초록

A surface lighting device receiving incident rays through two opposing faces of a light guide from light source to emit the incident rays from a face different from the two faces. The light guide is divided into plural divisions which are jointed together.

대표청구항 ▼

A surface lighting device provided with a light source and a reflection board to reflect rays of light emitted from the light source forward, wherein the color of said reflection board is set against a standard color within a range of -2.0 to 0 at D1976L*a*b*, wherein L* denotes psychometric lightness, a* denotes psychometric perceived chromaticity in the red-green region, b* denotes psychometric perceived chromaticity in the blue-yellow region of CIE1976, a uniform color space defined using a three-dimensional rectangular coordinate system adopted at the Commission Internationale de l\Eclainage, and DD2 than a reference color, and smaller by 0 than the reference color at an initial state, and when the reflection board is continuously illuminated for 10,000 hours, the D2, and the reference color is a color directly above the light source.
