Abstract
A current regulating LED strobe drive circuit is disclosed for efficiently producing a LED strobe that is consistent in both intensity and color. The circuit may include an inrush control for limiting an amount of current that is allowed to flow through the drive circuit upon activation, an energy storage component for storing and supplying power for flashing a LED, 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, and a flash control element electrically coupled to the current regulator for communicating a flash pulse signal that provides a pulsed pattern with which current is allowed to flow from the current regulator to the LED. The circuit may further include an output control having an operator interface for allowing an operator to define a desired light output level.
