Zifukwa kuwonongeka kwa LED khoma makina ochapira
Washer khoma la LED ndi nyali yotsika kwambiri yamagetsi, yomwe imakhudzidwa kwambiri ndi magetsi. Choncho, kuwala kwa LED yonse nthawi zambiri kumayang'aniridwa ndi zamakono, ndipo mtengo wamtengo wapatali wa ntchito yonseyi ndi 20 mA. Ngati chapano chikupitilira mtengo wapamwambawu, zitha kupangitsa kuti chowotchera khoma la LED chiwonongeke mosavuta.
Kutengera mfundo iyi, zifukwa zowonongera mawotchi a LED m'moyo weniweni nthawi zambiri zimakhala ndi izi:
Choyamba: chosalowa madzi. Pamene nyali za LED zimagwiritsa ntchito zipangizo zosiyana siyana zopanda madzi, mphamvu ya ntchito yopanda madzi ndi kutalika kwa moyo wa ntchito yopanda madzi ndi yosiyana. Pambuyo pazida zina zopanda madzi za LED zikakalamba ndikutha, madzi amalowa ndikupangitsa kuti dera likhale lalifupi.
Chachiwiri: Dalaivala kapena mkanda wa nyali wawonongeka. Kunena zoona, mu nyali za LED, dalaivala ndi mikanda ya nyali ndizosavuta kuthyoka. Chifukwa voteji yogwira ntchito ya nyali za LED nthawi zambiri imakhala 24V, ndipo voteji yamagetsi osinthika ndi 220V, nthawi zambiri pamafunika kudutsa dalaivala kuti apange ma voliyumu osinthika komanso njira yokhazikika yapano. Kusankha kwa magalimoto pamsika kulinso kosiyanasiyana, ndi madola angapo pazoyipa ndi madola ambiri pazabwino. Choncho, nthawi ya moyo wa galimotoyo imasiyanasiyana malinga ndi khalidwe. Pamene dalaivala sagwira ntchito bwino, imayambitsanso mphamvu zamagetsi ndi zamakono, zomwe pamapeto pake zidzachititsa kuti chiwonongeko chonse chiwonongeke. Mikanda ya nyali imagwiritsidwa ntchito ndi opanga akuluakulu, ndipo moyo wawo wabwinobwino nthawi zambiri umakhala wapamwamba. Komabe, mikanda ya nyali imakhudzidwa ndi chilengedwe (kutentha kwakukulu). Choncho, n'zosavuta kusweka.
Chachitatu: kugwirizanitsa zigawo. Apa ndi pamene capacitance ndi kukaniza sizikugwirizana panthawi yowerengera, pambuyo pa nthawi inayake yogwiritsira ntchito, mphamvu yosadziwika bwino idzachitika, yomwe idzawotcha dera lonselo.
Zomwe zili pamwambazi ndizo zifukwa zambiri zowonongeka kwa makina ochapira panja. Pakhoza kukhala zifukwa zina, koma ndizosowa.
