Abstract
The proposed dimming method for fluorescent lamps consists of a wall unit and a light unit connected by two wires only. The rheostat of a triac dimmer restricts the cut-in angle to a small amount to be detected by the ballast controller. The angular information is then converted to frequency information in driving the lamp with desirable intensity
