Abstract:
A vehicle lamp device includes a matrix-type image light source, a projection lens, an aperture stop and a vehicle lampshade. The projection lens is disposed downstream from and in a light path of the image light source, and the projection lens consists essentially of two or three lenses with refractive powers. The aperture stop is disposed between two outermost lenses respectively at two opposite ends of the projection lens. Two outermost lens surfaces at the two opposite ends of the projection lens have a first optical center and a second optical center respectively, and a distance between the first optical center and the second optical center is in a range between 30 mm and 85 mm.
