ABSTRACT:
A dimmer logic for fluorescent lamps is described which operates after the principal of a two-point circuit with two stable operating points, where in dimmer operation periodic changes between the two operating points takes place. By periodically switching on and off the fluorescent lamp the average brightness of the fluorescent lamp is reduced. The dimmer logic can be extended by sensor inputs for current and voltage to control the voltage, current and power. By appropriate design of the dimmer logic a control and protection circuit for overcurrent, overvoltage and overpower can be realized.
