And FIG. 11). The pressure receiving plate 12 has a through hole 13 formed therein.

A decorative screw is used as the mounting screw 6, and the screw 6 is passed through the fixing hole 11 and the through hole 13 of the reflection plate 5 and screwed into the screw hole 4 a of the screw holder 4 to be tightened. Accordingly, the reflector 5 covering the lighting fixture main body 1 from below is connected to the fixture main body 1. The tightening force of the mounting screw 6 is applied via the pressure receiving plate 12 to the reflection plate 5.
Accordingly, the reflector 5 is pressed and held against the ceiling surface 14 to which the lighting fixture body 1 is directly attached.

[0008] The lighting apparatus S having the above configuration is shown in Figs.
As shown in FIG. 2, a pair of V-shaped recesses 15a (see FIGS. 11 and 12) corresponding to the outer surface shape of the reflector 5 are provided, and both ends in the longitudinal direction of the reflector 5 are fitted and supported there. A cardboard end buffer 15, a plurality of cardboard buffers 16 interposed between the lighting fixture body 1 and the reflector 5,
It is packaged using the outer package 17.

The outer package 17 is a single piece of corrugated cardboard, and is folded into a rectangular tube so as to integrally wrap the lighting fixture S and the end buffer 15 supporting the lighting fixture S. (See FIG. 12) and assembled, and the packaging of the lighting fixture S is completed with the assembly.

Incidentally, the buffer 16 is used to support the reflector 5 so that the reflector 5 does not inadvertently move with respect to the luminaire main body 1 during transportation or the like and collide with each other. I have.

The conventional shock absorber 16 comprises a first shock absorber plate 19 formed by bending one corrugated cardboard shown in FIG. 13 so as to form a U-shape when viewed from the end face direction with the crease 19a as a boundary, 14 and is formed by a second cardboard cushioning plate 20 provided in engagement with a first engagement groove 19b formed in the center of the first cushioning plate 19. . As shown in FIG. 12, the lower end of the second buffer plate 20 is in contact with the inner groove bottom 5c of the reflector 5.

The first engagement groove 19 is provided on the upper part of the first buffer plate 19.
A pair of second engagement grooves 19c located on both sides of b are provided. The first buffer plate 19 has an inclined lower surface 19d.
Are arranged inside the reflector 5 such that both end surfaces 19e are in contact with the inner surface of the reflector 5 and both end faces 19e in the longitudinal direction are closely opposed to the inner surface of the upper edge 5d of the reflector 5.

The lighting fixture body 1 has a side edge 1 thereof.
a is inserted into the second engagement groove 19c and supported on the first buffer plate 19, and the main body 1 is
It is supported by the buffer plate 20.

The corrugated cardboard forming the second cushioning plate 20 is used in a posture in which the corrugated paper is vertically extended so as not to be deformed by the load of the lighting fixture body 1.
Further, the first buffer plate 19 has strength in that direction in order to prevent the lighting fixture body 1 supported by the first buffer plate 19 from moving in the width direction. That is, the step of the stencil sheet of the corrugated cardboard forming the first cushioning plate 19 extends in the direction across the both end faces 19e,
In other words, it extends in the width direction of the lighting fixture body 1.

In such a conventional shock absorber 16, the compressive strength in the width direction of the lighting fixture main body 1 is obtained by the first shock absorber plate 19,
The compressive strength in the thickness direction of the lighting fixture main body 1, in other words, in the vertical direction, is obtained by the second buffer plate 19. Thereby,
The lighting fixture body 1 is supported at an appropriate position within the width of the reflector 5 so that the lighting fixture body 1 does not move in the width direction and hit the reflector 5.

[0016]

The conventional shock absorber 16 is
In order to obtain the compressive strength in the width direction and the vertical direction of the luminaire main body 1, a first compressive strength having a dedicated compressive strength in each direction is used.
Since the buffer plate 19 and the second buffer plate 20 are configured in combination, there is a problem that the number of parts and the labor of assembling are large, and thus the cost is high.

In addition, the conventional shock absorber 16 is simply interposed between the luminaire main body 1 and the reflector 5 and does not have a positioning structure for these longitudinal directions. Therefore, when the packaging device falls with the longitudinal end first, the buffer 16 may move in the longitudinal direction of the lighting fixture S. When such a movement occurs, the lighting fixture main body 1 becomes easy to move on the side from which the buffer 16 is removed, so that the intended buffering effect is impaired.

An object of the present invention is to intervene between a lighting fixture main body and a reflector, which is advantageous for minimizing the number of parts and reducing costs, and is also advantageous in that it is not located at a predetermined position. An object of the present invention is to provide a buffer for a lighting fixture capable of preventing a ready movement.

And, the first engagement plate portion is engaged with the inner surface of the lighting fixture body,
It is interposed between the lighting fixture body and the reflector. Then, the lighting fixture body is supported from below.

In this support, the tip portions of the pair of second engagement plate portions are engaged with each other and engaged with the bottom of the inner surface groove. The direction of the step of the stencil base paper in these second engagement plate portions coincides with the inclination direction of the second engagement plate portions bent obliquely. Therefore, these second engagement plate portions,
Consequently, the compressive strength in the vertical direction of the thickness-direction buffer cylinder portion is large.

The compressive strength in the width direction of the luminaire main body is large in the width direction buffer plate portion of the buffer body depending on the direction of the step of the stencil sheet. Moreover, since both end surfaces are in contact with the inner surface of the outer package body for packaging the lighting device or the inner surface of the upper edge of the reflection plate, the widthwise buffer plate portion is arranged within the width of the reflection plate. Is supported so as not to move in the width direction.

The fitting hole of the buffer fits into a screw receiving portion for mounting a reflector provided in the lighting fixture body. Thereby, the buffer is positioned and held with respect to the lighting fixture main body, and prevents the buffer from moving in the width direction and the longitudinal direction of the lighting fixture main body, respectively.

Therefore, in the cushioning body, the lighting fixture main body arranged within the width of the reflector is securely supported at a predetermined position in the longitudinal direction of the main body so as not to be moved inadvertently in the vertical and width directions. Accordingly, it is possible to prevent the lighting fixture main body from hitting the reflection plate during transportation or the like.
