ABSTRACT OF THE DISCLOSURE A lamp comprising a concave mirror; a light source located at the focus of said concave mirror; a lens means provided in front of said concave mirror and said light source comprising a central portion for allowing light from said light source to pass directly outward therethrough, and a peripheral portion around said central portion for providing directivity with the light reflected from said concave mirror by allowing the light to pass outward therethrough. The improvement comprises an annular reflector provided on the peripheral portion of the central part inside said lens means for reflecting light emitted from said light source toward said peripheral portion of said lens means back towards said concave mirror past said light source. Light reaching the concave mirror from the annular reflector and light reaching the concave mirror directly from the light source are directed toward the lens in directions parallel to the axis of the light source, thereby providing enhanced illumination by the lamp.
