LOW PROFILE HOUSING KNOWLEDGE OF THE INVENTION Field of the Invention [001] The present invention in general relates to housings for electronic elements and / or devices, and more particularly low profile extrusions for electronic elements and / or devices that emit light.
Knowledge [002] In recent years, there have been dramatic improvements in the number and types of housing for light-emitting devices. The frequency with which housings for devices and / or chips mounted on circuit boards has also grown. Improvements in the housing for such devices have helped to advance the development of end products that incorporate assembled devices and can significantly reduce the cost and complexity of the product.
[003] Commonly, light emitting diodes (LEDs) mounted on circuit boards are the devices used within these improved housings. LEDs are solid-state devices that convert electrical energy into light, and generally comprise one or more active layers of semiconductor material sandwiched between opposing doped layers. When a slope is applied through the doped layers, holes and electrons are injected into the active layer where they recombine to generate light. Light is emitted from the active layer and from all surfaces of the LED.
[004] Developments in LED technology have resulted in devices that are brighter, more efficient and more reliable. LEDs have now been used in many applications that were previously in the field of incandescent fluorescence or neon lamps; some of these include exhibitors, shelf lighting, cooling lighting, oil canopy lighting, outdoor lighting, inlet lighting and any other application where lighting is desirable or can be
Petition 870190080320, of 08/19/2019, p. 6/59 / 37 required. As a result, LEDs mounted on circuit boards and / or other similar devices can be used in applications where they are subjected to environmental conditions that can degrade the device and adversely affect its functions and properties.
[005] U.S. Patent No. 4,439,818 to Scheib discloses a lighting strip that uses LEDs as light sources. The strip is flexible in three dimensions and is useful in training characters and is able to provide uniform illumination despite the characters selected for display. The strip comprises a flexible multilayer pressure sensitive adhesive tape, having a plurality of triangular notch sections on each side of the tape, with LEDs connected in series with a resistor. A disadvantage is that this arrangement is not durable enough to withstand conditions for outdoor use. The flexible tape and its adhesive can easily deteriorate when continuously exposed to the elements. Additionally, this strip cannot be cut to different lengths for different customized applications.
[006] U.S. Patent No. 5,559,681 to Duarte discloses a flexible self-adhesive light-emitting material that can be cut into at least two pieces. The light-emitting material includes a plurality of electrically coupled light-emitting devices such as light-emitting diodes. The material also includes electrical conductors to conduct electrical energy from an electrical energy source to each of the light-emitting devices. While this array of light can be cut to different lengths, it is not durable enough to withstand conditions of outdoor use. The flexible tape and its adhesive can easily deteriorate.
[007] LEDs have been used in perimeter lighting applications. PCT International Application PCT / AU98 / 00602 discloses perimeter light that uses LEDs as its light source and includes a light tube structure in which multiple LEDs are arranged inside a tube
Petition 870190080320, of 08/19/2019, p. 7/59 / 37 elongated translucent that diffuses or disperses the light from the LEDs. Perimeter light is used to highlight or decorate one or more features of a structure, such as a roof, window, door or corner edge between a wall and a roof section. This light fixture, however, cannot be cut to match the length of a building's structural functionality. Instead, perimeter lighting must be customized in order or is assembled without completely covering structural functionality. In addition, the light tube significantly attenuates the light emitted by its LEDs, significantly reducing the brightness of the light. Also, the light does not include a mechanism to compensate for expansion and contraction between adjacent lights.
[008] U.S. Patent No. 5,678,335 to Gomi et al. discloses a display device that has a plurality of light sources arranged along a display pattern to emit light from light sources. Each light source has a light-emitting diode (LED) in an open, elongated unit box. The box has a lens that disperses the light from the LEDs, at least in one direction along the length. The display pattern comprises a series of open slots with the light sources attached to the slots so that light sources can be illuminated to illuminate the display pattern.
[009] U.S. Patent No. 6,042,248 to Hannah et al., Discloses an LED frame for lighting signals that have a housing covered by a translucent panel. Each signal includes a plurality of accompanying impression at the base of its enclosure, with the impression running along the longitudinal axis of the enclosure. Linear arrays of LEDs that are mounted on printed circuit boards (PCBs), are mounted on the accompanying moldings. Each accompanying impression can hold two PCBs in parallel with each other from the PCBs arranged on a longitudinal edge with the LEDs pointing outwards.
Petition 870190080320, of 08/19/2019, p. 8/59 / 37 [0010] Different structures or housings can be used to hold electronic elements and / or devices that emit light, with some of these structures providing environmental protection for housed housings. Light from light-emitting devices can pass through surfaces in the housing, and certain materials actually reduce the efficiency of the light-emitting device by reflective / refractive light absorption. In addition, housing properties such as seams or lines in the manufacturing process can adversely affect the way in which the emitted light is released onto a surface being illuminated.
[0011] Caps can be included over different openings for the housing to completely attach the internal devices in order to further protect against the environment without interfering with the device's lighting applications. However, housings may differ slightly from each other as a result of the manufacturing process or they may fluctuate in size due to the heat produced from electronic elements, making covers unable to conform properly to the housing to provide adequate sealing. Additionally, cables for the housing may be required to enable the device to function. However, providing a hole in the housing or cover (s) for the cable to pass through can reduce the environmental protection provided by the housing.
SUMMARY OF THE INVENTION [0012] The present invention provides apparatus and methods of manufacturing low-profile extrusions for devices and / or electronic housing elements that emit light that allows improved light diffusion while increasing the environmental protection of the housed components, increasing the life of the hosted device, and reducing manufacturing costs and complexity. One embodiment provides a low profile housing comprising a housing with a first surface, a second surface substantially opposite the first surface, and at least one surface

DETAILED DESCRIPTION OF THE INVENTION [0043] The present invention provides apparatus and methods for manufacturing low profile housings for electronic devices, in particular low profile extrusions used for home light emitting devices. Some modalities are particularly applicable to homemade optoelectronic elements used in applications such as oil canopy lighting, shelf lighting, cooling lighting, exterior accent lighting, inlet lighting, display cabinets, magazine shelves, and any other application where linear lighting may be necessary. Optoelectronic elements can include one or more circuit boards with light emitting diodes (LEDs), solar cells, photodiodes, laser diodes, and other optoelectronic elements or combinations of optoelectronic elements. Preferred embodiments of the present invention are generally directed to housings that incorporate LEDs, but it is understood that the light-emitting devices discussed can also be used. Some exemplary types of accommodation are designed, at least in part, to effectively diffuse the emitted light and / or to project the light-emitting devices from environmental damage.
[0044] The housing is easy to manufacture, low cost, easy to use and assemble, and houses the light-emitting devices (s) in an aesthetically pleasing and accurate manner. He is also substantially of low profile such that the height of his body is short in comparison to the width and length of his body. Additionally, the housing is lightweight, can be customized to a variety of lengths and shapes, and particularly adapted to applications where linear lighting is desired or needed. It is understood, however, that the housing can be used for many different applications. Exemplary methods for fabricating the main body of such housings may include, for example, forming hollow housings using extrusion or double extrusion processes known in the art.
Petition 870190080320, of 08/19/2019, p. 14/59 / 37
However, it is understood that many other manufacturing processes can be used.
[0045] The housing may additionally comprise at least one end cap to protect the housed components and allow passage of a cable to the housing. This end cap can also provide ventilation or pressure equalization between the interior of the housing and the outside environment without allowing contaminants into the housing. The housing consists of a hollow center with an internal surface for holding light-emitting devices, or a substantially hollow center with an additional hollow extrudate inside it for holding light-emitting devices. The additional hollow inner or extruded surface is particularly adapted to hold printed circuit boards with LEDs, but it is understood that many other electronic devices and / or optoelectronic devices can be incorporated in the housing.
[0046] The present invention is described here with reference to certain modalities, but it is understood that the invention can be incorporated in many different ways and should not be understood as limited to the modalities defined here. In particular, the present invention is described below with respect to printed circuit boards housing with LEDs in a low profile extrudate with an end cap on both sides, but it is understood that the present invention can be used for housing many different devices in different ways.
[0047] It is also understood that when an element or functionality is referred to as being "in" another element or functionality, it can be directly in the other element or functionality or intervention elements can also be present. In addition, relative terms such as "internal", "external", "upper", "above", "lower", "below", and "below", and similar terms, can be used here to describe an element's relationship or functionality
Petition 870190080320, of 08/19/2019, p. 15/59 / 37 to another. It is understood that these terms are intended to involve different orientations of the accommodation and its components and contents in addition to the orientation represented in the figures.
[0048] Despite the terms first, second, etc. can be used here to describe various elements, components, features and / or sections, they should not be limited by these terms. These terms are used only to distinguish one element, component, functionality or section from another. Therefore, a first element, component, functionality, or section discussed below can be called a second element, component, functionality, or section without departing from the teachings of the present invention.
[0049] Modalities of the invention are described here with reference to illustrations which are schematic illustrations of idealized modalities of the invention. In this way, variations in the shapes of the illustrations as a result, for example, of manufacturing techniques and / or tolerances are expected. Modalities of the invention should not be interpreted as limited to the particular shapes of the regions illustrated here, but should include deviations in the shapes that result, for example, from manufacturing. The feature illustrated or described as square or rectangular may have rounded or curved features due to normal manufacturing tolerances. Thus, the features illustrated in the figures are not intended to illustrate the precise shape of a feature and are not intended to limit the scope of the invention.
[0050] FIG. 1 shows a side plan view of an embodiment of a low-profile extrudate 10 according to the present invention, which can be used to house one or more light-emitting devices, such as a printed circuit board with LEDs or double-sided printed circuit with LEDs. The low-profile extrudate 10 comprises an elongated housing 12, with the housing comprising a bottom surface
Petition 870190080320, of 08/19/2019, p. 16/59 / 37 supporting device 14, a top surface 16, first side surfaces 18a-18b, second side surfaces 20a-20b, and outer flanges 22a-22b.
[0051] As shown in FIG. 1, the housing in some embodiments may be generally rectangular in shape, with bottom surface 14 and top surface 16. However, the width 24 between first side surfaces 18a, 18b is greater than the width 26 between second side surfaces 20a , 20b. This creates heights 28a-28b, which are less than the height 30 between the bottom surface 14 and the top surface 16. When a light-emitting device such as a printed circuit board with LEDs is mounted inside the low profile extrudate 10, bottom surface 14 is positioned adjacent to the circuit board, with the circuit board at least partially held in place on both sides in the gaps created by heights 28a, 28b such that the light emitted from the LEDs emits away from the bottom surface 14. Alternatively, when a light-emitting device such as a double-sided printed circuit board (with LEDs on both sides) is positioned in the extrudate and held in position as described above, light emitted from the double-sided printed circuit board may emit both away from the bottom surface 14 and through the bottom surface 14. Double-sided printed circuit boards are discussed in more detail below. The low profile extrudate 10 can be configured in several other relevant ways without departing from the new aspects of the invention.
[0052] Although the circuit board can be held in position between the gaps created by heights 28a, 28b, the bottom surface 14 can provide a surface on which one or more electronic and / or optoelectronic devices such as printed circuit boards with LEDs can be additionally attached. Such a device can also be mounted and / or attached to the bottom surface 14 by welding, bonding, and / or any other relevant mounting method or combinations of methods.
Petition 870190080320, of 08/19/2019, p. 17/59 / 37 [0053] Frame 12 is preferably made of a substantially clear material, although it is understood that materials with similar properties can also be used. Light diffusers such as dispersion particles (eg titanium oxides) or calcium carbonate can be added to the housing material 12 during the extrusion process to help resolve machining and extrusion process lines and marks and assist in diffusive properties of the housing 12. In addition to maximizing the diffusive properties of the housing 12, the end of the surface should be as smooth as possible and the hatched area within the top surface 16 must be substantially free of machining lines and marks from the extrusion process on both the inner and outer surfaces. If a double-sided printed circuit board is used, then most of the bottom surface 14 must also be substantially free of lines and machining marks from the extrusion process in order to maximize the diffusive properties of the housing. The diffusive properties of the housing allow the light sources on the circuit board to appear as a continuous light source when they emit light.
[0054] As a result of the low profile shape of the housing 12, the outer ends preferably comprise a surface area that is minimized when compared to the surface area along the length of the housing 12. This allows the ends to be sealed more easily and efficiently than a housing with a comparatively larger surface area in its sealing portion, while reducing the possibility that any external environmental contaminants could infiltrate the housing.
[0055] The dimensions of the low-profile extrudate 10 may depend on the one or more electronic and / or optoelectronic devices anticipated to be housed inside, the expected implementation of the extrudate 10 and its components, the amount of light to be dissipated by the device, and /or others
Petition 870190080320, of 08/19/2019, p. 18/59 / 37 factors. For example, according to one embodiment, the approximate dimensions of the extrudate 10 may include a height from the bottom of the surface 14 to the top of the surface 16 of 0.300 inches (0.762 cm), a surface thickness 16 of 0.500 inch (1) , 27 cm), a width 26 measuring 0.550 inches (1.397 cm), an hatched section width measuring 0.5 inch (1.27 cm), a width 24 of 0.650 inches (1.65 cm), heights 28a, 28b 0.080 inch (0.203 cm), a height 30 of 0.200 inch (0.508 cm), a width between the outermost portions of flanges 22a, 22b of 0.890 inch (2.261 cm), a height of flanges 22a, 22b of 0.030 inch ( 0.076 cm), and a height from the bottom of surface 14 to the top of flanges 22a, 22b of 0.080 inch (0.0203 cm) +/- 0.015 inch (0.038 cm). Extruded 10 can be cut to any variety of lengths depending on the intended use.
[0056] FIGS. 2 to 5 represent various embodiments of a mounting clip for mounting the low profile extrudate 10 shown in FIG. 1. While FIGs. 2 to 5 represent some exemplary methods for clips used to mount the extrudate 10, it is understood that any number of mounting methods can be used, including, for example, tracking systems, double-sided tape, surface bonding, or simple positioning in a support surface.
[0057] FIG. 2 shows a top view of the mounting clip 32 according to an embodiment of the present invention. FIG. 3 is a side plane view of a low profile extrudate 10 supported within the mounting clip 32. The mounting clip 32 comprises a substantially flat surface 40 from which projections 36a, 36b extend substantially perpendicularly. Edges 34a, 34b extend perpendicularly from the projections 36a, 36b and are substantially parallel to the flat surface 40. The hole 38 passes through the second surface 42, which is an extension of the flat surface 40 which extends to the right of the projection
Petition 870190080320, of 08/19/2019, p. 19/59 / 37
36b.
[0058] An outer side of surface 42 may come into contact with an external mounting surface (not shown) such that surface 40 can extend beyond the external mounting surface. Alternatively, portions of both surfaces 40 and 42 may come into contact with an external mounting surface such that projections 36a, 36b extend away from the external mounting surface, although it is understood that there are any number of arrangements that may occur with relation to the external mounting surface. A screw, nail, post or the like can be passed through hole 38 to connect the mounting clip 32 to an external surface.
[0059] The projections 36a, 36b are adjacent to the outermost surface of flanges 22a, 22b, while flanges 34a, 34b extend over the top of flanges 22a, 22b to hold the extrudate 10 in place. It is understood that the mounting clip 32 can be made of a variety of materials, such as plastic, acrylic, metal or any suitable material. Depending on the material characteristics of the mounting clip 32, the extrudate 10 can either be thrown into place between the ridges 36a, 36b and edges 34a, 34b or slid into place along the flat surface 40 and between the ridges 36a, 36b and edges 34a, 34b. For example, if the mounting clip 32 is made of flexible metal or plastic, flanges 22a, 22b can be pressed against edges 34a, 34b to cause the projections 36a, 36b to extend outward such that the extrudate 10 can be pushed into place. The flexible nature of the material will cause the projections 36a, 36b and edges 34a, 34b to return to their original position and secure the projection 10. Alternatively, the projection 10 can be slid into place despite the material characteristics of the mounting clip 32.
[0060] FIG. 4 is a perspective view of another embodiment of an assembly clip in accordance with the present invention. The clip
Petition 870190080320, of 08/19/2019, p. 20/59 / 37 assembly 44 comprises a substantially flat surface 48 from which lower edge 52 and raised surface 54 extend. Upper curved arm 46 extends away from surface 54 and towards lower edge 52, with upper edge 50 extending downwardly from the outer end of arm 46. Nut 56 is adjacent to arm 46 on surface 54. The hole 58 passes through nut 56 and surface 54.
[0061] An external side of the surface 54 can come into contact with an external mounting surface (not shown) such that the surface 48 can extend beyond the external mounting surface. Alternatively, portions of both surfaces 48 and 54 may come into contact with an external mounting surface such that the arm 46 extends away from the external mounting surface, although it is understood that there are any number of arrangements that may occur with respect to to an external mounting surface. Nut 56 may include threading along the circumference of hole 58 such that a correspondingly threaded screw (not shown) can be placed in hole 58 and nut 56 can be tightened to secure clip 44 to an external mounting surface. However, nut 56 is not required and it is understood that a nail, post or the like can be passed through hole 58 to connect the mounting clip 44 to an external surface.
[0062] The arm 46, the surface 48, and edges 50, 52 work together to wrap the extrudate 10 and secure it in place. It is understood that the mounting clip 44 can be made of a variety of materials, such as plastic, acrylic, metal, or any suitable materials. If the material has flexible characteristics, extruded can be stuck in place between arm 36, surface 48 and edges 50, 52.
[0063] FIG. 5 is a perspective view of an embodiment of an assembly clip according to the present invention, which is a variation of the clip 32 shown in FIGS. 2 and 3. The mounting clip 60 comprises
Petition 870190080320, of 08/19/2019, p. 21/59 / 37 a substantially flat surface 62 from which projections 64, 66 extend substantially perpendicularly. Flanges 68, 70 extend perpendicularly from projections 64, 66 and are substantially parallel to flat surface 62. Nut 72 is on the second surface 72, which is an extension of flat surface 62 that extends to the left of projection 64. Hole 76 passes through nut 74 and surface 72.
[0064] An outer surface 72 may come into contact with an outer mounting surface (not shown) such that surface 62 may extend beyond the outer mounting surface. Alternatively, portions of both surfaces 62 and 72 may come into contact with an external mounting surface such that projections 64, 66 extend away from the external mounting surface, although it is understood that there are any number of arrangements that may occur with relation to the external mounting surface. Nut 74 can include threading along the circumference of hole 76 such that a corresponding threaded screw (not shown) can be placed in hole 76 and nut 74 can be tightened to secure clip 60 to an external mounting surface. However, nut 74 is not required and it is understood that a nail, post or the like can be passed through hole 76 to connect the mounting clip 60 to an external surface.
[0065] The projections 64, 66 are adjacent to the outermost surface of flanges 22a, 22b, while edges 68, 70 extend over the top of flanges 22a, 22b to hold the extrudate 10 in place. It is understood that the mounting clip 60 can be made of a variety of materials, such as plastic, acrylic, metal or any suitable material. Depending on the material characteristics of the mounting clip 60, the extrudate 10 can either be played at the location between the projections 64, 66 and edges 68, 70 or slid into place along the flat surface 62 and between the projections 64, 66 and edges 68, 70.
Petition 870190080320, of 08/19/2019, p. 22/59 / 37 [0066] The dimensions of a mounting clip according to the present invention may depend on the dimensions of the extrudate 10, the type of mounting clip being used, and / or other similar factors. For example, according to a modality with characteristics similar to the mounting clip 32, the approximate dimensions are as follows: a surface width 40, 42 of 0.500 inch (1.27 cm), a hole diameter 38 of 0.160 inch ( 0.406 cm), a surface length 40 of 1,000 inch (2.54 cm), a surface length 42 of 0.375 inch (0.952 cm), a projection height 36a, 36b of 0.240 inch (0.061 cm), a height of surfaces 40, 42 of 0.060 inch (0.152 cm), and a border width 34a, 34b of 0.105 inch (0.267 cm).
[0067] FIGS. 6 to 9 represent a surface cover 78 according to some embodiments. End cap 78 is designed to seal at least one end of extrudate 10 in order to protect the housed device against environmental conditions such as moisture. End caps according to the present invention are constructed, at least in part, of a substantially soft and flexible material that can withstand thermal emissions from the housed device and variations in the extrudate that result from the manufacturing process. The end cap is also preferably formed of a material that is resistant to water and other environmental conditions that could otherwise seep into the housing. A suitable material is silicone, but it is understood that other relevant materials can be used.
[0068] End cap 78 includes an inner cap section 80, outer cap section 82, first bonding surface 84 (shown with dashed lines), second bonding surface 86 (shown by shading), inner flanges 88a, 88b, and outer flanges 90a, 90b. The inner cover section 80 is designed to fit within at least one end of the extrudate 10, with the first connecting surface 84
Petition 870190080320, of 08/19/2019, p. 23/59 / 37 coupled with internal flanges 88a, 88b measured to narrowly fit within an internal portion of at least one end of the extrudate 10 and the gaps caused by heights 28a, 28b, respectively. The outer cover section 82 is designed to fit externally to at least one end of the extrudate 10, with outer flanges 90a, 90b shaped and measured to generally correspond to flanges 22a, 22b. The outer cover section 82 is additionally preferably measured to be slightly larger than the outer portion of at least one end of the extrudate 10, such that the connecting surface 86 can compensate for any changes in the extrudate 10 caused by manufacturing variations and / or thermal expansion. While the end cap 78 is represented as having a generally rectangular shape with flanges to conform to a generally rectangular end with flanges of the extrudate 10, it is understood that the end cap 78 can be configured in any number of relevant ways, such as a square, rectangle, or oval.
[0069] When the end cap 78 is positioned on at least one end of the extrudate 10, the first connection surface 84 is fitted close to the inside of an end of the extrudate and connected using an adhesive surface along 84 and the corresponding portion of inner end of extrudate 10. While any number of adhesives can be used, a preferred adhesive will be thermally resistive and will seal the extrudate from environmental conditions such as moisture. Similarly, the second bonding surface 86 is bonded to the outer surface of at least one extrudate 10 using an appropriate adhesive.
[0070] In other embodiments, the end cap 78 may include a ventilation feature 210 to allow pressure equalization inside and outside the extrudate. This ventilation feature 210 allows pressure equalization to take account of pressure differences caused by high altitude and extremely hot environmental conditions.
Petition 870190080320, of 08/19/2019, p. 24/59 / 37
The ventilation feature 210 allows two-way transfer of air, but does not allow contaminants, such as moisture, in the extrudate. In one embodiment, the ventilation functionality 210 can be achieved by using at least one ventilation hole 210 in the end cap which may be small enough to allow air transfer, but not allow the transfer of contaminants such as moisture. For example, according to one embodiment, the ventilation hole 210 may be 0.013 inches (0.033 cm) in diameter, large enough to allow air transfer while still small enough that the surface tension of water prevents moisture from entering the air. ventilation hole 210. The dimensions of a lid end ventilation hole 210 according to the present invention may vary depending on the dimensions of the extrudate / housing, materials used, and / or other relevant factors.
[0071] In another embodiment, to provide ventilation at least a portion of end cap 78 may comprise a material that allows two-way transfer of air without allowing contaminants such as water to enter the extrudate. This material can be Gore Tex or silicone, but other suitable materials can also be used. In yet another embodiment, a valve can be positioned on end cap 78 to achieve this ventilation without allowing contaminants in the extrusion. These ventilation features can be used in both single and double extrusion modes.
[0072] FIGS. 10 to 14 represent an alternative end cap 92 according to some embodiments. End cap 92 is designed to seal at least one end of extrudate 10 in order to protect the housed device against environmental conditions such as humidity. End cap 92 is constructed of the same material as end cap 78.
[0073] End cap 92 includes inner cap sections 94a,
Petition 870190080320, of 08/19/2019, p. 25/59 / 37
94b, outer cover section 96, first bond surfaces 98a, 98b (shown by dashed lines), second bond surface 100 (shown by shading), inner flanges 102a, 102b, outer flanges 104a, 104b, and hollow hole 106 Inner cover sections 94a, 94b are designed to fit within at least one end of extrudate 10, with first bond surfaces 98a, 98b coupled with inner flanges 102a, 102b to narrowly fit within an inner portion of at least one extrudate end 10 and gaps caused by heights 28a, 28b, respectively. The outer cap section 96 is designed to fit externally to at least one end of the extrudate 10, with outer flanges 104a, 104b shaped and measured to generally correspond to flanges 22a, 22b as shown in FIGS. 1 and 3. The outer cap section 96 is additionally preferably measured to be slightly larger than the outer portion of at least one end of the extrudate 10, such that the connecting surface 100 can compensate for any changes in the extrudate 10 caused by manufacturing variations and / or thermal expansion. End cap 92 may also include the ventilation features discussed above and shown in FIGs. 6 to 9. [0074] Hole 106 is provided in the middle of end cap 92 such that a cable (not shown) can be passed through to supply power to the housed device. The diameter of hole 106 is smaller than the diameter of the cable such that when the cable is inserted into hole 96, the hole stretches around the cable creating a seal between the two to prevent environmental contaminants from infiltrating inside the extrudate 10 While the end cap 92 is represented as having a generally rectangular shape with flanges to conform to a generally rectangular end with extruded flanges 10, it is understood that the end cap can be configured in any number of relevant ways, such as a square, rectangle, or oval.
Petition 870190080320, of 08/19/2019, p. 26/59 / 37 [0075] When end cap 92 is positioned on at least one end of extrudate 10, first bond surfaces 98a, 98b are fitted close to the inside of an extrudate end and bonded using an adhesive as described above . Similarly, the second bond surface 100 is bonded to the outer surface of at least one end of extrudate 10 using an appropriate adhesive.
[0076] The dimensions of an end cap according to the present invention may vary depending on the dimensions of the extrudate / housing, whether a cable is to be passed through, and / or other relevant factors. For example, in some embodiments of an end cap as shown in FIGs. 7 to 10, the dimensions can be as follows: a section height of 0.320 inch (0.813 cm), a height of outer flanges 90a, 90b of 0.100 inch (0.254 cm), a section top portion width of 82 0.770 inch (1.956 cm), a width from the outer edge of flange 90a to the outer edge of flange 90b of 0.910 inch (2.311 cm), a width of the top section section of 0.530 inch (1.346 cm), a width from the outer edge of flange 88a to the outer edge of flange 88b of 0.630 inch (1.6 cm), a section thickness 82 of 0.188 inch (0.478 cm), and a section thickness 80 of 0.063 inch (0 , 16 cm). An end cap according to the alternative embodiment of FIGs. 11 to 14 may have dimensions similar to the end cap as described above, but with the hollow hole 106 having a diameter of 0.156 inch (0.396 cm) which is slightly smaller than the diameter of a cable that runs through said hole.
[0077] FIG. 15 represents a plurality of connected light-emitting devices 110 with three low-profile extrusions 10 in a chain chain. While there are three extrusions 10 connected in this application, it is understood that any number of extrusions can be connected in various configurations. End caps 92 are provided on the
Petition 870190080320, of 08/19/2019, p. 27/59 / 37 extrusion ends 10 to allow wire (s) 112 to pass through and / or between extrusions 10 and end caps 92. A power device (not shown) is connected to wire 112 to supply power to the connected devices 110. It is understood that end caps 92 can be provided wherever a thread into and out of the extrudate is desired. The end cap 78 is provided at the end of the extrudate 10 to the far right as said extrusion is at the end of the chain in current. It is understood that end cap 78 can be provided at any end where a thread 112 is not desired.
[0078] FIG. 16 depicts a shelf unit 114 using two connected devices 110 shown in FIG. 15. Devices 110 are mounted and maintained in low profile on the surfaces on the two shelves in unit 114 such that devices 110 are like leveling for their mounting surfaces. Devices 110 are assembled and secured using any of the mounting means (not shown) as described above. Devices 110 are positioned such that light will diffuse out and down over any object positioned on the shelves.
[0079] FIG. 17 shows an end view of another embodiment of a low-profile extrudate 120 according to the present invention that can be used to house one or more light-emitting devices, such as printed circuit boards with LEDs or a double printed circuit board face with LEDs on both sides. The low profile extrudate 120 comprises an elongated housing 122, with the housing comprising a rounded bottom surface 124, a top surface 126, angled side surfaces 128a-128b, second side surfaces 130a-130b, and external curved extensions 132a- 132b. Additionally, the extrudate 120 comprises a second integral extrudate 134 inside the top surface 126, with the second extrudate 134 comprising a
Petition 870190080320, of 08/19/2019, p. 28/59 / 37 elongated housing 136, with the housing comprising a bottom surface 138, side surfaces 140a-140b, and top surface 142 through top surface 126.
[0080] The second extrudate 134 can be coextruded with extrudate 120, using double extrusion methods well known in the art. Alternatively, extrudate 120 and second extrudate 134 can be extruded separately, and adjusted together in a later manufacturing step. In one embodiment, the second extrudate 134 is provided to house a printed circuit board with LEDs, while the extrudate 120 is provided to surround the second extrudate 134 and assist, for example, in improving the light emitted from the LEDs.
[0081] As shown in FIG. 17, the housing 136 of the second extrudate 134 may be generally rectangular in shape, with the bottom surface 138 opposite the top surface 142 and the side surface 140a opposite to the side surface 140b. However, it is understood that the extrudate 134 can be configured in several other relevant ways without departing from the new aspects of the invention. When a light-emitting device such as a printed circuit board with LEDs is mounted inside the extrudate 134, the circuit board is at least partially held in position by a close fit between side surfaces 142a-142b. In addition, side surfaces 142a-142b can be arranged at a slight angle, such that the distance between them narrows towards the top surface 142 (or vice versa). This narrowing is another way of creating a tight fit between the interior of the extrudate 134 and a printed circuit board, which can also work to hold the circuit board in place. Although a circuit board can be held in place between side surfaces 140a-140b as described above, it can also be mounted and / or secured to extrudate 134 by welding, bonding, and / or any other relevant mounting method or combinations of methods.
Petition 870190080320, of 08/19/2019, p. 29/59 / 37 [0082] When a light-emitting device such as a double-sided printed circuit board is positioned in the extruded and held in place as described above, light emitted from the double-sided printed circuit board can emit either through the bottom surface 138 and through top surface 142. Alternatively, if a double-sided printed circuit board is positioned in the extrudate, it can be configured to emit light through both bottom surface 138 and top surface 142. In addition , two double-sided printed circuit boards can be used and configured from the back such that light is emitted through both bottom surface 138 and top surface 142.
[0083] The housing 136 of extrudate 134 is preferably made of a substantially clear material with light diffusing properties such as acrylic, although it is understood that other materials with similar properties can also be used. In addition, it is understood that the housing 136 can be comprised of materials of varying colors, despite the use of an unclear material absorbing more emitted light than a clear material. Light diffusers such as dispersion particles (eg, titanium oxides) or calcium carbonate can be added to housing material 136 during the extrusion process to help resolve extrusion process machining lines and marks and assist diffusive properties of frame 136, the surface end should be as smooth as possible and also free of lines and machining marks from the extrusion process at both its inner and outer ends. The diffusive properties of the housing allow the light sources on the circuit board to appear as a continuous light source when they emit light.
[0084] The housing 122 of the extrudate 120 is preferably made of a colored material such as a light-permeable plastic, with the plastic capable of further diffusing the light emitted through the bottom surface 138 of the second extrudate 134. However, it is understood that other materials with
Petition 870190080320, of 08/19/2019, p. 30/59 / 37 similar properties can also be used according to the present invention. In addition, the shape of the housing 122 can provide desired light scattering effects, with the shape being customizable to provide a variety of desired light scattering effects. For example, in a possible embodiment, the housing 122 can be shaped as shown in FIG. 17 and comprised of a red light-permeable plastic. Light emitted from the bottom surface 138 of the extrudate 134 will be diffused by red plastic, such that the housing 122 will emit a substantially red mold. In embodiments where a double-sided printed circuit board is fitted to the second extrudate 134, light emitted from the other side of the circuit board will be diffused through the top surface 142 of the second extrudate 134, such that the top surface 142 will emit white light or any color light emitted from the LEDs if the second extrudate is comprised of a substantially clear or matte material. It is understood that any color can be used for frame 122, and that the LEDs on a single or double-sided printed circuit board can emit any color or combination of colors to result in the desired effect.
[0085] The dimensions and shape of extrusions 120, 134 may depend on the electronic and / or optoelectronic devices anticipated to be housed within the second extrudate 134, the expected implementation of extrudate 120 and its components, the amount of light to be dissipated by the device , and / or other factors. Extrusions 120, 134 can be cut to any variety of lengths depending on the intended use. In addition, multiple extrudates 120 can be stranded together as discussed in more detail below.
[0086] FIG. 18 is an exploded view of one end of the extrudate 120. As shown, the double-sided printed circuit board 144 is slid into the second extrudate 134, where it will maintain a tight fit within the extrudate 134 through close measurements or other means of
Petition 870190080320, of 08/19/2019, p. 31/59 / 37 hold it in position as discussed above. The circuit board side 144 facing upwards will have a plurality of light emitting devices (not shown) that will emit light through the top surface 142 of the second extrudate 134. As seen in FIG. 18, the top surface 142 is more clearly differentiated from the top surface 126 of housing 122. The top surface 142 is preferably either clear or matte, and comprised of a material that substantially diffuses the light from the light emitting devices such that they they look like a continuous light source. In addition, light emitted from light emitting devices on the top surface of circuit board 144 is preferably transmitted through top surface 142 such that the same wavelength emitted from light emitting devices is emitted from of the surface 142. For example, if the light-emitting devices on the top surface of circuit board 144 emit yellow light, then the clear or matte nature of the top surface 142 will allow yellow light to be transmitted from it. However, it is understood that any other color or combination of colors can be transmitted through said top surface 142.
[0087] The light emitted from the light emitting devices on the bottom surface of the circuit board 144 will be transmitted through the light or matte bottom surface 138 of the second extrudate 134 such that substantially the same wavelength emitted from the light emitting devices light will be transmitted through surface 138. However, once the light reaches and passes through the surfaces of the housing 122, the color of the light emitted from the housing 122 will depend on what color the housing 122 is. For example, if housing 122 is transparent red and the light-emitting devices on the bottom surface of circuit board 144 emit white or red light, then the light emitted from housing 122 will be substantially red. However, it is understood that any other color or combination of colors can be transmitted outside the housing 122.
Petition 870190080320, of 08/19/2019, p. 32/59 / 37 [0088] Since the plate 144 is fitted to the second extrudate 134, an end cap 146 can be fitted to the end of extrudate 134 to seal the end and protect the electronic elements from environmental elements. The end cap 146 may be substantially similar to the modalities discussed with respect to the low profile extrudate 10, or it may comprise a simpler rectangular shape as shown in FIG. 18 such that the end cap 146 acts as a simple plug to seal the end of extrudate 134, and is preferably formed of silicone. However, it is understood that other suitable materials can also be used. The end cap 146 can also comprise a hole 148, provided that a wire 150 is used to energize electronic elements of the circuit board 144 can pass out of the extrudate 134 once it is sealed by the end cap 146.
[0089] Since the second extrudate 134 is sealed by the end cap 146, the extrudate 120 can be sealed using end cap 152. As shown in FIGs. 18, 19a-19b, and 20a-20b, the end cap 152 is substantially the same shape as the end of the extrudate 120. The end cap 152 is preferably made of the same material and color as the extrudate 120, with plastic or other suitable materials applicable in accordance with the present invention. On the side of the end cap 152 facing away from the extrudate 120, a locking fin 154 and a groove 155 below the fin 154 are provided. When adjacent extrusions 120 are brought into contact one after the other, the locking fin of an end cap 152 fits into the groove 155 of an adjacent end cap 152. The locking fin arrangement 154 and the groove 155 is important as it allows movement between adjacent extrusions 120 that can occur for a variety of reasons, such as expansion and / or contractions of extrusions 120 from variances of
Petition 870190080320, of 08/19/2019, p. 33/59 / 37 temperature. These variances can be caused by the heating and cooling of electronic elements mounted within extrusions 120 or can be the result of changes in ambient temperature.
[0090] In other embodiments, the cap end 152 may include a venting feature 210 to allow pressure equalization inside and outside the extrudate similar to the same feature shown in FIG. 6 to 9 and described above. This ventilation feature 210 could allow two-way transfer of air, but it cannot allow contaminants, such as moisture, in the extrudate. In one embodiment, the ventilation functionality 210 can be achieved by using at least one ventilation hole 210 in the end cap which may be small enough to allow air transfer, but not the transfer of contaminants such as moisture. For example, according to one embodiment, the ventilation hole 210 can be 0.013 inches (0.033 cm) in diameter, large enough to allow air transfer while remaining small enough so that the surface tension of water prevents moisture from entering. in the ventilation hole 210. The dimensions of an end cap ventilation hole 210 according to the present invention may vary depending on the dimensions of the extrudate / housing, materials used, and / or other relevant factors.
[0091] In another embodiment, to provide ventilation at least a portion of the end cap 152 may comprise a material that allows two-way transfer of air without allowing contaminants such as water to enter the extrusion. This material can be Gore Tex or silicone, but other suitable materials can also be used. In yet another embodiment, a valve can be positioned on end cap 152 to achieve this ventilation without allowing contaminants within the extrudate. These ventilation features can be used in both single and double extrusion modes.
Petition 870190080320, of 08/19/2019, p. 34/59 / 37 [0092] On the side of the end cap 152 facing towards the extrudate 120, a generally perpendicular flange 156 with a central groove is provided. Surrounding the flange 156 is an inner surface 158 of end cap 152, which rests against the end of the extrudate 120. A gasket 160 is also provided, which is adapted to fit comfortably between flange 156 and the extrudate rope 120. A gasket 160 is preferably made of silicone, although it is understood that other suitable materials can also be used. As shown in FIGs. 19a and 19b, flange 161 on gasket 160 is designed to fit grooved flanges 156. An adhesive is preferably applied to surfaces 166 (see FIG. 19b), and then equal pressure is applied to gasket 160 to allow it to adjust comfortably on the grooved flange 156 by perpendicular force. FIG. 20a and 20b show gasket 160 firmly attached to an end cap 152 through grooved flange 156. Since gasket 160 and end cap 152 are securely attached, end cap 152 can be positioned at the extruded end 120, with the gasket providing a seal on the extrudate 120 against water and other environmental elements that can damage the electronic components inside the extrudate. In addition, end cap 152 and integrated gasket 160 can also help to compensate for variances in extrudate 120 of the extrusion process. An adhesive can also be applied along surface 158 to provide additional sealing between the inside of end cap 152 and extrudate end 120. An adhesive like Weld-On® can be advantageously used to provide a substantially molten seal, but it is understood that other adhesives are also suitable according to the present invention.
[0093] The end cap 152 additionally comprises a rectangular notched portion of grooved flange 156 as well as surface
Petition 870190080320, of 08/19/2019, p. 35/59 / 37 rectangular 162 designed to fit the end of and around the second extrudate 134. Hole 164 is provided to accept wire 150, which is passed through end cap hole 148 and then to hole 164. While end cap 152 and gasket 160 provide a means of sealing the end of extrudate 120, it is understood that suitable end caps, gaskets, plugs, or other suitable sealing methods can also be used in accordance with the present invention. End cap 152 may also include ventilation as described above.
[0094] FIGS. 21, 22a, and 22b represent an embodiment of a mounting bracket for mounting the extrudate 120 shown in FIG. 17. While FIGs. 21, 22a, and 22b represent an exemplary method for a support used to assemble the extrudate 120, it is understood that any number of assembly methods can be used, including, for example, tracking systems, double-sided tape, surface bonding, or simple placement on a support surface.
[0095] FIG. 21 shows a perspective view of the mounting bracket 170 according to an embodiment of the present invention. The mounting bracket 170 comprises a slightly curved and angled trunk portion 172 protruding from the base portion 176. The base portion 176 further comprises a flange 178, designed to slide in and under the outer curved extension 132b. The base portion 176 further comprises a flange 180, with a lower extended portion 184 designed to slide under the outer curved extension 132a when the screw 182 is tightened. As best shown in FIG. 22a, mounting bracket 170 is positioned between external curved extensions 132a and 132b, with flange 178 sliding under extension 132b, and flange 180 resting on top of extension 132a before screw 182 secures mounting bracket 170 to extruded 120. As shown in FIG. 22b, the
Petition 870190080320, of 08/19/2019, p. 36/59 / 37 screw 182 can be tightened, which causes the substantially L-shaped portion 185 to move towards the outer curved extension 132a, such that it causes the flange 184 to slide under the extension 132a and secure the support mounting bracket 170 to extrudate 120. Alternatively, mounting bracket 170 can be preconfigured such that the flange is extended, and then bracket 170 can be slid into position between extensions 132a, 132b from one end of extruded 120.
[0096] Mounting bracket 170 additionally comprises mounting holes 174 along the opposite surface 175 of trunk 172 from base portion 176. Mounting holes 174 are provided such that mounting bracket 170 can be attached to an external surface, such as a building, which is intended to be illuminated by the extrudate 120. Screws, nails, posts or the like can be passed through holes 174 to connect mounting brackets 170 to a desired external surface. The mounting bracket 170 can be made of a variety of materials, such as plastic, acrylic, metal or other suitable materials.
[0097] The dimensions of the mounting bracket 170 may depend on the dimensions of the extrudate 120, the type of surface extrudate 120 must be mounted on the desired lighting effects to be provided by the extrudate 120, and / or such other factors. For example, according to an embodiment of the present invention, the trunk 172 of the mounting bracket 170 can be approximately 6 inches (15.24 cm) long, which allows the extrudate 120 to stand outside the outer surface such that light emitted from the top surface of the extrudate 134 can essentially act as a backlight when the extrudate 120 is mounted. However, it is understood that other mounting support dimensions 170 are also acceptable in accordance with the present invention.
[0098] FIGs. 23 and 24 represent a double-sided circuit board 144 with light emitting devices on both sides according to a
Petition 870190080320, of 08/19/2019, p. 37/59 / 37 embodiment of the present invention. FIG. 23 represents the top surface 186 of circuit board 144, which preferably comprises a plurality of LEDs 188 along its length. However, it is understood that other suitable light-emitting devices can also be used in accordance with the present invention. 188 LEDs can be incorporated to emit any color or combination of colors according to the desired emission effects. For example, in an embodiment according to the present invention, LEDs 188 can be adapted to emit yellow light. The top surface 186 of the circuit board 144 is the side facing towards the top surface 142 of the second extrudate 134 (or alternatively, the top surface 16 of the extrudate 10). If the extrudate 134 (or extrudate 10) is comprised of a clear or matte material, the light emitted from the top surface will appear substantially yellow. Alternatively, if other colors or color combinations are emitted from LEDs 188, the color emitted from the light or matte top surface of extrusions 10 or 134 will be substantially the same as that emitted from LEDs 188.
[0099] Black lines 190 on the top and bottom surfaces of the double-sided circuit board 144 represent the locations where circuit board 144 can be cut along its length without cutting the underlying drive circuit assembly. Thus, the length of the circuit board 144 can be readily customized in place to conform to any desired length as required by the outer surface of the extrudate 10 or 120 which must be mounted. In addition, circuit board 144 can be readily cut when it is installed inside extrudate 10 or second extrudate 134, provided that extrusions 10, 134 are comprised of a substantially transparent material such that black lines 190 are visible through them. In this way, extrusions 10, 134 and circuit board 144 can be cut in place simultaneously, which
Petition 870190080320, of 08/19/2019, p. 38/59 / 37 can reduce the steps required to provide a customized final product. Any device or tool can be used to cut circuit board 144 along black lines 190 and the corresponding extrudate, including knives, saws, blades, lasers, etc. Alternatively, the cuttable circuit board 144 can be separated from an adjacent portion by snapping, flexing, folding or other similar movement.
[00100] An important aspect of the cuttable circuit board 144 is that electronic elements of the separate portions that remain after a cut are fully functional without the need for any complicated refining. To enable such fully functional cutting portions, circuits that can be cut underlying must be provided on circuit board 144. Suitable modalities of circuits that can be cut are described in Patent Application Serial No. 12/321, 422 by the same inventors and attorney for the present invention, which is incorporated herein by reference. It is understood that single or double-sided cuttable circuit boards can be provided in accordance with the present invention. In addition, circuit boards can be segmented into several portions along their length such that the segments can essentially be folded over one another; this allows the segmentation of the circuit boards, which on the other hand can be quite substantial in length, to be folded and compressed for shipment.
[00101] FIG. 24 represents the bottom surface 194 of circuit board 144, which preferably comprises a plurality of LEDs 196 along its length, although other suitable light emitting devices may also be used. 196 LEDs can be incorporated to emit any color or color combination according to the desired emission effect. For example, in an embodiment according to the present invention, LEDs 196 can be adapted to emit red light. The bottom surface 194 of circuit board 144 is the side facing
Petition 870190080320, of 08/19/2019, p. 39/59 / 37 towards the bottom surface 138 of the second extrudate 134 (or alternatively the bottom surface 14 of the extrudate 10). If the extrudate 134 (or extrudate 10) is comprised of a clear or matte material, the light emitted from the bottom surface will appear substantially red. Alternatively, if other colors or color combinations are emitted from LEDs 196, the color emitted from a clear and matte top surface of extrusions 10 or 134 will be substantially the same as that emitted from LEDs 196.
[00102] However, in the case of the extrudate 120, since light is emitted through the bottom surface 138 of the second extrudate 134, it then passes into the chamber formed by the extrudate 120. The light will be dispersed through the extrudate 120 before it passes through the housing 122. Therefore, if LEDs 196 emit red light as in the example above, the light emitted through the housing 122 will appear substantially red if the housing 122 is comprised of a transparent or light red material. However, if the housing is comprised of a different color, the light emitted through the housing 122 may be a substantially different color from the light originally emitted from LEDs 196. For example, if the housing 122 is comprised of a transparent yellow material , the light emitted through the housing 122 may appear substantially orange. It is understood that any color or combination of colors can be transmitted from the extrudate 120 according to the color combination emitted from the LEDs 196 and the color of the housing 122.
[00103] The bottom surface 194 of circuit board 144 further comprises wires 192 to provide electricity to energize the light emitting devices. The wires 192 are incorporated into the bottom of the conductive supports 193, which run through the double-sided circuit board 144 to the top surface 186 of the circuit board 144. On the top surface 186, the supports 193 are adapted to accept the ends 151a151b wire 150 (shown in FIG. 18), with wire 150 attached to a power source
Petition 870190080320, of 08/19/2019, p. 40/59 / 37 external energy (not shown).
[00104] FIG. 25 represents a frame 200 using three interconnected extrusions 120, with the curved line 202 representing the pause between at least two of the extrusions 120, and the frame signal 204 that separates two of the extrusions. Extrusions 120, complete with integral light-emitting devices, are mounted and maintained in low profile against the side roof surfaces of the structure 200 such that extrusions 120 are substantially abutted on the surface, with any space between extrusions 120 and the surface of structure 200 provided by the length of the trunk 172 of the mounting brackets 170. The extrusions 120 are mounted and secured using the mounting brackets 170 described above. The extrusions 120 are positioned such that light emitted through the top surface 142 of the second extrudate 134 and the housing 122 will provide illumination out of the front of the mounted extrusions 120 as represented by the dashed portions 206. The light emitted as the backlight 208 and the light emitted through the housing 122 as represented by the hatch 208 can be two different colors. For example, structure 200 can be illuminated with yellow light, while the light emitted from the extrusions can be red. Any colors or combination of colors can be achieved.
[00105] While there are three extrusions 120 connected in this application, it is understood that any number of extrusions can be connected in various configurations. End caps 152 are provided at the ends of extrusions 120 to allow wire (s) 150 to pass through and / or between extrusions 120 and end caps 152. A power device (not shown) is connected to the wire (s) ) 150 to supply power to the connected extrudates 120. It is understood that end caps 152 with wire holes 164 can be provided where a wire in and out of an extrudate is desired. End caps 152 without wire holes 164 can be provided at the end of an extrudate 120 at the end of the

[00106] Although the present invention has been described in considerable detail with reference to certain preferred configurations thereof, other versions are possible. The housing / extrudate, mounting clip (s), and / or end cap (s) can be used on many different devices. The extrudate, mounting clip (s), and end cap (s) can also have many different shapes and can be interconnected together in many different ways, such as to form channel letters, extrusions to correspond to curved surfaces, and so on. onwards. Accordingly, the spirit and scope of the invention should not be limited to the preferred versions of the invention described above.
