Cov ntaub ntawv siv nyob rau hauv LED teeb muaj ntau yam tseem ceeb, feem ntau nrog rau cov nti, substrate, encapsulation cov ntaub ntawv, lub teeb, thiab vaj tse. Hauv qab no yog cov lus qhia ntxaws txog cov ntaub ntawv no.
Ua ntej, lub nti yog lub teeb tseem ceeb -emitting lub teeb ntawm LED teeb. Nws feem ntau yog ua los ntawm monocrystalline silicon, ua tiav siv cov txheej txheem semiconductor.
Monocrystalline silicon muaj cov khoom siv hluav taws xob zoo heev, ua haujlwm zoo hloov hluav taws xob rau hauv lub teeb lub zog, uas yog qhov tseem ceeb rau LED lub teeb -emitting muaj nuj nqi. Qhov zoo ntawm cov nti ncaj qha txiav txim siab cov cim tseem ceeb xws li LED lub luminous efficiency, xim zoo, thiab lifespan.
Qhov thib ob, lub substrate txhawb nqa lub nti thiab muab cov cua sov dissipation thiab hluav taws xob sib txuas. Cov khoom siv substrate muaj xws li hlau substrates (xws li txhuas thiab tooj liab substrates) thiab ceramic substrates. Hlau substrates muaj zoo thermal conductivity, sai sai dissipating lub tshav kub generated los ntawm lub nti, txo nws cov kev khiav hauj lwm kub, thiab yog li txhim kho lub LED stability thiab lifespan. Ceramic substrates muab cov rwb thaiv tsev ntau dua thiab siab -kub tsis kam, ua rau lawv tsim nyog rau cov ntawv thov uas muaj kev ruaj ntseg hluav taws xob siab.
Cov khoom siv encapsulation yog qhov tseem ceeb rau kev tiv thaiv cov nti thiab substrate thiab ua kom lub teeb tso zis. Cov ntaub ntawv encapsulation muaj xws li epoxy resin thiab silicone. Epoxy resin encapsulation muaj qhov zoo xws li tus nqi qis thiab kev ua haujlwm yooj yim, tab sis nws qhov siab - kub tsis kam thiab UV tsis kam yog qhov tsis zoo. Silicone encapsulation, ntawm qhov tod tes, muab qhov zoo dua siab -kub tsis kam, UV tsis kam, thiab kev ua haujlwm zoo tshaj plaws, kev txhim kho lub luminous efficiency thiab xim zoo ntawm LED teeb.
Lub teeb yog ib qho tseem ceeb sab nrauv ntawm lub teeb ci LED, ua los ntawm ntau yam ntaub ntawv, xws li acrylic, iav, thiab PC (polycarbonate). Acrylic lampshades muab lub teeb pom kev zoo, lub teeb yuag, thiab yooj yim ntawm kev ua, ua rau lawv siv dav hauv ntau yam LED teeb pom kev zoo. Iav lampshades muab lub teeb xa hluav taws xob ntau dua thiab huab cua zoo dua, tab sis hnyav dua thiab kim dua rau kev ua haujlwm. PC lampshades muaj kev cuam tshuam zoo heev thiab ua haujlwm kub, ua rau lawv tsim nyog rau cov ntawv thov uas muaj kev nyab xeeb siab.
Thaum kawg, lub plhaub sab nrauv muab kev txhawb nqa tag nrho thiab kev tiv thaiv rau lub teeb ci LED, feem ntau yog ua los ntawm cov hlau (xws li txhuas lossis hlau) lossis yas. Cov plhaub hlau muab cov cua sov zoo dua thiab cov qauv tsim muaj zog, txhim kho kev ruaj ntseg thiab kev ua neej nyob ntawm LED teeb. Cov plhaub yas muab cov nqi qis, lub teeb yuag, thiab kev ua haujlwm yooj yim, ua rau lawv tsim nyog rau cov ntawv thov nrog cov nqi siab.
