Dab tsi yog qhov cuam tshuam rau AC-dawb LED Teeb Decay?

1. AC-dawb LED nws tus kheej qhov teeb meem zoo: 1. LED nti siv tsis zoo, thiab qhov ci ntsa iab tau nrawm dua. 2. Muaj qhov tsis xws luag hauv cov txheej txheem tsim khoom. Lub tshav kub dissipation ntawm LED nti tsis tuaj yeem ua tau zoo los ntawm tus PIN ko taw, uas ua rau qhov kub ntawm cov nti LED ntau dhau ua rau lub zog ntawm cov nti. 2. Siam LED yog ib tug tas mus li kwj tsav. Qee cov LEDs siv cov tsav tsheb hluav taws xob los ua kom LED attenuation. 2. Tus tsav tsheb tam sim no ntau dua li qhov ntsuas tus neeg tsav tsheb. Qhov tseeb, muaj ntau yam laj thawj rau lub teeb lwj ntawm AC-dawb LED khoom. Qhov tseem ceeb yog qhov teeb meem ntawm tshav kub. Txawm hais tias muaj ntau lub tuam txhab tsis them nyiaj tshwj xeeb rau cov teeb meem ntawm cov cua kub dissipation, cov khoom siv LED thib ob yuav siv tau ntev. Cov khoom siv LED uas tsom rau cov cua sov dissipation yuav tsum siab. Lub thermal tsis kam ntawm LED nti nws tus kheej, qhov cuam tshuam ntawm cov kua nplaum nyiaj, cov nyhuv thermal dissipation ntawm lub substrate, thiab nam ntawm colloid thiab golden kab kuj muaj feem xyuam rau lub teeb lwj. Peb yam cuam tshuam rau lub teeb pom kev zoo ntawm cov teeb pom kev zoo ntawm LED teeb, ua ntej ntawm txhua yam, xaiv lub teeb dawb LED zoo li cas. Tsis tas li ntawd xwb. Qhov zoo ntawm AC-dawb LED tuaj yeem hais tias yog qhov tseem ceeb heev. Piv txwv li, tib yam yog sawv cev los ntawm cov nti ntawm cov nti ntawm cov nti 14mil, thiab cov teeb pom kev zoo LED tau ntim los ntawm cov pos hniav hauv qab thiab cov kua nplaum dawb thiab cov kua nplaum uas ua los ntawm cov epoxy resin zoo tib yam tau teeb nyob rau hauv ib puag ncig 30-degree. Tom qab ntau txhiab teev, cov ntaub ntawv attenuated yog 70% ntawm lub teeb lwj; Yog tias D hom D qis-decaying kua nplaum yog encapsulated, nyob rau hauv tib lub aging ib puag ncig, lub 1,000-teev lub teeb lwj yog 45%; , 1,000-teev lub teeb lwj yog 12%; yog tias qeb B yog encapsulated nyob rau hauv cov kua nplaum uas tsis tshua muaj, nyob rau hauv tib lub aging ib puag ncig, phav phav teev ntawm lub teeb lwj ntawm -3%; Yog tias Class A cov kua nplaum qis qis, nyob rau tib qhov chaw laus, ntau txhiab teev ntawm lub teeb, ntau txhiab teev ntawm lub teeb Dechat yog -6%. Qhov thib ob, qhov chaw ua haujlwm kub ntawm LED teeb hlaws. Raws li cov ntaub ntawv thaum ib qho LED dawb lub teeb yog laus, yog tias LED dawb lub teeb tsuas muaj ib lub teeb pom kev zoo, tib lub sij hawm, qhov kub ntawm ib puag ncig nws nyob yog 30 degrees, ces lub bracket kub ntawm ib qho AC-free LED. tsis tsav LED ua haujlwm. Tsis tas li ntawd xwb. Lub sijhawm no, lub neej ntawm LED no yuav zoo tagnrho. Yog tias muaj 100 LED lub teeb dawb rau tib lub sijhawm ua haujlwm, lub sijhawm nruab nrab ntawm lawv tsuas yog 11.4 hli, tom qab ntawd qhov kub thiab txias ntawm lub bracket kub ntawm LED lub teeb dawb nyob ib ncig ntawm lub teeb pawg yuav tsis tshaj 45 degrees, tab sis qhov nruab nrab. ntawm lub teeb pawg yog nyob rau hauv nruab nrab ntawm lub teeb pawg. Cov LED dawb lub teeb yuav ncav cuag 65 degrees kub. Lub sijhawm no, LED teeb hlaws yog kev sim. Tom qab ntawd, cov teeb ci LED dawb sib sau ua ke hauv qhov kev xav yuav theoretically ceev lub teeb sai dua, thiab LED dawb lub teeb nyob ib ncig ntawm lub teeb yuav qeeb dua. Txawm li cas los xij, txhua tus yuav tsum paub tias LED ntshai tshav kub. Qhov kub thiab txias dua, LED lub neej luv dua, qhov kub thiab txias, thiab LED lub neej ntev dua. Qhov ua haujlwm kub ntawm LED zoo tagnrho yog qhov tseeb ntawm 5 lossis xoom degrees tsis zoo. Tab sis qhov no yeej tsis yooj yim sua. Yog li ntawd, tom qab peb nkag siab txog qhov ua haujlwm zoo tshaj plaws ntawm LED teeb hlaws, peb yuav tsum ntxiv dag zog rau kev ua haujlwm ntawm cov cua sov thiab cov cua sov dissipation thaum tsim cov teeb ntau li ntau tau thaum tsim cov teeb ntau li ntau tau. Xijpeem, qhov kub thiab txias, qhov ntev ntawm LED lub neej ncua. Thib peb, AC-dawb LED ua haujlwm hluav taws xob tsim qauv. LED-sab teeb qhov chaw LED txhaj tshuaj molding module LED teeb sawb LED waterproof irrigation kua nplaum module Hongyan cab triple -in -cab. Peb - ib qho khoom siv hnyav ua haujlwm Raws li kev sim ua tiav, qhov qis dua ntawm LED lub teeb dawb, qhov me dua cov cua sov tawm, qhov me me, Qhov tseeb, qhov me dua qhov ci. Raws li kev tshawb fawb, kev tsim ntawm LED hnub ci teeb pom kev zoo Circuit Court, tus tsav tsheb tam sim no ntawm LED feem ntau tsuas yog 5-10mA; ntau lub teeb siv hauv cov teeb, xws li ntau tshaj 500 lossis ntau dua Thiab feem ntau nrov LED daim ntawv thov teeb pom kev zoo tsav tam sim no tsuas yog 15-18mA, thiab ob peb tus neeg tsim cov tam sim no ntau tshaj 20mA. Cov txiaj ntsig kev sim kuj pom tau tias nyob rau hauv tus neeg tsav tsheb tam sim no ntawm 14mA, thiab lub hau tsis tau tso cua, huab cua kub hauv nws mus txog 71 degrees, cov khoom qis qis, 1,000-teev lub teeb lwj, 2000 teev ntawm lub teeb lwj ntawm 3% mus rau 3%. , 3% decaying yog 3%. Qhov no qhia tau hais tias qhov tsis tshua muaj hluav taws xob LED lub teeb dawb no tau mus txog nws qhov kev txwv zoo tshaj plaws hauv ib puag ncig zoo li no. Txawm nws loj npaum li cas los, nws yog kev puas tsuaj rau nws. Vim tias lub rooj tsav xwm kev laus rau kev laus tsis muaj cua sov dissipation muaj nuj nqi, cov cua sov tsim los ntawm AC-free LED yog qhov yooj yim tsis tuaj yeem xa mus rau sab nraud. ( 1 Khaulee 3: 1 - 5) Tej no. Cov huab cua kub hauv lub vaj huam sib luag qub tau mus txog qhov kub ntawm 101 degrees. Qhov kub ntawm lub hau ntawm lub vaj huam sib luag qub tsuas yog 53 degrees, uas yog kaum ob degrees. Qhov no qhia tau hais tias lub hau yas tsim ib txwm tsis muaj kev ua haujlwm ntawm kev ua cua sov thiab cua sov dissipation. Tab sis nyob rau hauv kev tsim lub teeb dav dav, xav txog kev ua haujlwm ntawm kev ua cua sov thiab cua sov dissipation. Yog li ntawd, nyob rau hauv cov ntsiab lus, tus tsim ntawm kev ua hauj lwm hluav taws xob tsis ua hauj lwm ntawm LED teeb hlaws yuav tsum tau raws li qhov tseeb qhov teeb meem. Yog hais tias lub tshav kub-conducting tshav kub dissipation muaj nuj nqi ntawm lub teeb yog zoo heev, nws yog tsim nyog los ua kom lub zog tsav tam sim no ntawm LED dawb teeb, vim hais tias cov LED teeb hlaws dai ua hauj lwm tsim. Cov cua sov tuaj yeem raug xa tawm mus rau sab nraud, thiab tsis muaj kev puas tsuaj rau LED, uas yog kev saib xyuas ntawm LED. Ntawm qhov tsis sib xws, yog tias qhov hluav taws kub-conducting heat dissipation muaj nuj nqi ntawm lub teeb yog sloppy, lub Circuit Court yog tsim me me, kom nws txo qis cua sov tawm ntawm nws.
