Description

[0001] The invention relates to a connection element for the electrical connection of an LED light source, wherein the LED light source has a circuit board which is provided with the contact springs for the electrical supply of the LED, with an annular frame which is intended to overlap a circuit board and to hold it mechanically on an arrangement surface of a counter bearing, with a contact arrangement which is mounted in the frame and serves to supply the LED with electricity, wherein the frame is divided into an outer ring and an inner ring and the outer ring is intended to surround the circuit board and to hold it in a parallel direction to the arrangement surface of the counter bearing and the inner ring overlaps the circuit board at least in some areas and is intended to hold the circuit board in a vertical direction to the surface of the counter bearing.

[0002] The invention also relates to a light-directing component for a luminaire, comprising a component base body which defines a component space, wherein the component base body has a base part which forms an opening for receiving a light source.

[0003] Connection elements are well known in the prior art, for example from EP 2 083 489 A1 by the applicant. They consist of a ring element which overlaps a printed circuit board and is able to hold the printed circuit board between itself and a counter-bearing, in particular a heat sink. For this purpose, the ring element is fastened to the counter-bearing by means of screw bolts, for example. It sits on the circuit board with part of its surface facing the circuit board. The ring element carries contacts in contact chambers. These contacts have a clamping section into which the stripped end of a connecting conductor is to be inserted. The connecting conductor is thus held in the clamping section and electrically contacted. Each contact then has spring legs which serve as a pressure contact and rest on contact pads on the circuit board.The connection element from the aforementioned patent serves both to make electrical contact and to mechanically secure the circuit board to a counter-bearing. The circuit board itself carries an LED. It thus represents a light source used in lighting fixtures instead of more common incandescent lamps or similar conventional light sources.

[0004] Generic connecting elements have proven extremely effective in practice and are used particularly in spotlights that use LED lamps.

[0005] LED technology has evolved significantly in the meantime. Printed circuit boards with mounted LEDs are now available in a wide range of brightness levels and power levels, which is why the shape and, above all, the size of the printed circuit boards and the LEDs arranged on them vary considerably from manufacturer to manufacturer and across different power classes.

[0006] Therefore, a wide variety of connection elements can be found on the market, each of which makes many specific LED circuit boards from a particular manufacturer and with a specific power class usable. This is fundamentally advantageous, as suitable connection elements are available for every application. However, this range does not meet the requirements of the lighting industry. There, subcomponents of luminaires are kept pre-assembled and then finally assembled upon acceptance of a specific luminaire type.

[0007] For example, a specific luminaire type is offered in various wattages, i.e., with different luminous intensity or color temperature of the light source. For this type of luminaire, the standardized housing components are kept in stock. Furthermore, the actual lighting device—usually consisting of an LED light source mounted on a suitably dimensioned heat sink—is kept in stock in various versions. This allows for a modular system to be used when an incoming luminaire order is received, allowing for easy final assembly of the requested luminaire.

[0008] However, the disadvantage here is the need to stock a large number of lighting units. The fully pre-assembled unit, consisting of the LED bulb, connector element, and suitable heat sink, represents a significant value for the actual luminaire. Depending on the variety of a luminaire type, a large inventory is required.

[0009] Subsequently, according to DE 20 2023 105 716 U1 of the applicant, a generic connecting element was developed which compensates for existing disadvantages by the two-part frame of the connecting element into outer ring and inner ring.

[0010] However, the connection elements are also increasingly subject to the requirement of quick interchangeability, sustainability, and safety. Furthermore, simplified handling and a progressive reduction in component count are becoming increasingly important in the lighting industry, but the light quality of the lamps used must not be compromised. Optimizing the emitted light quality is even desired and required.

[0011] At the same time, the requirements for generic light-directing components are also increasing. These can include optics, reflectors, lenses, or even collimators. On the one hand, these should ensure the best possible light emission and thus light efficiency. On the other hand, the concept of interchangeability and sustainability is increasingly becoming a focus for light-directing components, under the premise of safety and ease of handling.

[0012] The object of the invention is therefore, on the one hand, to create a connection element based on the last-mentioned prior art which, in addition to optimized handling, is still subject to the required safety criteria and ensures a reduction in components under the premise of high-quality light quality.

[0013] The object is achieved by a connection element according to claim 1, in particular by the characterizing part, according to which the inner ring is implemented in a light-directing component.

[0014] The invention now provides that the inner ring and the light-directing component are no longer two separate components, but rather the inner ring is part of the light-directing component. This ensures a reduction in the number of components, while also allowing the manufacturer to pre-assemble the connecting element and the light-directing component. The arrangement of the inner ring with the light-directing component on the outer ring can be performed at the final assembly position. Furthermore, the reduction in the number of components also results in a reduction in time, since fewer components now need to be arranged next to one another.

[0015] For this purpose, the inner ring forms the base part of the light-directing component, with the inner ring implemented in the light-directing component being positioned downstream of the outer ring in the light exit direction. The inner ring is thus mounted on the outer ring in such a way that the inner ring can be inserted vertically into the outer ring for fastening to the outer ring, opposite to the light exit direction. For this purpose, the inner ring, and thus the light-directing component, is arranged in the outer ring.

[0016] It is envisaged that the inner ring forms at least one fastening element, which cooperates with a fastening element of the outer ring for fastening. This cooperation serves to firmly, yet potentially detachably, arrange the components of the connecting element together, thus positioning the connecting element functionally and securely in the final assembly position.

[0017] Furthermore, mounting the light-directing component in close proximity to the circuit board with the LED ensures that the emitted light from the LED, or rather the light rays, shine directly into the light-directing component, which then transmits the light rays. The light emitted from the light-directing component thus exhibits high light quality and intensity, as there is virtually no light beam loss. Overall, the light efficiency of the light source is thus significantly improved.

[0018] It is further provided that the inner ring forms a stop means as a fastening element and the outer ring forms a stop means recess as a fastening element.

[0019] The advantage here is that the sling can be inserted into the sling recess to position the inner ring within the outer ring. By twisting the inner ring, the inner and outer rings can be secured together in a bayonet-type manner. Bayonet connections are particularly stable connections that withstand mechanical stress, especially vibrations.

[0020] It is also envisaged that the fastening element of the inner ring and the fastening element of the outer ring are screw fasteners. The advantage of this type of fastening element is that it is detachable. The inner ring, which forms the screw fastener, is arranged on the outer ring and then moved against the light exit direction, thus screwing it against the outer ring. The force applied fastens the outer ring and the inner ring with the light-directing component to one another. The inner ring with the screw fastener can be released by unscrewing the inner ring with the light-directing component in the light exit direction. An advantage is that both the fastening and the removal of the inner ring with the screw fastener is possible without tools. Furthermore, the loosening of the screw fastener is reversible.This means that even after the initial arrangement and subsequent loosening of the inner ring with screwing means, further fastening processes are possible.

[0021] The inner ring is designed to have an outer contour formed as an external thread, and the outer ring to have an inner contour formed as an internal thread, with the external thread of the inner ring interacting with the internal thread of the outer ring for fastening within the outer ring. Through the interaction of the internal thread of the inner ring with the external thread of the outer ring, the inner ring with the light-directing component and the outer ring are fastened to one another by means of self-locking frictional engagement, i.e., force-locking. This fastening method is very stable, as loosening is only possible by moving the two threads apart. This fastening method is therefore reliably protected even against strong mechanical loads, especially vibrations.

[0022] It is also possible for the inner ring to have an inner contour formed as an internal thread and for the outer ring to have an outer contour formed as an external thread, wherein the external thread of the inner ring cooperates with the internal thread of the outer ring for fastening in the outer ring.

[0023] Alternatively, it is envisaged that the fastening element of the inner ring and the fastening element of the outer ring are locking means that interact with each other.

[0024] The fastening element of the inner ring forms a spring receiving space for a detent spring, which extends with respect to the outer ring resting on the arrangement surface into an area below the arrangement surface, wherein the outer ring as a fastening element forms a dome for receiving the detent springs.

[0025] In order to compensate for high tolerances regarding the thickness of the circuit board and, if applicable, the thermal interface arranged between the circuit board and the counter bearing, the inner ring must be able to perform a comparatively large movement stroke vertically relative to the mounting surface of the counter bearing or in the direction of the LED's light emission. At the same time, the detent spring must be able to exert sufficient contact pressure in the direction of the mounting surface in every position of the inner ring caused by the tolerances.

[0026] This requires a detent spring that can cover a comparatively large spring travel and exert sufficient contact force. Space must be created in the connecting element to accommodate a large spring travel. High spring forces require specific dimensions of the detent spring element. These requirements for a detent spring contradict the technical need to create connecting elements that are as flat as possible to avoid shadowing of the emerging light by the connecting element.

[0027] The invention provides for the required installation space for the detent spring to be used to a region below the arrangement plane of the counter bearing, or at least to be drawn into this area. In this way, the thickness of the connecting element, measured in the light exit direction or vertically to the arrangement plane of the counter bearing, can be reduced to the absolute minimum. Shading of the emerging light by the connecting element is reliably avoided or greatly reduced. Nevertheless, sufficient installation space is provided for a detent spring element, which requires a sufficiently large spring accommodation space due to the spring forces to be applied and, in particular, the required spring travel.

[0028] It is envisaged that the spring receiving space is formed by a dome that originates from the underside of the outer ring and is directed, in particular, opposite the light exit direction. The spring element can be arranged in this dome and thus obtains sufficient movement space for the required spring travel, particularly in the case of a spring element shown in the exemplary embodiment with a pivot axis aligned parallel to the mounting surface.

[0029] Anderseis, the object of the invention is to create a light-directing component which ensures the most light-efficient radiation of the illuminants, also guarantees safe and easy handling and is conducive to interchangeability and sustainability.

[0030] The object is also achieved by a reflector according to claim 11, in particular its characterizing part, according to which the bottom part of the light-directing component is designed as an inner ring of the connecting element according to one of claims 1 to 10.

[0031] The invention will now be explained in more detail using six exemplary embodiments, which reveal further advantages and features. They show: Figure 1: first embodiment of the first connection element with light-directing component in exploded view, Figure 2: perspective view of the first connection element with light-directing component r according to Figure 1 , Figure 3: Top view of the first connection element with light-directing component according to Figure 2 , Figure 4A: Exploded view of the sectional view of the first connecting element with reflector according to section lines IIIA - IIIA from Figure 3 , Figure 4B:Sectional view of the first connecting element with light-directing component according to section lines IIIA - IIIA from Figure 3 , Figure 5: second embodiment of the second connection element with light-directing component in exploded view, Figure 6: perspective view of the second connection element with light-directing component in the assembled state according to Figure 5 , Figure 7: Top view of the second connection element with light-directing component in assembled state according to Figure 6 , Figure 8A: Exploded view in section of the second connecting element with light-directing component in assembled state according to section lines VIIB - VIIB from Figure 7 , Figure 8B: Sectional view of the second connecting element with light-directing component in assembled state according to section lines VIIB - VIIB from Figure 7 , Figure 9:third embodiment of the third connection element with light-directing component in exploded view, Figure 10: fourth embodiment of the fourth connection element with light-directing component, Figure 11: fifth embodiment of the fifth connection element with light-directing component, Figure 12: sixth embodiment of the sixth connection element.

[0032] In the Figures 1 to 4B A first embodiment of the invention is designated overall by reference numeral 100. A second embodiment of the invention is shown in the Figures 5 to 8B shown and identified overall by reference number 200. The Figure 9 shows the third embodiment as a whole with the reference number 300. In the Figure 10 The fourth embodiment of the invention is shown with the reference number 400. A fifth embodiment 600 is shown in the Figure 11 Ultimately, the Figure 12 a sixth embodiment 700.

[0033] The embodiments 100 / 200 / 300 / 400 / 600 / 700 of the invention have a number of identical components. Where identical or functionally identical components are used, they are named the same and differ only in that they use either the number range 100, the number range 200, the number range 300, the number range 400, the number range 600, or the number range 700.

[0034] Thus, what was said about the first embodiment always applies to the second to sixth embodiments as long as the same or similarly functioning components are concerned.

[0035] In all figures, the installation direction E is defined as perpendicular to the arrangement plane 510 on the surface 511 of a heat sink 500, and the light exit direction R is defined as perpendicular away from the arrangement plane 510. The arrangement plane 510 is shown as the surface 511 of a heat sink 500, on which all embodiments of the invention can be mounted.

[0036] For all figures it also applies that in the light exit direction R a system axis X runs through the center M of the arrangement of outer and inner rings.

[0037] The Figures 1 to 4 show the first embodiment 100 of the first connection element 110 with a light-directing component 105, which is designed as a reflector 111.

[0038] In the Figure 1The connecting element 110 and the reflector 111 are shown in an exploded view. The connecting element 110 has an outer ring 112. The outer ring 112 interacts, on the one hand, with a circuit board 114, which carries an LED 115 as a light source and contact springs K for contacting. On the other hand, the connecting element 110 cooperates with a counterbearing, for example, a heat sink (not shown). Instead of the heat sink, however, the counterbearing can also represent a lighting component of any type.

[0039] The connection element 110 is attached to the heat sink by means of two screws 117, which form a screw head 118 and a screw body 119. The connection element 110 holds the LED 115 of the circuit board 114 between itself and the heat sink.

[0040] The outer ring 112 initially has a base plate 120. The base plate 120, in turn, forms an opening 121. This opening 121 defines the inner silhouette 122 of the outer ring 112, which is divided into a rectangular, in particular square, insertion contour 123 and an engagement contour 124. The engagement contours 124 merge into the insertion contour 123.

[0041] On the base plate 120, there is an annular collar 125, which surrounds the opening 121 and has receiving holes 126. The receiving holes 126 serve to accommodate the screw 117.

[0042] The ring collar 125 forms inner wall sections 125, which are interrupted by fastening elements 136 designed as lifting device receptacles 128, which run on a common radius around a center point M. The lifting device receptacles 128 form blind hole sections 129 mounted parallel to the base plate 120.

[0043] The contact arrangement provided for the electricity supply of the circuit board 114 is not shown in the exemplary embodiments, since it plays only a minor role for the core of the invention.

[0044] The reflector 111 has a reflector base body 130, which in turn defines a reflector chamber 131. The reflector base body 130 has a base part 132 with an opening 133 for receiving the LEDs 115, wherein the base part 132 simultaneously serves as the first inner ring 132A of the connection element 110. The inner ring 132A has, on the one hand, a bottom U, which faces the outer ring 112, and also has, on its outer circumference, two diametrically opposed fastening elements 134, which are designed as stop means 135.

[0045] The Figures 2 to 4 show the assembled state of the connecting element 110 with reflector 111. The Figure 3It can be seen that the opening 133 is arranged above the circuit board 114 with LED 115 located in the outer ring 112 and the reflector 111 does not cover the circuit board 114.

[0046] The Figure 3 shows the top view of the connection element 110 assembled with the reflector 111. It can be clearly seen that the opening 133 of the reflector 111 surrounds the LEDs 115 and that the inner ring 132A rests directly on the circuit board 114 (not shown) and the light rays of the LED 115 shine directly into the reflector space 131 and are not deflected by other components.

[0047] The Figure 4A shows the outer ring 112, as well as the reflector 111 with the inner ring 132A. The arrangement of the blind hole sections 129 in the inner wall sections 125 of the outer ring 112 is clearly visible. These serve to accommodate the stop means 135.

[0048] In the Figure 4BIn the assembled state of the connecting element 110 with reflector 111, it can now be clearly seen that the stop means 135 of the inner ring 132A lie in the blind hole sections 129 of the outer ring 112 and arrange the reflector 111 on the outer ring 112.

[0049] The mechanism of action of the connecting element 110 with the reflector 111 is explained below.

[0050] First, the outer ring 112 is screwed onto the heat sink (not shown) by means of the screws 117 engaging the receiving holes 126. The printed circuit board 114 with the LEDs 115 is then loosely inserted into the insertion contour 123. Within the outer ring 112, the printed circuit board 114 is now securely held against horizontal displacement or displacement parallel to the assembly surface.

[0051] The reflector 111 is then fastened in the outer ring 112 with the base part 132 designed as an inner ring 132A.

[0052] For this purpose, the stop means 135 of the inner ring 132A are inserted into the stop means receptacles 128 of the outer ring 112 and then moved into the blind hole sections 129 in a bayonet-type manner. This secures the inner ring 132A with the reflector 111 to the outer ring 112. The bayonet lock is a particularly stable fastening method that withstands mechanical loads in particular. The force exerted by the stop means 136 is transferred to the outer ring 112 and the circuit board 115, so that they are secured due to the pressure force of the inner ring 132A. The circuit board 114 can no longer fall out of the insertion contour 123.

[0053] Since the contact bridge (not shown) is seated on the inner ring 132A, the circuit board 114 is contacted when the inner ring 132A is fully arranged and is thus functional.

[0054] It is particularly advantageous that the reflector 111 is now arranged particularly close to the circuit board 114 and the LEDs 115. This allows the light emitted by the LEDs 115 to radiate directly into the reflector base body 130 and from there exit the reflector 111 in the light exit direction R.

[0055] This ensures that the light efficiency is particularly high, since the light rays are not unnecessarily deflected by the outer ring 112, but radiate directly into the reflector base body 130.

[0056] In the Figures 5 to 8B a second embodiment 200 of the connection element 210 and reflector 211 according to the invention is shown.

[0057] The connecting element 210 has an outer ring 212. The outer ring 212 has an upper side S and a lower side T. From the underside of the outer ring 212, fastening elements 235, designed as domes 240, emerge. A receiving space 241 of the dome 240 allows the inner ring 232A to be inserted into the outer ring 212.

[0058] A detent spring 244 is located in the receiving space 241 of the dome 240. These initially comprise a spring leg 245, which a detent leg 246 serves to anchor in the outer ring 212, particularly within its dome 240. In the specific embodiment, the detent leg 246 is directed radially outward and toward the upper side of the connecting element 210 facing away from the counter bearing. However, this is not absolutely necessary for the function of the detent leg 246. In the exemplary embodiment, the detent leg 246 also originates from the lower end of the spring leg 245 facing the heat sink.

[0059] At its end facing the top of the connecting element 210, the spring leg 245 carries a locking contour, designated overall by the reference number 247, which is directed radially inward toward the inner ring 232A. Starting from a locking contour apex 248, which also defines the maximum radial inner position of the locking contour 247, a retaining leg 249 slopes diagonally toward the heat sink and terminates in the spring leg 245. Toward the top of the connecting element 210, starting from the locking contour apex 248, a spreading leg 250 extends radially outward and forms, as it were, the free, upper end of the locking spring 244.

[0060] The inner ring 232A has two fastening elements 234 on its outer circumference, which are designed as a spring receiving space 242. The spring receiving space 242 each has a spring support leg 243. Each spring support leg 243 forms a locking lug 251 which points radially outwards with respect to the light exit direction R. Each locking lug 251 has a locking surface 252 pointing towards the upper side remote from the counter bearing and a spreading surface 253 pointing towards the counter bearing. Starting from a locking lug apex 254, which simultaneously defines the maximum radial extension of the locking lug 251 outwards, the locking surface 252 rises as an inclined surface in the direction of a vertical axis V. The spreading surface 253, on the other hand, is designed as an inclined surface on the spring support leg 243 which falls in the direction of the vertical axis V.

[0061] The Figure 8A and 8B also allow a detailed view into the dome 240 of the outer ring 212.

[0062] First, the dome 240 has an insertion opening 255 toward the top of the connecting element 210, which allows access to a dome interior 256. The dome interior 256 can be divided into various functional areas, as described below.

[0063] First, the dome interior 256 provides a spring support leg receptacle 257, into which the spring support leg 243 is inserted when the connecting element 210 is assembled. The spring support leg receptacle 257 is arranged radially inwardly in the dome interior 256.

[0064] A locking leg receptacle 258 is provided radially outwardly in the dome interior 256. This also forms a locking leg seat 259. The free end of the locking leg 246 is supported on this locking leg seat 259 for anchoring the locking spring 244 in the dome 240. The arrangement of the locking leg 259 in the locking leg receptacle 258, including the anchoring of the locking leg 246 in the locking leg seat 258, is Figure 8B visible.

[0065] A spring leg shaft 260 is formed in the dome 240 between the spring support leg receptacle 257 and the locking leg receptacle 258. The spring leg shaft 260 is delimited by a support wall 261 relative to the spring support leg receptacle 257, which prevents excessive radial inward displacement of the spring leg 245 toward the spring support leg 243. In the direction of the locking leg receptacle 258, the spring leg shaft 260 is delimited by a guide pin 262, which holds the lower end of the spring leg 245 in a stable position in the spring leg shaft 260 and prevents the spring leg 245 from jumping into the locking leg receptacle 258.

[0066] The support wall 261 as well as the guide pin 262 are directed parallel to the vertical axis V, so that the functional spaces, namely the spring support leg receptacle 257, the locking leg receptacle 258 and the spring leg shaft 260 are vertically separated from one another and accessible via the insertion opening 255 of the dome 240.

[0067] The following is the assembled state of the outer ring 212 with the inner ring 232A based on the Figure 8 described.

[0068] First, the detent springs 244 are inserted into the respective associated dome 240 opposite to the light exit direction R, i.e., from the top side of the connecting element 210. In doing so, the spring legs 245 enter the spring leg shaft 260. At the same time, the detent leg 246 finds its hold in the detent leg seat 259 of the detent leg receptacle 258. In this way, the detent spring 244 locks into the dome 240. The detent contour 247 of the detent spring 244 extends radially inward in the direction of the vertical axis V into the spring support leg receptacle 257.

[0069] The outer ring 212 is now placed on the heat sink, with the domes 240 being inserted into the cavities of the heat sink (not shown). In this way, the underside of the outer ring 212 facing the heat sink rests on the mounting surface of the heat sink.

[0070] To assemble the connection element 210, the circuit board 214, i.e., the LED lamp 215, is now inserted into the insertion contour 223 formed by the outer ring 212, so that the underside of the circuit board 214 also rests on the mounting surface of the heat sink. If necessary, thermal conductivity (not shown) is also present between the circuit board 214 and the heat sink.

[0071] Within the outer ring 212, the circuit board 214 is now securely held against horizontal displacement or displacement parallel to the arrangement surface.

[0072] The inner ring 232A with the reflector 211 is now placed onto the outer ring 212 opposite the light exit direction R. The spring support legs 243 are inserted into the respective dome 240 and then into the corresponding spring support leg receptacle 260. The spreading surfaces 253 of the respective locking lug 251 come into contact with the respective spreading leg 250 of the locking spring 244, whereby the resulting inclined surface pairing 253 / 250 leads to a radially outward displacement of the locking contour 247. This movement reaches its maximum when the locking contour vertex 248 is positioned on the locking lug vertex 254.

[0073] Subsequently, as the insertion movement continues counter to the light exit direction R, the retaining legs 249 engage with the respective locking surface 252 of the locking lug 251. The locking contour 247 is thereby displaced radially inward in a spring-return elastic manner, with the inclined surface pairing between the retaining leg 249 and the locking surface 252 applying a force component directed toward the arrangement surface to the inner ring 232A. As a result, the inner ring 232A with the reflector 211 is clamped against the inserted circuit board 214 and ensures sufficient contact pressure of the circuit board 214 on the heat sink to promote optimal heat dissipation. In the same way, the aforementioned force component, which clamps the inner ring 232A toward the arrangement surface, also promotes correct contact of the contact arrangement with the contact fields of the circuit board 214 in order to achieve correct electrical transition values (not shown).

[0074] Due to the dome 240 extending into an area below the arrangement surface, a sufficiently large space is created to create a spring element in the form of the detent spring 244 which is elongated in the light exit direction R or parallel to the vertical axis V and which, over its longitudinal extension of the spring leg 245 within the spring leg shaft 256, offers sufficiently large spring travel for holding the inner ring 232A in the outer ring 212.

[0075] A particularly advantageous feature of this configuration is that the reflector 211 is now arranged directly with the inner ring 232A on the circuit board 214 and the LEDs 215. This allows the light emitted by the LEDs 215 to radiate directly into the reflector base body 230 and from there exit the reflector 111 in the light exit direction R. The light rays are not deflected by the outer ring 232, as is otherwise the case in the prior art. This ensures particularly high light efficiency.

[0076] As an alternative to the reflectors 111 and 211, the light-directing component 305, 605 can be designed as a collimator 370, 670, also collimator lens, as shown in the Figure 9 and 11 shown. Furthermore, the light-directing component 405, 705 can also be designed as a holding frame 430, 730 for a collimator 473, 773. The respective contact bridges (not shown) are seated in the holding frame 430, 730.

[0077] In the Figure 9 and 11 The inner ring 332A, 632A is formed as the base part 332, 632 of the collimator 370, 670.
