Abstract
A flame simulator can include a light beam source, a range limiter, a light beam mover, a power supply, a power control circuit, and a flame screen. The light beam source can be adapted to project a movable beam of light with a circular, oval, elliptical, or otherwise round, cross-sectional shape and with an intensity, shape and/or color that mimics a flame (e.g., a candle flame) when the beam strikes the flame screen. The light beam mover can generate beam movement and the range limiter can limit the range of movement so that the beam stays mostly on the flame screen in a region bounded by the typical range of movement of a flame being simulated (e.g., a candle flame moving in response to ambient air currents). The light beam mover can cause the illumination provided by the beam to dance on the flame screen with variations in position and shape that mimic a dancing flame (e.g., a candle flame being blown about by air currents). One or more of the flame simulators can be incorporated into an imitation candle.
