Ma LED amagetsindi njira yotchuka yowunikira chifukwa cha mphamvu zawo zambiri, moyo wawo wautali, komanso kuwala kwawo kwapadera. Koma kodi munayamba mwadzifunsapo momwe magetsi odabwitsawa amapangira? Munkhaniyi, tifufuza njira zopangira magetsi a LED ndi zinthu zomwe zimapangitsa kuti agwire ntchito bwino.
Gawo loyamba popanga nyali ya LED ndikusankha zinthu zoyenera. Zinthu zazikulu zomwe zimagwiritsidwa ntchito ndi ma LED apamwamba kwambiri, zida zamagetsi, ndi zotenthetsera za aluminiyamu. Chip ya LED ndiye mtima wa nyali ya LED ndipo nthawi zambiri imapangidwa ndi zinthu za semiconductor monga gallium arsenide kapena gallium nitride. Zinthuzi zimatsimikizira mtundu womwe LED imatulutsa. Zinthuzo zikapezeka, njira yopangira imatha kuyamba.
Ma chips a LED amaikidwa pa bolodi la circuit, lomwe limadziwikanso kuti PCB (bolodi la circuit losindikizidwa). Bolodi limagwira ntchito ngati gwero lamagetsi la ma LED, kulamulira mphamvu kuti magetsi azigwira ntchito bwino. Ikani solder paste pa bolodi ndikuyika LED chip pamalo osankhidwa. Kenako cholumikizira chonsecho chimatenthedwa kuti chisungunuke solder paste ndikusunga chip pamalo ake. Njirayi imatchedwa reflow soldering.
Gawo lotsatira lofunika kwambiri la kuwala kwa LED ndi kuwala kwa optics. Optics zimathandiza kulamulira njira ndi kufalikira kwa kuwala komwe kumatulutsidwa ndi ma LED. Ma lens kapena zowunikira nthawi zambiri zimagwiritsidwa ntchito ngati zinthu zowunikira. Ma lens ndi omwe amachititsa kuti kuwala kusinthe, pomwe magalasi amathandiza kutsogolera kuwala m'njira zinazake.
Pambuyo poti ma chip a LED ndi ma optics atha, ma electronic circuitry amaphatikizidwa mu PCB. Dera ili limapangitsa kuti floodlight igwire ntchito, zomwe zimathandiza kuti izimitse ndi kuzimitsa ndikulamulira kuwala. Ma LED floodlight ena alinso ndi zina zowonjezera monga masensa oyenda kapena mphamvu zowongolera kutali.
Kuti apewe kutentha kwambiri, magetsi a LED amafunika malo otenthetsera. Malo otenthetsera nthawi zambiri amapangidwa ndi aluminiyamu chifukwa cha kutentha kwake kwabwino kwambiri. Amathandiza kuchotsa kutentha kochuluka komwe kumapangidwa ndi ma LED, kuonetsetsa kuti amakhala nthawi yayitali komanso amagwira ntchito bwino. Malo otenthetsera amayikidwa kumbuyo kwa PCB ndi zomangira kapena thermal paste.
Zigawo zosiyanasiyana zikasonkhanitsidwa ndikuphatikizidwa, nyumba zosungiramo magetsi zimawonjezedwa. Chikwamacho sichimangoteteza zigawo zamkati zokha komanso chimapereka kukongola. Malo osungira nthawi zambiri amapangidwa ndi aluminiyamu, pulasitiki, kapena kuphatikiza ziwirizi. Kusankha zinthu kumadalira zinthu monga kulimba, kulemera, ndi mtengo.
Kuyesa bwino kwambiri khalidwe la nyali za LED zomwe zasonkhanitsidwa zikufunika musanayambe kugwiritsa ntchito. Mayesowa amatsimikizira kuti nyali iliyonse ikukwaniritsa miyezo yodziwika bwino pankhani ya kuwala, kugwiritsa ntchito mphamvu, komanso kulimba. Nyalizi zimayesedwanso m'malo osiyanasiyana, kuphatikizapo kutentha ndi chinyezi, kuti zitsimikizire kuti zimagwira ntchito bwino m'malo osiyanasiyana.
Gawo lomaliza pakupanga ndi kulongedza ndi kugawa. Magetsi a LED amapakidwa mosamala ndi zilembo zotumizira. Kenako amagawidwa kwa ogulitsa kapena mwachindunji kwa ogula, okonzeka kuyikidwa ndikupereka kuwala kowala komanso kothandiza pazinthu zosiyanasiyana, kuphatikizapo mabwalo amasewera, malo oimika magalimoto, ndi nyumba.
Mwachidule, njira yopangira magetsi a LED imaphatikizapo kusankha mosamala zinthu, kusonkhanitsa, kuphatikiza zinthu zosiyanasiyana, ndi kuyesa kokhwima kwa khalidwe. Njirayi imatsimikizira kuti chinthu chomaliza ndi njira yabwino kwambiri yowunikira, yothandiza, komanso yolimba. Magetsi a LED akusintha nthawi zonse kuti apereke magwiridwe antchito abwino komanso magwiridwe antchito, ndipo njira zawo zopangira zimagwira ntchito yofunika kwambiri kuti apambane mumakampani opanga magetsi.
Zomwe zili pamwambapa ndi njira yopangira magetsi a LED. Ngati mukufuna, takulandirani kuti mulumikizane ndi kampani yogulitsa magetsi a LED ku Tianxiang.Werengani zambiri.
