Abstract
A fluorescent lighting assembly includes an electrically conductive lighting fixture (10) having an electrical socket bar (20), a wireless ballast (30) having lamp circuitry, and lamp receiving sockets (28) mounted thereon. The assembly is adapted for lighting one or more fluorescent lamps (14). In operation, current driven through each fluorescent lamp is returned to the ballast via the fixture. The assembly includes ballast safety circuitry for preventing both electrical shock upon contact with the assembly and risk of fire due to a poor electrical joint within the lamp circuitry.
Claims8
A lighting fixture assembly, comprising:
- a troffer having an electrically conductive surface;
- first and second electrical sockets mounted on the electrically conductive surface of said troffer and positioned for supporting a fluorescent lamp therebetween,
- an electronic ballast mounted on the electrically conductive surface of said troffer and including lamp ballasting circuitry, said lamp ballasting circuitry electrically connected to the first pair of lamp pins via the first electrical socket and electrically grounded to the conductive troffer surface,
- the second pair of lamp pins electrically connected to the conductive surface of the troffer via said second electrical socket,
- said troffer providing an electrically conductive path back to said lamp ballasting circuitry.
