A lamp dimmer suited for fluorescent and any other type of lights and/or lamps which controllably notches the alternative voltage cycle depending on the cycle programmed by the microcontroller. As the zero crossing point is sensed by solid state circuitry, one microcontroller senses the information and relays it to another microcontroller which has a progressive and non-interruptive control over the switching of the optocoupler. The notches are programmed with starting and ending points which can selectively notch the AC cycle in any position, giving the ultimate control over the amount of power delivered to the lamp. This type of control can be used to ultimately slice the timing of the North American 60Hz AC power cycle into steps within the millisecond region. A infrared detector is used to sense the signals from any available infrared module which controls the timing delivered by the microcontroller. The sensor has a wide range of light spectrum giving access by any commercially available module control of this lamp dimmer. The sensor is separate from the control box, giving simple access to dimming functions by simple installation. Also, available is a stationary control for non-remote control.
