ABSTRACT:
A vehicle light can include a projector type unit and an ellipse-parabola combined unit that surrounds a light source. Part of the light from the light source is directed toward a projector lens by part of an ellipse group reflecting portion of the projector type unit. The remainder of the light is directed toward a parabolic group reflecting portion of the ellipse-parabola combined unit by the ellipse group reflecting portion of the ellipse-parabola combined unit via openings. This parabolic group reflecting portion then directs the light to its illumination direction. This can improve light utilization efficiency, and the entire front face of the vehicle light can be lit without deteriorating from the vehicle light's light distribution.
