Abstract
Abstract A flame simulating assembly for providing an image of flames transmitted in a fluctuating light. The flame simulating assembly has a simulated fuel bed, a light source, a screen disposed behind the simulated fuel bed for diffusing and transmitting light, and a flicker element for creating the fluctuating light, the flicker element being positioned in a path of light from the light source. The simulated fuel bed defines a profile viewable by an observer. In addition, the screen includes a curved portion which is curved in a vertical direction and in a horizontal direction to correspond to the profile of the simulated fuel bed. Also, the curved portion of the screen is positioned adjacent to the simulated fuel bed. The fluctuating light transmitted through the screen is attenuated and a three-dimensional image of flames appears to curve around the profile of the simulated fuel bed.
