Abstract
A vehicle light device includes a light guide member including a light exist portion that has light exit surfaces, and a light reflection portion that has light reflection surfaces. Each light exit surface is convex, and defines a real focal point disposed forwardly of the light reflection portion. Each light reflection surface is concaved and disposed forwardly of the light exist portion, and defines a virtual focal point superimposed on the real focal point of one of the light exit surfaces, so as to reflect light rays from a light emitter unit into the light guide member toward the respective light exit surface, such that extension lines of the light rays reflected therefrom intersect at the virtual focal point.
Claims9
A vehicle light device adapted for rearwardly projecting light rays, comprising:
- a base plate;
- a light emitter unit disposed on said base plate to emit the light rays along a left-right direction;
- and
- a light guide member including a light guide main body connected to said base plate and extending along the left-right direction, said light guide main body including a light exit portion, a light reflection portion disposed forwardly of said light exit portion, and a light entry portion that is connected between said light exit portion and said light reflection portion and that is adjacent to said light emitter unit;
- wherein said light exit portion has a plurality of light exit surfaces arranged along the left-right directions, each of said light exit surfaces being convex rearwardly to project rearwardly the light rays emitted from said light emitter unit out of said light guiding member, and defining a real focal point disposed forwardly of said light reflection portion;
- and
- wherein said light reflection portion has a plurality of light reflection surfaces arranged along the left-right direction, each of said light reflection surfaces being concaved, being disposed forwardly of a respective one of said light exit surfaces, and defining a virtual focal point superimposed on said real focal point of the respective one of said light exit surfaces, so as to reflect rearwardly the light rays entering said light guide member toward the respective one of said light exit surfaces, such that extension lines of the light rays reflected therefrom intersect at said virtual focal point.
