Definitions

  • the present invention relates generally to a composite panel and to a lighting element, where the lighting element, in use, is received by the composite panel.
  • the present invention also relates to an arrangement comprising a composite panel and at least one lighting element.
  • Light arrangements consisting of a two electrically conductive layers with an insulating layer or core in-between, often formed as a sandwich board, sheet, panel, or the like, are generally known where one or more lighting elements are inserted into the panel in such a way that an electrical circuit involving the two electrically conductive layers and the lighting element is closed.
  • the insulating layer or core is usually relative low density, to keep the overall weight down, and the electrically conductive layers may be made from a relatively lightweight electrically conductive material such as aluminium.
  • Lighting elements used in this context are often light emitting diodes (LEDs).
  • Such panels may be used for general lighting or for signs where the lighting elements may form a logo, text, graphics, etc.
  • a panel it is not unusual for a panel to comprise e.g. about 20 - about 400 light elements although it of course can be more and also fewer.
  • light elements may even dislodge themselves completely from the panel. Such light elements may easier go missing and/or be damaged during transportation and/or handling.
  • a composite panel for receiving a lighting element, the lighting element comprising a housing comprising a first and a second electrical contact element, the composite panel comprising a first and at least a second electrically conductive layer, and at least one electrically insulating layer, where the at least one electrically insulating layer separates and electrically isolates the first and the second conductive layers from each other, wherein the composite panel comprises a receiving recess adapted, during use, to receive the lighting element in at least the electrically insulating layer so that the first electrical contact element of the lighting element forms an electrical connection with the first conductive layer and the second electrical contact element of the lighting element forms an electrical connection with the second conductive layer, and the receiving recess comprises at least one first securing element adapted to engage with at least one second securing element of the lighting element thereby securing the lighting element in the composite panel when the lighting element is received by the receiving recess.
  • a composite panel is provided that readily enables that one or more lighting elements inserted into the composite panel is securely held in its respective receiving recess, even during transport and/or handling of the composite panel where the panel may bend or warp to some extent, since the first securing element together with the second securing element will restrict movement of an inserted lighting element in a direction out of the composite panel.
  • the at least one first securing element is a further recess located in at least a part of the electrically insulating layer.
  • the at least one second securing element is a resilient member fitting into the further recess.
  • the further recess is located substantially all the way about a central axis of the receiving recess.
  • the further recess located in at least a part of the second conductive layer and comprises a first rim or edge in the second conductive layer adapted to engage a distal end of the second securing element when the lighting element is received by the receiving recess and wherein the second securing element is made of an electrically conductive material and it is also the second electrical contact element.
  • electrical power to an inserted lighting element may be transferred via the second securing element abutting against the second conductive layer in the further recess when the second securing element is made as an electrical contact or conductor and is appropriately connected to in the lighting element.
  • this facilitates a double function of the second securing element simplifying the construction of the composite panel and lighting element.
  • a lighting element may be inserted into the receiving recess without requiring any specific rotational oritentation, which is a great advantage during assembly/insertion.
  • the further recess comprises a second rim or edge, wherein the second rim or edge is rounded.
  • the second rim or edge is rounded enables a simpler drilling or milling process of the further recess since it is easier to have a gradual/rounded transition than a sharper one. Additionally, easier installation of a lighting element is also facilitated since it then cannot get stuck on the second rim or edge so easily or at all during installation of the lighting element into the receiving recess.
  • the receiving recess is substantially cylindrical and defines a substantially circular opening in the second conductive layer, a substantially cylindrical volume in at least a part of the electrically insulating layer, and also goes at least partly into the first conductive layer.
  • the composite panel further comprises a transparent cover fixed to the second electrically conductive layer, wherein the transparent cover is made from a material selected from polycarbonate, plexiglass, glass, etc.
  • the transparent cover may e.g. be glued to the second electrically conductive layer or fixed to it in another way.
  • the transparent cover may e.g. have a concave or convex part to spread or focus the emitted light.
  • the transparent cover may e.g. also comprise an O-ring or other seal to ensure that the lighting element is water and/or gas-tight, which may be important for certain off-shore and/or marine uses.
  • a lighting element for being received by a receiving recess of a composite panel
  • the composite panel comprises an electrically insulating layer electrically isolating a first and a second conductive layer
  • the lighting element comprises a housing comprising a first and a second electrical contact element, and a light source
  • the lighting element is adapted to form an electrical connection between the first electrical contact element and the first conductive layer of the composite panel and an electrical connection between the second electrical contact element and the second conductive layer of the composite panel when the lighting element is received by the receiving recess, and comprises at least one second securing element adapted to engage with at least one first securing element in the receiving recess thereby securing the lighting element in the composite panel when the lighting element is received by the receiving recess.
  • the at least one first securing element is a further recess located in at least a part of the electrically insulating layer.
  • the at least one second securing element is a resilient member fitting into the further recess.
  • the further recess located in at least a part of the second conductive layer and the second securing element comprises a distal end adapted to engage a first rim or edge in the second conductive layer of the further recess when the lighting element is received by the receiving recess and wherein the second securing element is made of an electrically conductive material and it is also the second electrical contact element.
  • the receiving recess is substantially cylindrical and defines a substantially circular opening in the second conductive layer, a substantially cylindrical volume in at least a part of the electrically insulating layer (106), and also goes at least partly into the first conductive layer.
  • the lighting element comprises at least one light emitting diode.
  • a lighting arrangement comprising a composite panel and embodiments thereof as described above and throughout the description and at least one lighting element and embodiments thereof as described above and throughout the description.
  • Figure 1 a schematically illustrates a cross section of one embodiment of a composite panel.
  • a lighting element not shown; see e.g. 200 in Figures 2, 3 , 4, and 5
  • a first not shown; see e.g. 203 in Figures 2 , 4, and 5
  • a second not shown; see e.g. 204 in Figures 2 - 5
  • the composite panel 101 comprises a first 105 and a second 105' electrically conductive layer. Furthermore, the composite panel 101 also comprises an electrically insulating layer 106, where the electrically insulating layer 106 separates and electrically isolates the first and the second conductive layers 105, 105' from each other.
  • the composite panel 101 has in this way a 'sandwich' structure with a core being the electrically insulating layer 106 separating the first and second conductive layers 105, 105'.
  • the electrically insulating layer 106 is of a generally non-conducting material and may be of a relative low density (e.g. as compared to metal) material to keep the overall weight of the composite panel 101 down.
  • the electrically insulating layer 106 may be made of certain types of materials e.g. polyethylene (PE), rubber-like polymers, most plastics, etc.
  • the width of the electrically insulating layer 106 may depend on a specific use.
  • the electrically conductive layers 105, 105' may in principal be made from any conductive material e.g. like a suitable sheet metal.
  • the electrically conductive layers 105, 105' are preferably made of a relatively lightweight electrically conductive material, e.g. aluminium.
  • the electrically conductive layers 105, 105' may be made of stainless steel, copper, etc.
  • the width of each electrically conductive layer may be different depending on specific use, but will typically be somewhat smaller than the width of the electrically insulating layer 106.
  • the widths of the two electrically conductive layers may be the same or may be different from each other, again depending on specific use.
  • the composite panel 101 further comprises at least one receiving recess 115 where each receiving recess 115 is adapted to receive a lighting element during use in at least the electrically insulating layer 106 so that a first electrical contact element (not shown; see e.g. 203 in Figures 2 , 4, and 5 ) of the lighting element forms an electrical connection with the first conductive layer 105 and the second electrical contact element (not shown, see e.g. 204 in Figures 2 - 5 ) of the lighting element forms an electrical connection with the second conductive layer 105'.
  • a given light source such as e.g. one or more LEDs, is electrically connected to the first and second electrical contact elements so that a circuit is formed.
  • the second securing element and the second electrical contact element of the lighting element are the one and same element, which will provide some further advantages, as will be explained in the following.
  • the actual design of the lighting element including design and location of the its first and second electrical contact elements may vary as long as it enables separate connection with the first and second conductive layers 105, 105'.
  • the receiving recess 115 goes in certain embodiments, e.g. as shown in Figure 1a , all the way through the second electrically conductive layer 105' and in this particular and similar embodiments also all the way through the electrically insulating layer 106 while only partially into the first electrically conductive layer 105 thereby exposing the first electrically conductive layer 105 for electric connection while also using it as an abutment surface.
  • the receiving recess 115 may in certain embodiments, e.g. as shown in Figure 1a , be substantially cylindrical about a central axis 112 whereby the receiving recess 115 then defines a substantially circular opening in the second conductive layer 105' and a substantially cylindrical volume in at least a part of the electrically insulating layer 106 for receiving a lighting element.
  • the receiving recess 115 may alternatively go fully through also the first conductive layer 105, at least at some locations, just as long as the first electrical contact element is designed accordingly.
  • Such receiving recesses 115 may generally be made in the composite panel 101 relatively easy and efficiently during manufacture e.g. using appropriate drilling or milling processes.
  • the receiving recess 115 furthermore comprises at least one first securing element 102 adapted to engage with at least one second securing element (not shown; see e.g. 202 in Figures 2, 3 , 4, and 5 ) of the lighting element thereby securing the lighting element in the composite panel 101 when the lighting element is received by the receiving recess 115.
  • the one or more lighting elements inserted into a composite panel is securely held in its respective receiving recess, even during transport and/or handling of the composite panel where the panel may bend or warp to some extent.
  • the first securing element 102 may together with the second securing element restrict movement of an inserted lighting element in a direction out of the composite panel 101. It is even further advantageous if the first and/or second securing elements still facilities easy insertion of the lighting element, especially since some composite panels may comprise a high number of inserted lighting elements, and also if the first and the second securing elements engage in an expedient and simple way.
  • the at least one first securing element is a further recess 102 located in at least a part of the electrically insulating layer 106.
  • Shown in Figure 1 a is an embodiment comprising one further recess 102 going all the way around, i.e. being 360 degrees, inside the receiving recess 115. This facilitates simple insertion of the lighting element into the receiving recess 115.
  • the further recess 102 forms an upper rim, edge, etc. (see 109 in Figure 1 b) for keeping an inserted lighting element in place after insertion.
  • the further recess 102 are additionally also located in the second conductive layer 105'.
  • That the further recess 102 is located (also) in the second conductive layer 105' enables that electrical power to the lighting element may be transferred via the second securing element abutting against the second conductive layer 105' in the further recess 102 when the second securing element is made as an electrical contact or conductor and is appropriately connected to in the lighting element.
  • the further recess 102 need not necessarily go all the way around on the inside of the receiving recess 115. It could e.g. go only a substantial part around, e.g. 350 degrees or less, and still provide more or less the same functionality.
  • the further recess 102 could also be separated into two or more further recesses instead of a single continuous recess. The smaller the recess is about the central axis 112 and the greater the number of smaller separate recesses the single recess is replaced by to more careful the lighting element has to be inserted in relation to its specific rotational orientation (to ensure that the contacts add up), but it may still provide some of the other mentioned advantages.
  • the at least one second securing element is a resilient member (not shown; see e.g. 202 in Figures 2, 3 , 4, and 5 ) fitting into the further recess 102.
  • the resilient member may e.g. be a resilient leg, peg, or similar. And as mentioned, it may be made of an electrically conductive material and be appropriately connected enabiling also to double in function as the second 204 electrical contact.
  • the second securing element(s) is/are a resilient member secured at one end to the housing of the lighting element while the other end is free and the secured end is the first end of the two to be inserted then it may simply be pressed against the housing of the lighting element during insertion and then snap into the further recess at a proper location thereby locking and securing the lighting element in the composite panel 101.
  • the further recess 102 may also be manufactured using an appropriate drilling or milling process, e.g. using a CNC (computer numeric control) milling machine e.g. a high speed machine capable of up to about 40.000 rpm.
  • the receiving recess 115 and the further recess 102 may be produced in a single milling run or process e.g. using a single tool making it relatively easy to manufacture.
  • the receiving recess 115 and the further recess(es) 102 may be produced by two different milling runs or processes e.g. with two different tools.
  • the composite panel 101 will comprise a plurality of receiving recesses and thereby a plurality of lighting elements in use but may of course in principle also comprise only one receiving recess and one lighting element if that is suitable for a given use.
  • the lighting element When inserted into the receiving recess 115, the lighting element will, in certain embodiments, be flush or in line with the the second conductive layer 105', i.e. the lighting element will not extend beyond the second conductive layer 105'. In other embodiments, the lighting element may extend beyond and in such cases, the lighting element may comprise a collar, sleeve, skirt, or the like.
  • Figure 1b shows an expanded view of a portion 110 of the composite panel of Figure 1 a.
  • the further recess 102 comprises a first rim or edge 109 in the second conductive layer 105' and in a part of the insulating layer 106 being adjacent to the second conductive layer.
  • the first rim or edge 109 is adapted to engage the second securing element, e.g. more specifically adapted to engage a distal end (not shown; see e.g. 202' in Figure 5 ) of the second securing element, e.g. in the form of a resilient member, leg, peg, etc., when the lighting element is received by the receiving recess 115.
  • the second securing element in the form of a resilient member, leg, peg, etc. will snap into the further recess 102 thereby locking and securing the lighting element in the composite panel from being moved out again. Even if the composite panel is bend or warped during handling or transportation.
  • the angle between the rim or edge 109 and the insulating layer is substantially rectangular or 'sharp', i.e. about 90 degrees. The angle may be different to some extent. What is significant is that the angle enables reliable securing of an inserted lighting device and if the angle differs too much from 90 degrees (either direction) then the second securing element may more easily 'pop' out thereby releasing an inserted lighting device.
  • the further recess 102 also comprises a second rim, edge, or the like 108.
  • This second rim or edge 108 is preferably more rounded than the sharper first rim or edge 109. That the second rim or edge 108 is rounded enables a simpler drilling or milling process of the further recess 102 since it is easier to have a gradual/rounded transition than a sharper one. Additionally, that it is rounded also facilitates easier installation of the lighting element 200 since it then cannot get stuck on the second rim or edge 108 so easily or at all during installation of the lighting element 200 into the receiving recess 115.
  • first rim or edge 109 is in the second conductive layer 105' as well enables using the second securing element also as the second 204 electrical contact element (see 202 and 204 in Figures 2 - 5 ).
  • the receiving recess 115 ends partly into the first electrically conductive layer 105, which creates a further rim or edge 111 between the first electrically conductive layer 105 and the electrically insulating layer 106.
  • This further rim or edge 111 may also be substantially rounded in order to enable a simpler drilling or milling process of the receiving recess 115.
  • Figure 1c schematically illustrates a view of a part of a composite panel, e.g. the one shown in Figure 1a , in an insertion direction of the lighting element.
  • the view corresponds to seeing Figure 1 a from 'above'.
  • the receiving recess 115 reveals a part of a first conductive layer 105 otherwise located under the second conductive layer 105' with an electrically insulating layer (not shown; see e.g. 106 in Figures 1 a and 1 b) between them as already explained.
  • a further recess 102 adapted to receive one or more corresponding second securing element(s)/resilient member(s) (not shown; see e.g. 202 in Figures 2, 3 , 4, and 5 ) e.g. arranged in pairs (see e.g. 211 in Figures 3 and 4 ) when the lighting element is received by the receiving recess 115, where the second securing element(s)/resilient member(s) may also function as second 204 electrical contact element(s).
  • This and corresponding embodiments enables very reliable securing of an inserted lighting element. It also enables that an inserted lighting element do not need to have a specific rotational orientation in the receiving recess 115 when being inserted.
  • Figure 2 schematically illustrates an exemplary embodiment of a lighting element to be used with the composite panel of Figures 1 a - 1 c, and 6 shown from one side.
  • a lighting element 200 comprising a housing 201 comprising at least a first 203 and a second 204 electrical contact element, a light source (not shown; see e.g. 301 in Figure 3 ), and at least one second securing element 202.
  • the light source may e.g. comprise one or more LEDs, and be electrically connected to the first and second electrical contact elements 203, 204.
  • the lighting element 200 is for being received by a receiving recess of a composite panel (not shown; see e.g. 115 and 101 in Figures 1a - 1c , and 6 ) like the ones shown and explained elsewhere.
  • the lighting element 200 will form an electrical connection between the first electrical contact element 203 and a first conductive layer (see e.g. 105 in Figures 1 a - 1 c, and 6) of the composite panel and an electrical connection between the second electrical contact element 204 and a second conductive layer (see e.g. 105' in Figures 1 a - 1 c, and 6) of the composite panel when the lighting element 200 is received by the receiving recess 115 of the composite panel.
