Ngenxa yokushoda kwamandla emhlabeni wonke kanye nokungcoliswa kwemvelo, isibonisi se-LED sinendawo ebanzi yohlelo ngenxa yezimpawu zakhona zokonga amandla nokuvikelwa kwemvelo. Emkhakheni wokukhanyisa, ukusetshenziswa kweImikhiqizo ekhanyayo ye-LEDidonsa ukunaka komhlaba. Ngokuvamile, ukuzinza kanye nekhwalithi yezibani ze-LED kuhlobene nokuchithwa kokushisa komzimba wesibani ngokwawo. Njengamanje, ukuchithwa kokushisa kokukhanya okuphezulu kwezibani ze-LED emakethe ngokuvamile kwamukela ukuchithwa kokushisa kwemvelo, futhi umphumela awulungile.Izibani ze-LEDeyenziwe ngumthombo wokukhanya we-LED yakhiwe nge-LED, isakhiwo sokushisa ukushisa, umshayeli namalensi. Ngakho-ke, ukuchithwa kokushisa nakho kuyingxenye ebalulekile. Uma i-LED ingakwazi ukushisa kahle, impilo yayo yesevisi nayo izothinteka.

Ukuphathwa kokushisa kuyinkinga enkulu ekusetshenzisweni kweukukhanya okuphezulu kwe-LED

Ngenxa yokuthi i-p-type doping ye-group III nitrides inqunyelwe ukunyibilika kwama-Mg amukela amandla namandla aphezulu okuqala ezimbobo, ukushisa kulula kakhulu ukukhiqizwa endaweni yohlobo lwe-p, futhi lokhu kushisa kufanele kuhlakazwe kusinki wokushisa. ngokusebenzisa sonke isakhiwo; Izindlela zokukhipha ukushisa zamadivayisi we-LED ngokuyinhloko yi-heat conduction kanye ne-heat convection; I-thermal conductivity ephansi kakhulu ye-sapphire substrate material iholela ekwenyukeni kokumelana nokushisa kwedivayisi, okuholela kumphumela ojulile wokuzifudumeza, onomthelela omubi kakhulu ekusebenzeni nasekuthembekeni kwedivayisi.

Umthelela wokushisa ekukhanyeni okuphezulu kwe-LED

Ukushisa kugxile ku-chip encane, futhi izinga lokushisa le-chip liyakhuphuka, okuholela ekusabalaliseni okungajwayelekile kokucindezeleka okushisayo kanye nokuncipha kokusebenza kahle kwe-chip kanye nokusebenza kahle kwe-phosphor lasing; Uma izinga lokushisa lidlula inani elithile, izinga lokuhluleka kwedivayisi likhuphuka kakhulu. Idatha yezibalo ibonisa ukuthi ukwethembeka kwehla ngo-10% njalo ngo-2 ℃ ekukhuphukeni kwezinga lokushisa lengxenye. Uma ama-LED amaningi ehlelwa ngokuminyene ukuze akhe uhlelo lokukhanyisa olumhlophe, inkinga yokukhishwa kokushisa inkulu kakhulu. Ukuxazulula inkinga yokuphathwa kokushisa sekuyinto edingekayo ukuze kusetshenziswe ukukhanya okuphezulu kwe-LED.

Ubudlelwano phakathi kosayizi we-chip kanye nokuchithwa kokushisa

Indlela eqondile kakhulu yokuthuthukisa ukukhanya kwamandla esikrini sokubonisa se-LED ukukhulisa amandla okufaka, futhi ukuze kuvinjwe ukugcwaliswa kwesingqimba esisebenzayo, usayizi we-pn junction kufanele ukhuliswe ngokufanele; Ukwandisa amandla okufaka kuzokwandisa ngokungenakugwenywa izinga lokushisa lokuhlangana futhi kunciphise ukusebenza kahle kwe-quantum. Ukuthuthukiswa kwamandla we-transistor eyodwa kuncike ekhonweni ledivayisi lokuthekelisa ukushisa kusuka ku-pn junction. Ngaphansi kwezimo zokugcina izinto ezikhona ze-chip, ukwakheka, inqubo yokupakisha, ukuminyana kwamanje ku-chip kanye nokushabalaliswa kokushisa okufanayo, ukwandisa usayizi we-chip kukodwa kuzokwandisa izinga lokushisa lokuhlangana.
