摘要： A lamp unit for a vehicular headlamp includes: a projection lens arranged to have an optical axis extending in a vehicle longitudinal direction; a light-emitting element that is a light source arranged on a rear side with respect to a rear focal point of the projection lens; and a reflector that is formed so that a longitudinal section of the reflector has the shape of an ellipse having a first focal point at a center of light emission of the light-emitting element and a second focal point at the rear focal point of the projection lens, wherein the reflector is arranged to cover the light-emitting element and reflects irradiated light toward the projection lens, the irradiated light being light irradiated from the light-emitting element. A major axis of the ellipse, passing through the first focal point and the second focal point, is inclined with respect to the optical axis.

摘要： In a vehicle headlamp, a light source image forming device forms a first light source image and a second light source image. A projection lens projects the first light source image and the second light source image so as to have a common border with each other. The light source image forming device forms the first light source image and the second light source image at positions spaced apart from each other along respective edges forming the common border.
