Description

description

Field of the Invention The present invention relates to a light emitting diode (LED) lamp assembly. Further, the present invention relates to a method of manufacturing an LED lamp assembly.

Background of the Invention The use of LEDs for a lighting application is currently increasing. Especially in lamps for standardized versions, such as the versions E22 or E26, previously used light sources such as filaments, fluorescent tubes and other luminescent materials are replaced by LEDs in the sequence. This can reduce the energy consumption of the lamps.

In LED lamps of the prior art, the LEDs are usually applied to a substrate, which may be, for example, a printed circuit board. The LEDs may be soldered or otherwise attached to the circuit board. One or more circuit boards are attached to a base of the lamp by fasteners such as screws or rivets. The socket is provided with means for mechanically connecting the lamps to a socket and making electrical contact with corresponding contacts of the socket for providing electrical energy to the lamp and thus for at least one LED thereof. Such lamps according to the prior art are e.g. 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 particularly cumbersome due to the fasteners used therefor. Furthermore, the number of parts required for prior art lamps is quite high. Due to the complicated assembly and the high number of parts, full automation of the production of LED lamps according to the prior art can be difficult to achieve. Thus, manual steps are still involved in the production. Therefore, the manufacture of LED lamps in 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 and yet robust and which fully automates production allows or at least minimizes manufacturing costs and thus reduces the cost of LED lamps.

According to the present invention, these objects are achieved by the features of the independent claims. In addition, further advantageous embodiments follow from the dependent claims and the description.

According to the present invention, the above-stated objects are achieved in an LED lamp arrangement, in particular in that the arrangement comprises a socket which is provided with a connecting part for connecting the arrangement to a socket of an electric lamp and with a holding part, wherein the connecting part and the holding part have in opposite directions, which extend substantially parallel to a central axis of the arrangement, and a substrate which carries at least one LED and has a fixing portion which is fixed to the holding part in a fully assembled state of the arrangement in which, in the fully assembled state, the holding part and the fastening section 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 by providing a base with a connection part for connecting the arrangement to a socket of an electric lamp and with a holding part, the connecting part and the holding part being in opposite directions and substantially parallel to a central axis of the assembly, wherein a substrate supporting at least one LED is provided with a mounting portion for securing the substrate to the support member in a fully assembled condition of the assembly, and wherein the support member and the mounting portion are fully engaged assembled state in a plane that is substantially parallel to the central axis, abut one another.

These solutions enable the substrate and pedestal to be easily mated by moving toward one another substantially parallel to the central axis. The holding part and the attachment portion can be connected by a single sliding movement of the substrate relative to the base. Thus, additional attachment means for securing the substrate to the pedestal may be eliminated, especially if the substrate, particularly the attachment portion thereof, is oriented perpendicular to the central axis. The attachment portion and the retention member may become wedged when joined together to provide frictional engagement and / or traction between the substrate and the socket.

In other words, by moving the substrate in an insertion direction of the assembly, the substrate may be attached to the pedestal on the pedestal. The mounting portion of the substrate and the holding portion of the base may be formed and arranged so that the substrate is attached directly to the base by frictional engagement and / or frictional connection. A connector for connecting the assembly to a desired standardized electrical lamp socket or fitting and for extending along the direction of insertion for at least partially inserting the connector into the socket or fitting may be provided on the socket.

In the following paragraphs further improvements of the arrangement and the method according to the present invention will be described. The additional enhancements can be combined independently depending on whether a particular benefit of a particular enhancement is required in a specific case.

After a first advantageous improvement of the arrangement, the substrate may protrude in the fully assembled state at least partially in the holding part. In particular, the attachment portion may protrude in the insertion direction in the holding part and / or the connecting part. Thus, the fixing portion and the holding part can be easily abutted against each other in a plane substantially 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 may be superimposed in a radial direction of the arrangement, the radial direction extending substantially perpendicularly away from the central axis. The holding part may at least partially overlap with the connecting part in an alignment along the radial direction. In other words, the attachment portion may be slid over an end portion of the support member in a direction opposite to the insertion direction. This makes it easier to bring the attachment portion with the holding part in engagement and produce a frictional connection and / or frictional engagement between them.

In the fully assembled state, the holding part can be at least partially disposed in a recess which is formed within an extension of the base. Alternatively and / or additionally, an outer circumference of this extension may 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. Further, it becomes possible to make electrical contact between the substrate, particularly the fixing portion thereof, and the connection part because the distance therebetween is reduced as compared with prior art arrangements.

The attachment portion may engage at least partially positively in the holding part. By producing a frictional connection, frictional engagement and / or positive connection between the fastening section and the holding part, the substrate can be reliably fastened to the base. The positive connection is particularly helpful in preventing unwanted rotational movements of the substrate relative to the base about the central axis. In order to allow a proper fit between the mounting portion and the holding part, the substrate may be provided with a slit 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 with connected to the socket.

At least one cross-section of the attachment portion may have a polygonal shape in a projection along the central axis and / or the insertion direction. A polygonal shape may help to make a positive connection between the substrate and the base. For example, the cross section may have a hexagonal shape. In any case, the substrate, in particular the attachment portion thereof, may be tubular. A luminescent portion disposed over the attachment portion may also have a tubular shape and may provide a plurality of side surfaces for receiving LEDs. The luminous portion may transition into the fixing portion, so that they are aligned with each other in a projection along the insertion direction and / or the height direction. Additionally, the substrate may be provided with a flat top or cover providing another surface for receiving at least one LED. Each of the sides and top of the substrate may carry at least one LED.

At least one contact surface for the electrical connection of the substrate to the connecting part may be formed on the attachment portion. In the fully assembled state, the at least one contact surface may extend along a plane that is substantially parallel to the central axis. The at least one contact surface may be provided on the attachment portion of the substrate. Thus, when the attachment portion for attaching the substrate to the pedestal is brought into abutment with the support portion, electrical contact with the substrate can be made simultaneously by contacting at least one contact surface.

At least one attachment surface for holding the substrate and at least one contact surface may be formed on the attachment portion so that they are arranged side by side along an outer circumference and / or inner circumference of the substrate. Thus, it can be ensured that a plurality of attachment surfaces and a plurality of contact surfaces are formed on the attachment portion so that they can simultaneously abut the holding part when the substrate is brought into engagement with the base.

A plurality of contact surfaces and attachment surfaces may be arranged along the outer circumference and / or inner circumference in an alternating manner. 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 of substrate and socket. The substrate, in particular the attachment portion thereof, may be shaped such that it can be assembled with the base only in a predefined orientation with respect to the holding part. This alignment may be defined, for example, by a slit or other coding means that help prevent substrate and socket mismatching.

The arrangement may further comprise at least a first contact element, which is arranged in the fully assembled state at least partially between the mounting portion and the holding part, so that it makes electrical contact with the substrate. The contact element may e.g. be formed of an electrically conductive polymer and / or one / 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 may abut the support surface and / or contacting surface to help immobilize the substrate with respect to the pedestal.

The at least one first contact element may comprise a fitting part which is formed complementary to the fastening portion and / or holding part. Thus, at least two of substrate, socket and at least one first contact element may be formed complementary to each other. In the fully assembled state, the substrate, in particular the attachment portion 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 between the fastening portion and the holding part may be sandwiched such that a compact arrangement of substrate, base and contact element is effected.

A first electrical contact of the arrangement, which is accessible in the fully assembled state from outside the arrangement of the connecting part, may be formed on the at least one first contact element. The first electrical contact may be a so-called hot contact. The at least one first contact element may 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 may be integrally formed on the at least one first contact element. The at least one first contact element can be formed from and / or consist of only a single material, such as a conductive polymer, as already explained above.

The assembly may further comprise at least a second contact element, which may be arranged in the fully assembled state at least partially between the mounting portion and the holding part, so that it makes electrical contact with the substrate. Thereby, a second electrical contact, e.g. a ground contact or cold contact to be provided for electrically connecting the assembly to a socket. The at least one second contact element may be formed and arranged similar to the at least one first contact element. The at least one first and / or second contact element may be provided with threads or the like, as desired, to connect the assembly to a socket, e.g. in that the assembly is screwed into the socket in a known manner to secure the assembly and to simultaneously make electrical contact between the assembly and corresponding mating electrical contacts within the socket.

The assembly may further comprise at least one translucent crest, which may be secured in the fully assembled state to the base so that it can einhausen the substrate. The dome and the base can interlock positively. The dome may be provided with a mounting structure which may include collars, stops, walls and / or side supports or the like to restrict and / or prevent movements of the substrate relative to the socket.

In the method mentioned at the beginning of the description, the solution according to the invention can be further improved with respect to the features mentioned above. One skilled in the art will have no difficulty in understanding that the implementation of each device and device feature set forth above may be interpreted as at least one advantageous method step that may be selected as desired to simplify and / or manufacture the device to provide an arrangement with the desired technical specifications.

For example, the substrate may be attached to the support member along the insertion direction in which the connection member is to be inserted into a socket. The attachment portion of the substrate may be provided with a support surface arranged substantially parallel to the insertion direction. The attachment portion may be engaged with the socket of the assembly by moving the substrate in the direction of insertion toward the socket thereby wedging and / or interlocking the substrate, socket and / or at least one contact element of the assembly with respect to each other can. Thereby, the substrate can be fastened to the base at the same time and an electrical contact between the base and the substrate can be produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Fig. 1 shows a first embodiment of an LED lamp assembly 1 according to the present invention in a schematic perspective exploded view. The assembly 1 extends along a lateral direction X, a transverse direction Y and a height direction Z, which together form a Cartesian coordinate system, that is, the lateral direction X extends perpendicular to the transverse direction Y and the vertical direction Z which is perpendicular to the transverse direction Y. In Fig. 1, the assembly 1 in an unassembled state U, in which all elements can be separated from each other and ready for assembly, is shown.

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 apart 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 in a lamp holder (not shown) are introduced. Furthermore, in the insertion direction I, the substrate 3, the first contact element 4 and the dome 6 can be brought together with the base 2, while the second contact element 5 can be brought together with the base 2 in a direction opposite to the insertion direction I.

The base 2 has a connection part 20 which is adapted to connect the arrangement 1 to an electric lamp socket, which is e.g. may be a standardized E26 socket, and with a holding part 21 for holding the substrate 3. The socket further comprises a flange 22 which surrounds the holding part 21 circumferentially 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 peripherally surrounded by a collar 24 partially circumferentially. Through an opening 24a of the collar, the holding part 21 can be accessed from below the flange 22, 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 2 to 12). The flange 22 may have an edge 22a. At least one latching element 22b may be formed on the flange 22 and in particular on the edge 22a in order to lock 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 configured so that an upper edge 25a of the holder 25 substantially with an edge 26a of the recess 26 in a plane , which extends along the lateral direction X and transverse direction Y, may be aligned, ie, they are arranged at substantially the same height. The holder 25 may have a tubular shape and may be coaxial with the recess 26, which may have a shape e.g. may be arranged with a round cross-section. The holder 25 may be provided with a plurality of holding surfaces 25b separated by corners 25c. The holding surfaces 25b and corners 25c may 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 may further be provided with a cutout 25d which opens in the insertion direction I and allows the reception of the first contact element 4 within the recess 26.

The substrate 3 may e.g. a printed circuit board, which may have a tubular shape. The substrate 3 has a fastening section 30 and a luminous section 31. On the upper side of the substrate 3, in particular the luminous section 31, a cover 32 can be arranged. The luminous portion 31, e.g. the outer periphery thereof, and / or the cover 32 may carry at least one LED. The attachment portion 30 may have a lower edge 30a and a plurality of inner attachment surfaces 30b that may be separated from one another by comers 30c in the same or a similar manner as the retention surfaces 25b of the retainer 25. The attachment surfaces 30b may be uniformly distributed along an inner circumference of the substrate 3, in particular the attachment portion 30. A notch or slot 30d may be formed in the substrate 3, in particular in the attachment portion 30. The slot 30 may extend upwardly from the lower edge 30a, e.g. in a wall portion of the substrate 3, so that a correct orientation of the substrate 3 relative to the base 2 is defined. In other words, the slot 30d may help to encode the orientation of the substrate 3 with respect to the pedestal 2, thus preventing a misconnection of the substrate 3 and pedestal 2. In addition, other attachment surfaces 30e may be disposed along an outer periphery of the substrate 3, particularly the attachment portion 30, and may also be used for attaching the substrate 3 to the base.

For making electrical contact with the LEDs mounted on the substrate 3, the substrate may be provided with contact surfaces 33 which may be arranged similar to the attachment surfaces 30b, 30e. The contact surfaces 33 may be arranged along the outer circumference of the substrate 3. In the exemplary embodiment illustrated in FIG. 1, two contact surfaces 22 assigned to the second contact element 5 may be disposed in the attachment portion 30. Further contact surfaces 34 may be provided to make electrical contact with the first contact element 4 (see FIG. 11).

The first contact element 4 may comprise an electrical contact 40, a conductor part 41 and a fitting part 42. The electrical contact 40 may be formed as a contact pin and / or contact point, which protrudes from the contact element 4 in the insertion direction I. The electrical contact 40 may be formed at an end portion of a leg 41 a of the conductor part 41. Leg 41a may be defined by a strut 41b that is substantially perpendicular to fitting portion 42, i. is substantially perpendicular to the insertion direction, extending in the insertion direction I down. The fitting part 42 of the first contact element 4 may have outer mating surfaces 43, which may be formed 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 may be formed and arranged so that they lie flush against the other 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 may be part of a second fitting part 52 with an outer fitting surface 53 and at least one inner mating surface 54 or integrated into it. The second electrical contact 50 may be e.g. be designed as a thread that meets the standard B26. The second conductor portion 51, which extends upwardly from the second electrical contact 50 opposite to the insertion direction I, may be omitted when the second electrical contact 50 is joined to the fitting portion 52, as illustrated herein. The outer mating surface 53 may be formed complementary to the inner periphery of the recess 26. The second inner mating surface 54 may be formed complementary to the outer periphery of the substrate 3 in the region of the contact surfaces 33. The second inner mating surfaces 54 may be formed and arranged so that they lie flush in the fully assembled state W on the outer periphery of the substrate 3 in the region of the contact surfaces 33.

The dome 6 may have a tubular body 50 having a lower edge portion 61 peripherally surrounding an opening 62 of the tubular body 60 which opens in the insertion direction I so as to be able to support the substrate 3 in the dome 6 take. Counter-locking means 63 can be arranged in the region of the lower edge part 61 and configured to cooperate with the latching elements 22b which are formed on the base 2 in order to fix the dome 6 to the base 2 in the fully assembled state.

Figs. 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 plan view, respectively. To achieve the fully assembled state W, a plurality of pre-assembled states V between the un-assembled state U and the fully-assembled state W may be defined. 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 top 6 are connected to each other to substantially form a stable LED lamp.

As can be seen in particular in FIGS. 2 and 3, in a lower end region of the arrangement 1, the first electrical contact 40 projects downward from the pin 23. The second contact element 5 is fixed around the collars 24 and provides the second electrical contact 50. The dome 6 is fixed to the flange 22 of the base 2, wherein the counter-locking elements 63 of the dome are engaged in the locking elements 22b on the base, so that the dome 6 is releasably secured to the base 2 again.

Fig. 6 shows the arrangement 1 in the fully assembled state W in a schematic cross-sectional view along the cross-sectional line A-A shown in Fig. 3. Here, it is apparent that the fixing part 30 of the substrate 3 in the fully assembled state W is inserted into the recess 26, so that the holder 25 engages with the fixing part 30. The holding surfaces 25b are aligned with the inner mounting surfaces 30b of the substrate 3 and abut against these. In other words, the inner mounting surfaces 30 b of the substrate 3 are flush with the retaining surfaces 25 b of the base 2. As a result, the fastening section 30, in particular the inner fastening surfaces 30b, is superposed with the retaining part 21, in particular the retaining surfaces 25b of the holder 25, in a projection along the radial direction R of the arrangement 1. In a similar manner, the inner mating surfaces 44 of the first contact element 4 rest against further contact surfaces 34 of the substrate 3.

Thus, the substrate 3 is wedged with its attachment portion between the holder 25 and the first contact element 4 and protrudes from there longitudinally upwards, without that it must be additionally held in the region 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 fully assembled state W can abut one another in at least one of several possible planes that run essentially parallel to the central axis M. The number of such planes is not particularly limited since their surface normal vectors may simply be perpendicular to the central axis M, e.g. parallel to and / or superimposed with the corresponding radial direction R.

Fig. 7 shows a detail B shown in Fig. 6. Here it becomes apparent how the dome 6 is locked in the fully assembled state W on the base. The counter-latching means 63 in the form of projections or latching projections project into the latching elements 22b, which can be formed as indentations, recesses, through-holes or the like in the edge 22a. The lower edge portion 61 of the dome 6 may be circumferentially surrounded by the edge 22 a and thus inserted into the edge 22 a on the flange in the insertion direction I, so that the dome 6 is firmly held 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. Here it is obvious that in the region 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 may protrude downwardly from the flange 22 in the insertion direction I and permit the mechanical and electrical connection of the assembly to a socket (not shown).

The first electrical contact 40 protrudes below the pin 23 in the insertion direction I. The leg 41 a extends from the first electrical contact 40 upwardly and merges with the strut 41 b, which connects the leg 41 a with the fitting part 42, which may be disposed between the inner periphery of the recess 25 and the mounting portion 30. The electrical contact 40 allows electrical connection of the assembly to a first electrical mating contact of the socket.

The fitting portion 42 may be wedged between the walls of the recess 26 and the mounting portion 30 so that the inner mating surfaces 44 flush with the substrate 3, in particular the contact surfaces 34 thereof, and the outer mating surfaces 43 flush with the inner periphery of the recess 26th issue. These are possible ways in which the holding part 21 and the fastening section 30 in the fully assembled state W can abut 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 may simply be perpendicular to the central axis M, e.g. parallel to and / or superimposed with the corresponding radial direction R.

The second contact element 5 may be in engagement with the connection part 20 of the socket such that the second fitting part 52 is inserted into the opening 24a of the collar 24. As a result, the second inner mating surfaces 54 can lie flush against the retaining surfaces 25b of the holder 25 and the contact surfaces 33 of the substrate 3. The second electrical contact 50 may be formed as a thread so as to allow a mechanical and electrical connection from the assembly 1 to a second mating contact element within the socket. Additional mechanical stability in an installation comprising the assembly 1 within a socket can be provided by the lower surface of the flange 22, which faces substantially in the insertion direction I and allows abutment of the assembly to 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 socket.

Fig. 9 is a detail D shown in Fig. 8. Here it is apparent that the shoulder 43a is formed on the outer mating surface 43 of the fitting part 42 and that a projection 26b is formed inside the recess 26. As a result, the first contact element 4 engages 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 detail E shown in Fig. 8. It will be apparent here that within the opening 24a of the collar 24, there is formed a bulge 24b projecting from a wall part of the opening 24a against the radial direction R and into the hole second fitting part 52 of the second contact element 5 engages. The second fitting part 52 is provided with a recess at an upper end portion in which a nose 53 a is formed on the outside of the second fitting part 52. The nose 53a overlaps with 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 snaps in the fully assembled state W by means of the bulge 24b and the nose 53, the ensure that the contact element 5 in one orientation superimposed on the base 2 in a projection along the insertion direction I, in the base 2, whereby a positive connection between the second contact element 5 and the base 2 is made.

Fig. 11 shows a schematic cross-sectional view of the assembly 1 in the fully assembled state W along the cross-sectional line F-F shown in Fig. 5. Here, it becomes obvious that, on the side of the first contact element 4, in particular the fitting part 42 thereof, the attachment portion 30 of the substrate 3 can be sandwiched between the holder 25 and the first contact element 4. The inner mounting surfaces 30g of the substrate 3 may be flush with the retaining surfaces 25b of the holder. The outer contact surfaces 34 can lie flush against the inner mating surfaces 44 of the contact element 4. These are possible ways in which the holding part 21 and the fixing portion 30 in the fully assembled state W can abut one another in at least one of a plurality of possible planes which extend substantially parallel to the central axis M. The number of these planes is not particularly limited since their normal surface vectors may simply be perpendicular to the central axis M, e.g. parallel to and / or superimposed with the corresponding radial direction R.

The contact element 4, in particular the fitting part 42 thereof, may be sandwiched between the attachment portion 30 and the wall of the recess 26.
