Feem ntau, rau pem hauv ntej hluav taws xob ntawm ib LED yog nruab nrab ntawm 1.8 txog 3.3 qhov hluav taws xob . Nws txawv ntawm cov xim LED . Liab LED feem ntau poob ntawm 1.7 txog 2.0 qhov hluav taws xob , tab sis txij li ob qho tib si hluav taws xob poob thiab lub teeb zaus nce nrog band sib txawv, xiav LED tuaj yeem poob ntawm 3 mus rau 3.3 qhov hluav taws xob.
Ib yam li ntawd, nws tau nug, 220v LED tuaj yeem siv rau 110v?
Yog tias tsis muaj txoj cai tswj hwm sab hauv, koj ua tau sim nws a 110v wb circuit thiab qhov phem tshaj ntawd yuav tshwm sim yog tias nws yuav lub teeb dimly los yog tsis txhua. Txawm li cas los xij yog tias lub teeb muaj lub regulator, nws nyuaj rau twv seb nws yuav ua li cas yuav ua nrog ib qho input voltage hauv qab nws rated voltage.
Ib yam li ntawd, koj ua li cas kuaj lub LED? Rau xeem koj LED , kov qhov taub ntawm qhov kev sojntsuam dub mus rau lub cathode, lossis luv kawg ntawm qhov LED . Kov qhov taub ntawm qhov kev sojntsuam liab mus rau anode, uas yuav tsum yog qhov ntev dua.
Yog li ntawd, dab tsi voltage yog lub teeb?
Common voltages yog 120V , 130V, los yog tsawg-voltage qhov muag teev zoo li 12V. Cov watts hais txog kev ua haujlwm uas tuaj yeem ua tau los ntawm cov hluav taws xob tam sim no, qhov no, lub teeb yuav ci li cas. Lub teeb 100-watt yuav muab koj lub teeb ntau dua li 60-watt teeb.
Yuav ua li cas koj kuaj tus tsav tsheb LED nrog lub multimeter?
Yuav Ntsuas Li Cas Diode nrog Multimeter
- Txuas cov hlau lead dub mus rau COM lub davhlau ya nyob twg ntawm lub multimeter.
- Txuas cov hlau lead liab mus rau Ω davhlau ya nyob twg, tshwj tsis yog koj tus qauv tshwj xeeb txawv.
- Tig lub dial mus rau lub cim diode ntawm lub multimeter.
- Qhib lub multimeter.
- Xaiv lub LED liab tsis tu ncua.

Qhov txawv ntawm qhov xim kub ntawm LED teeb yog dab tsi?
Xaiv Txoj Cai Xim - Tus Kelvin Nplai Ib tus lej kelvin qis txhais tau tias lub teeb pom daj dua; cov lej kelvin ntau dua txhais tau tias lub teeb yog whiter lossis bluer. CFLs thiab LEDs yog tsim kom haum rau cov xim ntawm cov qhov muag teev ntawm 2700-3000K. Yog tias koj xav tau lub teeb dawb, nrhiav qhov muag teev 3500-4100K
Qhov voltage ntawm txoj kev teeb yog dab tsi?
Qhov hluav taws xob ua haujlwm tshaj plaws yog 120 volts (62%) ua raws li 240 volts (28%). Feem ntau cov chaw uas muaj teeb pom kev zoo (82%) siv cov photocells ib tus neeg los tswj kev ua haujlwm ntawm / tawm ntawm lub teeb
Dab tsi yog qhov txawv ntawm qhov txias dawb thiab hnub ci LED qhov muag teev?
Cov xim ntawm lub teeb yog ntsuas los ntawm Kelvin (K) nplai. Piv txwv li, sov dawb LEDs yog 2700K txog 3200K, nruab hnub nrig yog nruab nrab ntawm 4000K txog 4500K, thiab txias dawb yog nyob nruab nrab ntawm 5000K txog 6200K
Dab tsi yog qhov laj thawj thiab nws qhov tseem ceeb hauv qhov xwm txheej tsis saib xyuas yog dab tsi?
Qhov ua rau sib thooj yog kev ua, txawm tias txhob txwm ua lossis tsis saib xyuas, uas tau txiav txim siab ua rau lwm tus puas tsuaj, raug mob, lossis raug kev txom nyem. Nws yog ib qho tseem ceeb uas cov tsev hais plaub tsim kom muaj qhov xwm txheej ntawm tus kheej raug mob vim tsis yog txhua tus thiab txhua yam uas ua rau muaj kev raug mob tuaj yeem raug cai
Dab tsi yog qhov voltage ntawm 12v roj teeb?
cav 12,6v Ib yam li ntawd, nws tau nug, pes tsawg volts yuav tsum tau them tag nrho 12v roj teeb nyeem? 12,6 kwv Ib sab saum toj no, qhov siab tshaj them hluav taws xob rau lub roj teeb 12 volt yog dab tsi? Tus nqi them voltage yog nruab nrab ntawm 2.
