Ma UVLED, gulu laling'ono la ma light-emitting diode (LEDs), amatulutsa kuwala mkati mwa ultraviolet spectrum m'malo mwa kuwala kowoneka ngati ma LED akale. Mawonekedwe a UV amagawidwanso m'magulu atatu akuluakulu kutengera kutalika kwa mawonekedwe: UVA, UVB, ndi UVC. Mubulogu iyi, tiwona gawo lofunikira la Metal Core Printed Circuit Board (MCPCB) muukadaulo wa UVLED, kuwonetsa kufunikira kwake pakuwongolera bwino, kasamalidwe ka kutentha, komanso moyo wonse.
UVA (315-400nm):
UVA, yomwe imadziwikanso kuti pafupi-ultraviolet, imatulutsa kuwala kwa ultraviolet kwa mafunde aatali. Ili pafupi kwambiri ndi kuwala kowoneka bwino ndipo imapeza ntchito pakuchiritsa kwa UV, kusanthula kwazamalamulo, kuzindikira zabodza, mabedi otsuka khungu, ndi zina zambiri.
UVB (280-315 nm):
UVB imatulutsa kuwala kwapakati pa mafunde a ultraviolet ndipo imadziwika chifukwa chachilengedwe chake. Amagwiritsidwa ntchito pazachipatala, phototherapy, mankhwala ophera tizilombo toyambitsa matenda, komanso poyambitsa kaphatikizidwe ka vitamini D pakhungu.
UVC (100-280 nm):
UVC imatulutsa kuwala kwa ultraviolet kwanthawi yayitali ndipo ili ndi mphamvu zopha majeremusi. Ntchito zake ndi monga kuyeretsa madzi, kupha tizilombo toyambitsa matenda mumlengalenga, kutsekereza pamwamba, ndi kuthetsa mabakiteriya, ma virus ndi tizilombo tina tating'onoting'ono.
Ma UVLED amagwira ntchito mkati mwa kutentha kwa -40 ° C mpaka 100 ° C (-40 ° F mpaka 212 ° F). Komabe, ndikofunikira kudziwa kuti kutentha kwambiri kumatha kukhudza magwiridwe antchito, magwiridwe antchito, komanso moyo wa ma UVLED. Choncho, njira zoyenera zoyendetsera kutentha monga zoyikira kutentha, mapepala otentha, ndi mpweya wokwanira wa mpweya amagwiritsidwa ntchito kuti athetse kutentha ndi kusunga ma UVLED mkati mwa kutentha koyenera.
Pomaliza, MCPCB imagwira ntchito yofunika kwambiri paukadaulo wa UVLED, yopereka maubwino ofunikira monga kutentha kwachangu, kukhathamiritsa kwamafuta, kudalirika m'malo ovuta, komanso kudzipatula kwamagetsi. Makhalidwewa ndi ofunikira kwambiri pakukulitsa magwiridwe antchito a UVLED, kuwonetsetsa kuti moyo wautali, ndikusunga kutentha koyenera. Kufunika kwa MCPCB kwagona pakutha kuchita bwino, kukonza kasamalidwe ka kutentha, ndikupereka maziko odalirika a machitidwe a UVLED. Popanda MCPCB, ntchito za UVLED zikanakumana ndi zovuta pakutaya kutentha, kukhazikika kwa magwiridwe antchito, komanso chitetezo chonse.
