Abstract

A circuit for flashing a fluorescent lamp. The circuit includes a first and second terminal for coupling the circuit to a fluorescent lamp circuit. The terminals receive an AC power source. A switching circuit is coupled between the first and second terminals for switching the AC power source. An isolation circuit is coupled to the switching circuit. A control circuit is coupled to the isolation circuit. The control circuit controls the switching circuit in response to an external control signal. The circuit can flash higher power rated lamps or multiple lamps.
