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 peripheral side part at one end, and a side lens on one side and a side lens on the other side, sandwiching the light source. a total reflection surface portion, each of which has a total reflection lens disposed substantially parallel to the optical axis, and allows a large amount of light from the side lens to enter a peripheral side portion of the lens on the housing side of the side lens; A total reflection lens having a total reflection part that reflects the light emitted backward from the light source to the center of the lens is disposed on the housing side, and the side total reflection lens has an inner surface that reflects the light incident from the light source. an incident light control prism that controls the light in a direction substantially perpendicular to the lens; and a total reflection prism that reflects the light from the incident light control prism toward the side lens. The lens includes an incident light control prism that directs the light incident from the light source and the side total reflection lens in a direction approximately perpendicular to the optical axis, and a total reflection surface of the total reflection lens.
A vehicular lamp characterized in that it comprises an emitted light control prism.
