Claims

[Scope of utility model registration request]

A light source is arranged in a lamp chamber defined by a housing and a front lens, and the front lens has a central part facing the light source and a circumferential side part at one end thereof, and a side part of the light source corresponding to the circumferential side part. A side lens and a lateral total reflection lens on the other side are each disposed substantially parallel to the optical axis, and a large amount of light from the side lens is made to enter the peripheral side of the lens. The housing is provided with a reflective surface portion and a reflective portion that reflects the light emitted backward from the light source toward the center of the lens, and the side lens has an optical axis on the inner surface that reflects the incident light from the light source and the side total reflection lens. an incident light control prism that controls light in a direction substantially perpendicular to the direction of the lens, and an output light control prism that causes light to enter the reflective surface portion on its outer surface, and the side total reflection lens has an incident light control prism on its inner surface and an output light control prism on its outer surface. and a total reflection prism configured to reflect the incident light onto the side lenses.
