Yog li, 12V roj teeb xaim rau plaub 3V LEDs hauv koob yuav faib 3V rau txhua tus 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.
Hais txog qhov no, pes tsawg LEDs tuaj yeem khiav ntawm 12v?
Yog li yog tias koj lub hauv paus yog 12v, thiab koj cov LEDs muaj qhov poob qis ntawm 3.5, 12/3.5v, muab rau koj 3 LEDs . Yog tias qhov kev poob qis rau pem hauv ntej ntawm LEDs yog qhov tseeb 3 volts, koj tuaj yeem tuaj yeem tsav 4 ntawm lawv, thiab yuav tsis xav tau qhov txwv tam sim no.
Tsis tas li ntawd, puas yog tag nrho 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.
Ib sab saum toj, pes tsawg LEDs koj tuaj yeem khiav hauv series?
Koj tuaj yeem tso 3 leds ib 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.
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 koj tuaj yeem khiav tawm 12v?
Cov lus teb yuav tsum yog qhov hluav taws xob faib los ntawm qhov poob qis ntawm 1 LED. Yog li yog tias koj lub hauv paus yog 12v, thiab koj cov LEDs muaj qhov poob qis ntawm 3.5, 12/3.5v, muab rau koj 3 LEDs. Yog hais tias lub pem hauv ntej voltage poob ntawm LEDs yog raws nraim 3 volts, koj yuav tau tsav 4 ntawm lawv, thiab yuav tsis xav tau ib tug tam sim no limiting resistor
