can I use a pulse width modulated signal to control the brightness of a halogen lamp?
can anyone tell me a bit about halogen lamps why are they used are they more efficient than incandecent ?
I have a slide projector and i want to control the brightness of the lamp.
oh its run on AC so does that mean I can use a simple triac circuit ? I think I need a 1 KHz signal though so that the fliker is not visible so I would need the PWM generator wouldn't I ?
