Lub teeb tso zis ntawm LED yog ncaj qha proportional rau pem hauv ntej tam sim no ntws los ntawm nws cov semiconductor hlws ris. Yog hais tias tam sim no fluctuates nyob rau hauv loj teev, yog li ntawd yog lub teeb tso zis. Yog li ntawd, kom tswj tau qhov ci ntsa iab tas li LEDs yuav tsum tau tsav los ntawm kev tswj hwm DC tam sim no. Tsis tas li ntawd, LED modules txuas nrog nyob rau hauv parallel tuaj yeem ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav vim muaj peev xwm hloov pauv tam sim no yog tias qhov tam sim no tsis raug tswj xyuas. Ib qho luv luv lossis ib qho qhib Circuit Court ntawm ib qho LED modules yuav nthuav tawm cov LED modules ntxiv rau qhov hluav taws xob dhau kev ntxhov siab (EOS) vim lawv raug yuam kom tswj hwm qhov loj ntawm tam sim no. Kev khiav hauj lwm LEDs ntawm lub siab tsav tam sim no tuaj yeem ua rau tsis muaj kev puas tsuaj rau LEDs. LEDs hloov tsuas yog nyob ib ncig ntawm 50 feem pua ntawm lub zog rau hauv lub teeb thiab lub zog ntxiv yog dissipated li cua sov. Kev ua haujlwm siab tsav tam sim no ua rau kev sib tshuam kub nce siab tshaj qhov siab tshaj plaws, uas ua kom cov txheej txheem degradation ntawm cov khoom siv hauv cov pob LED, xws li phosphor lossis encapsulate.
Txhawm rau tiv thaiv kev puas tsuaj los ntawm kev tsav tsheb dhau mus, ib qho LED module uas txuas rau lub zog hluav taws xob tas li yuav muaj cov cuab yeej txwv tam sim no. Tej zaum nws yuav yog ib tug resistor, ib tug tas li tam sim no resistor (CCR), los yog ib tug active tam sim no regulator circuit. Cov limiters tam sim no tseem muab qhov tseeb tam sim no sib koom ntawm cov zis thiab ua kom lub teeb pom kev zoo sib xws thoob plaws LED modules.
