Ngenxa yokunqongophala kwamandla ehlabathi kunye nongcoliseko lokusingqongileyo, umboniso we-LED unendawo ebanzi yesicelo ngenxa yeempawu zokonga amandla kunye nokukhuselwa kwendalo. Kwintsimi yokukhanyisa, ukusetyenziswa kweIimveliso ezikhanyayo ze-LEDitsala umdla wehlabathi. Ngokuqhelekileyo, ukuzinza kunye nomgangatho wezibane ze-LED zihambelana nokutshatyalaliswa kobushushu bomzimba wesibane ngokwawo. Okwangoku, ukutshatyalaliswa kobushushu bokukhanya okuphezulu kwezibane ze-LED kwiimarike zihlala zithatha ukutshatyalaliswa kobushushu bendalo, kwaye umphumo awufanelekanga.Izibane ze-LEDezenziwe ngumthombo wokukhanya we-LED ziqulunqwe yi-LED, isakhiwo sokutshatyalaliswa kobushushu, umqhubi kunye ne-lens. Ngoko ke, ukuchithwa kobushushu kuyingxenye ebalulekileyo. Ukuba i-LED ayikwazi ukufudumala kakuhle, ubomi bayo benkonzo buya kuchaphazeleka.

Ulawulo lobushushu yeyona ngxaki iphambili kwisicelo seukukhanya okuphezulu kwe-LED

Ngenxa yokuba i-p-type doping yeqela le-nitrides yeqela le-III ilinganiselwe kukunyibilika kwabamkeli be-Mg kunye namandla okuqalisa aphezulu emingxunyeni, ubushushu bulula ngokukodwa ukuveliswa kummandla wohlobo lwe-p, kwaye obu bushushu kufuneka buchithwe kwi-sink yobushushu. kwisakhiwo sonke; Iindlela zokutshatyalaliswa kobushushu zezixhobo ze-LED zihamba phambili ngokuhambisa ubushushu kunye nokushisa ubushushu; I-thermal conductivity ephantsi kakhulu ye-sapphire substrate material ikhokelela ekwandeni kokumelana ne-thermal yesixhobo, okukhokelela kwisiphumo esibi sokuzifudumeza, esinefuthe elibi kakhulu ekusebenzeni kunye nokuthembeka kwesixhobo.

Impembelelo yobushushu ekukhanyeni okuphezulu kwe-LED

Ubushushu bugxininiswe kwi-chip encinci, kwaye ukushisa kwe-chip kuyanda, okubangela ukusabalalisa okungafaniyo koxinzelelo lwe-thermal kunye nokuncipha kwe-chip luminous ufanisi kunye nokusebenza kakuhle kwe-phosphor lasing; Xa iqondo lobushushu ligqithise ixabiso elithile, isantya sokusilela kwesixhobo sanda kakhulu. Idatha yeenkcukacha-manani ibonisa ukuba ukuthembeka kwehla nge-10% rhoqo nge-2 ℃ ukunyuka kweqondo lokushisa. Xa ii-LED ezininzi zicwangciswe ngokuxineneyo ukwenza inkqubo yokukhanyisa emhlophe, ingxaki yokutshatyalaliswa kobushushu ibaluleke kakhulu. Ukuxazulula ingxaki yokulawula ubushushu kuye kwaba yinto efunekayo yokusetyenziswa kokukhanya okuphezulu kwe-LED.

Ubudlelwane phakathi kobungakanani betshiphu kunye nokutshatyalaliswa kobushushu

Eyona ndlela ichanekileyo yokuphucula ukukhanya kwamandla e-LED ukubonisa isikrini kukwandisa amandla okufaka, kwaye ukwenzela ukuthintela ukuhluthwa komgangatho osebenzayo, ubungakanani be-pn junction kufuneka bonyuswe ngokufanelekileyo; Ukwandisa amandla egalelo ngokuqinisekileyo kuya kwandisa ubushushu be-junction kunye nokunciphisa ukusebenza kakuhle kwe-quantum. Ukuphuculwa kwamandla e-transistor enye kuxhomekeke kwisakhono sesixhobo sokuthumela ngaphandle ubushushu ukusuka kwi-pn junction. Phantsi kweemeko zokugcinwa kwezinto ezikhoyo ze-chip, ulwakhiwo, inkqubo yokupakisha, ukuxinana kwangoku kwi-chip kunye nokutshatyalaliswa kobushushu obulinganayo, ukwandisa ubungakanani be-chip kuphela kuya kwandisa ubushushu bokudibanisa.
