Hauv feem ntau daim ntawv thov LEDs yog tsav los ntawm ib DC fais fab mov. LEDs haus DC tam sim no los tsim lub 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.

Ib yam li ntawd, LED puas tuaj yeem ua haujlwm ntawm AC?

Khiav LEDs los ntawm ib AC muab. Hauv ntau daim ntawv thov, LEDs yog tsav los ntawm DC fais fab mov, tab sis AC muaj ntau yam zoo. Lynk Labs tau tsim thev naus laus zis uas tso cai rau LEDs tsav ncaj qha los ntawm ib qho AC muab. Ib txoj hauv kev tshiab yog los txhim kho AC -LEDs, uas ua tau khiav ncaj qha los ntawm ib qho AC fais fab mov.

dab tsi voltage ua LED teeb ua haujlwm? 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 lub teeb zaus nce nrog band sib txawv, xiav LED tuaj yeem poob ntawm 3 mus rau 3.3 volts.

Tsuas yog li ntawd, yog 12v LED qhov muag teev AC lossis DC?

Lwm yam Categories nyob rau hauv lub LED Qhov muag teev Qhov siab MR16 LEDs ua haujlwm ntawm 12 v , qhov no tuaj yeem yog 12 V AC ( hloov tam sim no ) los yog 12V DC tso (direct current). Yog tias qhov voltage yog AC , lawv yog tsim los ua hauj lwm nrog uas twb muaj lawm voltage halogen transformers. Ib LED tsav tsheb converts lub mains voltage AC nkag mus rau hauv a 12V DC tso tso zis.

Kuv yuav txuas 220v AC rau LED li cas?

Yuav Ua Li Cas

  1. Txuas dub anode ntawm diode rau qhov tsis zoo ntawm cov coj 0r raws li koj xav tau.
  2. txuas lub resistor rau qhov zoo ntawm LED lossis raws li koj xav tau tab sis circuits yuav tsum ua raws li cov cai.
  3. Txuas qhov pub dawb kawg ntawm diode thiab tus tiv thaiv rau tus txiv neej pins.as tau qhia hauv daim duab.
