Definitions

  • Flameless candles may provide an illusion of a real (flamed) candle, but without the risk of fire damage.
  • a real candle flame moves in physical space.
  • Moving parts may be undesirable for various reasons. For example, moving parts may tend to become damaged, such as during shipping, by mishandling, or by unintentional events.
  • FIGS. 1-3B illustrate an electronic candle 100, according to techniques of the present application.
  • the electronic candle 100 may include a side wall 102 having an upper region and a lower region.
  • a base 150 (see FIG. 2 ) may be engaged with the lower region of the side wall 102.
  • An upper surface 106 may extend from the upper region of the sidewall 102 to form an upper recess 104.
  • the upper recess 104 may have a variety of different shapes.
  • the upper recess 104 may be shaped like a bowl or a portion of a bowl.
  • the upper region of the side wall 102 may have a varying height around the top perimeter of the electronic candle 100.
  • the upper recess 104 may have a rounded or flat bottom surface.
  • the upper recess 104 may have a smooth or textured bottom surface.
  • the upper recess 104 may have a cylindrical shape.
  • the projection screen 110 may extend upwardly from the riser 140.
  • the projection screen 110 may be rigidly affixed to the riser 140 at or near the top of the riser 140.
  • the projection screen 110 may be integral with the riser 140.
  • the projection screen 110 may be a separate portion rigidly attached to the riser 140 (for example, glued or attached at more than one place).
  • By rigidly affixing the projection screen 110 with the riser 140 it may be possible to fix the position of the projection screen 110 with respect to the upper surface 106.
  • the projection screen 110 may be affixed to the upper surface 106 or to the sidewall 102 instead of the riser 140.
  • the surface of the projection screen 110 may be flat, concave, or convex.
  • the surface of the projection screen 110 may be various combinations of flat, concave, and/or convex.
  • the projection screen 110 may have a two-dimensional or three-dimensional appearance.
  • the projection screen 110 may have a flame shape. Such a shape may be static, in that it does not change.
  • the projection screen 110 may have one or more projection surfaces.
  • the projection screen 110 may have two projection surfaces - front and back.
  • the projection screen 110 may have additional projection surfaces.
  • the projection screen 110 may have three or more surfaces, each receiving light from one or more sources of light.
  • the projection screen 110 may have surfaces that wrap around to form a shape with substantial depth.
  • the projection screen 110 may have a three-dimensional shape resembling an actual candle flame. In such an example, sources of light may be located around the projection screen 110 and may project onto the projection screen 110.
  • each source of light 120, 130 may project light (either completely or partially) through the aperture 108 in the upper surface 106 and onto the projection screen 110.
  • the light emitted from each source of light 120, 130 may radiate according to a beam width.
  • the beam widths for the light emitted from the sources of light 120, 130 may be between 30-35 degrees.
  • the beam axis for the light emitted from each of the sources of light may intersect with the primary plane of the projection screen 110. Such an intersection may have an angle between 20-40 degrees.
  • the sources of light 120, 130 may project light onto the same side or different sides of the projection screen 110.
  • the source of light 120 may project light onto the front side of the projection screen 110, while the source of light 130 may project light onto the back side of the projection screen 110. If the projection screen 110 is translucent, light projected onto one side may penetrate to the other side.
