Abstract
In preferred aspects, the present invention comprises an electric fireplace designed to simulate a combustible fuel-burning fireplace.

The firebox contains a log and ember set having one or more artificial logs positioned above an artificial bed of embers. The fireplace also comprises a mechanism for illuminating the underside of at least a portion of the artificial logs and a portion of the artificial bed of embers so as to create the illusion that the artificial logs and the artificial bed of embers are burning. The fireplace further comprises a flame simulation assembly for generating the appearance of simulated flames emanating from the artificial logs. The flame simulation assembly comprises a light source, a light randomizer, a light filter screen, and a light diffuser screen. The light randomizer comprises a rotating hollow cylinder having openings that permit light to pass through the cylinder. The light filter screen has an opaque area and a colored translucent area through wh…
