Ingabe Ubuhlalu Belambu Le-LED Lamandla Aphakeme Bubiza Ugesi?

Izici zobuchwepheshe zobuhlalu besibani se-LED ngobusuku Bangaphambi KukaNcibijane (1) Xhuma i-chip ne-aluminium alloyultra -i-heat material composite substrate (irediyo) ibe yinto eyodwa, futhi usebenzise amandla onyaka owodwa we-LELED ukuhlukaniswa kobuhlalu obukhanyayo be-D ubuchwepheshe. I-chip igxiliswe ngokuqondile ku-matrix yokukhipha ukushisa ukuze yenze ukumelana nokushisa phakathi kwe-chip ne-substrate yokukhipha ukushisa. Ngokusekelwe ohlelweni lokubusa okushisayo lwe-bionicism, imodeli yokumelana namandla yemodeli yokuqala yokumelana nokushisa kwesakhiwo yasungulwa ukuze kukhishwe ukushisa kokuqala kwe-chip yesibani se-LED, eyamiswa. (2) I-chip yesibani se-LED yasebusuku yasebusuku ibonakala ngesakhiwo sezendlalelo ezimbili zokupholisa nokuhlakazwa kokushisa okuhlanganisiwe kwe-chip yomthombo wokushisa. Njengoba izinga lokushisa lomthombo wokushisa likhuphuka, umoya ugeleza kurediyetha enezimbotshana. I-convection yomoya inikeza isiteshi sokugeleza, futhi ukushisa kukhishwa ngokuzenzakalelayo ukuze kuqinisekiswe ukuthi i-chip ivamile ebangeni lokushisa eliphephile lokusetshenziswa. I-thermal conductivity ethuthukisiwe kanye nesistimu yokushisa-kuya -kugeleza iqinisekisa umphumela omuhle kakhulu wokulahla ukushisa, okuthuthukisa ngokwengeziwe ukusebenza kahle kokukhanyisa kwe-chip. Ukubeka i-chip (45mil 45mi1) ukuze kuhlanganiswe okuhlanganisiwe (kugxiliswe endaweni encane) ukuze kutholwe umthombo wokukhanya wobuso obuphezulu onomphumela wokukhanya okuphezulu, enezici zokukhanya okuphezulu kokukhanya okuguquguqukayo, ukukhanya okuphelele okuphezulu, ukukhanya okuphansi (3) Namuhla , kusetshenziswa ubuchwepheshe obungenhla, futhi kusetshenziswa ubuchwepheshe obungenhla. Imodi ye-"Chip's Heading Integrated (Two -layer Structure)" isilungisiwe. Ngaphezu kwalokho, amandla walo nyaka we-LED yemoto yobuhlalu idinga ukuqinisa ukuchithwa kokushisa kwabalandeli bakagesi ngonyaka odlule, okunzima ukuhlangabezana nezidingo zesicelo esigxile emakethe. Imboni yezibani zemoto isebenzisa umthombo wokukhanya we-LED ukwenza ukulinganiselwa kwemoto ngonyaka odlule.
