Cov puv xim LED zaub yog keej heev txog qhov ntsuas kub ambient. Raws li kev xav, kev ua haujlwm zoo yog qhov zoo tshaj plaws ntawm chav tsev kub txog 25 ° C. Tab sis qhov tseeb, hauv kev siv hluav taws xob sab nraum zoov LED cov lus, qhov ntsuas cua yog qhov nyuaj heev.
Qhov sov siab tshaj plaws hauv lub caij ntuj sov yuav siab tshaj 60 ° C, thiab qhov kub tsawg kawg nyob rau lub caij ntuj no yuav qis dua-20 ° C. Qhov ua hauj lwm kev ua haujlwm thiab kev ua haujlwm ntawm LED thiab IC yog qhov tsis sib xws, lub ci ci yuav tsis sib thooj, thiab txhua yam ntawm lub vijtsam yuav pauv. Hauv qhov kub thiab txias txawv, qhov pom kev zoo dua thiab poob ntawm xim liab, ntsuab, thiab xiav muaj qhov sib txawv.
Ntawm 25 ° C, qhov dawb tshuav yog qhov qub, tab sis ntawm 60 ° C, qhov ci ci ntawm peb lub xim ntawm LED yog txhua qhov poob qis, thiab nws cov nqi attenuation tsis sib xws, yuav ua rau tag nrho lub vijtsam hloov chaw poob thiab xim nrum tshwm sim, thiab ces qhov zoo tshaj ntawm tag nrho cov zaub LED yuav poob qis.
