Surface illumination fixture and surface illumination device

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 a disc shape.

• 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 includes partition plates dividing the point light sources and standing from the flat plate part in an upright manner, and the partition plates divide the casing into segments.

• the casing and the light-guide reflection plate being formed by members having a h 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 surface illumination light-source device includes both the casing and the light-guide reflection plate each having an annular shape, and the casing and the light-guide reflection plate each having a disc shape.
