Abstract: A luminaire includes multiple light emitting cells. Each light emitting cell has a light source, and a focus-tunable lens (e.g., a liquid lens) associated with the light source. Each respective one of the light emitting cells is independently controllable relative to the one or more other light emitting cells. In a typical implementation, the control of each light emitting cell may involve, for example, controlling a surface of liquid in the corresponding liquid lens.

Abstract: A light mixing and folding lamp includes an LED assembly with two or more LED chips that direct light into the ingress end of a light mixing rod. The light mixing rod is positioned to pass through an aperture in a concave second reflecting element, and mixed light emerges from the egress end of the light mixing rod, where it is directed toward a first reflecting element positioned near a focal point of the second reflecting element. The first reflecting element reflects mixed light emerging from the egress end of the light mixing rod, folding the mixed light back toward a concave reflecting surface of the second reflecting element. The second reflecting element reflects light from the first reflecting element forward, where the light emerges from the lamp directed toward a subject to be illuminated.
