Abstract:
1. An illumination device that irradiates an irradiation surface, the illumination device comprising: a plurality of point light sources each including a light emitting surface; a first reflective member disposed between the light sources and the irradiation surface; and a second reflective member disposed to face the light emitting surfaces in a direction that is orthogonal to the light emitting surfaces, wherein the first reflective member includes two reflective surfaces which face each other, and wherein the first reflective member includes rib shaped bodies including a reflective surface and disposed in a passageway side of light emitted from the light sources, wherein a distance between the reflective surfaces which face each other increases with increasing distance away from the light sources, and wherein each rib shaped body is situated at a position of an approximately equal distance from two adjacent point light sources and is approximately orthogonal to a straight line connecting the adjacent point light sources.
