Abstract: In accordance with various embodiments, a modular lighting system features multiple light panels each having multiple light-emitting elements thereon, as well as connectors for electrically and mechanically interconnecting the light panels.
Abstract: Changes in light intensity emitted by an illumination system are controlled by receiving signals to initiate dimming, determining a present value of the output drive signal, computing a change increment for the output drive signal based on the present value of the output drive signal, and changing the output drive signal by the change increment. The change increment is a first value if the present value of the output drive signal is less than a threshold, and the change increment is a second value greater than the first value if the present value of the output drive signal is greater than the threshold.
