An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

The lighting fixture assembled as shown in FIGS. 2 and 3 includes a fixture body 11, a pair of socket fittings 12, a pair of lamp sockets 13, a fluorescent lamp 14,
It is configured to include a reflecting plate 15, a cover 16, a lighting component 17, a pair of side plates 26, and the like.

The device main body 11 is formed by bending a sheet metal by press forming, and has one side 18 and the other side 19 that are connected to each other at substantially right angles, as shown in FIGS. 1 and 2. In the case of this embodiment, the one side 18 is along the horizontal direction 1ζ so as to face the lower surface of the shelf. The leading edge 18a of one side 18 is bent downward in the figure. moreover,
As shown in FIG. 2, a lighting component 17 such as a ballast is fixed to the inner surface of one side 18. Further, the tip edge I9a of the other side 19, which runs in the vertical direction in the figure, is bent forward in the figure.

For mounting a pair of sockets, the metal fittings 12 are stronger than the metal plate of the main body 11 and are L-shaped, and their width in the direction perpendicular to the length of the side 18 is longer than that of the person. (shown as dimension B in Figure 1). These metal fittings 12 have their cover plate portions 12a overlapped with the outer surfaces of both lengthwise ends of the one side 18, and are respectively attached over substantially the entirety of these both ends. Due to the above-mentioned dimensional relationship (A<B), the front half of the socket mounting fitting 12 protrudes forward of the above-mentioned side 18. The metal fitting 12 and one side 18 are connected by a fixing device 20 such as a set screw shown in FIG. 1, but it may also be done by welding, claw engagement, or the like.

A lamp socket 13 is attached to the front portion of a socket mounting plate portion 12b which extends approximately perpendicularly to the cover plate portion 12a of the metal fitting 12. This attachment is performed using a fixing device 21 such as a screw inserted in the direction of the arrow in FIG.

A pair of lamp sockets 13 are provided facing each other, and a rod-shaped fluorescent lamp 14 is removably supported between them.

The reflector plate 15 is obtained by press-forming a sheet metal.
It has a main body cover part 15a and a reflecting part 15b.

A hook step 22 is formed on the main body cover part 15a over the entire length direction.

Further, a hook groove 23 having a V-shaped cross section is formed on the tip edge of the reflective portion 15b, and recesses 24 into which the sockets 13 are inserted are provided at both longitudinal ends of the reflective portion 15b. There is.

This reflecting plate 15 is provided to cover the inner surface of the instrument main body 11, as shown in FIG. That is, this reflective plate 15
is positioned by abutting the part of the main body cover part 15a connected to the reflecting part 15b with the tip edge 18a, and in this state, both lengthwise ends of the reflecting part 15b are fixed with fixing tools 25 such as screws, and the above-mentioned installation is carried out. It is fixed to the front protruding portion of the cover plate portion 12a of the metal fitting 12. Thereby,
The main body cover portion 15a is disposed to cover the inner surface of the instrument main body 11, and the reflective portion 15b is disposed between the pair of socket fittings 12 and the forward protruding portion thereof.

The cover 16 is made of transparent synthetic resin or the like. One of the longitudinal edges of the cover 16 is an engaging edge 16a, and the other is a hook bent into a V-shaped cross section as an edge 16b. This cover 16 utilizes its elasticity to hook the engagement edge 16a to the stepped portion 22, and to hook the engagement edge 16a to the edge 16b.
By hooking the lamp 14 into the groove 23, the lamp 14 is covered with the reflector plate 15 and the lamp 14 is held in place.

The side plate 26 is a molded product of synthetic resin or metal,
It has a cap shape with an annular peripheral wall around the periphery. These side plates 26 are connected to the other side 19 of the instrument main body 11 and the reflector plate 15.
The respective lengthwise ends of the cover 16 and the socket mounting are fitted to the outer periphery of the instrument end formed by the metal fitting 12 so as to be housed inside. It is stopping the movement of.

To assemble the lighting fixture with the above configuration, first, the socket mounting with the lamp socket 13 fixed is carried out by placing the metal fittings 12 over both longitudinal ends of the fixture body 11 with the lighting parts 17 fixed to the inner surface of the fixture. Each is fixed at 20. Next, the reflector plate 15 is fixed to the socket fitting 12 with a fixture 25, and the inner surface of the instrument body 11 is covered with the instrument cover portion 15a of the reflector plate 15. When installing the reflector 15, the lamp socket 13 is sometimes exposed through the recess 24. Thereafter, the fluorescent lamp 14 is supported between the opposing lamp sockets 13, and then a cover 16 covering the lamp 14 is hooked onto the reflector plate 15 and held. Note that the procedure is as described above. Finally, the side plate 26 is fitted onto the outer periphery of the end of the instrument formed by the other side 19 of the instrument main body 11, the longitudinal ends of the reflector 15, the cover 16, and the socket fitting 12. The above procedure completes the assembly of the lighting fixture shown in FIGS. 1 and 2.

The final step in the above assembly can be easily performed for the following reason. That is, according to the above configuration,
When installing a lamp socket, the metal fitting 12 is attached to one side 1 of the fixture body 11.
8, and is attached to both end portions in the length direction so as to cover substantially the entire length thereof. In other words, even if the end of one side 18 of the instrument main body 11 is deformed in a wavy manner, the deformation overlaps the outer surface of the end of the one side 18. It can be covered up.

When the side plate 26 is pushed into and fitted into the end of the appliance, the annular peripheral wall of the side plate 26 is fitted into the end of the appliance using the cover plate 12a of the metal fitting 12 as a guide for mounting the lamp socket. Ru.

Therefore, even if the end of one side 18 of the device main body 11 is deformed in a wavy manner, this deformation will not adversely affect the fitting operation of the side plate 26, and therefore the side plate 26 will not be damaged. 26 fitting operations can be easily carried out. Note that the above effects can be achieved without increasing the number of parts, and in this embodiment, there is no need to form the inner surface of the instrument body 11 into a reflective surface.

It should be noted that the present invention can of course be applied to lighting fixtures other than the above-mentioned undershelf lights, and also in the conventional lighting fixtures explained using FIGS. It can be implemented by making the length approximately the same as the width of one side as an L-shape.

〔Effect of the invention〕

According to the present invention configured as described above, the lamp socket is mounted by making the metal fitting L-shaped and attaching it to the end of one side of the sheet metal appliance body over almost the entire length, and attaching the metal fitting to the end of the one side of the metal fitting. By making it possible to fit the cap-shaped side plate using the cover plate that overlaps the outer surface as a guide, the waving deformation that occurs at the end of the sheet metal instrument body becomes an obstacle to the side plate fitting work. This makes it easy to fit the side plate to the end of the instrument body, improving assembly workability.
