kodi dimmable led driver imagwira ntchito bwanji?

Dalaivala wocheperako ndi chipangizo chomwe chimagwiritsidwa ntchito kusintha kuwala kapena kulimba kwa zowunikira zowunikira zowunikira (LED). Imasintha mphamvu zamagetsi zomwe zimaperekedwa ku ma LED, zomwe zimalola makasitomala kusintha kuwala kowala momwe akufunira. Madalaivala ocheperako nthawi zambiri amagwiritsidwa ntchito kupanga zowunikira mosiyanasiyana m'nyumba, maofesi, ndi zina zamkati ndi zina.kuyatsa panjamapulogalamu.

Madalaivala ocheperako a LED amagwiritsa ntchito Pulse Width Modulation (PWM) kapena Analog Dimming. Nayi tsatanetsatane wa momwe njira iliyonse imagwirira ntchito:

PWM: Munjira iyi, dalaivala wa LED amasintha mwachangu ma LED apano ndikuzimitsa pafupipafupi kwambiri. Microprocessor kapena digito yozungulira imawongolera kusintha. Kuti mupeze mulingo woyenera wowala, ntchito yozungulira, yomwe imawonetsa kuchuluka kwa nthawi yomwe LED ili kuyatsa motsutsana ndi kuzimitsa, imasinthidwa. Kuzungulira kwapamwamba kumatulutsa kuwala kochulukirapo, pomwe kucheperako kumachepetsa kuwala. Kusintha kwafupipafupi kumakhala kofulumira kotero kuti diso la munthu limawona kuwala kosalekeza ngakhale kuti LED imayatsa ndikuzimitsa nthawi zonse.

Njirayi, yomwe nthawi zambiri imagwiritsidwa ntchito m'makina a digito, imapereka chiwongolero chenicheni pakutulutsa kuwala.

Dimming ya Analog: Kuti musinthe kuwala, kuchuluka kwa zomwe zikuyenda kudzera mu ma LED zimasinthidwa. Izi zimatheka mwa kusintha mphamvu yamagetsi yomwe imagwiritsidwa ntchito kwa dalaivala kapena poyendetsa panopa ndi potentiometer. Dimming ya analogi imatulutsa kuwala kosalala koma imakhala ndi dimming yotsika kuposa PWM. Zimapezeka kawirikawiri m'makina akale a dimming ndi ma retrofits pomwe kugwirizana kwa dimming kumakhala vuto.

Njira ziwirizi zitha kuwongoleredwa ndi ma protocol osiyanasiyana a dimming, kuphatikiza 0-10V, DALI, DMX, ndi zosankha zopanda zingwe monga Zigbee kapena Wi-Fi. Ma protocol awa amalumikizana ndi dalaivala kuti atumize chizindikiro chowongolera chomwe chimasintha kulimba kwa dimming poyankha zomwe wogwiritsa ntchito alowetsa.

Ndikofunika kukumbukira kuti madalaivala ocheperako a LED ayenera kugwirizana ndi dimming system yomwe ikugwiritsidwa ntchito, ndipo kugwirizana kwa dalaivala ndi dimmer kuyenera kutsimikiziridwa kuti zigwire bwino ntchito.

Lumikizanani nafendipo titha kugawana zambiri za magetsi amtundu wa LED.
