Kodi Dalaivala wa Dimmer wa LED ndi chiyani? Njira Ziwiri Zochepetsera Kuchuluka kwa Kulemera Zomwe Muyenera Kudziwa

Kuwala kwa LED (light-emitting diode) kumasinthasintha kwambiri. Koma chifukwa ma LED amagwira ntchito pa mphamvu yamagetsi, kufinya kwa LED kungafunike kugwiritsa ntchito Madalaivala a LED dimmer, zomwe zingagwire ntchito m'njira ziwiri.

Kodi Dalaivala wa LED Dimmer ndi chiyani?

Popeza ma LED amayenda ndi magetsi otsika komanso mphamvu yamagetsi yolunjika, munthu ayenera kuwongolera kuchuluka kwa magetsi omwe amalowa mu LED mwa kusintha LED.'dalaivala.

Mzere wa LED wamagetsi otsika komanso okwera kwambiri umafuna chowongolera cha LED choyezera kuwala, chomwe chimadziwika kwambiri pa nsanja yamagetsi yamagetsi ndipo chikuphatikizapo mizere ya LED, chowongolera cha LED choyezera kuwala ndi chowongolera kuwala, zina zimakhala ndi zolumikizira. Chifukwa chake pa mzere wa LED woyezera kuwala, ndikofunikira.

Popeza dalaivala wa LED ndiye amene ali ndi udindo wowongolera magetsi omwe amalowa mu LED, ndi kusintha chipangizochi komwe LED imatha kuzimitsidwa. Dalaivala wa LED wosinthidwayu, yemwe amadziwikanso kuti dalaivala wa LED dimmer, amasintha kuwala kwa LED.

Mukagula chowongolera chabwino cha LED dimmer, chimatha kusinthidwa.'Ndikofunika kusamala ndi momwe imagwiritsidwira ntchito mosavuta. Kukhala ndi chowongolera cha LED dimmer chokhala ndi ma switch awiri a in-line package (DIP) kutsogolo kumathandiza ogwiritsa ntchito kusintha mosavuta mphamvu yotulutsa, motero, kusintha kuwala kwa LED.

Sikuti ndi mzere wa LED wokha womwe umawala, komanso wa RGB RGBW strips, tili ndi pixel driver. Controller ndi yofunika kwambiri, traic, daynamic pixel ndi CCT. Makasitomala amakonda yaying'ono komanso yogwira ntchito zambiri, o, musaiwale DMX control. Malo otchuka kwambiri ndi KTV, kilabu ndi ntchito yowunikira panja, Inde, ndikwabwino kusintha mlengalenga kunyumba.

Chinthu china choyenera kuyang'anitsitsa ndi kugwirizana kwa dalaivala wa LED dimmer ndi ma Triode for Alternating Current (TRIAC) makoma ndi magetsi. Izi zimatsimikizira kuti mutha kuwongolera kuchuluka kwa magetsi omwe amalowa mu LED mwachangu kwambiri, ndipo dimmer yanu idzagwira ntchito iliyonse yomwe mukufuna.

Kusinthasintha kwa pulse width modulation (PWM) kumaphatikizapo kufupikitsa kuchuluka kwa mphamvu yotsogola yomwe imadutsa mu LED.

Mphamvu yamagetsi yomwe imalowa mu LED ndi yomweyo, koma dalaivala nthawi zonse amayatsa ndi kuzimitsa ndikuyatsanso mphamvu yamagetsi kuti azitha kuyendetsa mphamvu yamagetsi yomwe imagwiritsa ntchito LED. Kusinthana kwachangu kumeneku kumapangitsa kuti magetsi azizimitsa, ndipo kuwala kwake kumawoneka mwachangu kwambiri moti diso la munthu silingathe kugwira.

Kusinthasintha kwa ma amplitude (AM) kumaphatikizapo kuchepetsa mphamvu yamagetsi yomwe imalowa mu LED. Ndi mphamvu yochepa kumabweretsa kuwala kofooka. Mofananamo, ndi mphamvu yochepa kumabweretsa kutentha kochepa komanso kugwira ntchito bwino kwa LED. Njirayi imachotsanso chiopsezo cha kuzima.

Komabe, dziwani kuti njira iyi yochepetsera kuwala imaika pachiwopsezo kusintha mtundu wa LED, makamaka pamlingo wotsika. 

Kuti mudziwe zambiri za momwe njira zathu zowunikira ndi kuziziritsa magetsi zingathandizire polojekiti yanu kupambana, chonde titumizireni uthenga wokhudza mzere woziziritsa magetsi wokhala ndi dalaivala kapena zina zomwe mukufuna!
