Abstract: An example of a power and modulation circuit utilizes a very high frequency switching power converter to supply drive current power to cause a solid state light source to emit light. The power converter is configured to convert power from a power source to direct current to supply via the output to the light source, at least in part by a switching function of the power converter at a very high frequency rate. The circuit, in such an example, also includes a control circuit coupled to be responsive to input data and control operation of the power converter so that the current output to drive the light source modulates the light emitted from the light source to also carry the input data.

Abstract: Disclosed herein is a lighting device including a luminaire having a first light emitter configured to output image and a second light emitter configured to output illumination light. The first light emitter is oriented with the second light emitter such that an available output region of the second light emitter at least substantially overlaps an available output region of the first light emitter. The lighting device also includes a processing system coupled to a driver system, which is coupled to the luminaire. The processing system, via the driver system, is configured to operate the first light emitter to output the image and operate the second light emitter to output the illumination light; and during the operations of the first and light emitters to output a combined light via the substantial overlap, to control the output of at least one of the image or the illumination light to control flicker due to interaction of a portion of the image and a portion of the illumination light.

Abstract: Networked intelligent lighting devices may utilize visual light communication to perform autonomous neighbor discovery, for example, as part of a map generation process. Individually, each intelligent lighting device within an installation transmits a series of packets via visual light communication for receipt by one or more of the other intelligent lighting devices. Receiving intelligent lighting devices record the number of received packets from each transmitter. Records of numbers of received packets are conveyed via a data communication network to a centralized process. The centralized process utilizes the conveyed records to determine neighbor relationships between lighting devices, for example to generate a map of devices as located within the installation.

Abstract: A cellular electrowetting array, e.g. for a luminaire, includes a liquid container having opposing transparent windows. The container contains conductive and non-conductive liquids. A grid wall extends from one of the windows at least partially across the interior volume of the container toward the opposite window. The grid wall divides the interior volume into cellular fluidic optics, each containing some conductive liquid and some non-conductive liquid. The individual cells may be square, although other shapes may be used. A first electrode electrically connects to the grid wall; and a second electrode contacts the conductive liquid. System examples combine such an electrowetting array with a positive or negative lens array, e.g. optically coupled to one of the windows of the array. The electrowetting array or a system combining that array with another lens array may be utilized in a luminaire, e.g. to provide a tunable distribution of the general illumination output.
