Definitions
- the invention is based on an LED module according to the preamble of patent claim 1.
- LED modules with a protective film for protection against contamination are known. Furthermore, these LED modules can have passage openings for mounting the LED module to a mounting element by means of screws. If the film is not to be screwed during assembly, so the film must be removed before mounting, whereby the LED module, however, is no longer protected against dirt during assembly. Especially on construction sites, the risk of contamination is increased, such as by drilling or other construction site work resulting dust. Especially LED modules with silicon are konverguss very susceptible to dust and other Verun ⁇ Cleaners. In addition, in general, for example in an overhead mounting of an LED module by means of screw connection, the problem that is increased by the risk of falling out of the screws, the assembly cost of such an LED module.
- the object of the present invention is to provide an LED module that it is ⁇ enables and adequately protected against dirt easier assembly. This object is achieved by an LED module having the features of patent claim 1.
- the LED module according to the invention comprises at least one through-opening from a first side of the LED module to a mounting side opposite the first side of the LED module, wherein the through hole is so out ⁇ forms that a screw for fixing the LED module to a mounting element from the first page to the mounting side of the LED module is inserted into the passage opening.
- the LED module has a foil , which is at least partially adhesively arranged on the first side of the LED module.
- the film has at least a structure comprising at least one fürtren ⁇ drying of the film in the area of at least one passage opening of the LED module.
- the transection of the film in the region of the passage opening an insertion of a screw in the passage opening for mounting the LED module is made possible without having to remove the film during assembly.
- the LED module is advantageously protected during installation against contamination.
- the formation of the film with a structure in the form of at least one cutoff ensures that the screw is held in the passage opening even without screwing through the film alone, which considerably facilitates the assembly of the LED module according to the invention.
- a transection may in particular represent a slot-shaped interruption of the film, which in the normal state, ie, especially with mechanically tension-free, flat orientation of the film, no visible opening results.
- the structure is designed such that for removing a film penetrating, in the passage opening of the LED module at least partially introduced, not festge ⁇ screwed screw from the through hole a force is required, which is greater than that Weight of the inserted screw. It is thereby achieved that, for example, at an over-head assembly of the LED module a in the passage ⁇ port and through the at least one severing inserted screw, not by itself, especially by the influence of gravity, again falls out. So above all the overhead mounting can be very simplified, which also brings the positive effect of a reduced amount of time during installation with it.
- the diameter of the recess can furthermore be designed such that a diameter of a screw head of a screw inserted into the passage opening is smaller than the diameter of the recess and larger than the diameter of the passage opening, the recess provides a multiplicity of advantageous configurations, such as, for example that the film at Screwing the screw is not mitschraschraubt while covering the recess through the film.
- the film is arranged on the first side of the LED module such that it at least partially covers an opening of the recess when the screw is not inserted.
- This covering of the opening of the recess ensures that no dirt can get into the recess and into the passage opening of the LED module.
- the film is deformable, at least in the region of the depression, in such a way that a screw with a screw head can be inserted and screwed into the depression and into the passage opening in the depression.
- the LED module can be protected in the area of the recess by covering by the film, in particular before assembly, but at the same time, the film can be left on the LED module during assembly, since they are by their elastic or deformable properties does not interfere with the insertion of a screw.
- the LED module can also be protected from contamination during assembly, in particular in the region of the depression or in the region of the passage opening for the screw.
- the film is mitverschraubt to compensate for example, geometric irregularities or to dampen vibrations or even, with appropriate design of the film lie the screw in addition.
- the structure of the film may include a closed cutout in the form of a recess. Furthermore, the structure of the film may include a plurality of partitions, which are arranged crossing at a point. In addition, the structure of the film may comprise a recess and a plurality of cut-throughs, wherein the cut-throughs are arranged on a boundary line of the cutout. Furthermore, the structure of the film may have a plurality of partitions, which are formed as a perforation.
- the screw can be supported ⁇ th by clamping the screw neck by means of the structure of the film.
- the screw can be only partially inserted into the through hole, so that the screw head is still outside the depression.
- the foil can be arranged on the first side of the LED module such that it at least partially covers an opening of the depression in the case of a screw inserted into the passage opening.
- the falling out of the screw can be prevented by the at least partially covering the opening of the recess by the film.
- this may be accomplished that by appropriate deformable formation of the Fo lie the structure during insertion of the screw is deformed in the region of the recess and returns into its initial position after insertion of the screw, and in particular the opening of the recess at least in part ⁇ as covered again.
- the structure of the film can be formed such that the film is at least partially contacted by an inserted into the through-hole at its screw Schrau ⁇ benkopf.
- the film can be formed such that they are deformed so that a force out by the deformation of the laterally applied to the screw head sheet on the screw head will ⁇ exercise, and in particular by means of the film a Klem ⁇ upon insertion of a screw in the region of the depression mung of the screw head is effected so that the unscrewed screw is held in the through hole.
- the foil can have an adhesive layer in at least one area which is arranged non-contacting on the first side of the LED module. This can serve as a trap for contaminants, such as dust or lint, which are absorbed by the adhesive layer and be held. By this embodiment, the prevention of contamination of the LED module can be further optimized.

- FIG. 1 shows a schematic representation of an LED module 10 with a film 13 according to an embodiment of the invention.
- it can also be an LED module with one or more organic LEDs.
- the film 13 may be glued to a first side 11 of the LED module 10.
- the film 13 may also be provided with a sheet-like adhesive layer, which is also disposed in areas where it is not needed for attachment to the housing, but as a trap for contaminants, such as dust or lint, is used, which is absorbed and held by the adhesive layer become.
- This adhesive layer does not have to be continuous, but may also be applied partially or in a structured manner.
- ESD electrostatic discharge
- LED modules 10 to print on the film 13 with major Informa ⁇ functions such as handling instructions.
- handling instructions may be game, in ESD-sensitive LED modules have 10 out how to handle the modules, since it is not common for plumbers or electricians are trained in the handle lo ⁇ exercise of ESD sensitive components and for example at a construction site ESD compatible To ⁇ uite not or only very difficult to realize.
- An example of a further handling instruction would be the indication that the LED module may not be touched in the area of the LEDs or that pressure may be exerted on the LEDs.
- the film 13 can protrude beyond the first side 11 of the LED module 10, for example in the form of a pull tab 19.
- the pull tab 19 can be arranged in the region of a plug for the power supply of the LED module 10 and in particular cover this. So removing the protective film during the commissioning of the LED module 10 can not be forgotten, which could affect otherwise the Pro ⁇ going to press the LED module 10 as its life ⁇ life or light properties.
- the LED module 10 shown in FIG. 1 has, by way of example, two passage openings 15, which extend from the first side 11 of the LED module 10 to the opposite mounting side 12, to the LED module 10 with screws 16 inserted into it Through openings 15 can be inserted and screwed to be able to attach to a mounting element.
- the film 13 has a structure 14. This is adapted to hold a ⁇ into a through hole 15 inserted screw sixteenth
- the screws 16 provided can be mechanically held in place and special when over-head mounting do not fall out.
- the assembly can be greatly facilitated and on the other hand, such threading, holding or clamping the screws 16 through the structure 14 of the film 13 serve as preparation for assembly.
- a fitter does not have to remove the foil 13 before screwing on, which offers protection of the LED module 10 against contamination and contamination even during assembly.
- FIG. 2 shows a schematic representation of an LED module 10 with a film 13 and a screw 16 held by the structure 14 of the film 13 according to an embodiment of the invention.
- the structure 14 is designed so that a star structure of the cuts is used, which has a circle, in particular a circular recess, superimposed. Through the circular recess, the screw 16 in the Through hole are introduced and held by clamping the screw neck with the recess of the structure 14. Thus, the screw 16, even with overhead mounting, no longer fall out of the through hole 15, which greatly facilitates the assembly.
- Fig. 3 shows a schematic representation of a LED module 10 having a sheet 13, the structure 14 has a depression 18 partly covered, and a screw held within the Ver ⁇ indentation 18 by the structure 14 of the film 13 16 in accordance with an embodiment of the OF INVENTION ⁇ tion.
- the structure 14 is formed with star-shaped partitions of the film 13 and a central circular recess. Due to the deformation properties of the film 13, in particular in the region of the structure 14, or by elastic formation of the film 13, a screw 16 in the fürgangsöff ⁇ tion 15 of the LED module 10 are introduced, even if the circular recess is smaller in diameter as the screw head 17.
- the LED module 10 is configured such that it has a recess 18 in which the passage opening 15 is arranged.
- the diameter of the recess 18 is dimensioned so that the screw head 17 can be inserted into this recess 18. Due to the fact that the structure 14 of the film 13 at least partially covers this depression 18, the screw 16 can also be held in the passage opening 15 without being tightened.
- the screw 16 can be completely inserted by a fitter so that the structured region of the film 13 closes again after the insertion, thereby reliably preventing the screw 16 from falling out. Due to the deformable Formation of the film 13 and in that the structure 14 of the film 13 closes again, contamination of the LED module 10, even in the region of the recess 18 can be effectively prevented.
- Another advantage of the depression 18 is that when the screw 16 is screwed, there is no film 13 between the screw head 17 and the LED module 10, as a result of which the strength of the screw connection is permanently secured.
- FIG. 4 shows a schematic representation of an LED module 10 and a film 13 with a structure 14 which holds by deformation a screw 16 in a recess 18 of the LED module 10, according to an embodiment of the invention.
- the structure 14 is designed so that it does not close again when the screw 16 is completely inserted into the recess 18, but this is clamped by the structure 14 and held therewith.
- na ⁇ Moslich a combination of these training variants of the structure 14 also conceivable, so that for example a part of the star-shaped structure 14 is made longer than another part of the structure 14, so that the structure 14 closes partially over the screw 16 and teilwei ⁇ se the screw 16 holds by clamping.
- Fig. 5a shows an embodiment of the structure 14 as a star with only three beams.
- the cut-throughs of the film 13 are radially symmetrical about a boundary line of a ner circular recess arranged.
- the schematically drawn screw head 17 can be slightly larger than the circular punching.
- the circle punching is ideally just as large as the thread of the screw 16 in order, for example, to allow optimum clamping of the screw neck through the recess, as shown in FIG.
- a smaller or larger thread diameter may be very advantageous in embodiments according to FIGS. 3 and 4.
- the structure 14 may also be configured as a star with four beams, as shown in Fig. 5b, or even more.
- the structure 14 can also be designed as star-shaped partitions without circular punching in the middle, as shown schematically in FIG. 3 c.
- This embodiment is particularly suitable when the distance of the film 13 to the base of the recess 18 is sufficiently large, especially when the diameter of the recess 18 ⁇ is smaller than the depth of the recess 18, so that jamming of the film 13 zwi - See screw 16 and LED module 10 can be avoided ver ⁇ screwing.
- This variant embodiment is therefore particularly advantageous au ⁇ ßerdem because no punching drop occurs, which could remain in a non-reliable running punching the LED module 10th Thus it can be avoided that this waste can come to places where it is undesirable, such as between the base of the recess 18 of the LED module 10 and the screw head 17th
- FIG. 5 d shows an embodiment variant in which the structure 14 comprises a closed cut-through, in particular a circular punching. Preference may be this circular recess having a diameter which is equal to or larger than that of a ringenkop ⁇ fes 17.
- a screw 16 can hereby be held thereby, by punching voltage eccentrically to fürgangsöff- 15, in which the screw 16 is inserted, is introduced ⁇ is. If the screw 16 is inserted, it is likely to partially below the film 13 and is held until the Fixed To ⁇ supply, in particular up to screw, from the film. 13
- other shapes of the recess are possible, for example triangular, as shown in Fig. 5e, or also generally n-angular. Such shapes of the cutout are moreover also possible as center punching with severing of the film 13 at the boundary lines of the cutout, in analogy to FIGS. 5a and 5b.
- Fig. 5f shows a further embodiment possibility of the structure 14 of the film 13, again with a closed separation of the film 13 in the form of a recess.
- the star structure is not formed as a line structure, but as a star-shaped cutout.
- the structure 14 of the film 13 may also be formed by triangular-shaped film parts.
- 5g shows a particularly preferred embodiment of the structure 14 of the film 13.
- the structure 14 comprises several rectilinear cuts through the film 13, which intersect at a point, and moreover further severing of the film 13, the arc-like remplist ⁇ taltet are.
- the holding mechanisms illustrated in FIGS. 3 and 4 can be realized simultaneously.
- Another advantage is that even here no punching waste occurs, the could undesirably remain at a location of the LED module 10.
- the separation of the film 13 may also be formed as a perforation, as shown for example in Fig. 5h and Fig. 5i.
- Fig. 5h shows a structure 14 with a perforated predetermined breaking point and a single continuous punching.
- FIG. 5i shows a further embodiment variant of a structure 14 with a perforation.
- the perforation is executed on both sides and forms a kind of flap.
- the screw 16 can be held by clamping, as shown in FIGS. 2 and 4. be.
- the perforation can also be dispensed with, ie only a linear punching can be used in the middle. In this case, the screw 16 during insertion displace the film 13, whereby the screw 16 can be held simultaneously.
- the width ⁇ ren is also possible to carry out all of the structures shown and mentioned 14 with a through punching as a perforation or with combinations of perforations and continuous punching.
- such an LED module which has a film with a structure in the region of screw holes, wherein the structure is adapted to hold in the screw holes introduced screws, for example by clamping.
- the mounting of such an LED module in particular an over-head mounting, can be considerably facilitated because falling out of the screws can be prevented by the structure of the film, and on the other hand can be contaminated by this formation of the film LED module can be prevented much more effective, since it is possible to remove the film after the installation of the LED module, wherein the screw holes are covered by the film at least partially, and without the film mitverschraubt.
