Abstract:
A single board light engine includes an AC to AC step driver that selectively powers multiple LED segments by controlling tap points between the LED segments as the input voltage goes from zero crossover to maximum voltage and returns to zero crossover. The step driver may power a first LED segment, a second LED segment, both the first and second LED segments, or none of the LED segments depending upon the input voltage level. The LEDs within an LED segment may share a characteristic that differs from a characteristic shared by LEDs in another segment, which allows the LED fixture to provide a variety of lighting effects.
