Future LED dimming tsarin
To wane irin tsarin dimming yakamata LEDs suyi amfani dashi?
4.1 PWM Dimming
Kamar yadda aka ambata a baya, Dimming LED shine mafi kyawun amfani da dimming PWM. Lokacin amfani da PWM dimming, zaka iya shigar da janareta mai sauƙi na PWM a cikin bangon bango, sannan yi amfani da potentiometer don sarrafa rabon aikin PWM don cimma dimming. Amma idan kuna son kunnawa da kashe fitilu, kuna buƙatar ƙara wayoyi biyu. Sabili da haka, bai dace da gubar na canza thyristor a bangon asali ba. Maɓalli na asali na thyristor yana da jagora guda biyu kawai, waɗanda za'a iya dimm kuma a canza su. Wannan fa'idar yana da wahala a daidaita. Koyaya, a zahiri, fitilun da aka fi amfani da su na dimming sune fitilun tebur ko fitulun tsaye. Ana shigar da waɗancan na'urori masu kashe wuta akan igiyar wuta maimakon bango, don haka ba kome ba ne a yi amfani da jagororin biyu a bango. A wasu kalmomi, ana iya yin amfani da dimming PWM kai tsaye zuwa ga fitilun tebur masu dimming.
