Abstract
An apparatus for simulating flames includes a light source, a viewing screen capable of diffusing and transmitting light, a rear reflector disposed behind the viewing screen, and a light producer for producing moving beams of light. The light source is disposed below the reflector and behind the viewing screen. The light producer is disposed in front of the light source and below the screen and light from the light source is reflected by the light producer onto the reflector and is reflected by the reflector onto the screen to produce a perceptible image viewable on the screen.
