Nws yog ib qho tshwm sim heev uas cov teeb coj teeb ua tsaus thiab tsaus dua thaum lawv siv. Soj ntsuam cov laj thawj uas tuaj yeem ua rau tsaus ntujLED teeb, uas tsis muaj dab tsi ntau tshaj li peb lub ntsiab lus hauv qab no.

1. Tsav puas lawm

LED teeb hlaws yuav tsum ua haujlwm ntawm qhov qis DC voltage (qis dua 20V), tab sis peb lub zog hluav taws xob ib txwm yog AC high voltage (AC 220V). Txhawm rau tig lub zog hluav taws xob mus rau lub zog xav tau los ntawm lub teeb hlaws, peb xav tau lub cuab yeej hu ua "LED tsis tu ncua tam sim no tsav lub zog".

Raws li txoj cai, ntev npaum li qhov tsis sib xws ntawm tus neeg tsav tsheb sib phim lub teeb hlaws phaj, nws tuaj yeem txuas txuas ntxiv thiab siv tau ib txwm. Sab hauv ntawm tus tsav tsheb yog complex. Qhov tsis ua haujlwm ntawm ib qho khoom siv (xws li capacitor, rectifier, thiab lwm yam) tuaj yeem ua rau qhov kev hloov pauv ntawm cov zis hluav taws xob, thiab tom qab ntawd ua rau lub teeb ci.

Kev puas tsuaj ntawm tus tsav tsheb yog qhov ua txhaum ntau tshaj plaws hauv cov teeb ci LED. Feem ntau nws tuaj yeem daws tau tom qab hloov tus tsav tsheb.

2.Led hlawv

LED nws tus kheej yog tsim los ntawm lub teeb hlaws ib qho los ntawm ib qho. Yog hais tias ib qho los yog ib feem ntawm lawv tsis nyob rau, nws yuav tsum ua kom tsaus rau tag nrho lub teeb. Lub teeb hlaws feem ntau txuas nrog hauv cov koob thiab tom qab ntawd nyob rau hauv qhov sib npaug - yog li yog tias lub teeb hlaws raug hlawv, ib pawg ntawm cov hlaws teeb yuav tsis teeb.

Muaj qhov pom tseeb dub me ntsis ntawm qhov chaw ntawm lub teeb ci hlaws. Pom nws, txuas rau sab nraub qaum nrog ib lub xov hlau thiab luv luv nws; Los yog lub teeb hlaws tshiab tuaj yeem daws qhov teeb meem.

Coj qee zaus hlawv ib qho, nws yuav yog los ntawm lub sijhawm. Yog tias koj hlawv ntau zaus, koj yuav tsum xav txog qhov teeb meem ntawm lub tsav - lwm qhov tshwm sim ntawm kev tsav tsis ua haujlwm yog hlawv cov hlaws teeb.

3.LED lub teeb attenuation

Lub npe hu ua lub teeb lwj yog qhov ci ntsa iab ntawm lub teeb pom kev tau qis dua thiab qis dua - uas yog pom tseeb dua hauv cov teeb pom kev zoo thiab cov teeb fluorescent.

LED teeb tsis tuaj yeem zam lub teeb lwj, tab sis nws lub teeb nrawm nrawm kuj qeeb, thiab feem ntau nyuaj rau pom qhov hloov pauv ntawm qhov muag liab qab. Txawm li cas los xij, nws tsis tau txiav txim siab tias cov coj tsis zoo, lossis tsis zoo lub teeb hlaws phaj, lossis vim yog lub hom phiaj tseem ceeb xws li cov cua sov tsis zoo, lub teeb pom kev zoo ntawm LED yuav nrawm dua.
