Dab tsi yog Chip-on-Board ("COB") LEDs?
Chip-on-Board los yog" COB" yog hais txog kev txhim kho ntawm ib qho liab qab LED nti nyob rau hauv kev sib cuag ncaj qha nrog lub substrate (xws li silicon carbide los yog sapphire) los tsim LED arrays. COB LEDs muaj ntau qhov zoo dua li qub LED thev naus laus zis, xws li Surface Mounted Device (" SMD") LEDs lossis Dual In-line Pob (" DIP") LEDs. Qhov tshwj xeeb tshaj plaws, COB thev naus laus zis tso cai rau ntau qhov ntim ntau dua ntawm LED array, lossis dab tsi lub teeb engineers xa mus rau kev txhim kho" lumen ntom". Piv txwv li, siv COB LED thev naus laus zis ntawm 10mm x 10mm square array ua rau 38 npaug ntau dua LEDs piv rau DIP LED thev naus laus zis thiab 8.5 npaug ntau dua LEDs piv rau SMD LED thev naus laus zis (saib daim duab hauv qab). Qhov no ua rau muaj kev siv ntau dua thiab ntau dua uniformity ntawm lub teeb. Xwb, siv COB LED thev naus laus zis tuaj yeem txo qis hneev taw thiab siv zog ntawm LED array thaum ua kom lub teeb tso zis tas li. Piv txwv li, 500 lumen COB LED array tuaj yeem ua ntau zaus me dua thiab siv zog tsawg dua li 500 lumen SMD lossis DIP LED Array.
Lwm qhov txiaj ntsig zoo ntawm kev siv COB LED thev naus laus zis yog qhov tseeb tias COB cov khoom siv tsuas muaj 1 lub voj voog thiab 2 tus neeg sib cuag rau tag nrho cov nti tsis hais tus naj npawb ntawm diodes. Qhov kev tsim hluav taws xob ib leeg no, tsis hais tus naj npawb ntawm diodes ntawm lub nti, ua rau kev yooj yim rau tag nrho cov khoom siv LED.
Qhov zoo ntawm Chip-on-Board LED arrays suav nrog:
Compactness vim qhov me me ntawm nti
High-Intensity, tshwj xeeb tshaj yog nyob ze
High-Uiformity, txawm nyob ze ua hauj lwm deb
Tsim Simplicity vim tias tsuas yog 1 Circuit Court thiab 2 tus neeg yuav tsum tau
Superior Thermal Performance rau nce lub neej, stability thiab kev ntseeg tau
Vim li cas COB LEDs tseem ceeb heev thaum khiav ntawm roj teeb lub zog?
Thaum tsim lub roj teeb-powered teeb pom kev zoo, yeej ib txwm muaj kev lag luam tawm ntawm cov txiaj ntsig zoo ntawm lumen tso zis (piv txwv li qhov ci ci) thiab qhov ntev ntawm lub sijhawm ua haujlwm ntawm lub roj teeb. Keeb kwm, qhov zoo tshaj plaws brightness xav tau, lub sij hawm luv dua (piv txwv tias koj siv tib lub roj teeb loj). Txawm li cas los xij, nrog kev txhim kho tsis ntev los no ntawm COB LED thev naus laus zis, qhov kev sib pauv no tau dhau los ua qhov teeb meem tsawg dua. Thawj zaug, tsis tshua muaj wattage COB LEDs tuaj yeem tso tawm tau zoo heev, ultra-ci teeb. Yog li ntawd, ib qho me me thiab lub teeb yuag lithium-ion roj teeb pob tuaj yeem siv lub zog COB LED raws li lub teeb rau lub sijhawm ntev. Qhov tseeb, peb 6W COB LEDTeeb pom kev lag luamyuav khiav 14-15 teev siv peb qhov me me thiab lub teeb yuag (1.25lbs) rechargeableMobile Power Center. Lub teeb pom kev zoo tshaj qhov ntev ntawm lub sijhawm siv lub roj teeb me me tsuas yog ua tsis tau tsuas yog ob peb xyoos dhau los! Qhov no yog vim li cas COB raws li LED teeb yog tib qho kev xaiv tiag tiag uas peb muaj thaum tsim peb lub teeb ci ntsa iab, ultra-npaumteeb systems. Yog li ntawd, Silicon Lightworks tsuas yog siv COBLED thev naus laus zis hauv nws cov kab kev lag luam tag nrho nthuav tawm teeb pom kev zoo.
Hauv cov ntsiab lus, chip-on-board LEDs yog cov thev naus laus zis tshiab tshaj plaws hauv kev ua lag luam niaj hnub no. Cias muab, COB LEDs ci dua, siv lub zog tsawg dua, thiab tso tawm cov teeb pom kev zoo dua piv raulaus LED technologiespom nyob rau hauv feem ntau lwm yam lag luam qhia teeb pom kev zoo hnub no. Lwm zaus koj nyob hauv kev ua lag luam rau cov teeb pom kev zoo, hais rau COB LED thev naus laus zis!
