Abstract:
1. A surface illumination fixture comprising: a surface illumination light-source device converting light from a point light source having strong directivity into surface illumination; and an illumination fixture main body holding the surface illumination light-source device, the surface illumination light-source device including a casing having a flat plate part being used to attach the surface illumination light-source device to the illumination fixture main body, a lateral plate part standing from the flat plate part, and an opening on a surface opposite to the flat plate part, and including a plurality of such point light sources disposed on the flat plate part, and a light-guide reflection plate covering the opening, the casing and the light-guide reflection plate being formed by members having a high light reflectance and a low light transmittance, the light-guide reflection plate being divided into regions corresponding to the point light sources, and each region being formed to have a lower light reflectance and a higher light transmittance as the distance from the corresponding point light source increases, wherein the casing and the light-guide reflection plate are formed into an annular shape.
