NgobaAma-chips akhipha ukukhanya kwe-LED, kusetshenziswa ubuchwepheshe obufanayo, amandla e-LED eyodwa ayanda, kunciphisa ukusebenza kahle kokukhanya.Nokho, kunganciphisa inani lezibani ezisetshenziswayo, okuzuzisa ukonga izindleko;Uma amandla e-LED eyodwa emancane, ayanda ukusebenza kahle kokukhanya.Kodwa-ke, njengoba inani lama-LED adingekayo esibani ngasinye landa, ubukhulu bomzimba wesibani buyanda, futhi ubunzima bokuklama kwe-lens optical buyanda, okungaba nemiphumela emibi kwijika lokusabalalisa ukukhanya.Ngokusekelwe kuzinto ezibanzi, i-LED eyodwa enamandla asebenzayo alinganiselwe angu-350mA kanye namandla angu-1W ngokuvamile asetshenziswa.

Ngesikhathi esifanayo, ubuchwepheshe bokupakisha bubuye bube yipharamitha ebalulekile ethinta ukukhanya kwe-chips ye-LED, futhi imingcele yokumelana nokushisa kwemithombo yokukhanya ye-LED ibonisa ngokuqondile izinga lobuchwepheshe bokupakisha.Ubuchwepheshe bokukhipha ukushisa bungcono, kwehlisa ukumelana nokushisa, kuncipha ukukhanya kokukhanya, ukukhanya kwesibani kukhuphuke, futhi kuba yinde isikhathi sokuphila.

Ngokwezimpumelelo zamanje zobuchwepheshe, akunakwenzeka ukuthi i-chip eyodwa ye-LED ifinyelele ukugeleza okukhanyayo okudingekayo kwezinkulungwane noma ngisho namashumi ezinkulungwane zamalumens emithonjeni yokukhanya ye-LED.Ukuze kuhlangatshezwane nesidingo sokukhanya okugcwele kokukhanya, imithombo yokukhanya ye-chip ye-LED eminingi ihlanganiswe isibani esisodwa ukuze kuhlangatshezwane nezidingo zokukhanya okuphezulu.Ngokukhulisa ama-chips amaningi, ngconoUkusebenza kahle kokukhanya kwe-LED, ukwamukela ukupakishwa okuphezulu kokukhanya, nokuguqulwa okuphezulu kwamanje, umgomo wokukhanya okuphezulu ungafinyelelwa.

Kunezindlela ezimbili zokupholisa eziyinhloko zama-chips e-LED, okuyi-thermal conduction kanye ne-thermal convection.Isakhiwo sokuqeda ukushisa seUkukhanyisa kwe-LEDizakhiwo zihlanganisa usinki wokushisa oyisisekelo kanye nosinki wokushisa.Ipuleti lokucwiliswa emanzini lingafinyelela ukudluliswa kokushisa kwe-ultra-high heat flux density futhi ixazulule inkinga yokulahla ukushisa kwama-LED anamandla amakhulu.Ipuleti lokucwilisa liyigumbi le-vacuum elinesakhiwo esincane odongeni lwayo lwangaphakathi.Lapho ukushisa kudluliselwa emthonjeni wokushisa kuya endaweni yokuhwamuka, indawo yokusebenza ngaphakathi kwegumbi ithola i-gasification yesigaba se-liquid endaweni ye-vacuum ephansi.Ngalesi sikhathi, i-medium ibamba ukushisa futhi ikhule ngokushesha ngevolumu, futhi i-gas-phase medium igcwalisa ngokushesha igumbi lonke.Lapho i-gas-phase medium ihlangana nendawo ebandayo, ukufingqa kwenzeka, kukhulula ukushisa okuqoqwe ngesikhathi sokuhwamuka.I-liquid phase medium izobuya isuka ku-microstructure iye emthonjeni wokushisa wokuhwamuka.

Izindlela ezivame ukusetshenziswa zamandla aphezulu zama-chips e-LED yilezi: ukukala kwe-chip, ukuthuthukisa ukusebenza kahle okukhanyayo, ukusebenzisa ukupakishwa kokukhanya okuphezulu, nokuguqulwa okuphezulu kwamanje.Nakuba inani lamanje elikhishwa yile ndlela lizokhula ngokulinganayo, inani lokushisa elikhiqizwayo nalo lizokhula ngokufanele.Ukushintshela ku-thermal conductivity ephezulu ye-ceramic noma isakhiwo sokupakisha se-resin yensimbi kungaxazulula inkinga yokulahla ukushisa futhi kuthuthukise izici zangempela zikagesi, ezibonakalayo, kanye ne-thermal.Ukwandisa amandla okukhanyisa kwe-LED, ukusebenza kwamanje kwe-chip ye-LED kungandiswa.Indlela eqondile yokwandisa ukusebenza kwamanje ukukhulisa usayizi we-chip ye-LED.Kodwa-ke, ngenxa yokwanda kokusebenza kwamanje, ukuchithwa kokushisa sekuyinkinga ebalulekile, futhi ukuthuthukiswa kokupakishwa kwama-chips e-LED kungaxazulula inkinga yokukhipha ukushisa.
