Japanese Patent JP3403736
Kind Code:
B2
Abstract:
A circuit for powering a fluorescent lamp has a direct current power supply (10). An inverter (12) is coupled to the direct current power supply (10) and provides a lamp current to the fluorescent lamp load (14). The inverter(12) is connected to an inverter control circuit (18). A protection circuit (16) for detecting lamp current is coupled to the inverter control circuit (18) such that the inverter control circuit (18) turns off the inverter (12) whenever the protection circuit detects the absence of lamp current.
