Ingxaki yoKuchithwa koBubushushu bokuKhanya okuPhakamileyo kweeBead zezibane ze-LED

Ngokuqiniswa kokunqongophala kwamandla ehlabathi kunye nemiba yokwenziwa emini, ukukhanya kwe-LED kunye nokugcinwa kwamandla kunye nokukhuselwa kwendalo kunye nokuthembeka okuphezulu kuya kuxabiswa. Ngokuqhelekileyo, izibane ze-LED ezenziwe yimithombo yokukhanya ye-LED zenziwe nge-LED, isakhiwo sokutshatyalaliswa kobushushu, umqhubi kunye ne-lens. Okwangoku, ukutshatyalaliswa kobushushu bokukhanya okuphezulu kwezibane ze-LED kwiimarike zihlala zisebenzisa ukutshatyalaliswa kobushushu bendalo kunye nemiphumo enganelisiyo. Isiphumo asifanelekanga. Ukusa kumlinganiselo othile, ikwachaphazela ubomi besibane. Unyango lobushushu yeyona ngxaki iphambili ekusetyenzisweni kokukhanya okuphezulu kokukhanya kwesibane se-LED. Ngenxa yokuba i-P-shaped doped ye-III yesizwe se-nitrogen ilinganiselwe yi-degree yokunyibilika kwe-MG kunye namandla okuqalisa aphezulu kwindawo ye-acupuncture, ubushushu bulula kakhulu ukuvelisa kwindawo ye-P. Indlela yokutshatyalaliswa kobushushu yezixhobo zesibane se-LED ngokuyinhloko yi-conductivity ye-thermal kunye nokuhamba kobushushu; isantya sesikhokelo sobushushu sezinto eziphantsi kakhulu ze-SAPPHIRE substrate material ziya kwandisa ukuxhathisa ukushisa kwesixhobo, ukuvelisa umphumo onzima wokuzifudumeza. Impembelelo yeekhalori ekukhanyeni okuphezulu kwe-LED inkulu kakhulu. Iikhalori zigxininiswe kwiitshiphusi ezincinci. Ubushushu be-chip bukhuphuka, bubangela ukusabalalisa okungafaniyo koxinzelelo lwe-thermal, ukukhanya kokukhanya kwe-chip, kunye nokusebenza kakuhle kwe-fluorescent powder sprint; Xa ixabiso elithile, ukuphazamiseka kwesixhobo kwandiswa yimigaqo yesalathisi. Izibalo zibonisa ukuba ukushisa kwecandelo kuphakama kwi-2 C, kwaye ukuthembeka kuncipha nge-10%. Xa izicwangciso ezininzi ze-LED-dense zenza inkqubo yokukhanyisa ukukhanya okumhlophe, ingxaki yokuchithwa kweekhalori inzima kakhulu. Ukusombulula ingxaki yolawulo lobushushu kuye kwaba yinto efunekayo ekukhanyeni okuphezulu kwezixhobo zesibane se-LED. Ubudlelwane phakathi kobukhulu kunye nokutshatyalaliswa kobushushu be-chip abunakuhoywa. Eyona ndlela ichanekileyo yokwandisa ukukhanya kwamandla e-LED kukunyusa amandla okufaka. Ukuze kuthintelwe ukugcwala koluhlu lomthombo, ubukhulu beqhina le-P-N kufuneka banyuswe ngokufanelekileyo; ukwanda kwamandla egalelo kufuneka lenze iqhina. Khulisa ubushushu, emva koko unciphise ukusebenza kakuhle kwe-quantum. Ukuphuculwa kwamandla ombhobho omnye kuxhomekeke kwisakhono sesixhobo sokukhokela ubushushu obuvela kwi-P-N ukugcina izinto ezikhoyo ze-chip, isakhiwo, inkqubo yokupakisha, ubuninzi obukhoyo bangoku, kunye neemeko ezifanayo zokutshatyalaliswa kobushushu. Iqondo lobushushu liya kuqhubeka nokunyuka. Ingxaki yokutshatyalaliswa kobushushu beentsimbi zesibane se-LED ihambelana ngokusondeleyo nezinto ezininzi. Ukuze kwandiswe ubomi benkonzo yamaso wesibane se-LED kunye nokwandisa ukuthembeka, ingqwalasela ebanzi iyafuneka. Ngaphantsi kwesiseko sokuqinisekisa ukukhanya kunye nemiphumo yokukhanyisa.
