Abstract
A vehicle headlamp is provided. The vehicle headlamp includes a projection-type light source unit housed in a lamp chamber. The light source unit includes a projection lens; a shade; a light emitting diode (LED) light source; a reflector; and an optical element. The LED light source includes a substrate; an LED chip disposed on the substrate such that the LED chip is oriented in a direction substantially perpendicular to an optical axis of the light source unit; and a cover member. A region of the cover member includes concave and convex portions so as to diffuse light transmitted through the cover member. The reflector reflects and guides the light from the LED light source onto a rear focus of the projection lens. The optical element guides the diffused light transmitted through the cover toward a front side of the vehicle headlamp so as to form an overhead light distribution.
