Magetsi a LEDndizosankha zowunikira zodziwika bwino chifukwa cha mphamvu zawo zambiri, moyo wautali, komanso kuwala kwapadera. Koma kodi munayamba mwadzifunsapo mmene kuwala kodabwitsa kumeneku kumapangidwira? M'nkhaniyi, tiwona njira yopangira magetsi a LED ndi zigawo zomwe zimapangitsa kuti azigwira ntchito bwino.
Gawo loyamba popanga kuwala kwa LED ndikusankha zinthu zoyenera. Zida zazikulu zomwe zimagwiritsidwa ntchito ndi ma LED apamwamba kwambiri, zida zamagetsi, ndi zoyatsira kutentha za aluminiyamu. Chip cha LED ndi mtima wa kuwala kwamadzi ndipo nthawi zambiri amapangidwa ndi zida za semiconductor monga gallium arsenide kapena gallium nitride. Zida izi zimatsimikizira mtundu wopangidwa ndi LED. Zida zikapezeka, njira yopangira ikhoza kuyamba.
Tchipisi za LED zimayikidwa pa bolodi lozungulira, lomwe limadziwikanso kuti PCB (bodi losindikizidwa). Bungweli limagwira ntchito ngati gwero lamagetsi la ma LED, kuwongolera zomwe zikuchitika kuti magetsi azigwira bwino ntchito. Ikani phala la solder pa bolodi ndikuyika chipangizo cha LED pamalo omwe mwasankhidwa. Msonkhano wonsewo umatenthedwa kuti usungunuke phala la solder ndikugwira chip pamalo ake. Njirayi imatchedwa reflow soldering.
Chigawo chotsatira chachikulu cha kuwala kwa LED ndi kuwala. Ma Optics amathandizira kuwongolera komwe akulowera komanso kufalikira kwa kuwala kotulutsidwa ndi ma LED. Ma lens kapena zowunikira nthawi zambiri zimagwiritsidwa ntchito ngati zinthu zowunikira. Magalasi ndi omwe ali ndi udindo wosiyanitsa kuwala kwa kuwala, pomwe magalasi amathandizira kuwunikira mbali zina.
Pambuyo pa msonkhano wa chip wa LED ndi optics watha, zozungulira zamagetsi zimaphatikizidwa mu PCB. Derali limapangitsa kuti floodlight igwire ntchito, kuwalola kuyatsa ndi kuzimitsa ndikuwongolera kuwala. Magetsi ena osefukira a LED amaphatikizanso zina zowonjezera monga masensa oyenda kapena mphamvu zakutali.
Pofuna kupewa kutenthedwa, nyali za kusefukira kwa LED zimafunikira masitima otentha. Masinki otentha nthawi zambiri amapangidwa ndi aluminiyamu chifukwa cha kutenthetsa kwake kwabwino kwambiri. Zimathandizira kuchotsa kutentha kwakukulu kopangidwa ndi ma LED, kuwonetsetsa moyo wawo wautali komanso kuchita bwino. Choyimitsira kutentha chimayikidwa kumbuyo kwa PCB ndi zomangira kapena phala lotentha.
Zigawo zosiyana siyana zitasonkhanitsidwa ndikuphatikizidwa, nyumba zamadzimadzi zinawonjezeredwa. Mlanduwu sumangoteteza zigawo zamkati komanso umapereka aesthetics. Zotsekera nthawi zambiri zimapangidwa ndi aluminiyamu, pulasitiki, kapena kuphatikiza ziwirizi. Kusankha zinthu kumadalira zinthu monga kulimba, kulemera, ndi mtengo.
Kuyesedwa koyenera koyang'anira bwino kumafunika magetsi a LED asanayambe kugwiritsidwa ntchito. Mayeserowa amaonetsetsa kuti kuwala kwa madzi osefukira kumakwaniritsa miyezo yodziwika bwino yowala, kugwiritsa ntchito mphamvu, komanso kulimba. Magetsi amayesedwanso m'malo osiyanasiyana, kuphatikizapo kutentha ndi chinyezi, kuti atsimikizire kudalirika kwawo muzochitika zosiyanasiyana.
Gawo lomaliza pakupanga ndikuyika ndikugawa. Kuwala kwa Chigumula cha LED kumapakidwa mosamala ndi zilembo zotumizira. Kenaka amagawidwa kwa ogulitsa kapena mwachindunji kwa ogula, okonzeka kukhazikitsa ndi kupereka kuwala kowala komanso koyenera kwa ntchito zosiyanasiyana, kuphatikizapo masewera a masewera, malo oimika magalimoto, ndi nyumba.
Zonsezi, kupanga kwa magetsi a LED kumaphatikizapo kusankha mosamala zipangizo, kusonkhanitsa, kuphatikiza zinthu zosiyanasiyana, komanso kuyesa kulamulira khalidwe labwino. Njirayi imatsimikizira kuti chomalizacho ndi chowunikira chapamwamba, chothandiza, komanso chokhalitsa. Magetsi a LED amasintha nthawi zonse kuti apereke magwiridwe antchito ndi magwiridwe antchito, ndipo njira zawo zopangira zimathandizira kwambiri pakupambana kwawo pakuwunikira.
Zomwe zili pamwambazi ndizopanga njira zopangira magetsi a LED. Ngati muli ndi chidwi ndi izi, talandiridwa kuti mulumikizane ndi othandizira osefukira a Tianxiang kutiWerengani zambiri.
