Kuv yuav ua li cas yog tias LED tsom teeb tawg thiab tsis teeb?
Thaum txhim kho lub teeb nyob rau hauv ntau tus neeg lub tsev, ntxiv rau cov teeb pom kev zoo siv rau cov teeb pom kev zoo, lawv kuj tseem yuav nruab qee qhov tsom teeb, xws li cov teeb tsom teeb rau ntawm lub qab nthab ntawm phab ntsa TV. Yog tias qhov muag teev ntawm cov tsom teeb no tawg, LED tsom teeb Yog tias nws tawg, nws tsis teeb, kuv yuav ua li cas yog tias nws flickers?
Qhov tseeb, nws tsis yooj yim los hloov lub teeb ntawm qhov tsom teeb. Ntev npaum li pom txoj hauv kev zoo, lub teeb ntawm lub tsom teeb tuaj yeem hloov tau yooj yim heev, thiab tsis tas yuav nug tus kws tshaj lij los kho nws, uas yog kim thiab siv sijhawm ntev.
Ua ntej, peb tua lub teeb ntawm lub tsom teeb kom ntseeg tau tias muaj kev nyab xeeb ntawm kev hloov, thiab tom qab ntawd siv lub taub hau lub taub hau kom rub lub nplhaib sab nraud kom tshem tawm tag nrho lub teeb. Tom qab hloov lub teeb, qaij rau sab saum toj thiab thawb tag nrho lub teeb.
Cov teeb pom kev zoo raug tshem tawm tuaj yeem muag rau cov chaw tsim khoom rau kev pab cuam tom qab muag. Feem ntau, lub warranty ntawm LED cov khoom yog tsawg kawg yog ob xyoos.
Txheeb xyuas qhov teeb meem
3W MR16 LED (12V (stabilized input) tsom teeb thiab hloov fais fab mov (12V/2.5A), txhua qhov hloov hluav taws xob nrog 6 ~ 8pcs tsom teeb txij li 6 txog 8pcs, tab sis tom qab ib nrab xyoo ntawm kev siv, muaj ntau pawg ntawm LED Lub teeb ci ntsa iab tshwm sim, Qee zaum, tag nrho cov khoom siv hluav taws xob hloov hluav taws xob kub (ntau tshaj 60 degrees), qhov hloov hluav taws xob hloov tau muab tso rau ntawm lub paj, thiab qhov cua kuj tseem tuaj yeem ua tau.Thaum kuaj qhov voltage thiab tam sim no, cov zis thiab cov tswv yim zoo li qub. LED yog ci ntsa iab, lub zog hloov pauv tsis muaj qhov tso tawm tam sim no ..
Kev tshuaj xyuas ntawm qhov ua tau
LED cov teeb pom kev tsis tshua muaj hluav taws xob xa mus rau lub teeb uas tus neeg tsav tsheb tau teeb tsa hauv M16 thiab M11 lub khob lub teeb thiab txuas ncaj qha rau lub tshuab hluav taws xob ntawm lub teeb halogen. Vim tias lub tshuab hluav taws xob hloov hluav taws xob tau tsim los rau lub teeb halogen, nws tsis haum rau kev siv lub zog ntawm LED tsav tsheb. Thaum peb LEDs txuas nrog hauv series thiab tom qab ntawd txuas nrog lub halogen lub teeb hloov pauv, muaj ob qhov teeb meem ntawm kev tsis pom kev thiab tsis tshua muaj flashing. Qhov ntsuas hluav taws xob ntawm lub teeb hluav taws xob qis halogen yog 12V. Txhawm rau ua kom lub neej ntev kev pab cuam ntawm lub teeb halogen, qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob hluav taws xob yog txhob txwm tsim kom qis dua qhov ntsuas hluav taws xob ntawm lub teeb halogen, feem ntau 11.3-11.5V. Cov pa hluav taws xob tsawg-voltage LED tsav tsheb yog Buck qauv, uas yuav tsum muaj tsawg kawg yog 0.3V voltage sib txawv thaum lub sijhawm ua haujlwm ib txwm, uas yog, VBuck=0.3V. Yog hais tias qhov hluav taws xob rau pem hauv ntej ntawm PN kev sib tshuam ntawm LED yog 3.4V, qhov sib npaug ntawm cov hluav taws xob pem hauv ntej ntawm peb LEDs yog VF=10.2V. Qhov hluav taws xob poob ntawm Schottky tag nrho tus choj yog li 1V, uas yog, VD=1V. Thaum lub input voltage VIN-(VD ntxiv rau VF)
Yuav ua li cas xaiv tsom teeb
Lub teeb tsom teeb tau muab faib ua ob hom: low-voltage thiab high-voltage. Cov neeg siv khoom nyiam xaiv cov teeb pom kev zoo uas tsis tshua muaj hluav taws xob, uas muaj lub neej ntev dua thiab ua haujlwm zoo dua. Lub luminous efficiency ntawm tsom teeb yog sawv cev los ntawm lub hwj chim yam. Lub zog loj dua, qhov zoo dua qhov kev ua haujlwm ntawm luminous. Lub zog ntawm cov teeb pom kev zoo tib yam yog hais txog 0.5, uas yog pheej yig. Lub hwj chim ntawm cov teeb pom kev zoo tuaj yeem ncav cuag 0.99, uas yog kim dua me ntsis. Spotlights feem ntau yog siv los txhim kho cov teeb pom kev zoo ntawm cov khoom dai kom zoo nkauj. Lawv feem ntau yog muab tso rau hauv qab nthab lossis phab ntsa. Spotlights feem ntau tso tawm qhov kub thiab txias thaum ua haujlwm, yog li koj yuav tsum yuav cov khoom zoo, txwv tsis pub yuav muaj kev phom sij rau kev nyab xeeb. Thaum siv lub teeb tsom teeb, nws yog qhov yuav tsum tau siv lub tshuab hloov pauv, thiab lub teeb hlaws yuav tsum yog qhov zoo, txwv tsis pub cov hlaws dai ntawm lub tsom teeb yuav yooj yim puas. Xav txog cov teeb pom kev zoo hlaws hauv qab nthab, tab sis nws yog qhov teeb meem heev los hloov. Txawm li cas los xij, qhov zoo ntawm cov teeb pom kev zoo ntawm kev ua lag luam tam sim no txawv, thiab nws yog qhov nyuaj rau kev paub qhov zoo ntawm qhov tsis zoo ntawm qhov muag liab qab.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri-pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag, LED chaw ntau pob teeb , LED High Bay, LED Classing Room Teeb, Yog tias koj xav yuav cov khoom lag luam zoo LED teeb pom kev zoo lossis muaj kev nkag siab ntau ntxiv ntawm daim ntawv thov ntawm LED teeb pom kev zoo, thov hu rau peb nug.
