Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture having a box-shaped fixture body provided with a reflector.

[0002]

2. Description of the Related Art Conventionally, a lighting fixture having a reflector is provided with a fixture body 1 which is embedded in a mounting surface such as a ceiling surface (not shown) as shown in FIG. The outer peripheral portion of the rectangular upper plate portion 2 is bent downward substantially vertically to form a side plate portion 3, and an opening 4 is formed on the lower surface side of the side plate portion 3 to form a substantially box shape.

The side plate portion 3 in the longitudinal direction of the instrument body 1
The lamp socket 5 is attached to the lamp socket with a lamp socket fitting (not shown).

Further, an upper end plate 8 of a reflector 7 having a reflecting surface 6 that spreads downward so that the plane becomes a substantially isosceles trapezoid is attached to the upper plate portion 2 of the instrument main body 1 by a decorative screw 9. Has been.

A lamp 10 is connected to a lamp socket 5 arranged inside the side plate portion 3 in the longitudinal direction so as to face the inner surface of the upper end plate 8 of the reflector 7.

Then, it is formed on a mounting surface such as a ceiling,
The device body 1 is inserted into a mounting opening slightly larger than the device body 1 to be mounted so that the opening 4 of the device body 1 and the mounting surface are flush with each other.

[0007]

However, in the luminaire having the above-mentioned conventional structure, it is necessary to perform attachment / detachment work with a plurality of decorative screws 9 when attaching / detaching the reflector 7 for mounting / maintenance of the luminaire main body 1 and maintenance. There is a problem that the work becomes complicated and the material cost is increased.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lighting apparatus in which the material cost can be reduced and the reflector can be easily attached and detached.

[0009]

The luminaire of the present invention is provided with a reflector which has a lamp therein and which has an opening formed on the lower surface and which has a reflecting surface which spreads downward to reflect the irradiation light of the lamp. A lighting fixture including a box-shaped fixture main body having a side wall, the box-shaped fixture main body is provided on the opposing side walls and is formed by expanding upward to lock the lower end of the reflector. And an abutting portion that is provided between the side walls and that abuts the upper end of the reflector and urges downward.

[0010]

In the lighting apparatus of the present invention, the reflector has its lower end locked upward by an engaging portion provided on the side wall of the apparatus body and having an inclined surface that expands upward, and the upper end is fixed to the apparatus. It is urged downward and supported by an abutting portion provided on the upper surface of the main body.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the lighting equipment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 11 denotes an instrument body, and the instrument body 11 is bent substantially vertically downward from an outer peripheral edge portion of a substantially rectangular upper plate portion 12 to form a side plate portion 13 as a side wall. However, the side plate 13 is formed in a substantially box shape in which an opening 14 is formed on the lower surface side.

Lamp socket fittings 15 suspended in the width direction are attached to opposite side plate portions 13 at both ends in the longitudinal direction of the fixture body 11, and the lamp socket fittings 15 are attached to the lower flat portions 16 on the lower surface thereof. A lamp socket 18 is attached to which the fluorescent lamp 17 is engaged so as to project in the direction, and which is mounted electrically and mechanically. Then, on the lower flat portion 16 of the lamp socket mounting member 15, a protruding portion 19 which is located on the center side of the appliance body 11 of the lamp socket 18 and serves as an abutting portion that protrudes downward is bulged and formed.

Further, the side plate portion 13 in the longitudinal direction of the instrument body 11
An engaging portion 21 that is cut and raised inward so as to be substantially perpendicular to the side plate portion 13 is provided in the lower part of the. This engaging portion 21 is
It is formed in a substantially inverted V shape so as to form an inclined surface 22 that widens toward the upper plate portion 12 of the device body 11.

Reference numeral 23 is a reflector as a reflector, and the reflector 23 has a swash plate portion 25 bent downward from an upper end portion 24 formed on the upper surface so as to form a substantially isosceles trapezoid. .. The tips of these swash plate portions 25 are bent outward to form support portions 26. Furthermore, in these swash plate portions 25, the distance between the support portions 26 at the lower end of the swash plate portion 25 is
The side plate 13 is formed to be slightly wider than the facing distance A of the engaging portion 21 of the side plate 13. Further, a reflecting surface 27 is formed on the inner surface of the reflecting plate 23 which is expanded.

Next, the operation of this embodiment will be described.

At the time of construction, for example, a fluorescent lamp 17 is installed in a mounting opening formed in a mounting surface such as a ceiling plate (not shown).
Insert the instrument main body 11 with the reflector plate 23 not attached, and fix the instrument main body 11 with screws (not shown) such that the periphery of the opening 14 is flush with the front surface of the attachment surface. To do.

Next, as shown in FIG. 3, the lower end of the swash plate portion 25 of the reflection plate 23 is set to the distance A facing the engagement portion 21 of the side plate portion 13.
Bending inward so that it becomes narrower, and pushing up until the upper end 24 of the reflector 23 hits the flat surface 16 of the lower surface of the lamp socket mounting bracket 15, and then opening it, the protrusion 19 of the lamp socket mounting bracket 15 is opened. And the engaging portion 21 provided on the side plate portion 13
It is point-supported and locked to the instrument body 11.

Next, attach each fluorescent lamp 17 to each lamp socket.
Connect to 18.

When the reflector 23 is detached from the instrument body 11, the lower end of the swash plate portion 25 of the reflector 23 is attached to the side plate portion.
It is bent inward so as to be narrower than the facing distance A of the engaging portion 21 of 13 and is removed downward.

According to the above construction, the reflecting plate 23 is the engaging portion provided on the projecting portion 19 of the lamp socket fitting 15 and the side plate portion 13.
Since it is supported at 3 points by 21 and locked to the instrument body 11,
The attachment / detachment work of the reflection plate 23 is performed only by bending the reflection plate 23, and it is not necessary to attach the reflection plate 23 with a separate screw or the like, and the attachment / detachment work can be easily performed, and the installation time and maintenance management time of the instrument body can be shortened. Further, since a mounting tool such as a screw is not required, the number of parts can be reduced, the material cost can be reduced, and the parts can be easily managed.

Further, since the reflecting plate 23 is supported at three points and locked to the instrument body 11, the reflecting plate 23 can be attached to the instrument body 11 without rattling.

In the above embodiment, the reflecting plate 23 is
Even when it is simply placed on the inclined surface 22, the reflector
It is also possible that the support portion 26 of 23 is urged upward against the inclined surface 22 and locked.

[0024]

According to the luminaire of the present invention, the reflector is
The lower end is locked upward by an engaging portion provided on the side wall of the instrument body and having an inclined surface that expands upward, and the upper end is attached downward by an abutment portion provided on the upper surface of the instrument body. Since it is biased and supported, the reflector can be easily attached and detached, and the number of parts can be reduced,
Material costs can be reduced.
