ILLUMINATING APPARATUS

摘要

An illuminating apparatus includes a light source and an optical member that is disposed in front of the light source and controls light distribution of light emitted from the light source. The optical member has a pair of principal surfaces, and a plurality of prisms extending in one direction are provided on at least one among the pair of principal surfaces. The plurality of prisms include a plurality of reflecting prisms that are provided in a first region A among two regions divided at a virtual plane including a reference axis and emit light entered upon reflecting it at a reflecting surface and a plurality of refracting prisms that are provided in a second region among the two regions and emit light entered upon refracting it at a refracting surface.
