Inzira zo gukemura ubushyuhe bwa LED
3. 1 Gutoranya guhitamo hamwe nubushyuhe bwiza bwumuriro
Hitamo insimburangingo hamwe nubushyuhe bwiza bwumuriro, nkibikoresho bya Al-bishingiye ku cyuma cyanditseho imbaho zicapye (MCPCBs), ububumbyi, hamwe n’ibyuma bifata ibyuma, kugirango wihutishe ikwirakwizwa ry’ubushyuhe kuva kuri epitaxial kugeza kuri substrate yubushyuhe. Mugutezimbere igishushanyo mbonera cyubushyuhe bwa MCPCB, cyangwa ugahita uhuza ceramics na substrate yicyuma kugirango habeho icyuma gishingiye ku cyuma giciriritse giciriritse ceramic (LTCC2M) substrate, substrate ifite ubushyuhe bwiza bwumuriro hamwe na coefficient ntoya yo kwagura ubushyuhe irashobora kuboneka .
3.2 Kurekura ubushyuhe kuri substrate
Kugirango ukwirakwize ubushyuhe kuri substrate kubidukikije bidukikije byihuse, kurubu, ibikoresho byicyuma bifite ubushyuhe bwiza bwumuriro nka Al na Cu mubusanzwe bikoreshwa nkibikoresho byo gushyushya ubushyuhe, kandi hongeweho gukonjesha ku gahato nkabafana nu miyoboro yubushyuhe. Hatitawe kubiciro cyangwa isura, ibikoresho byo gukonjesha byo hanze ntibikwiriye kumurika LED. Kubwibyo, ukurikije itegeko ryo kubungabunga ingufu, gukoresha ceramique ya piezoelectric ceramique nkicyuma gishyushya kugirango ihindure ubushyuhe mukuzunguruka no gukoresha ingufu zubushyuhe bizahinduka kimwe mubyibandwaho mubushakashatsi buzaza.
3.3 Uburyo bwo kugabanya ubukana bwumuriro
Kubikoresho bifite ingufu nyinshi za LED, imbaraga zose zirwanya ubushyuhe nigiteranyo cyumuriro wumuriro wubushyuhe bwinshi kumuhanda wubushyuhe uva pn uhuza ibidukikije, harimo nubushyuhe bwimbere bwokwirinda ubushyuhe bwa LED ubwayo nubushyuhe bwimbere. kurohama kubuyobozi bwa PCB. Kurwanya ubushyuhe bwa kole yubushyuhe bwumuriro, kurwanya ubushyuhe bwumuriro wa koleji yubushyuhe hagati ya PCB nubushyuhe bwo hanze, hamwe nubushyuhe bwumuriro bwumuriro wo hanze, nibindi, buri cyuma gishyuha mumuzunguruko wubushyuhe bizatera bimwe inzitizi zo guhererekanya ubushyuhe. Kubwibyo, kugabanya umubare wubushyuhe bwimbere no gukoresha firime yoroheje kugirango ubyare umusaruro wingenzi wa electrode yubushyuhe hamwe nubushyuhe bwo kubika ibyuma bishobora kugabanya cyane ubushyuhe bwumuriro. Iri koranabuhanga rishobora guhinduka LED ifite ingufu nyinshi mugihe kizaza. Icyerekezo nyamukuru cyicyerekezo cyo gukwirakwiza ubushyuhe.
3.4 Isano iri hagati yumuriro wumuriro numuyoboro wo gukwirakwiza ubushyuhe
Koresha umuyoboro mugufi ushoboka wo gukwirakwiza ubushyuhe. Umwanya muremure wo gukwirakwiza ubushyuhe, niko birwanya ubushyuhe bwumuriro kandi niko bishoboka cyane ko amacupa yumuriro.
