  • Dimming control for illumination systems
    Patent number: 9402289
    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.
