Illumination apparatus

摘要

An illumination apparatus includes light sources; a light guide plate guiding lights from the light sources; a housing holding the light sources and the light guide plate; and an apparatus attachment part. The light sources are arranged around the apparatus attachment part 5, and the light guide plate 3 is provided outside the apparatus attachment part to face the housing and cover a front side of the light sources. The light guide plate includes a main light guide part guiding lights from the light sources toward an outer periphery of the light guide plate and scattering and emitting the lights to a surface of the main light guide part; and an auxiliary light guide part integrated with the main light guide part at an inner peripheral side of the main light guide part and guiding and emitting the lights from the light sources toward the central portion of the housing.
