ABSTRACT:
An artificial fireplace for simulating flaming logs has a housing containing a solid state light source, a rotating flame simulation assembly, a viewing screen, and a simulated fuel source. The solid state light source preferably comprises light emitting diodes (LEDs) affixed to a printed circuit board. The light produced by the LEDs reflects off of the rotating flame simulation assembly and an image of a flame is transmitted onto the viewing screen. This design creates a realistic, randomly-flickering flame image above the simulated fuel source. Optional features include a dimmer assembly to adjust the intensity of the image and a second light source to simulate smoldering embers within the simulated fuel source. This design eliminates the problems associated with using a light bulb for a light source by instead using LEDs with a longer life span which emit less undesirable heat and consume less electricity.
