  • Publication number: 20170231055
    Abstract: Lighting systems and methods implementing toggle control are provided. In one example implementation, a lighting system can include a first LED array having one or more LED devices and a second LED array having one or more LED devices. The system can further include a single throw circuit interrupter configured to receive power from a power source. The system can further include a power conversion circuit configured to convert an input power received via the toggle switch to a power output for the first LED array and the second LED array. The power conversion circuit can be configured to control a power distribution ratio between the first LED array and the second LED array based at least in part on a detected toggle input (e.g., a toggle pattern) implemented using the single throw circuit interrupter.

  • Patent number: 9723683
    Abstract: Systems and methods for controlling a light emitting diode (LED) system having a plurality of LED arrays are provided. The lighting system can include a dimmable LED driver circuit configured to provide a driver output suitable for providing a driver current to the LED arrays. A current splitter circuit can be provided between the LED driver circuit and the plurality of LED arrays to control the ratio of current from the driver output provided to each of the plurality of LED arrays. The current splitter circuit can be configured to control the current ratio provided to the plurality of LED arrays independently of the driver output according to a current ratio control curve based at least in part on a variable reference signal provided at the current splitter circuit.

  • Patent number: 9433042
    Abstract: A device and system for controlling a light source. The device has a positive terminal and a negative terminal for setting the high-end trim of a light source, the device includes several zener diodes each having a different zener voltage; and a selector having a plurality of positions, positioning the selector in each of the plurality of positions couples a corresponding one of the zener diodes between the positive terminal and the negative terminal. The cathode of the selected zener diode is coupled to the positive terminal and the anode of the selected zener diode is coupled to the negative terminal. The selected zener diode limits the voltage across the positive terminal and the negative terminal to set the high-end trim of a 0-10 volt lighting control signal.
