Hauv ntau daim ntawv thov LEDs yog tsav los ntawm DC fais fab mov. LEDs siv DC tam sim no los tsim lub teeb; nrog AC tam sim no LED yuav tsuas yog teeb thaum cov dej ntws tam sim no nyob hauv qhov 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 rau qhov pom kev tas li.

Kuj paub, puas yuav 12v LED khiav ntawm AC?

Rau khiav ib LED -based cov khoom siv los ntawm cov khoom siv hluav taws xob (piv txwv li 120 V AC ) xav tau cov khoom siv hluav taws xob nruab nrab ntawm cov khoom siv thiab cov cuab yeej siv lawv tus kheej los muab DC voltage (piv txwv li 12 V DC) muaj peev xwm tsav tau ntau yam LEDs . Ib txoj hauv kev tshiab yog los txhim kho AC - LEDs , uas tau khiav ncaj qha los ntawm ib qho AC fais fab mov.

LEDs tam sim no xav tau dab tsi? LEDs feem ntau xav tau 10 txog 20mA, cov ntawv qhia rau LED yuav nthuav qhia qhov no nrog rau qhov poob qis rau pem hauv ntej. Piv txwv li ib qho ultra ci xiav LED nrog lub roj teeb 9V muaj lub zog rau pem hauv ntej ntawm 3.2V thiab raug tam sim no ntawm 20mA.

Tom qab ntawd, lo lus nug yog, LED qhov muag puas tuaj yeem ua haujlwm ntawm 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 . Lawv rectifier muaj cov kauj ruam nqes hluav taws xob uas tau tsis ua haujlwm rau DC.

Koj puas tuaj yeem siv cov qij LED hauv toj roob hauv pes teeb pom kev zoo?

Kho koj lub vaj uas twb muaj lawm teeb nrog LED teeb yuav xa plaub yeej: Yooj yim ntawm installation: Txawm tias low voltage toj roob hauv pes teeb fixtures yog qhov yooj yim zoo nkauj los hloov, koj yuav tsis xav tau thaum kho dua koj cov uas twb muaj lawm rau LED qhov muag teev.
