Xa i-LED isebenza, le miqathango ilandelayo inokwenza ukushisa kwe-junction kunyuke ukuya kumaqondo ahlukeneyo.

1, Kuye kwangqinwa ukuba umda wokusebenza okukhanyayo sesona sizathu siphambili sokunyuka kweisiphambuka LEDubushushu.Okwangoku, ukukhula kwezinto eziphambili kunye neenkqubo zokwenziwa kwecandelo kunokuguqula uninzi lwegalelo lamandla ombaneI-LED ibe ukukhanyaamandla emitha.Nangona kunjalo, ngenxa yokuba izixhobo ze-chip ze-LED zinee-coefficients ezinkulu ze-refractive kunemithombo yeendaba ezijikelezileyo, inxalenye enkulu yeefotoni (> 90%) ezenziwe ngaphakathi kwi-chip ayikwazi ukugqithisa ngokukhawuleza i-interface, kwaye ukubonakaliswa okupheleleyo kuveliswa phakathi kwe-chip kunye ne-interface yemidiya. ibuyela ngaphakathi kwi-chip kwaye ekugqibeleni ifunnwe yimpahla ye-chip okanye i-substrate ngokusebenzisa izibonakaliso ezininzi zangaphakathi, kwaye ibe shushu ngendlela ye-lattice vibration, ekhuthaza ubushushu bokudibanisa ukuba bunyuke.

2, Ekubeni i-PN junction ayinakufezeka ngokugqithisileyo, ukusebenza kakuhle kwenaliti ye-elementi akuyi kufikelela kwi-100%, oko kukuthi, ukongeza kwintlawulo (umngxuma) efakwe kwindawo ye-N kwindawo ye-P, indawo ye-N nayo iyakujova. intlawulo (electron) kwindawo ye-P xa i-LED isebenza.Ngokuqhelekileyo, uhlobo lokugqibela lwenaliti yentlawulo aluyi kuvelisa umphumo we-optoelectric, kodwa luya kusetyenziswa ngendlela yokufudumala.Nokuba indawo eluncedo yentlawulo etofiweyo ayikhaphuki yonke, enye ekugqibeleni iya kuba bubushushu xa idityaniswe nokungcola okanye iziphene kwindawo yesiphambuka.

3, Ulwakhiwo olubi lwe-electrode ye-element, izinto ze-window layer substrate okanye indawo yokuhlangana, kunye neglue yesilivere eqhubayo zonke zinemilinganiselo ethile yokuxhathisa.Ezi zixhathiso zibekwe ngokuchaseneyo ukuze zenze uthotho lokumelana neIsiqalelo se-LED.Xa i-current igeleza kwi-junction ye-PN, iya kuhamba kwakhona kula ma-resistors, okubangela ukushisa kwe-Joule, okuya kubangela ukunyuka kweqondo lokushisa kwe-chip okanye ukushisa kwe-junction.
