Description

The present invention relates to a termination element for arrangement on a light-emitting diode strip according to the preamble of claim 1. The present invention further relates to a light-emitting diode strip according to claim 6, which is terminated with at least one of the aforementioned termination elements. In addition, the invention relates to a lighting strip with such a light-emitting diode strip according to claim 8.

The above-mentioned LED strip can be a flexible LED strip which is arranged in a lighting strip which is provided for lighting purposes in a building or on or in a vehicle, for example. Such a lighting strip is formed by mounting the LED strip in a provided flexible plastic profile, for example by gluing. This profile is also referred to as a base profile in the following text. The lighting strip formed from the above-mentioned parts is often cast with transparent plastic after the LED strip has been inserted into the receiving body in order to protect the LED strip located therein from To protect against environmental influences such as moisture, humidity and corrosion. This plastic is also referred to as potting compound in the following text.

Such a lighting strip with a light-emitting diode band and a method for its manufacture are described in the published international patent application WO 2018/069 453 A1 described.

A light-emitting diode strip, as mentioned above, is often made with a circuit board made of flexible plastic. This circuit board often has two or more copper tracks or copper layers extending along the length of the light-emitting diode strip, which are provided on a flexible circuit board. The light-emitting diodes are mounted on the circuit board using chip-on-board (COB) technology or SMD technology, for example, and connected to the copper tracks. These copper tracks must be electrically contacted at the ends of the light-emitting diode strip. To do this, a cable with a connector is often soldered to a copper track on the circuit board at the end remote from the connector. After the soldering process and the insertion of the light-emitting diode strip into the base profile, it can then be encapsulated with transparent plastic.

The patent specification discloses EN 10 2008 013 454 B4 a lighting strip in which a circuit board covered by a potting compound is positioned. At the end of the lighting strip there is a termination element which is drilled through to allow the electrical supply lines to pass through.

However, this does determine the length of the connecting cable for the lighting strip. However, one and the same type of lighting strip can be used in different places. To illuminate the interior of the body of a lorry or the interior of the trailer of a transport vehicle, it may be necessary to provide several examples of the same type of lighting strip with different cable lengths and/or different connectors at the cable ends. This presents the manufacturer of the lighting strip with the problem of having to provide a large number of lighting strips with different cable lengths and/or connectors for the connecting cable. If If the casting is done mechanically, cables and any connectors attached to them must also be transported through the casting machine. This is particularly problematic with long connecting cables.

For several reasons, it is therefore desirable that the electrical supply cables can only be connected after the casting. However, this requires reliable containment, i.e. mechanical separation of the liquid or gel-like casting compound during the application process. Reliable separation between the area to be cast and the area intended for electrical contact is necessary because the area of the LED strip intended for electrical connection must be kept free of casting compound.

The disclosure document EN 10 2009 020 851 A1 describes a sealing cover for protecting the electrical contacts of a molded lighting strip to enable the installation of an electrical connection to the lighting strip.

The patent specification US 10 753 596 B1 shows means for containing the potting compound in a lighting strip.

The disclosure document US 2017/0 198 889 A1 shows connector assemblies integrally formed at the end of a board of a light-emitting diode strip.

The closing element mentioned at the beginning is intended to provide both a reliable mechanical separation and sealing between the potting compound on the LED strip and the area of the LED strip to be electrically contacted, as well as to offer a flexible option for electrical contact.

The present invention is therefore based on the object of providing a termination element which meets the above requirements. A light-emitting diode strip intended for use with such termination elements is also to be provided. Finally, a lighting strip with such a light-emitting diode strip is to be provided.

To solve this problem, the invention has the features of claim 1 with regard to the closing element. Advantageous embodiments thereof are described in the further claims. With regard to the LED strip, the invention has the features of claim 6. With regard to the lighting strip, the invention has the features of claim 8.

The invention provides a termination element for arrangement on a light-emitting diode strip, wherein the termination element arranged on the light-emitting diode strip divides the light-emitting diode strip into a first region with light-emitting diodes arranged on the light-emitting diode strip and a second region for attaching electrical connecting means, wherein the light-emitting diode strip is designed to be received in an inner recess of a base profile with a bottom wall and lateral side walls extending from the bottom wall and the inner recess formed by the bottom wall and the side walls, in particular an elongated inner recess, wherein the termination element has a partition wall between the first region and the second region, wherein the partition wall has a first recess which is designed to receive the light-emitting diode strip along a section of a longitudinal extension of the light-emitting diode strip, wherein edges of the first recess seal the light-emitting diode strip against a potting compound when potting with potting compound of the first region of the light-emitting diode strip fixed in the base profile.

Such a light-emitting diode strip has a flexible circuit board that has a very large longitudinal dimension compared to its width. A plurality of light-emitting diodes are attached to one side of this circuit board, while the other side of the circuit board facing away from the light-emitting diodes can be arranged on the bottom wall of the base profile. The light-emitting diode strip is thus accommodated in the inner recess of the base profile. The first and second regions each extend in the longitudinal direction of the light-emitting diode strip. A light-emitting diode strip in the sense of the invention is only electrically contacted at one or both ends - viewed in the longitudinal direction.

A base profile can be designed as a flexible plastic profile and can accommodate the aforementioned LED strip on a bottom wall of the plastic profile. The plastic profile also has two side walls that extend from opposite sides of the bottom wall so far away from the bottom wall that the side walls protrude beyond a LED strip attached to the bottom wall. The bottom wall and the two side walls thus form an elongated, channel-shaped profile. After a LED strip has been attached to this profile, this channel-shaped profile is filled with a casting compound that is transparent at least in the area of the LEDs.

A closing element according to the invention serves to prevent the potting compound from overflowing at the ends of the LED strip into areas of the channel-shaped base profile for those areas of the base profile with the LED strip arranged therein that are not to be exposed to potting compound. Such closing elements are also referred to as wedges. Such a closing element can be attached to both ends - viewed in the longitudinal direction - of the LED strip before the LED strip is inserted into the base profile.

An end element according to the invention is designed with a partition to prevent the overflow of the casting compound. It is advantageous if this partition is designed such that it projects beyond the side walls of the base profile. A further feature of the partition is that it not only extends over a section running transversely to the longitudinal direction of the LED strip, but that two further sections of the partition also run parallel to two areas of the side walls of the base profile. This prevents the liquid casting compound from overflowing onto the outside of the side walls of the base profile when the flow of casting compound is stopped at the partition. These two sections of the partition running parallel to the side walls of the base profile are also designed such that they project beyond the side walls of the base profile.

It is advantageous if the outer cross-section of the end element is smaller than the inner recess of the base profile, with the exception of the three above-mentioned said sections of the partition wall projecting beyond the side walls of the base profile. This enables simple assembly of the finished lighting strip in a profile element. Such profile elements are used, for example, to enable interior lighting of the body of trucks. The end element according to the invention enables simple assembly of the finished lighting strip when the base profile is adapted to the profile element.

The above-described end element with the partition wall ensures a secure separation between two areas of a light-emitting diode strip arranged in a lighting strip, as described in the following text. Potting compound can be applied to the first area with the light-emitting diodes. On the other side of the partition wall is the second area intended for electrical contact, which is kept free of potting compound. This advantageously ensures that the finished lighting strip can be equipped with a cable of the desired length at any time after production. The connector can also be adapted to customer requirements at any time after the lighting strip has been manufactured. This reduces the variety of parts and simplifies storage. Another advantage is that the connection cable does not have to be transported through the potting machine and the device arranged at the end of the production line for the functional test of the lighting strip. Another advantage of this invention is the possibility of equipping the end element directly during or immediately after the respective circuit board has been fitted in a "pick and place" process together with the other electronic components such as LEDs and control circuits.

In one embodiment, the terminating element has a receiving space which is designed to enclose a third region of the light-emitting diode strip on all sides, wherein the third region is arranged between the first region and the second region.

A receiving space arranged between the first and the second area supports the effect of the partition by providing a volume into which a a certain amount of liquid casting compound can penetrate from the first area. This amount of liquid casting compound is prevented from reaching the second area, which is intended for electrical contact, by the additional provision of a receiving space. This means that it remains reliably possible to establish an electrical connection to the LED strip, for example by soldering.

The receiving space is designed so that its external cross-section is smaller than the cross-section of the inner recess of the base profile. This means that several LED strips can be arranged one behind the other in one section of the base profile. This enables continuous production of lighting strips if the base profile is only cut to length after it has been cast with casting compound. This means that it is no longer necessary to adjust the length of the base profile to the length of the LED strip to be manufactured according to the customer's requirements before casting. The base profile can therefore be provided in any length that is very long compared to the length of the LED strip.

It proves to be advantageous that the receiving space is connected to the partition wall on the side facing the second area. The partition wall can thus be used to mark the point intended for separating the base profile at one end of a lighting strip when several lighting strips are arranged one behind the other in a single base profile.

In a further embodiment, the closing element has a sealing lip on the edges of the first recess and/or on edges of a second recess at one end of the receiving space.

Such a sealing lip further increases the reliability of the separation between the first and second areas. The use of such a sealing lip requires either a low installation height of the means provided for the electrical contact on the circuit board, which can be solder pads, for example, or the attachment of the means provided for the electrical contact on the circuit board only after the end element has been attached to the circuit board.

In a further embodiment, the terminating element arranged on the LED strip has at least one receiving device for the LED strip which encompasses the LED strip from a side facing away from the LEDs to a side carrying the LEDs.

Such a receiving device, which can be designed as a groove, for example, serves on the one hand to further improve the effect of the partition with regard to the overflow of the casting compound from the first to the second area. On the other hand, this receiving device also enables reliable positioning of the end element on the LED strip.

In a further embodiment, a free space is arranged between a part of the end element arranged on the first region of the LED strip and an inner side of the side wall of the base profile.

If there is a free space between the base profile and the end element, it is possible to slide an element onto one end of a lighting strip, which presses the flexible base profile against the end element. Such an element can be provided, for example, as a protective device for the connection between the connecting cable and the LED strip to prevent it from kinking. By providing a free space, the reliability of such a protective device can be increased by improving the reliability of the connection between the base profile of the lighting strip and the protective device.

The invention further provides a light-emitting diode strip with a flexible circuit board, a plurality of light-emitting diodes arranged thereon and two opposite ends, to which at least one terminating element is attached to one of the ends.

In one embodiment, a termination element is attached to the LED strip at both ends.

If termination elements according to the invention are attached to both ends of the LED strip, both ends of the LED strip can be connected to cables be electrically connected. In this way, several LED strips can be linked together, i.e. connected electrically in series.

Finally, the invention provides a lighting strip with a light-emitting diode strip and at least one terminating element, wherein the light-emitting diode strip is arranged in a base profile and the base profile is filled with potting compound in a first region of the light-emitting diode strip up to a partition wall of the terminating element.

The LED strip is usually glued to the bottom wall of the base profile, for example with a double-sided adhesive tape or a liquid adhesive. The potting compound serves to protect the LED strip and the circuit board from environmental influences such as moisture and corrosion. Transparent plastic materials such as polyurethane are usually used, which are delivered in a liquid or gel state, for example in two components, and are hardened after potting, for example with electromagnetic radiation such as UV or IR light. The potting compound can also be made of silicone, acrylate or polyester, for example.

In one embodiment, the lighting strip has two terminating elements at the ends of the LED strip.

The invention is explained in more detail in the following text using the drawing. This shows:

• Fig.1 a perspective view of an embodiment of a closure element with the first region in the foreground;
• Fig.2 a perspective view of an embodiment of a closing element with the second region in the foreground;

• Fig.7 a cross-sectional view of an embodiment of a closure element.

Fig.1 The drawing shows a closing element 1 according to the present invention, wherein in the foreground the side can be seen on which the first area 16 of the LED strip 20 with the LEDs 21 is located after the LED strip 20 explained below has been attached. The closing element 1 has a partition wall 3 with the first recess 7. A section of the LED strip 20 can be introduced into this first recess 7 in the direction of the receiving space 9 by pushing the LED strip 20 in with one end, for example. In the foreground one can see the support surface 4 for the LED strip 20 and the groove-shaped receiving devices 5.

Fig.2 The drawing shows the same end element 1 as Fig.1 , whereby in the foreground the side can be seen on which the second area 17 of the LED strip 20 for electrical contacting is located after the LED strip 20 explained below has been attached. On the side of the partition wall 3 provided with the receiving space 9, the second recess 8, which is enclosed by the sealing lip 6, can be easily recognized.

The receiving space 9 can, for example, be a tubular elastomer element 10, the interior 19 of which has a volume above and below a light-emitting diode strip 20 mounted therein, that it can hold at least as much potting compound as usually flows in the direction of the second region 17 of the light-emitting diode strip 20 when the inflow at the Fig.5 shown casting compound 30 to the first area 16 of the LED strip 20 at the partition wall 3. For additional sealing of the second area 17 for electrical contact, a sealing lip 6 enclosing the second recess 8 can be formed on the tubular elastomer element 10 at this end of the receiving space 9.

This also in Fig.7 The sealing lip 6 shown is designed so that it is on the side of the closing element 1 facing the second area 17, which in Fig. 2 visible, sealingly encloses the LED strip 20. On the Fig.2 not shown, facing the interior 19 of the tubular elastomer element 10, the cross section of the second recess 8 of this sealing lip 6, designed to accommodate the LED strip 20, increases. In other words, this means that the cross section of the second recess 8 of the sealing lip 6 on the side shown in Fig.2 visible side is smallest. Here, the dimensions of the second recess 8 are designed just so that the LED strip 20 can be pushed through. The interior 18 of the tubular elastomer element 10 increases in size towards the inside of the receiving space 9. Such a sealing lip 6 can improve the sealing effect and thus the separation between the first area 16 and the second area 17.

Fig.3 The drawing shows an elastically formed base profile 11, which has a bottom wall 12 and two side walls 13. The channel-shaped inner recess 14 of the base profile 11 is formed between the bottom wall 12 and the side walls 13. The base profile 11 for receiving the LED strip 20 has two side walls 13 in the embodiment shown, which are formed in one piece with a bottom wall 12 of the base profile 11. The base profile 11 has in the longitudinal direction 15 according to the double arrow to Fig.3 its greatest extent. This double arrow 15 also indicates the longitudinal extent of the lighting strip 31, which has such a base profile and is explained below, and of a light-emitting diode band 20 fixed therein. The base profile 11 can be in the area of the outer sides the side walls 13 have a plurality of longitudinal ribs (not shown) which increase the rigidity of the base profile 11. These ribs also serve to hold and position the lighting strip 31 in a receiving profile (not shown in detail). Such a receiving profile can be made of aluminum, for example. These receiving profiles are mounted flush with the inner wall or the ceiling plate of the body of a truck, for example, in order to enable the interior lighting of the body with lighting strips according to the invention mounted in the receiving profiles.

The base profile 11 can be an elastic profile with a trough-shaped or channel-shaped cross-section, which is made, for example, from a thermoplastic elastomer (TPE), in particular a urethane-based thermoplastic elastomer (TPU), or also from a polyvinyl chloride (PVC) material or also from an elastic thermosetting material.

In Fig.4 The drawing shows how the LED strip 20 with the LEDs 21 attached to it is fixed to the bottom wall 12 of the base profile 11, for example by means of a double-sided adhesive tape (not shown). The end element 1 is arranged at the end of the base profile 11. The circuit board 24 of the LED strip 20 passes through the end element 1. For this purpose, the LED strip 20 was pushed through the partition wall 3 and the receiving space 9 so that the soldering pads 22 on the circuit board 24 are freely accessible. The LEDs 21 can be mounted on the circuit board 24 using chip-on-board (COB) technology. This makes it possible to provide the light-emitting diodes 21 at such a small distance from one another that the light-emitting diodes 21 produce a uniform light for the observer, i.e. the observer does not perceive individual points of light, but rather a continuous, one-piece or single-piece lighting strip 31 with a homogeneous radiation of the light.

On the side of the LED strip 20 carrying the LEDs 21, predetermined markings can be provided which serve as positioning aids for the Users represent positions at which the user can position the terminating element 1 on the LED strip 20 in order to obtain a defined projection of the second region 17 of the LED strip 20 relative to the terminating element 1.

Based on Fig.5 The drawing also shows that the inner recess 14 of the base profile 11 is filled with a hatched potting compound 30 which completely covers the LEDs 21 on the LED strip 20. The potting compound 30 can be made of a polyurethane material, for example, and can be transparent, translucent, or even multi-layered. For example, a partial layer directly enclosing the LEDs 21 can be transparent and an area or partial layer arranged above it can be translucent, for example, so that the light emission of the LEDs 21 is not impeded and the optical appearance on the top of the potting compound 30 appears uniform. Furthermore, the sheath 26 with three lines 27 of the connecting cable 28, surrounded by a border, for example in the form of a shrink tube 25, can be easily recognized. The three lines 27 of the connecting cable 28 are soldered to three solder pads 22 on the circuit board 24. To complete the assembly, the shrink tube 25 must be pushed over the three exposed connecting cables 27, the exposed part of the circuit board 24, the end element 1 and a part of the base profile 11 and heated.

While the above text describes connecting the LED strip 20 to the connecting cable 28 by means of a soldering process, it is also possible to connect the connecting cable 28 to the LED strip 20 by means of insulation displacement terminals, spring clips or splicing. As already mentioned, however, during production, means for connecting the LED strip 20 to the connecting cable 28 are only to be attached to the LED strip after a terminating element 1 has been attached if they have a greater height than the relatively flat soldering pads 22. This changed production sequence makes it possible to push the LED strip 20 through the recesses 7 or 8 in the terminating element 1 in the event that the recesses 7 or 8 cannot be enlarged by, for example, folding open a two-part terminating element 1 about an axis parallel to the longitudinal direction 15.

Fig.6 shows a top view of a lighting strip 31 which is provided with a connecting cable 28. In addition, in this embodiment of the invention, a protective device 32 can be seen which is pushed onto the outside of the base profile 11. This protective device 32 can be made of a plastic which is stiffer than the materials of the base profile 11 of the LED strip 20 and the connecting cable 28. Such a protective device 32 can in particular prevent the cable 28 from kinking at the soldering points 22. It is easy to see that pushing on the protective device 32 reduces the free space 33 between the base profile 11 and the end element 1.

The version with protective device 32 represents an alternative to the one described in connection with Fig.5 shown embodiment of the protection of the connection between the circuit board 24 of the LED strip 20 and the connecting cable 28. Another possibility for protecting the connection between the circuit board 24 of the LED strip 20 and the connecting cable 28 is an overmolding, which can be done for example with a hot melt substance.

Fig.7 shows a cross-section of a closing element 1. The LED strip 20 with the flexible circuit board 24 is arranged in the closing element 1. The first recess 7 in the partition wall 3 and the second recess 8 at the end of the receiving space 9 are easily recognizable. Sealing lips 6 extend from both recesses to the LED strip 20. The receiving space 9 consists of a tubular elastomer element 10 and the interior 19. The closing element 1 divides the LED strip 20 into the first area 16 and the second area 17. The receiving space 9 encloses the third area 18 of the LED strip 20.

With the features mentioned above, lighting strips with lengths of a few decimetres can be produced. But lighting strips with a length of 15 metres, for example, can also be produced without any problem. With LEDs connected in parallel, the achievable length of the lighting strip is only determined by the specific resistance and the cross-section the electrical conductors which serve to supply the individual light-emitting diodes on or in the circuit board 24 of the light-emitting diode strip 20.

With regard to features of the invention not explained in detail above, express reference is made to the patent claims and the drawings.
