The reflecting plate leading end 4c is bent toward the arrangement side of the fluorescent lamp 1 on the leading end side of the portion 4b, and the reflecting plate upright portion 4b and the upright portion 3b of the lamp holder fixture 3 are flush with each other. Further, the reflection plate bottom 4a and the mounting portion 3a which is the bottom of the lamp holder fixture 3 are configured to be accommodated in different planes.

In order to assemble the respective components thus configured, first, the lead wire 1a of the fluorescent lamp 1 is inserted into the lead wire insertion hole 2a of the lamp holder 2, and the tube end portion 1b of the fluorescent lamp 1 is inserted. Is inserted into the lamp holder 2b and held therein. Subsequently, the lamp holder 2 is inserted into and held by the substantially U-shaped holding portion 3c of the lamp holder fixture 3 integrally formed at both ends of the reflector plate 4, and the reflector plate 4 is mounted on the printed circuit board 5. It is placed and screwed to the printed circuit board 5 with the screw hole 3d of the mounting portion 3a. Then, the lead wire 1a is bent toward the printed circuit board 5 side and inserted into the hole 5a of the printed circuit board 5, and the tip of the lead wire 1a is soldered to the copper foil of the printed circuit board 5.

With such a configuration, in the lighting fixture of the present invention, the number of parts is reduced, the workability of assembly is improved, and the lamp holder 2 and the lamp holder fixture 3 are integrally formed. Since it is directly fixed to the reflector plate 4 that is fixed, the positional relationship between the central axis of the fluorescent lamp 1 and the reflector plate 4 does not vary due to the assembly of the lighting fixture, and is always kept constant. There is no variation in characteristics.

FIG. 2 shows a second embodiment of the present invention. In the first embodiment, a narrow protruding piece bent toward the printed circuit board 5 in the vicinity of both ends of the reflection plate 4 is provided. 4d is provided, and instead of the screw in the first embodiment, this protruding piece 4d is inserted into the mounting hole 5d of the non-charged component provided on the printed circuit board 5 and the tip thereof is bent. The reflector 4 and the lamp holder fixture 3 formed integrally with the reflector 4 are attached. Even with this structure, the same effects as those of the first embodiment can be obtained, and since screws are not used, the workability of assembly is further improved.

In the second embodiment, an example in which the flat plate-shaped mounting portion 3a is provided at the end of the reflection plate 4 is shown, but the present invention is not limited to this, and the mounting portion 3a is not provided. May be

Further, in each of the above-described embodiments, the reflection plate upright portion 4b and the upright portion 3b of the lamp holder fixture 3 are in the same plane, and the reflection plate bottom portion 4a and the bottom portion of the lamp holder fixture 3 are located in the same plane. The description has been given by taking the example in which the certain mounting portion 3a is configured so as to be housed in another same plane, but the present invention is not limited to this, and the reflector standing portion and the lamp holder fixing portion standing portion. Are not on the same plane and the upright part of the lamp holder fixture is closer to the fluorescent lamp installation side than the reflector upright part, or the upright part is bent in the middle and the lamp holder fixture holding part However, it goes without saying that it may be provided so as to project from the upright portion to the side where the fluorescent lamp is disposed to secure the distance between the fluorescent lamp and the reflector.
