摘要 [Purpose] To provide a surface illumination fixture using a point light source having strong directivity. [Constitution] In the surface illumination fixture 3 including a surface illumination light-source device 6 converting light from a plurality of point light sources 36 having strong directivity into surface illumination and an illumination fixture main body 41, the surface illumination light-source device 6 includes a casing 30 having a flat plate part 35 being used to attach the surface illumination light-source device to the illumination fixture main body, lateral plate parts standing from the flat plate part, and an opening on a surface opposite to the flat plate part, and includes a light-guide reflection plate covering the opening. The flat plate part 35, the lateral plate parts 32 and 33, and the light-guide reflection plate 40 are formed by members having a high light reflectance and a low light transmittance. The light-guide reflection plate 40 is formed to have a lower light reflectance and a higher light transmittance as the distance from the corresponding point light source increases. The illumination fixture main body 41 having attaching means for attachment to a ceiling or a wall.
