  • Publication number: 20190208605
    Abstract: A network power distribution system includes a plurality of networked digitally controlled lighting devices and a network powered network controller. Each of the digitally controlled lighting devices includes a device driver that coupled to the network. The device driver is selectively transitionable between a first operating mode in which the device driver provides a first voltage and a first current to the network and a second operating mode where the driver does not provide a voltage or current to the network. The network controller autonomously determines a number of device drivers that, in the first operating mode, at least meet the current draw of the network controller. The network controller then transitions the determined number of device drivers to the first operating mode. The network controller monitors the device drivers for faults and autonomously swaps device drivers to maintain network power.

  • Patent number: 9642204
    Abstract: Systems and methods for driving solid state light sources are provided. A first drive circuit is configured to generate a drive current to cause a first solid state light source load and a second solid state light source load to illuminate. A feedback and control circuit is configured to receive feedback from the first solid state light source load and to control the drive current through the first solid state light source load based on the feedback. A second drive circuit is configured to control the drive current through the second solid state light source load. A master controller is configured to provide a first input to the feedback and control circuit to control the drive current through the first solid state light source load and a second input to the second drive circuit to control the drive current through the second solid state light source load.
