Iimpawu kunye noPhuhliso lweMithombo yokukhanya kwe-UV ye-LED

Umthombo wokukhanya we-UV LED, isifinyezo se-ultraviolet ukukhanya kwe-diode. Ngokwembono yempilo yabantu kunye neempembelelo zokusingqongileyo, sinokwahlula ukukhanya okumfusa ngokobude bobude be-wavelength: UV (ukukhanya okumfusa): ukukhanya okubonakalayo okumfusa (400-420nm) ) UVA (315 400nm), eyaziwa ngokuba bude wave ukukhanya omfusa okanye "ukukhanya okumnyama". .. Imithombo yokukhanya ye-UV ye-LED, oko kukuthi, isifinyezo se-ultraviolet light emit diode. Ngokombono wempilo yabantu kunye neempembelelo zokusingqongileyo, sinokwahlula ukukhanya okumfusa ngokobude bobude. 400-420nm) UVA (315 400nm), ekwabizwa ngokuba ngamaza amaza amfusa okanye "ukukhanya okumnyama". I-UVB (280 315nm), ekwabizwa ngokuba ngamaza aPhakathi okukhanya okumfusa. I-UVC (200 280nm), ekwabizwa ngokuba yi-short-wave purple light okanye inzala emfusa. I-UVD: I-Vacuum UV (100-200nm) Ukukhanya kwelanga kuqulethe i-UVA, i-UVB, kunye nokukhanya kwe-UVC ye-UVC kwiibhanti ezintathu, kodwa ngenxa yokufunxwa kocweyo lwe-ozone emoyeni, i-99% yesibane se-UV emhlabeni sikwibhanti ye-UVA ngaphakathi. ibhendi ye-UVA. I-LED ye-UV ngokubanzi ibhekisa kwii-LED ezingaphantsi kwe-400nm embindini wokukhanya, kodwa ngamanye amaxesha ibizwa ngokuba kufutshane ne-ultraviolet LED xa i-wave ekhanyayo inkulu kune-380nm, kwaye xa imfutshane kune-300nm. I-UV LED (i-UV LED) isetyenziswa kakhulu kwiinkalo ze-biomedical, i-anti-counterfeiting identification, ukuhlanjululwa (amanzi, umoya, njl.), ukugcinwa kwedatha yekhompyutha kunye nomkhosi. Kwaye ngophuhliso lwetekhnoloji, izicelo ezitsha ziya kuqhubeka ukubonakala zithatha indawo yetekhnoloji yokuqala kunye neemveliso. Ii-LED ze-UV zinethemba elibanzi lesicelo semarike. Ngokomzekelo, izixhobo ze-UV ze-phototherapy ze-LED zithandwa kakhulu kwizixhobo zonyango kwixesha elizayo, kodwa iteknoloji yangoku isekho ngoku kwixesha elizayo. Ixesha lokukhula. I-UV LED ifumana ingqwalasela ebanzi evela kubavelisi bezixhobo zokukhanyisa kunye nabavelisi be-LCD bomboniso. Ngenxa yokuba ngokusebenzisa ukukhanya kwe-ultraviolet kunye nokuguqula ukukhanya kwe-ultraviolet kwizinto ezibomvu, eziluhlaza, kunye ne-blue fluorescent, kunokwenzeka ukufezekisa i-LED emhlophe kunye nokuveliswa kombala oqinileyo. Okwangoku, uninzi lwee-LED ezimhlophe ezithengiswayo zisebenzisa ii-LED eziluhlaza kunye nezixhobo ze-fluorescent eziguqula ukukhanya okuluhlaza kube ukukhanya okutyheli. Amacandelo okukhanya okubomvu anamandla. Xa kukhanyisa ukukhanya okumhlophe kwizinto ezibomvu, kuya kubonisa i-orange ebuthakathaka. Ukuba ufuna ukuyisebenzisela isibane esingasemva, kufuneka ufumane indlela kwisihluzi sombala. Kodwa ukuba i-ultraviolet LED, unokusombulula ezi ngxaki. Nangona kunjalo, ngenxa yokuba ukukhanya-okukhupha ukukhanya kwe-ultraviolet LED kungaphantsi kwesiqingatha kuneemveliso ze-LED eziluhlaza, ukukhanya kuye kwaba sisihloko esikhulu se-ultraviolet LED.
