| description | A vehicle light (80) comprising a light source(81b), a major reflecting surface (82) reflecting light rays from the light source (81b) to the forward, a projection lens(88) for converging light rays incident thereto by a predetermined degree, a shutter (89) located in an optical path from the light source (81b) to the projection lens (88) for cutting off an unnecessary portion of light rays on formation of a light distribution pattern, comprising: a first movable reflecting surface (84) of an ellipse group reflecting surface having a first focus approximately on the light source (81b) and a second focus at a predetermined position, capable of being inserted in or removed from an optical path from the light source (81b) to a second fixed reflecting surface (86) by rotational movement around its longitudinal axis; a first fixed reflecting surface (85) of a parabolic group reflecting surface which has a concave surface when viewed in a direction facing to the forward of the vehicle light (80), having a focus approximately on the second focus of the first reflecting surface (84) for reflecting light rays from the first reflecting surface (84) to a predetermined front area of the vehicle light (80), comprising at least two second reflecting surface elements (85a, 85b); and a second fixed reflecting surface (86) having a first focus approximately on the light source (81b) comprising at least two third reflecting surface elements (86a, 86b) for reflecting light rays into a predetermined forward direction to be incident to the projection lens (88), which light rays have traveled its corresponding optical path from the light source (81b) thereto without being reflected by the first movable reflecting surface (84). |
