"Ubushushu be-junction ye-LED" ayiqhelekanga kubantu abaninzi, kodwa nakubantu kwishishini le-LED! Ngoku makhe sichaze ngokweenkcukacha. Xa iI-LED iyasebenza, le miqathango ilandelayo inokukhuthaza ukushisa kwe-junction ukuba kunyuke kwiidigri ezahlukeneyo.
I-1, ibonakaliswe ngezenzo ezininzi ukuba ukunciphisa ukukhanya kwemveliso esona sizathu siphambili sokwanda kobushushu be-junction ye-LED. Okwangoku, ukukhula kwezinto eziphambili kunye nethekhnoloji yokwenziwa kwecandelo kunokuguqula uninzi lwamandla ombane akhokelela kumandla ombane okukhanya. Nangona kunjalo, ngenxa yesalathiso esikhulu kakhulu se-refractive yeItshiphu ye-LEDimpahla xa kuthelekiswa nendawo ejikelezileyo, uninzi lweefotoni (> 90%) ezenziwe kwi-chip azikwazi ukuphuphuma kakuhle kujongano, kwaye ukubonakaliswa okupheleleyo kwenzeka kujongano phakathi kwechip kunye nendawo, Ibuyela ngaphakathi kwichip kwaye ekugqibeleni ifunxwe. ngesixhobo se-chip okanye i-substrate ngokusebenzisa izibonakaliso ezininzi zangaphakathi, kwaye ibe bubushushu ngendlela ye-lattice vibration, ekhuthaza ukunyuka kobushushu bokudibanisa.
2, Ngenxa yokuba i-pn junction ayinakufezeka ngokugqithisileyo, ukusebenza kakuhle kwenaliti ye-elementi akuyi kufikelela kwi-100%, oko kukuthi, xa i-LED isebenza, ukongeza kwi-injected charge (umngxuma) kwindawo ye-n kwindawo ye-P, i-n. indawo iya kuphinda ifake intlawulo (electron) kwindawo ye-P. Ngokuqhelekileyo, i-injection yentlawulo yohlobo lokugqibela ayiyi kuvelisa umphumo we-optoelectric, kodwa iya kusetyenziswa ngendlela yokufudumala. Kwanendawo eluncedo yentlawulo etofiweyo ayisayi kukhanya yonke, kwaye enye ekugqibeleni iya kuba bubushushu xa idityaniswe nokungcola okanye iziphene kwindawo yokuhlangana.
3 、 Ubume be-electrode obuhlwempuzekileyo bento, izinto zomaleko wefestile okanye indawo yokuhlangana kunye neglu yesilivere eqhubayo zonke zinexabiso elithile lokuxhathisa. Ezi zixhathiso zibekwe kunye omnye komnye ukwenza uthotho lokumelana neIsiqalelo se-LED. Xa i-current ihamba nge-pn junction, iya kuphinda iqhube phakathi kwezi zixhasi, okubangelwa ukushisa kwe-Joule, okubangelwa ukunyuka kweqondo lokushisa kwe-chip okanye ukushisa kwe-junction.
Kakade ke, ngenkqubela yenzululwazi nobugcisa, esona sizathu siyintloko sokuba singakwazi ukuziqonda ezi zinto zingasentla nganye nganye kukuba asinakuziqonda nganye nganye kwixesha elizayo. Kakade ke, asinakuziqonda nganye nganye ngenkqubela yenzululwazi nobugcisa!
