Element.
    In Fig. 1, a first embodiment of an application according to the fastener 1 is sketched in perspective. The fastening element 1 is designed for a connection between an LED board and a luminaire component. In Fig. 1, a corresponding LED board 2 is partially indicated by dashed lines.
    The fastener 1 is configured to be attached to the LED board 2. Fig. 1 shows a state in which the fastening element 1 is fixed as intended on the LED board 2. Fig. 2 shows a corresponding cross-sectional sketch. In the example shown, the LED board 2 has a through opening 21 into which the fastening element 1 is inserted when it is fastened to the LED board 2.
    Furthermore, the fastening element 1 has means for connecting the fastened to the LED board 2 fastener 1 with the lamp component. In FIG. 2, an end region of a pin-like holding element 10 of a corresponding luminaire component 3 is shown by way of example.
    In the first embodiment shown here, the fastening element 1 for attachment to the LED board 2, two resilient arms 4, 5 for a latching connection between the fastener 1 and the LED board 2, and two, extending in a plane E Preferably, the design is such that the two abutment areas 6, 7 bear against a first surface area 21 of the LED board 2 and the two resilient arms 4, 5 against a second, the first surface region 21 opposite second surface portion 22 of the LED board 2 press when the fastener 1 is fixed as intended on the LED board 2. Preferably, the design is such that for fixing the fastener 1 to the LED board 2, the locking connection is sufficient, that is, by the locking connection alone the attachment can be realized.
    Furthermore, in the first exemplary embodiment shown here, the fastening element 1 comprises a base region 8 with a passage opening 9 for the passage of the peg-like holding element 10 of the luminaire component 3. For a particularly easy connection, the base region 8 points inwards with respect to the passage opening 9 Spring tongues 11 on. For example, a clamping connection can be provided between the spring tongues 11 and the pin-like holding element 10. For example, the spring tongues 11 may be designed such that they can cut into the pin-like holding element 10 with their inwardly directed edges, so that a quasi-permanent clamping connection can be achieved. Alternatively, however, the design can also be, for example, such that a detachable clamping connection between the fastening element 1 and the peg-like retaining element 10 is effected.
    The base element 8 can - as shown here - be formed extending in the plane E, wherein extending the two resilient arms 4, 5, starting from the base region 8 on a first side S1 of the plane E.
    The spring tongues 11 are preferably, as outlined in Fig. 2, for example, designed such that they extend with respect to the plane E obliquely to the first side S1. Thus, a particularly secure connection to the peg-like holding element 10 can be effected. In this way, the fastening element 1 is suitable for the peg-like holding element 10 being inserted through the through-opening 9 coming from a second side S2 of the plane E lying opposite the first side S1, as indicated in FIG. 2 by an arrow.
    Alternatively, it may be provided that the spring tongues 11 designed such that they extend with respect to the plane E obliquely to the second side S2. In this way, the fastening element 1 is suitable for the peg-like holding element 10 coming from the first side S1 of the plane E being inserted through the passage opening 9.
    The resilient arms 4, 5 are in particular designed such that they can deflect each other to elastic. Thus, the fastener 1 is particularly easy to connect to the LED board 2, quasi by snapping.
    Preferably, the resilient arms 4, 5 holding portions 41, 51, which are formed with respect to the passage opening 9 facing outward. Thus, suitable contact areas of the fastening element 1 are formed, which press in the fastened state against the second surface area 22 of the LED board 2.
    As can be seen, for example, from FIG. 1, the two abutment regions 6, 7 preferably directly adjoin the base region 8. In particular, it may be provided that the base region 8 extends in the plane E, like the abutment regions 6, 7; manufacturing technology advantageous and space-saving can be provided that the base portion 8 is designed plan and also the contact areas 6, 7 are each designed plan, as sketched in Fig. 1.
    The fastening element 1 can advantageously be formed from one piece manufacturing technology advantageous. It can be made bent for example from a stamped sheet metal part.
    In Fig. 3 is a plan outlined on the fastener 1. As shown, here the lead-through opening 9 is formed centrally with respect to the base region 8. The design is preferably such that the two resilient arms 4, 5 lie on a first straight line G1 and the two contact areas 6, 7 on a second straight line G2. Further preferably, the design is also such that the projection of the first straight line G1 on the plane E and the projection of the second straight line G2 on the plane E include an angle α which is greater than 30 ° and less than 150 °, preferably greater than 45 ° and smaller than 135 °, so for example, as shown in Fig. 3 outlines 90 °. Thus, a secure connection between the fastening part 1 and the LED board 2 can be particularly suitably effected.
    In the figures 4 and 5, a second embodiment of an application according to the fastener 1 is outlined. Unless stated otherwise, the above statements also apply analogously with reference to this exemplary embodiment-as well as with reference to the following further exemplary embodiments. Also, the reference numerals are used analogously.
    In this example, the fastener 1 is a first piece I and a second piece II comprising formed, wherein the base portion 8 is part of the first piece I and the two resilient arms 4, 5 are components of the second piece II. In this case, the design is preferably such that the first piece I and the second piece II can be moved parallel to the plane E relative to one another, preferably can be displaced limitedly relative to each other. So the first piece I is floating on the second piece II. In this way it can be achieved that the two pieces I, II can be slightly moved against each other, so that any existing deviations between the LED board 2 and the lamp component 3 can be compensated. Thus, in particular ent speaking manufacturing tolerances can record.
    This design is therefore particularly suitable for compensating for different thermal expansions of the LED board 2 on the one hand and the luminaire component 3 on the other hand in the case of, for example, operational heating.
    For example, the second piece II may be formed as a holding frame in which the first piece I is floatingly mounted. The holding frame can be made of a bent sheet metal stamping, as well as the first piece.
    In the figures 6 and 7, a third embodiment of an application according fastener is outlined. In this example, the fastening element 1 comprises, in addition to the two resilient arms 4, 5, two further resilient arms 4 ', 5', which are designed analogously to the first-mentioned resilient arms 4, 5, but are arranged offset to the latter on the base region 8 , In the example shown, the two further resilient arms 4 ', 5' are located on a third straight line G1 'whose projection on the plane E with the projection of the first straight line G1 on the plane E includes a further angle ß, which is greater than 30 ° and is less than 150 °, preferably greater than 45 ° and less than 135 °, so for example 90 °. By this design, a particularly secure hold of the fastener 1 is achieved on the LED board 2.
    Fig. 7 shows the fastener 1 in a state attached to the LED board 2, and connected to the peg-like support member 10 of the lighting component 3. The fastener 1 can be moved into a corresponding opening of the LED board 2 snap , As a result, manufacturing tolerances can be added. By the four resilient arms 4, 5, 4 ', 5' it is, so to speak, in all directions particularly suitable secured against self-loosening.
    In Fig. 9 an example of a corresponding arrangement is sketched in perspective, showing the fastener 1 in a fixed to the LED board 2 and connected to the lamp component 3 state. The sketch shows an oblique view of the first surface area 21 of the LED board 2. LEDs 25 are arranged on the first surface area 21.
    Fig. 10 shows a corresponding sketch of this arrangement from a different angle, namely at an oblique view of the second surface area 22 of the LED board 2. As outlined, it can be in the luminaire component 3, for example, an optical element , For example, a lens element, act, which is designed to influence a light emitted by the LEDs 25 light. For example, the luminaire component can be designed as a cover.
    The luminaire component 3 is inserted in this example to assemble the assembly coming from the second side S2 of the plane E forth with the pin-like holding member 10 through the passage opening 9 therethrough. The spring tongues 11 are accordingly designed so that they extend obliquely to the first side S1 of the plane E, as also outlined in Figures 6 and 7. Characterized in that the fastening element 1 in this example, four resilient arms 4, 5, 4 ', 5', which press against the second surface portion 22 of the LED board 2, a particularly secure hold of the lamp component 3 at the LED Board 2 scored.
    In this arrangement, the LEDs 25 can be mounted on the LED board 2 from the second side S2, for example as SMDs (SMDs: surface-mount device) and also as the luminaire, advantageously with respect to the assembly. Component 3 can be mounted from the second side S2 ago. The fastener 1 is particularly suitable to be attached to the latter already in the production of the LED board 2.
    As shown in FIG. 6, in the third embodiment, the two abutment portions 6, 7 are designed such that they bulge outwards relative to the base portion 8 and with respect to the passage opening 9. As a result, the two other fe-reducing arms 4 ', 5' can be made particularly suitable.
    In addition, in the third embodiment, the fastening element 1 except the two contact areas 6, 7 still two other contact areas 6 ', 7', which are designed analogous to the first-mentioned investment areas 6, 7, but offset to the latter on the base area. 8 are arranged. In the example shown, the two further contact areas 6 ', 7' lie on a fourth straight line G2 'whose projection on the plane E with the projection of the second straight line G2 on the plane E includes an even wider angle γ that is greater than 30 ° and is less than 150 °, preferably greater than 45 ° and less than 135 °, so for example 90 °. As a result of this design, a particularly secure attachment of the fastening element 1 to the first surface region 21 of the LED board 2 is achieved.
    For a particularly secure hold of the fastening element 1 on the LED board 2, the design is preferably such that the four mentioned straight lines G1, G2, G1 ', G2' are oriented offset from one another. For example, it can be provided that the angle α between the projection of the first straight line G1 onto the plane E and the projection of the second straight line G2 onto the plane E is between 10 ° and 80 °, preferably between 25 ° and 65 °, particularly preferably between 40 ° and 50 °.
    In Fig. 8 is a perspective sketch of a variation of the third embodiment shown, in which the spring tongues 11 are designed such that they extend with respect to the plane E obliquely to the second side S2. In Fig. 9, such a fastener is provided with the reference numeral 1 'sketched.
    By said design of the spring tongues 11, the fastener 1 'is suitable for connection with a corresponding pin-like holding element 10' of a corresponding further lighting component 3 ', coming from the first side S1 of the plane E through the passage opening 9 therethrough is plugged. As indicated in FIGS. 9 and 10, the further luminaire component 3 'can be, for example, a carrier element or a housing element or a heat sink element.
    In Fig. 11, another example of a corresponding arrangement in the manner of an exploded view is sketched. Here, the luminaire component 3 is designed as an optical element and cover, which serves to cover the LED board 2.
    Of course, as shown in FIGS. 9, 10 and 11, each exemplarily illustrated, with a corresponding arrangement for the connection between the luminaire component 3 and the LED board 2, a plurality of corresponding fastening elements according to the application can be provided. Thus, in the sketched in Fig. 11 arrangement, for example, five fasteners and provided and accordingly on the lamp component five pin-like holding elements.
    A corresponding arrangement may in particular be part of an LED light.
    With the fastening element 1 according to the application, it is possible, in particular, for a corresponding arrangement to be assembled in an automated assembly process. In contrast, in the above-mentioned prior art, a manual workstation is required, on which a corresponding LED board must first be placed, then centered and then set several screws and must be specifically tightened so that there is still free play for thermal expansion.
    But even in the case of assembling a corresponding arrangement by hand, the fastener is advantageous because only a simple mating is required and this is easier to handle than the manufacture of a screw. In particular, with the attachment according to the fastener assembly without the aid of a tool allows.
    The attachment according to the fastener is suitable for use in high-speed placement machines. These can generally process different products and are thus well utilized and work very cheaply.
    In an SMD manufacturing process of the LED board 2, components such as the LEDs 25, terminals, plug contacts and various other components can be placed on a selectively applied solder paste by a high-speed placement machine and then soldered in a soldering oven. In this assembly process and according to the application fastening elements can be placed and snapped into corresponding punched holes of the LED board 2, so that they are connected with lateral movement clearance with the LED board 2. They then stand for receiving peg-shaped holding elements of the luminaire component 3, for example a cover, available and connect them to the LED board 2. During assembly so the fasteners must not be provided, since they already as it were part of the LED board 2 are. It follows: A simple placement and joining or mating is sufficient for the production of the connection between the LED board 2 and the luminaire component 3 or optionally the luminaire components 3, 3 '.
    Optionally, however, the fasteners can also be soldered and are thus firmly connected to the LED board 2. Optionally, the fastener 1 may also be designed so that the loading direction is also the mounting direction of the retaining pin or at the same time so that the retaining pin is received against the loading direction.
    12, a fourth exemplary embodiment of a fastening element according to the present invention is sketched, here designated by the reference numeral 1 ", the fastening element 1" being designed as an electrical contacting element in this embodiment. In Fig. 15, a corresponding LED board 2 is sketched with an LED 25. The LED board 2 has at least one electrical contact region 27 for a power supply of the LED 25.
    Furthermore, the LED board 2 has a lead-through opening 26 which is preferably formed directly adjacent to the electrical contact area 27 and which is intended to be penetrated by the fastening element 1 "In the example shown here, the at least one electrical Contact area 27 arranged on the same side of the LED board 2 as the LED 25, also referred to here as the "front" of the LED board 2.
    For fastening the fastening element 1 "to the LED board 2, the fastening element 1" has two solder contact regions 110, 111, which are provided to be electrically conductively connected to the at least one electrical contact region 27 of the LED board 2 be, in particular by means of a solder joint. Preferably, the two solder contact portions 110, 111 are formed lying in a plane and each on a lateral extension 15, 16 of the fastener 1 "arranged, wherein the two extensions 15, 16 in a normal projection of the fastener 1" on the plane E Seen laterally over the remaining fastening element 1 "extend, so can be achieved by the extensions 15, 16 in the attached state, a particularly secure hold of the fastener 1" on the LED board 2.
    Fig. 16 shows an oblique view of the front side opposite the back of the LED board 2, wherein the fastener 1 "already attached as intended to the LED board 2, in particular by means of a solder connection between the at least an electrical contact region 27 of the LED board 2 and the solder contact regions 110, 111 of the fastening element 1 ". The two extensions 15, 16 extend on the front side of the LED board 2 beyond the edge of the lead-through opening 26 so that they form a contact for the fastening element 1 "on the front side of the LED board 2, by the further passing through of the fastening element 1 "is prevented by the passage opening 26.
    Furthermore, the fastening element 1 "two resilient arms for a latching connection, here with the reference numerals 12 and 13, but in this case this latching connection between the fastener 1" and one, shown by way of example in Fig. 17 corresponding luminaire component provided, which may be in particular a plate-shaped support member for the LED board 2, for example in the form of a
    Aluminum sheet. The luminaire component 3 in this case has a corresponding lead-through opening 36, which is penetrated by the fastening element 1 "when the LED board 2 is connected to the luminaire component 3 as intended.
    The fastening element 1 "furthermore has an electrical connection region 14, in particular in the form of an electrical terminal, which is electrically conductively connected to at least one of the two solder contact regions 110, 111. The electrical connection region 14 protrudes accordingly, as do the two resilient arms 12, 13 through the lead-through opening 36 of the lamp component 3 or carrier element therethrough, in this way a comfortable connection with a power supply line or a connecting cable for powering the LED 25 is possible.
    In the connected state, the two resilient arms 12, 13 engage behind the luminaire component 3 and thus ensure that the LED circuit board 2 is held on the luminaire component 3 or on the carrier element.
    In the embodiment shown in FIG. 12, the two resilient arms 12, 13 are designed such that they automatically move inwardly through the lead-through opening 36 of the luminaire component 3 when passing through the fastening element 1 "and in the fully attached state to the outside snap, whereby the locking is obtained.
    In Fig. 13, a variant is shown, in which the two resilient arms 12, 13 are designed such that they must be compressed before passing through the passage opening 36 of the lamp component 3.
    However, the fastening element 1 "is also suitable, for example, for the case that the LED board 2 has no corresponding leadthrough opening 26. In this case, the fastening element 1" can be connected to the at least one electrical contact region 27 such that it can be connected by the front of the LED board 2 protrudes. In this case, it is particularly suitable, for example, for connecting the LED board 2 to a luminaire component in the form of an optical element for influencing a light emitted by the LED 25. The solder connection between the LED board 2 and the fastener 1 "allows a sufficiently secure hold, since only the weight of the LED board 2 must be worn and therefore no particularly high forces occur.
    In the fourth exemplary embodiment, the fastening element 1 "preferably comprises a housing made of an electrically non-conductive material, in particular a plastic, The two resilient arms 12, 13 are made of the electrically non-conductive material.
    However, as shown in Fig. 14, it may also be provided in principle that the fastening element, here denoted by the reference symbol T ", is made of an electrically conductive material, for example made of a sheet metal stamped part For example, as a ground contact.
    Also, the fastener according to the fourth embodiment is suitable for being attached to the LED board 2 in the course of the assembly of the LED board 2. As a result, the LED board 2 can be fixed to the luminaire component 3 or the carrier plate without the aid of a further fastening element, by simply snapping it on.
