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 producing devices located within the imitation candle device, each light producing device positioned at an inclined angle with respect to a vertical axis of the imitation candle device and configured to project light from a distance onto the flame element including an area of overlapped light beams in a central area of the flame element;
a color sensor located inside the imitation candle device to receive reflected light from a surface that the imitation candle device is placed on and to detect a color of the surface;
one or more colored lighting devices positioned to illuminate an exterior wall of the imitation candle device; and
an electronic circuitry coupled to the color sensor, to the plurality of light producing devices and to the one or more colored lighting devices, the electronic circuitry to control projection of light produced by the plurality of light producing devices onto the flame element to simulate an appearance of a candle flame, the electronic circuitry further configured to receive a signal indicative of the color of the surface from the color sensor and to adjust illumination provided to the exterior wall based on the signal indicative of the color of the surface.

Abstract
Imitation candle devices and systems with enhanced features enable simulation of a realistic candle flame using multiple angled light sources that illuminate a surface area of a movable imitation flame element in a controlled manner. In some implementations, the imitation candle devices further include a color detection module that adjust the color of the imitation candle device based on a sensed color of the surface a surface that the candle rests upon.

12. A light-emitting control assembly for use in an electronic candle, comprising:
-
a plurality of light producing devices, each light producing device positioned at an inclined angle with respect to a vertical axis that passes through center of the light-emitting control assembly and configured to project light from a distance onto the flame element to illuminate a particular area of a flame element, wherein the angle is configured to allow the plurality of light producing devices to project a set of overlapping light beams, wherein the overlapping light beams form an overlapped area in a central area of the flame element; a circuit board comprising a microcontroller coupled to the plurality of light producing devices and the flame element to simulate an appearance of a flame upon projection of the overlapping light beams on the flame element; and one or more colored lighting devices positioned to provide illumination to an exterior wall of the electronic candle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
