Cov lus teb yuav tsum yog qhov voltage faib los ntawm qhov voltage poob ntawm 1 LED. Yog li yog koj qhov chaw yog 12 v ua ,a koj LEDs muaj qhov poob qis ntawm 3.5, 12 / 3.5v, muab koj 3 LEDs . Yog lub forward voltage poob ntawm lub LEDs yog raws nraim 3 volts, koj 'd yuav tau tsav 4 ntawm lawv, thiab yuav tsis xav tau kev txwv tam sim no.
Kuj paub, muaj pes tsawg LEDs koj tuaj yeem ua hauv koob?
Koj tuaj yeem tso 3 coj nyob rau hauv series nrog limiting resistor. Tam sim no tag nrho los ntawm cov leds thiab tus tiv thaiv yuav yog 20mA. Koj tuaj yeem siv ntau ceg ntawm 3 leds ib raws li cov khoom siv hluav taws xob muaj zog.
Ib yam nkaus, txhua tus LED 12v? Yuav luag tag nrho LEDs yog 12 v , thiab yog li yuav tsum txuas nrog a 12 v fais fab mov thiab tsis txhob ntsaws ncaj qha rau hauv qhov hluav taws xob lossis 120V lub zog siv.
Kuj Paub, pes tsawg amps siv 12 volt LED teeb?
Piv txwv li, 120V LED qhov system yuav rub 1 Amp hauv 120 Watt system, thaum a 12V LED teeb qhov system yuav tsum rub 10 Amps kom lub zog tib yam 120 Watt system.
Yuav tsum LEDs yuav wired nyob rau hauv series los yog parallel?
Hauv ntej, thaiv nyob rau hauv series faib cov hwj huam tag nrho ntawm cov LEDs . Kev xaim lawv hauv thaum uas tig mus txhais tau tias txhua tus LED yuav tau txais tag nrho cov voltage uas lub hwj huam mov yog outputting. Yog muaj ntau LEDs txuas nrog lub roj teeb, lawv yuav kos ntau tam sim no los ntawm lub roj teeb thiab ntws nws txawm tias sai dua.

Muaj pes tsawg LEDs nyob rau hauv ib tug series 12v?
Yog li, lub roj teeb 12V txuas mus rau plaub 3V LEDs hauv kab ntawv yuav faib 3V rau txhua lub LEDs. Tab sis tib lub roj teeb 12V txuas rau plaub 3V LEDs ua ke yuav xa tag nrho 12V rau txhua LED - txaus kom hlawv cov LEDs kom paub meej! Kev sib txuas ntawm LEDs nyob rau hauv parallel tso cai rau ntau LEDs sib koom tsuas yog ib qho hluav taws xob qis hluav taws xob
