Abstract
A headlamp assembly includes a light source, a first lens having a positive focal power, a second lens having a negative focal power, a third lens having a positive focal power, and a fourth lens having a positive focal power. A first side and a second side of the first lens opposite to each other are convex surfaces. A first side and a second side of the third lens opposite to each other are convex surfaces. The first, second, third, and fourth lenses are arranged from a light emitting side of the headlamp assembly to a light incident side of the headlamp assembly along an optical axis of the light source. The first, second, third, and fourth lenses define a system focal length, and a ratio of a focal length of the third lens to the system focal length is greater than 2.
