Patent ID: 7703959

Claim:
A lamp unit of a vehicle lamp comprising: 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 comprising 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 a portion in the vicinity of the rear focal point of the projection lens, wherein a region of the upward reflecting surface located nearer a self-lane side than the optical axis comprises a first horizontal plane including the optical axis, wherein a region of the upward reflecting surface located nearer an opposite-lane side than the optical axis comprises 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, and wherein 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.
