TRIAC Dimming vs PWM Dimming
PWM yana nufin “Haɓaka Faɗin bugun bugun jini”. Ba kamar analog TRIAM dimming ba, PWM yana da fasahar dimming dijital. Wannan hanya ce mai inganci don sarrafa da'irori na analog waɗanda ke amfani da fitowar dijital na microprocessor. Auna ƙarfin siginar analog kuma yana da sauƙi tare da daidaita bugun bugun jini (PWM). Kuna iya sarrafa zagayowar aiki na raƙuman murabba'in ta amfani da ƙididdiga masu ƙima.
Siginar PWM ya kasance na dijital koda lokacin da cikakken sikelin DC ba ya kasancewa koyaushe. Lokacin da aka haɗa hasken zuwa wadatar DC, yana kunna. Bugu da ƙari, lokacin da babu wutar lantarki ta DC, wutar lantarki ta katse, hasken ya daina karɓar siginar, kuma yana kashewa.
Ana amfani da PWM a fannoni da yawa; misali- ana amfani da shi wajen aunawa, sadarwa, sarrafa wutar lantarki da juyawa, da hasken LED. Ya fi sauƙi don amfani kuma yana dacewa da yawancin hasken wuta. Wato saboda yawancin masu sarrafa microcontrollers na zamani da DSPs suna da masu kula da PWM da aka gina kai tsaye a cikin guntu. Wannan yana sa ikon dijital ya fi dacewa gabaɗaya zuwa TRIAC dimming, wanda bai dace da duk LEDs ba. Bayan haka, zaku iya yanke farashin makamashi ta hanyar canza dimmer TRIAC analog zuwa dijital PWM dimmer.

TRIAC Dimming vs DALI Dimming
DALI ba daidai ba hanya ce mai dusashewa amma fasaha ce mai sarrafa haske ta dijital bisa ka'idar DALI.
