N'chifukwa chiyani magetsi otsogolera amakhala akuda?

Ndi chodabwitsa kwambiri kuti nyali za LED zimachepa kwambiri zikagwiritsidwa ntchito.Mwachidule, pali zifukwa zitatu zomwe magetsi a LED azitha kuzimitsidwa.

Kulephera kuyendetsa galimoto.

Zofunikira za nyali za LED mu DC low voltage (pansi pa 20V) zimagwira ntchito, koma mains athu omwe timakhala nawo nthawi zonse ndi AC high voltage (AC 220V).Magetsi ofunikira kuti asandutse mphamvu ya mains kukhala mkanda wa nyali amafunikira chipangizo chotchedwa "LED constant current drive power supply".

Kulankhula mongoyerekeza, malinga ngati magawo a dalaivala ndi bolodi la bead, amatha kupitiliza kugwira ntchito, kugwiritsa ntchito bwino.Mkati mwa dalaivala ndizovuta kwambiri.Kulephera kwa chipangizo chilichonse (monga capacitor, rectifier, etc.) kungayambitse kusintha kwa magetsi, zomwe zidzachititsa kuti nyali izizire.

Kuwala kwa LED.

LED yokha imapangidwa ndi kuphatikiza kwa mikanda ya nyali, ngati imodzi kapena gawo la kuwala silili lowala, liyenera kupangitsa nyali yonse kukhala mdima.Mikanda ya nyali nthawi zambiri imalumikizidwa motsatizana kenako mofanana - kotero kuti mkanda wa nyali uwotchedwa, ndizotheka kupangitsa kuti mikanda ingapo isakhale yowala.

Pamwamba pa mkanda woyaka moto pali mawanga akuda.Ipezeni ndikuyilumikiza ndi waya kumbuyo kwake kuti ikhale yofupikitsa.Kapena kusintha mkanda watsopano wa nyali, ukhoza kuthetsa vutoli.

LED nthawi zina imawotcha imodzi, mwina mwangozi.Ngati mumawotcha pafupipafupi, muyenera kuganizira zovuta za dalaivala - chiwonetsero china cha kulephera kwa dalaivala ndikuyaka kwa mkanda.

Kuwala kwa LED.

Kuwola kwa kuwala ndi pamene kuwala kwa kuwala kumakhala kochepa kwambiri - chikhalidwe chomwe chimawonekera kwambiri mu nyali za incandescent ndi fulorosenti.

Kuwala kwa LED sikungapewe kuwonongeka kwa kuwala, koma kuthamanga kwake kwa kuwola kumakhala pang'onopang'ono, nthawi zambiri ndi maso ndizovuta kuwona kusintha.Koma sizimapatula otsika LED, kapena otsika kuwala mkanda bolodi, kapena chifukwa osauka kutentha dissipation ndi zinthu zina cholinga, chifukwa LED kuwala kuchepa liwiro limakhala mofulumira.
