PROBLEM TO BE SOLVED: To increase efficiency of a headlamp for a vehicle greater than about 35%, which is efficiency of a projector type headlamp which is conventionally told efficient. SOLUTION: An auxiliary lens unit 7 provided with a light receiving lens part 71, an inner surface reflecting part 72, an outgoing radiation surface part 73 for capturing direct light form a light source 2 and projecting light in an irradiating direction of the headlamp 1 for the vehicle is provided to surround a projector unit 5 in addition to a conventional structure of the projector unit 5. Consequently, light flux capturing ratio to the light source 2 is improved to solve the problem. |
