Flames have a specific form that changes over time in a stochastic way.
Artificial flames can be visually pleasing.
An embodiment describes a device that produces a three dimensional simulation view of a flame. In one embodiment, the device can be a display device, e.g., a display style fireplace.
The device has a light source, a reflector and an image screen on which the flame is viewed. The reflector has a motor, forming a rotating axis, rotating surface and reflecting elements. The reflecting elements can be blades that move or can be other kinds of reflecting pieces. The motor rotates to form a rotating axis between the motor and the image screen. The rotating surface is fixed on the rotating axis and rotates to change the reflection that is formed.
The rotating surface has some intermittent reflecting pieces, intermixed with non reflecting parts. The light from the light source is reflected onto the image screen by the reflecting pieces as the rotating surface is rotated, thereby producing realistic flickering flames.
In the Drawings:
The figures show aspects of the invention.
An embodiment is shown in
The reflector 2 has a motor 21, which rotates a rotating surface 23 around a rotating axis 22. The rotating surface 23 is further shown in
In an embodiment, the reflecting elements 24 are steel reflecting blades, or mirrors, or any other material that reflects. By rotating the reflecting elements between the light source 1 and screen, the light from the light source 1 will be selectively reflected onto the image screen 3 by the reflecting elements 24 as they pass between the light source 1 and the screen 3. That is, as the rotating surface rotates around the rotating axis 24 based on rotation of the motor, the light will be selectively reflected by the reflecting elements 24, and either not reflected or less reflected by the areas between the adjacent reflecting elements 24. The reflecting elements 24 are spread around the axis in a fan-shape where different portions of the circular sectors have reflecting elements, and other portions of the circular sectors do not have those reflecting elements.
The rotating shaft 22 is attached to the motor 21 to rotate when driven by based on rotation by the motor. In one embodiment, the rotating shaft is fixed on the motor 21 The rotating shaft 22 forms a rotating axis that carries out the selective reflection between the light source 1 and the image screen 3.
A support stand 5 holds the motor 21 at an angle set by the stand 5. The stand 5 can be adjusted for different angles and will allow the rotating axis 22 to face in different directions to rotate at different angles: up and down, left and right.
The image screen 3 is made of semi-transparent or diffusing material. The semitransparent material can be materials such as ABS material. The screen 3 has an illumination side 120 that faces toward the reflector 2 and the flame shaped board 4, and receives the light that is reflected by the reflector elements 24. The screen 3 also has a viewing side 130 not facing the reflector 2 and the flame shaped board, and that allows viewing the flame effect. In one embodiment, this can allow viewing colorful flames to be shown from the viewing side 130 of the image screen 3.
In an alternative embodiment, the viewing side 130 of the image screen 3 includes the viewing side 130 being silver plated to form either a full mirror or a semi-transparent mirror. The semi-transparent mirror reflects the object in its front and allows light from the back to be seen through to its front.
In an embodiment where the image screen includes a full or partial mirror, artificial burning elements 6 such as an artificial log can be provided. These are also reflected and the reflection is also shown in the mirror, causing a visual doubling of the artificial log, to allow the front of the log to be seen directly, and also the reflection to be seen as a doubled view, as shown in
The mirror can also be used to simulate a 3D effect to the flame.
In an embodiment, the light source 1 is plural LEDs illuminating against the rotating axis 22.
In another embodiment, the multiple LEDs of the light source can be of different colors to produce colorful flames.
In another embodiment, side reflectors that are vertically disposed relative to the reflecting elements 24. These side reflectors can project flame light onto a side flame screen, e.g. left or right. This allows this embodiment to create simulated flames all of in front and in left or right side at the same time.
