Kodi Dimmer Driver ya LED ndi chiyani? Njira ziwiri za Dimming zomwe muyenera kudziwa

Kuwala kotulutsa diode (LED) ndikosavuta kusintha. Koma chifukwa ma LED amagwira ntchito pakali pano, kufinya kwa LED kungafune kugwiritsa ntchito Ma driver a dimmer a LED, yomwe ingagwire ntchito m'njira ziwiri.

Kodi Dimmer Driver ya LED ndi chiyani?

Chifukwa ma LED amayenda pamagetsi otsika komanso mwachindunji, munthu ayenera kuyang'anira kuchuluka kwa magetsi omwe amalowa mu LED posintha mawonekedwe a LED.'s driver.

Ma voliyumu otsika komanso okwera kwambiri a LED amafunikira dalaivala wa dimmer ya LED, yotchuka kwambiri papulatifomu yazamagetsi yamagetsi imaphatikizapo mizere ya LED, dalaivala wa LED ndi wowongolera, ena azikhala ndi zolumikizira.

Chifukwa dalaivala wa LED ndi amene ali ndi udindo woyang'anira magetsi omwe amalowa mu LED, ndikusintha chipangizochi kuti LED iwonongeke. Dalaivala wosinthidwa wa LED, yemwe amadziwikanso kuti woyendetsa dimmer wa LED, amasintha kuwala kwa LED.

Mukakhala pamsika woyendetsa bwino wa LED dimmer, izo's zofunika kulabadira ake omasuka ntchito. Kukhala ndi dalaivala wa dimmer wa LED wokhala ndi masiwichi apawiri-in-line (DIP) kutsogolo kumathandizira ogwiritsa ntchito kusintha mosavuta zomwe atulutsa, chifukwa chake, kusintha kuwala kwa LED.

Osati kokha kwa dimming led strip, komanso RGB RGBW n'kupanga, tili ndi pixel driver.Controller ndiyofunikanso, traic,daynamic pixel ndi CCT.Customer ngati iyo yaying'ono komanso yogwira ntchito zambiri, o, musaiwale za DMX contro also.The most popular scene ndi KTV, kalabu ndi ntchito yowunikira Panja, Ndithu, ndikwabwinonso kusintha mlengalenga kunyumba.

Chinanso chomwe muyenera kuyang'ana ndikuphatikizana kwa dalaivala wa dimmer wa LED wokhala ndi mbale zapakhoma za Triode for Alternating Current (TRIAC) ndi zida zamagetsi. Izi zimatsimikizira kuti mutha kuwongolera kuchuluka kwa magetsi omwe akuyenda mu LED mwachangu kwambiri, ndipo dimmer yanu idzagwira ntchito iliyonse yomwe muli nayo.

Pulse wide modulation (PWM) imaphatikizapo kufupikitsa kuchuluka kwa zomwe zikuyenda kudzera pa LED.

Zomwe zikuyenda mu LED ndizofanana, koma dalaivala nthawi zonse amatsegula ndikuyimitsa magetsi kuti athetse kuchuluka kwa magetsi a LED. Kusinthana kwachangu kumeneku kumapangitsa kuyatsa kocheperako, komwe kumakhala kuthwanima kosawoneka bwino kwambiri kuti maso a munthu azitha kugwira.

Amplitude modulation (AM) imaphatikizapo kuchepetsa mphamvu yamagetsi yomwe ikuyenda mu LED. Ndi mphamvu zochepa pamabwera kuwala kocheperako. Momwemonso, ndi kutsika kwapano kumabwera kutentha kochepa komanso mphamvu yapamwamba ya LED. Njira imeneyi imathetsanso chiopsezo cha flicker.

Dziwani, komabe, njira yochepetsera iyi imakhala pachiwopsezo chosintha mtundu wa LED, makamaka pamilingo yotsika. 

Kuti mudziwe zambiri za momwe kuyatsa ndi kuyatsa kwathu kungathandizire projekiti yanu kuchita bwino, chonde titumizireni kuti mupeze mawu amtundu wa dimming ndi dalaivala kapena zambiri zomwe mukufuna!
