## Abstract

An artificial flame apparatus produces a simulated flame using a plume of mist that is illuminated around, about, and through an artificial wick. A mist may be produced by a transducer, such as an ultrasonic transducer that is in contact with liquid from a liquid reservoir. The rate of mist exiting the housing may be modulated to produce a more realistic looking artificial flame. A light source is configured to illuminate the mist and/or the artificial wick. The artificial wick may be in the shape of a wick or flame and may include a light source. One or more light sources may be configured as the artificial wick. The light intensity, color and rate of change of light may be modulated to produce a more realistic looking artificial flame. A standing wave tube may vary the rate of mist exiting one or more enclosure openings in the tube enclosure.
