ABSTRACT:
For protection against potentially serious electric shock hazard to a person removing and/or replacing a fluorescent lamp in a fluorescent lighting fixture having an inverter-type electronic ballast, a special protection circuit is provided as part of this ballast.
This protection circuit operates to disable the ballast inverter within about one second after a fluorescent lamp is removed from at least one of its sockets, thereby removing the potentially hazardous voltage present at the fixture's lamp sockets.
