PROBLEM TO BE SOLVED: To provide a lighting device capable of reducing glare and color unevenness by mixing light emitted from a plurality of light sources while restraining light loss.SOLUTION: In the lighting device, a base board 141 having an approximately circular opening at an approximate center is of a plate shape. The plurality of light sources 142 are mounted on one of the surfaces of the base board 141, and are arranged at a location surrounding the opening. A lens 170 has an approximately torus shape, and refracts light emitted from the plurality of light sources 142. A bottom face section 181 of a reflection section 180 is arranged in opposition to the base board 141, and reflects the light refracted with the lens 170 to emit it outside through the opening of the base board 141. |
