Patent

CA 2242720

The present invention discloses a high speed programmable electronic current driver circuit for supplying a controlled modulated current to an LED comprising: a current driver operable over a selectable range of current levels for connection to an LED for supplying operating current to an LED; control means connected to the current driver to select the current level for operation of the current driver; transmission gating means connected to the current driver to gate high speed data signal pulses to the current driver to modulate the current of the current driver by the data signal pulses by gating the current of the current driver with the data signal pulses; whereby light output by the LED will be modulated by the data signal pulses at selectable current levels.
