Abstract: A load control device for controlling the amount of power delivered to an electrical load is able to operate in a normal mode and a burst mode. The load control device may comprise a control circuit that activates an inverter circuit during active state periods and deactivates the inverter circuit during inactive state periods. The control circuit may operate in the normal mode to regulate an average magnitude of a load current conducted through the electrical load to be above a minimum rated current. The control circuit may operate in the burst mode to adjust the average magnitude of the load current to be below the minimum rated current. The control circuit may adjust the average magnitude of the load current by adjusting the length of the inactive state periods while holding the length of the active state periods constant.

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 wireless communication device for use in a load control system for controlling one or more electrical loads may comprise a counterpoise, a first and second antennas, a RF communication circuit and a control circuit. The two antennas may be oriented differently and spaced apart from each other. For example, the first antenna may extend perpendicularly from the counterpoise while the second antenna extends in a plane substantially parallel to the counterpoise. The first antenna may extend from the counterpoise at a point substantially central to the counterpoise while the second antenna may extend along a perimeter of the counterpoise. The RF communication circuit may transmit wireless signals via the first and second antennas. The control circuit may cause the RF communication circuit to transmit a first wireless signal in a first time slot and a second wireless signal in a second time slot.

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: 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 system includes a window treatment adjacent to a window of a room. At least one motor drive unit is associated with the window treatment, for varying the position of the window treatment. A sensor measures a light level (e.g., an outdoor light level) at the window. A controller provides signals to the motor drive unit to automatically adjust the position of the window treatment so as to control a penetration distance of sunlight into the room when the window treatment is partially opened. The controller is configured to position the window treatment in a bright override position if the measured light level is at least a bright threshold value. The controller is configured to select the bright threshold value from among at least two predetermined values. The selection depends on an angle of incidence between light rays from the sun and a surface normal of the window.

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.
