Abstract
An electric fireplace designed to simulate a combustible fuel-burning fireplace. The electric fireplace includes a housing. A simulated firebox is positioned within the fireplace housing. The firebox contains a log and ember set having one or more artificial logs positioned above an artificial bed of embers. The fireplace also includes a mechanism for illuminating the underside of at least a portion of the artificial logs and the artificial bed of embers to create the illusion that the artificial logs and artificial bed of embers are burning. The fireplace further includes a flame simulation assembly for generating the appearance of simulated flames emanating from the artificial logs. The flame simulation assembly includes a light source, a light randomizer, a light filter screen, and a light diffuser screen.
