuaj yeem ua rau lub teeb tawg ntawm LED kom nrawm.
