LED Tsis tu ncua tam sim no fais fab mov
LED qhov hluav taws xob tas li tam sim no yog siv los muab lub zog rau LED teeb. Txij li cov tam sim no ntws los ntawm LEDs tau txais kev kuaj pom thiab tswj tau thaum lub sijhawm ua haujlwm ntawm lub zog, tsis tas yuav txhawj xeeb tias cov tam sim no dhau los ntawm cov LEDs thaum lub sijhawm fais fab tuag, thiab tsis tas yuav txhawj xeeb txog qhov luv-circuiting. lub load, rhuav tshem lub hwj chim mov.
Kev tsav tsheb tsis tu ncua tam sim no tuaj yeem zam qhov kev hloov pauv ntawm LED rau pem hauv ntej voltage thiab ua rau qhov hloov pauv tam sim no, thaum lub sijhawm tam sim no ua rau lub teeb ci ntawm LED ruaj khov, thiab nws kuj yog qhov yooj yim rau LED teeb lub Hoobkas kom paub meej cov khoom sib xws thaum siv ntau lawm. Yog li ntawd, ntau tus neeg tsim khoom tau paub meej txog qhov tseem ceeb ntawm lub zog tsav tsheb. Ntau lub tuam txhab LED luminaire tau tso tseg qhov tsis tu ncua voltage hom, thiab siv tus nqi qis dua qhov tam sim no hom los tsav lub LED luminaire.
Qee cov tuam txhab lag luam txhawj xeeb tias kev xaiv ntawm electrolytic capacitors ntawm lub hwj chim tsav tsheb yuav cuam tshuam rau lub neej ntawm lub hwj chim mov. Qhov tseeb, nws yog kev nkag siab yuam kev. Piv txwv li, yog tias siv 105 degrees, lub siab kub electrolytic capacitor nrog lub neej ntawm 8000 teev yuav raug txo los ntawm 10 degrees raws li lub neej expectancy ntawm electrolytic capacitors, thiab tus neeg tsav tsheb lub neej expectancy doubled, yog li nws muaj lub neej ua haujlwm ntawm 16,000 teev nyob rau hauv 95 degree ib puag ncig, lub neej ua haujlwm ntawm 32,000 teev nyob rau hauv ib puag ncig 85 degree, thiab lub neej ua haujlwm ntawm 64,000 teev hauv 75 degree ib puag ncig. Yog tias qhov ntsuas kub ua haujlwm tau qis dua, ces lub neej yuav ntev dua! Los ntawm qhov kev pom no, nws tsis muaj qhov cuam tshuam rau lub neej ntawm lub zog tsav ntev npaum li peb xaiv electrolytic capacitors zoo.
Kuj tseem muaj ib qho tseem ceeb uas tsim nyog rau kev saib xyuas rau cov tuam txhab teeb pom kev zoo LED: Raws li LED yuav tso tawm ntau cov cua sov thaum lub sij hawm ua hauj lwm, qhov kub thiab txias ntawm lub teeb yuav nce sai heev. Qhov siab dua lub zog LED, qhov ua kom sov ntau dua. Qhov nce ntawm qhov kub ntawm LED nti yuav ua rau kev ua haujlwm ntawm lub teeb-emitting ntaus ntawv. Kev hloov pauv thiab kev hloov pauv ntawm electro-optical efficiency yog attenuated, thiab txawm poob thaum qhov teeb meem loj. Raws li kev sim ntsuas, qhov luminous flux txo qis los ntawm 3% rau txhua txhua 5 degrees Celsius nce ntawm LED tus kheej kub. Yog li ntawd, LED teeb yuav tsum tau them sai sai rau lub tshav kub dissipation ntawm LED teeb qhov chaw nws tus kheej. Sim ua kom lub tshav kub dissipation ntawm LED teeb qhov chaw kom ntau li ntau tau, thiab sim txo qhov kub thiab txias ua haujlwm ntawm LED nws tus kheej. Yog tias muaj kev tso cai, nws yog qhov zoo dua los cais cov khoom siv hluav taws xob los ntawm qhov chaw teeb pom kev zoo. Nws tsis pom zoo kom nrhiav lub ntim me me qhov muag tsis pom kev thiab tsis quav ntsej txog kev ua haujlwm kub ntawm lub teeb thiab lub zog hluav taws xob.
