A dimmable ballast and methods are presented in which the operating frequency of a self-oscillating inverter is controlled according to a sensed lamp current for dimming control or cathode heating, and an AC bus voltage of the inverter is controlled to be at or below a voltage threshold value ...
This gas excites the phosphor lighting element inside, producing visible light regulated by the ballast. CFL This energy-efficient, curved-tube lightbulb is another form of fluorescent lighting, and was designed to replace incandescent bulbs in lamps or fixtures....
