Abstract
A configurable lighting device may include a light source, a first lens, one or more second lenses, and a controllable optical modulator. The first lens is coupled to receive and redirect light output from the source. The second lenses are positioned to receive the light redirected by the first lens. The controllable optical modulator is between the first and second lenses. The controllable optical modulator is coupled to receive and spatially modulate light redirected by the first lens. The one or more second lenses are coupled to receive and redirect light modulated by the controllable optical modulator. The optical modulator is selectively controllable to steer and/or shape the light redirected by the first lens to a selected distribution of the light on the one or more second lenses.
