Izici Nokuthuthukiswa Kwemithombo Yokukhanya kwe-UV LED

Umthombo wokukhanya we-UV LED, okuyisifinyezo se-ultraviolet light emitting diode. Ngokombono wempilo yomuntu kanye nomthelela wemvelo, singakwazi ukwehlukanisa ukukhanya okunsomi ngokuya kobude begagasi be-wavelength: I-UV (ukukhanya okunsomi): ukukhanya okukhanyayo okunsomi okubonakalayo (400-420nm) ) I-UVA (315 400nm), eyaziwa nangokuthi yinde wave ukukhanya okunsomi noma "ukukhanya okumnyama". .. Imithombo yokukhanya ye-UV LED, okungukuthi, isifinyezo se-ultraviolet light emitting diode. Ngokombono wempilo yomuntu kanye nomthelela wemvelo, singakwazi ukuhlukanisa ukukhanya okunsomi kuye ngobude begagasi. 400-420nm) UVA (315 400nm), eyaziwa nangokuthi igagasi elide onsomi noma "ukukhanya okumnyama". I-UVB (280 315nm), eyaziwa nangokuthi amagagasi aphakathi ukukhanya okunsomi. I-UVC (200 280nm), eyaziwa nangokuthi i-short-wave purple light noma inzalo yokukhanya okunsomi. I-UVD: I-Vacuum UV (100-200nm) Ukukhanya kwelanga kuqukethe ukukhanya kwe-UVA, i-UVB, kanye ne-UVC ye-ultraviolet kumabhande amathathu, kodwa ngenxa yokumuncwa kwezingqimba ze-ozone emoyeni, u-99% wokukhanya kwe-UV phansi usebhandeni le-UVA iqembu le-UVA. I-UV LED ngokuvamile ibhekisela kuma-LED angaphansi kuka-400nm phakathi nendawo yokukhanya, kodwa ngezinye izikhathi ibizwa ngokuthi eduze ne-ultraviolet LED lapho igagasi elikhazimulayo likhulu kuno-380nm, nalapho lifushane kuno-300nm. I-UV LED (UV LED) isetshenziswa kakhulu emikhakheni yokuhlonza i-biomedical, anti-counterfeiting, ukuhlanzwa (amanzi, umoya, njll.), ukugcinwa kwedatha yekhompyutha kanye nezempi. Futhi ngokuthuthukiswa kobuchwepheshe, izinhlelo zokusebenza ezintsha zizoqhubeka nokuvela esikhundleni sobuchwepheshe bokuqala nemikhiqizo. Ama-LED e-UV anethuba elibanzi lokufaka isicelo semakethe. Isibonelo, amathuluzi we-UV LED phototherapy angamadivayisi ezokwelapha aziwa kakhulu esikhathini esizayo, kodwa ubuchwepheshe bamanje busesekhona esikhathini esizayo. Isikhathi sokukhula. I-UV LED ithola ukunakwa okusabalele kubakhiqizi bezinto zokukhanyisa nabakhiqizi be-LCD bokubonisa. Ngoba ngokusebenzisa ukukhanya kwe-ultraviolet nokuguqula ukukhanya kwe-ultraviolet kube izinto ze-fluorescent ezibomvu, eziluhlaza okwesibhakabhaka, kungenzeka ukufeza i-LED emhlophe enombala oqinile wokuzala. Njengamanje, iningi lama-LED amhlophe atholakala ngokwentengiso asebenzisa ama-LED aluhlaza nezinto ezibonakalayo ze-fluorescent eziguqula ukukhanya okuluhlaza kube ukukhanya okuphuzi. Izingxenye zesibani esibomvu zibuthakathaka. Uma ikhanyisa ukukhanya okumhlophe ezintweni ezibomvu, izobonisa iwolintshi elibuthakathaka. Uma ufuna ukuyisebenzisela isibani sangemuva, kufanele uthole indlela kusihlungi sombala. Kodwa uma ultraviolet LED, ungakwazi ukuxazulula lezi zinkinga. Kodwa-ke, ngenxa yokuthi ukukhanya okukhipha ukukhanya kwe-ultraviolet LED kucishe kube ngehhafu kunemikhiqizo ye-LED eluhlaza okwesibhakabhaka, ukukhanya sekuyisihloko esikhulu se-ultraviolet LED.
