Abstract
An optical system includes a light guide member, a prism, and a plurality of light control bodies. The light guide member includes an incident surface on which light is incident, and a first surface and a second surface facing each other. In the light guide member, the second surface is an emission surface of light. The prism is provided on the first surface and reflects light passing through the light guide member toward the second surface. The plurality of light control bodies are positioned between light sources and the incident surface. The plurality of light control bodies control light rays output from the light sources and incident on the incident surface. Each of the plurality of light control bodies includes an incident lens. Each of the plurality of light control bodies causes the light incident on the incident lens from the light source to be incident on the incident surface.
