PROBLEM TO BE SOLVED: To provide a lighting device capable of optimizing a lighting beam direction of indirect lighting by adjusting a position of a light source part.SOLUTION: A lighting device 1 comprises position adjustment mechanisms 5 capable of adjusting a light irradiation direction of light source parts 4 provided with an LED 6. The position adjustment mechanisms 5 comprise supporting shafts 15 becoming shafts when the light source parts 4 are turned and movable parts 16 rotatably attached to the supporting shafts 15. The movable parts 16 have light source parts 4. The light source parts 4 and the movable parts 16 are integrally turned. When a fastening element 17 for fastening the supporting shafts 15 and the movable parts 16 is loosened, the movable parts 16 can be turned to enable the rotating positions of the light source parts 4 to be adjusted. In turn, when the fastening element 17 is fastened, the supporting shafts 15 are pushed against the movable parts 16 and the movable parts 16 may not be moved. With this arrangement, a position of each of the light source parts 4 in their turning direction is fixed.SELECTED DRAWING: Figure 6 |
