Abstract
A strobe light system for use with a camera, the strobe light system including an LED light source, a triggering signal input for the reception of a triggering signal, an electrical power source and a control circuit. The control circuit is coupled to the LED light source. The control circuit has a first transistor and a second transistor. The first transistor, the second transistor and the LED are electrically in series with the electrical power source. The first transistor is controlled to establish an electrical power level that is to be conducted through the LED. The second transistor being subject to the triggering signal to thereby electrically conduct for a predetermined amount of time thereby establishing an electrical current pulse through the LED.
