UVLED's Chikumbiro Munda uye Dziviriro Matambudziko

Urefu hwemwaranzi yeultraviolet iri pakati pechiedza chinooneka neX-ray. Kureba kwayo kwewavelength ndeye 10 kusvika 400nm. Nekudaro, vazhinji vanogadzira mafotoelectric vanotenda kuti wavelength ye430nm iriwo ultraviolet. Kunyangwe mirazvo yakawanda yeultraviolet isingaonekwe nevanhu, ichiri kupihwa mazita eiyo generator spectrum yeimwe Violet. UV LED yakafambira mberi zvikuru mumakore mashoma apfuura. Izvi hazvisi chete mhedzisiro yekufambira mberi kwetekinoroji yeyakasimba-state UV mudziyo, asiwo nekuda kwekuwedzera kwekuda kwemwenje weUV unoburitsa nharaunda dzisina njodzi. Ikozvino UV LED inopa pamusika weoptoelectronics ine wavelength renji ye265 kusvika 420nm. Kune akawanda mafomu ekurongedza, senge perforation, kuisirwa pamusoro uye COB. UV LED jenareta ine akasiyana akasiyana ekushandisa. Nekudaro, jenareta yega yega yakazvimirira muwavelength uye simba rekubuda. Kazhinji, UV mwenje unoshandiswa pa LED unogona kukamurwa kuita minda mitatu. Iwo anotsanangurwa seUV-A (refu wave ultraviolet), UV-B (yepakati wave ultraviolet) uye U V-C (pfupi wave ultraviolet). UV A mudziyo wakagadzirwa kubva 1990. Aya ma LED anowanzo shandiswa mukunyepedzera kuyedzwa kana kuisirwa (mari, rezinesi rekutyaira kana faira, nezvimwewo). Izvo zvinodiwa zvemagetsi zvekushandisa izvi zvakaderera zvakanyanya. Iwo chaiwo wavelength renji iri mukati me390 kusvika 420N m. Zvigadzirwa zvakaderera zvewavelength hazvina kukodzera kushandiswa. Nekuti aya maLED 'akareba hupenyu kutenderera uye nyore kugadzira mumusika anogona kushandiswa seakasiyana emwenje masosi uye yakachipa UV zvigadzirwa. Iyo UVA LED chikamu chikamu chakakura zvakanyanya mumakore mashoma apfuura. Zvizhinji zveiyi wavelength range (inenge 350 390nm) kugadzirwa kwezvinhu zvekutengesa uye zvemaindasitiri, zvakaita seanonamira, machira, neingi. Nekuda kwekuvandudzwa kwehunyanzvi, kuderera kwemutengo, uye miniaturization, mwenje we LED ane zvakanakira kupfuura zvechinyakare solidification tekinoroji, senge mercury kana mwenje wefluorescent. Naizvozvo, iyo ketani yekugovera inogara ichikurudzira kushandiswa kweiyo LED tekinoroji, ichiita kuti maitiro ekuomesa ma LED awedzere kujeka. Kunyangwe mutengo weiyi wavelength renji wakakwira zvakanyanya kupfuura uya weUV A, kukurumidza kufambira mberi kwehunyanzvi hwekugadzira uye kuwedzera kwakasimba kwegoho kuri kudzikisa mutengo zvishoma nezvishoma. Iyo yakaderera UV A uye yepamusoro UV B wavelength renji (inenge 300-350nm) inzvimbo ichangoburwa kutengeswa. Aya mahombe anokwanisa maturusi akakodzera kune akawanda maapplication, anosanganisira ultraviolet kurapwa, biomedical, DNA kuongororwa, uye akasiyana marudzi ekunzwa. Pane kupindirana kwakakosha mune idzi 3 UV spectral renji. Nokudaro, pakusarudza, haufaniri kungofunga kuti ndeipi inonyanya kukodzera kushandiswa, asi unodawo kufunga kuti ndeipi iyo inonyanya kudhura-inoshanda mhinduro. Nekuti yakaderera wavelengths kazhinji zvinoreva yakakwirira LED mutengo. UV B uye UV C wavelength renji (anenge 250-300nm) yakakura nhanho padanho rekutanga. Nekudaro, kushingaira uye kudiwa kwekushandisa zvigadzirwa zvakadaro kumhepo uye mvura yekuchenesa system yakasimba kwazvo. Parizvino, makambani mashoma chete ane kugona kugadzira UV ma LED mukati meiyi wavelength renji, uye kunyangwe makambani mashoma anogona kugadzira zvigadzirwa zvine hupenyu hwakakwana, kuvimbika uye maitiro ekuita. Naizvozvo, mutengo weUVC/B mudziyo uchiri wakanyanya kukwirira, uye zvakaoma kushandisa mune mamwe maapplication. Mubvunzo wakajairika nezve UV LED ndewekuti: Vachaunza njodzi dzakavanzika dzekuchengetedza? Sezvambotaurwa pamusoro, UV mwenje ine akawanda mazinga. Iyo inonyanya kushandiswa UV mwenje sosi igirobhu dema. Ichi chigadzirwa chave chichishandiswa kwemakumi emakore. Inoshandiswa kugadzira mwenje kana fluorescent mhedzisiro yemaposta, pamwe nekusimbisa pendi uye mari. Chiedza chinogadzirwa neaya magirobhu chinowanzo mu UV A spectrum, padyo nemasaisai emwenje anooneka uye simba rakaderera. Kunyangwe kuratidzwa kwakanyanya kwakaratidza kuve kune hukama negomarara reganda uye mamwe matambudziko angangoitika, akadai sekukurumidza kuchembera kweganda, iyo UVA spectrum ndiyo yakachengeteka mune matatu UV mwenje. UV C uye yakawanda UV B mwenje inonyanyo shandiswa kuuraya utachiona uye kuuraya utachiona. Aya mawavelength echiedza haangokuvadzi kune ma microorganisms. Aya magetsi e LED anofanirwa kugara akavharwa, uye haafanire kutarisa zvakananga maziso asina kupfeka, kunyangwe achipenya zvishoma. Kuratidzwa muchiedza cheaya mafungu anogona kukonzera kenza yeganda uye kurasikirwa kwekuona kwechinguva kana zvachose kana kurasikirwa.
