Dab tsi yog qhov teeb meem ntawm qhov kub thiab txias sab nraum zoov LED puv xim zaub? Sab nraum zoov tag nrho-xim LED zaub yog heev picky txog qhov kub thiab txias ib puag ncig. Hauv kev xav, chav tsev kub nyob ib ncig ntawm 25 degrees Celsius ua haujlwm zoo tshaj plaws. Tab sis qhov tseeb, qhov kub ntawm sab nraum zoov LED puv xim zaub screen yog qhov nyuaj heev hauv daim ntawv thov, thiab qhov kub siab tshaj plaws nyob rau lub caij ntuj sov tuaj yeem ncav cuag 60 degree. Qhov ntsuas kub qis tshaj plaws nyob rau lub caij ntuj no tuaj yeem qis dua -20 degree . Kub kub yuav ua rau tag nrho cov kev puas tsuaj rau sab nraum zoov puv xim LED zaub. Nyob rau sab nraum zoov puv xim LED zaub, lub neej ntev yuav tshwm sim thaum lub teeb txo qis, uas yog hais tias, qhov ci ntsa iab yuav qis dua thiab qis dua raws li lub sijhawm dhau mus, mus txog thaum nws tawm mus. Nyob rau hauv ib txwm muaj, lub luminous flux lwj lub sij hawm ntawm ib tug sab nraum zoov tag nrho-xim LED zaub hais txog nws lifespan.
Sab nraum zoov puv xim coj zaub
Nyob rau hauv ib txwm muaj xwm txheej, lub teeb attenuation ntawm sab nraum zoov LED puv xim cov ntxaij vab tshaus yog tshwm sim los ntawm cov hauv qab no:
Thaum qhov kub thiab txias, qhov tsis xws luag hauv cov khoom siv nti ntawm sab nraum zoov LED cov xim puv xim yuav nrawm nrawm thiab sib npaug kom txog thaum nws nkag mus rau thaj chaw teeb pom kev zoo, yog li tsim ntau qhov chaw tsis muaj hluav taws xob sib xyaw, uas cuam tshuam rau lub luminous efficiency. ntawm sab nraum zoov puv xim LED zaub. Tsis tas li ntawd, nyob rau hauv qhov kub thiab txias, qhov tsis xws luag hauv cov khoom siv thiab cov impurities nrawm nrawm los ntawm kev sib tshuam thiab lub rooj tsav xwm hluav taws xob kuj tseem yuav nkag mus rau thaj chaw teeb pom kev zoo, yog li tsim kom muaj ntau lub zog sib sib zog nqus, thiab tseem yuav ua kom lub teeb attenuation. ntawm sab nraum zoov LED puv xim zaub li. Pob tshab epoxy resin undergoes denaturation thiab yellowing ntawm qhov kub thiab txias, uas yuav cuam tshuam rau nws permeability, thiab nyob rau hauv qhov kub thiab txias, cov txheej txheem no tshwm sim sai dua, uas yog lub ntsiab yog vim li cas rau lub teeb attenuation ntawm sab nraum zoov LED puv xim zaub. Vim yog qhov hnyav ntawm phosphors nyob rau hauv qhov kub thiab txias, qhov attenuation ntawm phosphors rau sab nraum zoov LED puv xim zaub cov ntxaij vab tshaus kuj yog lub ntsiab tseem ceeb uas cuam tshuam rau lub teeb attenuation ntawm LED cov ntxaij vab tshaus.
