Kuwala kwa LED Nthawi zambiri Kuwona Zolakwika ndi Njira Zosamalira

Momwe mungakonzere kuwala kwa LED? Zhuhai amaphunzitsa aliyense kuti aphunzire kuchita. Zolakwika zosavuta za LED zimathanso kudzikonza. Nyali za LED ndizosiyana ndi nyali zam'mbuyomu za incandescent. Nyali za incandescent zimasweka kwenikweni. Kwenikweni, tungsten filaments amawotchedwa. Magetsi a LED ndi osiyana. Magetsi a LED amapangidwa ndi ma frequency a LED ndi mikanda ya nyali ya LED. Magetsi ambiri a LED amatha kukonzedwa, koma mtengo wa nyali za LED sizokwera. Zambirimbiri, kotero palibe amene amagwira ntchito yokonza magetsi a LED, mtengo wake ndi wokwera, ena sakufuna kukonzanso, mtengo wake ndi wotsika, mtengo wa ntchito ndi wotsika kwambiri, kotero ukhoza kukonzedwa ndi ogwiritsa ntchito. Momwe mungakonzere magetsi a LED ngati ogwiritsa ntchito wamba? Pali zifukwa zambiri za kulephera kwa magetsi a LED, koma pali zolephera zomwe zimakhala zosavuta. Ndibwino kuti ogwiritsa ntchito ayesetse kudzikonza okha ndikuchita ngati akuyesa. Nyali za LED nthawi zambiri zimawona zolakwika ndi njira zokonzera 1. Mikanda ya nyali ya LED imawonongeka. Uku ndi kulephera kofala kwambiri. Nthawi zambiri, mikanda ya nyali ya LED ikawotchedwa, pamakhala mawanga akuda pamwamba. Kuyang'anitsitsa mosamala kungasiyanitsidwe. Pakukonza zolakwikazi, muyenera kukonzekeretsa chitsulo cha msilikali. Koma bwanji ngati palibe mkanda wa nyali ya LED? Mutha kugwiritsa ntchito 150 ωKukaniza kumanzere ndi kumanja kumalowa m'malo, ngati woyendetsa nthawi zonse amatha kulumikizidwa mwachindunji. 2. Zosefera capacitance kulephera. Kuwala kosavuta kwa LED nthawi zambiri kumakonza magetsi a AC kudzera pakulekerera ndi kutsitsa kukanikiza, ndiyeno perekani mikanda ya nyali ya LED kudzera mu kusefa kwa capacitor. Ngati kulephera kwa fyuluta capacitor kumapangitsa kuti magetsi azikhala osakhazikika, magetsi a DC amakhala otsika, zomwe zimapangitsa kuwala kwa LED kukhala mdima. Yezerani kuchuluka kwa fyuluta capacitor ndi fayilo ya multimeter capacitor. Ngati cholakwikacho ndi chachikulu, cholakwikacho chimakhala chachikulu kuposa 30%. Zikutanthauza kuti capacitance yasokonekera. Pezani mphamvu yamagetsi ndi mphamvu yomwe ili yaikulu kuposa yofanana ndi parameter ya capacitor. 3. The capacity resistance dontho-down module yawonongeka. The capacity resistance drop drop module imakhala ndi capacitor capacitor ndi kukana kufanana. Itha kugwiritsidwa ntchito kuyesa ngati mphamvu yake ndi kukana kwake kungawonongeke. 4. Bwererani. Phatikizani kuwala kwa LED ndikuwona ngati pali cholumikizira panjira yamkati ndi mawaya otulutsa. Ngati ndi choncho, gwiritsani ntchito chitsulo chosungunuka chamagetsi kuti mukonze. 5. Kuwongolera kwa diode. Pali zolakwika monga kutsegula misewu ndi maulendo afupikitsa, omwe angayambe chifukwa cha kusefukira, kapena chifukwa cha kulephera kwa nthawi yaitali. Pezani diode yokonzanso yomwe ili ndi mphamvu yakumbuyo yamagetsi yopitilira 350V komanso yomwe ikugwira ntchito yopitilira 0.5A, monga 1N4004 1N4007, ndi zina zambiri. 6. Kulephera kwa LED kosalekeza koyendetsa galimoto. Kwa akatswiri omwe amafunikira zinachitikira pakompyuta -zokhudzana ndi mtundu uwu wa kulephera kukonza, angapeze ndodo luso la opanga Zhuhai yokonza. Wopanga amakhazikika pakupanga mikanda ya nyali ya LED. N'zodziŵika bwino kwambiri. Ndi bwino kusintha mkanda watsopano wa nyali ya LED pambuyo pa kulephera kosavuta pamwambapa.
