Abstract
A simulated fireplace assembly is provided having a simulated fuel bed and a screen for transmitting an image of a flame. The simulated fuel bed is located adjacent to the screen. The screen has a first region that is sufficiently reflective to reflect the fuel bed and a second region that is sufficiently non-reflective to avoid reflection of ambient subject matter that is not associated with the fireplace assembly.
Claims6
A simulated fireplace assembly having:
- a simulated fuel bed;
- a light source;
- and
- a screen having a partially reflective front surface disposed behind the simulated fuel bed for reflecting and transmitting light, and a back surface disposed behind the partially reflective front surface for transmitting light, the partially reflective front surface having a substantially non-reflective matte region, the non-reflective matte region being disposed distal from the simulated fuel bed, and the portion of the front surface not covered by the non-reflective matte region being a reflective region, such that the simulated fuel bed is substantially the only object reflected in the front surface, wherein light from the light source is transmitted through the front surface such that an image of flames appears through the front surface.

A simulated fireplace assembly having:
- a simulated fuel bed;
- a light source;
- a screen having a partially reflective front surface disposed behind the simulated fuel bed for reflecting and transmitting light, and a diffusing back surface disposed behind the partially reflective front surface for diffusing and transmitting light;
- a flicker element positioned in a path of light transmitted from the light source to the diffusing back surface;
- and
- the partially reflective front surface having a substantially non-reflective matte region, the non-reflective matte region being disposed distal from the simulated fuel bed, and the portion of the front surface not covered by the non-reflective matte region being a reflective region, such that the simulated fuel bed is substantially the only object reflected in the front surface, wherein light from the light source is transmitted through the front surface such that an image of flames appears through the front surface.
