Abstract
A luminaire is provided with a light source, and a light guide which is positioned in front of the light source. The light guide includes a first surface portion formed on the light source side, and a second surface portion formed on a side opposite the first surface portion. The first surface portion is constituted by a flat surface, and the second surface portion is constituted by an inclined surface which intersects at an angle other than a right angle against the optical axis of the light source. An angle formed between the inclined surface and the optical axis on the side of the light source is smaller on a center side of the second surface portion positioned on the optical axis, and is larger on a peripheral side of the second surface portion.
