Description

[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a lighting fixture that has a plurality of light sources in the fixture body and a plurality of shades that individually cover each of these light sources.

(Prior art) As this type of lighting equipment, conventionally, for example,
As shown in the drawings and FIG. 5, there is a device in which a single-cap lamp 2 and a shade 3 are attached to each corner of a rectangular device body 1 whose upper and lower surfaces are flat in the horizontal direction. That is, this lighting fixture has a fixture main body 1
The opening 4 of the upper surface of the shade 3 is fitted into the corner of the shade 3, and the edge 6 of the opening 4 of the shade 3 is placed on the upper surface of the flange portion 5 of the instrument main body 1, and the opening joined to the lower surface of the instrument main body 1. The shade 3 is attached to the instrument body 1 by screwing a set screw 9 into a screw hole (not shown) provided on the lower surface of the instrument body 1 through a through hole 8 provided at the edge 7 of the section 4; each shade 3
A single-base lamp 2 is connected to a lamp socket (not shown) provided on the lower surface of the appliance main body 1 and arranged vertically inside the device.

(Problems to be solved by the invention) In the conventional lighting equipment as described above, since the single-cap lamp 2 is disposed vertically, the lower surface of the equipment body 1 is flat, and the through hole 8 of the shade 3 is Although it is easy to match the screw hole on the lower surface of the main body 1, when the single-cap lamp 2 is disposed diagonally to increase the reflection efficiency, the lower surface of the instrument main body 1 is curved, so the shade 3 and the The fitting with the lower surface is not uniform, and the through hole 8 of the shade 3 and the screw hole on the lower surface of the instrument body 1 are difficult to match, making it difficult to attach the shade 3 with the set screw 9.

In addition, since the set screw 9 and the edge 7 of the shade 3 are close to the filament part of the single-cap lamp 2, if the head of the set screw 9 and the shade 3 are made of resin, the single-cap lamp 2 Easily deteriorates due to heat generation.

In addition, since the shade 3 is fixed only at the upper part, if an external force is applied to the lower side of the shade 3, especially if it is pulled outward, the edge 7 where the set screw 9 is attached is likely to be damaged. , the lower part of each shade 3 tends to be misaligned, which impairs the appearance.

The present invention was developed in view of the above-mentioned points, and is capable of sufficiently withstanding external forces applied to the shade, and also allows the shade to be applied to the main body of the device regardless of the shape of the reflective surface on the lower surface of the main body. It is an object of the present invention to provide a lighting fixture that can be mounted, is not easily affected by heat generated by a light source, and has a good appearance by uniformly spacing the lower part of each shade.

(Structure of the Device) (Means for Solving the Problems) The present invention provides a lighting device having a plurality of light sources in the device body and a plurality of shades that individually cover the light sources, wherein the shades are arranged in the upper part of the lighting device. A shade attaching part is provided on the top surface of the device body to be fitted and fixed thereto, and a shade connecting part is provided in the lower part to be integrally connected to another shade by a retaining ring.

Next, the operation of this embodiment will be explained.

First, in assembling, the upper part of the shade 31 is fitted between the partition members 27 of the instrument main body 11, and the mounting piece 37 at the upper end of the shade 31 is fitted between the positioning guides 15 on the upper surface of the instrument main body 11. At the same time, the set screw 62 is screwed into the screw hole 16 of the instrument body 11 through the through hole 38 of the attachment piece 37 and fixed. on the other hand,
As shown in FIG. 2, the lower part of the shade 31 is assembled by fitting the protrusion 42 of each connecting piece 41 of the adjacent shade 31 into the fitting recess 43. After each connecting piece 41 is assembled, each engaging claw 5 of the retaining ring 51 is
3 into the insertion hole 44 of each connecting piece 41 from below, and in this inserted state rotate the retaining ring 51 (second
By rotating counterclockwise in the figure, the claw portion 54 of the engaging claw 53 is caused to go over the stopper 47 and fit into the end surface of the stopper 47. When the retaining ring 51 is attached, the retaining pawl 53 is sandwiched between the stopper 47 and the edge of the guide hole 45 and does not rotate in the falling direction opposite to that when the retaining ring 51 is attached. The guide ribs 48 of each connecting piece 41 fit inside the peripheral edge 52 of the connecting piece 41 to suppress rattling.

Then, as shown in FIG. 3, a single-cap lamp 63 as a light source is connected to the lamp socket 20 inside each shade 31, a starter 64 is connected to each starter socket 23, and a switch 2 is connected.
2, the switch switching hook 65 pulled out from
It hangs downward through.

In the lighting fixture assembled as described above, the upper part of each shade 31 is attached to the fixture body 11, and the lower part of the shade 31 is integrally connected by the retaining ring 51. Even if an external force is applied, the external force is dispersed to the other shades 31, so that the external force can be sufficiently withstood, and the attached state of the shade 31 is stabilized.

Furthermore, since each connecting piece 41 of the shade connecting portion 39 of the shade 31 is assembled by fitting the protrusion 42 and the fitting recess 43, each connecting piece 41 is positioned and the retaining ring 51 can be attached. Not only is it easy to do, but it also increases the strength of the connection.

Further, by connecting the lower portions of the plurality of shades 31 with the retaining ring 51, the arrangement intervals of the shades 31 can be maintained uniformly, and the appearance can be improved.

Furthermore, since the shade 31 is attached to the instrument body 11 using the set screw 62 on the top surface of the instrument body 11, the set screw 62 and the shade 31 are not located near the filament part of the single-cap lamp 63.
These synthetic resin parts are hard to deteriorate, and even if the reflective surface 17 of the device main body 11 has a curved shape with high reflection efficiency as in the above embodiment, there is no problem in attaching the shade 31 to the device main body 11. do not have.

Note that when removing the shade 31 from the instrument body 11 for cleaning etc., first remove the retaining ring 51.
Push up upwards and rotate it in the opposite direction to that at the time of installation (rotate clockwise in Fig. 2) to tighten the locking pawl 53.
The claw portion 54 is made to go over the stopper 47 and face the insertion hole portion 44, and in this state, by lowering the stop ring 51, the locking claw 53 is removed from the insertion hole portion 44, and the connecting piece 41 is connected. The shade 31 can be removed from the instrument body 11 by releasing the screw 62 that attaches the attachment piece 37 to the instrument body 11.

[Effect of idea]

According to the present invention, the upper part of the shade is attached to the upper surface of the main body of the device, and the lower part of the shade is integrally connected to other shades by the retaining ring.
The shade attachment condition is stable and can withstand the action of external force sufficiently, and by attaching the upper part of the shade to the upper surface of the instrument body, the shade can be attached to the instrument regardless of the shape of the opposite side of the lower surface of the instrument body. Not only can it be attached to the main body, it is less susceptible to heat generation from the light source, and by connecting the lower parts of multiple shades with a retaining ring,
The spacing at the bottom of each shade is kept uniform, resulting in a good appearance.
