Dimmer switch with gradual reduction in light intensity

摘要: A time-delayed, variable light intensity control is configured to operate in a conventional mode which the illumination level of incandescent lights adjusted accordance with rotation dimmer knob and automatic dimming modes further dimmed over predetermined period time, either low suitable for use as night light, or until extinguished. The controls levels well time delay during by varying phase angle at power triac triggered. controlled timing generation first pulse fixed occurs one half cycle later. system useful other AC systems.
