Muri iki gihe iterambere ryihuta ryiterambere rya tekinoroji, LED yerekana ibisubizo byahindutse kuburyo bugaragara. Ikoranabuhanga rya LED ryahinduye inganda zimurika, ritanga ingufu zikoresha kandi zirambye kubakoresha ndetse nubucuruzi. Mu bikoresho bitandukanye bya LED, COB (Chip on Board) yagaragaye nk'ihitamo ryiza kubera imiterere ya tekiniki. Muri iki kiganiro, tuzasuzuma impamvu zituma COB ifata inyungu kurenza ikoranabuhanga rya SMD rikoreshwa cyane (Surface Mount Device). Kuva imyuka ihumanya ikirere kugeza kunoza ibidukikije, COB irusha abanywanyi bayo.
1.SMD na COB: Niki Cyiza?
Iyo bigeze kuri LED yerekana ikoranabuhanga, abahatana babiri nyamukuru biganje ku isoko: SMD na COB. Mugihe Surface Mount Device imaze igihe kinini ijya guhitamo ibisubizo byumucyo wa LED, COB yagaragaye nkubundi buryo bukomeye.
Bitandukanye na SMD, igizwe na LED diode kugiti cye ku kibaho cyumuzunguruko, COB ikubiyemo chip nyinshi za LED muburyo bumwe. Iboneza ridasanzwe ntabwo ryongera gusa umucyo nuburemere bwurumuri ahubwo binagabanya urumuri rwerekana intera ndende. Igishushanyo mbonera cya COB gisubiza urumuri rutagira urumuri hamwe nuburinganire bwamabara menshi.
II. Ubushyuhe buke hamwe n'ubushyuhe buke
Kimwe mubyiza byibanze bya COB kurenza SMD nubushobozi bwayo bwo kuyobora ubushyuhe. Tekinoroji ya COB itanga ubushyuhe buke bitewe nubushakashatsi bwayo bworoshye. Kurwanya ubushyuhe bigena uburyo ubushyuhe butandukana na LED module, bigatuma COB ikora neza mukugabanya ubushyuhe. Ibi ntabwo bivamo kuramba gusa no kugabanya ibisabwa byo kubungabunga ariko binongera umutekano nkukoCOB modulesntibakunze gushyuha.
III. Kurinda Byiza Kurwanya Ibidukikije
Kwerekana COBitanga uburinzi buhebuje kubintu bitandukanye bidukikije, byemeza kuramba no kwizerwa mubihe bitandukanye. Yakize hamwe na epoxy resin kugirango atezimbere imikorere yo kurinda. Ifite imbaraga zo kurwanya ubushuhe, ivumbi, static, okiside, nu mucyo wubururu. Ubu burinzi bwongerewe imbaraga butuma COB itanga ibisubizo kugirango itere imbere mubidukikije bigoye nko hanze cyangwa ahantu hafite ubuhehere bwinshi. Byongeye kandi, COB irwanya okiside ituma LEDs igumana umucyo nukuri kwamabara mugihe kinini, bitandukanye na SMD bagenzi babo.
IV. Ubwiza bwijimye kandi bukarishye.
Ubwubatsi bwa tekinoroji ya COB ntabwo yongerera ubushobozi bwo gucunga ubushyuhe no kurinda gusa ahubwo binagira uruhare mu kumurika. Bitewe na chip ya LED yegeranye cyane, COB itanga urumuri rwibanze kandi rukomeye rwumucyo, bikavamo igicucu cyijimye nibisobanuro birambuye. Ibi bituma COB ibereye cyane mubisabwa aho usobanutse neza kandi itandukanye cyane ni ingoro ndangamurage, kwerekana ibicuruzwa, hamwe na galeries. Itara rikarishye ritangwa na tekinoroji ya COB ryongera imbaraga zo kugaragara no gusobanuka ahantu hakeye.
Nkuko LED Yerekana Inganda zikomeje gutera imbere,Ikoranabuhanga rya COBbyagaragaye nkuburyo bushya kandi busumba ubundi bwo kwerekana LED ibisubizo. Ibiranga tekiniki, nkibisohoka byumucyo umwe, ibyuka bihumanya ikirere, byongerewe imbaraga zo kwirinda ibidukikije, n’umucyo ukarishye, bituma uhitamo bidashoboka. COB ntabwo itanga imikorere myiza no kuramba gusa ahubwo inatanga ubuziranenge bwibonekeje, nibyingenzi mubikorwa bitandukanye.
Hamwe no kwamamara kwayo no gutera imbere mubikorwa byo gukora,Ikoranabuhanga rya COBiragenda iboneka byoroshye kubaguzi nubucuruzi kwisi yose. Kwakira Kwerekana COBibisubizo bisezeranya gutanga urumuri rwinshi, rukora neza, kandi rurerure rwo kumurika mugihe duhindura uburyo tumurikira ibidukikije.
