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 ...
Lamp Type Each type of fluorescent lamp has specific electrical require- ments in order to operate at variable light levels and achieve the expected lamp lifetime. Lutron designs each fluorescent dimming ballast to achieve the best performance for each lamp type. The result is superior dimming, ...
Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein specifically to provide a fluorescent light ballast that will dim an unmodified electrodeless lamp across a very wide dimming range....
All electronic ballasts use components with a finite lifetime. A major factor for ballast lifetime is operating temperature. For every 10°C reduction in ballast case temperature, the ballast lifetime is doubled. Lutron dimming ballasts are designed to maximize ballast lifetime by operating at a ...
