Abstract
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.
