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.
