DETAILED DESCRIPTION
[0056] The following discussion provides example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.
[0057] The inventor has discovered that electronic lighting devices can be produced using various designs without reducing the ability to simulate a real candle light. Specifically, the flame element can be suspended using a variety of means without sacrificing the ability to mimic a real candle light. For example, the flame element can be mounted on an arm of the housing. In another example, the flame element can have a clip configured to couple with a mounting rod. Indeed, it should be appreciated that the support structures for suspending flame element are hidden, such that they are not readily visible to users and do not cast a shadow on the flame element by light emitted from a light source of the electronic lighting device. Thus, various electronic lighting devices are disclosed that mimic a real candle light.
[0058] In
[0059] Outer shell 103 can have a scented or unscented wax coating and an uneven top ridge 102, as shown in
[0060] In yet another example, 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.
[0061]
[0062] It is contemplated that a projection 117 of flame element 101 rests within a recessed area of arm 115 to suspend 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.
[0063] Electronic lighting device 100 can further comprise a light source 123 and a lens 124. Light source 123 can be an LED or another light source sufficient to emit light onto flame element 101. Lens 124 can be used can be used to focus light emitted from light source 123. It is contemplated that a light controlling material (e.g., tape or other thin layer or other commercially suitable material) can be disposed on at least one an inner surface of housing 105, an outer surface of housing 105, and the perimeter of the housing for light source 123 and lens 124. Such light controlling material can prevent light from bleeding through the sides of the housing, which can reduce the ability of electronic lighting device 100 to mimic a real candle.
[0064] 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 0-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 0-ring 122 can be disposed in other areas of flame element 101 or that more than one 0-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.
[0065]
[0066] It is contemplated that 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. By forming housing 205 as a single piece, the number of parts is reduced, simplifying assembly (e.g., by robotic or human assembly lines).
[0067] Electronic lighting device 200 further includes a mounting bracket 219 as shown in
[0068] 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.
[0069] Mounting bracket 219 is inserted upwardly through the bottom opening of housing 205. It is contemplated that mounting bracket 219 can be coupled to housing 205 by a variety of coupling techniques (e.g., glue, epoxy, snap-fit, pressure-fit, lock-fit, rotational lock-fitting, rotational snap-fitting, using fasteners such as screws, nuts, bolts, and/or washers), or it can be secured by another piece or pieces dedicated to holding mounting bracket 219 in housing 205. Thus, it should be appreciated that housing 205 is sized and dimensioned to receive mounting bracket 219 in an internal cavity 213 as shown in
[0070] Flame element 201 has an aperture 209 and a hollow interior 207. Housing 205 has an arm 215 that can extend into hollow interior 207, such that a projection 217 of flame element 201 rests on a recessed area of arm 215 to suspend flame element 201 in housing 205. 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. Alternatively, it is contemplated that flame element 201 has a horizontally extended channel that receives arm 215, wherein the remainder of flame element 201 is solid. Once flame element 201 is suspended on arm 215, light may be emitted from light source 223 while flame element 201 moves to simulate a moving flame. It should be appreciated that tab 229 reduces the risk of flame element 201 falling or separating from arm 215 while flame element 201 is moving to simulate a real candle light.
[0071] An exemplary flame element 301 is shown in
[0072] Tab 329 can be defined by a sidewall 311 of flame element 301. Furthermore, tab 329 can define a portion of an aperture 309 of flame element 301. Typically, tab 329 is a flexible material, such that an arm of a housing can bend tab 329 in an amount sufficient to allow the arm to enter hollow interior 307 of flame element 301 and suspend flame element 301.
[0073] As discussed above, flame element 301 can have a projection 317. Projection 317 is typically disposed in hollow interior 307. While projection 317 is shown as a cone shape, it is contemplated that other shapes are suitable, such as a sphere, a cone with a flat top, a cylinder, a cube, a rectangle, a prism, and any other shape that is would allow flame element 301 to move in a manner that simulates a real candle light while suspended in a housing.
[0074] Flame element 301 is preferably predominantly white in color, though different colors are contemplated, as well as different transparencies. Though only the flame element is explicitly described as an example, color or transparency variations discussed herein can alternatively apply to only a portion of the flame element 301. Preferably, flame-shaped portion 325 can have various colors and transparencies, but body portion 327 may also be made to have different colors or transparencies. Ideally, the flame element 301 is colored such that light projected onto it is reflected so that it is visible to a human observer. Variations of the color white or other colors (e.g., red, orange, yellow, blue, and any combination thereof, including gradient changes from one color to another and/or color blends) can be used depending on the color of light that is to be reflected. Additionally, the flame element 301 can comprise different materials or finishes depending on the desired effect. A glossy finish may be desirable in some circumstances, while in others a matte finish may be desired. The finish of the flame element material can affect how light is reflected by the flame element 301, where matte finishes would reflect the light in more directions than a glossy finish.
[0075] The thickness of the material can also affect optical qualities. For example, the thickness flame-shaped portion 325 can affect the amount of light that is able to pass through flame-shaped portion 325 by diffusion. In addition, flame-shaped portion 325 can be made from one or more materials which have varying levels of transparency, ranging from completely transparent to completely opaque. For example, in some embodiments, flame-shaped portion 325 can allow more than 50% of incident light to pass through, while other embodiments can restrict light passage to 40% of incident light, 30% of incident light, 20% of incident light, 10% of incident light, or 0% of incident light (meaning the material is substantially opaque). Some embodiments can have different transparencies in different portions flame-shaped portion 325. For example, one embodiment might be more transparent near the top of flame-shaped portion 325 and have a gradient whereby transparency at each point moving toward body portion 327 is decreased. These effects are important for devices where light is projected onto one side of the flame element 301, but is also to be viewed on the opposite side as the light passes through.
[0076] Some embodiments of the flame element 301 can include light transmitting channels that allow light to be shined onto an area of the flame element 301 such that the light can then be seen from a different area of the flame element 301. For example, if light is shined onto body portion 327 it will then be visible from flame-shaped portion 325 of flame element 301 via the light channel. Alternatively to light channels, the flame element 301 can be made from composite materials having desirable optical qualities to produce a similar result (e.g., flame element 301 can have a core and an outer coating, where the core is made from a material that is substantially transparent such that light can pass through it and the outer coating made from a material that is substantially translucent such that light is more effectively transmitted throughout the entire flame element 301).
[0077] In some embodiments, flame element 301 comprises a second aperture 331 as shown in
[0078]
[0079] An exemplary housing 405 is shown in
[0080] It is contemplated that some embodiments can further include a pin to provide additional stability of the flame element on the arm of the housing. For example,
[0081] Arm 515 extends into flame element 501 and has a recess 535, as shown in
[0082] As discussed above, electronic lighting devices can have a flame element with a projection that extends into the hollow interior and the projection rests on an arm of the housing. However, it is contemplated that a flame element 601 has a body portion 627 with a convex apex 643 that defines an upper portion of hollow interior 607 as shown in
[0083] It should be appreciated that tab 629 provides additional support for flame element 601 to remain on arm 615 while flame element 601 is moving to simulate a real candle light. As shown in
[0084] While an arm can be used to suspend a flame element in a housing, it is contemplated that other suitable components can be used to suspend the flame element without sacrificing the ability to simulate a real candle light. For example,
[0085] Flame element 701 is at least partially disposed within housing 705 and wire clip 747 is disposed on flame element 701. Mounting rod 749 is sized and dimensioned to couple flame element 701 by engaging wire clip 747 so as to allow movement of flame element 701 with respect to housing 705 while flame element 701 is coupled to housing 705.
[0086]
[0087] Flame element 701 has a flame-shaped portion 725 and a body portion 727 as shown in
[0088] While a wire clip can be used to suspend the flame element, it is contemplated that an electronic lighting device 800 comprises an arch 853 disposed on a flame element 801 as shown in
[0089] Electronic lighting device 800 further comprises a mounting bracket 819, which has a slot 851 and can receive a light source 823 as shown in
[0090]
[0091] Another electronic lighting device having a flame element with a clip is illustrated in
[0092]
[0093]
[0094] It should be appreciated that the clips described above can be disposed on an exterior surface of the flame element. For example, the clip can be disposed on at least one of the flame-shaped portion and the body portion of the flame element. Thus, the clip supports the flame element, and eliminates the need for an aperture on the flame element and a support wire that extends through the aperture to support the flame element in the housing.
[0095] While clips as discussed above can be used to suspend a flame element to allow movement that simulates a real candle light, it is further contemplated that a support wire can also suspend a flame element. For example,
[0096]
[0097] Support wire 1061 is preferably coupled to a mounting bracket 1019, although in some embodiments may be alternatively mounted to housing 1005. Additionally, support wire 1061 can be coupled to mounting bracket 1019 or housing 1005 in a number of ways. For example, in some embodiments the ends of the support wire 1061 can be fitted into grooves in mounting bracket 1019 or housing 1005. In other embodiments, the support wire 1061 can be glued to mounting bracket 1019 or housing 1005, while in still other embodiments it is fastened into place by a fastening technique (e.g., screw, adhesive, pressure fit, having the ends of the support wire fit within receiving holes, or even material deformation of the support wire 1061 to couple it to mounting bracket 1019 or housing 1005). It is contemplated that housing 1005 has a bottom surface that overlaps slit 1063 when housing 1005 receives mounting bracket 1019, such that support wire 1061 is at least partly secured in slit 1063 by housing 1005.
[0098] Mounting bracket 1019 can further include a light source 1023 that is configured to emit light onto flame element 1001. Light source 1023 can rest within a groove 1021 of mounting bracket 1019. However, it is also contemplated that housing 1005 can have a groove configured to receive light source 1023. Nonetheless, it should be appreciated that support wire 1061 is positioned in a manner (e.g., positioned below light emitted from light source 1023, positioned to extend perpendicular to light source 1023, etc.) that does not block light emitted from light source 1023. In other words, support wire 1061 does not cast a shadow on flame element 1001 from light emitted from light source 1023. In other words, support wire 1061 is most typically hidden behind a front of flame element 1001 define by a face 1067.
[0099] Flame element 1001 has a flame-shaped portion 1025 and a body portion 1027 as shown in
[0100] It is contemplated that flame element 1001 can have flame-shaped portion 1025 with a first weight and body portion 1027 with a second weight, such that the second weight is greater than the first weight. Typically, the center of mass of flame element 1001 is below aperture 1065, which ensures that flame element 1001 remains upright when it is supported in housing 1005. Additionally, or alternatively, body portion 1027 comprises elongated portion 1071 and base portion 1073, and elongated portion 1071 has a smaller cross-sectional are than base portion 1073.
[0101] As discussed above, various different configurations are contemplated for electronic lighting devices. One of the various contemplated configurations comprises an electronic lighting device 1100 having an arm 1115 that is removably coupled to housing 1105 as shown in
[0102]
[0103] As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0104] Also, as used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
[0105] In some embodiments, the numbers expressing quantities of ingredients, properties such as concentration, reaction conditions, and so forth, used to describe and claim certain embodiments of the invention are to be understood as being modified in some instances by the term “about.” Accordingly, in some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, and unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints and open-ended ranges should be interpreted to include only commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary.
[0106] Thus, it should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the disclosure. Moreover, in interpreting the disclosure all terms should be interpreted in the broadest possible manner consistent with the context. In particular the terms “comprises” and “comprising” should be interpreted as referring to the elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps can be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced.
