Abstract

PROBLEM TO BE SOLVED: To facilitate the assembling, the mounting on a chassis and the integration into a luminaire, and shorten the whole length by arranging a mounting claw to be engaged with a chassis and a lamp terminal for fluorescent lamp in prescribed positions. SOLUTION: Lamp terminals for 32W and 40W are juxtaposed on one edge of a conductive plate 4, and a lamp terminal for 30W is provided in the edge crossing one end part on the other end part of the plate 4. Lead wires 26, 27 for 32W and 40W fluorescent lamps are thus delivered in the same direction from one terminal part of a composite wiring block 1, and a lead wire 28 for 30W fluorescent lamp is delivered in the direction crossing the wires 26, 27 from the other end part of the block 1. Lamp sockets 29, 30, 31 for 32W, 40W, 30W are installed to the tips of the wires 26, 27, 28, respectively. Since each lead wire and each lamp socket are never collected to a narrow section, the assembling work is facilitated, and the whole length can be shortened. The installation can be also facilitated by providing mounting claws 11, 12 on a cover 3.
