(Problem) To provide a lighting device with a broad light distribution in which the light from an LED light source is led near to the center of the lighting device. (Means of Resolution) Lighting device provided with LED board (3) on which LED element (8) is mounted, and lighting circuit board which powers LED element (8), having a plurality of U- shaped light guides (95) positioned above LED element (8), LED element (8) being mounted on the lower surface of the two bases of light guides (95), and the plurality of U-shaped light guides (95) characterized in crossing over each other. Light from LED elements (8) mounted on the lower surface of the base of the light guides (95) is led by light guides (95) near to the center of the lighting device, with light from LED elements (8) able to have a broad light distribution due to diffusion over a wider area including the vertical and horizontal directions of the board surface of LED element (8). |
