1. An electronic lighting device for simulating a true candle, comprising:

  • an outer shell having a shape to resemble a true candle, the outer shell structured to form an opening at a top surface;

    a core contained within the outer shell, the core shaped to form an opening at a top surface leading to an internal cavity, wherein the opening of the core is aligned with the opening of the outer shell;

    a flame component structured to include a top portion, middle portion, and bottom portion, wherein the top portion is shaped to resemble a true flame, wherein a surface of the top portion includes a plurality of regions, wherein each of at least two of the plurality of regions is covered with a corresponding light converting material converts light incident thereupon into a different color light;

    two or more light emitting elements contained entirely within the outer shell and disposed at least partially in a lighting element installation cradle on the core to emit light from within the outer shell onto the flame component through the opening of the core at an angle with respect to a longitudinal axis of the light emitting elements and a longitudinal axis of the electronic lighting device; and

    a control circuit to control the two or more lighting elements to blink at a predetermined rate, to drive the light emitting elements to produce light that is directed to the plurality of regions of the top portion of the flame component, and to produce at least two different colored regions on the top portion of the flame component upon interaction with the light converting material.
