Claims

[Claims for Utility Model Registration] Two inner rotating parabolic mirrors that reflect parallel rays tilted at angles opposite to each other with respect to the optical axis of the lamp and substantially share each other's focal points; a reflector consisting of an outer paraboloid of revolution mirror that continuously reflects light rays parallel to the optical axis of the lamp on the outside of the paraboloid of revolution, and that substantially shares the focal point of the inner paraboloid of revolution mirror; A vehicular lamp comprising: a light source disposed approximately at the focal point of a reflector; and a lens disposed in front of the reflector and having one type of narrow diffusion prism formed on the back surface.
