PROBLEM TO BE SOLVED: To provide a lighting device which prevents a dark part from occurring at a center part even when having an attachment part attached to an attachment object part at the center.SOLUTION: A light emitting part 40 supported by a device body 20 receives electric power supply from a power source part 22 to light. The light emitting part 40 includes an LED group 50, which includes a large number of LEDs mounted along the same line detouring a center part of the device body 20 at predetermined intervals, on a mounting surface 411 of a circuit board 41. The LED group 50 includes first LEDs 421 which radiate light in a direction that moves away from the circuit board 41 along a thickness direction of the circuit board 41; and second LEDs 422 which radiate light toward the center part. Thus, the structure prevents a dark part from occurring at the center part even if an attachment part 21 attached to an attachment object part 11 is provided at the center. |
