Method and apparatus for driving a flashing light systems using substantially square power pulses

摘要

An enhanced method and apparatus for driving an immersed flashing light system used for enhancing algae growth is disclosed. The flashing light system includes a plurality of light source elements that are arranged to illuminate the algae. The light source elements are electrically connected to form " eta " banks of light source elements. Power is supplied to each bank of light sources in a predetermined sequence at regular intervals to substantially evenly supply each bank of light source elements with a series of power pulses while maintaining a substantially continuous load on the power supply. The power pulses are substantially half cycles of a square wave.
