Kev tshuaj xyuas ntawm qhov ua rau LED teeb lwj
Raws li hom tshiab ntawm teeb pom kev zoo ntsuab, LED teeb yog txuag hluav taws xob, ib puag ncig tus phooj ywg thiab nyob ntev. Lub lag luam muaj peev xwm loj heev. Txawm li cas los xij, qhov teeb meem ntawm LED teeb lwj yog lwm qhov teeb meem uas LED teeb yuav tsum tau ntsib. Tsis muaj kev cuam tshuam lub teeb lwj, cuam tshuam rau kev siv cov teeb ci LED.
Rau lub sijhawm tam sim no, lub teeb tawg ntawm cov LEDs dawb ntawm lub khw yuav yog ib qho teeb meem saum toj kawg nkaus rau pej xeem teeb pom kev zoo. Feem ntau, muaj ob yam tseem ceeb rau lub teeb lwj ntawm LEDs:
Ua ntejly, qhov zoo ntawm LED khoom lawv tus kheej:
1. LED nti siv tsis zoo, thiab qhov ci ntsa iab yog attenuated sai.
2, cov txheej txheem ntau lawm yog qhov tsis zoo, LED nti hluav taws xob tsis tuaj yeem raug xa tawm zoo los ntawm lub dab dej kub, ua rau lub siab kub ntawm LED nti ua rau lub nti attenuation.
Thib obly, musntawmtej yam kev mob:
1. Lub LED yog tsav los ntawm qhov tam sim no tsis tu ncua, thiab qee qhov ntawm cov LEDs tau tsav los ntawm qhov hluav taws xob ua rau lub LED yuav tsum attenuated.
2. Lub zog tsav tam sim no ntau dua li qhov ntsuas tsav.
Qhov tseeb, muaj ntau yam laj thawj rau lub teeb lwj ntawm LED cov khoom. Qhov teeb meem tseem ceeb tshaj plaws yog qhov teeb meem kub. Txawm hais tias ntau lub tuam txhab tsis tau them nyiaj tshwj xeeb rau cov cua kub dissipation hauv cov khoom lag luam theem nrab, kev siv cov khoom siv LED no mus ntev yuav muaj qhov sib zog ntawm lub teeb. Cov khoom cua txias LED yuav tsum siab. Lub thermal tsis kam ntawm LED nti nws tus kheej thiab lub tshav kub dissipation nyhuv ntawm lub substrate kuj muaj feem xyuam rau lub teeb lwj.
Peb qhov cuam tshuam LEDs Teeb zoo lub teeb fade factor
Ua ntej tshaj plaws, kev xaiv ntawm LED teeb hlaws dai.
Qhov zoo ntawm LED teeb hlaws tuaj yeem hais tias yog qhov tseem ceeb heev. LED chips ntawm ntau lawm technologies muaj sib txawv speeds ntawm lub teeb lwj. Piv txwv li, ntau lub tuam txhab tsis tau yuav cov khoom tseem ceeb tuaj txawv teb chaws. OAK yuav Asmeskas thawj CREE LED teeb hlaws. Lub tshuab ntim tag nrho yog siab dua li lwm cov LED teeb hlaws hauv tib lub lag luam, uas muaj txiaj ntsig zoo hauv kev ua haujlwm ntawm lub teeb thiab kub tsis kam.
Thib obly, LED teebua haujlwmkub.
Raws li CREE LED teeb hlaws cov ntaub ntawv kev laus, thaum lub teeb ci LED hlaws ua haujlwm, qhov kub thiab txias yog 30 degrees, tom qab ntawd qhov kev ua haujlwm kub ntawm ib lub teeb ci LED hlaws yog 60-70 degrees. Qhov no yog qhov zoo tshaj plaws ua haujlwm kub rau kev siv mus ntev.
LED ntshai tshav kub, qhov kub ntawm LED teeb hlaws, lub neej luv ntawm LED, qhov kub thiab txias ntawm LED teeb hlaws, lub neej ntev ntawm LED. Yog li ntawd, thaum tsim lub luminaire, kev ua haujlwm ntawm cov cua sov thiab cov cua kub dissipation yog txhim kho kom ntev lub neej ntawm LED teeb.
Thib peb, kev ua haujlwm hluav taws xob tsis zoo ntawm LED teeb hlaws yog tsim.
Raws li kev sim, qhov qis dua tam sim no ntawm LED teeb hlaws, qhov me me ntawm cov cua sov tawm, thiab qhov me dua qhov ci.
Hauv cov ntsiab lus , tus tsim ntawm kev ua haujlwm hluav taws xob tsis zoo ntawm LED teeb hlaws yuav tsum ua raws li qhov xwm txheej tiag tiag. Yog hais tias lub tshav kub conduction thiab tshav kub dissipation muaj nuj nqi ntawm lub teeb yog zoo heev, lub tshav kub generated los ntawm lub lag luam ntawm lub LED teeb hlaws yuav ncaj qha exported rau sab nraud yam tsis muaj kev puas tsuaj rau lub LED.
