Qhov tseem ceeb ntawm tsav fais fab mov rau LED luminaires
Qee cov tuam txhab lag luam nce nyiaj tau los txhawm rau txo cov nqi los ntawm kev siv cov tsav tsheb tsis zoo. Yuav tsum muaj qhov teeb meem kev nyab xeeb uas tsis muaj noob nrog cov khoom pov thawj pov thawj muaj kev nyab xeeb no.
Qee lub chaw tsim khoom, txhawm rau txo cov nqi ntawm cov khoom, kev siv lub zog hluav taws xob tas li tsav LED, kuj tau coj los ntawm ntau lawm ntawm txhua qhov LED luminescence ci ci tsis zoo li qub, LEDs tsis tuaj yeem ua haujlwm zoo thiab muaj teeb meem ntau.
Qhov tam sim no qhov chaw tsav tsheb zoo LED tsav tsheb hom, kev siv cov tsav tam sim no tsis tu ncua, tsis tas yuav tsum muaj nyob rau hauv cov zis hluav taws xob series tam sim no txwv tsis kam, LED tam sim no ntws tsis cuam tshuam los ntawm cov khoom siv hluav taws xob sab nraud hloov pauv, kev hloov pauv kub, thiab LED parameter discrete, yog li txhawm rau tswj xyuas qhov tam sim no, muab kev ua si tag nrho rau ntau yam zoo ntawm LED.
Siv cov khoom siv hluav taws xob tas li tam sim no rau lub hwj chim LED luminaires, vim tias tam sim no ntws los ntawm LED tau raug kuaj pom thiab tswj tau thaum lub zog ua haujlwm, yog li koj tsis tas yuav txhawj xeeb txog qhov muaj qhov siab tam sim no los ntawm LED hauv lub sijhawm lub zog. , thiab koj tsis tas yuav txhawj txog lub load luv luv-circuiting lub hwj chim mov.
Siv lub tshuab tsav tam sim no, nws tuaj yeem zam qhov kev hloov pauv ntawm LED qhov zoo voltage thiab ua rau cov kev hloov pauv tam sim no, thaum lub sijhawm tam sim no ua rau LED ci ntsa iab, tab sis kuj pab txhawb LED luminaire Hoobkas los siv cov khoom loj los xyuas kom meej cov khoom sib xws, yog li ntau lub tuam txhab tau lees paub tag nrho. Qhov tseem ceeb ntawm kev tsav lub zog hluav taws xob, ntau lub tuam txhab LED teeb tau tso tseg qhov tsis tu ncua voltage hom, thiab xaiv tus nqi siab dua me ntsis tam sim no los tsav LED luminaires.
Qee cov tuam txhab lag luam txhawj xeeb tias lub zog hluav taws xob tsav lub rooj tsavxwm electrolyte capacitor yuav cuam tshuam rau lub neej ntawm lub zog hluav taws xob, yog qhov kev nkag siab yuam kev, piv txwv li, yog tias koj xaiv 105 degrees, lub neej ntawm 8000 teev ntawm qhov kub thiab txias electrolyte capacitor, raws li cov khoom siv electrolyte capacitor. Txoj kev kwv yees lub neej "txhua qhov txo qis ntawm 1 0 degrees, ob npaug ntawm lub neej", tom qab ntawd nws muaj lub neej ua haujlwm ntawm 16,000 teev hauv 95-degree ib puag ncig, lub neej ua haujlwm ntawm 32,000 teev hauv 85-degree ib puag ncig, thiab lub neej ua haujlwm ntawm 64,000 teev nyob rau hauv 75-degree ib puag ncig. Yog tias qhov ntsuas kub ua haujlwm qis dua, lub neej yuav ntev dua! Los ntawm qhov kev pom no, tsuav yog qhov kev xaiv ntawm cov khoom siv hluav taws xob zoo electrolyte capacitors ntawm lub neej ntawm kev tsav tsheb fais fab tsis cuam tshuam!
Kuj tseem muaj lub ntsiab lus tsim nyog ntawm LED luminaire cov lag luam ceeb toom: vim tias LED nyob rau hauv cov txheej txheem ntawm kev ua hauj lwm yuav tso tawm ib tug loj npaum li cas ntawm cov cua sov, thiaj li hais tias cov tub ntxhais kub kub nce sai heev, lub siab dua lub zog LED, lub zog cua sov ntau dua. Qhov nce ntawm LED nti kub yuav ua rau muaj kev hloov pauv hauv kev ua haujlwm ntawm lub teeb emitting li thiab electro-optical conversion efficiency attenuation, loj los yog txawm tsis ua hauj lwm, raws li kev sim qhia tau hais tias: LED nws tus kheej kub nce ntawm 5 degrees Celsius, lub teeb txaus. yog txo los ntawm 3%, yog li LED luminaires yuav tsum tau them sai sai rau lub teeb ci LED nws tus kheej txias ua hauj lwm, nyob rau hauv cov ntaub ntawv ntawm muaj peev xwm mus maximize lub txias cheeb tsam ntawm lub LED lub teeb qhov chaw nws tus kheej, kom deb li deb raws li qhov ua tau kom txo tau qhov kub thiab txias ntawm LED. nws tus kheej, yog tias muaj kev tso cai, lub hwj huam mov yog cais los ntawm lub teeb qhov chaw, nws tsis tsim nyog mus nrhiav qhov me me thiab tsis quav ntsej qhov kub thiab txias ntawm cov khoom siv hluav taws xob.
