摘要:
A transformer wiring method and apparatus for fluorescent lighting are described. The fluorescent lighting apparatus includes a transformer and a ballast. An installer is easily able to balance the system load because each fluorescent lighting apparatus includes its own transformer and may be connected directly to a facility's three phase power distribution while still operating at rated voltages. Moreover, the ballast is protected from surges and stray voltages thereby reducing the frequency of ballast failures.

A light fixture includes a raceway, a lampholder, and a power pack. The raceway includes an aperture and a locking aperture. The lampholder is electrically connected to a lampholder connector. The power pack includes a power pack cover and a ballast. The power pack cover includes a latching end. The ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to the lampholder connector. The latching end includes a flange adapted to mate with the aperture of the raceway and a locking protrusion adapted to mate with the locking aperture of the raceway such that the power pack is detachably mountable to the raceway.

A light fixture includes a lampholder mounted to a raceway, where the lampholder is electrically connected to a lampholder connector. A power pack includes a power pack cover and a ballast. An outer surface of the power pack cover includes an emissive coating such that heat generated by the ballast is emitted from the power pack cover. The ballast is mounted in direct contact with the power pack cover such that the heat generated by the ballast is conducted from the ballast to the power pack cover. The ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to the lampholder connector.

A light fixture includes a first raceway disposed at a first end of the light fixture, a second raceway disposed at a second end of the light fixture, and a detachable cover that is removably coupled to the first raceway and to the second raceway. A ballast and power input wiring is coupled to the detachable cover, and an elongated lamp electrically coupled to the ballast. The light fixture also includes a power input connector having a socket portion and a plug portion, one of the socket portion and the plug portion coupled to the detachable cover and electrically connected to the power input wiring, and the other of the socket portion and the plug portion connectible to a power supply line to provide electrical power to the light fixture from a power source.

A system for supporting and leveling a light fixture having a fixture body supporting one or more light sources, and connectors on the fixture body, and a pair of V-shaped hanger rods, where each hanger rod has an apex area and first and second ends, and the first and second ends are each configured to be coupled to one of the connectors. A pair of suspension rods are each configured to engage an overhead structure. A pair of spring clip brackets each having a slot and an aperture are releasably and adjustably secured along the length of one of the suspension rods, and also have a receptacle with a locking tab that receives and retains the apex area of one of the hanger rods.
