PROBLEM TO BE SOLVED: To provide a lighting device in which light emitting elements are arranged in a ring form, in which light and dark parts of a cover part are suppressed and illumination can be uniformalized.SOLUTION: In a lighting device, a light source cover member 4 for covering light emitting elements 22 is made thick and inclined and, thereby, light from the light emitting elements 22 arranged in a ring form with a simple structure without using an additional member such as a lens can be irradiated effectively in a central direction of a cover member 4, and, as a result, uniform luminance and illuminance at a cover member face can be obtained. |
