Abstract

An apparatus for generating light may be comprised of a light source with a lens interposed in a light path from the light source. The lens may be comprised of two or more sections wherein at least one section may be comprised of smart glass. Electrical circuitry may be configured to control a transparency state of the smart glass lens sections. Another embodiment may have two reflectors wherein one of the reflectors may be interposed between the light source and the other reflector and may be comprised of smart glass with a transparent state and a reflective state so that two different reflection patterns may be created. A method for illumination wherein at least one area's illumination is controlled by a section of smart glass is also disclosed.
