ABSTRACT:
A flame simulating device includes a substantially translucent shell having a hollow interior, a plurality of colored light sources, positioned within the hollow interior of said shell and a light source driving device for selectively activating each of said plurality of light sources. Each of the light sources are alternately and individually activated to have active periods and such that the surface of said shell is illuminated to produce an animated flame effect. In one example implementation, yellow, orange and red LEDs are positioned at varying heights within the flame-shaped shell and activated on and off in a sequence that follows a set of color transition rules in order to provide a close simulation of the flickering of a flame. During their active periods, LEDs are blinked on and off to conserve power.
