Abstract: A load regulation device, such as an LED driver, may be configured to control the intensity of a light source based on an analog control signal and a preconfigured dimming curve. The LED driver may sense a magnitude of the analog control signal and determine a new low-end and/or high-end control signal magnitude that falls outside of the input signal range of the dimming curve. The LED driver may rescale the preconfigured dimming curve according to new low-end and/or high-end control signal magnitudes and dim the light source based on the rescaled dimming curve. Multiple LED drivers controlled by the same analog control signal may communicate with each other regarding the magnitude of the analog control signal sensed by each LED driver, and match their target intensity levels despite sensing different analog control signal. A controller may be provided to coordinate the operation of the multiple LED drivers.

Abstract: A load control system may include load control devices for controlling power provided to an electrical load. The load control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. A user device may discover load control devices when the load control devices are within an established range associated with the user device. The user device and the load control devices may communicate via a wireless communications module. The established range may be adjusted based on the configurable transmit power of the user device or the wireless communications module associated with the user device. A discovered control-target device may be associated with a control-source device to enable the control-target device to control the power provided to the electrical load based on digital messages received from the control-source device.

Abstract: A sensor and/or system controller may process an image multiple times at multiple resolutions to detect glare conditions. A glare condition threshold used to determine whether a glare condition exists may be based on the resolution of the image. When the resolution of the image is higher, the glare condition threshold may be higher. The sensor and/or system controller may organize one or more adjacent pixels having similar intensities into pixel groups. The pixel groups may vary in size and/or shape. The sensor and/or system controller may determine a representative group luminance for the pixel group (e.g., an average luminance of the pixels in the group). The sensor and/or system controller may determine a group glare condition threshold, which may be used to determine whether a glare condition exists for the group of pixels and/or may be based on the size of the group.

Abstract: An LED lamp and method are provided for autonomously changing the output brightness and color temperature of a plurality of LED strings to follow a first dimcurve in temporal synchronization with at least one other LED lamp. Synchronization is achieved based on a time of day determined using a clock signal. The output brightness and color temperature can transition from the first dimcurve to a second dimcurve over a predetermined number of scenes. The number of scenes is a function of a difference between the first dimcurve and the second dimcurve in at least one of the output brightness and the color temperature.

Abstract: A load control system may be commissioned using beacons. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacons are received. The control devices may provide feedback to a user in response to confirmation messages to indicate to a user that the lighting control device has been added to the temporary group. The control devices may stop providing the feedback after they are removed from the temporary group.

Abstract: A load control device may be controlled via a gesture performed by a user on a display of a mobile device. For example, the intensity level and/or the state of an electrical load controlled by the load control device may be controlled via gesture. The gesture may be a press and drag gesture. The mobile device may receive an actuation of an icon representing the load control device for at least a predetermined amount of time, and may enter a load control mode. The mobile device may detect a movement of the actuation and may determine an updated intensity level or state for the load control device based on the direction of the movement, the amount of the movement, and/or the endpoint of the movement. The mobile device may transmit one or more messages to the load control device comprising instructions configured to control the load control device.

Abstract: A control device may communicate messages with devices in a network through a parent device, and receive messages from auxiliary parent devices. The control device may store a respective communication metric associated with each of the parent device and the one or more auxiliary parent devices. The control device may set an auxiliary parent device of the one or more auxiliary parent devices as the parent device of the control device, e.g., when a respective communication metric of the auxiliary parent device determined to be set as the parent device indicates a stronger communication link than the parent device. The control device may determine that the respective communication metric of the auxiliary parent device indicates a stronger potential communication link than the parent device when the average received signal strength indicator of auxiliary parent device is greater than the average received signal strength indicator of the parent device.

Abstract: A lighting device, such as a light-emitting diode (LED) light source, may operate in an interim operable state to avoid and/or prevent undesirable characteristics in the light emitted by the lighting device (e.g., strobing and/or flickering of a brightness of the light and/or shifting or change of a color of the light). When operating in a normal state, the control circuit may determine if a measured value of a first operational characteristic (e.g., a forward voltage of an emitter of the lighting device) is outside of a range and operate in the interim operable state if the measured value of the first operational characteristic is outside of the range. When operating in the interim operable state, the control circuit may adjust a drive current for the emitter in response to a measured value of a second operational characteristic (e.g., a forward voltage of a detector of the lighting device).

The programming data may include control settings for a scene, a schedule, or an automated control feature. The programming data may be displayed for being viewed and/or adjusted by a user. The programming data may be transmitted to the control devices and/or a system controller for being implemented in performing load control.

Abstract: A two-wire lighting control device, may include a controllably conductive device, a signal generation circuit, and a filter circuit. The controllably conductive device may apply an AC line voltage to a load, being conductive for a first duration of time and non-conductive for a second duration of time within a half-cycle of the AC line voltage. The signal generation circuit may generate a non-zero-magnitude signal. And, the filter circuit may receive a signal from the controllably conductive device during the first duration of time and the non-zero-magnitude signal from the signal generation circuit during the second duration of time. The non-zero-magnitude signal may, in effect, fill-in or complement the signal from the controllably conductive device, and any delay variation as a function of the firing angle of the controllably conductive device through the filter circuit may be mitigated by the presence of the non-zero-magnitude signal.
