"LED ihuza ubushyuhe" ntabwo imenyerewe kubantu benshi, ariko no kubantu bo mu nganda za LED! Noneho reka dusobanure birambuye. IyoLED ikora, ibintu bikurikira birashobora kuzamura ubushyuhe bwihuza kuzamuka muburyo butandukanye.

1 、 Byagaragaye mubikorwa byinshi ko kugabanya ingufu ziva mumucyo arimpamvu nyamukuru yo kwiyongera kwubushyuhe bwa LED. Kugeza ubu, iterambere ryibikoresho byiterambere hamwe nubuhanga bwo gukora ibice birashobora guhindura ingufu nyinshi zamashanyarazi zinjiza ziyobowe ningufu zumuriro. Ariko, bitewe nubunini bunini cyane bwo kwangaLED chipibikoresho ugereranije nuburyo bukikije, fotone nyinshi (> 90%) zakozwe muri chip ntishobora kurenga neza intera, kandi kugaragariza kwose kugaragara kumurongo uri hagati ya chip na medium, Irasubira imbere imbere ya chip hanyuma amaherezo ikinjira nibikoresho bya chip cyangwa substrate binyuze mubitekerezo byinshi byimbere, hanyuma bigahinduka ubushyuhe muburyo bwo kunyeganyega kwa lattice, biteza imbere kuzamuka kwubushyuhe.

2 、 Kuberako ihuriro rya pn ridashobora kuba ryiza cyane, imikorere yo gutera inshinge ntizigera 100%, ni ukuvuga, iyo LED ikora, usibye gutera inshinge (umwobo) mukarere ka n mukarere ka P, n agace nako kazashyiramo amafaranga (electron) mukarere ka P. Mubisanzwe, inshinge zishyirwaho mubwoko bwa nyuma ntabwo zizatanga ingaruka za optoelectric, ariko zizakoreshwa muburyo bwo gushyushya. Ndetse igice cyingirakamaro cyamafaranga yatewe ntabwo kizaba cyoroshye, kandi bimwe bizahinduka ubushyuhe iyo bihujwe numwanda cyangwa inenge mukarere gahurira.

3 structure Imiterere mibi ya electrode yibintu, ibikoresho byidirishya rya idirishya substrate cyangwa agace gahurira hamwe na kole ya feza ikora byose bifite agaciro kanini. Iyi myigaragambyo yegeranye hamwe kugirango ikore urukurikirane rwo kurwanyaIkintu cya LED. Mugihe ikigezweho kinyuze mumasangano ya pn, nayo izanyura muri résistoriste, bivamo ubushyuhe bwa Joule, bivamo kwiyongera k'ubushyuhe bwa chip cyangwa ubushyuhe bwihuriro.

Nibyo, hamwe niterambere ryubumenyi nubuhanga, impamvu nyamukuru ituma tudashobora kumva ibintu byavuzwe haruguru umwe umwe nuko tudashobora kubyumva umwe umwe mugihe kizaza. Nibyo, ntidushobora kubyumva umwe umwe hamwe niterambere rya siyanse n'ikoranabuhanga!
