Description

Technical area

The invention relates to an LED module according to the preamble of patent claim 1, a connector for the LED module for its electrical contacting and a LED light strip with at least one LED module and a connector.

State of the art

From the LINEARLight Flex series from the company Osram GmbH, a light strip or an LED strip is known, which consists of one or more flexible LED modules. Each LED module has a ribbon-shaped flexible printed circuit board ("Flexband" or "Flexboard"), which is equipped on the upper side with light emitting diodes ("LEDs"). The LED module in turn can be composed of uniform basic elements, between which the LED module can be separated, so as to form correspondingly shorter LED modules.

The LED modules are via proprietary connectors, z. B. from the CONNECTSystem series from. Osram GmbH, mechanically and electrically connected to each other and with a power supply. These have for two LED modules to be connected to two conversion or Umkontaktiereinheiten designed electrical connector, which in turn are interconnected via a ribbon cable. Each connector is connected to one end portion of each of the LED modules. In this case, contacts of the LED module arranged at the end sections are contacted by corresponding counterparts of the connectors. Over a length of the ribbon cable, a distance between the end sections of two LED modules can be adjusted. The power supply of the LED modules is configured as a separate, packaged power supply unit, for. B. from the OPTOTORONIC series from. Osram GmbH. A length of a single contiguous light band is limited due to a drop in a supply voltage with increasing distance from a feed point.

A disadvantage of the connectors is in particular their large longitudinal extent. If the LED modules have a regular or constant pitch or "pitch" between their LEDs, this is usually exceeded in the area of the connector due to its overall length. Along the LED modules an irregular pattern of light or an uneven light distribution is created.

Such a concept is in the document DE 10 2009 021 846 A1 shown. It discloses a light strip powered at one end with a power supply module. Alternatively, the power supply module between two LED modules may be arranged as an intermediate feeder. To avoid the irregular pattern of light, the power supply module has a plurality of LEDs. This solution is designed device-consuming.

Both states of the art have the disadvantage in common that, for the axial positioning of the end section in the re-contacting unit, either one end side of the end section is brought into abutment with the re-contacting unit or the end section is clamped in the re-contacting unit. In the first case, an undesirable mechanical stress on the near the end face arranged contacts, which can lead to mechanical wear. In the second case, the positioning, for example due to a required clamping device is device-technically complex and also loads components of the LED module mechanically unfavorable to clamping.

Presentation of the invention

The object of the present invention, in contrast, is to provide an LED module which is designed such that an axial positioning in an electrical connector is less susceptible to wear. Furthermore, the object of the invention is to provide a connector for the LED module, in which an LED module is low-wear positionable. Furthermore, the object of the invention is to provide an LED light strip with at least one such LED module and at least one such connector.

Particularly advantageous embodiments can be found in the dependent claims.

The first object is achieved by an LED module having the features of claim 1, the second object by a connector having the features of claim 8 and the latter object by an LED light strip having the features of claim 18.

Advantageous developments of the invention are disclosed in the dependent claims.

An LED module has at least one semiconductor light source and extends band-shaped in a longitudinal direction. It has at least one end section arranged in the longitudinal direction, to which, in particular adjacent to an end face of the end section, at least one, preferably two, contacts for electrical contacting of the LED module are arranged. In other words, on at least one of the end sides of the module, an end portion is arranged, in which the contacts are arranged in close proximity to the end face. At the end section is Moreover, at least one contact surface is arranged on which a particular electrical connector can be supported in the longitudinal direction. According to the invention, the at least one contact surface is arranged at least in sections laterally on the LED module, in particular on a longitudinal side and / or an upper side and / or a lower side of the LED module.

Positioning of a conventional end portion is conventionally carried out in an electrical connector in the longitudinal direction either by abutting a longitudinally facing end face of the end portion with the connector or by clamping the end portion in the connector. These solutions bring the disadvantages already described with it.

In contrast, the solution according to the invention makes it possible to support the end section in or on the connector via the contact surface arranged laterally on the LED module with little outlay in terms of apparatus and with reduced mechanical stress on the end side. In addition, a supporting force acting in the longitudinal direction can be conducted past the contact or contacts, as a result of which they too can be better protected against mechanical stress.

The end section preferably has exactly two contacts, in particular for white semiconductor light sources or LEDs. In particular, for colored LEDs, it preferably has four contacts - "R", "G", "B" and "+". The LED module is preferably flexible or bendable. It preferably has two end sections according to the invention. It is further preferred that one end section has one or more further such contact surfaces.

In a preferred embodiment, the at least one contact surface is at least partially spaced from the longitudinal direction of the contact or contacts, i. the contacts are arranged closer to the front side of the module than the contact surface. With increasing distance of the contact surface of the one or more contacts are two functions of the end portion - first, the support against the connector and secondly the electrical contact - increasingly spatially separated from each other, so that the electrical or the contacts are better protected against mechanical stress.

In order to be able to position the end section particularly precisely in the longitudinal direction in or on the correspondingly formed connector, the at least one contact surface in a particularly preferred development of the invention at least partially extends approximately in the longitudinal direction, or extends approximately transversely thereto, so that an abutment shoulder over it is formed, to which a connector is applied.

In order to position the end portion in the correspondingly formed connector over the contact surface of the end portion not only in the longitudinal direction, but also in a direction transverse thereto, the at least one contact surface of the longitudinal direction in a preferred embodiment of the invention at least partially inclined at an acute angle. Thus, an investment wedge is formed on the contact surface at the end portion.

In a particularly preferred development, the contact surface is arranged on a longitudinal side of the LED module, so that a width of the end section decreases in the longitudinal direction along the contact surface. Alternatively or additionally, the contact surface is arranged on an upper and / or lower side of the LED module, so that a height of the end section decreases in the longitudinal direction along the contact surface.

In order to allow a latching of the end portion with the correspondingly formed connector and thereby a secure connection of the two, a groove extending at least in sections approximately transversely to the longitudinal direction is arranged in a particularly advantageous development at the end portion.

In an advantageous development, a cross section of the at least one end section is formed asymmetrically with respect to a symmetry surface or plane of symmetry that can be opened by a neutral fiber of the LED module. In this way, a twisting or polarity reversal is given in cooperation with a correspondingly shaped connector.

An inventive connector has a housing - particularly preferably exactly one housing - and is configured such that a first designed according to the previous description LED module with its contact surface on the connector is supported in the longitudinal direction, and that designed on him the first according to the foregoing description LED module with a second such configured LED module and / or mechanically connectable to a power supply and / or electrically contacted.

In a preferred development of the connector, a first receptacle extending into the housing into the housing is provided on the housing for the first LED module, wherein an opening of the first receptacle, into which the first LED module can be inserted, at least in sections of a contact surface of the connector is bounded. At this contact surface is the first LED module, in particular via its above-described contact surface, supported in the insertion direction. The connector thus formed builds particularly short in the insertion direction, since only the above-described end portion must dive into the receptacle until the LED module abuts. The abutment surface bordering the mouth is preferably arranged adjacent to the narrow side of the first receptacle and / or to the upper side and / or to the lower side of the first receptacle.)

In an alternative or additional refinement of the connector, at least one contact surface is formed via an inner surface section arranged laterally in the first receptacle, on which the first LED module, in particular via its above-described contact surface, can be supported in the direction of insertion. As a result, the first LED module can be accommodated beyond its end section in the connector, as a result of which a connection which is particularly secure with respect to a bending load is made possible. The bearing surface formed over this inner surface portion is preferably arranged according to the contact surface of the end portion of the LED module on a narrow side of the receptacle and / or on an upper side and / or a lower side of the receptacle.

Preferably, the contact surface of the first receptacle is at least partially spaced apart to a arranged approximately in the insertion direction bottom of the first receptacle.

In order to hold and / or contact another LED module, a second such receptacle is arranged in a preferred development of the connector on the housing. In this case, the housing is penetrated from the first receptacle toward the second of at least one, preferably of at least two, in particular of exactly two or exactly four electrical conductors. In addition, the housing may, of course, further such provided for LED modules shots, for example, three to 10, have.

In a particularly advantageous development, at least one end portion of one of the electrical conductors is angled against the insertion direction, so that a spring force can be exerted on it in particular on a contact of the LED module. Alternatively or additionally, a compression spring is disposed at least at one end portion of one of the electrical conductor approximately opposite side of the corresponding receptacle, so that the arranged at the end portion of the LED module contact via the compression spring to the end portion of the electrical conductor of the connector can be pressed , The compression spring is either electrically conductive, whereby it can contribute to the contacting of the LED module, or it is designed to be electrically insulating.

In order to enable a power supply of the one or more LED modules received by the connector, the housing of a particularly preferred development of the connector has at least one connection receptacle for connecting the power supply.

An orientation of the first recording for connection recording is arbitrary. Thus, these two recordings are arranged in a preferred development together on one side of the housing and thus have approximately in the same direction. Alternatively, the two are arranged on two mutually engaged sides of the housing or on two opposite sides of the housing. Depending on the arrangement of the power supply, which is given in most cases as a boundary condition, the correspondingly configured connector thus allows the desired course of the LED module.

In order to make the course of several recorded on the connector LED modules spatially flexible, provided for the first LED module first receptacle and provided for the second LED module second receptacle is arbitrarily oriented to each other. Thus, in a preferred refinement, the first and second receptacles are arranged on a common side of the housing or alternatively on two mutually engaged sides or on two mutually remote sides of the housing.

A functionally particularly flexible receptacle is provided if the first or second receptacle is formed integrally with the connection receptacle, in particular via a common recess of the housing. In this case, the recording is either the inclusion of an end portion of an LED module or recording a power supply.

In order to be able to contact and / or clamp a plurality of lines of the power supply independently of one another, the connection receptacle is formed in a preferred development via at least two, in particular exactly two or exactly four, connection recesses of the housing.

An LED strip light has at least a first LED module according to the preceding description and at least one connector according to the preceding description, wherein an end portion of the first LED module is inserted or inserted into a first receptacle of the connector. In this case, a contact surface of the first LED module in a direction of insertion on a contact surface of the connector can be supported or supported.

A preferred development of the LED light strip has a power supply which can be connected or connected to a connection receptacle of the connector.

Disclosed is an LED module having an end portion on which at least one electrical contact and also a side extension of the LED module, a contact surface is arranged on which a connector in the longitudinal or connecting direction can be supported.

Furthermore, a connector is disclosed, which is designed such that the LED module is supported with its contact surface on the connector in the longitudinal direction, and that via the LED module with a second such LED module and / or with a power supply mechanically connectable and / or electrically contactable.

Finally, an LED strip light having at least one such LED module and at least one such connector is disclosed.

Preferred embodiment of the invention

About the below described figures and embodiments away from constant components always have a constant reference numeral.

1 shows three embodiments of LED modules 1 ; 101 ; 201 that are only in a differently executed end section 10 ; 110 ; 210 differ. For reasons of clarity, only one end section area of the respective LED module is shown in the figures 1 ; 101 ; 201 shown. The LED module 1 has according to 1a a partially illustrated main section 2 to which a plurality of semiconductor light sources or LEDs 4 is arranged, of which in 1a only one is shown. For all disclosed LED modules 1 ; 101 ; 201 is that they are along a longitudinal direction or longitudinal axis 6 extend. They are transverse to the longitudinal direction wider than high, whereby they have a band-like shape. The LEDs 4 are at the main section 2 on an upper side or on a radiation side 8th of the LED module 1 ; 101 ; 201 arranged.

According to the 1a to 1c adjoins the main section 2 in each case the end section 10 ; 110 ; 210 , which has three electrical contacts at its front end 12 having. These are used for electrical contacting of the LED module 1 ; 101 ; 201 or the LEDs 4 , The end portion is intended to be inserted into a connector at least in sections. About the connector is the LED module shown 1 ; 101 ; 201 then, for example, with other LED modules 1 ; 101 ; 201 and / or connectable to a power supply.

According to 1a has the end section 10 a front side 14 and two equally formed laterally at the end portion 10 arranged contact surfaces 16 on. These are the longitudinal direction or the longitudinal axis 6 bent at an acute angle and form in this way an investment wedge. This investment wedge can be brought into abutment when inserted into the connector with this appropriately trained contact surfaces. Compared to conventionally designed end sections of LED modules, in which the stop is effected via an end face of the end section arranged close to the contacts, this has the advantage that the end face and the contacts are loaded less or not at all mechanically in all disclosed embodiments according to the invention.

Alternatively to the wedge-shaped end section of the LED module 1 according to 1a shows the LED module 101 according to 1b one against the main section 2 tapered end section 110 but this one is stepped and not wedge-shaped rejuvenated. From this step-shaped taper results that one laterally at the end portion 110 arranged contact surface 116 in the longitudinal direction of the LED module 101 So from the main section 2 towards a front side 114 of the end section 110 , points. The contact surface 116 is on both sides of the longitudinal axis 6 arranged. Analogous to the first embodiment according to 1a is the contact surface 116 can be brought into abutment with a corresponding contact surface formed on a connector. The less deeply the contact surface of the connector is arranged in the connector, the less deep the LED module 101 be inserted into the connector. Further explanations will be given on the basis of 6 ,

Also, the third embodiment of the LED module 201 according to 1c like the first two embodiments has the main section 2 , on the emission side 8th the LEDs 4 are arranged. Likewise, it extends along the longitudinal axis or longitudinal direction 6 ribbon-shaped. It also shows the three contacts 12 on.

An end section 210 this third embodiment is basically similar to the end portion 110 according to 1b , however, points in the area of the contact surface 116 on both sides of the longitudinal axis 6 one groove each 218 on, extending across the longitudinal axis 6 in the end section 210 extends into it. In this way, a width of the end portion is reduced or tapered in this area. The grooves 218 have the purpose of allowing a latching with a correspondingly formed connector or arranged on this latching device. In this way, the LED module 201 safe against displacement in the longitudinal direction 6 be determined and a pull-out force is increased.

2 shows a first embodiment of a connector according to the invention 20 in a front or front view. A housing 22 of the connector 20 extends, starting from an in 2 shown end face, in the viewing plane along a direction of insertion into it. In the front side 24 is an estuary 26 one in the direction of insertion into the housing 22 extending first shot 28 educated. In the first shot 28 is for example the LED module 1 ; 101 ; 201 according to the 1 insertable. Furthermore, the connector 20 a connection recording 30 on, over four arranged in series on the front Auschlussausnehmungen 32 is formed. The connection recording 30 , or their Anschlußausnehmungen 32 are for connecting a power supply or a power cable, in particular of the individual power lines, provided. The connector 20 is with respect to one to the front 24 formed symmetrically parallel plane so that it is not shown, behind the viewing plane according to 2 arranged, second receptacle for receiving and contacting a further LED module. Likewise, the connector 20 because of this symmetry another, not shown for the same reason connection receptacle.

3 shows a guided in the insertion direction section section AA, as in accordance with 2 is defined. Here is one of the connection recesses 32 and the first shot 28 shown cut. In the first shot 28 is for contacting the contacts 12 of the LED module 1 ; 101 ; 201 (see 1a - 1c ) an electrical conductor 34 provided in 3 only shown in sections. This has one to the front 24 pointing contact section 36 , The contact section 36 is doing towards a central axis or mid-plane 38 of the connector 20 , or angled against the insertion direction. About the angled end section 36 In this way, on the one hand, the contact 12 of the LED module 1 ; 101 ; 201 (see. 1a - 1c ) and on the other hand a spring force approximately normal to the contact 12 of the LED module 1 ; 101 ; 201 be exercised so that the LED module 1 ; 101 ; 201 in the first shot 28 is determinable. The electrical conductor 34 with its end section 36 thus fulfills a dual function of contacting and fixing.

A similar electrical conductor 40 with an angled against the insertion direction contact portion 42 is in each of the final exits 32 arranged. He also can electrically contact an electrical line of the power supply and also set mechanically on the prescribed clamping effect or spring action. The insertion direction is in 3 on the front side 24 symbolizing assigning arrows.

4 shows a second embodiment of a connector 120 in a guided in the insertion direction partial section. The area shown therein corresponds to an outbreak A, as in section AA according to 3 indicated on the bottom right. The connector 120 is different from the connector 20 according to 2 and 3 only in the design of the contact, as for the LED module 1 ; 101 ; 201 according to 1 in the first shot 28 is provided. Also in the embodiment according to 4 the contacting takes place via an electrical conductor 140 However, unlike the embodiment according to 2 and 3 not angled. The electrical conductor 140 is instead plate-shaped and on one side of the first receptacle 28 arranged.

For a necessary contact force, with the in the insertion direction in the first recording 28 introduced LED module 1 ; 101 ; 201 or its contacts 12 (see. 1 ) on the plate-shaped electrical conductor 140 is pressable, is in the first shot 28 a compression spring 44 intended. The compression spring 44 has a parallel to the insertion direction arranged first leg 46 and an angled second leg 48 on. This is so strong from the first leg 46 angled so that it points in the direction of insertion substantially. Since the material of the compression spring 44 is elastic, can over the second leg 48 in the inserted state of the LED module 1 ; 101 ; 201 a normal force on one of the contacts 12 of the LED module 1 ; 101 ; 201 opposite bottom of the LED module 1 ; 101 ; 201 be imprinted. This is how the LED module becomes 1 ; 101 ; 201 on the electrical conductor 140 pressed. In addition, there is another effect of the compression spring 44 which consists in that due to the running in the insertion direction bending of the second leg 48 an unintentional release of the LED module from the first recording 28 is prevented. This is due to the fact that one of the normal force of the compression spring 44 resulting friction force the second leg 48 in the case of a pull-out movement of the LED module against the first leg 46 spreads. With increasing spreading it takes on the second leg 48 on the bottom of the LED module acting normal force, so that a clamping effect is increased. The second leg 48 canted into the side of the LED module facing it. In this way, the LED module is protected on device-technical simple manner against accidental release of the electrical contact or the mechanical connection with the connector.

The compression spring takes over in the illustrated embodiment, only the holding function. Alternatively or additionally, it is designed such that the LED module is electrically contactable via it.

5 shows a third embodiment of a connector 220 with a first shot 228 , which are integral with a connection receptacle 230 , or with their Anschlußausnehmungen 232 , is trained. Integrity is to be understood in the sense that the Anschlußausnehmungen 232 and the first shot 228 not separated, but from a common, contiguous, in a housing 222 formed recess are formed. This recess opens into an end face 224 of the connector 220 , Analogous to the embodiments of the connector according to the 2 to 4 also shows the third embodiment according to 5 four connection recesses 232 and thus four electrical conductors for contacting (not shown). The connection recesses 232 are doing on a broadside of the first shot 228 arranged evenly distributed. About the connector thus formed 220 can thus on the first recording 228 either either an LED module with a maximum of four contacts or a cable with a maximum of four contacts are electrically contacted and mechanically connected.

The embodiments of the connector 20 and 120 according to the 2 . 3 and 4 On the other hand, they are functionally more flexible since they can be connected to an LED module or a power supply or a cable or both. A great advantage of these two embodiments is that a center feed can be realized via them. The center feed is characterized in that two LED modules are connected to one another via the connector and, on the other hand, current is supplied to this connection point. In this way, long lengths of lightbands are possible which have a plurality of LED modules connected in series via connectors. Their power supply takes place for example at an end portion of the light strip and, in order to obtain the most uniform light intensity along the light strip, also at least one center feed using one of the connectors according to the 2 to 4 ,

A first embodiment of an LED light strip 350 shows 6 , The LED light strip 350 is not complete, but only in a section around a connector 320 presented around. The connector 320 represents a fourth embodiment of a connector according to the invention. The connector 320 has a first face 324 and a second, facing in an opposite direction end face 325 , From the first front 324 in the insertion direction in the connector 320 into it extends a first shot 328 and from the second end 325 in the opposite direction of insertion extends into the connector 320 a second shot 329 into it. In the first shot 328 is a first LED module 101 , as in the embodiment according to 1b shown is inserted. Another such LED module 101 is accordingly in the second recording 329 of the connector 320 inserted. It is easy to see that there is a distance or pitch d, as between two LEDs 4 the respective LED modules 101 is formed, even over the connector 320 is constant. At the in 6 shown relatively small pitch d, this is made possible by the fact that the connector 320 has a very short length compared to the prior art.

In 6 It is also easy to see that the connector 320 compared with the prior art, in which, as described above, a first Umkontaktierer is connected via a connected ribbon with a second Umkontaktierer, is designed to be very compact and space-saving due to its einstäusigen design.

In 6 are in the connector 320 arranged components or components shown schematically by dashed lines. Good to see are the respective end sections 110 the LED modules 101 that in the respective shots 328 . 329 are arranged. Furthermore to recognize their contacts 12 that have electrical conductors 34 (see. 3 ) of the connector 320 are electrically connected to each other. At this point it should be noted that the connector 320 from the connector 20 according to the 2 and 3 only different in the number of contacts.

Furthermore, in 6 good to recognize that over the front ends 324 . 325 each a contact surface of the connector 320 is formed, at the the contact surface 116 the LED modules 101 is brought into attack. Thus, not the main section penetrates 2 but only the end section 110 in the connector 320 one.

Due to the side of the LED module 101 arranged contact surface 116 is it possible for the connector 320 in the longitudinal direction of the LED module 101 or the LED light strip 350 considered very slim builds.

7 shows a second embodiment of an LED light strip 450 , which differs from the LED strip according to 6 only in a fifth embodiment of a connector 420 different. The through the connector 420 connected LED modules 101 are identical to those according to 6 and according to 1b ,

Also the connector 420 has three electrical conductors 34 on, over which the two LED modules 101 are electrically connected to each other. Reference numerals for the contacts are omitted for reasons of clarity.

The connector 420 also has a T-shape deviating from all previous embodiments. A crossbeam of the T is about one between the two end faces 324 and 325 arranged housing part, a longitudinal beam of the T via a for receiving a power supply 452 provided housing part formed. The latter housing part is approximately at right angles to the end sections 110 angled receiving housing part. The illustrated power supply 452 in this case represents a center feed, as already mentioned, is the center feed takes place laterally on the LED light strip, whereby a radiation of the LEDs 4 not disturbed.

For clarity, in 7 on a representation of in the connector 420 arranged contacting the power supply 452 waived.

Unlike when in 6 illustrated embodiment, the connector 420 internal contact surfaces 424 and 425 on where the contact surfaces 116 the LED modules 101 supported in the insertion direction. These contact surfaces 424 . 425 are on an inner surface portion of the corresponding receptacle 328 . 329 arranged. That's why the LED modules are 101 additionally in sections with its main section 2 in the appropriate recording 328 . 329 pushed in, causing the connector 420 compared with the connector 320 according to 6 comparatively wide and slightly longer builds.

A sixth embodiment of a connector 520 is in 7 Shown schematically on the top right. An illustration of connected LED modules or power supply was omitted. What is striking about this exemplary embodiment is that it deviates from the T-shape shown on the left in the figure. This is to express that the connector can have receptacles for LED modules or power supply lines arranged at any desired angle relative to one another. In this case, a number of recordings is not limited and may exceed the number of three shown so far and be four or five, for example.

In summary, the design of the end section of the LED modules according to the invention, in cooperation with the connector designed according to the invention, makes possible a very flexible design of LED light strips. The gain in flexibility over the prior art results in particular from the smaller space required for the connector. Furthermore, the arbitrary arrangement of the various receptacles for the power supply and / or the LED modules on the connector allows a great deal of freedom in the spatial laying of LED light strips.

All embodiments have in common that an LED module is very easily inserted into a receptacle, whereby a mounting is simplified. In order to provide a safety catch of the LED module from the recording no other components are also necessary if provided via the electrical conductor and / or via the compression spring, a mechanical clamping connection or via the groove, a mechanical locking.

Disclosed is an LED module having an end portion on which at least one electrical contact and also a side extension of the LED module, a contact surface is arranged on which a connector in the longitudinal or connecting direction can be supported.

Furthermore, a connector is disclosed, which is designed such that the LED module with its Contact surface on the connector can be supported in the longitudinal direction, and that the LED module is mechanically connected via a second such LED module and / or with a power supply and / or electrically contacted via it.

Finally, an LED strip light having at least one such LED module and at least one such connector is disclosed.
