However, in the conventional lighting device, since the lighting mounting member has a cantilever structure coupled to the upper end of the support via the arm, a force is applied to the lighting mounting member from either the horizontal direction or the vertical direction. Even in such a case, there is a problem that a large bending moment acts on the support column and the support of the lighting attachment member by the support column becomes unstable.
Furthermore, although either direct illumination or indirect illumination can be selected, there is also a problem that it is not possible to illuminate the top board by using both at the same time.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to stabilize the support of the illumination mounting member by the support column and to illuminate the fixture simultaneously with direct illumination and indirect illumination. Is to provide.

In order to solve the above problems, the present invention proposes the following means.
