Abstract
A planar light emitting bodyconfigured to emit a first illumination light, and a semiconductor light emitting elementconfigured to emit light toward the planar light emitting bodyare disposed in a lamp chamberdefined by a lamp housinghaving an opening and a coverthat covers the opening. The planar light emitting bodyincludes a transmitting layer through which light is caused to pass, and a control layer configured to irradiate light as a second illumination light by controlling a travelling direction of the light that is emitted from the semiconductor light emitting elementand passes through the transmitting layer.
