摘要： A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.

摘要： A rear lamp unit control system for a vehicle including: a first lamp provided on a vehicle body side of a vehicle rear face; a second lamp provided on an opening-closing body side of the vehicle rear face; and a controller configured to control the first lamp and the second lamp. When an opening-closing body of the vehicle is in a closed state, the controller is configured to control the first lamp and the second lamp so that the first lamp and the second lamp turn on at different luminous intensities to each other. In response to the second lamp being in need to be turned on when the opening-closing body is in an open state, the controller is configured to turn the first lamp on at a luminous intensity that is equivalent to a luminous intensity of the second lamp when the second lamp is turned on.
