NgobaUkukhanya kwe-LED-ama-chips akhiphayo, kusetshenziswa ubuchwepheshe obufanayo, amandla e-LED eyodwa ayanda, anciphisa ukusebenza kahle kokukhanya, kodwa anganciphisa inani lezibani ezisetshenziswayo, okusiza ukonga izindleko; Uma amandla e-LED eyodwa eba mancane, ayanda ukusebenza kahle kokukhanya. Kodwa-ke, inani lama-LED adingekayo esibani ngasinye liyakhula, ubukhulu bomzimba wesibani buyanda, futhi ubunzima bokuklama kwe-lens optical buyanda, okuzoba nomthelela omubi emgqeni wokusabalalisa ukukhanya. Ngokusekelwe ezicini ezibanzi, i-LED enesilinganiso esisodwa sokusebenza samanje esingu-350mA namandla angu-1W ngokuvamile isetshenziswa.

Ngesikhathi esifanayo, ubuchwepheshe bokupakisha buphinde bube yipharamitha ebalulekile ethinta ukusebenza kahle kokukhanya kwama-chips e-LED. Ipharamitha yokumelana nokushisa komthombo wokukhanya we-LED ikhombisa ngokuqondile ileveli yobuchwepheshe bokupakisha. Ubuchwepheshe bokukhipha ukushisa bungcono, kwehlisa ukumelana nokushisa, kuncipha ukukhanya kokukhanya, ukukhanya kukhuphuke futhi kuphila isikhathi eside kwesibani.

Ngokuqondene nezimpumelelo zamanje zobuchwepheshe, uma ukukhanya okukhanyayo komthombo wokukhanya we-LED ufuna ukufinyelela izimfuneko zezinkulungwane noma ngisho namashumi ezinkulungwane zamalumens, i-chip eyodwa ye-LED ayikwazi ukuyifinyelela. Ukuze kuhlangatshezwane nesidingo sokukhanya kokukhanyisa, umthombo wokukhanya wama-chips amaningi e-LED uhlanganiswa ngesibani esisodwa ukuze uhlangabezane nokukhanya okuphezulu. Umgomo wokukhanya okuphezulu ungafinyelelwa ngokuthuthukisa ukusebenza kahle okukhanyayo kwe-LED, ukusebenzisa ukupakishwa okuphezulu kokukhanya okukhanyayo kanye nomthamo ophezulu ngokusebenzisa i-multi-chip enkulu.

Kunezindlela ezimbili eziyinhloko zokukhipha ukushisa kwama-chips e-LED, okuyi-heat conduction kanye ne-heat convection. Isakhiwo sokuqeda ukushisa seIzibani ze-LEDihlanganisa usinki wokushisa oyisisekelo kanye ne-radiator. Ipuleti lokucwiliswa lingakwazi ukubona ukudluliswa kokushisa kwe-ultra-high heat flux futhi lixazulule inkinga yokukhipha ukushisaI-LED enamandla amakhulu. Ipuleti lokumanzisa liyimbobo engenalutho enesakhiwo esincane odongeni lwangaphakathi. Lapho ukushisa kudluliselwa kusuka emthonjeni wokushisa kuya endaweni yokuhwamuka, indawo yokusebenza emgodini izokhiqiza isenzakalo se-gasification yesigaba soketshezi endaweni ye-vacuum ephansi. Ngalesi sikhathi, i-medium ibamba ukushisa futhi ivolumu ikhula ngokushesha, futhi i-gas phase medium izogcwalisa ngokushesha umgodi wonke. Lapho i-gas-phase medium ithinta indawo ebanda kakhulu, ukujiya kuzokwenzeka, kudedele ukushisa okunqwabelene ngesikhathi sokuhwamuka, futhi uketshezi olujiyile olujiyile luzobuyela emthonjeni wokushisa wokuhwamuka kusukela ku-microstructure.

Izindlela ezivame ukusetshenziswa zamandla aphezulu zama-chips e-LED yilezi: ukukhuliswa kwe-chip, ukuthuthukiswa kokusebenza kahle okukhanyayo, ukupakishwa ngokusebenza kahle kokukhanya okuphezulu, namandla amakhulu. Nakuba inani le-luminescence yamanje lizokhula ngokulinganayo, inani lokushisa nalo lizokhula. Ukusetshenziswa kwe-thermal conductivity ephezulu ye-ceramic noma isakhiwo sokupakisha se-resin yensimbi kungaxazulula inkinga yokukhipha ukushisa futhi kuqinise izici zangempela zikagesi, optical kanye ne-thermal. Ukuze kuthuthukiswe amandla ezibani ze-LED, ukusebenza kwamanje kwama-chips e-LED kungandiswa. Indlela eqondile yokwandisa ukusebenza kwamanje ukukhulisa usayizi wama-chips e-LED. Kodwa-ke, ngenxa yokwanda kwamandla okusebenza, ukuchithwa kokushisa sekuyinkinga ebalulekile. Ukuthuthukiswa kwendlela yokupakisha yama-chips e-LED kungaxazulula inkinga yokukhipha ukushisa.
