Abstract: Disclosed are examples of optical/electrical devices including a variable TIR lens assembly having a transducer, an optical lens and an electrowetting cell coupled to an exterior wall of the lens. The electrowetting cell contains two immiscible liquids having different optical and electrical properties. One liquid has a high index of refraction, and the other liquid has a low index of refraction. At least one liquid is electrically conductive. A signal causes the high index of refraction and the low index of refraction liquids to assume various positions within the electrowetting cell along the exterior wall. The properties of the optical lens, e.g. its total internal reflectivity, change depending upon the position of the respective liquids along the exterior wall. The light detection characteristics of the assembly change to receive an input light beam over a range of inputs or over a range of fields of view.

Abstract: To improve efficiency, particularly for general illumination applications, a source of green or yellow light includes a solid state device (e.g. a laser diode) to produce an infrared laser beam and a light frequency up-converter to convert the infrared light into green or yellow light. A luminaire includes such a source as well as a source providing two other colors of light, such as red and blue (e.g. not green or yellow).

The luminaire outputs a combination of the various colors of lights from the sources, for example, to produce white light. If the different emitters are independently controllable, the luminaire may be adjusted or ‘tuned’ to output white light of different color characteristics and/or to output combined light of various colors over a wide region of the visible light color gamut.

Abstract: In response to determining that the line power source for a subset or all member devices of a lighting control group is interrupted, an emergency luminaire enters an emergency mode (EM) active state by controlling a light source, via a driver circuit, to continuously emit emergency illumination lighting. Upon entering the EM active state, the emergency luminaire transmits, via a wireless lighting control network, an EM active message to a lighting control group repeatedly at a predetermined time interval. Emergency luminaire receives, via the wireless lighting control network, an EM exit message from another member device indicating to exit the EM active state. In response to receiving the EM exit message from the other member device, the emergency luminaire exits the EM active state by controlling the light source, via the driver circuit, to discontinue emitting the emergency illumination lighting.
