Oremark UV Bead Kapangidwe

Kodi anthu ambiri angafune kudziwa kapangidwe ka mkati mwa mikanda ya nyali ya diode? N'chimodzimodzinso ndi Xiaobian, kotero ndidapempha mwapadera akatswiri kuti asonkhanitse zambiri ngati izi kuti zikufotokozereni. UV kuwala diode amatanthauza. Kuwala kwa Ultraviolet nthawi zambiri kumagwiritsidwa ntchito kuti azindikire ngati ma banknotes ndi zabodza, ndipo zinthu zina zowunikira za ultraviolet diode ndizodziwika kwambiri pamakalabu ausiku ndi maphwando. Amagwiritsidwa ntchito kupanga zinthu za fulorosenti kutulutsa kuwala kowala kwambiri. Kapangidwe kake kamene kamapangidwa ndi semiconductor yonyezimira yamagetsi, yoyikidwa pa shelefu yotsogola, kenako ndikusindikiza ndi utomoni wa epoxy mozungulira kuti muteteze waya wamkati. Chotero. Gawo lalikulu la diode yotulutsa ndi chip chopangidwa ndi P -type semiconductor ndi N -type semiconductor. Pali kusintha kosanjikiza pakati pa P -type semiconductor ndi N -type semiconductor, yotchedwa PN knot. Mu mfundo ya PN ya zipangizo zina za semiconductor, katundu waung'ono -in -load ndi chonyamulira ambiri amamasulidwa pamene chonyamuliracho chimatulutsidwa mu mawonekedwe a kuwala, kotero kuti mphamvu yamagetsi imasinthidwa mwachindunji ku mphamvu ya kuwala kwa mphamvu ya kuwala. Pn knot kuphatikiza voliyumu yosinthira, chonyamulira chochepa chimakhala chovuta kubaya, kotero sichimatulutsa kuwala. Diode iyi yopangidwa ndi jekeseni wowunikira ma electrophoretic amatchedwa luminous diode, yomwe imadziwika kuti LED. Zikagwira ntchito bwino (ndiko kuti, malekezero awiriwo kuphatikiza voteji yabwino), magetsi apano amachokera ku anode ya LED kupita ku cathode, makristalo a semiconductor amatulutsa kuwala kuchokera ku ultraviolet kupita ku mtundu wa infuraredi. The luso makhalidwe a ultraviolet kuwala diode; 1) Kuwala kofiirira kwa 5mm kumagwiritsa ntchito zoyika magalasi ndi zipolopolo za nickel-plated alloy, zomwe zimathandiziranso kuyatsa bwino kwa kuwala kofiirira, kuchepetsa kuola kwa kuwala kofiirira, kumawonjezera moyo wautumiki, ndikukulitsa moyo wautumiki. 2) Zikhomo ziwiri zimagwiritsa ntchito luso la golide. 3) Mphamvu zapamwamba zamaganizo. 4) Khalidwe lokhazikika komanso lodalirika.
