Dab tsi yog qhov yuam kev ntawm LED teeb?

Qhov tsis ua haujlwm ntawm LED teeb yog muab los ntawm qhov tsis ua haujlwm ntawm lub zog hluav taws xob thiab kev tsav tsheb, thiab qhov thib ob yog los ntawm qhov tsis ua haujlwm ntawm cov khoom siv LED nws tus kheej. Yog hais tias tus tsav Circuit Court muaj qhov tso zis voltage, thiab txoj hlua LED tsis tawm lub teeb, muaj ib txoj hlua LED ua txhaum. Feem ntau, qhov tsis ua hauj lwm ntawm LED teeb hlua yog qhov siab, yam tsawg kawg kuv tau ntsib ob peb zaug yog LED teeb hlua tsis ua haujlwm. Vim hais tias cov hlua LED teeb ua haujlwm nyob rau hauv series, yog tias muaj ib tus neeg tsis zoo nyob rau hauv nruab nrab ntawm qhov hlawv, nws yuav ua rau tag nrho tsis kaj. Kev kuaj pom ntawm cov hlua LED kuj tseem yooj yim, thiab tuaj yeem ntsuas nrog cov ntaub ntawv tsis kam lossis diode ntawm multimeter.

Feem ntau, kev puas tsuaj ntawm LED fais fab mov thiab tsav tsheb los ntawm overcurrent shock (EOS) ntawm cov khoom siv hluav taws xob thiab qhov qhib qhov hluav taws xob tsis ua haujlwm ntawm sab load. Kev cuam tshuam overcurrent ntawm cov khoom siv hluav taws xob feem ntau ua rau kev puas tsuaj ntawm lub nti tsav hauv lub voj voog tsav, thiab kev puas tsuaj ntawm cov khoom siv tsis zoo xws li cov capacitors. Qhov luv luv Circuit Court txhaum ntawm qhov kawg ntawm qhov kawg yuav ua rau lub overcurrent tsav ntawm tsav Circuit Court, thiab tsav Circuit Court tej zaum yuav muaj luv luv Circuit Court puas los yog overheating puas los ntawm luv Circuit Court txhaum.
