Abstract: A vehicle projection lens includes a plastic aspheric first lens, an aperture stop, a cemented lens consisting of a glass second lens and a glass third lens, and a glass fourth lens arranged in order from a magnified side to a minified side. An F-number of the vehicle projection lens is smaller than or equal to 0.8, and the vehicle projection lens consists essentially of four lenses respectively with positive, positive, negative and positive refractive powers.

Abstract: A vehicle lamp device including a matrix image light source, a projection lens, and a vehicle lampshade is provided. The projection lens has an optical axis and is disposed in a downstream of an optical path of the matrix image light source. The vehicle lampshade is disposed in a downstream of an optical path of the projection lens. The projection lens includes two to three optical lenses, and a projection aspect ratio of the projection lens is between 2.5:1 and 6:1. A distance between optical centers of outermost lens surfaces at both ends of the projection lens is between 54 millimeters and 76 millimeters. In addition, a projection lens for a vehicle lamp is also proposed.

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: An optical lens includes a first lens, a light guide and a second lens arranged in order in a direction of an optical axis of the optical lens. The light guide has a first end and a second end opposite the first end, and an inner surface of the light guide touches at least a part of an outer edge of the second lens.
