Abstract: An illumination device and method are provided for controlling light-emitting diodes (LEDs). The LEDs (specifically, the LED loads) are controlled, e.g., brightness and color of the LED loads, independent of a phase-cut dimmer applied to the AC mains feeding a DC power supply. The power supply is active dependent upon the duration of a conduction angle supplied from the dimmer. The power supply, however, produces drive currents that are independent from the conduction angle by using a two-stage power supply and a relatively slow and fast control loops that are controlled through a microprocessor-based control circuit. Parameters stored in the control circuit are drawn by the microprocessor to control the two-stage power supply to produce the drive currents independent and decoupled from the conduction angle yet dependent on the controller parameters.

Abstract: A load control system may include multiple control devices that may send load control messages to load control devices for controlling an amount of power provided electrical loads. To prevent collision of the load control messages, the load control messages may be transmitted using different wireless communication channels. Each wireless communication channel may be assigned to a load control group that may include control devices and load control devices capable of communicating with one another on the assigned channel. A control device may send load control messages to a load control device within a transmission frame allocated for transmitting load control messages. The transmission frame may include equal sub-frames and load control messages may be sent at a random time within each sub-frame. Control devices may detect a status event within a sampling interval to offset transmissions from multiple control devices based on detection of the same event.

Abstract: A mobile device that is configured for wireless communication may be configured to operate as a remote control device in a lighting control system, controlling one or more lighting control devices of the lighting control system. The remote control device may control the light intensity in a space, for instance at a location of the remote control device, in response to an ambient light intensity measured at the remote control device. The remote control device may define a user interface for receiving an input that indicates a desired light intensity at the location. The remote control device may measure the ambient light intensity at the location via a light detector, compare the measured ambient light intensity to the desired light intensity, and cause the one or more lighting control devices to adjust the ambient light intensity at the remote control device until it agrees with the desired light intensity.

Abstract: Wireless devices may perform modified carrier sense multiple access (CSMA) techniques in order to increase reliability while maintaining a reasonable latency for communications. The wireless devices may perform listen-before-talk (LBT) techniques using an adaptive transmission threshold (e.g., an adaptive CSMA threshold). The transmission threshold may be compared to a measured signal strength magnitude to determine whether the frequency channel is quiet enough for transmission of a packet. The transmission threshold may be initially set to equal a minimum value. The wireless device may increase the transmission threshold after each instance of LBT failure to allow the wireless device to get progressively more likely to transmit the packet each time LBT fails.

Abstract: A two-wire load control device may be configured to compute an accurate estimate of real-time power consumption by a load that is electrically connected to, and controlled by, the two-wire load control device. The load control device may be adapted to measure a voltage drop across the device during a first portion of a half-cycle of an AC waveform provided to the device. The device may be further configured to estimate a voltage drop across the load during the second portion of the half-cycle. The estimated voltage drop may be based on the measured voltage drop. The device may be further configured to measure a current supplied to the load during a second portion of the half-cycle. The device may be configured to estimate power consumed by the load based on the measured current and the estimated voltage drop.

Abstract: A load control device for controlling power delivered from an AC power source to an electrical load may comprise a thyristor, a gate current path, and a control circuit. The control circuit may be configured to control the gate current path to conduct a pulse of gate current through a gate terminal of the thyristor to render the thyristor conductive at a firing time during a half-cycle of the AC power source. The control circuit may operate in a first gate drive mode in which the control circuit renders the gate current path non-conductive after a pulse time period from the firing time. The control circuit may operate in a second gate drive mode in which the control circuit maintains the gate current path conductive after the pulse time period during the half-cycle.
