Umzimba wesibani sokuhlobisa we-LED awukhiqizi imisebe ye-ultraviolet

Amandla we-tube eyodwa ye-LED 0.03 ~ 0.06 watts, esebenzisa i-DC drive, i-tube eyodwa yokushayela i-voltage engu-1.5 ~ 3.5 volts, i-15 ~ 18 mA yamanje, impendulo esheshayo, ingasebenza ngemvamisa ephezulu. Ngaphansi kwesimo somphumela ofanayo wokukhanyisa wezibani zokuhlobisa ze-LED, ukusetshenziswa kwamandla kuyingxenye eyizinkulungwane eziyishumi yaleyo yama-incandescent bulb, kanye nengxenye eyodwa yamashubhu e-fluorescent. Kulinganiselwa e-Japan ukuthi uma ama-LED anekhono elikhanyayo eliphindwe kabili asetshenziswa ukushintsha uhhafu wama-bulb aseJapane. Izibani ze-incandescent kanye ne-fluorescent. Okulingana namalitha ayizigidi eziyizinkulungwane eziyisi-6 kawoyela ongahluziwe kungongiwa minyaka yonke. Endabeni yamalambu e-bridge guardrail, ilambu le-fluorescent elinomphumela ofanayo lingaphezu kwama-watts angu-40, kuyilapho amandla e-LED ngayinye angama-watts angu-8 kuphela, futhi ingaba nemibala.

Izibani zokuhlobisa ze-LED zeholide zephrojekthi yokukhanyisa umhlobiso wefestivali zisebenzisa imisebe yensimu yokukhanya kwe-elekthronikhi ukuze zikhiphe ukukhanya, futhi imicu inobubi njengokushiswa kalula, ukufakwa kokushisa, kanye nokunciphisa ukukhanya. Isibani se-LED sincane ngosayizi futhi silula ngesisindo, simbozwe nge-epoxy resin, singamelana nokushaqeka komshini nokudlidliza okuphezulu kakhulu, futhi akulula ukuphuka. Isilinganiso sokuphila amahora angu-100,000. Ukuphila kwenkonzo yomkhosi we-LED yesibani sokuhlobisa umzimba kungafinyelela eminyakeni engu-5-10, okunganciphisa kakhulu izindleko zokugcinwa kwesibani futhi kugweme ubuhlungu bokushintshwa kwesibani njalo.

Umzimba weholide wokukhanya kwe-LED wokuhlobisa awukhiqizi imisebe ye-ultraviolet, ngakho-ke ngeke kube nomiyane abaningi eduze komthombo wokukhanya njengezibani zendabuko. Izibani zendabuko zikhanyiswa yi-voltage ephezulu ekhishwe yi-rectifier, futhi ayikwazi ukukhanyiswa lapho i-voltage incishisiwe. Umzimba wesibani sokuhlobisa iholide ungakhanyiswa ngaphakathi kwebanga elithile le-voltage, futhi ukukhanya kungalungiswa futhi.

Ama-chips e-LED wezibani zokuhlobisa ze-LED zamaholide azoguga nakanjani phakathi nenqubo yokukhanyisa, bese ukubola kokukhanya. Ngokuvamile, ngemva kwesikhathi sokusetshenziswa, izibani zizoba mnyama kancane kunokuqala, futhi ukubola okuphansi kokukhanya kungaqinisekisa impilo ende. Ezingeni lokushisa eliphakeme le-junction, ukubola kokukhanya kwe-LED kuzokhula kancane kancane njengoba izinga lokushisa likhuphuka. Uma izinga lokushisa langaphakathi le-LED lidlula izinga lokushisa lokuhlangana, ukubola kokukhanya kuzokwanda emgqeni oqondile.

Ukusebenza kahle okuphezulu okukhanyayo kuzonciphisa ukukhiqizwa kokushisa, futhi ukunciphisa ukukhiqizwa kokushisa kunganciphisa ukubola kokukhanya, futhi izinga lokushisa eliphakeme le-junction lizonciphisa izidingo zama-radiator. Ukukhetha ama-chips ebanga eliphezulu kuwumkhosi ongcono kakhulu wokukhanya wokuhlobisa we-LED. Kodwa-ke, izibani ezinama-American CREE chips azikwazi ukuthengwa engcebweni ethile, ngoba zibiza kakhulu, futhi igebe phakathi kwama-chips osayizi ofanayo cishe izikhathi ezingu-10-100, futhi igebe phakathi kwemikhiqizo eqediwe likhulu nakakhulu.
