    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.

    Abstract: A puddle lamp including a light source composed of a single light emitting body, a lens set, a projection film with a fixed image and a projection lens is provided. The lens set is disposed at a light path downstream side of the light source. The projection film is disposed at a light path downstream side of the lens set. The lens is disposed at a light path downstream side of the projection film. An optical axis of the light source is substantially parallel to an optical axis of the lens set, and an optical axis of the projection lens is not perpendicular to an image plane of the puddle lamp. Furthermore, another puddle lamp is also provided.
