Yiziphi Izinto Ezisetshenziswa Ku-UV Led Chip

Njengoba sonke sazi, ama-ultraviolet light-emitting diode angama-semiconductors akhipha ukukhanya ngobude obuthile begagasi lapho ukukhanya kudlula kuwo. Ama-LED aziwa njengamadivayisi esimo esiqinile. Izinkampani eziningi zakha ama-chips e-UV asekelwe ku-UV ngezinqubo zezimboni, amathuluzi ezokwelapha , ukuvala inzalo nokubulala amagciwane, amathuluzi okuqinisekisa amadokhumenti, nokuningi. Kungenxa ye-substrate yabo kanye nezinto ezisebenzayo. Yenza ama-LED akhanye, atholakale ngezindleko eziphansi, alungise i-voltage, futhi anciphise amandla okukhipha ukukhanya ukuze asetshenziswe ngokugcwele.

Lo mhlahlandlela obanzi uzokuhambisa ezintweni ezisetshenzisiwe, uqhathanise izinzuzo, futhi uchaze ukuthi ungakhetha kanjani i-chip ye-LED efanele.

Izinto Ezibalulekile Ezisetshenziswa Kuma-LED e-UV

Izinto ezibalulekile ezisetshenziselwa ukukhiqiza i-ultraviolet LED chip zihlukaniswe ngama-substrates nezinto ezisebenzayo. Izinto ezintathu ezilandelayo ezibalulekile zisetshenziswa ngokugqamile ukwenza ama-chips.

1  I-Aluminium Nitride

Lokhu okubalulekile kusebenzisa i-UWBG noma i-Ultra-Wide Bandgap Technology. Le nto ejulile ikhipha ukukhanya ebangeni le-ultraviolet, futhi izinto ezifana ne-gallium nitride ne-silicon carbide zisetshenziswa eceleni kwayo ukuze kukhuliswe ukusebenza kahle kwamandla.

Le nto isebenza kubude obungaphansi kuka-315nm. Ama-chips e-Aluminium Nitride asiza ngokusebenza okuphezulu okushisayo kanye nokuthuthukisa ukuphuma kukagesi kumadivayisi e-LED. I-AIN noma i-aluminium nitride ingena esikhundleni se-BeO noma i-beryllium oxide ngoba ayinazo izingozi zempilo. Ingamelana namazinga okushisa aphezulu futhi ayinamthungo ezinhlelweni zikagesi namanye amadivaysi.

2  I-AlGaN Alloys

Le ngxubevange iyinhlanganisela ye-Aluminium, i-Gallium, ne-Nitrogen, enikeza ubude begagasi obufika ku-400nm. Le alloy esetshenziselwa ama-chips e-UV LED isebenzisa kakhulu Imojula ye-UV-A  Le nto yengxubevange ihlangene inobude obubanzi be-spectral obukhipha ukukhanya kwe-ultraviolet, okuyenza ifaneleke imishini yezokwelapha, izinzwa, umoya nomoya. Amagciwane amanzi , ukuvala inzalo, njll. Kuyasiza futhi ekwenzeni ngcono ukusebenza kwamadivayisi.

Ngenxa yezakhiwo ze-physico-chemical of AIGaN, inqubekelaphambili ebalulekile isifinyelelwe ekuthuthukiseni ukukhiqizwa kwama-chip. Kuyimpahla yekhwalithi ephezulu ethuthukisa ukusebenza kahle kwamadivayisi we-UV LED. Zisetshenziselwa ngisho nokukhiqiza ama-chips eco-friendly, ahlakaniphile, futhi aqhubekayo.

3  I-substrate

Lesi sici esiyinhloko ama-chips’ isisekelo, amandla, kanye nokwesekwa. I-substrate ebaluleke kakhulu esetshenziselwa ama-UV LEDs iSapphire. Isobala, inokutholakala okubanzi, futhi itholakala ngezindleko eziphansi. Ngaphandle kwalezi zici, iSapphire substrate inezinye izinzuzo eziningi, njengekhwalithi ephezulu, impahla evuthiwe ekhona, amandla ayo okumelana namazinga okushisa aphakeme, ukuhlanzeka kalula, namandla aqinile emishini.

Ngaphezu kwalokho, iSapphire substrate kuma-chips ihlangabezana nezidingo ezikhulayo zemakethe yokwelapha. Izici zokuphepha nezonga amandla zenza le substrate ibe ngcono kakhulu ekusetshenzisweni kwe-LED. Ukudluliswa kwe-wavelength okuhle kusiza kabanzi ngokuhlinzeka ngogesi okulungile nokudluliswa kokukhanya kuyo yonke i-chip.

Ukuqhathaniswa Okusheshayo Kwazo Zonke Izinto Ezibalulekile

Lezi zinto ezintathu zinikeza izinzuzo ezahlukahlukene lapho zisetshenziswa kuma-UV chips. Izimboni, izikhungo zokunakekelwa kwezempilo, izakhamuzi, amahhovisi, njll., zingasebenzisa izisetshenziswa ezenziwe ngalawa mashiphu wezinto ezibalulekile futhi zizuze izinzuzo ezihlukahlukene.

Ungayikhetha Kanjani I-UV LED Chip yohlelo lwakho lokusebenza?

·  Umsebenzi:  Lapho ukhetha i-UV LED, qinisekisa ukuthi isebenza kahle ngokukhulula ubude beza be-ultraviolet obufanele umsebenzi othile. Kungaba ukwelapha noma ukuvala inzalo endaweni yakho. Kufanele uhlole i-chip’s ukusebenza ngokukhetha i-voltage efanele. Bheka ubude bokuphila nokufaneleka kwe-UV LED chip ngomsebenzi othile. Izosiza ukugcina ikhwalithi, ithuthukise ukusebenza, futhi igcine ukufana kwe-LED isikhathi eside.

·  Ubude bamazunga: Ama-wavevel amaningi asebenza phakathi kuka-200nm no-400nm. Khetha i-chip enobude begagasi obufanele ukuze isebenze ngamandla afanele ukuze ikhiphe i-spectrum esebenza kahle kakhulu ngamadivayisi. Ubude begagasi obusebenziseka kakhulu kuma-LED buphakathi kuka-365nm no-395nm. Iphephile futhi inenani elincane lemisebe, futhi.

·  Kuqiza kahle: Izimboni eziningi zisebenza ngesabelomali futhi zibheke phambili kuma-LED chips angabizi kakhulu. Ngakho-ke, khetha i-chip ehambisana kahle nokusetshenziswa komsebenzi wakho. Ungayisebenzisela ukwelapha i-resin noma uyinki, ukuvala inzalo yamanzi nomoya, ukubulala amagciwane ezibhedlela, noma uphenyo lobugebengu

·  Okuphumayo Okukhanyayo: Iphrofayili yokukhipha ukukhanya kwamamojula we-UV-A, UV-B, kanye ne-UV-C kumele ihlolwe. Kufanele ukhethe ama-LED e-UV ngokuya ngokukhipha kwawo ukukhanya, okungaba mnene, okumaphakathi, noma kuqine kakhulu. Uma udinga i- I-UV LED chip yokwelapha , ungase udinge okuthile nge-LOP emnene.
