Kodi Dimmer Driver ya LED ndi chiyani?

Popeza ma LED amafunikira magetsi olunjika komanso otsika kuti agwire ntchito, dalaivala wa LED ayenera kusinthidwa kuti aziwongolera kuchuluka kwa magetsi omwe amalowa mu LED.
Dalaivala wa LED ndi gawo lamagetsi lomwe limayang'anira magetsi ndi magetsi kuchokera kumagetsi kuti ma LED azigwira ntchito moyenera komanso moyenera. Dalaivala wa LED amasintha ma alternating current (AC) kuchokera pa mains kupita ku DC (DC) chifukwa magetsi ambiri amayendera pa mains.
Kuwala kwa LED kumatha kuchepetsedwa mwa kusintha dalaivala wa LED, yemwe amayang'anira kuwongolera kuchuluka kwa zomwe zimalowa mu LED. Dalaivala wamtundu wa LED uyu, yemwe nthawi zina amatchedwa woyendetsa dimmer wa LED, amasintha kuwala kwa LED.
Ndikofunikira kuganizira zosavuta za driver wa dimmer ya LED pogula imodzi. Dalaivala wa Dimmer wa LED wokhala ndi phukusi lapawiri-in-line (DIP) amasinthira kutsogolo kumapangitsa kuti zikhale zosavuta kwa ogwiritsa ntchito kusintha zomwe zatuluka, zomwe zimasintha kuwala kwa LED.
Kugwirizana kwa dalaivala wa dimmer ya LED yokhala ndi mbale zapakhoma za Triode for Alternating Current (TRIAC) ndi magetsi ndi chinthu china choyenera kuyang'ana. Izi zimatsimikizira kuti mutha kuyang'anira magetsi othamanga kwambiri omwe akuyenda mu LED komanso kuti dimmer yanu idzagwira ntchito iliyonse yomwe mukuganizira.

Njira ziwiri kapena masinthidwe amagwiritsidwa ntchito ndi madalaivala a dimmer a LED kuti azitha kuyendetsa magetsi omwe amalowa mu LED: kusinthasintha kwa matalikidwe ndi kusinthasintha kwapakati.

Kuchepetsa kuchuluka kwa kutsogolera komwe kumadutsa mu LED ndicho cholinga cha kusintha kwa pulse wide, kapena PWM.
Dalaivala nthawi ndi nthawi amayatsa ndikuyimitsa magetsi ndikuyatsanso kuti ayang'anire kuchuluka kwa magetsi omwe akuyendetsa magetsi a LED, ngakhale kuti magetsi akulowa mu LED amakhalabe osasintha. Chifukwa cha kusinthana kwakanthawi kochepa kumeneku, kuwalako kumacheperachepera ndipo kumalira mofulumira kwambiri moti munthu sangaone.

Kuchepetsa kuchuluka kwa magetsi akulowa mu LED kumadziwika kuti amplitude modulation, kapena AM. Kuwala kocheperako kumabwera chifukwa chogwiritsa ntchito mphamvu zochepa. Momwemonso, kuchepa kwaposachedwa kumabweretsa kutentha kocheperako ndikuwonjezera mphamvu ya LED. Flicker imathetsedwanso ndi njira iyi.
Komabe, kumbukirani kuti kugwiritsa ntchito njira ya dimming iyi kumakhala ndi chiopsezo chosintha mtundu wa LED, makamaka pamilingo yotsika.

Kupeza madalaivala ocheperako a LED kudzakuthandizani kuti mupindule kwambiri ndi kuyatsa kwanu kwa LED. Gwiritsani ntchito mwayi waufulu wosintha makulidwe a kuwala kwa ma LED anu kuti mupulumutse mphamvu ndikukhala ndi zowunikira zabwino kwambiri mnyumba mwanu.
Lumikizanani nafemukufunikira magetsi amtundu wa LED okhala ndi dimmer / dimmer dirver kapena zida zina.
