  • Patent number: 10582582
    Abstract: A control system for a stadium lighting system comprising a plurality of luminaires installed within the stadium to illuminate a pitch within the stadium in accordance with a light plan containing aiming information for each luminaire is disclosed. The control system comprises a data storage device storing the light plan and a controller communicatively coupled to the data storage device, the controller being responsive to object tracking information for an object travelling across the pitch. The controller is adapted to determine a direction of travel of the object from the object tracking information; evaluate the aiming information for each luminaire to identify if at least one luminaire is arranged to generate a luminous output in an aiming direction coinciding with said direction of travel; and generate a dimming level adjustment signal for the at least one identified luminaire to reduce the intensity of said luminous output.

  • Patent number: 10575383
    Abstract: An imaging sensor determines an influence of artificial light from one or more artificial light sources and an influence of natural light in an area associated with a lighting system. On the basis of the influence of the natural light and the influence of the artificial light, the imaging sensor determines the location of the one or more artificial light sources with respect to the location of the imaging sensor. Further, the imaging sensor allocates a portion of the area as an area of influence of the imaging sensor based on a threshold change in luminescence of the area associated with switching on or switching off of the one or more artificial light sources. Responsively, the imaging sensor associates at least one artificial light source of the one or more light sources and occupancy sensors corresponding to the at least one artificial light source with the allocated area of influence.

  • Patent number: 10566168
    Abstract: One or more pellicles protect a cathode, the pellicles comprised of a thin layer of material that allows electrons to pass while preventing contamination of the cathode from elements originating beyond the pellicle or contamination of an outside apparatus from elements originating on or near the cathode. The pellicle can be supported by an insulator, the insulator in turn supported by a deflecting layer. The pellicle can be maintained at a positive voltage relative to the cathode, such that a voltage gradient is created between the cathode and the pellicle that accelerates electrons emitted by the cathode away from the cathode. The pellicle is located at an appropriate distance from the cathode to allow electron transmission matching the energy of the electrons at that distance.

  • Patent number: 10524334
    Abstract: A lighting device (e.g. LED driver) includes digital dimming, configuration and firmware updating via wireless communication circuitry and associated volatile memory (e.g., SRAM). A power stage converts AC mains input into a DC bus voltage, and further converts the DC bus voltage into output current for driving a load. A power distribution circuit generates a regulated DC voltage based on the DC bus voltage. A wireless interface circuit is linked to a wireless communications network (e.g., NFC), and configured to receive device configuration data during at least first operating conditions when the regulated DC voltage is unavailable, and further to receive dimming control data during second operating conditions when the regulated DC voltage is available. A controller generates gate driving signals for regulating the output current from the power stage, said gate driving signals generated based at least in part on the device configuration data and the dimming control data.

  • Patent number: 10512132
    Abstract: A method and apparatus for a light fixture that uses current sharing across any one or more LED strings within the light fixture. A processor may determine the current requirements of the one or more LED strings that are needed to produce a given intensity level. The processor may then apportion the current generation capability of a power supply across all active LED strings using time division multiple access (TDMA) whereby each LED string may conduct its apportioned current within its allocated time slot to the mutual exclusion of the remaining active LED strings in any given time period. The processor may transition from a TDMA mode of operation to a direct drive mode of operation when the time duration of each of the mutually exclusive time slots are substantially equal to each other or within a percentage range of each other.
