摘要： A lamp unit for a headlamp of a vehicle includes a projection lens, a light emitting device disposed on a rear side of the projection lens, a reflector, and a mirror member having an upwardly reflecting surface. The reflector forwardly reflects light from the light emitting device toward an optical axis, and the upwardly reflecting surface upwardly reflects part of the light reflected by the reflector. The upwardly reflecting surface includes a first horizontal surface disposed on a self-lane side of the optical axis, a second horizontal surface disposed on an opposing-lane side of the optical axis, and an intermediate slope surface connecting the first and second horizontal surfaces. The intermediate slope surface includes a front slope surface and a rear slope surface on the rear side of the front slope surface, and the rear slope surface is curved.

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, and a reflector arranged so as to cover the light-emitting element from above and to reflect the light from the light-emitting element forward toward the optical axis. A mirror member is provided 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 is constituted with a horizontal plane including the optical axis. A shielding projection that shields the reflected light from the reflector deflected by the horizontal plane is formed in a position of the horizontal plane that is apart from the front end edge of the upward reflecting surface to a rear side.

摘要： A vehicular lamp forms a low-beam distribution pattern by combining light radiated from a first unit and a second unit. A brightness decreasing element is provided on a reflective surface of a first main reflector in a sub-unit of the first unit. Thus, for the low-beam distribution pattern formed by the first unit and the second unit, among a peripheral end portion of a cut-off line forming pattern formed by the sub unit, a low luminance portion with a partially reduced brightness is formed at the border of both right and left end sides that upwardly overlap with a portion of a diffusion area forming pattern.
