How compact fluorescent lamps work–and how to dim them Tom Ribarich, Director, Lighting IC Design Center, International Rectifier Corporation 3/9/2009 7:00 AM EDT Compact fluorescent lamps (CFLs) are replacing incandescent light bulbs at a rapid rate due to their tremendous energy savings and longer lifetime. Additional energy savings can be achieved by dimming, but the electronic ballast required to control the lamp has a higher cost and is difficult to design. This article explains how a CFL works, how to dim them, and describes a solution for 3-way dimming applications. Fluorescence versus incandescence Incandescence is the conversion of heat to light, which requires the filament inside an incandescent lamp to burn at a high temperature (350
