Abstract
A fluorescent lighting assembly (2) includes a ballast lampholder subassembly (4) located at one end of a troffer (80) and at least one lampholder connector (50) located at the opposite end. The ballast lampholder subassembly (4) includes ballast circuitry connected to fluorescent lamp terminals (17) all positioned within a ballast lampholder housing (6). A molded ballast lampholder cover (8) encloses three sides of the ballast lampholder subassembly and a stamped metal plate forms the ballast lampholder base (10), with the ballast circuitry located on a circuit board (27) positioned on the interior surface of the base. Integrally molded lampholders (15) extend from channels (14) on the cover (8) and are positioned between larger enclosure sections (12) which provide space for larger ballast components. Fluorescent lamp terminals (17) are inserted from the interior of the cover into cavities (16) in lampholders (15), and lead wires connect the terminals to the printed circuit board. Lampholder connectors (50) including integrally molded lampholders (51) are located at the opposite end of the fluorescent lighting assembly (2).
