The opposing set of base structures can be connected by a lens wall. The combination of the lens wall and the opposing base structures can include inner filler therein. The lighting sources can radiate light, which can react with the inner filler and the lens wall to further radiate light past the lens wall.

[0027]Referring now to FIG. 1, therein is shown a vertical cross-sectional view of an electrical system 100 with lighting configuration along a line 2-2 of FIG. 2 in an embodiment of the present invention. The horizontal direction can be represented along the ‘X-axis’ and the vertical direction can be represented along the ‘Y-axis’ for FIG. 1.
[0028]The electrical system 100 can include a variety of devices or elements, such as a lamp, a visual signaling device, a lighting component within a larger system or device, or a combination thereof. The electrical system 100 can be included in a personal device, an enterprise system, a building or civil structures, or a combination thereof. The electrical system 100 can further include or couple with a controller, a management system, a power system, or a combination thereof.
[0029]The electrical system 100 can include a set of base structures 106. The base structures 106 can include objects, items, or portions within an object or item that provides attachment or reference for other structures. For example, the base structures 106 can include or correspond to a casing, a platform, a frame, portions therein, or a combination thereof.
[0030]As a more specific example, the base structures 106 can include substrates or wafers, such as thin slices of non-electrically-conductive or semi-conductive material. Also as a more specific example, the base structures 106 can include printed circuit boards (PCB), caps of a light bulb, a portion therein, or a combination thereof.
[0031]The base structures 106 can be opposing each other. For example, one of the base structures 106 can be above another separated by a gap. Also for example, the base structures 106 can overlap each other. Also for example, the base structures 106 can each be planar and oriented parallel to each other.
[0032]The electrical system 100 can include one or more instances of opposing light sources 108. The light sources 108 can include a first light source 107, a second light source 109, or a combination thereof. The first light source 107 and the second light source 109 can be vertically separated. The first light source 107 can be horizontally aligned relative to the second light source 109, mirrored or arranged in a complementary manner across a horizontal plane between the first light source 107 and the second light source 109, or a combination thereof.
[0033]The opposing group of the light sources 108 can each be a light emitting diode (LED). For example, the opposing light sources 108 can include one or more pairs of LEDs arranged or located on the base structures 106 to have physical association or relation to each other. As a more specific example, the opposing light sources 108 can include LED chips.
[0034]The opposing light sources 108 can each be attached to or integral with one instance of the base structures 106. For example, the opposing light sources 108 can be attached using a chemical adhesive, a mechanical or a structural connector, such as a brace or solder, or a combination thereof. Also for example, the opposing light sources 108 can be integral with the base structures 106 by sharing a structure or a component therein, such as by a chemical reaction, as a result of sintering or melting, or a combination thereof.
[0035]The base structures 106 can provide electrical power to the opposing light sources 108. The base structures 106 can further provide controls or regulators for the opposing light sources 108. The base structures 106 can include wires, traces, passive or active components, circuitry, or a combination thereof for providing the power, controlling or regulating, or a combination thereof for the opposing light sources 108.
[0036]The opposing light sources 108 can be separated vertically and aligned horizontally according to an arrangement or location on the base structures 106. The opposing light sources 108 can be located on the base structures 106 to have the opposing light sources 108 overlapping each other. Continuing with the example, for a paired set of LEDs, one of the LEDs can be attached to or integral with one substrate and the other LED can be attached to integral with the other substrate. The LEDs can be arranged or located such that they are facing or opposing each other, vertically separated, and horizontally aligned to overlap each other.
[0037]The electrical system 100 can further include a lens wall 110. The lens wall 110 is a structure allowing light to pass through. The lens wall 110 can further include the structure utilized in generating or emitting light. The lens wall 110 can further include a structure or a coating on an inner material. For example, the lens wall 110 can include silicone, phosphor, other similar material for illuminating or altering light, or a combination thereof formed in a cylindrical or a column shape. Also for example, the lens wall 110 can include silicone, phosphor, other similar material for illuminating or altering light, or a combination thereof applied as a coating to a solid filling structure.
[0038]The lens wall 110 can extend along a vertical direction between the base structures 106. The lens wall 110 can correspond to an outer perimeter surface in the horizontal direction. The lens wall 110 can further be attached to the base structures 106.
[0039]The lens wall 110 can correspond to a horizontal dimension 114 including a horizontal mid-region 116 and a vertical dimension 118 including a vertical mid-region 120. The horizontal dimension 114 can correspond to a width, a diameter, a portion thereof, or a combination thereof of the lens wall 110 or a shape thereof along the horizontal direction. The horizontal mid-region 116 can correspond to a mid-point or an area surrounding the mid-point for the horizontal dimension 114.
[0040]The vertical dimension 118 can include a length or a height of the lens wall 110 or a shape thereof along the vertical direction, with the vertical mid-region 120 corresponding to a mid-point or an area surrounding the mid-point for the vertical dimension 118. The base structures 106 can be spaced apart at a distance corresponding to or matching the vertical dimension 118 of the lens wall 110, the inner filler 122, or a combination thereof.
[0041]The lens wall 110 can further surround the light sources 108. For example, the light sources 108 can be located in relationship to the horizontal mid-region 116. As a more specific example, the light sources 108 can include one LED chip on each of the base structures 106 located or centered on the horizontal mid-region 116 of each of the base structures 106. Also as a more specific example, the light sources 108 can include a set of LED chips on each of the base structures 106 located and arranged equally about the horizontal mid-region 116.
[0042]The lens wall 110 and the base structures 106 can form an enclosed space. The electrical system 100 can include inner filler 122 within the enclosed space. The inner filler 122 is a light dispersing material for optimizing transmission of light from the light sources 108. The inner filler 122 can include viscous material or solid material. For example, the inner filler 122 can include silicone, phosphor, or a combination thereof.
[0043]The inner filler 122 can encapsulate the light sources 108. The inner filler 122 can contact the lens wall 110 and the base structures 106. The inner filler 122, the lens wall 110, or a combination thereof can provide a uniform medium for protecting the light sources 108, as well as for providing a light dispersing media for light generated by the light sources 108. The inner filler 122, the lens wall 110, or a combination thereof can further change or alter the light generated by the light sources 108, such as for wave lengths, colors, intensity, or a combination thereof.
[0044]For example, the light sources 108 can be embedded in the inner filler 122, such as silicone. The surface of the inner filler 122 can be then coated with the lens wall 110, such as silicone and phosphor.
[0045]Also for example, the light sources 108 can be coated with phosphor and silicone and then encapsulated in silicone for the inner filler 122. The lens wall 110 can be the outer edge or surface at the horizontal ends of the inner filler 122.
[0046]The inner filler 122, the lens wall 110, or a combination thereof can form an optical lens directing or redirecting light transmitted from the light sources 108. The inner filler 122, the lens wall 110, or a combination thereof can further transform the light transmitted from the light sources 108, such as by changing the wave length or the color.
[0047]The electrical system 100 can include the light sources 108, the lens wall 110, the inner filler 122, the horizontal dimension 114, the vertical dimension 118, or a combination thereof specifically configured according to light intensity perceived along the horizontal direction. The electrical system 100 can include the light sources 108, the lens wall 110, the inner filler 122, the horizontal dimension 114, the vertical dimension 118, or a combination thereof specifically configured to correspond to a target light intensity profile along the vertical dimension 118 with intensity levels corresponding to locations or points along the vertical dimension 118.
[0048]As a more specific example, the horizontal dimension 114 and the vertical dimension 118 can be controlled to provide a more uniform intensity level of lateral radiation along the vertical dimension 118. An aspect ratio corresponding to a ratio between the horizontal dimension 114 and the vertical dimension 118 can be directly related to degree of intensity near the vertical mid-region 120. The aspect ratio can be controlled to provide the uniform intensity.
[0049]It has been discovered that the light sources 108 including LEDs at opposite ends of and encapsulated by the inner filler 122 and the lens wall 110 provide optimized light output. The light output along the horizontal direction can drastically reduce as the perception point moves further away from an LED along the vertical direction. The opposing LEDs with the inner filler 122 and the lens wall 110 in between can provide greater total amount of light output and further provide a more uniform light intensity throughout the vertical direction of the electrical system 100 as perceived in lateral direction.
[0050]It has further been discovered that the aspect ratio and the light sources 108 can be used to provide more uniform light intensity across the vertical dimension 118. The aspect ratio can be controlled to create additive effect in light intensity from the two opposing LEDs. The additive effect can be controlled with the aspect ratio to provide uniform intensity level.
[0051]The light intensity as perceived in the lateral direction can be based on an incident angle 124. The incident angle 124 can be an angle measured between light traveling along a radiating direction 126 from one of the light sources 108 and the lens wall 110. Based on reflective and refractive characteristics of the inner filler 122, the lens wall 110, or a combination thereof, the light radiating through and out of the lens wall 110 from the light sources 108 can reduce as the incident angle 124 reduces. Further, light radiating through and out of the lens wall 110 can increase as the incident angle 124 increases, such as for a direct relationship between the incident angle 124 and the light intensity.
[0052]Referring now to FIG. 2, therein is shown a horizontal cross-sectional view of the electrical system 100 along a line 1-1 of FIG. 1. The electrical system 100 can include the lens wall 110 of FIG. 1, the inner filler 122 of FIG. 1, or a combination thereof corresponding to a cross-sectional shape of a circle or an ellipse, or an elliptical cross-section 202. The electrical system 100 can include the lens wall 110, the inner filler 122, or a combination thereof with a shape of a cylinder corresponding to circular or an elliptical cross-section along a horizontal plane.
[0053]The horizontal dimension 114 of FIG. 1 can correspond to a diameter or a length along an axis, such as a major or a minor axis. The line 2-2 for illustrating FIG. 1 can be coincident with the horizontal dimension 114.
[0054]The light sources 108 of FIG. 1 can be included within the cross-sectional shape of the lens wall 110, the inner filler 122, or a combination thereof. For illustrative purposes, the light sources 108 are shown having a shape or a cross section of a rectangular box. However, it is understood that the light sources 108 can correspond to many different shapes or cross-sections, such as circles, domes, any other polygon, cones or pyramids, equilateral or non-equilateral shapes, or a combination thereof.
[0055]Referring now to FIG. 3, therein is shown a further horizontal cross-sectional view of the electrical system 300 along a line similar to the line 1-1 of FIG. 1. In a further embodiment, the electrical system 300, similar to the electrical system 100 of FIG. 1, can correspond to a cross-sectional view different from FIG. 2.
[0056]The electrical system 300 can include the lens wall 110 of FIG. 1, the inner filler 122 of FIG. 1, or a combination thereof corresponding to a cross-sectional shape of a polygon. The electrical system 300 can include the lens wall 110, the inner filler 122, or a combination thereof with a shape of a column corresponding to a cross-section of a polygon, such as a triangle, a hexagon, or any other n-sided shape, along a horizontal plane. The electrical system 300 can include the lens wall 110, the inner filler 122, or a combination thereof corresponding to a polygonal cross-section 302.
[0057]The polygonal cross-section can correspond to an equilateral shape or a non-equilateral shape. The horizontal dimension 114 of FIG. 1 for the electrical system 300 can correspond to a length of one or more sides along the horizontal direction.
[0058]Referring now to FIG. 4, therein is shown a vertical cross-sectional view of the electrical system 400 along a line similar to the line 2-2 of FIG. 2 in a further embodiment of the present invention. The electrical system 400 can be similar to the electrical system 100 of FIG. 1 but for a lens wall 410, an inner filler 422, or a combination thereof.
[0059]The lens wall 410 can be similar to the lens wall 110 of FIG. 1, such as in material, connection, dimensions, function, horizontal cross-sectional shape, processing or manufacturing thereof, or a combination thereof as described above. The inner filler 422 can be similar to the inner filler 122 of FIG. 1 such as in material, connection, dimensions, function, horizontal cross-sectional shape, processing or manufacturing thereof, or a combination thereof as described above.
[0060]The lens wall 410, the inner filler 422, or a combination thereof can have a different vertical cross-sectional shape than in FIG. 1. The lens wall 410, the inner filler 422, or a combination thereof can extend at an angle toward the horizontal mid-region 116 of FIG. 1 in extending from the base structures 106 of FIG. 1 to the vertical mid-region 120 of FIG. 1 according to a concave cross-section 402, an angled-linear cross-section 403, or a combination thereof. The lens wall 410, the inner filler 422, or a combination thereof can be narrower around the vertical mid-region 120 than at end portions, such as a first end portion 430, a second end portion 432, or a combination thereof for opposing ends, such as for a distal end, a proximal end, or a combination thereof.
[0061]The first end portion 430, the second end portion 432, or a combination thereof of the inner filler 422, the lens wall 410, or a combination thereof can correspond to the portions thereof attached to the base structures 106, including or encapsulating the light sources 108 of FIG. 1, or a combination thereof. The lens wall 410, the inner filler 422, or a combination thereof can include the vertical cross-sectional shape with a taper near the vertical mid-region 120. The inner filler 422, the lens wall 410, or a combination thereof can include the horizontal dimension 114 of FIG. 1 less than or narrower at or near the vertical mid-region 120 than at the first end portion 430, the second end portion 432, or a combination thereof for the concave cross-section 402, the angled-linear cross-section 403, or a combination thereof.
[0062]For illustrative example, the lens wall 410, the inner filler 422, or a combination thereof are shown having the vertical cross-sectional shape with a smooth curved shape corresponding to the concave cross-section 402. However, it is understood that the lens wall 410, the inner filler 422, or a combination thereof can have the vertical cross-sectional shape corresponding to many different shapes, such as a continuous surface with multiple connected planar sections corresponding to the angled-linear cross-section 403 and exemplified by dotted lines for two planar sections joining at an angle.
[0063]The vertical cross-sectional shape can be characterized or represented by a shape measure 402. The shape measure 402 can include a distance, a focal point, or a combination thereof. For example, the shape measure 404 can include a focal point or a center point, as illustrated by ‘*’ in FIG. 4, for describing a shape or a rate of change in angle of orientation for a smooth curved surface corresponding to a parabolic or an arc-like cross-sectional shape. Also for example, the shape measure 404 can include a number of planar surfaces or a relative location and an angle between planar surfaces on the cross-sectional shape.
[0064]Also for example, the shape measure 404 can correspond to a distance along the horizontal direction between vertical lines matching outer most edge and inner most edge of the lens wall 410, the inner filler 422, or a combination thereof. As a more specific example, the shape measure 404 can correspond to a change in distance along the horizontal distance between a location where the lens wall 410, the inner filler 422, or a combination thereof contacts one of the base structures 106 and corresponding location at or on the vertical mid-region 120 as illustrated in FIG. 4.
[0065]It has been discovered that the concave cross-section 402 for the lens wall 410, the inner filler 422, or a combination thereof provides increased efficiency in generating the horizontal light intensity. The concave cross-section 402 can increase the incident angle 124 of FIG. 1 for light generated by the light sources 108 for locations on the lens wall 410 between the light sources 108 and vertical mid-region 120. The increase in the incident angle 124 can allow more light to transmit through the lens wall 410, the inner filler 422, or a combination thereof to provide the horizontal light intensity.
[0066]The electrical system 100 can include the lens wall 410, the inner filler 422, or a combination thereof with the concave cross-section 402 and the shape measure 404 configured to generate a target light intensity profile along the vertical dimension 118 of FIG. 1 with intensity levels corresponding to locations or points along the vertical dimension 118. The concave cross-section 402 and the shape measure 404 can be configured according to a color or a capacity of the light sources 108, the vertical dimension 118, the horizontal dimension 114, or a combination thereof.
[0067]Referring now to FIG. 5, therein is shown a vertical cross-sectional view of the electrical system 500 along a line similar to the line 2-2 of FIG. 2 in a further embodiment of the present invention. The electrical system 500 can be similar to the electrical system 100 of FIG. 1. For example, the electrical system 500 can include the light sources 108 of FIG. 1, the lens wall 110 of FIG. 1, the inner filler 122 of FIG. 1, or a combination thereof.
[0068]The electrical system 500 can include a first base structure 502, a second base structure 504, or a combination thereof corresponding to the base structures 106 of FIG. 1. The first base structure 502, the second base structure 504 can include instances of the base structures 106 including a base cavity 510 on a reference surface 512 therein.
[0069]The reference surface 512 can correspond to a surface on the base structures 106 facing or connected to the lens wall 110, the inner filler 122, or a combination thereof. The reference surface 512 can be planar, such as for substrates. For example, the reference surface 512 can be a bottom surface on the first base structure 502 located at the top of the electrical system 500 with the reference surface 512 facing the second base structure 504. Also for example, the reference surface 512 can be a top surface on the second base structure 504 located at the bottom of the electrical system 500 with the reference surface 512 facing the first base structure 502.
[0070]The base cavity 510 is a depression in the base structures 106. Vertical dimension, such as for a thickness, of the base structures 106 can be less in the base cavity 510 than outside of the base cavity 510. The base cavity 510 can be located relative to the horizontal mid-region 116 of FIG. 1. For example, the base cavity 510 can overlap or be centered on the horizontal mid-region 116.
[0071]The electrical system 500 can include the light sources 108 of FIG. 1 located within the base cavity 510. For example, light sources 108 can be attached to or integral with the base cavity 510. Also for example, the light sources 108 can be centered at or located about the horizontal mid-region 116.
[0072]The electrical system 500 can further include a substrate reflector 508 in the base cavity 510. The substrate reflector 508 is a reflective surface or a structure including the reflective surface on one or more of the base structures 106. The substrate reflector 508 can include reflective surfaces on or throughout the base cavity 510. The substrate reflector 508 can further include reflective surfaces horizontally surrounding the light sources 108.
[0073]The substrate reflector 508 can include a mirror, a reflective paint or coating, or a combination thereof on the base structures 106. The substrate reflector 508 can be on the base structures 106. For example, the substrate reflector 508 can be attached to one or more of the base structures 106 in the base cavity 510. Also for example, the substrate reflector 508 can be integral with the base cavity 510, the reference surface 512, or a combination thereof.
[0074]The electrical system 500 can further include one or more instances of a suspended reflector 514. The suspended reflector 514 is a structure with one or more reflective surfaces located within the inner filler 122 between the base structures 106. The suspended reflector 514 can be configured to reflect light generated or emitted by the light sources 108. The suspended reflector 514 can correspond to a shape, a size, a location, a relative arrangement, or a combination thereof specifically configured to reflect light in generating the target light intensity profile.
[0075]For example, the suspended reflector 514 can include a ball, a bead, a box, or a combination thereof. Also for example, the suspended reflector 514 can include a structure corresponding to a diamond or a conical shape. Also for example, the suspended reflector 514 can include a planar surface, a curved surface, angles or joints between surfaces with different orientations, or a combination thereof with reflective properties, such as utilizing a reflective coating or a material with reflective surface.
[0076]Also for example, the suspended reflector 514 can be affixed at a particular location within the inner filler 122 using a reflector stabilizer 516. The reflector stabilizer 516 is a connector configured to affix the reflector stabilizer 516 at a specific location relative to the inner filler 122, the light sources 108, the base structures 106, the lens wall 110, or a combination thereof, including a wire, a string, a frame, a lever or an extension, or a combination thereof. The reflector stabilizer 516 can be attached to or integral with the suspended reflector 514 along with one or more of the light sources 108, one or more of the base structures 106, the inner filler 122, the lens wall 110, a portion therein, or a combination thereof.
[0077]Also for example, the suspended reflector 514 can be affixed at a particular location relative to the light sources 108 by the inner filler 122. The inner filler 122 can be solid or become solid during manufacturing or processing. The suspended reflector 514 can be placed within the inner filler 122 at a specific location during manufacturing or processing to be encased or encapsulated by the inner filler 122 and affixed at the specific location.
[0078]The electrical system 100 can include the substrate reflector 508, the suspended reflector 514, or a combination thereof specifically configured to generate the target light intensity profile. For example, the substrate reflector 508, the suspended reflector 514, or a combination thereof can include a specific cross-sectional shape as represented by the shape measure 404 of FIG. 4.
[0079]For illustrative example, the substrate reflector 508 and the suspended reflector 514 are both shown with smooth curved surfaces corresponding to a concave depression or a convex surface for a curved reflective surface 540. The shape measure 404 can include a suspended reflector measure 520 for the suspended reflector 514, a substrate reflector measure 522 for the substrate reflector 508, or a combination thereof. For the curved reflective surface 540, the suspended reflector measure 520, the substrate reflector measure 522, or a combination thereof can include a coordinate or a relative location representing a focal point or region for light reflected from the substrate reflector 508, the suspended reflector 514, or a combination thereof.
[0080]Also for example, the suspended reflector 514 can be located at the specific location relative to the light sources 108, the horizontal dimension 114 of FIG. 1, the vertical dimension 118 of FIG. 1, or a combination thereof. As a more specific example, the suspended reflector 514 can be located at the vertical mid-region 120 of FIG. 1, the horizontal mid-region 116, at a location off-set from one or more mid-regions or edges of the inner filler 122, or a combination thereof. Also as a more specific example, a set of multiple suspended reflectors 514 can be located and arranged around the vertical mid-region 120, the horizontal mid-region 116, or a combination thereof.
[0081]It has been discovered that the suspended reflector 514 provides increased efficiency in generating light intensity. The suspended reflector 514 can reflect light from the light sources 108 to increase the incident angle 124 of FIG. 1. The suspended reflector 514 can reflect light radiating in certain directions to increase the incident angle 124, which can allow the reflected light to radiate through and past the lens wall 110. The increase in instances of the radiating direction 126 of FIG. 1 with sufficient instance of the incident angle 124 using the suspended reflector 514 can create brighter light intensity.
[0082]It has also been discovered that the suspended reflector 514 and the substrate reflector 508 together provide even more increased efficiency and uniform light intensity. The locations and shapes of the suspended reflector 514 and the substrate reflector 508 along with the aspect ratio can be configured to increase the radiating directions 126 with sufficient incident angle 124. Moreover, the locations and shapes of the suspended reflector 514 and the substrate reflector 508 can be used to control amount of light radiating through specific locations along the vertical dimension 118 to create the uniform intensity.
[0083]The suspended reflector 514, the substrate reflector 508, the aspect ratio, configurations thereof, or a combination thereof can be controlled during processing or manufacturing. For example, the electrical system 500 or a portion therein can be processed or manufactured with a 3-dimensional printer, which can control shape and locations in 3-dimensional space with precision control.
[0084]Referring now to FIG. 6, therein is shown a vertical cross-sectional view of the electrical system 600 along a line similar to the line 2-2 of FIG. 2 in a further embodiment of the present invention. The electrical system 500 can be similar to the electrical system 100 of FIG. 1, the electrical system 500 of FIG. 5, or a combination thereof.
