20100205838Electric Fireplace Flame Curtain with Fixed Simulated Carbon Bed - The invention relates to an electric fireplace flame curtain with fixed simulated charcoal bed comprises a transparent plate, a imaging mechanism and a charcoal bed being disposed on the transparent plate, and a number of fixed light-holding charcoals with plurality of transparent surfaces being disposed on the charcoal bed. The charcoal bed is fixed directly on the transparent plate with imaging mechanism, so the image of charcoal flame after optimization appears on the image screen, which has the best visual effect. The essential effect of the present invention is to solve the monotone flame and poor visual effect of the exiting electric fireplace. Meanwhile, the problems such as constant charcoal flame brightness, lack of reality are solved as well. The present invention could simulate a plurality of independent charcoal burning spots, with various styles. The light-spots of the flame are sparkling intermittently with bright and shade, and the flame is of light-holding effect. The visual effect and the authenticity are both perfect.08-19-2010
20100205839Electric Fireplace with Flame Curtain - The invention relates to a An electric fireplace with a flame curtain comprises a housing, a light source, a flame curtain with integral structure being disposed on the electric fireplace and in front of an electric fireplace flame generator, an imaging mechanism and a charcoal bed being disposed on the flame curtain, and a number of light-holding charcoal with a plurality of transparent surfaces being disposed on the charcoal bed. The essential effect of the present invention is to solve the problems of constant charcoal flame brightness, the lacking of reality and the bad charcoal flame simulation effect in conventional electric fireplaces. Meanwhile, the problems of constant charcoal flame shape, dull appearance and poor visual effect in conventional electric fireplace are solved as well. The present invention is of simple structure and easy assembly process, while the charcoal flame structure can be arbitrarily changed, the light-spots of the flame are sparkling intermittently with bright and shade, and the flame is of light-holding effect. The visual effect and the authenticity are both perfect.08-19-2010
20100205840Electric Fireplace Flame Curtain with Flexible Simulated Carbon Bed - The present invention relates to an electric fireplace flame curtain with flexible simulated charcoal bed, the flame curtain is a structure of vessel, comprises a front wall and a rear wall with transparent structure, an imaging mechanism disposed on the front wall of the vessel, a number of movable light-holding charcoals with a plurality of transparent surfaces disposed in the vessel. The essential effect of the present invention is to solve the monotone flame, dull appearance and poor visual effect of the exiting electric fireplace. Meanwhile, the problems such as constant charcoal flame brightness, lack of reality, bad simulative effect are solved as well. The present invention could simulate a plurality of independent charcoal burning spots, with various styles. The light-spots of the flame are sparkling intermittently with bright and shade, and the flame is of light-holding effect. The visual effect and the authenticity are both perfect.08-19-2010
201002098603D Flexible Simulated Carbon Bed and Electric Fireplace with 3D Flexible Simulated Carbon Bed - The present invention relates to a stereo flexible charcoal bed and an electric fireplace with a flexible charcoal bed comprising a vessel with at least one transparent bottom, a number of charcoals disposed in the vessel comprising a number of movable light-holding charcoals with a plurality of transparent surfaces, an imaging mechanism disposed on the charcoals. The essential effect of the present invention is to solve the monotone charcoal flame, bad sense of stereo and poor visual effect of the exiting electric fireplace, meanwhile, the problems such as bad simulative effect, and lack of reality and the sense of stereo are solved as well. The charcoal flame structure of the present invention could change arbitrarily and the light-spots of burning flame are sparkling intermittently with bright and shade. The visual effect and the authenticity are both perfect.08-19-2010

20100172636Three-Dimensional Flame Simulating Electric Fireplace - The present invention relates to an electric fireplace having a 3D flame simulating assembly, which comprises housing, an imaging light source, a light processing unit and a simulated charcoal disposed in front of the inner cavity of said housing. A translucent imaging screen is positioned against the back of the simulated charcoal and a second translucent imaging screen is positioned just in front of and parallel to the translucent imaging screen. The light emitted from the imaging light source is projected onto the imaging screen to form a primary simulated flame image after passing through the light processing unit, and portion of which is further projected onto the second imaging screen to form a secondary simulated flame image after passing through the image screen. If the distance between the imaging screen and the second imaging screen is kept to be enough, a visual effect of rising and leaping simulated flames with spatial depth is generated due to the different front to back positions of the flame images imaged on both screens.07-08-2010
