Abstract: A flame simulating assembly is provided with a reflected flickering light that includes only one light source. Light from the light source passes through a rotating flicker element onto one or more reflectors, or mirrors, that reflect light up onto a simulated fuel bed and the some of the light is reflected off of the flicker elements towards a flame screen to create a simulated flame. The dipping flicker elements creates a fluttering light effect due to the flicker elements “intermittently dipping” into the light path. This fluctuating light is reflected onto the logs and ember bed in front and creates a dancing effect, which simulates glowing embers.

Abstract: A streamer type flame simulation device includes a casing, some cross-flow fans disposed inside the casing, a first streamer, a second streamer, a supplementary air-supplying device and a light source. The supplementary air-supplying device is arranged in the split joint area between the two cross-flow fans. Since a supplementary air-supplying device is provided between two cross-flow fans for supplying air, the deficiency where air was unable to deliver at the space occupied by the drive motor of the cross-flow fans can be avoided. Various parts of the first streamer and the second streamer can be blown, thus preventing the flame from being cut off and enhancing the overall coordination, which greatly improves the viewing effect of the flame area.

Beneficially, the electrically operated fireplaces disclosed herein do not require the use of moving parts, such as a rotating mirror, to provide the images of the flames. Further, since video images are used to provide the flame effect, the flame effect may be varied simply by loading a new video image into the memory portion of the control circuitry used to provide the flame display.

This fluctuating light is reflected onto the logs and ember bed in front and creates a dancing effect, which simulates glowing embers.

Abstract: A flame simulating device has a light source which is reflected by a rotating device which has mirrors which are spaced apart. The spaced apart mirrors rotate, and thus provide a selective reflection, at some points reflecting during time and at other points not reflecting during time. This produces a flickering effect. The flickering effect is shown through a cut out in the shape of the flame, to display a simulated flame devi effect. The display screen for the simulated effect can be a part mirror, and can display, for example, an artificial log mixed in with the flame effect.
