1. A high speed programmable electronic current driver circuit for supplying a controlled modulated current to a LED comprising:

  • a current driver operable over a selectable range of current levels for connection to an LED for supplying operating current to a LED;

    control means connected to said current driver to select the current level for operation of said current driver;

    transmission gating means connected to said current driver to gate high speed data signal pulses to said current driver to modulate the current of said current driver by said data signal pulses by gating the current of said current driver with said data signal pulses;

    whereby light output by said LED will be modulated by said data signal pulses at selectable current levels.
