PURPOSE: To provide a vehicle lighting fixture wherein a whole virtual reflection surface is glitteringly seen when a front lens is looked in a maximum reflection angle direction, by reflecting a light beam, emitted from a bulb, toward in one side and the other side maximum reflection angle directions with a line, parallel to the light axis of the virtual reflecting surface, as a boundary. CONSTITUTION: Reflecting surfaces 13c are formed so that a light beam q1, from a bulb toward the top 13b of one side diffusion prisms 13 adjoining with each other out of diffusion prisms 13, can be reflected toward the maximum reflection angle direction q1' on the other side with a parallel line to a light axis O as a boundary. Also, the reflecting surfaces 13c are formed so that a light beam q2, which is the light beam q1 extended to the other side prism 13, can be reflected toward the other side maximum reflection angle direction q2' by the other side prism 13 with a parallel line 15 as a boundary. The curved reflecting surface 13c of the prism 13 reflects a light beam, emitted from a light point 11, toward one and the other side maximum reflection angle directions with the parallel line 15, to the light axis O of a virtual reflecting surface S, as a boundary. Consequently, the virtual reflecting surface S can be glitteringly seen when a front surface lens 2 is looked from the maximum reflection angle direction. |
