摘要： A lamp unit is provided. The lamp unit includes a light emitting element disposed on an optical axis so as to face in a direction substantially orthogonal to the optical axis, a first reflector facing the light emitting element to forwardly reflect light from the light emitting element, and a direct light control member disposed in front of the light emitting element for controlling direct light directed toward a region in front of the first reflector from the light emitting element without being incident on the first reflector. The direct light control member includes a first lens portion which deflects a first portion of the direct light in a direction approaching the optical axis, and an extended portion extending from the first lens portion. The extended portion controls a second portion of the direct light differently from the first lens portion.

摘要： 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.
