Lighting assembly for multiple fluorescent lamps
First Claim
1. A lighting assembly for use in mounting a plurality of fluorescent lamps comprising:
- a ballast lampholder subassembly located at a first end of the lighting assembly, including a ballast lampholder housing with ballast circuitry mounted within the ballast lampholder housing connected to terminals in lampholders extending from the housing;
at least one lampholder connector mounted on a second end of the lighting assembly, the lampholder connector including spaced-apart lampholders extending from a lampholder connector base with lampholder terminals in at least two of the lampholders being connected by lead wires extending through the lampholder connector base;
wherein the lampholders of the ballast lampholder subassembly and the lampholder connector comprise integrally molded extensions of the ballast lampholder housing and the lampholder connector base, respectively.

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).

11. A ballast lampholder subassembly for use in a fluorescent lighting fixture comprising:
-
a molded ballast lampholder cover with lampholders extending from the ballast lampholder cover, each of the lampholders including a pair of terminal cavities opening to an interior surface of the ballast lampholder cover;
fluorescent lamp terminals insertable into the terminal cavities after first ends of wire leads have been terminated to the fluorescent lamp terminals;
a circuit board with ballast circuitry and ballast components mounted on the circuit board, second ends of the wire leads being attached to the circuit board; and
a ballast lampholder base attached to the ballast lampholder cover to form a ballast lampholder housing, the circuit board and the wire leads which connect the fluorescent lamp terminals to the ballast circuitry and to the ballast components being positioned within the ballast lampholder housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of assembling a ballast subassembly for use in a lighting fixture comprising the steps of:
-
terminating insulated wire leads to terminals;
inserting the terminals into lampholders molded as part of a ballast lampholder housing cover with the insulated wire leads extending from the terminals;
connecting opposite ends of the wire leads to a circuit board containing ballast circuitry and ballast components;
positioning the circuit board between a ballast lampholder housing base and the ballast lampholder housing cover; and
attaching the ballast lampholder housing base to the ballast lampholder housing cover to form a ballast lampholder housing which encloses the circuit board and the wire leads.
