Yiziphi Izimpawu Ezine Zobuhlalu besibani se-LED kanye nobuhlalu besibani se-LED?

Buyini ubuchwepheshe nezici zama-diode akhanyayo? Ubuchwepheshe nezici zama-diode akhanyayo: I-diode ekhanyayo ibhekisela ekukhiqizweni kobuchwepheshe be-LED (Light-Emitting Diode, Light Tube) njengento eyinhloko. Ama-diode ezinwele ayingxenye eqinile ye-semi-superconductor. I-coaxing DC yayo ibushelelezi endaweni yokubopha i-semi-superconductor ye-P-N, bese kuthi ama-electronics ebhendi kanye ne-electron yebhande le-electron kanye ne-carnitar yebhendi ye-carnitar ixhunywe komunye nomunye. , Ukuze kukhiqizwe ama-photon emitters, i-diode ecwebezelayo yezinhlobonhlobo eziphambene ingahoxisa ukukhanya kusukela kulayini wangaphakathi obomvu kuya ekukhanyeni okuluhlaza okwesibhakabhaka, kusukela kokunsomi -ukukhanya kuya kulayini onsomi. & nbsp Gundam LED ubuhlalu isibani; i-bulb ene-diode ekhanyayo incane futhi ilula, futhi ihlanganiswe ne-epoxy resin. Kungathatha amandla aphezulu ukushajwa kwemishini kanye nokushaqeka. Amahora angu-50,000-100,000, angcono kakhulu kunamahora angu-1,000 ama-tungsten filament bulbs endabuko kanye namahora angu-10,000 weshubhu lelambu le-fluorescent. Ngenxa yokuthi ukusetshenziswa kwe-diode kungafinyelela eminyakeni engu-5-10, hhayi kuphela inzuzo yokuguqulwa kwesibani ingandiswa, kodwa futhi izici ezingaqhutshwa amandla aphezulu -DC angashayela ukukhanya. Amandla ayingxenye eyodwa kuphela yeshubhu lelambu le-fluorescent, ngakho-ke i-diode yokukhanya iphinde yaxhumanisa amandla okonga amandla nokonga amandla. Uma kuqhathaniswa neminye imithombo yokukhanya yendawo yonke ekuqaleni, amabhamuza okukhanya ama-tungsten acishe abe ngu-15 LM/W, ukukhanya kwelanga okuyi-fluorescent cishe ku-45 60 LM/W, amalambu a-HID acishe abe ngu-120 150 LM/W. Kancane kancane iye yazuza kubi; lokhu ukuqhathaniswa kwezakhiwo zokukhanyisa ze-diode yokukhanya nezinye izibani ezivamile: izici zesimo sokukhanyisa i-diode yokukhanyisa ukukhanya kwe-diode ekhanyayo, umthombo wokushisa wama-diode, izimo zokusebenza ezibanzi, usayizi ophakathi, oshaqisayo, ogxilile. ukukhanya kwelanga (i-fluorescence fluorescence Light) Ukukhanyisa amandla okulondoloza ukukhanya kwe-fluorescent, kodwa ukuqedwa kwezinkinga ezifana nokuhlanzwa kwe-mercury ne-mercury, amabhamuza amhlophe we-thermal tungsten filament awasebenzi kahle, ukusetshenziswa kwamandla okuphezulu, ukuphila okufushane, nezinwele ezintekenteke nama-diode akhanyayo. Kodwa-ke, abantu abasebenzisa kancane i-diode bazothola ukuthi i-diode ekhanyayo ibushelelezi ikakhulukazi ngenxa yokushelela, okungaba kalula ukushisa kokuhlupheka okuvela ekukhanyeni, okwenza i-diode yezinwele ikhanye. Ngaleso sikhathi, i-diode ye-diode yenza ukuthi ingahlushwa ukushisa ngokushesha ngangokunokwenzeka, futhi ukuphila kwayo kuzoncishiswa. Isihloko sivela kubuhlalu besibani se-LED.
