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?

• Asebenza kanjani amamojula we-UV LED? Ukusebenza kwamanje kagesi kwenza ama-electron asakaze esigabeni sohlobo lwe-n se-semiconductor nezimbobo esigabeni sohlobo lwe-p. Zombili lezi zithwali zokushaja zihlangana emgwaqweni we-PN, lapho kwenzeka khona ukuhlanganiswa kabusha. Le nqubo ibizwa ngokuthi i-electroluminescence. Phakathi nesigaba sokuhlanganiswa kabusha, amandla akhishwa ngesimo sezinhlayiya zokukhanya.
• Izinhlobo zokukhanya ezikhishwe ze-UVA, i-UVB, noma i-UVC zihlotshaniswa nobude bokukhanya nezinto ezisetshenziselwa i-LED. Amandla e-Bandgap, umehluko wamandla phakathi kwebhendi yokuqhuba kanye nebhendi ye-valence ezintweni ze-semiconductor, inquma ubude be-wavelength. Ama-photon amafushane ama-wavelength, njenge-ultraviolet, akhiqizwa ngegebe elikhulu lebhendi. 

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-UV LED Chip

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.

• I-UV LED Array

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 kahle kule njongo. 

• Imodyuli ye-UV LED

Kwakhiwa iyunithi egcwele ehlanganisa i-chip ngayinye noma uhla lwe-LED ngama-optics ayo ahambisanayo, izingxenye zokuphatha ezishisayo, kanye nesekethe yomshayeli. Amamojula avame ukwakhiwa njengezinsiza zemisebenzi ethile njengokuphulukisa, inzalo, noma ukuhlola. 

• Ukupakisha nokuphathwa kokushisa

Ukupakisha okufanele kunikeza ukuzinza kwemishini futhi kusiza ukushabalalisa ukushisa. Izibonelo zifaka amaphakheji we-TO-39 kanye nemiklamo yentaba ebusweni. Ukuphathwa okuhle kokushisa kubaluleke kakhulu kulokhu ngoba ama-LED e-UV akhiqiza ukushisa okuningi, okungathinta kabi ukusebenza nesikhathi sokuphila kwedivayisi. 

• Umshayeli wesifunda

Le yidivayisi ye-elekthronikhi enikeza amandla ku-LED futhi iqinisekise ukuthi isebenza ngokungaguquguquki. Ibuye ivikele i-LED ekukhuphukeni kwamandla kanye nokwehla kwamandla kagesi. 

Ukusebenza nezici

• Amamethrikhi Wokusebenza

• I-Wall-Plug Efficiency (WPE): Ukulinganiswa kokukhishwa kwamandla e-optic uma kuqhathaniswa nokufakwa kwamandla kagesi.

• I-External Quantum Efficiency (EQE): Isilinganiso sama-electron akwazi ukuvusa ukukhishwa kwe-photon.

Amazinga ahlukene okukhipha ukukhanya kwama-UV LED angalinganiswa ngama-milliwatts (mW). Igama elithi irradiance libhekisela ekuqineni kokukhanya kwe-UV endaweni ethile futhi kulinganiswa ku-mW / cm².

• Ukuphila Nokuthembeka

Ama-LED ekhwalithi ye-UV avame ukuhlala amahora angaphezu kwezinkulungwane ezingamashumi amabili, kepha ubunzima obufana nokuphathwa okungalungile kokushisa nezinto ezisezingeni eliphansi kungathinta kabi ukuphila isikhathi eside. 

• Okusheshayo On / Off & Dimming Ikhono

Ezimweni eziningi, ama-LED e-UV anganikeza ukukhanya okusheshayo futhi, kwezinye izimo, ukukhanya okufiphele, okubenza babe nezimo ezihlukahlukene. 

Izicelo Nezimo Zokusetshenziswa

• Ukuphulukiswa kwe-UV

Ikhono lama-LED e-UV ukuqinisa ngokushesha ama-inks, ukumboza, okunamathisela, nama-resins kwenza lezi zinto zibe lula ukusebenza nazo. Amalambu e-UV anamandla kakhulu akhulisa isivinini sokukhiqiza ngenkathi esonga amandla, okwenza ukusetshenziswa kwawo ekwelapheni izinto kuvame kakhulu.

• Ukubulala amagciwane e-UV

Isibonelo, ama-UVC LED akhipha cishe ama-wavelengths angama-275 nm abalulekile ekunciphiseni amagciwane nezinye izigciwane. Lokhu kubenza babalulekile ekuhlanzeni amanzi, inzalo yomoya, nokungcoliswa komhlaba.

• Inzalo yezokwelapha

Emkhakheni wezokwelapha, ama-LED e-UV asiza ekuthuthukiseni inzalo kanye nendawo yokuvala, ukusiza ukugcina amazinga enhlanzeko.

• Izicelo zezimboni

Izinhlelo zokusebenza ezithile zezimboni, ezifana nokukhohlisa, i-forensic, nokuhlaziywa kwe-DNA, zisebenzisa ama-UV LED njengoba zibangela i-fluorescence ezintweni ezithile.

• I-Horticulture

Nge-Controlled Environment Agriculture, ama-LED e-UV asetshenziselwa ukukhuthaza izitshalo ukuthi zikhule futhi zithuthukise impilo yazo nokuzivikela ezifweni nezinambuzane.
