发明名称 Lamp unit of vehicle headlamp
摘要 A lamp unit of a vehicle lamp includes a projection lens arranged on an optical axis extending in the longitudinal direction of a vehicle, a light-emitting element arranged so as to face upward behind a rear focal point of the projection lens and in the vicinity of the optical axis, a reflector arranged so as to cover the light-emitting element from above and to reflect light from the light-emitting element forward toward the optical axis, and a mirror member disposed between the reflector and the projection lens. The mirror member includes an upward reflecting surface that upward reflects a portion of the reflected light from the reflector, and a front end edge formed so as to pass through the rear focal point of the projection lens. A region of the upward reflecting surface located nearer a self-lane side than the optical axis includes a first horizontal plane including the optical axis. A region of the upward reflecting surface located nearer an opposite-lane side than the optical axis includes a middle slope extending obliquely downward from the optical axis and a second horizontal plane extending parallel to the first horizontal plane from a lower end edge of the middle slope. A diffusing and reflecting portion that diffuses and reflects the reflected light from the reflector is formed in a position of the middle slope that is apart from the front end edge of the upward reflecting surface to a rear side.
