Claim 1:
2. The desktop illumination device according to claim 1, wherein a light distribution of the light emitted from the center of the first main surface is in a range of −90° to +90° in a horizontal direction, in a case where an axis passing through the center of the first main surface and parallel to the installation surface is defined as a horizontal axis, a direction orthogonal to a light emitting surface and extending from the center of the light emitting surface toward an emission side to which the light is emitted is defined as horizontal 0° in a plane including the horizontal axis and parallel to the installation surface, and a clockwise angle from the horizontal 0° is defined as a positive angle and a counterclockwise angle from the horizontal 0° is defined as a negative angle with respect to the plane parallel to the installation surface as viewed from a side opposite to the installation surface.
