1. An imitation candle device, comprising:
- a flame element shaped to resemble a candle flame and protruding from top of the imitation candle device;
a plurality of light emitting elements located within the imitation candle device and positioned to illuminate a plurality of areas on the flame element;
electronic circuitry coupled to the plurality of light emitting elements to selectively modulate an intensity of each of the plurality of light emitting elements to simulate a flame movement in both a vertical and a horizontal direction, wherein selective modulation of the plurality of light emitting elements includes generation of electric signals to modify an intensity of one or more of the plurality of illuminated areas positioned on a lower section of the flame element to simulate a movement of the lower section of the flame element separately from one or more other illuminated areas on the flame element.

Abstract
Imitation candle devices and systems with enhanced features enable simulation of a realistic candle flame using multiple light sources that illuminate a surface area of an imitation flame element in a controlled manner. The disclosed imitation candle devices further allow the candle to be turned on or off by pushing down on the flame element, thus eliminating a need for additional external switches.

22. A light-emitting control assembly for use in an electronic candle, comprising
a plurality of light emitting elements positioned at an angle with respect to a vertical axis that passes through center of the light-emitting control assembly, each of the plurality of light emitting elements projecting a spot of light for illuminating a particular area of a flame element, the plurality of light emitting elements positioned to project a set of partially overlapping light spots and a set of substantially non-overlapping light spots; - and
a circuit board comprising a microcontroller coupled to the plurality of light emitting elements to produce electrical signals to modulate an intensity of a first group of light emitting elements separately from a second group of light emitting elements and to simulate an appearance of a moving flame in both a vertical and a horizontal direction upon projection of the overlapping light spots and the substantially non-overlapping light spots on the flame element. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
