Description

Technical Field

[0001] The invention is intended to improve a profile assembly for constructing exhibition stands or shop equipment. Summary of the invention

[0002] According to the invention, for this purpose a profile assembly is provided with the features of claim 1. Advantageous developments of the invention are mentioned in the dependent claims.

[0003] A profile assembly for building exhibition stands or shop equipment has a supporting profile, wherein the supporting profile has at least one cavity that is continuous in the longitudinal direction of the supporting profile and at least two legs that are continuous in the longitudinal direction. The profile assembly also has a covering profile, wherein the covering profile is made of a light-transmissive material at least in sections, in particular completely made of translucent plastic. The supporting profile has a latching device at the free end of its legs, which can cooperate with a matching latching device on the covering profile. An LED lighting device is arranged on the inner side of the supporting profile, so that during operation, the LED lighting device radiates light in the direction of the inner side of the covering profile.

[0004] Therefore, the profile assembly comprises a supporting profile and a covering profile. The supporting profile is made of extruded aluminum, for example, and is suitable for forming a supporting component of a booth or store equipment. In the connected state of the supporting profile and the covering profile, the inner side of the supporting profile is opposite to the inner side of the covering profile, and the supporting profile and the covering profile form a closed cross section. By arranging an LED luminous device (the luminous device is covered with a partially transparent covering profile) on the inner side of the supporting profile, it is feasible to arrange lighting in the profile assembly itself. Thus, a booth or store equipment can be created, in which vertical pillars and / or horizontal frames are illuminated from the inside, and thus light is radiated to the outside. Exactly in a dark space, a completely new visual impression can be created. For example, the supporting structure of the booth can be illuminated from the inside. A completely new possibility is also obtained for the illumination of the booth or store equipment itself. For example, the profile assembly has a square or rectangular cross section, and can, for example, radiate light outward at two sides adjacent to each other and arranged perpendicularly to each other. However, it is also feasible to provide lighting strips only on one or more sides of the profile assembly. It is even possible to form a support or frame with a profile assembly according to the invention which has a square or rectangular cross section and radiates light on all four sides. Of course, it is also possible to provide a profile assembly with a circular or oval cross section which either emits light outwards essentially over its entire circumference or only over a portion of its circumference. The support profile has at least one cavity which is continuous in the longitudinal direction of the support profile. A so-called turnbuckle is pushed into the cavity at the end side, which then locks in the cavity at the end side and has, for example, two locking hooks that protrude beyond the end side of the support profile. With the locking hooks, the support profile can then be anchored in the undercut groove of another support profile by bracing the locking hook against the undercut from the inside. Such a connection with a turnbuckle and an undercut groove is known in exhibition building profiles. However, the cavity can also be used, for example, to arrange elements of a threaded connection, such as nuts and bolts or the like. By appropriately coordinating the light transmittance or scattering effect of the cover profile and the radiation angle and number of the LED lighting devices, a coherent and substantially uniform illumination of the cover profile from the inside can be provided over the entire surface of the cover profile. This creates the impression that the cover profile itself is luminous, since no discrete light source can be seen through the cover profile. Advantageously, the LED lighting devices are arranged on the inner side of the support profile over the entire length of the support profile, so that the profile assembly radiates light over its entire length.

[0005] In a development of the invention, the profiled cover element has exactly two legs, wherein the outer sides of the legs of the profiled cover element are arranged perpendicular to one another at least in the region of their free ends.

[0006] The cover profile can thus cover an angle of 90° and, for example, complement the support profile to form a rectangular or square profile component. The profile component can thus radiate light at an angle of 90°. The two legs of the cover profile can butt against each other perpendicularly at their connection point, but they can also be connected to each other by means of a rounded section.

[0007] In a development of the invention, the supporting profile has exactly two legs, wherein the outer sides of the at least two legs are arranged at right angles to each other, and wherein the covering profile is provided with locking means at the free ends of the legs of the covering profile, which can cooperate with the locking means at the free ends of the legs of the supporting profile.

[0008] As a result, the cover profile and the support profile form an elongated profile assembly with a rectangular or square cross section. However, a rhombus-shaped cross section is also feasible, for example. By snapping the cover profile into the snap-in means at the support profile by means of its snap-in means, the cover profile can be fixed to the support profile in a very simple manner, in particular without tools. Advantageously, the snap-in means at the cover profile is designed as a projection that is continuous in the longitudinal direction of the cover profile, while the snap-in means at the support profile is designed as a continuous undercut groove in the longitudinal direction of the support profile. In this way, the cover profile can be fixed firmly and here without tools at the support profile and can also be released again from the support profile in a non-destructive manner.

[0009] In a development of the invention, the two legs of the supporting profile are arranged at an angle of 90° to one another and the legs of the covering profile are arranged at an angle of 90° to one another.

[0010] In this way, in the connected state of the supporting profile and the covering profile, the profile assembly has a rectangular or square cross section.

[0011] In a development of the invention, the LED luminous means has at least a first strip and a second strip with LEDs arranged one behind the other in a longitudinal direction, wherein the light emission directions of the two strips are oriented substantially perpendicular to one another.

[0012] In this way, light can be emitted in two mutually perpendicular directions, for example in the direction of a first leg of the cover profile and in the direction of a second leg of the cover profile, wherein the two legs are arranged at an angle of 90° to one another. In this way, a very uniform illumination of the cover profile can be achieved. The center line of the emission cone or the emission angle is considered to be the light emission direction. In the case of a plurality of LEDs arranged aligned with one another, which form an LED strip, the center lines of the emission cones of successively arranged LEDs are also aligned. This determines the light emission direction of the LED strip. Essentially perpendicular here means an angle between 85° and 95°, in particular 90°.

[0013] In a development of the invention, a third strip is provided with LEDs arranged one behind the other in the longitudinal direction, wherein the light emission direction of the third strip is arranged at an angle of approximately 45 degrees, in particular between 40 and 50 degrees, to the light emission direction of the first strip and to the light emission direction of the second strip.

[0014] In this way, an angular range of 90° or even slightly more than 90° can be illuminated uniformly. For example, the light emission direction of a first LED strip is oriented perpendicularly to the first leg of the cover profile, the light emission direction of a second strip is oriented perpendicularly to the second leg of the cover profile, and the light emission direction of a third strip is directed toward the connection between the first leg and the second leg of the cover profile. In this way, a very uniform illumination of the cover profile can be achieved and, in particular when using translucent cover profiles, the impression can be obtained that the cover profile radiates light over its entire surface, since the individual light sources cannot be seen from the outside of the profile assembly.

[0015] In a development of the invention, a plurality of strips with LEDs arranged one behind the other in the longitudinal direction are arranged on a common flexible substrate.

[0016] In this way, not only the distance between the individual LEDs in the longitudinal direction but also the distance between the individual LEDs in the transverse direction can be precisely maintained, which significantly facilitates the assembly of the profile assembly according to the invention. By configuring the substrate to be flexible, the individual LED strips can be arranged at different angles to one another without having to worry about the distance between the individual LEDs in the transverse direction changing over the length of the LED strip. Advantageously, the substrate is designed in this case such that a modular structure is provided and the substrate can be cut off at predetermined intervals, for example 4 cm, without impairing the electrical connection and thus the operating properties of the LEDs on the uncut parts.

[0017] In a development of the invention, the support profile has fastening surfaces for the LEDs, wherein the fastening surfaces are at least partially arranged at an angle to one another.

[0018] In a development of the invention, the support profile has a fastening surface for the LED, which is arranged on a curved surface which is continuous in the longitudinal direction of the support profile.

[0019] In a development of the invention, the legs of the supporting profile each taper toward the free end.

[0020] In this way, very little shading can be achieved by the free ends of the legs of the support profile in the area of ​​the connection to the cover profile. Advantageously, the inner side of the leg is designed in such a way that the reflection of light incident on the inner side of the leg takes place in the direction of the inner side of the cover profile.

[0021] In a development of the invention, the legs of the supporting profile extend on the inner side in an angled manner toward the free end.

[0022] Advantageously, the legs of the support profile are curved convexly toward the inner side of the covering profile on the inner side, which inner side faces the inner side of the covering profile. This allows reflection of light incident on the legs of the support profile toward the covering profile.

[0023] In a development of the invention, the legs of the support profile are mirror-finished (sometimes referred to as having a reflective coating), polished or white on the inside.

[0024] In this way, very good reflection can be achieved. If diffuse reflection is desired, a slightly rough but still reflective surface can also be provided, for example, on the inner side.

[0025] In a development of the invention, the cover profile is formed in one piece from translucent polycarbonate.

[0026] Translucent polycarbonate is light-permeable to a certain extent, but nothing can be discerned through it. Therefore, a cover profile made of polycarbonate that is illuminated from the inside does not allow the individual discrete LEDs causing the illumination to be discerned, but rather evokes the impression of homogeneous self-illumination over its entire surface. In addition, polycarbonate can be easily manufactured, for example by extrusion or pultrusion, and has sufficient strength on the one hand and is sufficiently elastic and impact-resistant on the other hand to be connected to a supporting profile without any problems, for example by means of a snap-on device.

[0027] In a development of the invention, a groove is provided at each free end of the legs of the supporting profile, wherein the free ends of the legs of the covering profile can be snapped into the respective groove.

[0028] Advantageously, the groove at the free end of the leg of the supporting profile is undercut so that the covering profile can be securely snapped in. For this purpose, the free end of the leg of the covering profile advantageously has a strip-shaped protrusion that is continuous in the longitudinal direction of the covering profile and that is coordinated with the undercut groove of the supporting profile.

[0029] In a development of the invention, the continuous cavity of the supporting profile has an octagonal cross section.

[0030] The cavity with an octagonal cross section allows the insertion of the turnbuckle at least in two mutually perpendicular orientations, if possible even in two mutually perpendicular positions and two positions each inclined by 45° thereto.

[0031] In a development of the invention, the outer sides of the legs of the supporting profile are each provided with at least one undercut recess.

[0032] Such an undercut groove serves to connect a further profile component perpendicularly to the first profile component, wherein a screw thread engages in the undercut groove and securely connects the end face of the vertical profile component to the first profile component.

[0033] In a further development of the invention, a voltage supply device and / or a control unit for the LED luminous means is inserted into the cavity of the support profile.

[0034] In this way, the voltage supply device and / or the control unit can be placed in the profile assembly itself, so that, for example, only thin cables need to be led out of the profile assembly. Of course, it is also feasible to arrange the energy storage in the profile assembly. However, such an embodiment is usually only suitable for short-term operation of the LED light-emitting device.

[0035] In a further development of the invention, the voltage supply device and / or the control unit are arranged in a milled-out portion in the support profile. For example, the side of the cavity which is continuous in the longitudinal direction in the support profile is milled. The voltage supply device and / or the control unit can then be arranged and fastened in the support profile in a very simple manner by means of such a milled-out portion. In order to replace the control unit and / or the voltage supply device, the profile assembly does not have to be approached from its end side. In this way, the voltage supply device and / or the control unit can be replaced even in the installed state of the profile assembly. It is thus possible to replace the control unit and / or the voltage supply device by simply removing the cover profile.

[0036] In a development of the invention, the profile arrangement has vertical struts and horizontal frames, wherein both the struts and the frames are each formed by means of a supporting profile and a covering profile.

[0037] In this way, for example, the entire supporting structure of a trade fair stand or shop equipment can be designed to be self-luminous. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 A support profile 10 for a profile assembly according to the invention is shown in front view. The support profile 10 has a first leg 12 and a second leg 14, wherein the two legs 12, 14 (which are Figure 1 On the outside of each leg, a groove 16 or 18 with undercuts on both sides is arranged approximately in the middle. Figure 1 The cross section visible in FIG continues in the longitudinal direction of the support profile. The support profile 10 is provided with a cavity 20 which is approximately octagonal in cross section and continues in the longitudinal direction of the hollow profile and in which a turnbuckle 22 is arranged. Figure 1 As can be seen from the figure, the turnbuckle 22 can not only Figure 1 The turnbuckle 22 has a locking hook 24 which protrudes beyond the end side of the turnbuckle. Figure 1 In the recess 18, the hook 24 of another turnbuckle can be seen, which is inserted into the other supporting profile 100. The hook 24 can be retracted with the help of an eccentric assembly. In order to fix the supporting profile 100 vertically to the supporting profile 10, the turnbuckle is inserted into the cavity of the supporting profile 100 and pushed towards the outside of the leg 14 of the supporting profile 10 until the hook 24 acts on the undercut in the recess 18 from behind. The eccentric of the turnbuckle is now manipulated and moved into the dead center. The hook 24 now holds the supporting profile 100 firmly to the supporting profile 10. The possibility of such fixing of supporting profiles to each other by means of turnbuckles 22 is known.

[0049] The support profile 10 has a further cavity which is continuous in the longitudinal direction and which is provided either for static reasons or, as will be explained further on, for pushing in or inserting a voltage supply and a control unit.

[0050] The support profile 10 has a central element 26 on its inner side, in which a cavity 20 is arranged which is octagonal in cross section. At the transition from the central element 26 to the leg 12 and at the transition from the central element 26 to the leg 14, a recess 28 or 30 undercut on one side is provided. Turnbuckles or other functional components can also be fixed in these undercut recesses 28, 30, but cables can also be inserted into these recesses, for example. The central element 26 connects the inner sides of the legs 12, 14 and thus ensures that the support profile 10 can mechanically withstand high loads, so that large exhibition stands, usually supporting structures, can also be built.

[0051] An undercut groove 32 is provided at the free end of the leg 12 and an undercut groove 34 is provided at the free end of the leg 14, wherein the grooves 32, 34 are designed to be continuous and identical to one another in the longitudinal direction of the support profile 10. The undercut of the grooves 32, 34 is designed to be weaker and have a rounded course. The grooves 32, 34 are provided for snapping into a cover profile, see Figure 2 .

[0052] The inner sides of the legs 12, 34 are each designed to taper in their end regions 36 and 38. The taper is achieved by the inner sides of the legs extending in a convex curvature toward the ends. The curvature here points away from the outer sides of the legs 12, 14. As explained further, this not only achieves a taper of the legs, but also a reflection of the light incident on the curvature regions 36, 38 in the direction of the cover profile, see Figure 2 .

[0053] Figure 2 A profile assembly 40 is shown, having been Figure 1 The support profile 10 explained and the cover profile 50 placed on the support profile 10. The cover profile 50 has two legs 50 arranged perpendicular to each other and each of which is flat on the outside. Figure 2 In the state presented in FIG. 4 (in which the supporting profile 10 and the covering profile 50 are connected to each other), the profile assembly 40 thus has a square, generally rectangular cross section. Figure 2 It can be seen that the free ends of the legs of the cover profile 50 rest on the free ends of the legs 12, 14 of the support profile 10. The cover profile 50 is made of translucent plastic, in particular translucent polycarbonate, and is illuminated from the inside. Figure 2 In the example shown in FIG. 4 , when viewed from above and from the right, the entire upper side and the entire right side of the profile component 40 thus appear to be self-luminous.

[0054] In order to illuminate the cover profile 50 from the inside, LED lighting means in the form of three LED strips 52, 54, 56 are arranged on the inside of the support profile 10, wherein the three LED strips are arranged on a common flexible (biegbar, sometimes referred to as bendable) substrate 58. Each of the LED strips 52, 54, 56 has a plurality of LEDs 60 arranged in series, wherein the LED strips 52, 54, 56 are arranged on the inside of the support profile 10. Figure 2 In the illustration, only one LED 60 is visible in each case in the region of the LED strips 52 , 54 , 56 .

[0055] A light emission direction 62, 64 or 66 is drawn with a dashed line on each of the LEDs 60. It can be seen that the light emission direction 62 of the first LED strip 52 is oriented perpendicularly to the light emission direction 66 of the second LED strip 56. The light emission direction 62 of the first LED strip 60 is oriented perpendicularly to the leg of the cover profile 50. Therefore, the light emission direction 62 strikes the inner side of the first leg of the cover profile 50 perpendicularly, which is located at the bottom of the cover profile 50. Figure 2 The middle is located in the upper part.

[0056] The light emission direction 66 of the second LED strip 56 is oriented perpendicularly to the second leg of the cover profile 50 . Figure 2The second LED strip 56 is arranged on the right. Therefore, the light emission direction 66 of the second LED strip 56 is perpendicular to the inner side of the second leg of the cover profile 50. The emission angle is also indicated by a dashed line at the LED 60. The light emission directions 62, 64, 66 each form an angle bisector of the emission angle.

[0057] The light emission direction 64 of the third LED strip 54 is arranged at a 45° angle to the light emission direction 62 of the first LED strip 52 and at a 45° angle to the emission direction 66 of the second LED strip 56. Therefore, the light emission direction 64 of the third LED strip 54 is at a 45° angle to the first leg and the second leg of the cover profile 50.

[0058] exist Figure 2 As can be seen in FIG. 1 , the third LED strip is arranged to illuminate the corner area of ​​the cover profile 50, and the first LED strip 52 is arranged to illuminate the corner area of ​​the cover profile. Figure 2 The upper leg is provided in the middle, and the third LED strip 56 is provided to illuminate the cover profile 50. Figure 2 The middle leg is located on the right.

[0059] exist Figure 2 It can also be seen in FIG. 1 that the bending section 36 at the free end of the first leg 12 of the supporting profile 10 only covers the cover profile 50. Figure 2 In the same way, the curved section 38 at the free end of the second leg 14 of the supporting profile 10 only covers the small area of ​​the covering profile 50 at the free end of the upper leg. Figure 2 The small edge area of ​​the right-hand leg.

[0060] In order to fix the three LED strips 52, 54, 56, a flexible substrate 58 is placed and fixed, for example glued, on a curved or at least angled surface on the inner side of the support profile 10. As a result, the LED strips 52, 54, 56 are automatically oriented in the described manner. The curved fixing surface for the substrate 58 or the fixing surface for the substrate 58 with a plurality of sections arranged at an angle to each other simultaneously forms part of the outer side of the octagonal cavity 20 of the support profile 10.

[0061] Figure 3 Shows Figure 2 Exploded view of a profile assembly 40. The support profile 10 is provided with two legs 12, 14. The cover profile 50 is only shown in short sections. As indicated by the arrows, the cover profile 50 is placed onto the support profile 10 and then latched onto the support profile, as in Figure 2 As can be seen in FIG. 3 , the three LED strips 52 , 54 , 56 are arranged on a common substrate 58 and are fastened to the inner side of the support profile 10 .

[0062] An electric energy supply device 70 is provided for operating the LED lighting device. A control unit 72 is provided for controlling the LED lighting device. A connecting cable 74 is provided for supplying the energy supply device 70 with electric energy. Of course, the connecting cable 74 is connected to the energy supply device 70 during operation, which is not shown for simplicity. For example, the connecting cable can be connected to the power supply network or also to a battery. In the same way, the LED light strips 52, 54, 56 are of course connected to the control unit 72 and the energy supply device 70 via conductive paths on the common substrate 58 and cables that are not shown.

[0063] In order to be able to arrange the energy supply device 70 and the control unit 72 in the support profile 10, a rectangular milling section 76 is provided on the inner side of the support profile 10. With the milling section 76, the two cavities of the support profile 10 are open over a certain length, see also Figure 5 As indicated by the arrows, the energy supply device 70 and the control unit 72 can thus be inserted into these cavities of the support profile 10. The connecting cables 74 are led out at one or both end sides of the support profile 10. U-shaped clamps 78 are inserted into the respective end sides of the support profile 10 and serve as cable protection if the connecting cables 74 have to be laid at an angle, for example, in order to be guided into the next profile component.

[0064] In order to keep the energy supply device 70 and the control unit 72 in the cavity of the support profile 10, a closing profile 80 is provided. The closing profile 80 is coordinated with the milled portion 76 in length and width. Sliding locks 82 are provided at both ends of the closing profile 80, with which the closing profile 80 can be held on the support profile 10 in a preset position. Thus, the energy supply device 70 and the control unit 72 can also be firmly held in the support profile 10 by the closing profile 80. For example, the control unit 72 is used to control the luminous intensity of the LED lighting device or the color of the LED lighting device 60. The control unit 72 can be controlled from outside the profile assembly 40, for example, by means of a wireless remote control.

[0065] The control unit 72 can be designed in a suitable manner in order to also automatically implement a change in the luminous intensity or a change in the color of the LED luminous means, for example.

[0066] Figure 4 The diagram shows the Figure 3 The area at the end of the lower left arrangement passes through Figure 3 4. A cross-sectional view of a supporting profile 10 and a covering profile 50 of a profile assembly 40. In this area, a milling section is provided in the supporting profile 10 in order to pass a connecting cable 74 (see Figure 3 ) is led out from the cavity of the supporting profile 10.

[0067] Figure 5 A further section through the profile assembly 40 is shown in the region in which the closing profile 80 is placed onto the milled-out 76. The closing profile 80 is anchored to the support profile 10 by means of a sliding catch 82 and thereby holds the energy supply unit 70 and the control unit 72 (not shown) in the support profile 10. The hollow space of the support profile is accessible from the side via the milled-out 76.

[0068] exist Figure 4 and Figure 5 In FIG. 5 , the latching projections at the free ends of the two legs of the cover profile 50 can also be clearly seen, which latching projections engage in undercut grooves at the free ends of the legs of the support profile 10 .

[0069] also, Figure 4 and Figure 5 Also visible in FIG. 5 is a flexible substrate 58 with three LED strips 52 , 54 , 56 .

[0070] Figure 6 The figure shows three support profiles 10A, 10B and 10C, each of which is provided with an LED lighting device. Figure 6 In the illustrated figure, only the supporting profiles 10A, 10B are provided with the covering profiles 50A, 50B, respectively. Of course, the covering profiles not shown can also be clipped onto the Figure 6 On the supporting profile 10B in.

[0071] The supporting profile 10B is arranged vertically and forms a section of a support column. The two supporting profiles 10A, 10C are arranged horizontally and form a part of a horizontal frame.

[0072] In each of the support profiles 10A, 10C, a turnbuckle 22 can be seen which projects beyond the end face of the respective support profile 10A, 10C and serves to connect the support profile 10A, 10C to the support profile 10B. To this end, the hook of the turnbuckle 22 of the support profile 10A is introduced into the undercut groove 16 on the outer side of the support profile 10B and latches there, while the hook of the turnbuckle 22 of the support profile 10C is introduced into the undercut groove 18 on the outer side of the other leg of the support profile 10B and latches there. The eccentric of the turnbuckle 22 is actuated here from the outer side of the support profiles 10A, 10C, which is respectively directed backwards, through the opening in the support profile.

[0073] therefore, Figure 6 The profile assembly can achieve uniform illumination of the two outer sides of the cover profile 50a, the two outer sides of the cover profile 50c and the two outer sides of the cover profile not presented and placed on the support profile 10B. Thus, a spatial angle consisting of a vertical support and two horizontal frames is generated, which radiates light.

[0074] exist Figure 6 It can also be seen in the illustration of how the connecting cables 74 are led out of the supporting profiles 10A, 10B, 10C.

[0075] Figure 7 The figures show various embodiments of the profile assembly according to the invention. Figure 7 a shows a support profile 102 which, except for the non-existent undercut recesses 28, 30 (cf. Figure 1 ) is implemented identically to the supporting profile 10, and the supporting profile 102 is provided with a covering profile 104, whose two legs arranged perpendicular to each other are connected by means of a rounded area 106.

[0076] Figure 7 b shows Figure 2 Profile component 40.

[0077] Figure 7 c shows a support profile 108 which is designed slightly differently than the support profile 10 .

[0078] Figure 7 d shows a support profile 110 which, in contrast to the support profile 108 , is not provided with an undercut recess on its outer side.

[0079] Figure 7 e shows a support profile 112 , the inner structure of which is designed slightly differently than in the case of the support profiles 108 , 110 , and which therefore however has a curved or angled fastening surface for a flexible substrate of an LED luminous means.

[0080] Figure 7 Figure 1 shows a support profile 114 which is star-shaped and has a total of four legs which each extend at an angle of 90° between them. Two cover profiles 116 can be arranged at the free ends of the legs. All four cover profiles 116 are translucent and can thus create a profile assembly that is illuminated from the inside on four sides.

[0081] Figure 7 g shows a support profile 118 which is provided at the free ends of its legs with recesses which are rectangular in cross section and therefore have no undercuts. The cover profile 120 is inserted into these recesses with the free ends of its legs.

[0082] Figure 7 h shows a support profile 122, to which a covering profile 124 is snapped. However, the covering profile 124 does not extend beyond the free ends of the legs of the support profile 122.

[0083] Figure 8 Another support profile 126 is shown. This support profile 126 has three closed outer sides, in which undercut grooves are arranged. Figure 8 In the upper region of the support profile 126, a U-shaped cross section is formed with two legs 128, 130. The two legs 128, 130 are respectively provided with a strip-shaped protrusion at their free ends, which has a rounded outer contour and extends inwardly toward the opposite leg 128 or 130. The base of the U-shaped cross section is flat and is used to arrange a plurality of LED lighting devices.

[0084] Fig. 9 The profile assembly according to the invention is shown with a support profile 126 and a cover profile 132 made of translucent polycarbonate placed on the support profile 126. The cover profile 132 is essentially plate-shaped, but has rounded recesses at its two longitudinal edges that are open to the respective sides and are coordinated with the projections at the free ends of the legs 128, 130. As a result, the cover profile 132 can be locked to the support profile 126 in a very simple manner by Fig. 9 It is pressed from above onto the free ends of the two legs 128 , 130 until the inwardly projecting projections on the legs 128 , 130 engage in respective grooves on the longitudinal edges of the cover profile 132 .

[0085] On the basis of the U-shaped cross section of the support profile 126, a total of three LED strips 134, 136, 138 can be seen, each with a plurality of LEDs arranged one after the other and aligned with one another, which are arranged on a common basis. With the aid of the LED strips 134, 136, 138, the inside of the cover profile 132 can be illuminated uniformly, so that the outside of the cover profile 132 is also illuminated uniformly, without the individual LEDs of the LED strips 134, 136, 138 being visible from the outside of the cover profile 132. The curved insides of the legs 128, 130 serve here to reflect light onto the inside of the cover profile 132 and thus ensure uniform illumination and prevent the formation of shadows.

[0086] Furthermore, the support profile 126 is also designed as a recess with cavities and undercuts, which have been Figure 1 The support profile 10 is explained.
