PROBLEM TO BE SOLVED: To provide a lighting device of high workability in attachment or detachment, and its mounting structure, even if having a long light source portion.SOLUTION: A lighting device 2 includes a mounting frame 3, and a lighting apparatus 5. The lighting apparatus 5 has a light source portion 7, and a light guide plate 6. A longitudinal direction of the light source portion 7 is positioned along one side of the mounting frame 3. The light source portion 7 includes a main body portion 71, a first restricting portion 84 disposed on a first end portion 88 of the main body portion 71, and a second restricting portion 86 disposed on a position separated to a second end portion 89 side from the first restricting portion 84 in the main body portion 71. The main body portion 71 is slidable on the mounting frame 3 in a state that the first end portion 88 is supported on a top face of the mounting frame 3, and the second end portion 89 is separated from the top face of the mounting frame 3. The first restricting portion 84 permits the movement in a sliding direction, and restricts the position in a vertical direction. The second restricting portion 86 permits the movement in the vertical direction and restricts the position in the sliding direction.SELECTED DRAWING: Figure 11 |
