Abstract
A vehicle light can include a bulb, a projector lens disposed in front of the bulb and having a focus located in between the bulb and the projector lens. A first reflecting surface can be disposed behind the projector lens, for reflecting light beams emitted from the bulb toward the projector lens so that the light beams are converged at or near the focus of the projector lens. A shade can be configured to shield part of the light beams directed from the first reflecting surface to the projector lens. A second reflecting surface can be disposed on a rear surface of the shade, for reflecting downward part of the reflected light beams directed from the first reflecting surface to the projector lens. A third reflecting surface can be disposed below the shade, for reflecting the light beams from the second reflecting surface to an outside area below the projector lens to project the light beams forward. A decrease in the parts number along with an improvement in light utilization efficiency may be realized with certain embodiments of the invention.
