Description

The invention relates to a light rail system for the reversible mounting of LED lighting.

State of the art

LED lamps are electrical light sources that use light-emitting diodes to generate light. LEDs are energy-saving lamps. The service life of LEDs can be up to 50,000 hours. LED lamps require less electrical power to produce the same brightness. They achieve a higher level of effectiveness and have higher energy efficiency. LEDs are usually more economical than most other lamps.

LED strips or flexible LED modules usually have built-in resistors for operation with direct voltages of 12 or 24 V. They can be operated with voltage-stabilized power supplies or batteries. The strips can often be divided at marked points so that whole sections, consisting of three LEDs and resistors, for example, are retained when shortened. Due to the linear light generation in a very small space, they offer many design options.

The DE 20 2017 005 166 U1 discloses "A modular nose equipped with LED lamps for hanging in rail systems". A light slide is disclosed which has a universal holder for rail systems, whereby both the holder clips and the holder components to be attached for curtain rails or drapery rails can be screwed on.

The disadvantage of the well-known LEDs is that they are difficult to install and remove from existing profiles, such as aluminum profiles, as they are often glued or screwed into the profile to be held there. The installation and replacement of LED lamps is then only possible with great effort. If there are large temperature fluctuations in the area of application, this often leads to a reduction in adhesive strength. This often leads to the glued LED lighting coming loose over time.

LED spotlights built into aluminum profiles are therefore usually offered as complete sets. In this case, it is necessary to cut a hole according to the required installation diameter. However, the aluminum construction is weakened by the point lighting. In addition, the use of LED spotlights, which represent a point light source, makes homogeneous illumination impossible.

The object of the invention is therefore to provide an installation option for LEDs which enables an easy-to-install, reversible installation of LEDs in a profile and a good light image with uniform and homogeneous illumination.

Disclosure of the invention

The invention is disclosed by the features of the main claim. Embodiments and developments are the subject of the further claims following the main claim.

A light rail system is disclosed that is easy to install and is also suitable for use in outdoor areas. The light rail system is also designed to be water and moisture-proof and insensitive to temperature fluctuations.

A light rail system is disclosed which can be reversibly mounted, in particular for subsequent installation, and which creates a light image without individual light points. For this purpose, the light rail system has an assembly unit. A light strip in the form of an LED strip within an LED body usually has light points. The light point representation is reduced the more LEDs are installed in the same space. So-called COB strips (chip on board) can also be used. These strips, which are almost free of light points, are inserted into a plastic casing, in particular a silicone casing. The distance between the LED strip and the light exit surface causes the light cones to completely overlap, whereby the light point representation disappears completely. The casing is designed as a light body approximately 12 mm wide and approximately 8 mm high. The light emitted by the LEDs emerges in the direction of a translucent light surface on the top of the casing. Silicone, for example, is used, which can be relatively easily inserted into suitable structures due to its deformability and holds in place due to its own clamping force. The water-resistant properties and the higher resistance to mechanical stress also lead to a longer service life. Yellowing due to UV radiation is reduced. The LED strip is inserted into the casing. The casing can be pre-produced. The LED strip is then cast in with a silicone nozzle. This makes the LED strip more temperature-resistant and provides additional protection against mechanical influences. This casing is then inserted into a mounting profile, in particular an aluminum profile. The The cover is inserted by clipping it into the aluminum profile. This can be done by creating grooves or elongated tabs in the side parts of the plastic cover for fixing, which can be inserted into the aluminum profile by gently pressing them together due to their soft design and can be clipped into a tab on the aluminum profile by releasing them, for example. These grooves or tabs serve as assembly units. This means that the LED strip is held in place without the need for gluing.

The mounting profile for the light rail can also be designed as a short mounting profile, which is used to fix the LED body in a specific spot. This can be used to compensate for small deviations in the alignment line. The short mounting profile is also useful if you want a non-rectilinear light image. Circles, curves, lettering or logos can also be designed.

An additional silicone shoe can also be used as a mounting adapter. This serves as a mounting unit and can be arranged directly around the cover and clipped into the groove of the cover. This mounting adapter from the silicone shoe is made of silicone in particular and serves as a widening option in order to adapt the LED lighting, which is fixed in width due to production, to existing mounting profiles that have a mounting opening that is slightly larger in width. The silicone version is helpful for easier insertion of the cover with the LED strip into the aluminum profile, as the dimensions of the cover and any different designs of the aluminum profiles can be compensated for by the silicone shoe.

In another embodiment, a different type of installation is used to insert the light strip into the mounting profile. Here, the mounting unit is designed as a mounting rail and has the option of accommodating magnets. This type of installation achieves different installation results. On the one hand, the use of the mounting rail enables the alignment and alignment of the light rail system when several mounting profiles are required in the longitudinal direction. On the other hand, the magnetic design enables the lighting to be fixed reversibly, quickly and in an easy-to-install manner, even on magnetically non-conductive surfaces such as aluminum.

For this purpose, the mounting rail has a length of approx. 5 cm to 20 cm and a width of 8 - 10 mm, for example. It has several options for holding magnets, for example neodymium magnets. The mounting rail has at least two drill holes and can be fixed to a non-conductive surface using countersunk screws, for example. If the surface is magnetically conductive, fixing with screws is not necessary.

Depending on the total length requirement of the lighting, several mounting rails can be arranged in the longitudinal direction. For this purpose, at least two to three mounting rails are provided per meter of lighting. The mounting rails are attached in such a way that those located on an abutting edge of two mounting profiles overlap them in order to achieve a straight alignment of the mounting profiles.

The mounting profile is clipped onto the mounting rail. The mounting profile has a certain amount of play to enable alignment and to ensure that several mounting profiles are aligned straight one behind the other. The mounting profile is made from aluminum, which is not magnetically conductive. For this reason, a magnetically conductive metal strip is integrated. The mounting profile is designed so that it can accommodate the light strip. The mounting is carried out by a mounting profile that is precisely manufactured to fit the light strip or the LED body, which forms the light rail system, in particular by clipping or clamping. In the LED body or the LED strip, neodymium magnets, for example, are arranged approximately every 5 - 10 cm. The LED strip can then be inserted into the larger mounting profile. It is held in place by the effect of the magnets. This is an advantage over the state of the art for significantly easier transport and storage, as the light strip can be rolled up.

Another example of installation is the use of point magnets with an integrated hole cutout or a drill hole for screwing onto a non-magnetic surface.

The light rail system according to the invention has the advantage that subsequent lighting can be added to existing patio roofs, particularly outdoors, without weakening the statics.

The light rail system can also be used for living room lighting or for a front door canopy. A lighting groove can be formed in the front door canopy into which the light rail system can be inserted.

In 1 is an LED body 10 for a light rail system 100, cf. 3 , shown. The LED body 10 is designed as a plastic casing, in particular a silicone casing 12. The LED body 10 is designed, for example, as a strip of approximately 12 mm width and approximately 8 mm height. Front caps 13 are attached to the respective ends of the LED body 10. The light emitted by LEDs 20, cf. 2 , within the LED body 10 emerges in the direction of a translucent luminous surface 14. Silicone is used because it is mechanically resilient, flexible, water-resistant and also more robust against weather influences and does not yellow as quickly. The casing 12 can be pre-produced. The casing 12 has grooves 16 on its respective side surfaces or also elongated lugs in the side parts of the plastic casing for fixing. These grooves 16 or lugs serve as assembly units 200 in one form of fixing units. A connecting cable 17 is also formed.

2 shows a cross-section of the LED body 10 with square grooves 16 with cast-in LED strip 18, in which no light points are visible and thus a continuous light effect is achieved.

3 shows a cross-section of the LED body 10 with a mounting profile 22. The LED body 10 is received with an integrated groove 16 in the mounting profile 22, which is designed in particular as an aluminum profile, and is fixed by a nose 24 integrated in the mounting profile 22. The grooves 16 or noses 24 thus serve as mounting units 200. The LED body 10 is thus held without an adhesive process. The light rail system 100 is thus designed to be reversible for subsequent installation, since the clipped-in cover 12 can be removed from the mounting profile 22 by gently pushing it in and pulling it out.

4 shows that an additional silicone shoe can also be used as an additional mounting unit 200. This serves as an additional mounting unit 200 and is designed as a silicone shoe or mounting adapter 26. The mounting adapter 26 is arranged directly around the casing 12 and clipped into the groove 16 of the casing 12. The mounting adapter 200 serves to increase the application area and is available in different thicknesses, with the aim of adapting the LED body 10 of a given size to different sizes of mounting profiles 22. For example, a 12 mm LED body 10 can be accommodated in a 15 mm mounting profile 22 with a 3 mm mounting adapter. In this embodiment, the mounting adapter 26 is designed in a "short" version. It has a projection 28 that engages in the groove 16 of the casing 12. The mounting adapter 26 has no further extension upwards in the direction of the luminous surface 14.

5 the mounting adapter 26 is designed as a “long” variant. It is provided with a continuation of its side legs above the projection 28 in the direction of the luminous surface 14.

6 shows how a mounting adapter 26 is arranged within a receiving profile 22. The mounting adapter 26 serves to facilitate the insertion of the LED body 10 with the LED strip 18 into the receiving profile 22, since the dimensions of the LED body 10 and any different designs of the receiving profiles 22 can be compensated for by the silicone shoe, i.e. the mounting adapter 26. The LED body 10 is inserted into the receiving profile 22 together with the mounting adapter 26. This allows any play between the external dimensions of the LED body 10 and the receiving profile 22 to be compensated for.

7 shows a further embodiment of an assembly unit 200. In this embodiment, the assembly unit 200 is designed as a mounting rail and has a magnet 32 embedded in a casting compound 30. This magnet 32 is arranged in a lower part of the receiving profile 22. This lower part of the receiving profile 22 is separated from an upper part of the receiving profile 22 by a separating base 34. A magnetically conductive metal rail 36 is arranged on the separating base 34. The LED casing 12 is arranged on the metal rail 36 mentioned. A further magnet 32' is arranged inside the casing 12. The LED strip 18 with the individual LEDs 20 is arranged on this magnet 32'. The magnet 32' as well as the LED strip 18 and the LEDs 20 are cast with the silicone casting compound 30. The LED strip 18 is held to the mounting profile 22 by the action of the two magnets 32, 32' without gluing.

8 represents the mounting unit 200 in the form of a mounting rail with magnets 32 in a casting compound 30 of the mounting unit 200. Screw holes 37 are formed.

9 shows the arrangement 8 from above. Screws 40 are used for connection.

10 shows a light rail system 100 mounted on terrace rafters 38 with mounting units 200 in the embodiment with magnets.

11 represents an LED body 10 with the luminous surface 14 and two grooves 16. The LED body 10 is arranged on a short receiving profile 23 and held there.

12 represents the short receiving profile 23, in the side parts of which lugs 24 are formed, which are inserted into grooves 16 of 11 snap into place.

13 shows the LED body 10 inserted in the short profile 23. The lugs 24 are locked in place.

14 shows a magnet 32 in a design as a square point magnet. The magnet 32 has a borehole 42 for inserting a screw 40 into the borehole 42 for screwing onto a non-magnetic substrate.

15 shows a magnet 32 in a design as a round point magnet. The magnet 32 also has a borehole 42 for inserting the screw 40 into the borehole 42 for screwing onto a non-magnetic substrate.

16 shows the point-by-point assembly with a magnet 32 designed as a point magnet and a counter magnet 32' integrated in the LED body 10. The inserted screw 40 is shown in dashed lines within the magnet 32.

17 represents the point-by-point mounting with the magnet 32 designed as a point magnet with the screw 40 and a counter magnet 32' integrated in the LED body 10 as well as a magnetically conductive metal rail 36.

All features presented in the description, the following claims and the drawings can be essential to the invention both individually and in any combination with one another.
