Title: System for directional control of light and associated methods

Description:
FIELD OF THE INVENTION 
     The present invention relates to systems and methods for controlling the direction of emitted light. 
     BACKGROUND OF THE INVENTION 
     Directional lighting from a single lighting device has traditionally been limited to the positioning of an illuminant, such as a light-emitting diode (LED) to emit light in a selected direction. As nearly all LEDs emit light in the hemisphere directly above the LED (or below depending on the configuration of the LED), the directional control of light has typically been accomplished by positioning the LED such that an apex of the LED is pointed in the direction desired to be illuminated, and the use of optics to shape the beam of light emitted by the LED. This results in the need for multiple discrete structures capable of being positioned independently of one another in order to achieve multi-directional lighting from a single device. Additionally, this requires multiple discrete circuit boards upon which the LEDs are positioned, or circuit boards that are either flexible or contain bends, both of which are cumbersome to employ. This type of device has significant costs in terms of materials for each discrete structure and for enabling repositioning thereof. 
     Additionally, the use of light-piping materials has enabled the redirection of light emitted by an LED such that it is emitted at a relatively distant location in a direction other than the hemisphere above the LED. However, light-piping materials typically reduce the brightness of light conducted thereby such that it is not useful for illuminating purposes. Additionally, light-piping materials are traditionally used in a single LED device, and not utilized where there is an array of LEDs. 
     Accordingly, there is a need in the art for a lighting device capable of enabling multi-directional lighting that is suitable for illuminating purposes, while reducing the cost of production, namely, the cost of providing structural support for the lighting device, and reducing the number of circuit boards employed for enabling said directional illumination. 
     This background information is provided to reveal information believed by the applicant to be of possible relevance to the present invention. No admission is necessarily intended, nor should be construed, that any of the preceding information constitutes prior art against the present invention. 
     SUMMARY OF THE INVENTION 
     With the foregoing in mind, embodiments of the present invention are related to an optic for emitting light in selective directions. The optic may include a receiving section having a receiving surface, an intermediate section, and an emitting section comprising a plurality of facets. Each facet of the plurality of facets may be configured to be associated with a respective light source of a plurality of light sources. The receiving surface may be configured to direct light incident thereupon through the intermediate section to a facet of the emitting section. Each facet of the plurality of facets may be configured to redirect light received from the receiving surface. Additionally, substantially each facet of the plurality of facets may be configured to redirect light in a direction that is unique from the other facets of the plurality of facets. 
     In another embodiment of the invention, a lighting device for emitting light in selective directions may include a first light source structure member having an outer surface, a first plurality of light sources that may be attached to the outer surface of the light source structure member, a controller functionally coupled to the plurality of lighting devices, a power supply positioned in electrical communication with at least one of the controller and the first plurality of lighting devices, and a first optic.

The emitting section may comprise a plurality of facets. Furthermore, each light source of the second plurality of light sources may be positioned such that light emitted thereby is received by the receiving surface. The light may then be directed through the intermediate section and emitted through a facet of the plurality of facets of the second optic. Each facet of the plurality of facets of the second optic may be configured to redirect light in a direction that is unique from the other facets of the plurality of facets of the second optic. Additionally, the power supply may be positioned in electrical communication with at least one of the controller first plurality of light sources and the second plurality of light sources. Furthermore, the controller may be configured to selectively operate each light source of the first and second pluralities of light sources. The receiving surface of the first optic may define a first plane, and the receiving surface of the second optic may defend second plane. The first plane may be skew to the second plane. In some embodiments the first plane may be perpendicular to the second plane.

Additionally, the lighting device may further include a power supply positioned in electrical communication with at least one of the controller and the plurality of light sources of the plurality of lighting structures. 
     The plurality of lighting structures may be positioned such that the inner surface of each light source structure member cooperates to define an internal cavity. Additionally, each of the controller and the power supply may be carried by at least one light source structure member of the plurality of lighting structures such that the controller is positioned within the internal cavity. In some embodiments, each of the controller and the power supply may be carried by a structural support of the lighting device. Similarly, each of the lighting structures of the plurality of lighting structures may similarly be carried by the structural support. Furthermore, the controller may be configured to selectively operate each light source of the plurality of light sources of each lighting structure. Each light source of the plurality of light sources of each lighting structure may be positioned such that the light emitted thereby is received by the receiving surface of the same lighting structure, directed through the intermediate section, and emitted through a facet of the plurality of facets of the optic of the same lighting structure. Additionally, each facet of the plurality of facets of each lighting structure may be configured to redirect light in a direction unique from the other facets of the plurality of facets of the same lighting structure. Furthermore, in some embodiments, each facet of the plurality of facets of each lighting structure may be configured to redirect light in a direction unique from the other facets of the plurality of facets of each lighting structure.

     An embodiment of the invention, as shown and described by the various figures and accompanying text, provides an optic for a lighting device. Referring now to  FIG. 1 , an optic  100  according to an embodiment of the present invention will now be discussed in detail. The optic  100  may be configured to receive light from one or more light sources and redirect that incident light in multiple directions. The direction in which the incident light is redirected may be determined by where the light is incident on the optic  100 . 
     The optic  100  may include a receiving section  110 , an intermediate section  120 , and an emitting section  130 . The intermediate section  120  may be positioned between the receiving section  110  and the emitting section  130 . Each of the receiving section  110 , the intermediate section  120 , and the emitting section  130  may be formed of transparent or translucent material. Moreover, each may be formed of the same material, or a variety of materials may be used. In some embodiments, the optic  100  may be formed as a single integral structure. In other embodiments, one or more of the receiving section  110 , the intermediate section  120 , and the emitting section  130  may be formed apart from the other parts of the optic  100  and may be attached and placed in optical communication with the adjacent parts of the optic  100  according to any means or methods known in the art. Means and methods of attachment may include, but are not limited to, fasteners, glues, optical glues, adhesives, and the like. Additionally, optical grease may be applied between the attaching portions of the optic  100  to improve optical communication therebetween. 
     Continuing to refer to  FIG. 1  and referring additionally to  FIG. 2 , the receiving section  110  will now be discussed in greater detail. The receiving section  110  may be configured to receive light from a light source. More specifically, the receiving section  110  may be configured to receive light from a plurality of light sources. As such, the receiving section  110  may be configured to be positioned adjacent to a plurality of light sources. In some embodiments, where the plurality of light sources are arranged in a flat, generally planar configuration, the receiving section  110  may similarly be configured to be generally planar. More specifically, the receiving section  110  may comprise a receiving surface  112 , and the receiving surface  112  may be configured to be generally flat. In other embodiments, where the plurality of light sources are positioned in a generally arcuate configuration, the receiving surface  112  may be similarly configured to be generally arcuate, conforming to a curvature of the plurality of light sources. In the present embodiment, the receiving surface  112  is generally flat. Moreover, where the plurality of light sources to which the receiving section  110  is to be placed adjacent to are positioned in an array, the receiving surface  112  may be configured to have a geometric configuration that generally conforms to the configuration of the array of light sources. In the present embodiment, the receiving surface  112  has a generally rectangular configuration, forming a square with rounded corners. This geometric configuration is exemplary only, and all other configurations are contemplated and included within the scope of the invention, including, but not limited to, circles, ovals, ellipses, triangles, and any other polygon. Moreover, arcuate configurations of the receiving surface  112  are also contemplated and included within the scope of the invention. Such configurations include, but are not limited to, spherical or semi-spherical configurations, and any other ellipsoid. 
     The receiving surface  112  may be configured to include optical characteristics. In some embodiments, the receiving surface  112  may be polished so as to facilitate the maximum transmission of light therethrough. Additionally, the receiving surface  112  may be polished so as to have little or no refraction on light incident thereupon. Similarly, the receiving section  110  may be similarly formed so as to result in little or no refraction of light passing therethrough. More specifically, a body section  114  of the receiving section  110  may be configured so as to cause little or no refraction of light passing therethrough. Additionally, in some embodiments, each of the receiving surface  112  and the body section  114  may be configured to collimate light. More specifically, each of the receiving surface  112  and the body section  114  may be configured to collimate light in a direction orthogonal to a plane defined by the receiving surface  112 . In some embodiments, as in the present embodiment, the plane may be flat. In other embodiments, the plane may be curved. Furthermore, the body section  114  may be configured to include a plurality of collimating sections. Each collimating section may be configured to collimate light incident thereupon such that light from each collimating section does not propagate into an adjacent collimating section. 
     Additionally, in some embodiments, the receiving surface  112  may include a material applied thereto. For example, optical grease may be applied to the receiving surface  112  so as to facilitate the transmission of light between a light source and the receiving surface  112  when the receiving section  110  is positioned adjacent to a plurality of light sources. Furthermore, as another example, a color conversion layer (not shown) may be positioned adjacent the receiving surface  112 . The color conversion layer may be configured to receive light within a source wavelength range and convert the light, emitting a converted light within a converted wavelength range. The color conversion layer may be attached, deposited, or otherwise positioned on the receiving surface  112  by any means that is suitable to the material forming the color conversion layer. In some embodiments, the receiving surface  112  may include two or more color conversion layers positioned upon different sections of the receiving surface  112 . Each of the two or more color conversion layers may convert respective source lights of the same or differing wavelengths to respective converted lights of differing wavelengths. The receiving surface  112  may include any number of color conversion layers, including overlapping layers. Color conversion layers may be formed of material selected from the group consisting of phosphors, quantum dots, luminescent materials, fluorescent materials, and dyes. More details regarding the enablement and use of a color conversion layer may be found in U.S. patent application Ser. No. 13/073,805, entitled MEMS Wavelength Converting Lighting Device and Associated Methods, filed Mar. 28, 2011, as well as U.S. patent application Ser. No. 13/234,604, entitled Remote Light Wavelength Conversion Device and Associated Methods, filed Sep. 16, 2011, U.S. patent application Ser. No. 13/234,371, entitled Color Conversion Occlusion and Associated Methods, filed Sep. 16, 2011, and U.S. patent application Ser. No. 13/357,283, entitled Dual Characteristic Color Conversion Enclosure and Associated Methods, the entire contents of each of which are incorporated herein by reference. Moreover, the body section  114  may be formed of a material or a mixture of materials configured to perform a similar color conversion of light passing therethrough. 
     The body section  114  may include one or more side surfaces  115 . The number and configuration of side surfaces  115  may be defined by the geometric configuration of the receiving section  110 . The side surfaces  115  may be configured to prevent light from passing therethrough. In some embodiments, the side surfaces  115  may have an absorbing or reflecting material applied thereto. Furthermore, in some embodiments, the side surfaces  115  may be configured to redirect light incident thereupon emitted by the plurality of light sources and passing through the receiving surface  112  in the direction of the interfacing surface  116 . Additionally, each of the receiving surface  112  and the body member  114  may be configured to direct light so as to not be incident upon the side surfaces  115 . 
     Additionally, the receiving section  110  may further include an interfacing surface  116 . The interfacing surface  116  may be configured so as to facilitate the transmission of light from the receiving section  110  to the intermediate section  120 . The interfacing section  116  may be configured to include any or all of the optical characteristics described for the receiving surface  112  and the body section  114  described hereinabove. Moreover, the interfacing section  116  may have optical grease, a color conversion layer, or other material applied to or placed adjacent thereto, in addition to or exclusive of optical grease and/or a color conversion layer associated with the receiving surface  112 . 
     Additionally, the interfacing surface  116  may include an exposed surface  118 , being defined as the section of the interfacing surface  116  that is outside the periphery of the interface between the interfacing surface  116  and the intermediate section  120 . The exposed surface  118  may be configured to have the same optical characteristics as the rest of the interfacing surface  116  as described hereinabove, or it may have different characteristics. In some embodiments, the exposed surface  118  may be configured to absorb or reflect light incident thereupon, such that no light received by the receiving section  110  from the plurality of light sources passes through and is emitted by the exposed surface  118 . Moreover, each of the receiving surface  112  and the body section  114  may be configured to direct light, either by directed collimation or refraction, received from the plurality of light sources away from the exposed section  118  such that little or no light may pass therethrough. In some embodiments, the exposed surface  118  may be configured to refract light incident thereupon in the direction of the interfacing surface  116  that is interfaced with the intermediate section  120 . In some embodiments, the exposed surface  118  may be configured to refract light so as to emit generally diffuse light. 
     It is appreciated that where the optic  100  is formed as a single integral unit, or at least where the receiving section  110  and the intermediate section  120  are formed as a single integral unit, the interfacing surface  116  may be limited to the exposed surface  118 . 
     Continuing to refer to  FIG. 1 , the intermediate section  120  will now be discussed in greater detail. The intermediate section  120  may be configured to facilitate the transmission of light from the receiving section  110  to the emitting section  130 . Accordingly, the intermediate section  120  may be configured to receive light from the receiving section  110  and to emit light so as to be received by the emitting section  130 . 
     Furthermore, the intermediate section  120  may include optical characteristics so as to affect light passing therethrough. In some embodiments, the intermediate section  120  may be configured to collimate light passing therethrough. More specifically, the intermediate section  120  may be configured to collimate light in a direction generally orthogonal the plane defined by the receiving surface  112 . Furthermore, the intermediate section  120  may be configured to include a plurality of collimating sections. Each collimating section may be configured to collimate light incident thereupon such that light from each collimating section does not propagate into an adjacent collimating section. Moreover, in embodiments where the body section  114  of the receiving section  110  comprises a plurality of collimating sections, each collimating section of the intermediate section  120  may be associated with a collimating section of the body section  114  such that light collimated by each collimating section of the body section  114  remains collimated and continues in the established direction of travel in the associated collimating section of the intermediate section  120 . Furthermore, in some embodiments, each collimating section of the intermediate section  120  may be associated with a single light source of a plurality of light sources. In some embodiments, each collimating section may be the only collimating section associated with one or more light sources of a plurality of light sources. 
     In some embodiments, where the intermediate section  120  is formed separate and apart from at least one of the receiving section  110  and the emitting section  130 , the intermediate section  120  may be formed so as to facilitate the optical coupling thereto. For example, where the intermediate section  120  is formed separate from the receiving section  110 , the intermediate section  120  may have a lower surface  122  configured to interface with and optically couple to the receiving section  110 . More specifically, the lower surface  122  may be configured to interface with and optically couple to the interfacing surface  116  of the receiving section  110 . Moreover, the lower surface  122  may have a coating or layer of material applied thereto or positioned thereupon. In some embodiments, a color conversion layer, as described hereinabove, may be positioned adjacent to the lower surface  122  to convert light received from the receiving section  110 . Additionally, optical grease may be applied to the lower surface  122  to facilitate optical coupling between it and the interfacing surface  116 . 
     The lower surface  122  may be configured to have a geometry that is similar to or conforms to the geometry of the interfacing surface  116 . In the present embodiment, the lower surface  122  has a generally square configuration. It is appreciated that the lower surface  122  may have a geometry conforming to any polygon. Moreover, it is appreciated that the geometry of the lower surface  122  may define a surface area. In some embodiments, the surface area of the lower surface  122  may be approximately equal to a surface area of the interfacing section  116 , such that the lower surface  122  is generally coextensive with the interfacing section  116 . In some embodiments, the lower surface  122  may have a surface area that is less than the surface area of the interfacing surface  116 . In such embodiments, the exposed surface  118  may thereby be defined as the difference in surface area resulting in a portion of the interfacing surface  116  being exposed and not covered by the lower surface  122 . 
     Similarly, where the intermediate section  120  is formed separate from the emitting section  130 , the intermediate section  120  may include an upper surface  124  configured to optically couple to the emitting section  130 . The upper surface  124  may have any of the characteristics and additional features, including color conversion layers and optical grease, as the lower surface  122 . 
     It is appreciated that in embodiments where the intermediate section  120  is integrally formed with either of the receiving section  110  and the emitting section  130 , the lower and upper surfaces  122 ,  124 , respectively, may be absent in such embodiments. 
     The intermediate section  120  may further include a body section  126 . The body section  126  may be configured to facilitate the traversal of light therethrough, from the lower surface  122  to the upper surface  124 . Moreover, the body section  126  may be configured to have optical characteristics to affect light passing therethrough. Any of the characteristics as described for the body section  114  of the receiving section  110  may be included in the body section  126  of the intermediate section  120 . 
     Furthermore, the body section  126  may have one or more sidewalls  128 . The sidewalls  128  may be configured to have a curvature  129 . The curvature  129  may be necessitated by a difference in the surface areas of the lower surface  122  and the upper surface  124 . The sidewalls  128  may be configured to redirect light incident thereupon, as a result of the differences in the surface areas of the lower and upper surfaces  122 ,  124 , in the direction of the upper surface  124 . 
     Continuing to refer to  FIGS. 1 and 2 , the emitting section  130  will now be discussed in greater detail. The emitting section  130  may be configured to receive light from the intermediate section  120  and to emit the received light. More specifically, the emitting section  130  may be configured to emit light in such a manner so as to enable the control of the direction of light emitted from the optic  100 . 
     The emitting section  130  may include a plurality of facets  132 . Each facet  132  may be configured to emit light. More specifically, each facet  132  may be configured to emit light in a particular direction. In some embodiments, each facet  132  of the plurality of facets  132  may be configured to emit light in a direction that is unique from the direction of light emitted by the other facets  132  of the plurality of facets  132 . 
     The plurality of facets  132  may be configured so as to enable a user to selectively emit light from a plurality of light sources, the emitted light being received by the receiving surface  112 , passing through each of the receiving section  110  and the intermediate section  120 , and being emitted by the emitting section  130  through one or more of the plurality of facets  132  in a direction selected by the user. In some embodiments, when a user operates a single light source of the plurality of light sources, light may be emitted by a single facet  132  of the plurality of facets  132  in a single direction, such that the optic  100  emits light only from that facet  132 , and hence only in that direction. Accordingly, in some embodiments, each facet  132  may be associated with a single light source of a plurality of light sources. Moreover, in some embodiments, each facet  132  of the plurality of facets  132  may be the only facet associated with the light source. In some other embodiments, two or more facets  132  of the plurality of facets  132  may be associated with a single light source. In some embodiments, two or more light sources may be associated with a single facet  132 . Where a single facet  132  is configured to be associated with two or more light sources, light emitted by the two or more light sources may combine to form a combined light. In some embodiments, the combined light may be a white light. It is contemplated and included within the scope of the invention that any combination of light, or specifically, light having differing wavelengths ranges corresponding to differing colors, may combine to form a combined light that is a member, a light that is perceived as a combination of the two colors. 
     Each facet may have a projected surface area that corresponds and generally conforms to a section of the upper surface  124  of the intermediate section  120 . In some embodiments, where the intermediate section  120  comprises a plurality of collimating section, each facet  132  may have associated with it one or more collimating sections. In such embodiments, each facet  132  may be associated with the light source(s) with which the associated collimating section of the intermediate section  120  is associated. 
     Each facet  132  of the plurality of facets  132  may include an emitting surface  134  and one or more redirecting surfaces  136 . The redirecting surfaces  136  may be configured to redirect light in the direction of the emitting surface  134 . Accordingly, substantially all of the light emitted by the facet  132  may be emitted through the emitting surface  134 . The emitting surface  134  may be configured so as to emit light in a selected direction. Moreover, the emitting surface  134  may be configured to emit light having a selected divergence. In some embodiments, the emitting surface  134  may be configured so that the divergence of light emitted therefrom is relatively low, such that a spot light is emitted by the facet  132 . Accordingly, the optic  100  may be configured to emit light as a combination of a plurality of spot lights, each spot light being light emitted through each facet  132  of the plurality of facets  132 . 
     Referring now additionally to  FIG. 3 , additional aspects of the emitting section  130  will now be discussed in greater detail. In some embodiments, the emitting section  130  may be configured such that a portion  137  of the emitting section  130  is generally flat and surrounded by the plurality of facets  132 . Moreover, the generally flat portion  137  may be positioned such that the center  133  is located therein. 
     The emitting surface  134  of each facet  132  may be configured to emit light in a selected direction. More specifically, the emitting surface  134  of each facet  132  may be configured to emit light in a direction that is generally orthogonal to a plane defined by the emitting surface  134 . Accordingly, the direction in which light is emitted from each emitting surface  134  may be individual to each facet  132 , as the plane defined by the emitting surface  134  of each facet  132  may be skew to every other plane defined by the emitting surface  134  of every other facet  132  of the plurality of facets  132 . Moreover, the direction in which each facet  132  emits light may be measured in a polar system, whereby a line that is normal to the plane defined by the emitting surface  134  of each facet  132  may be measured in terms of first and second angles corresponding to a polar system. In some embodiments, each facet  132  may be configured to emit light in a direction such that at least one of the first and second angles formed by the line normal to the plane defined by the emitting surface  134  of the facet  132  is non-equal to the first or second angle, respectively, every other line normal to the plane defined by the emitting surface  134  of the other facets  132  of the plurality of facets  132 . In some embodiments, a facet  132  may be configured to emit light in a direction such that at least one of the first and second angles formed by the line normal to the emitting section  134  of the facet  132  is equal to the first and/or second angle, respectively, of a line normal to the emitting section  134  of at least one other facet  132  of the plurality of facets  132 . 
     The direction in which each facet  132  is configured to emit light may be selected based on any desired distribution of light, either individually to each facet  132  or in various combinations of facets  132  of the plurality of facets  132 . Moreover, the direction in which each facet  132  is configured to emit light may be selected based on a pattern or methodology. In the present embodiment, the plurality of facets  132  may be configured to emit light in a direction that is a function of the location of the facet  132  within the emitting section  130 . More specifically, the plurality of facets  132  may be configured to emit light in the direction it is a function of the location of the facet  132  relative to the center  133  of the emitting section  130 . In the present embodiment, each facet  132  may be configured to emit light generally in the direction of a line  135  that is normal to the generally flat portion  137  of the emitting section  130  and passing through the center  133 . In some other embodiments, each facet  132  may be configured to emit light generally in a direction away from the line  135 . This methodology of configuring the plurality of facets  132  is exemplary only, and any other pattern or methodology of configuring the plurality of facets  132  is contemplated and included within the scope of the invention. 
     In some embodiments, the plurality of facets  132  may include a color conversion layer. The color conversion layer may be formed of any material script hereinabove. In some embodiments, the color conversion layer may be positioned adjacent to the emitting surface  134  of each facet  132 . In some embodiments, a color conversion material may be integrally formed with each facet  132 . A first color conversion material may be associated with the first facet  132 , and the second color conversion material may be associated with a second facet  132 . The first color conversion material may be configured to emit a converted light within a first wavelength range corresponding to a first color, and the second color conversion material may be configured to emit a converted light within a second wavelength range corresponding to a second color. Moreover, in some embodiments, more than one color conversion material may be present and associated with a single facet  132  such that a portion of the light emitted by the facet  132  may be within a first wavelength range, and another portion of the light emitted by the facet  132  may be within a second wavelength range. Furthermore, where a facet  132  includes a color conversion layer configured to convert a source light within a source wavelength range and emit a converted light within a converted wavelength range, only a portion of the light that is emitted by the facet  132  may be converted, such that the light emitted by the facet  132  is a combination of light within the source wavelength range and light within the converted wavelength range. 
     Referring now to  FIGS. 4-5 , additional aspects of the present invention will now be discussed.

     The base member  210  may be configured to permit the plurality of light sources  220  to be positioned thereupon so as to emit light that is incident upon the optic  100 . More specifically, the base member  210  may be configured to permit the plurality of light sources  220  to be positioned thereupon so as to emit light that is incident upon the receiving section  110 .

Moreover, each LED  221  of the plurality of LEDs  221  may be selected so as to emit light selected lighting characteristics when emitted by the optic  100 . For example, where an element of the optic  100  includes color conversion material, an LED  221  configured to emit light within a wavelength range corresponding to a source wavelength range for the color conversion material such that light emitted by the LED  221  is incident upon the color conversion material and the color conversion material may emit a converted light within a converted wavelength range. 
     The base member  210  may include an upper surface  212 , one or more side surfaces  214 , a lower surface  216 , and a thickness  218  between the upper surface  212  and the lower surface  216 . Each of the upper surface  212 , the lower surface  216 , and the thickness  218  may be configured to permit the positioning of the plurality of light sources  220  thereupon. Additionally, in some embodiments, each of the upper service  212  and the lower surface  216  may be configured to permit the plurality of light sources  220  to be positioned in optical communication with the optic  100 . The nature of the light source  220 , for example, its structural characteristics and light emission distribution characteristics may alter the nature of the configuration of each of the upper surface  212  and the lower surface  200 . 
     In the present embodiment, where the plurality of light sources  220  includes a plurality of LEDs  221 , the base member  210  may be configured to permit each LED  221  of the plurality of LEDs  221  to be positioned in optical communication with the optic  100 . More specifically each of the upper surface  212 , the lower surface  216 , and the thickness  218  may be configured to permit each LED  221  of the plurality of LEDs  221  to be positioned in optical communication with the optic  100 . In the present embodiment, the lower surface  216  may include a plurality of cavities  217 . Each cavity  217  may extend into the thickness  218  and may be configured to permit an LED  221  to be positioned at least partially there within. More specifically, each cavity  217  may be configured to permit a light-emitting portion of an LED  221  to be positioned therein. 
     Additionally, the upper surface  212  may include a plurality of features  213  configured to facilitate the optical communication between the plurality of LEDs  221  and the optic  100 . The arrangement of the plurality of features  213  on the upper surface  212  may correspond to the arrangement of the plurality cavities  217  on the lower surface  216 . More specifically, the plurality of cavities  217  may extend through the thickness  218  such that light emitted by an LED  221  positioned within each individual cavity  217  may be incident upon an associated feature  213 . Accordingly, each cavity  217  of the plurality of cavities  217  may be associated with a feature  213  of the plurality of features  213 . 
     The distribution of the cavities  217  and the features  213  may be configured to correspond with the distribution of the facets  132  of the optic  100 . In some embodiments, each pair of a cavity  217  and a feature  213  may be associated with a facet  132  of the plurality of facets  132 . In some embodiments, more than one pair of a cavity  217  and a feature  213  may be associated with a single facet  132 . In some embodiments a single pair of a cavity  217  and a feature  213  may be associated with more than one facet  132 . 
     The plurality of features  213  may be configured to facilitate the optical communication between the plurality of LEDs  221  and the optic  100 . In some embodiments, the plurality of features  213  may have a generally sloped profile. Additionally, in some embodiments, the plurality of features  213  may include an optical component  215 . The optical component  215  may be formed of a transparent or translucent material. Additionally, the optical component  215  may be configured to interact with light incident thereupon and passing there through so as to alter the characteristics of the instant light. For example, in some embodiments, the optical component  215  may be configured to reflect, refract, collimate, or otherwise redirect light incident thereupon. Additionally, in some embodiments, the optical component  215  say be configured to diffuse light incident thereupon. 
     Light that is emitted from each LED  221  of the plurality of LEDs  221  and emitted from the feature  213  associated with each LED  221  may be incident upon the receiving surface  112  of the optic  100 . More specifically, light emitted from each feature  213  may be incident upon the receiving surface  112  and pass therethrough, and may similarly be incident upon the intermediate section  120  and past therethrough, and may finally be incident upon the emitting section  130 . More specifically, light emitted from each feature  213  may be incident upon a facet  132  of the emitting section  130  and may be emitted by the facet  132 . Hence, light emitted by a feature  213  may result in the facet  132  associated with the feature  213  emitting light. As light is emitted from each feature  213 , it may be reflected, refracted, collimated, or otherwise redirected so as to be emitted by the facet  132  that is associated with the feature  213 . Such redirection may be accomplished by the inclusion of features configured to accomplish such redirection in any of the various elements of the light source structure member  200  and the optic  100  as disclosed hereinabove. Accordingly, when light is emitted from a feature  213 , light may be emitted from the optic  100  by the facet  132  in a direction that is normal to a plane defined by an emitting surface  134  of the facet  132 . As each feature  213  is associated with an LED  221  of the plurality of LEDs  221 , when a single LED  221  is operated, the light emitted from the operated LED  221  may be emitted, in some embodiments, by a single facet  132  in a direction that is normal to a plane defined by the emitting surface  134  of the facet  132 . Accordingly, the direction in which light is emitted from the optic  100  may be controlled by the selective operation of the LEDs  221  of the plurality of LEDs  221 . 
     The base member  210  may be configured to have a geometric shape. Some embodiments, the base member  210  may be configured to have substantially the same shape as the optic  100 . More specifically, the base member  210  may be configured to have substantially the same geometric shape as the receiving section  110  of the optic  100 . In the present embodiment, the base member  210  may have a generally square shape. The base number  210  may be configured to have a shape conforming to any polygon. 
     The base member  210  may further include a plurality of attachment ports  222 . The plurality of attachment ports  222  may facilitate the attachment of the base member  210  to a structure. In some embodiments, the plurality of attachment ports  222  may permit the base member  210  to be attached to a support structure. Such an embodiment will be discussed in greater detail hereinbelow. In some embodiments, the plurality of attachment ports  222  may facilitate the attachment of the base member  210  to a structural surface, such as a wall, ceiling, or floor. The plurality of attachment ports  222  may be configured to permit the positioning of a fastener therethrough. Accordingly, in some embodiments, the plurality of attachment ports  222  may be formed as an aperture through the thickness  218  of the body member  210 , such that a fastener may pass from the upper surface  212  to the lower surface  216  and beyond. Additionally, in some embodiments, the aperture may be countersunk. This method of attachment is exemplary only, and any and all other means or methods of attachment known in the art are contemplated and included within the scope of the invention. 
     Continuing to refer to  FIG. 4 , the optic attachment members  230  will now be discussed in greater detail. The optic attachment members  230  may be configured to facilitate the positioning of an optic  100  adjacent to the upper surface  212 . More specifically, the optic attachment members  230  may be configured to facilitate the positioning of an optic  100  adjacent to, and in optical communication with, the plurality of features  213  of the upper surface  212 . Additionally, the optic attachment members  230  may be configured to retain and carries the optic  100  and a selected position relative to the light source structure member  200 , preventing the movement of the optic  100  relative to the light source structure member  200 . Each optic attachment member  230  may be configured as an outcropping extending generally away from the upper surface  212 . In some embodiments, the optic attachment members  230  may extend in a direction generally orthogonal to the upper surface  212 . 
     Each optic attachment member  230  may include a base section  232 , an extension section  234 , a rounded section  236 , and an upper section  238 . The base section  232  may be generally adjacent to the upper surface  212 . In some embodiments, the base section  232  may be configured to facilitate the attachment of the optic attachment member  230  to the upper surface  212 . Any method or means of attachment as is known in the art may be used, including, but not limited to, adhesives, glues, welding, fasteners, and the like. It is contemplated included within the scope of the invention that, in some embodiments, the optic attachment members  230  may be integrally formed with the base member  210 . The extension section  234  may extend generally away from the base section  232  in a direction generally away from the upper surface  212 . In some embodiments, the extension section  234  may be sloped, more specifically, maybe sloped generally inward from a perimeter defined by the base section  232 . The perimeter defined by the base section  232  may generally define the shape of the extension section  234 . In the present embodiment, the base section  232  is generally circular in shape, thereby defining a circular perimeter. As such, the extension section  234  is generally cylindrical in shape. However, where the extension section  234  is sloped, the extension section  234  may be generally conical in shape. More specifically, the extension section  234  may be generally frustoconical in shape. 
     The rounded section  236  may be positioned adjacent to an end of the extension section  234  generally opposite the base section  232 . The rounded section  236  may be rounded inward in the direction of the upper section  238 . The upper section  238  may define an upper end the optic attachment member  230 . Moreover, in some embodiments, the upper section  238  may be generally flat. 
     The optic attachment members  230  may be configured attached to the optic  100  so as to position the optic  100  as described hereinabove. In some embodiments, the optic attachment members  230  may be configured to attach removably the optic  100 . Any means or method of attachment as is known in the art may be employed, moving, but not limited to, adhesives, glues, interference fits, frictional fits, welding, fasteners, and the like. 
     In the present embodiment, the optic attachment members  230  may be configured to extend into a section of the optic  100  that is configured to receive the optic attachment members  230 . More specifically, the material of each optic attachment member  230  may facilitate the attachment of the optic  100  to the optic attachment members  230 . For example, the optic attachment members  230  may be formed of a material having a generally increased coefficient of friction. Moreover, the optic attachment members  230  may be formed of a material that is generally compressible. Accordingly, where the optic attachment members  230  are positioned within a section of the optic  100  configured to receive the optic attachment members  230 , the optic  100  may generally compress the optic attachment members  230  and, more specifically, may compress at least one of the extension section  234  and the rounded section  236 , increasing the friction therebetween and attaching thereby. This method of attaching the optic  100  to the optic attachment members  230  is exemplary only and does not limit the scope of methods of attachment. An optic  100  that has been attached to the light source structure member  200  is illustrated, for example, in  FIG. 6 . 
     Referring now to  FIG. 7 , additional aspects of the attachment between the optic  100  and the light source structure member  200  will now be discussed in greater detail. As disclosed hereinabove, the optic  100  may be positioned adjacent to the light source structure member  200  such that each feature  213  is positioned in optical communication with an associated facet  132 . For example, in the present embodiment, a first feature  213 ′ may be positioned in optical communication with a first facet  132 ′. Additionally, a second feature  213 ″ may be positioned in optical communication with a second facet  132 ″. The positioning of each of the first and second features  213 ′,  213 ″ in optical communication with each of the first and second facets  132 ′,  132 ″ will depend on the optical characteristics of all of the elements, as well as the optical characteristics generally of the light source structure member  200  and the optic  100 . In the present embodiment, each of the first and second features  213 ′,  213 ″ may be positioned so as to be generally vertically aligned with each associated feature  132 ′,  132 ″, respectively. Accordingly, light may be emitted by each of the first and second features  213 ′,  213 ″, propagate generally upwards, and be emitted by the emitting surface  134  of each of the first and second facets  132 ′,  132 ″. Similar positioning may be adopted for the remaining facets  132  of the plurality of facets  132  and features  213  of the plurality of features  213 . 
     Referring now to  FIG. 8 , an additional embodiment of the invention will now be discussed in greater detail. In  FIGS. 6-7 , a single pair (or combination) of an optic  100  and a light source structure member  200  was discussed. In some embodiments of the invention, more than one combination of an optic  100  and a light source structure member  200  may be included in a single lighting device, each combination being referred to as a lighting structure. As shown in  FIG. 8 , many of such lighting structures are depicted as being included in a lighting device  800 . The lighting device  800  may include a plurality of lighting structures  850 . Each lighting structure  850  of the plurality of lighting structures  850  may be a combination of an optic  100  and a light source structure member  200  as described hereinabove. Each lighting structure  850  may be positioned so as to be adjacent to at least one other lighting structure  850  of the plurality of lighting structures  850 . For example, in some embodiments, two lighting structures  850  may be provided. The lighting structures  850  may be positioned such that a first plane defined by the lower surface  216  of one of the lighting structures  850  is skew to a second plane defined by the lower surface  216  of the other lighting structure  850 . Furthermore, in some embodiments, the first plane may be perpendicular to the second plane. 
     Additionally, in some embodiments, the plurality of lighting structures  850  may be positioned so as to define a geometric shape of the lighting device  800 . In the present embodiment, the plurality of lighting structures  850  is positioned so as to define a generally cubic shape. It is contemplated, however, and intended to be included within the scope of the invention, that any other geometric configuration resulting from the positioning of the plurality of lighting devices  850  defining a shape may be arranged, including, but not limited to, pyramids, boxes, or any other polyhedron, including regular polyhedral shapes. In some embodiments, a complete polyhedron may not be defined, wherein at least one face of the polyhedron is left unoccupied by a lighting structure  850 . Such embodiments may be advantageous where the lighting device  800  is to be attached to a surface of an external structure. 
     Additionally, the geometric configuration of the lighting device  800  may depend upon the shape of each lighting structure  850 . In the present embodiment, where each lighting structure  850  has a generally square shape, the plurality of lighting structures  850  may readily be arranged to form a lighting device  800  having a generally cubic shape. In some embodiments, the plurality of lighting structures  850  may have a geometric configuration other than a square, and, accordingly the lighting device  800  may have a geometric configuration of the shape other than acute. Additionally, in some embodiments, the shape of one lighting structure  850  is different from the shape of another lighting structure  850 , the geometric configuration of the lighting device  800  may be determined as a result of the variation in shapes between the various lighting structures  850 . 
     In some embodiments, as in the present embodiment, the plurality of lighting structures  850  may be positioned so as to be immediately adjacent to one another. In some embodiments, the lighting device  800  may include a support structure (not shown). The support structure may be configured to position the plurality of lighting structures  850  into a selected arrangement. For example, in the present embodiment, the support structure may be configured to position the plurality of lighting structures  850  into a generally cubic shape. Each lighting structure  850  may be attached to the support structure any means or method known in the art. For example, the support structure may be configured to cooperate with the attachment ports  222  of the light source structure member  200 . More specifically, the support structure may be configured to permit the attachment of a fastener thereto, wherein the fastener is positioned so as to pass through an aperture of the attachment ports  222 , as shown in  FIGS. 4-5 , thereby attaching the light source structure member  200  to the support structure. Each lighting structure  850  may be similarly attached to the support structure in this manner. 
     Referring now to  FIG. 9 , additional aspects of the lighting device  800  will now be discussed in greater detail. The plurality of lighting structures  850  may be positioned so as to define internal cavity  810 . Each of the lower surfaces  216  of the light source structure members  200  of the plurality of lighting structures  850  may define a boundary of the internal cavity  810 . Various electrical components utilized in the operation of each lighting structure  850  of the plurality of lighting structures  850  may be positioned within the internal cavity  810 . In some embodiments, the electrical components utilized in the operation of the plurality of lighting structures  850  may be attached to and carried by support structure. 
     Referring now to  FIG. 10 , a schematic representation of an embodiment of the electrical components of a lighting device  1000  according to an embodiment of the invention will now be discussed in greater detail. As recited hereinabove, the lighting device  1000  may include electrical components to enable and control the operation of the plurality of lighting structures  1040 . Examples of such electrical components may include a controller  1010  and a power circuit  1020 . The power circuit  1020  may be configured to be positioned in electrical communication with an external power source  1030 , and may be configured to condition, rectify, and otherwise alter electricity received from the power source  1030  so as to be used by the various electrical components of the lighting device  1000 , including the controller  1010  and the plurality of lighting structures  1040 . Accordingly, the power circuit  1020  may be positioned in electrical communication with the controller  1010  and each lighting structure of the plurality of lighting structures  1040 . In some embodiments, the controller  1010  and the power circuit  1020  may be contained on a single circuit board, and may be considered a single integral electronic component. 
     The controller  1010  may be positioned in electrical communication with each lighting structure  1040  of the plurality of lighting structures  1040  and may be configured to control the operation of each lighting structure  1040  of the plurality of lighting structures  1040 . For example, the controller  1010  may be positioned in electrical communication with each of a first lighting structure  1041 , a second lighting structure  1042 , and an nth lighting structure  1043 . More specifically, the controller  1010  may be configured to control the operation of the plurality of LEDs  221  of each of the plurality of lighting structures  850 . For example, referring now back to  FIGS. 4-7 , the controller  1010  may be configured to operate a single LED  221  of the plurality of LEDs  221 , thereby causing the first feature  213 ′ of the plurality of features  213 , which is associated the single LED  221  the controller  1010  selectively operates, thereby causing the first facet  132 ′ to emit light. The controller  1010  may be configured to selectively operate each individual LED  221  of the plurality of LEDs  221 , thereby enabling the controller  1010  to selectively emit light from each facet  132  of the plurality of facets  132 . Accordingly, the controller  1010  may be configured to control the direction in which light is emitted from the lighting device  800  by selectively operating at least one LED  221  of the plurality of LEDs  221  of at least one of the plurality of lighting structures  1040  of the lighting device  800 . The direction in which light is emitted from the lighting device  800  and the result of the lighting structure  1040  that the LED  221  operated by the controller  1010  is contained within, and configuration of the facet  132  associated with the LED  221  operated by the controller  1010 , namely, the direction in which the emitting surface  134  of the facet  132  is configured to emit light. 
     Referring now to  FIG. 11 , a schematic representation of an alternative embodiment of the electrical components of a lighting device  1100  will be discussed in greater detail. As in the embodiment presented in  FIG. 10 , the lighting device  1100  may include a controller  1110  and a power circuit  1120 . In the present embodiment, each of the plurality of lighting structures  1140  may comprise a sub-controller  1150 . More specifically, each sub-controller  1150  of the plurality of lighting structures  1140  may be configured to be positioned in electrical communication with the controller  1110  and to receive instructions therefrom. Moreover, each sub-controller  1150  may be configured to operate the plurality of LEDs  221  of the associated lighting structure, one of the first lighting structure  1141 , the second lighting structure  1142 , or the n th  lighting structure  1143 , responsive to the instructions received from the controller  1110 . In this way, a less sophisticated electrical electronic controller device may be utilized as controller  1110 , as it need only communicate and instruction to each sub-controller  1150 , which may then interpret the instruction to operate an associated plurality of LEDs according to the configuration of the sub-controller  1150 . 
     Referring now to  FIG. 12 , a schematic of an alternative embodiment of a lighting device  1200  will now be discussed in greater detail. In the present embodiment, the lighting device  1200  includes a controller  1210 , a power circuit  1220 , and a single lighting structure  1230 . In such an embodiment, the controller  1210  may be configured to control the operation of the lighting structure  1230  as described hereinabove. 
     Referring now to  FIGS. 13 and 14 , an alternative embodiment of the invention will now be discussed. In the present embodiment, the lighting device  1300  may include an optic  1310  and a light source structure member  1320  as described hereinabove. Furthermore, the lighting device  1300  may additionally include a reflective housing member  1330 . The reflective housing member  1330  may include a wall  1331  having a reflective inner surface  1332  configured to reflect light incident thereupon. Additionally, the reflective inner surface  1332  may be configured to have a contour so as to selectively redirect light that is incident thereupon. In some embodiments, the reflective inner surface  1332  may be configured to redirect light incident thereupon in the direction of a gap  1334  between the reflective housing  1330  and the optic  1310  and the light source structure member  1320  such that light reflected by the reflective inner surface  1332  may propagate into the environment surrounding the lighting device  1300 . 
     Additionally, the reflective housing  1330  may be configured to preserve the directional control of light emitted by the lighting device  1300 . Accordingly, the reflective housing  1330  may be configured to redirect light that is incident upon various sections of the reflective inner surface  1332  such that light emitted by a first facet  1312  of the optic  1310  may be emitted from the lighting device  1300  in a first direction, and light emitted by a second facet  1314  of the optic  1310  may be emitted from the lighting device  1300  in a second direction. More specifically, a first facet  1312  of the optic  1310  may emit light that propagates through an optical chamber  1336  defined by the reflective inner surface  1332 , is incident upon a first section  1338 ′ of the reflective inner surface  1332 , and is redirected through the gap  1334  at an angle and in a direction that is unique indistinguishable from light emitted by the second facet  1314  which is then incident upon a second section  1338 ″ of the reflective inner surface  1332  and redirected through the gap  1334 . Accordingly, light may be emitted from any facet of the optic  1310 , reflected by the reflective inner surface  1332 , and emitted from the lighting device  1300  in a spotlight-like configuration as described hereinabove. 
     Additional details regarding the lighting device  1300  will now be discussed. The geometric configuration of the reflective housing  1330  may be determined based on the geometric configuration of the optic  1310 . More specifically, where the optic  1310  has a generally square configuration, the reflective housing  1330  may similarly have a generally square configuration, whereby a lower edge  1339  of the reflective housing  1330  defines its shape. 
     In some embodiments, the reflective housing  1330  may include a color conversion layer positioned adjacent to the reflective inner surface  1332  such that light emitted by the optic  1310  is received by the color conversion layer and a converted light is emitted thereby prior to being reflected out of the lighting device  1300 . The color conversion layer may be the substantially the same as color conversion layers described hereinabove. 
     Referring now to  FIG. 15  and alternative embodiment of the invention will now be discussed in detail. In the present embodiment, a lighting device  1500  may comprise a controller  1510 , a power circuit  1520 , a plurality of lighting structures  1530 , and a network interface device  1540 . The network interface device  1540  may be positioned in electrical communication with the controller  1510  and may be configured to transmit an instruction to the controller  1510 . Additionally, the network interface device  1540  may be configured to communicate electronically with a network  1550 . The network  1550  may be any type of computerized network as is known in the art. The network interface device  1540  may be configured to receive an instruction from a remote computerized device  1560  across the network  1550 . The network interface device  1540  may be configured to then transmit the instruction to the controller  1510 . The controller  1510  may be configured to operate the plurality of lighting structures  1530  responsive to the instructions received from the network interface device  1540 . The instruction may cause the controller  1510  to operate a light source of the plurality of light sources associated with a lighting structure  1530  of the plurality of lighting structures  1530 . 
     Referring now to  FIG. 16 , an additional aspect of the invention will now be discussed. In the present embodiment, the lighting device  1600  may be positioned so as to emit light into a room  1610 . The lighting device  1600  may be configured according to any of the lighting devices described hereinabove. More specifically, the lighting device  1600  may be configured to communicate across the network  1550  as described in the lighting device represented in  FIG. 15 . Accordingly, the lighting device  1600  may operate responsive to an input received across the network  1550 . 
     One method of using the lighting device  1600  may be to indicate a location within the room  1610 . For example, the lighting device  1600  may be operated so as to illuminate a first location  1612  within the room  1610 . This may be accomplished by operating a single LED of a plurality of LEDs of the lighting device  1600 , which may result in light being emitted from a single facet of the lighting device  1600  as described hereinabove. The light emitted by the single facet may result in light propagating through a volume of the room  1610  and being incident upon the first location  1612 . In this way, the lighting device  1600  may indicate to an observer the first location  1612 . The purpose of such an indication of the first location  1612  may depend entirely upon the intended use by the user. For example, in some embodiments, where the room  1610  is contained within a retail commercial establishment, the first location  1612  may indicate the location of a particular good. In some embodiments, the first location  1612  may indicate the location of a good that has run out of stock and requires restocking. 
     Furthermore, the lighting device  1600  may be operated so as to illuminate a second location  1614  within the room  1610 . The illumination of the second location  1614  may be concurrent with the illumination of the first location  1612 , or they may occur in a sequential fashion. Similarly, the lighting device  1600  may be operated so as to illuminate a third location  1616  within the room  1610 . The illumination of the third location  1616  may be concurrent with the illumination of each or either of the first location  1612  and the second location  1614 , or it may occur in a sequential illumination of each of the first, second, and third locations  1612 ,  1614 ,  1616 . In this manner, the lighting device  1600  may indicate a motion of direction by the sequential illumination of the first, second, and third locations  1612 ,  1614 ,  1616 . This may indicate a suggested direction of travel to an observer. This may be desirable in a retail shopping setting, where the lighting device  1600  may indicate the direction in which an observer may travel in order to find a particular location or good. Additionally, this may be desirable in emergency situations, where the lighting device  1600  may indicate a safe direction of travel towards an exit  1618  of the room  1610 . 
     The above-mentioned scenarios are exemplary only, and the lighting device  1600  may be used in any method, manner, or setting in which directional illumination is desirable.
