1. An LED lighting circuit comprising:

  • a rectification circuit for converting an AC input power signal to a rectified DC power signal;

    a peak current limiting circuit electrically coupled to the rectification circuit for providing a peak current limiting means from the voltage ripple of said rectified DC power signal, wherein said voltage ripple is intentionally unreduced, whose output creates a current source; and

    an LED mesh circuit electrically coupled to the output of the peak current limiting circuit and receives said current source as an input;

    wherein the AC input power range is between 50 VRMS, inclusive, and 350 VRMS, inclusive, with a maximum of 20% of the AC input power allocated to the peak current limiting circuit, with said current source equal to or less than 20 mA per LED.
