The present invention relates to a method for driving at least one LED which is per- formed in the following steps: by generating a pulsating current through the LED, con- trolling the voltage drop over at least the LED and generating pulses with at least a raising flange and a falling flange. It is the object of the present invention to perform overdrive of LEDs for increasing high-peak intensities in pulsating light. The object can be achieved by generating the pulses with a sloping rising flange. Hereby it can be achieved that when LEDs are driven with sloped current increases very high-peak in- tensities can be achieved making a LED suitable for strobe and flash applications by which this driver technology opens a whole new world of applications where LEDs can be implemented. It is possible to increase the peak intensities in all applications where flashing can be accepted. |
