2.Ibikenewe byo gukwirakwiza ubushyuhe
Amakuru afatika yerekana ko iyo ubushyuhe burenze agaciro runaka, igipimo cyo kunanirwa cyigikoresho kizamuka cyane, kandi buri 2 ° C kwiyongera kwubushyuhe bwibice bizagabanya kwizerwa 10%. Kugirango umenye neza ubuzima bwigikoresho, ubushyuhe bwa pn busabwa muri rusange kuba munsi ya 110 ° C. Mugihe ubushyuhe bwihuriro rya pn buzamutse, uburebure bwumucyo utanga urumuri rwibikoresho bya LED byera bizahinduka umutuku. Kuri 100 ° C. Uburebure bwumuraba bushobora kuva kuri 4 kugeza kuri 9 nm itukura, ibyo bigatuma igipimo cyo kwinjiza fosifore kigabanuka, ubukana bwa luminous yose buzagabanuka, kandi urumuri rwera rwera ruzaba rubi. Hafi yubushyuhe bwicyumba, ubukana bwa LED buzagabanukaho hafi 1% kuri litiro yubushyuhe. Iyo LED nyinshi zitunganijwe mubucucike kugirango habeho sisitemu yumucyo wera, ikibazo cyo gukwirakwiza ubushyuhe kirakomeye, bityo gukemura ikibazo cyo gukwirakwiza ubushyuhe byabaye ibisabwa kugirango amashanyarazi LED akoreshwe. Niba ubushyuhe butangwa nubu ntibushobora gukwirakwira mugihe kandi ubushyuhe bwihuza bwi pn bugumaho muburyo bwemewe, ntibushobora kubona urumuri ruhamye kandi rukomeza ubuzima bwamatara asanzwe.
Ibisabwa byo gupakira LED: Kugirango dukemure ikibazo cyo gukwirakwiza ubushyuhe bwamashanyarazi menshi ya LED, abashushanya nabakora ibikoresho byo murugo no mumahanga bahinduye sisitemu yubushyuhe bwibikoresho mubijyanye nimiterere nibikoresho.
(1) Imiterere yububiko. Mu rwego rwo gukemura ikibazo cyo gukwirakwiza ubushyuhe bwo gupakira ingufu nyinshi za LED, ibikoresho bitandukanye byatejwe imbere ku rwego mpuzamahanga, cyane cyane harimo imiterere ya silikoni ishingiye kuri flip-chip (FCLED), imiterere ishingiye ku cyuma cy’umuzunguruko, hamwe n’imiterere ya pompe; Nyuma yimiterere ya pake igenwe, kurwanya ubushyuhe bwa sisitemu biragabanuka muguhitamo ibikoresho bitandukanye kugirango tunoze ubushyuhe bwumuriro wa sisitemu.
