Abstract
A lighting apparatus includes a light emitting element, a light flux controlling member which controls light distribution so as to narrow the light emitted from the light emitting element, a substantially tubular prism member which is formed of an optically-transparent material, has a plurality of prism rows, and extends in the optical axis direction, and a substantially tubular diffusion member having optical transparency and a light diffusion property. The plurality of prism rows is disposed parallel to the optical axis on the outer peripheral surface of the prism member.
