Abstract: In a lighting device provided with a light source module including a plurality of light sources, insufficiency of luminous intensity, illuminance unevenness, and the like due to a low-light light source are compensated for. The lighting device includes the light source module which is composed of the plurality of light sources in a matrix and mounted on a board. A drive circuit individually supplies power to the light sources. A processor controls a lighting status of each of the light sources via the drive circuit. The processor determines a low-light light source that is lower in luminous intensity than at least one light source among the plurality of light sources, and causes at least one light source adjacent to the low-light light source to emit light with a higher luminous intensity than the at least one other light source.

Abstract: A light emitting device includes a light source for emitting light. A light guide includes an entrance surface that receives the light emitted from the light source. The light guide is configured to guide the received light along a length thereof in a direction away from the light source and to allow a part of the guided light to emerge outside of the light guide. A facing member includes a facing surface that extends along the length of the light guide and faces the light guide. The facing member is configured to be illuminated by the part of the light emerging outside of the light guide. At least one part of the facing member is configured to increase in luminance of the facing surface in accordance with an increase in a distance from the light source along the length of the light guide.
