PROBLEM TO BE SOLVED: To provide a lighting device for a plant, the position of the cover of which is not easily dislocated.SOLUTION: A lighting device 10 for a plant includes a base 20, a light-emitting part 40, a main body part 30, and a cover 50. The outer surface of the main body part 30 is provided with both a first ridge part 31, which restricts the movement of the cover 50 by touching the edge part of the cover 50 from the light-emitting part 40 side, and a second ridge part 32, which restricts the movement of the cover 50 by touching the edge part of the cover 50 from the base 20 side, along the circumferential direction. The inner circumferential surface of the edge part of the cover 50 is provided with a projection 52 which restricts the rotational movement of the cover 50 by touching the outer surface of the main body part 30.SELECTED DRAWING: Figure 2 |
