Vehicle light with movable reflector portion and shutter portion for selectively switching an illuminated area of light incident on a predetermined portion of the vehicle light during driving

A vehicle light comprising:

• a light source;
• a major reflecting surface reflecting light rays from the light source forward;
• a projection lens converging light rays incident thereto;
• a shutter located in a light passageway from the light source to the projection lens for cutting off an unnecessary portion of light rays on formation of a light distribution pattern;
• a first reflecting surface including an ellipse group reflecting surface located at a side of the major reflecting surface, having a first focus approximately on the light source and a second focus, for reflecting light rays from the light source to the second focus;
• a second reflecting surface including an ellipse group reflecting surface, having a first focus approximately on the light source and a second focus, and capable of being inserted in and removed from an optical path from the light source to the first reflecting surface by rotating;
• a third reflecting surface including a first element having a focus substantially on the second focus of the second reflecting surface;
• and
• a fourth reflecting surface having a focus approximately on the second focus of the first reflecting surface, and reflecting light rays incident thereon to a front area;
• wherein the first element reflects light rays from the second reflecting surface toward a side direction in front of the vehicle light when the second reflecting surface is inserted at least partly in the optical path.

• a second reflecting surface including an ellipse group reflecting surface having a first focus approximately on the light source and a second focus, and capable of being inserted in and removed from a first area in the vicinity of an optical path from the light source to the first reflecting surface by rotation;
• a third reflecting surface including at least one first element having a focus approximately on the second focus of the second reflecting surface, for reflecting light rays incident thereon to a front area;
• wherein the shutter includes a fixed portion and a movable portion which overlaps at least partly with the fixed portion, capable of lateral movement between a fully inserted position and a removed position relative to an optical path from the light source to the projection lens,
• and the second reflecting surface reflects light rays incident thereon to the third reflecting surface when the second reflecting surface is located at least partly in the optical path, while the light rays, which are incident to the first area and not reflected by the second reflecting surface, are reflected by the first reflecting surface to be incident to the projection lens, the projection lens converges light rays incident thereto in a forward direction;
• and the movable portion of the shutter is moved relative to the fixed portion together with the second reflecting surface such that a cut-off portion of the light distribution pattern is varied.

A vehicle light, comprising:

• a light source;
• a projection lens converging light rays incident thereto;
• a reflector for reflecting light rays from the light source to the projection lens;
• a shutter located on an optical path from the light source to the projection lens, the shutter configured to cut off an unnecessary portion of light rays on formation of a light distribution pattern, the shutter including;
• a fixed portion which is fixedly located,
• a movable portion which at least partly overlaps the fixed portion and is capable of lateral movement between a fully inserted position and a removed position relative to the optical path;
• wherein a shape of the cut-off portion of the light distribution pattern of the vehicle light can be varied by movement of the movable portion relative to the fixed portion.
