  However, in the conventional illuminating device, the reflector is fixed to the column or the like by screwing. For this reason, although a reflector can be fixed reliably, tools, such as a screwdriver, are needed for attachment and detachment of a screw, and there exists a problem that much time and labor are required for attachment or detachment.

  The present invention has been made in view of such problems, and can easily attach and detach the reflection mechanism to the illumination mounting member without using a tool or the like, and can illuminate the fixture indirectly. An object is to provide an apparatus.

In order to solve the above problems, the present invention proposes the following means.
The illuminating device of the present invention has a main plate portion that is extended to a position above the fixture, and that can be attached with an illuminating lamp on the upper surface, and a pair of side plate portions that protrude vertically from both side edges of the main plate portion. An attachment member, and a reflection mechanism that is connected to the illumination attachment member and has a reflection surface that is disposed to face the upper side of the main plate portion, and the reflection mechanism is formed by connecting the pair of side plate portions of the illumination attachment member to each other. A contact portion that contacts each of the opposing inner surfaces, and an urging portion that urges each contact portion toward the inner surface of the side plate portion that contacts each contact portion, In addition, it has a locking portion for locking each contact portion.

According to this invention, the reflection mechanism is supported by locking each contact portion by the locking portion. Further, by urging each abutting portion that abuts against the mutually facing inner surfaces of the pair of side plate portions toward the inner surface of the side plate portion by the urging portion, rattling that occurs between the side plate portion and the abutting portion is prevented. Thus, the reflection mechanism can be attached to the illumination attachment member. At this time, since the reflecting surface is disposed opposite to the upper side of the main plate portion of the lighting attachment member, the illumination light emitted from the illuminating lamp attached to the upper surface of the main plate portion is reflected by the main plate portion and the pair of side plate portions. It is guided upward and is further reflected downward by the reflecting surface to indirectly illuminate the fixture.
On the other hand, the reflecting mechanism can be removed from the illumination attachment member by bringing the contact portions closer to each other against the biasing force of the biasing portion and separating the contact portions from the side plate portions.
In this way, by adjusting the distance between the contact portions, the reflection mechanism can be easily attached to and detached from the illumination attachment member without using a tool or the like.

Moreover, in the above-described lighting device, it is more preferable that the pair of side plate portions and the locking portion of the lighting attachment member are formed to extend in an extending direction in which the lighting attachment member is extended.
According to this invention, the contact portion can be moved in the extending direction with respect to the side plate portion and the locking portion. For this reason, a reflection mechanism can be slid with respect to an illumination attachment member, and the position of the extending direction can be adjusted.

In the above illumination device, it is more preferable that the reflection mechanism includes a movement preventing member that prevents the contact portions that are in contact with the inner surfaces of the pair of side plate portions from approaching each other.
According to this invention, it is possible to prevent the reflection mechanism from being detached from the illumination mounting member.

  According to the illumination device of the present invention, the reflection mechanism can be easily attached to and detached from the illumination attachment member without using a tool.
