Dimming control techniques using self-excited gate circuits |
摘要 |
There is described methods and techniques for providing dimming control of low-cost fluorescent lamps that are driven by self-excited gate circuits and which are nominally non-dimmable. A dimming function is achieved by providing a variable DC voltage input to the ballast. It is possible to retroactively change existing non-dimmable lamps into dimmable lamps, or to form new low-cost dimmable fluorescent lamps.
