A protrusion consisting of a reflective surface located between the straight parts and along the straight part is provided, and the light from the fluorescent lamp is reflected by the reflective surface of the bottom surface and the reflective surface of the protrusion, and is emitted from the opening of the casing. The lighting device according to the present invention, wherein the height of the protrusion formed on the bottom surface of the casing, which is a reflective surface, gradually decreases as it approaches the bent portion of the bent fluorescent lamp.
