Ndizodziwika kwambiri kuti nyali za LED zimakhala zakuda zikagwiritsidwa ntchito. Pali zifukwa zitatu zomwe zimapangitsa kuti magetsi a LED aziyima:.
Kuyendetsa kwawonongeka
Tchipisi za LED zimafunika kuti zizigwira ntchito pamagetsi otsika a DC (pansi pa 20V), koma mphamvu zathu za mains wamba ndizokwera kwambiri AC voltage (220V AC). Kuti mutembenuzire magetsi a mains kukhala magetsi ofunikira pa tchipisi ta LED, pakufunika chipangizo chotchedwa "LED constant current driving power supply".
Mwachidziwitso, bola ngati magawo a dalaivala akufanana ndi bolodi la LED, amatha kuyendetsedwa mosalekeza ndikugwiritsidwa ntchito moyenera. Mapangidwe amkati a dalaivala ndi ovuta kwambiri, ndipo chipangizo chilichonse (monga capacitor, rectifier, etc.) chomwe sichikhoza kuchitika chingayambitse kusintha kwa magetsi, zomwe zingayambitse kuwala kwa magetsi.
Kuwonongeka kwa madalaivala ndi mtundu wofala kwambiri wa kusagwira bwino ntchito pazowunikira zowunikira za LED, zomwe nthawi zambiri zimatha kuthetsedwa mwakusintha dalaivala.
Kuwala kwa LED
LED yokha imapangidwa ndi kuphatikiza kwa mikanda yowala, ndipo ngati imodzi kapena gawo lina siliyatsa, limapangitsa kuti nyali yonseyo izizimitsidwa. Mikanda ya nyali nthawi zambiri imalumikizidwa motsatizana kenako ndikufanana - kotero ngati mkanda umodzi uyaka, zitha kupangitsa kuti mikanda isayatse.
Pamwamba pa mkanda woyaka moto pali mawanga akuda. Ipezeni ndikulumikiza waya kumbuyo kwake kuti ikhale yofupikitsa; Kapenanso, kuchotsa babu ndi watsopano kungathe kuthetsa vutoli.
Nthawi zina, LED imodzi imayaka, zitha kukhala mwangozi. Ngati zimayaka nthawi zambiri, ndiye kuti nkhani zoyendetsa ziyenera kuganiziridwa - chiwonetsero china cha kulephera kwagalimoto ndikuyaka tchipisi ta LED.
Kuwala kwa LED
Zomwe zimatchedwa kuwonongeka kwa kuwala kumatanthauza kuchepa kwa kuwala kwa thupi lowala, lomwe limawonekera kwambiri mu nyali za incandescent ndi fulorosenti.
Nyali za LED sizingapewere kuwola, koma kuwola kwawo pang'onopang'ono, ndipo nthawi zambiri kumakhala kovuta kuwona kusintha ndi maso. Koma sizinganenedwe kuti ma LED otsika kwambiri, kapena matabwa a mikanda yotsika kwambiri, kapena zinthu zomwe cholinga chake monga kutenthetsa bwino kwa kutentha zingapangitse kuti kuwola kwa kuwala kwa LED kufulumire.
