    Abstract: Devices, systems, and methods to predict a half-life or end of life for luminaire drivers are described. The drivers may include electronic drivers for light fixtures such as dimming controls that utilize electrolytic capacitors in the output circuit to smooth the output current and reduce changes in current amplitude. Half-life and end of life for the drivers may be predicted by monitoring failure variable indications of the driver and the luminaire light, including the light intensity depreciation of the light, and by evaluating the data from both the driver, light, and environment in which the driver and/or luminaire is installed to predict the most imminent half-life and/or end of life.

    Abstract: Sectorized Visual Light Communication (VLC)/Dark Light Communication (DLC) systems and sensors are generally disclosed. The exemplary VLC/DLC systems may include a transmitter for transmitting a light signal including information about the transmitting light source, and a receiver with a number of surface facets facing in different directions at different angles, and configured to determine a distance and a direction of a transmitting light source from the VLC/DLC receiver. Associated exemplary methods for automatic identification and grouping of light sources are disclosed.

    Abstract: A system for transporting high luminous intensity light from at least one luminaire to a destination area is disclosed. The system may include a light guide that carries light from the luminaire to a plurality of sensors located on a Printed Circuit Board (PCB). The PCB may be attachable anywhere the luminaire is located. While collecting light rays originating from the luminaire and delivering them to the light sensors, the light guide may perform a plurality of operations to modify the characteristics of the collected light rays. The plurality of operations performed by the light guide on the light rays may support the accuracy and longevity of the light sensors on the PCB. Further, the light guide allows the sensor subsystem to be proximal to or distant from the luminaire.
