Zisebenza kanjani amamojula we-UV LED? Ukuqonda ubuchwepheshe be-UV LED
Kuyini i-UV LED? Ama-diode akhipha ukukhanya kwe-Ultraviolet (ama-LED e-UV) yizibonelo zamadivayisi we-elekthronikhi asuselwa ku-semiconductor akhiqiza imisebe yokukhanya kwe-ultraviolet (UV) ngenxa yokudlulisa amandla kagesi ngawo. Ngokungafani nezibani ze-incandescent ne-fluorescent, ama-emitters e-UV LED aqinile kakhulu futhi asebenza kahle ngoba awanazo izinto ezihambayo. Core Ukusebenza & Izimiso Zesayensi Ukwethulwa kobuchwepheshe obusha kuye kwacishe kwenza ama-UV LED abe wusizo ngezinhloso eziningi ezahlukahlukene. Lokhu kufaka phakathi ukuphrinta, inzalo yezokwelapha, ukwelashwa kwamanzi, njll. Kulesi sihloko, sizobheka isayensi, ukuklama, ukusebenza, nokusetshenziswa kwamamojula we-UV LED. Ama-LED e-UV akhipha kanjani ukukhanya? Semiconductor Materials Used in UV LEDs • I-AlGaN (i-Aluminium Gallium Nitride): Ilungele ukukhipha imisebe ejulile ye-UVC (200-280 nm). Inikeza ukuzinza okuphezulu kokushisa nokusebenza kahle kwe-photon. • I-GaN (Gallium Nitride): Isetshenziselwa ukukhishwa kwe-UVA ne-UVB ngenxa yamandla ayo nokuhamba okuphezulu kwe-electron. • I-InGaN (i-Indium Gallium Nitride): Ingenziwa ngokwezifiso ukukhipha ama-wavelengths athile, ukuhlinzeka ngezifiso zezicelo ezithile. Lezi zinto zisiza onjiniyela ukwandisa ama-UV LED ekusetshenzisweni okuhlukahlukene kwezimboni nezesayensi. Izingxenye kanye nokwakhiwa kwamamojula we-UV LED I-chip iyingxenye eyisisekelo ekhiqiza ukukhanya kwe-UV. Ukufakwa kwayo kwenziwa ngesafire noma i-AlN, esebenza njenge-substrate. Ukuze uthuthukise ukuvikelwa nokukhishwa kokukhanya, i-encapsulation ivame ukusetshenziswa. Le divayisi yakhiwe ngama-chips we-ultraviolet LED afakwe ngobuchule ukukhulisa amazinga e-irradiance. Kwezinye izinhlelo zokusebenza, ukuqina okuphezulu nokuchayeka okufanayo ekukhanyeni kwe-ultraviolet ebusweni bayo kubalulekile, futhi ama-arrays afaneleka ...
