Patent ID: 7316493

Claim:
A headlamp for a vehicle, comprising: a projection lens arranged on an optical axis extending in the longitudinal direction of a vehicle; a light source arranged at the rear of a rear side focus of the projection lens, wherein the light source includes a linear light source extending in the axial direction of a light source bulb inserted and fixed to a main reflector from a side of the optical axis; the main reflector for reflecting light, which is sent from the light source, toward a front side while the reflected light is converged toward the optical axis; a shade, which is arranged near a rear side focus of the projection lens so that an upper end edge of the shade can be located close to the optical axis and which reflects a portion of the reflected light sent from the main reflector; a first addition reflector for reflecting light, which is sent from the light source, to a front region in the bulb insertion direction, and the first addition reflector being arranged between the light source bulb and the shade; and a second addition reflector for reflecting light, which is reflected on the first addition reflector being sent from the light source, toward a front side while the reflected light is converged toward the optical axis, the second addition reflector being provided at a front region in the bulb insertion direction on a reflecting face of the main reflector; wherein a reflecting face of the first addition reflector is divided into a plurality of reflecting portions, wherein a surface shape of each reflecting portion is formed into an ellipsoid of revolution, a first focus of which is a position of the light source and a second focus of which is another position between the first addition reflector and the second addition reflector, wherein the second focuses of the plurality of reflecting portions are different from one another; and wherein a reflecting face of the second addition reflector is divided into a plurality of reflecting portions, wherein the reflected light sent from the reflecting portions of the first addition reflector is incident upon the reflecting portions of the second additional reflector.
