2.Imfuneko yokutshatyalaliswa kobushushu
Idatha efanelekileyo ibonisa ukuba xa iqondo lokushisa lidlula ixabiso elithile, izinga lokungaphumeleli kwesixhobo liya kunyuka ngokukhawuleza, kwaye yonke i-2 ° C yokwanda kweqondo lokushisa kuya kunciphisa ukuthembeka nge-10%. Ukuze kuqinisekiswe ubomi besixhobo, ubushushu be-pn junction bufuneka ngokuqhelekileyo ukuba bube ngaphantsi kwe-110 ° C. Njengoko ukushisa kwe-pn junction kuphakama, ukukhanya okukhupha ukukhanya kwesixhobo esimhlophe se-LED kuya kutshintsha kubomvu. Kwi-100 ° C. Ubude be-wavelength bunokutshintshwa ukusuka kwi-4 ukuya kwi-9 nm ebomvu, okubangela ukuba izinga lokufunxa i-phosphor liyancipha, ukukhanya okukhanyayo kuya kuncipha, kwaye ukukhanya okumhlophe kwe-chromaticity kuya kuba kubi. Ngokumalunga nobushushu begumbi, ukukhanya okukhanyayo kwe-LED kuya kuncipha malunga ne-1% kwilitha yobushushu. Xa ii-LED ezininzi zicwangciswe ngoxinaniso ukuze zenze inkqubo yokukhanyisa ukukhanya okumhlophe, ingxaki yokutshatyalaliswa kobushushu ibaluleke kakhulu, ngoko ke ukusombulula ingxaki yokutshatyalaliswa kobushushu kuye kwaba yinto efunekayo kwizicelo zamandla e-LED. Ukuba ubushushu obuveliswa ngumbane abukwazi ukuchithwa ngexesha kwaye ukushisa kwe-junction ye-pn junction igcinwe ngaphakathi koluhlu oluvumelekileyo, aluyi kukwazi ukufumana ukukhanya okuzinzile kunye nokugcina ubomi bentambo yesibane esiqhelekileyo.
Iimfuno zokupakisha ze-LED: Ukuze kulungiswe ingxaki yokutshatyalaliswa kobushushu be-LED ephezulu yamandla, abaqulunqi kunye nabavelisi bezixhobo zasekhaya kunye nabangaphandle baye baphucula inkqubo ye-thermal yesixhobo ngokubhekiselele kwisakhiwo kunye nezixhobo.
(1) Ukwakhiwa kwepakethi. Ukuze ucombulule ingxaki yokutshatyalaliswa kobushushu bokupakishwa kwe-LED yamandla aphezulu, izakhiwo ezahlukahlukeneyo ziye zaphuhliswa kumazwe ngamazwe, ngokukodwa kubandakanywa isakhiwo se-silicon-based flip-chip (FCLED), isakhiwo sebhodi yesekethe yensimbi, kunye nesakhiwo se-micro-pump; Emva kokuba isakhiwo sephakheji sinqunywe, ukuchasana kwe-thermal kwenkqubo kuyancipha ngakumbi ngokukhetha izinto ezahlukeneyo zokuphucula ukuhanjiswa kwe-thermal yenkqubo.
