Abstract:
To provide a thin lighting device.SOLUTION: According to a lighting device 100, a projecting part 140 having a tip end part 140A functioning as a rotational support axis of a lighting fixture 110 is formed in a mountain shape downwardly projecting from a cover 130, and its tip end part 141 is formed in a downwardly protruding spherical segment shape. The projecting part 140 abuts to a downwardly recessed spherical crown shape of a second recessed part 110BC at the center of a large-diameter surface 110B of the lighting fixture 110, and functions as a support axis of the lighting fixture 110. As a result of such a structure above, in the lighting device 100, the thickness of the projecting part 140 for rotating the lighting fixture 110 is partly overlapped on the thickness of the lighting fixture 110 where the second recessed part 110BC is formed in a vertical direction, namely in a direction of the thickness of the lighting device 100.SELECTED DRAWING: Figure 1
