Cov tsav tsheb tsis tu ncua LED tam sim no yog tsim los rau cov qauv tsim tawm ntawm cov tso zis ntsuas thiab cov tso zis hluav taws xob tam sim no (mA). Cov LEDs uas tau raug ntsuas kom ua haujlwm ntawm lub tshuab tsav tsheb tsis tu ncua yuav tsum tau muaj cov khoom tsim tawm tam sim no feem ntau tau teev tseg hauv milliamps (mA) lossis amps (A). Cov tsav tsheb sib txawv qhov ntsuas hluav taws xob nyob ntawm hluav taws xob hluav taws xob uas tso cai rau tam sim no kom nyob twj ywm thoob plaws hauv LED system.Higher kev ntaus nqi tam sim no ua rau lub LED ci ntsa iab dua, tab sis yog tias tsis tau tswj, LED yuav kos ntau dua tam sim no tshaj li nws tau ntsuas rau.Thermal Runaway hais txog ntau dhau tam sim no dhau ntawm LEDs qhov siab tshaj plaws tsav tam sim no uas ua rau muaj hluav taws xob tsawg dua LED lub neej thiab ua ntej hlawv tawm vim qhov kub nce. Tus tsav tsheb tsis tu ncua tam sim no yog qhov zoo tshaj plaws rau kev tsav tsheb siab zog LEDs vim nws tswj lub teeb ci ntsa iab nyob thoob txhua qhov chaw hauv LED.
