DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for closing an irradiation opening of a frame with a cover.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 and 9, for example, a lighting fixture 90 of this type is provided with a mercury lamp or the like at the other end of a column 91 having a length of several meters and having one end fixed to the ground. An instrument body 94 provided with a lamp socket 93 to which the lamp 92 is mounted is fixed with bolts 95 or the like. In addition, the frame body 96 forms a top plate portion 97, a column portion 98 projecting substantially vertically below a square of the top plate portion 97, and a lower end of the column portion 98 where the frame body 96 becomes a substantially cubic body. An irradiation opening 100 is formed on the side surface. And this instrument body 94
Frame with support 101 radially attached from the side of
The base frame 99 of the 96 is fixed with bolts 102 or the like, and the frame 96 is supported.

[0003] A substantially square plate-shaped cover body 103 that closes the irradiation opening 100 of the frame body 96 and covers the main body 94 with a gap therebetween is supported. Note that each cover body 103 is guided and supported by claw portions 104 formed by projecting inward from the top plate portion 97 and the base frame portion 99 at both ends in the vertical direction. Further, the frame body 96 is provided with a cover receiving member 105 that abuts on both side edges in the vertical direction of the cover body 103 and sandwiches each cover body 103 on the inner surface side of the pillar 98 of the frame body 96 with screws 106 and the like. Attached.

The cover body 103 is provided with a claw 104 of the frame body 96.
Then, position it with reference to the edge of the column 98 of the frame body 96, attach it to the frame body 96, and secure the cover bracket 105 so that the cover body 103 does not shift. The cover body 103 is held in contact with the edge with the inner surface of the column 98 of the frame body 96, and is screwed.

[0005]

However, in the luminaire having the above-described structure, the cover 103 is guided and supported by the claw 104 of the frame 96, so that the cover 103 is restricted in the vertical direction. The direction is not restricted, and the column 98 of the frame 96 is
There is a problem that it is very difficult to securely attach and fix the cover body 103 because the positioning is performed based on the edge of the cover 103.

Further, when the cover metal fitting 105 is brought into contact with the cover body 103 and fixed with the screws 106, it is necessary to attach the cover body 103 with care so that the cover body 103 does not shift, which is troublesome.

Further, in particular, in the case where a pattern or a figure is drawn on the cover body 103, there is a problem that even a slight displacement causes a displacement of the pattern or the figure and impairs the appearance.
