Headlamp for vehicle

A method of manufacturing a headlamp for a vehicle comprising:

• disposing a light source behind a rear focal point of a projection lens, wherein the light source has an optical axis extending in a longitudinal direction;
• arranging a reflector to reflect light from the light source toward the projection lens;
• and
• disposing a plurality of pattern forming sections on a rotary shade, wherein each of the plurality of pattern forming sections respectively forms a corresponding light distribution pattern including an upper part irradiation pattern and a lower part irradiation pattern;
• rotatably disposing the rotary shade so as to shield a part of the light projected from the light source and reflected by the reflector,
• wherein a center of the lower part irradiating patterns is located lower than a horizontal line, and
• wherein a center of the upper part irradiating patterns is located above the horizontal line.

A headlamp for a vehicle comprising:

• a projection lens which projects light forward;
• a light source disposed behind a rear focal point of the projection lens and having an optical axis extending in a longitudinal direction;
• a reflector which reflects light from the light source toward the projection lens;
• and
• a rotary shade which is rotatable and shields a part of the light projected from the light source and reflected by the reflector,
• wherein the rotary shade comprises a plurality of pattern forming sections, each of which respectively forms a corresponding light distribution pattern including an upper part irradiation pattern and a lower part irradiation pattern,
• wherein a center of the lower part irradiating patterns is located lower than a horizontal line,
• wherein a center of the upper part irradiating patterns is located above the horizontal line,
• wherein the respective pattern forming sections of the rotary shade comprises a plurality of projections and reflecting surfaces, both of which extend in a rotary axis thereof and are provided along a circumferential direction thereof,
• wherein each of the respective projections shields a part of the light emitted from the light source to form the respective lower part irradiating patterns,
• wherein each of the respective reflecting surfaces reflects a part of the light emitted from the light source to form the respective upper part irradiating patterns,
• wherein respective pairs of the projection and the reflecting surface form the respective light distribution patterns,
• wherein the respective upper part irradiation patterns in the light distribution patterns are different from each other, and
• wherein the light distribution patterns are switched in accordance with a running state of the vehicle.
