Ndizochitika zodziwika bwino kuti nyali zotsogola zimakhala zakuda komanso zakuda pamene zimagwiritsidwa ntchito.Fotokozani mwachidule zifukwa zomwe zingadetse nkhawaKuwala kwa LED, zomwe sizili kanthu koma mfundo zitatu zotsatirazi.

1.Yendetsani kuwonongeka

Mikanda ya nyali ya LED imayenera kugwira ntchito pamagetsi otsika a DC (pansi pa 20V), koma mphamvu zathu za mains wamba ndi AC high voltage (AC 220V).Kuti mutembenuzire mphamvu ya mains kukhala mphamvu yofunikira ndi mikanda ya nyali, timafunikira chipangizo chotchedwa "LED constant current drive power supply".

Mwachidziwitso, malinga ngati magawo a dalaivala akufanana ndi mbale ya nyali, imatha kuyendetsedwa mosalekeza ndikugwiritsidwa ntchito moyenera.Mkati mwa dalaivala ndizovuta.Kulephera kwa chipangizo chilichonse (monga capacitor, rectifier, etc.) kungayambitse kusintha kwa voteji, ndiyeno kuchititsa kuti nyali izime.

Kuwonongeka kwa oyendetsa ndiye vuto lofala kwambiri mu nyali za LED.Nthawi zambiri imatha kuthetsedwa mutasintha dalaivala.

2.Led kuwotchedwa

LED yokha imapangidwa ndi mikanda ya nyali imodzi ndi imodzi.Ngati imodzi kapena gawo lina silinayatsidwa, liyenera kuyimitsa nyali yonseyo.Mikanda ya nyali nthawi zambiri imalumikizidwa motsatizana kenako mofanana - kotero ngati mkanda wanyali wawotchedwa, gulu la mikanda silingayatse.

Pamwamba pa mkanda woyaka moto pali mawanga akuda.Pezani, gwirizanitsani kumbuyo ndi waya ndi dera lalifupi;Kapena mkanda watsopano wa nyali ukhoza kuthetsa vutoli.

Anatsogolera nthawi zina kuwotcha imodzi, zikhoza kukhala mwangozi.Ngati muwotcha pafupipafupi, muyenera kuganizira za vuto lagalimoto - chiwonetsero china cha kulephera kwagalimoto ndikuwotcha mikanda ya nyali.

3. LED kuwala attenuation

Zomwe zimatchedwa kuwonongeka kwa kuwala ndikuti kuwala kwa chowunikira kukucheperachepera - chomwe chikuwonekera kwambiri mu nyali za incandescent ndi fluorescent.

Nyali ya LED siyingapewe kuwonongeka kwa kuwala, koma kuthamanga kwake kowola kumakhala pang'onopang'ono, ndipo nthawi zambiri kumakhala kovuta kuwona kusintha ndi maso.Komabe, sizimatsutsa kuti mbale yotsika kwambiri yotsogolera, kapena yotsika kwambiri, kapena chifukwa cha zolinga monga kutentha kwapang'onopang'ono, kuthamanga kwa kuwala kwa LED kumakhala mofulumira.
