For example, Fig. 1C shows a cross-sectional view of electronic lighting device 100 where a circuit board 104 and flame element 101 is at least partially disposed within outer shell 103. Another contemplated part disposed within outer shell 103 is a light controlling material, such as an opaque layer, which reduces or prevents light from bleeding through all or a portion of the outer shell 103.

The thin layer can also be disposed around the perimeter of a light source within electronic lighting device 100 to reduce light from being emitted through the sides of the light source. In such embodiments, it is contemplated that an opaque tape or other material could be wrapped about a portion of the light source to prevent light from emanating in certain directions.
  • electronic lighting device 100 can include an opaque interior chassis in at least a portion of electronic lighting device 100. It should be appreciated that these light controlling materials will enhance the simulation of electronic lighting device 100 to mimic a real candle by limiting light emitted from electronic lighting device 100 to the top as seen in various real candles.
  • Fig. 1D shows an enlarged view of the upper region of electronic lighting device 100.
  • Electronic lighting device 100 comprises flame element 101 and housing 105.
  • Flame element 101 has a hollow interior 107 and an aperture 109 disposed on a side 111 of flame element 101.

Additionally, or alternatively, it is contemplated that a tab 129 disposed on a side 111 of flame element 101 reduces the risk of flame element 101 falling or separating from arm 115. This reduction in risk is at least due to tab 129 and a downward projection 137 of arm 115 overlapping, such that the height of aperture 109 is less than a height of arm 115 as measured from the top surface of arm 115 to the apex of projection 137. Thus, it is contemplated that tab 129 can be required to move to allow insertion of removal of flame element 101 from arm 115.

  • Flame element 101 can further include an O-ring 122 that is disposed in a channel near the bottom surface of flame element 101. It is contemplated that O-ring 122 is used to reduce the noise generated when flame element 101 bumps into housing 105 while flame element 101 is moving to simulate a moving flame. While O-ring 122 is disposed near the bottom of flame element 101, it is contemplated that O-ring 122 can be disposed in other areas of flame element 101 or that more than one O-ring 122 is disposed on flame element 101 so long as it is suitable to reduce the noise generated when flame element 101 bumps housing 105.

  • Figure 2B shows a side view of electronic lighting device 200. Housing 205 has an upper region with a top opening 269 that has a smaller circumference than a bottom region that has a bottom opening with a larger circumference.
  • flame element 201 is suspended to extend through top opening 269 near one end ( e.g., front end or back end) of top opening 269. In other words, flame element 201 is not suspended to extend through the center of top opening 269. However, in other contemplated embodiments, flame element 201 is suspended to extend through the center of top opening 269.
  • housing 205 can be manufactured as a single piece via injection molding. By creating housing 205 as a single piece, the overall complexity of the device is significantly reduced.

  • a light controlling material can be disposed on at least one of an internal surface of groove 221, an internal surface of housing 205, and an external surface of housing 205.
  • Light source 223 can project different colors of light, though preferably it projects a color that is similar to the color of a candle flame (e.g., orange, yellow, red, blue, or some combination thereof).
  • a lens 224 is used to focus the light to a desired degree. For example, a focal length greater than the distance between the lens 224 and the flame element 201 can provide softer lighting than if the light were focused directly onto the flame element. Alternatively, the focal length can be shorter than the distance between the lens 224 and the flame element 201 to achieve substantially the same effect since with a simple lighting device (e.g., an LED) the orientation of the image is irrelevant.

While this embodiment shows that arm 215 extends from housing 205, it is contemplated that arm 215 can extend from mounting bracket 219 to suspend flame element 201 within housing 205.
  • flame element 201 has a horizontally extended channel that receives arm 215, wherein the remainder of flame element 201 is solid.
