1. A light emitting diode lighting assembly comprising:

  • driving circuitry adapted to receive an electrical excitation signal from a DC input varied in intensity by a dimming device that actuates to increase and decrease voltage of the electrical excitation signal;

    said driving circuitry comprising a first plurality of light emitting diodes in a first path in parallel relation to a second plurality of light emitting diodes in a second path;

    said first plurality of light emitting diodes having a first threshold voltage and said second plurality of light emitting diodes having a second threshold voltage greater than the first threshold value;

    a current limiting device within the first path to limit current within the first path;

    a resistor in series relation with the current limiting device and the second plurality of light emitting diodes;

    wherein as voltage increases above the second threshold voltage the resistor actuates the current limiting device to prevent flow of current to the first plurality of light emitting diodes.
