Abstract: An adjustable floor or table lamp has a diffuser globe surrounding a light source for providing general diffuse light in a room, and an adjustable reflector above the diffuser for reflecting a portion of the light and thereby intensifying the light in a reading area. The diffuser may be open at its top for directing brighter light to the reflector and thus to the reading area. The reflector may be a two-sided mirror, with one side planar and the other non-planar, with the mirror mounted on a horizontal pivot axis over the diffuser and light source. In other embodiments an adjustable lamp includes multiple mirrors receiving light from a single source and reflecting it in concentrated beams in different directions. A small mirror may be positioned between a larger mirror and the light source, or the mirror closer to the source may be partially transmissive, or both mirrors may be together in a compound gimbaled apparatus, with the mirrors separately adjustable.
