Abstract:
1. A vehicle light comprising: a light source; a major reflecting surface reflecting light rays from the light source forward; a projection lens for converging light rays incident thereto; a first shutter located in an optical path 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 having a first focus approximately on the light source and a second focus, and capable of being inserted in or removed from an optical path from the light source to a second fixed reflecting surface by rotation; a first fixed reflecting surface of a parabolic group reflecting surface having a focus approximately on the second focus of the first reflecting surface for reflecting light rays from the first reflecting surface to a front area of the vehicle light, including at least two second reflecting surface elements; the second fixed reflecting surface including an ellipse group reflecting surface having a first focus approximately on the light source including at least two third reflecting surface elements for reflecting light rays to its corresponding second focus, which light rays have traveled a corresponding optical path from the light source to the third reflecting surface element without being reflected by the first reflecting surface; a third fixed reflecting surface including a parabolic group reflecting surface including at least two fourth reflecting surface elements, each having a focus approximately on the second focus of the corresponding third reflecting surface element, for reflecting light rays from the third reflecting surface element to a front area of the vehicle light; and at least one second shutter located in at least one optical path from the third reflecting surface element to the fourth reflecting surface element for prohibiting a portion of light rays directed to the corresponding fourth reflecting surface element.
