  • Patent number: 11232724
    Abstract: A plurality of individually controllable LED modules (LEDs) are provided for displaying defined patterns. At least a first and second cables are provided with three or more conductive wires insulated from one another comprising at least one reference voltage wire, a positive voltage wire and a data wire. Each of a plurality of strips is maintained between the cables along a defined longitudinal distribution and receives the reference voltage, the positive voltage and the data therefrom. Each of the strips comprises a subset of the individually controllable LEDs positioned therealong in a defined transverse distribution. The display controller module comprises a processor that sends lighting instructions for the LEDs over the data wire. The lighting instructions are set considering the defined longitudinal distribution of the plurality of strips and the defined transverse distribution along each of the plurality of strips to provide the defined patterns.

  • Patent number: 10368422
    Abstract: A signal-preserving power booster and a related method. An input module, comprises a reference port and two input ports, receives an input light signal, which conveys an input lighting power component at a first power level and a data-over-light digital stream component imperceptible to a human eye. A MOSFET amplifier module, having access to the reference port, provides an output light signal between two output ports, a first output port being connected to an internal amplifier circuit connected to the first input port and a second output port being connected to the second input port. The output light signal conveys the data-over-light digital stream component from the input light signal and an output lighting power component, at a second power level equal to or greater than the first power level, the output light signal powering an array of LEDs at the second power level.

  • Patent number: 9797559
    Abstract: There is a provided a lighting system comprising a first cable and a second cable for receiving a voltage difference. The first cable extends between a first pair of installation locations and the second cable extends between a second pair of installation locations. The lighting system also comprises a plurality of light emitting diode (LED) strips, each LED strip electrically connected to and extending between the first cable and second cable. The lighting system also comprises a cable tensioner system coupled to the first cable and second cable for adjusting the tension of the first cable and second cable.
