Mafuta osefukirandi kusankha kokongola kwambiri chifukwa cha mphamvu zawo zambiri, moyo wautali, komanso kuwala kwapadera. Koma kodi mudayamba mwadzifunsapo kuti magetsi odabwitsa awa amapangidwa bwanji? Munkhaniyi, tifufuze zopanga zosefukira za ku LED ndi zigawo zomwe zimapangitsa kuti azigwira bwino ntchito.
Gawo loyamba popanga madzi osefukira akusankha zoyenera. Zipangizo zazikuluzikulu zomwe zimagwiritsidwa ntchito ndizomwe zimapangidwa ndi matope ambiri, zigawo zamagetsi, ndi aluminium kutentha kumagwera. Chip a LED ndi mtima wamadzi osefukira ndipo nthawi zambiri amapangidwa ndi zida za semiconductor monga gallium arnide kapena gallium nitride. Zinthuzi zimazindikira kuti utoto womwe udayambika. Zipangizozo zikapezeka, njira yopangira imatha kuyamba.
Traps ya LED imayikidwa pabwalo lamadera, lomwe limadziwikanso ngati PCB (gulu ladera losindikizidwa). Gululo limakhala ngati gwero lamphamvu kwa matikiti, kuwongolera zomwe zimapangitsa kuti magetsi aziyendetsa bwino. Ikani walonda pa bolodi ndi kuyika chip mu gawo losankhidwa. Msonkhano wonsewo umatenthedwa kuti usungunuke wogulitsayo ndikugwira mbewa m'malo mwake. Njirayi imatchedwa kuti ikonzedwe mwachangu.
Gawo lotsatira lotsatira la kusefukira kwa LED ndi zopsa. Opticcs amathandizira kuwongolera malangizowo ndikufalikira kwa kuwala komwe kumatulutsidwa ndi ma LED. Magalasi kapena owonetsera nthawi zambiri amagwiritsidwa ntchito ngati zinthu zowala. Magalasi ali ndi udindo wopanga choyezeracho, pomwe magalasi amathandizira kuwongolera kuti aziwunika.
Pambuyo pa msonkhano wa LED Chip ndi otembenuka ndi athunthu, madera amagetsi amaphatikizidwa mu PCB. Gawoli lipangitsa kuti madziwo azigwira ntchito, ndikulola kuti zitseguke ndikuwongolera kuwala. Magetsi ena osefukira amaphatikizanso zochitika zina monga masensa kapena mphamvu yakutali.
Pofuna kupewa kutentha, magetsi osefukira amafunika kutentha. Kutentha kumamizidwa nthawi zambiri kumapangidwa ndi aluminiyam chifukwa cha mawonekedwe ake abwino kwambiri. Zimathandizira kusungunula kutentha kwambiri ndi ma LED, kuwonetsetsa kuti ndi moyo wawo wokhathanzi ndi kuchita bwino. Kutentha kwa kutentha kumayikidwa kumbuyo kwa PCB yokhala ndi zomangira kapena mafuta otenthetsera.
Zidazo zikangosonkhana ndikuphatikizidwa, maufulu osefukira adawonjezeredwa. Mlanduwo sikuti amangoteteza zinthu zamkati komanso kumapereka zokondweretsa. Zikwangwani nthawi zambiri zimapangidwa ndi aluminiyamu, pulasitiki, kapena kuphatikiza kwa awiriwo. Kusankha zinthu zakuthupi kumadalira zinthu monga kulimba, kulemera, ndi mtengo.
Kuyeserera kokwanira kokwanira kumafunikira kuti malo osefukira a LED omwe agwedezeka asanakomere ntchito. Mayeso awa akuwonetsetsa kuti malo odziguwa aliwonse amakumana ndi miyezo yotchulidwa malinga ndi kuwala, mphamvu, ndi kulimba. Magetsi amayesedwanso m'malo osiyanasiyana, kuphatikiza kutentha ndi chinyezi, kuonetsetsa kudalirika kwawo.
Gawo lomaliza munjira yopanga ndi kunyamula ndi kugawa. Magetsi osefukira amasungidwa mosamala ndi zilembo zotumizira. Kenako amagawidwa kwa ogulitsa kapena mwachindunji kwa ogula, okonzeka kukhazikitsa ndikuwunikira zowunikira zowala zosiyanasiyana, kuphatikizapo minda yamasewera, maenje oyimika, ndi nyumba zoimikapoma.
Zonsezi, zomwe zimapangidwira kuti madzi osefuzi osefukira pamafunika kusankha bwino zinthu, msonkhano, kuphatikiza ndi zigawo zosiyanasiyana, komanso kuyezetsa kokhazikika. Njirayi imatsimikizira kuti chinthu chomaliza ndi chofunikira kwambiri, chothandiza, komanso chopeputsa. Magetsi osefukira amasintha nthawi zonse kuti agwiritse ntchito bwino ntchito komanso magwiridwe antchito, ndipo njira zawo zopanga zimathandiza gawo lofunikira pakuchita bwino pantchito yowunikira.
Zomwe zili pamwambazi ndizopanga zosefukira za ku LED. Ngati mukufuna, talandilidwa kulumikizana kuti mulumikizane ndi magud olima osefukira tiaxiang kutiWerengani zambiri.
