Za Mavuto A Tsiku ndi Tsiku a Deep Ultraviolet LED Nyali Mikanda

Za zovuta zatsiku ndi tsiku zakuya -mikanda ya nyali ya ultraviolet LED 1. Zimayamba chifukwa cha mphamvu zamagetsi: 01. Yang'anani ngati magetsi opangira magetsi ali ndi ntchito zabwinobwino, komanso ngati chowunikira chayatsidwa. Ngati sichiyatsa, chonde onani ngati magetsi alumikizidwa; 02 . Yang'anani ngati chingwe chamagetsi cha mikanda ya nyali ndi chofanana ndi mphamvu zabwino ndi zoipa za magetsi. Ngati pali chosinthira, ngati pali mavuto omwe ali pamwambapa, chonde gwirizanitsani bwino. 2. Mikanda ya nyali ya LED pazofunikira zamagetsi: Mikanda ya nyali ya LED yotchedwa 3V, kwenikweni, mitundu yosiyana imakhalanso ndi zofunika zosiyanasiyana pamafunde. Chofunikira chachikasu ndichochepa kwambiri. Ngati madziwa ndi aakulu kwambiri, pachimake chidzawotchedwa. Gwiritsani ntchito batri yowonjezereka ya 2.4V, ** ndiyosavuta kuyaka, chifukwa ngakhale magetsi si aakulu, mphamvuyi ndi yaikulu kwambiri, idzawotchedwabe pakufuna kwake. 3. Pankhani ya kuwala kwa LED kopanda mphamvu: Ngati palibe mphamvu, ngati kuli koyenera kusankha pogula, tikulimbikitsidwa kukonzekera 3V buttage batri, ndikugwiritsa ntchito batri kuti muwone mosavuta kuwala komwe LED ikutumiza. 4. Zifukwa zoyatsira mikanda yamagetsi yamphamvu kwambiri ya LED: 01. Awiri filaments chapamwamba ndi m'munsi filaments. Makampani athu amatchedwa golden line, golide weniweni. Muzu mzere, welded pa chitoliro Qina, ankagwira ntchito yokonza. 02. Kuyatsa filament kukuuzani momveka bwino kuti kuwala kwanu kwatenthedwa ndi mphamvu yayikulu, yomwe ili yofanana ndi kuchotsedwa. 03. Dalaivala wamakono wa 1W ali pafupi 350mA, ndipo mphamvu yogwiritsira ntchito pakati pa 3.2-3.6V ili pakati pa 3.2-3.6V. Chonde tcherani khutu mukagwiritsidwa ntchito. 04. Nthawi zambiri, ma aluminium-based plates of three 1W magetsi amayendetsedwa ndi pafupifupi 12V, ndipo kawirikawiri amagwiritsa ntchito 220V mwachindunji. Kodi mukuwona ngati muli ndi gwero lanthawi zonse kapena mphamvu yoyendetsa 12V? 5. Chifukwa chachikasu cha mikanda ya nyali ya LED: Chifukwa cha chikasu cha tsitsi losindikizira lakunja chimapangidwa makamaka ndi kusafananitsa kwa mtengo wa epoxy esters ndi wothandizira, koma sizinganenedwe kuti nthawi yophika chisindikizo chakunja ndichotalika kwambiri ndipo nthawi yophika ndi yayitali kwambiri. Yankho: Gulani gulu la osindikiza akunja ndi machiritso, monga mtundu wa 800 kapena 2339 guluu wamitundu yabwino yamankhwala a Shanghai, ndipo zotsatirazi zidzalipidwa pakuwongolera kupanga, kutsatira mosamalitsa ntchito zopewera nthawi yophika. motalika kwambiri kapena osakwanira, etc. , Izi ndi zabwino kwambiri. 6. Zifukwa zakutayikira kwa mikanda ya nyali ya LED: Zida zamakina sizimakhazikika, ndipo ogwira ntchito samavala chibangili chamagetsi (ayenera kukhala ndi chingwe). Electrostatic chitetezo chopangidwa sichoyenera. Kenaka, panthawi ya phukusi, mzere wowotcherera umawotchedwa, ndipo chomaliza ndi vuto la zoopsa zobisika za chip palokha. 7. Mikanda ya nyali ya LED iyenera kukhala vuto la kulolerana ndi kulemedwa kwamalingaliro: M'malo mwake, palibe mwa awiriwa, mikanda ya nyali ya LED ndi chubu chachiwiri. Pamafunika positive drive voltage kuti igwire ntchito. Nthawi zambiri Kuphatikiza apo, mawonekedwe apano amatha kuwongolera kuwala kwa nyali ya LED. Ndiko kunena kuti, mikanda ya nyali ya LED idangotembenuza mphamvu yamagetsi kukhala mphamvu yowunikira. 8. Zifukwa za kuwonongeka kwa mikanda ya nyali ya LED: Pali zifukwa zinayi zochepetsera mphamvu yaing'ono ya LED: 1: Zotchinga zachitsulo ndizosauka. Awiri: epoxy resin yellowization. Chachitatu: chip ndi mabulaketi sizolimba mokwanira. Chachinayi: Chip ndi kuchepetsa. Ngati ndi kuwala koyera, pali vuto la attenuation wa fulorosenti ufa.
