Abstract
A current regulating LED strobe drive circuit including an energy storage component, a current regulator electrically coupled to the energy storage component for sensing and regulating a current supplied by the energy storage element, a LED electrically coupled to the current regulator, a flash control element electrically coupled to the current regulator for generating a flash pulse signal that dictates a pulsed pattern with which current is allowed to flow from the current regulator to the LED, an output control having an operator interface for allowing an operator to select a desired light output level, wherein the output control is electrically coupled to the current regulator for varying the amount of current supplied to the LED, and an inrush control including a plurality of slow charge circuits, wherein each slow charge circuit is configured to provide a respective peak current for charging the energy storage component.
