Humusha Ubuchwepheshe Bokukhanyisa Kwe-LED Kusukela Kuzinga le-Chip

Namuhla, ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhanyisa kwe-LED kanye nokubaluleka okwandayo enkingeni yamandla emphakathini, imboni yokukhanyisa i-LED ingenise isikhathi sokuqhuma okuphelele, iheha izimali eziningi kanye namabhizinisi. Ngokombono wokuthuthukiswa kobuchwepheshe bokukhanyisa kwe-LED, kusukela ezicini ezintathu, enye yizinga le-chip, enye izinga lokupakisha, kanti enye yizinga lesicelo. Izinga le-chip ligxile kakhulu kubuchwepheshe be-LED; izinga lephakheji ngokuyinhloko ukuguqula ama-chips e-LED abe amalambu noma imithombo yokukhanya engasetshenziswa ukukhanyisa; Ukuthuthukiswa nokusetshenziswa, ukuthuthukiswa kanye nokwenza ngcono kobuchwepheshe bokuhlola izinga lokukhanyisa kwemvelo. Ezingeni le-chip, amandla okushayela okuthuthukiswa kobuchwepheshe be-chip ye-LED ahlale esekelwe ekuphishekeleni ukusebenza kahle kokukhanyisa okuphezulu. Ubuchwepheshe bokufaka bungobunye bobuchwepheshe obuyinhloko okwamanje obuthola ama-chips e-LED asebenza kahle kakhulu. Isafire ku-substrate material kanye ne-laser lining technique (LLO) kanye nobuchwepheshe obusha be-keyhered besakhiwo esime mpo esisekela izakhiwo ezime mpo kusazoba njalo. Busa. Kodwa-ke, esikhathini esizayo esiseduze, isakhiwo se-semiconductor yensimbi samukelwa ukuthuthukisa ukuxhumana kwe-Ohm, ukuthuthukisa ikhwalithi yekristalu, ukuthuthukisa izinga lokufuduka kwe-elekthronikhi kanye nokusebenza kahle komjovo kagesi. Ukusebenza kahle, ukusebenza kahle okuphelele kokukhanya okumhlophe kwe-LED kungafinyelela ku-52%. Ngokuthuthukiswa kwemiphumela yokukhanya kwe-LED, ngakolunye uhlangothi, i-chip iyancipha futhi incane, futhi inani lama-chips angasikwa ngosayizi othile liyanda, ngaleyo ndlela linciphisa izindleko ze-chip eyodwa. Ngakolunye uhlangothi Uma manje isiyi-3W, izothuthuka ku-5W naku-10W esikhathini esizayo. Lokhu kunganciphisa inani lama-chips futhi kunciphise izindleko zesistimu yesicelo ezindlekweni zezidingo zokukhanyisa. Ngamafuphi, indlela ehlanekezelwe, amandla kagesi aphezulu, kanye ne-silicon base nitride kusazoba isiqondiso sokuthuthukiswa kwe-semiconductor lighting chip.
