Abstract: Systems, software, and methods are provided for efficient, dynamic lighting control. In an embodiment, a two-channel LED lighting system is dynamically controlled to emulate dimming of an incandescent fixture. In an example, a lighting fixture may include red, green, blue, and white emitting LED modules. The lighting fixture may be controlled such that it produces generally white light from about 2150K candle light color to 5500K daylight white color with only 4 LEDs. Furthermore, the white LED may be controlled such that the white LED CRI is approximately 95 to ensure optimal results when mixed with red and green. In another embodiment, a dynamic two-channel LED lighting system is controlled to emulate dimming of an incandescent fixture. Specific dimming protocol can allow for efficient dimming which helps minimize the height of a linear light fixture and maintain diffusion with multiple colored point sources at minimal pitch.

Abstract: An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal. The signal can be provided intermittently and a carrier wave also provided and modulated at the same time as the signal. When the signal is not being produced, the power on the power line may be power that is allowed to flow without manipulation from an external portion of the power line.

Abstract: Printed circuit board (PCB) arrangements for linear lighting are disclosed. In one embodiment, an elongate, flexible PCB carries light-emitting diode (LED) light engines on one side of the PCB and components on the other. The components may be, e.g., resistors, current controllers, color controllers, or network interfaces. In another embodiment, two PCBs, each with components mounted on a single side, are connected together electrically and mechanically to function as one. In yet another embodiment, an elongate, flexible PCB has a central section that carries LED light engines and other components, and a pair of wings, one on each side of the central section. The wings carry adhesive to secure the PCB to a substrate.

Abstract: A streetlight sensor platform comprising a sensor module which is coupled to a controller section having a lower portion for interfacing with a receptacle of a streetlight and an upper portion for receiving the sensor module. The sensor module is coupled to the controller section without the need for tools allowing easy installation and replacement. The sensor can be utilized for intelligent lighting and event notification such as public safety, emergency vehicle alerts, traffic monitoring, alerts and dynamic lighting applications.

Abstract: A power and control assembly is disclosed. An LED driver is sized and adapted to fit within a single compartment of an electrical gang box. The driver has a groove or channel, and an electrical element, such as a switch, is sized to fit within the groove.

Abstract: An electrical supply system including: an extension module including a composite board having an anode layer and a cathode layer of an electrically conducting material, which anode layer and cathode layer are separated by an insulator of an electrically insulating material, the anode layer and the cathode layer each having a trench extending from a connection surface of the composite board and including a connection element, connector pins for the trenches of the extension module, each connector pin having a first complementary connection element for engaging the connection element of the trench of the composite board of a further extension module and a second complementary connection element for engaging the connection element of the trench of the composite board of the extension module, and a power supply capable of providing a constant voltage or a constant current between the anode layer and the cathode layer.
