1. A light module, comprising:
a plurality of lighting elements, each lighting element having four corners, and including: one or more light emitting diodes (LEDs); an LED driver circuit to provide constant current to the LEDs and receive modulated control information, the LED driver circuit configured to control activation and dimming of the LEDs on the lighting element; a power block operatively coupled with the LED driver circuit, the power block having two power terminals of a first polarity electrically coupled together and physically disposed on opposite corners of a first diagonal the corresponding lighting element, and two power terminals of a second polarity electrically coupled together and physically disposed on opposite corners of a second diagonal of the corresponding lighting element, such that any two adjacent power terminals of one power block have opposite electrical polarity; the lighting elements being connected vertically and horizontally to an adjacent lighting element to form a predetermined pattern of lighting elements on the light module, including a first lighting element connected to a second lighting element in any of four ninety-degree rotational orientations so that an electrical connection is made between two adjacent power terminals of a side of the first lighting element and two adjacent power terminals of a corresponding side of the second lighting element; the power block further including a plurality of diodes and one capacitor, and operatively connected to the power terminals, and configured to provide the modulated control information to the corresponding LED driver circuit and provide the modulated control information to adjacent lighting elements through the power terminals of the first and second polarity without regard to the electrical polarity of the power terminals, based on a selected rotational orientation of the first or second lighting element. |
