    Field of invention
    The present invention relates to a light emitting diode (LED) lamp assembly. The present invention also relates to a method for manufacturing an LED lamp assembly.
    Background of the invention
    The use of LEDs for a lighting application is currently increasing. In lamps for standardized sockets in particular, such as the E22 or E26 sockets, previously used light sources such as filaments, fluorescent tubes and other luminescent materials are subsequently replaced by LEDs. This can reduce the energy consumption of the lamps.
    In prior art LED lamps, the LEDs are usually applied to a substrate, which may be a printed circuit board, for example. The LEDs can be soldered or otherwise attached to the circuit board. One or more circuit boards are fastened to a base of the lamp using fasteners such as screws or rivets. The base is provided with means for mechanically connecting the lamps to a socket and for establishing electrical contact with corresponding contacts of the socket for providing electrical energy for the lamp and thus for at least one LED thereof. Such lamps according to the prior art are e.g. B. known from the documents US 8 894 268 B2, US 8 704 432 B2, US 2014/005 600 181, US 2014/98 303 A1 and EP 25 277 308 A1.
    LED lamps according to the prior art are disadvantageous in that their assembly and in particular the attachment of the circuit board to the base are tedious, especially due to the fastening means used for it. Furthermore, the number of parts required for prior art lamps is quite large. Due to the complicated assembly and the large number of parts, it is difficult to achieve full automation of the production of LED lamps according to the prior art. Thus, manual steps are still involved in production. Therefore, the production of LED lamps according to the prior art is inefficient and causes high costs, which in turn leads to relatively high prices for the known LED lamps.
    Summary of the invention
    In view of the disadvantages of known LED lamps as described above, it is an object of the present invention to provide an LED lamp assembly which is easy to assemble, yet robust and which enables full automation of the production, or at least the manufacturing applications minimized and thus reduced the costs of LED lamps.
    According to the present invention, these objectives are achieved by the features of the independent patent claims. In addition, further advantageous embodiments follow from the dependent patent claims and the description.
    According to the present invention, the objectives set out above are achieved in an LED lamp arrangement in particular in that the arrangement comprises a base which is provided with a connecting part for connecting the arrangement with a socket of an electric lamp and with a holding part, the The connecting part and the holding part point in opposite directions which are substantially parallel to a central axis of the arrangement and comprise a substrate which carries at least one LED and has an attachment portion which is fastened to the holding part in a fully assembled state of the arrangement, wherein the holding part and the fastening section in the fully assembled state bear against one another in a plane which runs essentially parallel to the central axis.
    In a method mentioned at the beginning of the description, the objects set out above are achieved in that a base is provided with a connecting part for connecting the arrangement with a socket of an electric lamp and with a holding part, the connecting part and the holding part in opposite directions Show directions and run substantially parallel to a central axis of the arrangement, wherein a substrate carrying at least one LED is provided with a fastening portion for fastening the substrate to the holding part in a fully assembled state of the arrangement and wherein the holding part and the fastening portion in fully assembled state in a plane which runs essentially parallel to the central axis, abut one another.
    These solutions make it possible that the substrate and the base can be easily plugged together by being moved towards one another essentially parallel to the central axis. The holding part and the fastening section can be connected by a single sliding movement of the substrate relative to the base. Additional fastening means for fastening the substrate to the base can thus be omitted, especially when the substrate, in particular the fastening section thereof, is oriented perpendicular to the central axis. The fastening section and the holding part can wedge when they are connected to one another, so that a frictional connection and / or force connection is established between the substrate and the base.
    In other words, the substrate can be attached to the base by moving the substrate in an insertion direction of the arrangement towards the base. The fastening section of the substrate and the holding part of the base can be shaped and arranged in such a way that the substrate is fastened directly to the base by means of a friction fit and / or a force fit. A connecting part for connecting the arrangement to a desired standardized electrical lamp socket or fitting and for extending it along the insertion direction for at least a partial insertion of the connecting part into the socket or fitting can be provided on the base.
    In the following paragraphs further improvements to the arrangement and method according to the present invention are described. The additional enhancements can be combined independently, depending on whether a particular benefit of a particular improvement is required in a specific case.
    According to a first advantageous improvement of the arrangement, the substrate in the fully assembled state can at least partially protrude into the holding part. In particular, the fastening section can protrude into the holding part and / or the connecting part in the insertion direction. Thus, the fastening section and the holding part can be brought into contact with one another in a simple manner in a plane which runs essentially parallel to the central axis. At the same time, the overall dimensions of the arrangement, in particular measured parallel to the central axis or a height direction of the arrangement, can be minimized.
    In the fully assembled state, the substrate and the connecting part can be superimposed in a radial direction of the arrangement, the radial direction running essentially perpendicularly away from the central axis. The holding part can at least partially overlap with the connecting part in alignment along the radial direction. In other words, the fastening section can be pushed over an end region of the holding part in a direction which runs opposite to the direction of insertion. This makes it easier to bring the fastening section into engagement with the holding part and to establish a force fit and / or friction fit between them.
    In the fully assembled state, the holding part can be arranged at least partially in a recess which is formed within an extension of the base. Alternatively and / or additionally, an outer circumference of this extension can form at least part of the connecting part. As a result, the overall dimensions of the arrangement, in particular in the height direction, can be reduced. Furthermore, it is made possible to establish electrical contact between the substrate, in particular the fastening section thereof, and the connecting part, since the distance between them is reduced in comparison to arrangements according to the prior art.
    The fastening section can at least partially engage positively in the holding part. By producing a force fit, frictional fit and / or form fit between the fastening section and the holding part, the substrate can be reliably fastened to the base. The form fit is particularly helpful in avoiding undesirable rotational movements of the substrate relative to the base about the central axis. In order to allow an adequate fit between the fastening portion and the holding part, the substrate can be provided with a slot which runs along the height direction and opens in the insertion direction so that a wedge or coding means can penetrate into the slot while the substrate is in operation is connected to the base.
    At least one cross section of the fastening portion can have a polygonal shape in a projection along the central axis and / or the insertion direction. A polygonal shape can help to create a form fit between the substrate and the base. For example, the cross-section can be hexagonal in shape. In either case, the substrate, particularly the attachment portion thereof, can be tubular. A lighting section which is arranged above the fastening section can also have a tubular shape and can provide several side surfaces for receiving LEDs. The luminous section can merge into the fastening section, so that they are aligned with one another in a projection along the insertion direction and / or the height direction. In addition, the substrate can be provided with a flat upper side or cover, which provides a further surface for receiving at least one LED. Each of the sides and the top of the substrate can carry at least one LED.
    At least one contact surface for the electrical connection of the substrate to the connecting part can be formed on the fastening section. In the fully assembled state, the at least one contact surface can run along a plane which runs essentially parallel to the central axis. The at least one contact surface can be provided on the fastening section of the substrate. Thus, when the fastening section for fastening the substrate to the base is brought into contact with the holding section, an electrical contact with the substrate can be made at the same time in that at least one contact surface is contacted.
    At least one fastening surface for holding the substrate and at least one contact surface can be formed on the fastening section in such a way that they are arranged next to one another along an outer circumference and / or inner circumference of the substrate. It can thus be ensured that a multiplicity of fastening surfaces and a multiplicity of contact surfaces are formed on the fastening section in such a way that they can rest against the holding part at the same time when the substrate is brought into engagement with the base.
    A multiplicity of contact surfaces and fastening surfaces can be arranged in an alternating manner along the outer circumference and / or inner circumference. Thus, at least one holding surface can be arranged between two contact surfaces with different predefined electrical polarizations. This helps to prevent a faulty connection between substrate and base. The substrate, in particular the fastening section thereof, can be shaped such that it can only be joined to the base in a predefined orientation with respect to the holding part. This alignment can be defined, for example, by a slot or other coding means that help prevent the substrate and socket from being joined together incorrectly.
    The arrangement can further comprise at least one first contact element which, in the fully assembled state, is at least partially arranged between the fastening section and the holding part, so that it makes electrical contact with the substrate. The contact element can, for. B. be formed from an electrically conductive polymer and / or an / an electrically conductive metal or metal alloy. However, a polymer has the advantage over metals that it can be more cost effective in terms of manufacturing technology and resources. The contact element can abut the holding surface and / or contacting surface in order to help immobilize the substrate relative to the base.
    The at least one first contact element can comprise a fitting part which is shaped complementarily to the fastening section and / or holding part. Thus, at least two of the substrate, base and at least one first contact element can be formed complementary to one another. In the fully assembled state, the substrate, in particular the fastening section thereof, the base, in particular the holding part thereof, and the at least one first contact element, in particular the fitting part thereof, can engage in one another in a form-fitting manner. The fitting part can be fitted flush between the fastening portion and the holding part. In other words, the fitting part can be sandwiched between the fastening section and the holding part in such a way that a compact arrangement of substrate, base and contact element is achieved.
    A first electrical contact of the arrangement, which in the fully assembled state is accessible from outside the arrangement on the connecting part, can be formed on the at least one first contact element. The first electrical contact can be a so-called hot contact. The at least one first contact element can comprise a conductor part which can connect the fitting part to the electrical contact in an electrically conductive manner. The fitting part, the conductive part and / or the contact element can be formed integrally on the at least one first contact element. The at least one first contact element can be formed from and / or consist of just a single material, such as a conductive polymer, as already explained above.
    The arrangement can further comprise at least one second contact element which, in the fully assembled state, can be arranged at least partially between the fastening section and the holding part, so that it makes electrical contact with the substrate. This allows a second electrical contact, e.g. B. a ground contact or cold contact may be provided for electrically connecting the assembly to a socket. The at least one second contact element can be shaped and arranged similarly to the at least one first contact element. The at least one first and / or second contact element can be provided with threads or the like, as desired, in order to connect the arrangement to a socket, e.g. B. in which the arrangement is screwed into the socket in a known manner in order to fasten the arrangement and at the same time to produce an electrical contact between the arrangement and corresponding electrical mating contacts within the socket.
    The arrangement can further comprise at least one translucent dome which can be attached to the base in the fully assembled state so that it can enclose the substrate. The dome and the base can engage in one another in a form-fitting manner. The dome can be provided with a fastening structure which can include collars, stops, walls and / or lateral supports or the like in order to restrict and / or prevent movements of the substrate relative to the base.
    In the case of the method mentioned at the beginning of the description, the solution according to the invention can be further improved above in relation to the features mentioned above. A person skilled in the art will have no difficulty in understanding that the implementation of each device and device feature set forth above can be interpreted as at least one advantageous method step which can be selected as desired in order to simplify and / or manufacture the arrangement to enable the provision of an arrangement with the desired technical specifications.
    For example, the substrate can be attached to the holding part along the insertion direction in which the connecting part is to be inserted into a socket. The fastening section of the substrate can be provided with a holding surface which is arranged essentially parallel to the insertion direction. The fastening section can be brought into engagement with the base of the arrangement in that the substrate is moved in the direction of insertion towards the base, whereby the substrate, the base and / or at least one contact element of the arrangement are wedged and / or positively connected to one another in relation to one another can. As a result, the substrate can be attached to the base at the same time and an electrical contact can be established between the base and the substrate.

    Detailed description of the preferred embodiments
    Fig. 1 shows a first embodiment of an LED lamp arrangement 1 according to the present invention in a schematic perspective exploded view. The arrangement 1 extends along a lateral direction X, a transverse direction Y and a height direction Z, which together form a Cartesian coordinate system, i. H. the lateral direction X extends perpendicular to the transverse direction Y and to the height direction Z, which extends perpendicular to the transverse direction Y. In Fig. 1, the arrangement 1 is shown in a non-assembled state U, in which all elements can be separated from one another and are ready for assembly.
    The arrangement 1 comprises a base 2, a substrate 3, a first contact element 4, a second contact element 5 and a translucent dome 6, which are spaced from one another in the height direction Z. A central axis or central axis M of the arrangement 1 runs essentially parallel to the height direction Z. An insertion direction I of the arrangement 1 runs essentially parallel to the central axis M and can be superimposed therewith. In the insertion direction I, the arrangement 1 can be inserted into a lamp holder (not shown). Furthermore, the substrate 3, the first contact element 4 and the dome 6 can be brought together with the base 2 in the insertion direction I, while the second contact element 5 can be brought together with the base 2 in a direction that runs opposite to the insertion direction I.
    The base 2 has a connecting part 20 which is designed to connect the arrangement 1 to an electrical lamp socket which, for. B. can be a standardized E26 socket, and with a holding part 21 for holding the substrate 3. The base furthermore comprises a flange 22 which surrounds the holding part 21 and is designed to hold the dome 6. The connecting part 20 protrudes from the flange 22 in the insertion direction I and comprises a pin 23 which is partially surrounded on the circumferential side by a collar 24. The holding part 21 can be accessed from below the flange 22 through an opening 24a in the collar, so that the second contact element 5 can protrude from outside the arrangement 1 through the base in a fully assembled state W of the arrangement 1 into the arrangement 1 (see FIG Figs. 2 to 12). The flange 22 can have an edge 22a. At least one latching element 22b can be formed on the flange 22 and in particular on the edge 22a in order to latch the dome 62 in the fully assembled state W on the base.
    The holding part 21 comprises a holder 25 for holding the substrate 3. The holder 25 is arranged in a recess 26 and can be designed so that an upper edge 25a of the holder 25 is substantially in one plane with an edge 26a of the recess 26 extending along the lateral direction X and the transverse direction Y, can be oriented, d. H. that they are arranged essentially at the same level. The holder 25 may have a tubular shape and may be coaxial with the recess 26 having a shape e.g. B. may have a round cross-section, be arranged. The holder 25 can be provided with a plurality of holding surfaces 25b which are separated from one another by corners 25c. The holding surfaces 25b and corners 25c can have regular and / or equal lengths or angles, so that the holder 25 has a polygonal cross section in a projection along the insertion direction I. The holder 25 can also be provided with a cutout 25d which opens in the insertion direction I and enables the first contact element 4 to be received within the recess 26.
    The substrate 3 can, for. B. be a circuit board, which may have a tubular shape. The substrate 3 has a fastening section 30 and a luminous section 31. A cover 32 can be arranged on the top of the substrate 3, in particular the luminous section 31. The luminous section 31, e.g. B. the outer circumference thereof and / or the cover 32 can carry at least one LED. The fastening portion 30 may have a lower edge 30a and a plurality of inner fastening surfaces 30b, which may be separated from one another by corners 30c in the same or a similar manner as the holding surfaces 25b of the holder 25. The fastening surfaces 30b can be distributed uniformly along an inner circumference of the substrate 3, in particular the fastening section 30. A notch or a slot 30d can be formed in the substrate 3, in particular in the fastening section 30. The slot 30 may extend upwardly from the lower edge 30a, e.g. B. in a wall section of the substrate 3, so that a correct alignment of the substrate 3 with respect to the base 2 is defined. In other words, the slot 30d can help to encode the alignment of the substrate 3 with respect to the base 2, so that an incorrect connection of the substrate 3 and the base 2 is prevented. In addition, other fastening surfaces 30e can be arranged along an outer circumference of the substrate 3, in particular the fastening section 30, and can also be used to fasten the substrate 3 to the base.
    In order to produce an electrical contact with the LEDs which are attached to the substrate 3, the substrate can be provided with contact surfaces 33, which can be arranged similarly to the fastening surfaces 30b, 30e. The contact surfaces 33 can be arranged along the outer circumference of the substrate 3. In the exemplary embodiment shown in FIG. 1, two contact surfaces 22, which are assigned to the second contact element 5, can be arranged in the fastening section 30. Further contact surfaces 34 can be provided in order to establish electrical contact with the first contact element 4 (see FIG. 11).
    The first contact element 4 can comprise an electrical contact 40, a conductor part 41 and a fitting part 42. The electrical contact 40 can be designed as a contact pin and / or contact point which protrudes from the contact element 4 in the insertion direction I. The electrical contact 40 can be formed on an end region of a leg 41a of the conductor part 41. The leg 41a can be supported by a strut 41b which extends substantially perpendicularly away from the fitting part 42, i. H. runs essentially perpendicular to the insertion direction, in the insertion direction I downwards. The fitting part 42 of the first contact element 4 can have outer fitting surfaces 43 which can be shaped complementary to the inner circumference of the holding part 21, in particular to the recess 26 thereof. Inner mating surfaces 44 of the contact element 4 can be shaped and arranged in such a way that they rest flush against the further contact surfaces 34 in the fully assembled state W.
    The second contact element 5 can have a second electrical contact 50 and a second conductor part 51, which can be a part of a second fitting part 52 with an outer fitting surface 53 and at least one inner fitting surface 54 or can be integrated into it. The second electrical contact 50 can, for. B. be designed as a thread that corresponds to the B26 standard. The second conductor part 51, which extends upward from the second electrical contact 50 counter to the insertion direction I, can be omitted when the second electrical contact 50 is joined to the fitting part 52, as shown here. The outer fitting surface 53 can be shaped complementary to the inner circumference of the recess 26. The second inner fitting surface 54 can be shaped complementary to the outer circumference of the substrate 3 in the area of the contact surfaces 33. The second inner fitting surfaces 54 can be shaped and arranged in such a way that, in the fully assembled state W, they rest flush on the outer circumference of the substrate 3 in the area of the contact surfaces 33.
    The dome 6 can have a tubular body 50 with a lower edge portion 61 which surrounds an opening 62 of the tubular body 60 which opens in the insertion direction I in order to be able to insert the substrate 3 in the dome 6 record. Mating latching means 63 can be arranged in the area of the lower edge part 61 and configured such that they interact with the latching elements 22b which are formed on the base 2 in order to fasten the dome 6 to the base 2 in the fully assembled state.
    2 to 5 show the arrangement 1 in the fully assembled state W in a schematic front view, schematic side view, schematic bottom view and schematic top view. In order to achieve the fully assembled state W, a plurality of pre-assembled states V can be defined between the unassembled state U and the fully assembled state W. In any case, in the fully assembled state W, the base 2, the substrate 3, the first contact element 4, the second contact element 5 and the dome 6 are connected to one another so that they essentially form a stable LED lamp.
    As can be seen in particular in FIGS. 2 and 3, the first electrical contact 40 protrudes downward from the pin 23 in a lower end region of the arrangement 1. The second contact element 5 is fastened around the collar 24 and provides the second electrical contact 50. The dome 6 is attached to the flange 22 of the base 2, the counter-locking elements 63 of the dome being latched into the locking elements 22b on the socket, so that the dome 6 is releasably fastened to the socket 2 again.
    FIG. 6 shows the arrangement 1 in the completely assembled state W in a schematic cross-sectional view along the cross-sectional line A-A shown in FIG. 3. It is evident here that the fastening part 30 of the substrate 3 is inserted into the recess 26 in the completely assembled state W, so that the holder 25 engages in the fastening part 30. The holding surfaces 25b are aligned with the inner fastening surfaces 30b of the substrate 3 and bear against them. In other words, the inner fastening surfaces 30b of the substrate 3 lie flush against the holding surfaces 25b of the base 2. As a result, the fastening section 30, in particular the inner fastening surfaces 30b, with the holding part 21, in particular the holding surfaces 25b of the holder 25, are superimposed in a projection along the radial direction R of the arrangement 1. In a similar way, the inner fitting surfaces 44 of the first contact element 4 rest on further contact surfaces 34 of the substrate 3.
    Thus, the substrate 3 is wedged with its fastening section between the holder 25 and the first contact element 4 and protrudes from there longitudinally upwards without it having to be additionally held in the area of the cover 32 within the dome 6. These are possible ways in which the holding part 21 and the fastening section 30, in the completely assembled state W, can rest against one another in at least one of several possible planes which run essentially parallel to the central axis M. The number of such planes is not particularly limited since their surface normal vectors can simply be perpendicular to the central axis M, e.g. B. parallel to and / or superimposed with the corresponding radial direction R.
    Fig. 7 shows a detail B shown in Fig. 6. Here it becomes obvious how the tip 6 is locked in the fully assembled state W on the base. The counter-locking means 63 in the form of projections or locking lugs protrude into the locking elements 22b, which can be formed as indentations, recesses, through holes or the like in the edge 22a. The lower edge part 61 of the dome 6 can be surrounded circumferentially by the edge 22a and can thus be introduced into the edge 22a on the flange in the insertion direction I, so that the dome 6 is held firmly on the base 2.
    FIG. 8 shows the arrangement 1 in the fully assembled state W in a schematic cross-sectional view along the cross-sectional line C-C shown in FIG. 2. It is evident here that in the area of the connecting part 20 the holding part 21, the first contact element 4 and the second contact element 5 together form a connector 100 of the arrangement 1. The connector 100 can protrude downwards from the flange 22 in the insertion direction I and enables the mechanical and electrical connection of the arrangement to a socket (not shown).
    The first electrical contact 40 protrudes below the pin 23 in the insertion direction I. The leg 41a extends upward from the first electrical contact 40 and converges with the strut 41b, which connects the leg 41a to the fitting part 42, which can be arranged between the inner circumference of the recess 25 and the fastening portion 30. The electrical contact 40 enables an electrical connection of the arrangement with a first electrical mating contact of the socket.
    The fitting part 42 can be wedged between the walls of the recess 26 and the fastening section 30 in such a way that the inner fitting surfaces 44 are flush with the substrate 3, in particular the contact surfaces 34 thereof, and the outer fitting surfaces 43 are flush with the inner circumference of the recess 26 issue. These are possible ways in which the holding part 21 and the fastening section 30, in the fully assembled state W, can rest against one another in at least one of several possible planes which run essentially parallel to the central axis M. The number of these planes is not particularly limited since their surface normal vectors can simply be perpendicular to the central axis M, e.g. B. parallel to and / or superimposed with the corresponding radial direction R.
    The second contact element 5 can be in engagement with the connecting part 20 of the base in such a way that the second fitting part 52 is inserted into the opening 24a of the collar 24. As a result, the second inner fitting surfaces 54 can rest flush against the holding surfaces 25b of the holder 25 and the contact surfaces 33 of the substrate 3. The second electrical contact 50 can be formed as a thread in order to enable a mechanical and electrical connection from the arrangement 1 to a second mating contact element within the socket. Additional mechanical stability in the case of an installation comprising the arrangement 1 within a socket can be provided by the lower surface of the flange 22, which essentially points in the insertion direction I and enables the arrangement to abut against an upper edge of the socket. Additional mechanical stability can be provided by the pin 23, which can protrude into a complementarily shaped opening within the mount.
    FIG. 9 is a detail D shown in FIG. 8. It becomes evident here that the shoulder 43a is formed on the outer fitting surface 43 of the fitting part 42 and that a projection 26b is formed within the recess 26. As a result, the first contact element 4 engages on the holding part 21, so that movements of the first contact element 4 with respect to the base 2 against the insertion direction I are prevented.
    Fig. 10 shows a shown in Fig. 8 detail E. Here it becomes apparent that a bulge 24b is formed within the opening 24a of the collar 24, which protrudes from a wall part of the opening 24a against the radial direction R and into which second fitting part 52 of the second contact element 5 engages. The second fitting part 52 is provided with an indentation at an upper end region in which a nose 53a is formed on the outside of the second fitting part 52. The nose 53a overlaps the bulge 24b and thereby prevents movements of the second contact element 5 relative to the base 2 in the insertion direction I. In other words, the second contact element 5 engages in the fully assembled state W with the help of the bulge 24b and the nose 53, which ensure that the contact element 5 overlaps the base 2 in one alignment in a projection along the insertion direction I, into the base 2, whereby a form fit between the second contact element 5 and the base 2 is produced.
    FIG. 11 shows a schematic cross-sectional view of the arrangement 1 in the completely assembled state W along the cross-sectional line F-F illustrated in FIG. 5. It is evident here that on the side of the first contact element 4, in particular the fitting part 42 thereof, the fastening section 30 of the substrate 3 can be introduced like a sandwich between the holder 25 and the first contact element 4. The inner fastening surfaces 30g of the substrate 3 can rest flush against the holding surfaces 25b of the holder. The outer contact surfaces 34 can lie flush against the inner fitting surfaces 44 of the contact element 4. These are possible ways in which the holding part 21 and the fastening section 30, in the fully assembled state W, can lie against one another in at least one of several possible planes that run essentially parallel to the central axis M. The number of these planes is not particularly limited since their normal surface vectors can simply be perpendicular to the central axis M, e.g. B. parallel to and / or superimposed with the corresponding radial direction R.
    The contact element 4, in particular the fitting part 42 thereof, can be sandwiched between the fastening section 30 and the wall of the recess 26. While the inner fitting surfaces 44 of the contact element 4 can rest flush on the fastening section 30, the outer fitting surfaces 43 of the fitting part 42 can rest flush on the inner wall of the recess 26. The fitting part 42 of the first contact element 4 can be electrically insulated from the second contact element 5, which surrounds the holding part 21, by the collar 24 of the connecting part 20.
    On the side of the connecting part 20 of the first contact element 4 opposite the fitting part 42 with respect to the central axis M, the substrate 3, in particular the fastening portion 30 thereof, can be sandwiched between the second fitting part 52 of the second contact element 5 and the holder 25. The inner fastening surfaces 30b of the substrate 3 can be flush with the holding surfaces 25b of the holder 25, while the inner fitting surfaces 54 of the second contact element 5, in particular the fitting part 52 thereof, are flush with the contact surfaces 33, 34 and / or fastening surfaces 33b, 33e of the substrate 3 can apply.
    Since the base 2, the substrate 3, the first contact element 4 and the second contact element 5 all overlap in the radial direction R in the area of the connecting portion 30, the substrate 3 is held within the holding part 21 and the connector 100 has high stability. The substrate 3 can be viewed as being wedged within the holding part 21 and thus held on the base 2 by frictional engagement and / or force-locking. The connecting part 20 and the holding part 21 can overlap, i.e. H. they can be superimposed in the radial direction R.
    12 shows a schematic perspective exploded view of an LED lamp arrangement 1 'according to a further embodiment of the present invention. For the sake of brevity, only the differences between the arrangement 1 'and the arrangement 1 are explained in detail below. The arrangement 1 'can comprise a substrate 3 and a dome 6, which can have the same configuration as the substrate 3 and the dome 6 which are used in the arrangement 1. The arrangement 1 'can, however, comprise a base 2', a first contact element 4 'and a second contact element 5', which enable the arrangement 1 'to be connected to various sockets (not shown) like the arrangement 1. In particular, the arrangement 1 'can be designed so that it is compatible with so-called bayonet sockets, such as the standardized B22 socket.
    13 to 16 show the arrangement V in the fully assembled state W in a schematic front view, a schematic side view, a schematic bottom view and a schematic top view, respectively. In contrast to arrangement 1, arrangement 1 'can have a connector 100' which is suitable for bayonet sockets and / or couplings. For this purpose, the connector 100 'can be provided with two pins 27 which protrude laterally in the radial direction R from a connecting part 20' of the base 2 'on opposite sides thereof. Furthermore, two electrical contacts 40 ', 50', which can be formed on the contact elements 4 'or 5', protrude downward from the connecting part 20 'in the insertion direction, so that they protrude below a base 28' of the connecting part 20 '.
    To fit the contact elements 4 'and 5' on the base 2 ', the contact elements 4' and 5 'can be provided with an extension 45 or an extension 55. Distal end regions of the extensions 45 and 55 can each be provided with a bead 46 and 56, respectively. The beads 46 and 56 can be shaped to complement recesses 25e, which are shaped in a flange 22 'of the base 2 *. In the fully assembled state W, the beads 46 and 56 of the contact element 4 'and of the contact element 5' can protrude into the recesses 22c formed on the base 2 '.
    Furthermore, a holding part 21 'of the base 2' can comprise a recess 26 'which is similar to that which is formed in the base 2 of the arrangement 1. In contrast to the holding part 21 of the base 2, the holding part 21 'of the base 2 can, however, comprise two holders 25' which can have two holding surfaces 25b '. The holding surfaces 25 'can be connected to one another by a wall 25e, which helps stabilize the holder 25'.
    18 shows a detail B shown in FIG. 17. It is evident here that the beads 46, 56 taper in the insertion direction I, so that they can be wedged within the bulges 22 in order to provide a frictional connection and / or to provide frictional engagement of the contact elements 4 ', 5' on the base 2 '. It is also evident that the dome 6 of the arrangement 1 'is similar to the arrangement 1 with the aid of latching means 22a and counter-latching means 63 in a manner that is described above with reference to the arrangement 1, shown in FIGS. 1 to 11, on Base 2 'is locked.
    19 shows the arrangement 1 in the completely assembled state W in a schematic cross-sectional view along the cross-sectional line C-C shown in FIG. The contact elements 40 'and 50' can be inserted into the recess 26 in such a way that the outer fitting surfaces 43 'and 53' are flush with the inner circumference of the recess 26. The contact 40 'and 50' can protrude through corresponding through-holes which are formed within the base 28 'of the connecting part 20'.
    Fig. 20 shows a shown in Fig. 19 detail D. Here it becomes apparent how the electrical contact 40 'from the inside of the arrangement 1', in particular the connecting part 20 ', through a hole 29 in the bottom 28' to the outside of the Arrangement 1 'runs. A conductor part 41 'connects the electrical contact 40' with the fitting part 42 'of the contact element 4'. The electrical contact 40 'can have a contact recess 47 on its side in the direction pointing away from the insertion direction I.
    21 shows the arrangement 1 'in the completely assembled state W in a schematic cross-sectional view along the cross-sectional line E-E shown in FIG. 16. It is evident here that the fastening section 30 of the substrate 3 can be sandwiched on one side between one of the holders 25 'and the contact element 4' and on another side between one of the holders 25 'and the second contact element 5'. The inner fastening surface 30b can lie flush against the holding surface 25b, while the further contact surface 34 can lie flush against the inner mating surface 44 'of the first contact element 4'. The fitting part 42 'of the first contact element 4' can be sandwiched between the substrate 3 and the wall of the recess 26 '. The outer fitting surface 43 'can lie flush with the inner circumference of the recess 26', these are possible ways in which the holding part 21 'and the fastening section 30 in the fully assembled state W in at least one of several possible planes that are essentially parallel to the central axis M run, lie against one another. The number of these planes is not particularly limited since their surface normal vectors can simply be perpendicular to the central axis M, e.g. B. parallel to and / or superimposed with the corresponding radial direction R.
    On the other hand, the fastening section 30 can be sandwiched between the holder 25 'and the contact element 5'. The inner fastening surface 33 can lie flush against the holding surface 25 '. These are possible ways in which the holding part 21 'and the fastening section 30, in the fully assembled state W, bear against one another in at least one of several possible planes which run essentially parallel to the central axis M. The number of these planes is not particularly limited since their normal surface normal vectors can simply be perpendicular to the central axis M, e.g. B. parallel to and / or superimposed with the corresponding radial direction R.
    The contact surface 33 can lie flush against the outer fitting surface 54 'of the contact element 5'. The fitting part 52 'of the second contact element 5' can be sandwiched between the fastening section 30 and the inner circumference of the recess 26 '. The outer fitting surface 53 'can be flush with the inner circumference of the recess 26'. The lower edge 30a of the fastening section 30 can be supported on the bottom 28 'of the recess 26'. The substrate 3 can thus be immobilized in all directions by being held firmly on the fastening section 30 in the holding part 21 '.
    Therefore, the substrate 3 of the arrangement 1 ', similar to what was set out above in connection with the arrangement 1, can extend from the holder 25' longitudinally upwards along the central axis M within the dome 6 without being connected thereto to be. The connecting section 30 and the holding part 21 'can overlap, d. H. they can lie one above the other in the radial direction R. In the area of the cover 32, no further fastening structure is required on the dome in order to securely fasten the substrate 3.
