Abstract
This relates to a light emitting diode circuit wherein a coil is connected to a voltage source, the voltage of which is lower than the threshold voltage of the forward diode characteristic. The light emitting diode is connected in series via the coil to the voltage source, and a transistor operating as a switch is connected in parallel to said light emitting diode.
