Dab tsi yog "COB" LEDs thiab Vim Li Cas Lawv Tseem Ceeb?
Lub ntsiab lus "COB" sawv cev rau chip-on-board LEDs.
Lub sij hawm "Chip-on-Board" (feem ntau abbreviated li "COB") piav qhia txog cov txheej txheem ntawm tsim LED arrays los ntawm mounting ib tug liab qab LED nti nyob rau hauv kev sib cuag nrog ib tug substrate (xws li silicon carbide los yog sapphire, piv txwv li). Thaum muab piv rau cov khoom siv hluav taws xob ntau dua qub, xws li Surface Mounted Device ("SMD") LEDs thiab Dual In-line Package ("DIP") LEDs, Chip-on-Board (COB) LEDs muaj ntau yam txiaj ntsig. Ua ntej thiab qhov tseem ceeb tshaj plaws, COB thev naus laus zis ua kom muaj kev ntim ntau ntxiv ntawm LED array, tseem hu ua "lumen ntom" los ntawm cov neeg ua haujlwm hauv kev lag luam teeb pom kev zoo. Yog tias peb piv COB LED thev naus laus zis rau DIP LED thev naus laus zis thiab SMD LED thev naus laus zis, peb tuaj yeem pom tias COB LED thev naus laus zis ua rau 38 npaug ntau dua LEDs thaum siv rau 10mm x 10mm square array, whereas SMD LED technology ua rau 8.5 npaug ntau LEDs. Raws li qhov tshwm sim, lub teeb uas tsim los ntawm kev siv zog ntau dua thiab sib faib ntau dua. Hloov pauv, los ntawm kev siv COB LED thev naus laus zis, nws muaj peev xwm txo qis cov hneev taw nrog rau kev siv lub zog ntawm LED array thaum tuav tib theem ntawm lub teeb tsim. Piv txwv li, raws li kev sib piv rau SMD lossis DIP LED array nrog tib lub lumen tso zis, COB LED array nrog 500 lumens tuaj yeem ua tau ntau dua thiab siv zog tsawg dua.
Qhov tseeb tias COB cov cuab yeej tsuas muaj ib lub voj voog thiab ob qhov kev sib txuas rau tag nrho cov nti thaum muaj pes tsawg tus diodes ntawm lawv tseem yog lwm qhov txiaj ntsig tseem ceeb ntawm kev siv COB LED thev naus laus zis. Qhov seem ntawm cov khoom siv LED yog yooj yim los ntawm qhov kev tsim ib lub voj voog, uas yog ywj siab ntawm cov diodes muaj nyob rau hauv nti.
Cov hauv qab no yog qee qhov txiaj ntsig uas Chip-on-Board LED arrays muab:
Compactness raws li qhov tshwm sim ntawm cov nti diminutive loj High-Intensity, tshwj xeeb tshaj yog thaum ua hauj lwm nyob ze
High degree ntawm uniformity, txawm tias thaum ua hauj lwm nyob ze ze.
Tsim Simplicity, raws li tsuas yog xav tau rau ib lub voj voog thiab ob qhov kev sib txuas los siv Superior Thermal Performance, ua rau lub neej zoo dua, kev ruaj ntseg, thiab kev cia siab.
Vim li cas COB LEDs yog qhov tseem ceeb thaum siv lub zog los ntawm lub roj teeb?
Thaum tsim lub teeb pom kev zoo uas siv los ntawm lub roj teeb, yeej ib txwm muaj kev sib haum xeeb uas yuav tsum tau ua los ntawm cov txiaj ntsig zoo ntawm lumen tso zis (tseem hu ua ci ci) thiab lub sijhawm ntev uas lub kaw lus tuaj yeem khiav ntawm lub roj teeb lub zog. . Keeb kwm, lub sijhawm ua haujlwm ntawm lub roj teeb yuav luv dua yog tias nws xav kom muaj qhov ci ntsa iab zoo dua (xav tias tib lub roj teeb tau siv). Ntawm qhov tod tes, ua tsaug rau qhov kev qhia tsis ntev los no ntawm COB LED thev naus laus zis, qhov kev lag luam tawm no tsis ua rau muaj teeb meem ntau npaum li cas. Rau peb txoj kev paub, qhov no yog thawj zaug uas COB LEDs nrog lub zog me me tau muaj peev xwm muab tau zoo heev, ultra-ci teeb. Raws li qhov tshwm sim ntawm qhov no, lub pob lithium-ion roj teeb uas nyob rau sab me thiab sib dua tuaj yeem muab lub zog rau lub teeb pom kev zoo uas yog raws li COB LEDs rau lub sijhawm ntev heev. Nyob rau hauv qhov tseeb, yog tias koj siv peb incredibly compact thiab lub teeb yuag (1.25lbs), rechargeable Mobile Power Center, peb 6W COB LED Trade Show Teeb yuav nyob twj ywm ua hauj lwm rau 14-15 teev. Tsuas yog ob peb xyoos dhau los, nws tsuas yog tsis xav tau siv lub roj teeb ntawm qhov me me los tsim cov teeb pom kev zoo rau lub sijhawm ntev. Vim li no, COB-raws li LED teeb yog tib txoj kev siv tau rau peb los xav txog thaum tsim peb lub teeb pom kev zoo heev thiab tsis tshua muaj hluav taws xob txuag hluav taws xob.
Hauv kev txiav txim siab, chip-on-board LEDs yog daim ntawv tshiab tshaj plaws thiab kev siv thev naus laus zis uas tam sim no tuaj yeem yuav. Thaum piv rau yav dhau los LED thev naus laus zis, uas yog siv rau hauv feem ntau ntawm lwm hom kev lag luam teeb pom kev lag luam niaj hnub no, COB LEDs yog, muab tso rau nws succinctly, ci dua, haus tsawg zog, thiab tsim lub teeb zoo dua. Hais kom yuav cov teeb pom kev zoo nruab nrog COB LED thev naus laus zis lub sijhawm tom ntej koj nyob hauv kev lag luam rau cov khoom lag luam.
