Abstract
An LED light is operated in both continuous steady output and, as desired, a periodic high power burst of light that drives the LED beyond its rated output for short periods. A single cost effective circuit to perform both types of control delivers highly regulated output under both high power burst mode and continuous mode while maintaining maximum feedback resolution in the primary (continuous) output mode. Active elements are used to switch the signals from conventional current sensing elements through a controlled scaling network before joining the rest of the regulating circuit. This results in ability to produce a high efficiency, well-regulated, fast rise and fall, rectangular average peak value waveform, electric current pulse to power a single or combination of LEDs to a high output level, effecting a transition between a constant lighting level and a higher output, pulsed duration lighting level for photographic and motion image capture.
