Ama-UVLED, isethi engaphansi yama-light-emitting diode (ama-LED), akhipha ukukhanya ngaphakathi kwe-ultraviolet spectrum esikhundleni sokukhanya okubonakalayo njengama-LED avamile. I-spectrum ye-UV iphinde ihlukaniswe yaba izigaba ezintathu eziyinhloko ngokusekelwe kubude begagasi: i-UVA, i-UVB, ne-UVC. Kule bhulogi, sizohlola indima ebalulekile ye-Metal Core Printed Circuit Board (MCPCB) kubuchwepheshe be-UVLED, sigqamisa ukubaluleka kwayo ekuthuthukiseni ukusebenza kahle, ukuphathwa kokushisa, kanye nempilo yonke.
I-UVA (315-400nm):
I-UVA, eyaziwa nangokuthi i-close-ultraviolet, ikhipha ukukhanya kwe-ultraviolet kwamaza amade. Iseduze ne-spectrum yokukhanya ebonakalayo futhi ithola izinhlelo zokusebenza ekwelapheni kwe-UV, ukuhlaziywa kwe-forensic, ukutholwa komgunyathi, imibhede yokushuka, nokuningi.
I-UVB (280-315 nm):
I-UVB ikhipha ukukhanya kwe-ultraviolet kwamagagasi aphakathi futhi yaziwa ngemiphumela yayo yezinto eziphilayo. Isetshenziselwa ukwelashwa, i-phototherapy, izinhlelo zokusebenza zokubulala amagciwane, ngisho nasekufakeni ukwakheka kwe-vitamin D esikhumbeni.
I-UVC (100-280 nm):
I-UVC ikhipha ukukhanya kwe-ultraviolet kwamaza amafushane futhi inezinto ezinamandla zokubulala amagciwane. Izicelo zayo zihlanganisa ukuhlanzwa kwamanzi, ukubulala amagciwane komoya, ukuvala inzalo ebusweni, nokuqeda amagciwane, amagciwane, nezinye izinto ezincane.
Ama-UVLED ngokuvamile asebenza ngaphakathi kwebanga lokushisa elingu -40°C kuya ku-100°C (-40°F kuya ku-212°F). Kodwa-ke, kubalulekile ukuqaphela ukuthi ukushisa okudlulele kungaba nomthelela ekusebenzeni, ukusebenza kahle, nempilo yokuphila kwama-UVLED. Ngakho-ke, amasu afanelekile okulawula okushisayo njengamasinki okushisa, amaphedi okushisa, nokugeleza komoya okwanele avame ukusetshenziswa ukuze kuqedwe ukushisa futhi kugcinwe ama-UVLED ngaphakathi kwebanga lokushisa elilungile.
Sengiphetha, i-MCPCB idlala indima ebalulekile kubuchwepheshe be-UVLED, ihlinzeka ngezinzuzo ezibalulekile njengokulahlwa kokushisa okusebenzayo, ukuqhutshwa kwe-thermal okuthuthukisiwe, ukwethembeka ezindaweni ezinokhahlo, kanye nokuhlukaniswa kukagesi. Lezi zimfanelo zibalulekile ekukhuliseni ukusebenza kwe-UVLED, ukuqinisekisa ukuphila isikhathi eside, nokugcina izinga lokushisa elilungile lokusebenza. Ukubaluleka kwe-MCPCB kusemandleni ayo okuthuthukisa ukusebenza kahle, ukuthuthukisa ukuphathwa kokushisa, nokuhlinzeka ngesisekelo esithembekile samasistimu e-UVLED. Ngaphandle kwe-MCPCB, izinhlelo zokusebenza ze-UVLED zingabhekana nezinselele ekulahlekeni kokushisa, ukuqina kokusebenza, nokuphepha kukonke.
