Abstract: An active damping circuit is disclosed, which includes a peak current limiter, a drain source voltage limiter, a turn-on driver, a resistor shunt circuit, and a peak current sensor. The peak current sensor detects a rising edge of an input voltage from a phase cut dimmer by detecting a higher peak current. This drives a collector voltage of a second transistor of the peak current limiter low, which lowers a gate voltage of a first transistor of the peak current sensor, and forces it into a linear operating region, so it functions as a damping resistor. When the peak current sensor detects a decreased peak current, such that the turn-on edge of the input voltage is passed, the second transistor turns off, and the turn-on driver turns the first transistor on, such that the active damping circuit is waiting for a next edge of the input voltage.

Abstract: Examples relate to a method and implementations of general illumination light emitters, an image display device and an image diffuser in a luminaire. The image display device is configured to output an image having a reduced, or first, pixel image fill factor and, as a result, might appear pixelated. To mitigate the pixelation, the image diffuser has a predetermined image diffusion angle and is a predetermined distance from the image display device. The image diffuser outputs an image having a second image pixel fill factor that is greater than the first image pixel fill factor. The appearance of the outputted image appears to be formed from fuzzy pixels. Characteristics related to the image, device, diffuser, and their arrangement may be optimized to provide the fuzzy pixels. A luminaire may output an image formed of the fuzzy pixels and general illumination lighting to an area.
