Yog li lawv ua haujlwm ntawm AC thiab DC . Tsis zoo li cov roj teeb qub qub, CFLs thiab LED teeb yuav tsis ua haujlwm rau DC raws li lawv tau haum nrog lub inbuilt circuitry uas rectifies AC rau DC . Tab sis txaus siab DC hluav taws xob yuav ua rau mus tas li tsis ua haujlwm ntawm kev ua haujlwm ntawm lub cuab yeej.
Raws li, LED teeb ua haujlwm ntawm AC lossis DC?
Hauv feem ntau daim ntawv thov LEDs yog tsav los ntawm ib DC fais fab mov. LEDs haus DC tam sim no los tsim teeb ; nrog AC tam sim no LED tsuas yog yuav taws thaum cov dej ntws tam sim no nyob rau hauv qhov kev taw qhia kom raug. AC siv rau ib qho LED yuav ua rau nws ntsais muag thiab tawm, thiab ntawm qhov ntau zaus LED yuav tshwm sim tsis tu ncua.
Tseem Paub, yuav 12v AC LED khiav ntawm DC? Tsis muaj ib yam zoo li no AC LED . Muaj ib lub voj voog sab hauv uas tej zaum suav nrog tus choj txuas thiab qhov txwv tam sim no. Yog muaj, nws yuav ua haujlwm zoo ntawm 12 volts DC.
Ib yam li ntawd, LED teeb puas tuaj yeem khiav ntawm DC?
Feem ntau LED teeb siv tus choj rectifier uas tam sim ntawd hloov AC rau hauv DC , uas lub hwj chim converter ces tig mus rau hauv cov khoom tam sim no uas tus LEDs siv. Yog li ntawd, lawv yuav khiav ntawm DC ntawm qhov tsim nyog qhov hluav taws xob (tsis yog 12 volts).
LED teeb ua haujlwm nyob qhov twg?
Feem ntau, rau pem hauv ntej hluav taws xob ntawm ib LED yog nruab nrab ntawm 1.8 thiab 3.3 volts. Nws txawv ntawm cov xim LED . Liab LED Feem ntau poob 1.8 volts, tab sis txij li ob qho tib si hluav taws xob poob thiab teeb zaus nce nrog band sib txawv, xiav LED tuaj yeem poob ntawm 3 mus rau 3.3 volts.

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
