摘要： A lamp has a deformed lamp reflector and a lamp front glass. The deformed lamp reflector is made by deforming an ellipsoid of revolution of a conventional lamp reflector into an aspherical reflection surface rotationally symmetrical with respect to an optical axis. The lamp front glass is obtained by deforming at least one of an incident surface and outgoing surface of a conventional lamp front glass into an aspherical lens surface rotationally symmetrical with respect to the optical axis. A light flux emitted from the center point of an illuminant is reflected by the deformed lamp reflector, and output with a uniform density through all of the outgoing surface of the lamp front lens so that the light flux is condensed at focus point.

摘要： Plural collimator lenses are arranged corresponding to plural laser light sources to collimate light beams emitted from the laser light sources into substantially parallel light beams, respectively. A condenser lens focuses the substantially parallel light beams. A coupling optical element, on which light beams focused by the condenser lens are incident, couples the light beams into a single light beam. The laser light sources are arranged such that a longitudinal direction of an emitting region of each of the laser light sources is coincident with a radial direction of the condenser lens.
