BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention will be described based on matters unique to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

In the illustrated embodiment, a lighting circuit board 3 on which required components 2 are mounted is provided in a main body case 1 in a horizontal direction, and lead wires 4 drawn out from the lower surface of the lighting circuit board 3 are provided.
This is a lighting fixture in which a plurality of sockets 6 and 7 are provided through a socket 5 and annular fluorescent lamps 8 and 9 are attached to the sockets 6 and 7 respectively. The main body case 1 includes the sockets 6 and 7 described above.
And a pair of case bodies 1a, 1 formed in a lateral direction and including a plurality of side arms 10, 11 which are respectively housed in the lead wires 4, 5 and which are formed vertically and inward and outward.
b. The lead wires 4 and 5 have a plurality of lead wires 4 and 5 having substantially the same length for each of the sockets 6 and 7.
And the lead wires 4 and 5 of each of the sets 12 and 13 are connected to the lighting circuit board 3 with respect to the inner socket 6.
From the inside of the lighting circuit board 3 to the outside socket 7, and is connected to the lighting circuit board 3 in a line substantially perpendicular to the drawing direction from the lighting circuit board 3. Have been. Note that there are four lead wires 4, 5 each, and all the lead wires 4 have substantially the same length and all the lead wires 5 have substantially the same length. However, the lead wire 5 is formed longer than the lead wire 4. You.

More specifically, a pair of case bodies 1a and 1b constituting the main body case 1 are formed of, for example, a synthetic resin, and are connected to each other by screws (not shown) to form an outer shell of the main body of the lighting fixture. I have. A metal plate 15 to which a switch 14 is attached is fixed in the main body case 1 by appropriate means, and a lower end of a suspension cord 16 introduced from an upper end of the main body case 1 is connected to an upper surface of the switch 14 by a connector. Various components constituting the high-frequency inverter are mounted on the lighting circuit board 3 fixed by appropriate means in the main body case 1 as shown in FIG. 3, but the components other than the electrolytic capacitor 2 are omitted in FIG. I have. In addition,
Most of the pair of case bodies 1a and 1b are in contact with each other so as to have seams 17;
In the center of the bottom surface of the lighting circuit board 3, there is formed a gap 18 which is formed in a substantially elliptical shape. The metal forming plate 19 exposed from the gap 18 functions as a reflecting plate of the fluorescent lamps 8 and 9.

The AC power received by the cord 16 is supplied to the lighting circuit board 3 via the switch 14, and the output of the lighting circuit board 3 is supplied to the fluorescent lamps 8 and 9 via the leads 4 and 5 and the sockets 6 and 7. Supplied respectively. In the main body case 1, a support spring 21 is fixed to the side arm 20 opposite to the side arms 10 and 11, and the fluorescent lamps 8 and 9 are supported by the support spring 21 and the sockets 6 and 7, respectively. Have been. The metal forming plate 19 is formed with holes 24 and 25 through which a drawstring 22 connected to the switch 14 and a bead ball 23 mounted on the side of the switch 14 pass.

According to this embodiment, a pair of case bodies 1 is provided.
a and 1b are combined and assembled into the main body case 1 so that each set 12, 13 of a plurality of lead wires can be easily accommodated in a pair of case bodies 1a, 1b including a plurality of side arms 10, 11, respectively. There is. That is, the lead wires 4 and 5 consist of a plurality of sets of lead wires 12 and 13 having substantially the same length for each of the sockets 6 and 7, and the lead wires of each set 12 and 13 correspond to the inner socket 6. In addition, the lighting circuit board 3 is pulled out from the inside of the lighting circuit board 3 to the outer socket 7 from the inside of the lighting circuit board 3, and is aligned in a direction substantially perpendicular to the drawing direction from the lighting circuit board 3. Since the connection is made to the lighting circuit board 3, the occupation width of the lead wires 4, 5,... Of each set 12, 13 does not become wide when viewed in FIG. 1
Since the wires 4... 5 can be prevented from being entangled or caught in the pair of case bodies 1 a and 1 b including the wires 0 and 11, the side arms 10 of the wires 4.
11 can be easily stored, and assembling workability is improved.
