Umgomo Okhanyayo Wobuhlalu Belambu Le-LED enemibala emibili

I-diode ekhanyayo ivame ukubizwa ngokuthi ubuhlalu besibani be-LED, okwenziwe ngamakhemikhali afana ne- (GA), arsenic (AS), i-phosphorus (P), i-nitrogen (n). Lapho i-electron kanye ne-cavity kuhlanganiswa, ingakhipha ukukhanya okubonakalayo, ngakho-ke ingasetshenziswa ukwenza i-diode ekhipha ukukhanya. Ubuhlalu besibani se-LED ngokuvamile busetshenziswa kumasekhethi namathuluzi njengamalambu ezinkomba, noma ifomu noma isibonisi sedijithali. Umbala okhanyayo nokusebenza kahle okukhanyayo kwe-LED light-emitting diode kuhlobene nezinto nezinqubo zokwenza ama-LED. Njengamanje, ubuhlalu besibani se-LED obunemibala emithathu yokukhanya okubomvu, okuluhlaza okotshani noluhlaza okwesibhakabhaka kusetshenziswa kabanzi. Ububanzi be-wavelength bemibala ehlukene bubuye buhluke. Ngokuvamile, ukwehla kwengcindezi ye-PN kunganqunywa ukuze kunqunywe umbala wamaza wamaza ama-diode akhanyayo. 1. Isiphi isakhiwo se-encapsulation se-2-color LED light -emitting diode? Isizathu sokuthi kungani ukukhanya kwe-LED enemibala emibili kungakhipha imibala emibili yokukhanya ikakhulukazi ukupakisha imibala emibili ehlukene yama-chip kubakaki abafanayo. Kalula nje, ukwakheka kwayo kuseceleni komgogodla weshubhu le-monochrome ephumayo ejwayelekile, bese ufaka omunye umgogodla weshubhu lombala. I-LED enemibala emibili ingahlukaniswa ibe izinyawo ezimbili ngaphandle kwe-polar yobuhlalu belambu le-LED elinemibala emibili, kanye nemilenze emibili ye-co -yin -yang emibili -imibala yesibani se-LED yobuhlalu. Okwesibili, isimiso esikhanyayo se-diode ekhanyayo yethonya le-inflexible two-color LED luminous diode yizikhonkwane ezimbili. Isibonelo, kukhona izikhonkwane ezimbili ezibomvu neziluhlaza ze-LED ezikhanyayo ze-non-polarized diode. I-extreme ne-short foot welding, i-n pole kanye ne-long foot welding. Lapho i-current igeleza isuka ezinyaweni ezinde iye ezinyaweni ezimfishane, ubuhlalu besibani se-LED obubomvu nokuluhlaza obunombala ophindwe kabili busebenza ngokujwayelekile, futhi ukukhanya okuluhlaza kungasebenzi ngoba okwamanje kugeleza ukusuka onyaweni olufushane kuye onyaweni olude, ubuhlalu obukhanyayo obuluhlaza izibani ze-LED ezingenayo i-polar ezibomvu neziluhlaza eziphindwe kabili ezinemibala ye-LED zivamile, ukukhanya okuluhlaza kuwumsebenzi ovamile, izibani ezibomvu azisebenzi, ukuze kufezwe injongo yokulawula ukugeleza kwamanje kwemibala emibili ebomvu neluhlaza. Izintathu, ezintathu -ezinemilenze emithathu ye-co -yin -co -aode ezimbili -ezinemibala yobuhlalu belambu le-LED lobuhlalu obukhanyayo, ezintathu -ezinemilenze emibili -imibala ye-LED ukukhanya -i-emitting diode, imibala emibili ehlukene yamashubhu cores ihlanganyela isigxobo esisodwa. Izikhonkwane ezintathu zihlukile, futhi unyawo olude kunawo wonke oluphakathi nendawo luyisiphetho somphakathi. Ubuhlalu besibani se-LED obunezinyawo ezintathu kanye nombala we-LED bungahlukaniswa ngezinhlobo ezimbili: i-cathode evamile kanye ne-anode evamile ye-LED ngokusho kwe-polarity ehlukene yezikhonkwane zokugcina zomphakathi. Ngakho. Ungahlukanisa kanjani phakathi kwe-polarity enemilenze emithathu enemilenze emibili ye-LED ekhanyayo? Umehluko phakathi kwe-Yin yamaKhomanisi ne-yang ngokuyinhloko wukubona izigxobo ezinhle nezingezinhle zephinikhodi yokuphela yomphakathi ende kakhulu. Uma iphinikhodi yomphakathi inegethivu, i-Gongchen pole LED light -emitting diode. I-LED yamanje ivame ukugeleza isuka ku-electrode eqondile, bese kuthi i-electrode engeyinhle iphume. Emuva kuhlu
