Description

[Detailed explanation of the idea] This invention relates to a lighting fixture with two lights in parallel.

As shown in Fig. 1, a conventional lighting fixture for two lights in parallel has socket bases 2 and 3 attached to the end of a fixture main body 1 with a groove-shaped cross section so as to be able to hang down and expand. Fix the lamp sockets 4 and 5 to the lamp sockets 3 and 3 respectively, fix the fixture body 1 to the ceiling surface 6 in this state, and protrude the lamp sockets 4 and 5 from the socket through holes 7a and 7b on both reflective surfaces of the Fuji-shaped reflector plate 7. Cover the device body 1 with the Fuji-shaped reflector 7 in this state,
The Fuji-shaped reflector 7 was attached to the instrument body 1 by screwing thumbscrews 8°9 through the Fuji-shaped reflector 7 into the socket stands 2 and 3, respectively.

The other end of the instrument body 1 has a similar configuration.

Such a conventional parallel two-lamp lighting fixture is designed to minimize the width of the socket through holes 7 a and 7 b of the Fuji-shaped reflector 7 to improve the appearance from below the socket base 2 .
, 3 are configured to be able to hang and expand freely, and the socket stands 2, 3 are initially kept in a hanging state, and as the amount of protrusion of the lamp sockets 4, 5 from the socket through holes 7a, 7b increases, the lamp sockets 4, 3 are configured to be able to hang down and expand. I am trying to expand 5.

However, in such a configuration, one thumb screw 8, 9 is required for each of the socket stands 2, 3 in order to attach the Fuji-shaped reflector 7, and four screws are required for the entire device.
The manufacturing cost was high, and the Fuji-shaped reflector 7 was not easy to attach and detach.

Therefore, an object of this invention is to provide a lighting fixture for two lights in parallel, which can reduce manufacturing costs and also allow easy attachment and detachment of the Fuji-shaped reflector.

A first embodiment of this invention is shown in FIGS. 2 to 6.

That is, as shown in FIGS. 2 and 3, this lighting fixture for two lights in parallel has first and second socket stands 11 and 12 arranged in parallel at the end of the fixture main body 10, which has a groove-shaped cross section. The first and second lamp sockets 13.14 are fixed to the lower surfaces of the first and second socket bases 11.12, which are attached so as to be freely downwardly and expandable as shown by arrows A and B.

The first and second socket bases 11.12 have first and second through holes 15, 16, respectively, at mutually opposing locations.
are provided with a reflector mounting portion 17a, and extending on both sides of the reflector mounting portion 17a, the first and second socket bases 11. and first and second rising portions 17 b, 17 C that slide in the directions of arrows F and G within the second through holes 15 and 16, and the first and second rising portions 17 b, 17 C. a reflector mounting root 17 having first and second inwardly bent portions 17 d and 17 e that are provided at the tips of the socket bases 11 and 12 to prevent the first and second socket bases 11 and 12 from expanding beyond a certain level; connects the first and second socket bases 11,12.

In addition, as shown in FIG.
By lifting the Fuji-shaped reflector 19 toward the instrument body 10, the first and second socket through-holes 19 arranged in parallel at the ends of both reflective surfaces of the Fuji-shaped reflector 19 are opened.
a, 19b to expand the first and second socket bases 11.12 which are in a hanging state,
In this state, screw the thumbscrew 20 into the screw hole 17f of the reflector mounting portion 17a through the through hole 19C at the center of the end of the Fuji-shaped reflector 19 to attach the Fuji-shaped reflector 19 to the instrument body as shown in FIG. 10, and by tightening the thumbscrews 20, abutment occurs between the first and second socket bases 11.12, the reflector mounting base 17, and the Fuji-shaped reflector 19, and the connection between them is caused. It is securely fixed without wobbling.

First and second socket bases 11.12 and instrument body 10
means through holes 11a, 12a and through hole 10, respectively.
A, 10 and B are provided and connected in a chain so that they can freely hang down and expand.

Further, as shown in FIGS. 3 and 6, retaining pieces 17g and 17h are cut and raised at the inwardly bent portions 17d and 17e of the reflector mounting root 17, respectively. , through holes 15. of the first and second socket bases 11.12.
16 is formed with notches 15 a and 16 a for insertion of retaining pieces, and the reflector mounting plate 17 is inserted into the first socket base 11 as shown by arrow C, for example.

In this case, the dimensions w, t, w', t' of each part are t
<t'.

W) is set to satisfy W'.

In addition, 23 is a fixture end plate, 24 is a discharge lamp ballast, 25 is a ceiling mounting bolt, and 26 is a nut.

As described above, in the parallel two-lamp lighting fixture of this embodiment, the socket bases 11.12 are attached to the end of the fixture body 10 in a parallel state so that they can hang down and expand.
The lamp socket 13.1 is connected to the socket through-holes 19a and 19b of the Fuji-shaped reflector 19 by connecting it with a reflector mounting plate 17 that maintains its expandable state and prevents it from expanding beyond a certain level.
4, the socket bases 11 and 12 are expanded and the Fuji-shaped reflector 19 is attached to the reflector mounting base 17 with the thumbscrews 20, so there are two in total, one at each end of the instrument body 10. 20 thumbscrews,
At 20, the instrument body 10 and the socket stand 11.12, 11.1
2, the reflector mounting plate 17.17, and the Fuji-shaped reflector 19 can be reliably and firmly fixed, manufacturing costs can be reduced compared to conventional methods, and the Fuji-shaped reflector 19 can be easily attached and detached. .

A second embodiment of this invention is shown in FIG.

That is, this lighting fixture for two lights in parallel has retaining pieces 17i and 17 instead of retaining pieces 17g and 17h shown in FIG.
j is formed by bending, and the other configurations and effects are the same as those of the first embodiment.

A third embodiment of this invention is shown in FIG.

That is, in this lighting fixture for two lights in parallel, a slit 21 is formed in place of the through hole 15 of the socket base 11 in FIG. 6, and a claw 22 is formed in the opening of the slit 21, as shown by the arrow. After the reflection plate mounting plate 17 is inserted, the claw 22 is folded back as shown by arrow E to close the opening of the slit 21.
The reflection plate mounting plate 17 is prevented from coming off from the slit 21, and the piece for preventing the reflection plate mounting plate 17 from coming off is omitted.

The effects of this embodiment are similar to those of the second embodiment.

As described above, the parallel two-lamp lighting fixture of this invention has a main body and a first and second light fixture, which are attached to the end of the main body of the fixture so as to be able to hang down and expand in parallel, and are located at opposing positions, respectively. first and second socket stands having through holes;
First and second lamp sockets fixed to the lower surfaces of the first and second socket bases, a reflector mounting section, and the first and second lamp sockets extending on both sides of the reflector mounting section. first and second rising portions that slide within the first and second through holes in response to drooping and expansion of the socket base;
Provided at the tips of the first and second rising portions, the first
and a reflector mounting portion having first and second inwardly bent portions that prevent the second socket base from expanding beyond a certain level, and first and second reflector mounting portions that are arranged in parallel at the ends of both reflective surfaces. a Fuji-shaped reflector for expanding the first and second socket stands in a hanging state by passing the first and second lamp sockets through the socket through-holes; and an end portion of the Fuji-shaped reflector. Since the mounting screw is provided to attach the Fuji-shaped reflector to the instrument body by passing through the center and screwing into the reflector mounting portion, the number of mounting screws is smaller than in the conventional example, and manufacturing costs can be reduced. In addition, there is an effect that the Fuji-shaped reflector plate can be easily attached and detached.
