Waa maxay shaashadda COB LED?

Waa maxay shaashadda COB LED?

COB (Chip on Board) waa tignoolajiyada baakadaha LED-ka oo ka duwan tignoolajiyada soo-bandhigidda LED-ka ee soo jireenka ah. Tiknoolajiyada COB waxay si toos ah ugu dhejisaa jajabyo badan oo LED ah oo looxa wareegga, taas oo meesha ka saaraysa baahida baakadaha kala duwan. Tiknoolajiyadani waxay kordhisaa dhalaalka waxayna yaraynaysaa kulaylka, taasoo ka dhigaysa bandhigga mid aan kala go 'lahayn.

Faa'iidooyinka marka la barbar dhigo shaashadaha LED-dhaqameedka

Shaashadaha COB LED waxay leeyihiin faa'iidooyin muuqda marka loo eego muraayadaha LED-ka ee caadiga ah marka loo eego waxqabadka. Ma laha wax farqi ah oo u dhexeeya chips LED, hubinta iftiinka isku midka ah iyo ka fogaanshaha dhibaatooyinka sida "saameynta albaabka shaashadda". Intaa waxaa dheer, shaashadaha COB waxay bixiyaan midabyo sax ah iyo kala duwanaansho sare.

Faa'iidooyinka shaashadda COB LED

Sababtoo ah cabbirka yar ee chips LED, cufnaanta tignoolajiyada baakadaha COB ayaa si aad ah u kordhay. Marka la barbar dhigo qalabka dusha sare leh (SMD), habaynta COB waa mid is haysta, hubinta isku mid ahaanshaha soo bandhigida, ilaalinta xoojinta sare xitaa marka lagu eego meel u dhow, iyo isagoo leh waxqabad kuleyl aad u fiican, taas oo hagaajinaysa xasilloonida iyo isku halaynta. Chips-ka baakadaysan ee COB iyo biinanka waxay kor u qaadaan cidhiidhiga hawada iyo iska caabinta xoogagga dibadda, samaynta dusha sare ee aan sinnayn. Intaa waxaa dheer, COB waxay leedahay qoyaan-celin sare, anti-static, waxyeello-caddayn iyo guryaha-booska, iyo heerka ilaalinta dusha sare wuxuu gaari karaa IP65.

COB LED bandhigay shaashadda

Marka la eego habka farsamada, tignoolajiyada SMD waxay u baahan tahay alxanka dib u qulqulka. Marka heerkulka koollada alxanka uu gaaro 240°C, heerka luminta resin epoxy wuxuu gaari karaa 80%, taasoo si fudud u sababi karta in xabagta ay ka soocdo koobka LED-ka. Tignoolajiyada COB uma baahna hannaan dib-u-qulqulaya oo sidaas awgeed aad ayey u deggan tahay.

Muuqaal dhow: Saxnaanta Pitch Pixel

Tignoolajiyada COB LED waxay hagaajinaysaa heerka pixel-ka. Dhererka pixel-ka-yar macnaheedu waa cufnaanta pixel sare, sidaas darteed lagu gaaro xallin sare. Daawadeyaashu waxay arki karaan sawirro cad xitaa haddii ay u dhow yihiin kormeeraha.

Iftiiminta mugdiga: Iftiin hufan

Tiknoolajiyada COB LED waxaa lagu gartaa daadinta kulaylka hufan iyo iftiinka iftiinka hooseeya. Chip-ka COB wuxuu si toos ah ugu dhejiyaa PCB-ga, kaas oo balaadhinaya aagga kulaylka iyo iftiinka iftiinka ayaa aad uga fiican kan SMD. Diidmada kulaylka ee SMD waxay inta badan ku tiirsan tahay barkinta hoose.

Kordhinta Horizon: Aragtida

Tiknoolajiyada yar-yar ee COB waxay keentaa xaglo daawasho oo ballaadhan iyo iftiin sare, waxayna ku habboon tahay muuqaallo kala duwan oo gudaha iyo dibadda ah.

Adkeysi Adag

Tiknoolajiyada COB waa mid u adkaysata oo aan saameyn ku yeelan saliidda, qoyaanka, biyaha, boodhka iyo oksaydhka.

Isbarbardhigga Sare

Isbarbardhigga waa tilmaame muhiim ah oo muujinaya shaashadaha LED-ka. COB waxay kor u qaadaa isbarbardhigga heer cusub, oo leh saamiga isbarbardhigga taagan ee 15,000 ilaa 20,000 iyo saamiga isbarbardhigga firfircoon ee 100,000.

Xilligii Cagaaran: Waxtarka Tamarta

Marka la eego waxtarka tamarta, tignoolajiyada COB ayaa ka horeysa SMD waana arrin muhiim u ah dhimista kharashyada hawlgalka marka la isticmaalayo shaashado waaweyn muddo dheer.
