DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS
FIGS. 1 and 3f illustrate decorative light 10 according to an example embodiment. FIG. 1 illustrates decorative light 10 provided as part of a light string 12. FIG. 1 illustrates decorative light 10 separated from electrical string or cord 13. FIG. 3f illustrates portion of decorative light 10 in section for purposes of illustration. As shown by FIGS. 1 and 3f, decorative light 10 includes light bulb 14 and soft or flexible and at least partially translucent outer coating 16. Bulb 14 includes a head portion 18 surrounding an origin of light, such as a filament 21 (shown in FIG. 4), and a connection portion 20 configured to be connected to an electrical power source. In one embodiment, bulb 14 comprises an incandescent light bulb. In other embodiments, bulb 14 may comprise other light emitting devices, such as one or more light emitting diodes. In the example embodiment illustrated, connection portion 20 is configured to be screwed into a socket 22 of electrical cord 13. In other embodiments, connection portion 20 may comprise other electrical connecting and transmitting structures.
Coating 16 comprises multiple layers of distinct soft flexible and translucent materials extending about or around head portion 18 of bulb 14. In the particular example embodiment illustrated, coating 16 includes a first layer 24 of a translucent silicone material and a second layer 26 of a second translucent silicone material. In one embodiment, layers 24 and 26 have distinct colors. According to one example embodiment, coding 16 has an underlying layer of a darker color and overlying or outer layer of a lighter color. As a result, more light is able to pass through a multilayer coating 16. In another embodiment, layers 2426 may additionally or alternatively have distinct scents.
As shown by FIG. 3f, an exterior surface of coating 16 has formed therein grooves, waves or channels 30 that encircle head portion 18. According to one example embodiment, coating 16 has a single channel 30 that spirals about that portion 18. In other embodiments, coating 16 may be provided with a greater number of individual channels 30. In lieu of spiraling or twisting about head portion 18, such channels may alternatively concentrically extend about head portion 18. In other embodiments, grooves 30 may be replaced with other depressions, such as dimples or craters.
In the particular example illustrated, channel 30 has a varying depth. In the example illustrated, channel 30 includes channel portions 32A, 32B and 32C. Channel portions 32A extends substantially through layers 24 and 26 into close proximity to that portion 18 of bulb 14. As a result, light emitted through floors of channel portions 32A is substantially the same color as the color of light emitted by bulb 14. For example, if bulb 14 is a white light, white light is transmitted though channel portions 32A. Channel portions 32B extend substantially through layer 26 by do not extend through layer 24. Channel portions 32B extend into close proximity with an exterior of layer 24. As a result, light passing through floors of channel portions 32B will have a color determined by or controlled by the color of light emitted by bulb 14 as modified by the color of layer 24. Channel portions 32C extend only partially into layer 26. As a result, light emitted through the floors of channel portions 32C will have a color determined by or controlled by the color of light emitted by bulb 14, as modified by the collar of layer 24 and is further modified by the color of layer 26. The extent to which channel portions 32C extend into layer 26 (how close the floors of such channel portion 32C extend to layer 24) may also be varied to vary the extent to which layer 26 modifies (by selectively absorbing selected wavelengths of light) the color emitted through such channel portion 32C. In yet other embodiments, channel 30 may have a uniform depth across and through layers 24 and 26 of coating 16. Although coating 16 is illustrated as two such layers, in other embodiments, coating 16 may have a greater number of layers with one or more of the layers having distinct colors and/or scents.
FIGS. 2a-2f illustrate one example method for forming decorative light 10. As shown by FIGS. 2a and 2b, bulb 14 is initially dipped into a liquid or fluid silicone material 40 and withdrawn to form layer 24 upon head portion 18. Connection portion 20 of bulb 14 is not dipped into silicone material 40. Thereafter, the silicone coating 24 is permitted to solidify or cure.
As shown FIGS. 2c and 2d, bulb 14 with layer 24 is dipped into a liquid or fluid silicone material 44 and withdrawn. Silicone material 44 is distinct from silicone material 40. In one embodiment, material 44 has a distinct color or pigment as compared to silicone material 40. In another embodiment, silicone material 44 additionally or alternatively has a distinct scent as compared to silicone material 40. As shown by FIG. 2d, the withdrawn bulb 40 has two layers 24 and 26 which form coating 16. Although not shown in FIGS. 2a-2f, bulb 14 is withdrawn from the silicone material 44 so as to form an elongate substantially pointed tail 47 as shown FIG. 1. This tail 47 permits decorative light 10 to imitate or resemble a lit flame of a candle. In other embodiments, this tail may be omitted.
Although layers 24 and 26 are illustrated as being formed upon head portion 18 of bulb 14 by dipping bulb 14 into silicone materials 40 and 44, in other embodiments, layers 24 and 26 may be formed upon head portion 18 in other manners. For example, layers 24 and 26 may alternatively be sprayed, brushed, laminated or otherwise coated or applied to bulb 14.
As shown by FIG. 2e, groove 30 is formed by selectively removing portions of coating 16. In one embodiment, portions of layer 26 are removed prior to the silicone material of layer 26 solidifying or curing. Such portions of layer 26 are removed to expose layer 24 or lessen the thickness of layer 26. In the example illustrated, one or both of bulb 14 or a removal tool 50 having a removal edge 52 are rotated relative to one another while edge 52 is in contact and partially extending into layer 26 so as to form groove 30 extending about head portion 18. In the example embodiment illustrated, one or both of bulb 14 and removal tool 50 are further moved relative to one another along an axis 54 during such rotation such that groove 30 spirals or twists about axis 54 and about head portion 18 of bulb 14 in the direction indicated by arrow 55.
In those embodiments in which channel 30 penetrates at least partially into layer 24, other removal techniques may be employed to remove the already cured or solidified portions of layer 24. For example, a relatively sharp knife or blade may be used to remove portions of layer 26 as well as the cured or solidified portions of layer 24. In yet other embodiments, layer 26 may be formed upon layer 24 prior to complete curing or solidification of layer 24. In such an embodiment, portions of layer 24 may also be removed prior to complete curing or solidification of layer 24, easing the amount of force or the aggressiveness of the removal technique for removing selected portions of layer 24. In still other embodiments, only portions of layer 26 may be removed to form channel 30. After groove 30 is informed, layer 26 is permitted to solidify or to cure.
FIG. 3 illustrates a larger portion of light string 12 (shown also in FIG. 1). FIG. 3 illustrates decorative light 10 connected to electrical cord 13. FIG. 3 further illustrates decorative lights 110 and 210 also connected to electrical cord 13 to form light string 12. In the particular example illustrated, light 10 has a first silicone layer 24 provided with a red pigment or tone and a second silicone layer 26 formed from a silicone material having a white pigment or tone. At the same time, bulb 14 is configured to emit light having a reddish or orange color or pigment, rather than white light. As a result, those portions of layer 24 which have a higher degree of exposure remain red such that the resulting light passing through grooves 30, which expose portions of layer 24, has a red color rather than a pink color. Consequently, colors of light passing through coating 16 remain distinct from one another, resulting in light 10 providing red and white stripes. By selectively emitting a non-white light with bulb 14 chosen based upon the particular color combinations of coating 16, three of more distinct colors of light may be provided or the distinctiveness or two or more colors of light emitted from light 10 may be maintained.
Light 110 and 210 are similar to light 10 expect that lights 110 and 210 have distinct combinations of silicone. According to one embodiment, light 110 has an underlying layer 124 provide with an orange pigment or color and an overlying layer 126 provided with a black pigment or color. Light 210 is similar to light 10 expect that light 210 alternatively include a first layer 224 which is provided with a while pigment or color in a first sent while layer 226 is provided with a red color or pigment and a second distinct scent. In other embodiments, light string 12 may have other decorative light having other combinations of colors and/or scents. In one embodiment, light string 12 may be provided with all of one type of decorative light, each light having the same combination of colors and/or scents. In another embodiment different record of lights having different combinations of colors and/or scents may be combined as shown in FIG. 3. Other examples of color combination include (the first color being the underlying color): violet/white, dark purple/white, royal blue/white, light blue/white, Sage/white, tan/white, cinnamon brown/white, green/brown and green/orange.
FIG. 4 illustrates decorative light 310, another embodiment of the decorative light 10. Portions of light 310 are shown in section for purpose of illustration. Decorative light 310 is similar to decorative light 10 except that decorative light 310 includes coating 316 having layers 324 and 326 in lieu of layers 24 and 26, respectively. Those remaining elements of light 310 which correspond to elements of light 10 are numbered similarly.
Layers 324 and 326 similar to layers 24 and 26 accept that layers 324 and 326 additionally include embedded particulates, granules, crystals, flakes, bubbles or embedded objects and the like (collectively referred to as embeds 327, which are schematically illustrated) dispersed throughout layers 324 and 326. In one embodiment, layer 324 may have a first embed dispersed throughout while layer 326 has a second embed dispersed throughout. In other embodiments, layer 324 and 326 may have the same embeds dispersed throughout. Examples of embeds include dried flowers, coffee grains, seeds, glitter, hazelnut coffee grains or crystals commercially available under the brand FOLGERS. In one embodiment, materials 22 comprise poppy seeds. In yet other embodiments, embeds 327 may comprise a whole, ground or cut materials such as seeds, spices, or ground plant or flower parts. In other embodiments, and then throughout 327 may comprise granules or flakes visible through material of layer or 324 or layer 326. In other embodiments, embeds 327 may comprise phosphors, which upon being excited, such as upon receiving ultraviolet light or radiation from bulb 14 (wherein bulb 14 is configured to emit radiation, such as alter file at light), emit visible light. Embeds 327 are generally provided by mixing such embeds 327 in one or more materials of layer 324 or 326 while the one or more materials of layer 324 or 326 are in a fluid state. For example, in embodiments where layer 324 is formed from silicone, embeds into 327 are mixed and distributed throughout the silicone or prior to the silicone being cured and while the silicone is in a fluid state. Upon curing or solidifying, the flexible material of body 20 fixes particulate material 22 throughout the matrix of material provided by the material of layer 324.
Embeds 327 including embedded objects comprise miniature objects having shapes corresponding to full-sized objects and formed from plastic, wood, metal or other materials. In one embodiment such embedded may have shapes corresponding to holidays such as hearts, stars, shamrocks, crosses, eggs, pumpkins, witches and the like. And one embodiment, embeds number 327 comprising objects may be colored or may have multiple colors associated with a particular holiday or event. In one embodiment, embed objects 327 may comprise one or more alphanumeric symbols or words.
Embeds 327 including bubbles comprise pockets or cavities of air or other gas dispersed or distributed throughout the material layer 324 or layer 326. Such embeds 327 may visually alter light or other electromagnetic radiation being transmitted through a material of layers 324 or layer 326 or being reflected or emanating from the other embeds 327. In particular embodiments, embeds comprising bubbles may be uniformly distributed throughout body layer 324 or layer 326. In other embodiments, such bubble embeds may be non-uniformly distributed within the layers. According to one embodiment, bubble embeds are formed by injecting air or other gas into the material of layer 324 or layer 326 prior to the material of layer 324 or layer 326 solidifying, curing or hardening. In particular embodiments, bubble embeds may alternatively be formed by the addition of a gassing agent to the one or more materials of layer 324 or layer 326.
