Abstract
A lighting apparatus comprising a light source which emits light with predetermined light distribution in a fixed direction, and an optical element which is arranged in such a manner that at least part of light emitted from the light source inputs to the optical element, and can perform switching to a transmission state in which the light is transmitted, a first reflection state in which the light is reflected in a first direction, and a second reflection state in which the light is reflected in a second direction different from the first direction.
