For this purpose, the lamp may have at least one suspension element, for example in the form of at least one pendulum or at least one cable 25.

In the example shown, the lamp as a whole is elongate, so that it extends along a longitudinal axis L. FIG. 2 shows the luminaire in a side view and FIG. 3 shows an end view or frontal view, ie in a viewing direction parallel to the longitudinal axis L.

The luminaire has a carrier element 2, which comprises an elongate, U-shaped receiving area 3. Preferably, the entire support member 2 is elongated and thereby extends parallel to the longitudinal axis L. The support member 2 preferably forms a base housing of the lamp.

In Fig. 4 is a cross section normal to the longitudinal axis L sketched. Due to its U-shape, the receiving region 3 comprises a first U-leg 31, a second U-leg 32 and one connecting the two U-legs 31, 32

Connecting leg 33. In the example shown, the receiving area 3 is - when the orientation of the lamp is ready for operation - oriented open at the top; The two U-legs 31, 32 thus extend accordingly upwards.

The carrier element 2 is advantageously designed in terms of profile design. Furthermore, the lamp has an LED lighting module 4. In Fig. 4, the LED lighting module 4 is shown separated from the support element 2 or removed.

Starting from the situation outlined in FIG. 4, the LED lighting module 4 for connecting to the carrier element 2, as indicated by a thick arrow P, can be moved from bottom to top against the carrier element 2. The LED lighting module 4 is therefore in the ready state of the lamp at a bottom of the

Carrier element 2 is arranged.

Carrier element 2 separated LED light module. 4

As indicated by way of example in the sectional representation of FIG. 4, the LED lighting module 4 comprises at least one LED 5 for generating a light for one

Light output of the lamp. In the ready state, the LED lighting module 4 is mounted on the support member 2. In the example shown, the LED lighting module 4 is used to generate a downward direct lighting.

To power the LED lighting module 4, the lamp further comprises a contacting element. 6

FIG. 8 shows a view from below against the carrier element 2, that is to say with the LED illumination module 4 removed. The viewing direction corresponds to the arrow P sketched in FIG. 4. The connecting leg 33 of the receiving region 3 has a passage opening 34. The contacting element 6 and the LED lighting module 4 are - in the ready state of the lamp - so electrically conductively connected to each other that this electrical connection passes through the passage opening 34.

The contacting element 6 and the electrical connection are preferably also configured to transmit control signals to the LED lighting module 4.

Furthermore, the lamp is designed so that the LED lighting module 4 is reversibly releasably connected to the contacting element 6. Preferably, the electrical connection between the contacting element 6 and the LED lighting module 4 is designed as a reversibly detachable plug connection. For this purpose, the contacting element 6 advantageously has a socket 62 for this electrical connection to the LED lighting module 4. The bushing 62 may be arranged so that it projects into the passage opening 34 or passes through the latter. The LED lighting module 4 has in this case accordingly a plug 42 for the electrical connection, which - is plugged into the socket 62 - in the ready state. Preferably, the lamp is further designed so that the LED lighting module 4 is arranged tool-less reversibly detachably mounted on the support member 2.

As a result, a particularly simple handling during assembly of the lamp and, where appropriate, in an exchange of the LED lighting module 4 is possible. This holder may, for example, in the form of a magnetic holder and / or a

Federhalterung or designed to be configured via a latching connection. In the example shown, the LED lighting module 4 has a magnet 45 on an upper side for this purpose.

The LED lighting module 4 can therefore very handling friendly of the

Carrier element 2 removed and connected to the latter again. The LED lighting element 4 represents so far as it is a "light component" of the lamp.

5 shows a sketch of the separated contacting element 6 in the manner of an exploded view. Fig. 6 shows a view of the separated one

Contacting element 6 along the longitudinal axis L and Fig. 7 is a corresponding view from below.

The contacting element 6 may, in particular, have a circuit board 61, with the bushing 62 preferably being arranged on the circuit board 61, that is to say integrated so to speak into the circuit board 61.

Further preferably, the contacting element 6 is a spring or

Locking element 65, wherein the lamp is designed such that the Contacting element 6 by means of the spring or latching element 65 on the

Receiving area 3, in particular held between the first U-leg 31 and the second U-leg 32, in particular arranged latching is arranged.

As a result, the assembly of the lamp is facilitated. As shown by way of example in FIG. 4, for this purpose, the two U-legs 31, 32 preferably each have a groove 35 which is open towards the center of the receiving region 3 and into which the spring or latching element 65 is latched, so that the contacting element 6 relative to the carrier element 2 to keep it stable. The contacting element 6 can be placed in this way in the exact position in the receiving area 3 and fix.

In the example shown, the contacting element 6 also comprises a retaining element 66, in particular in the form of a retaining plate, on which the circuit board 61 is fixed, preferably by means of a connecting element such as a screw 67. The spring or locking element 65 can be placed on the retaining element 66 Snap on or arrange over a latching connection.

The described arrangement also makes it possible to achieve a mechanical coding by means of which false installation of the LED lighting module 4 can be reliably prevented.

Overall, the contacting element 6 in conjunction with the

Support element 2 is a prefabricated, fast and tool-free mounting of the contacting element 6 on the carrier element 2. The carrier element 2 is preferably made of a metal, in particular of a good heat-conducting metal, for example of aluminum. For a particularly suitable dissipation of heat generated by the at least one LED 5 during operation of the luminaire, the support element 2 has a planar contact surface 21, in particular pointing downwards, and the LED luminous module 4 has a plan, in particular facing upwards Surface area 41, wherein the plane

Oberfiächenbereich 41 thermally conductive the planar contact surface 21 is arranged contacting. In particular, the LED lighting module 4 may have an upwardly facing outer wall 43, through which the Oberfiächenbereich 41 is formed, wherein the Outer wall 43 consists of a good heat conducting metal, such as aluminum.

In the example shown, the magnet 45 of the LED lighting module 4 is at the

Outer wall 43 arranged so that it extends above the Oberfiächenbereich 41 protruding upward. Preferably, a corresponding (not shown in the figures) recess is provided at the corresponding corresponding point of the support member 2, in which the magnet 45 engages such that the flat surface portion 41 of the outer wall 43 can contact the planar Kontaktfiäche 21 of the support member 2 surface.

The carrier element 2 further preferably has - as is apparent from Fig. 4 - on one, the U-shaped receiving portion 3 opposite side a

Recess 22, in which the LED lighting module 4 is inserted inserted. In the example shown, the recess 22 is accordingly open at the bottom. The plane Kontaktfiäche 21 is formed by the bottom of this recess 22. As a result, a position-fixed arrangement of the LED lighting module 4 can be effected in a particularly suitable manner. The assembly of the lamp is thereby facilitated. As in the example shown, the carrier element 2 is preferably designed like a profile, wherein it has a horizontal main leg, through which both the connecting leg 33 is formed, as well as the bottom of the recess 22nd

This allows a particularly suitable heat dissipation. In this case, the recess 22 is advantageously wider than the receiving area 3, for example, at least twice as wide, are formed by the support member 2 on both sides of the receiving area 3 outer surfaces of the lamp, so that in this way a particularly effective removal of heat in an outdoor area Light is enabled. Preferably, the recess 22 extends over the entire length of the lamp. At the end of the recess 22 at the two longitudinal end portions of the lamp end caps may be provided. As can be seen by way of example from FIG. 1, the receiving area 3

extend approximately over the entire length of the lamp, for example, over at least 80% of the length of the lamp. In the example shown, the recess 22 is elongated, in particular parallel to

Longitudinal axis L designed, wherein it has two lateral boundary walls 221, 222, which also extend parallel to the longitudinal axis L, preferably vertically downwards. The LED lighting module 4 advantageously has two side walls 48, 49, wherein the design is such that the boundary walls 221, 222 of the

Recess 22 in particular as guide surfaces for guiding the side walls 48, 49 of the LED lighting module 4 when mounting the LED lighting module 4 am

Support element 2 are configured. This makes it particularly suitable to achieve a position assurance of the LED lighting module 4 in a direction transverse to the longitudinal axis L. The LED lighting module 4 may, for example, have an overall approximately cuboid shape, wherein the outer wall 43 forms the upper cover surface of the cuboid and the two side walls 48, 49 two side walls of the cuboid.

In Fig. 10 is a side view of an end portion of the lamp sketched and in Fig. 11 is a view of the lamp from below. As indicated by way of example in these figures, in the example shown the luminaire also has a further LED lighting module 4 '. Furthermore, the lamp has a further contacting element for the power supply of the further LED lighting module 4 ', wherein the

Connecting leg 33 has at least one further passage opening 34 ^' and wherein the further contacting element and the further LED lighting module 4 ^{' are arranged} so electrically conductive and thereby reversibly releasably connected to each other, that this another electrical connection, the further passage opening 34 ^' passes. In other words, the electrical connection between the further LED lighting module 4 'and the further contacting element is configured analogously to the first-mentioned electrical connection.

For this purpose, the further LED lighting module 4 ^'is advantageously arranged with respect to the longitudinal axis L adjacent to the first-mentioned LED lighting module 4. In particular, the luminaire may have a total of more than two correspondingly designed LED lighting modules, which are arranged forming a line along the longitudinal axis L, as is sketched in FIG. 11 by way of example for the case of fourteen LED lighting modules. In this case, the design is such that each of the LED lighting modules is supplied via a respective associated, analogously shaped contacting element with power and for the electrical connections between the LED lighting modules and the respectively associated contacting elements each have their own

Passage opening is formed in the connecting leg 33. The

Diaphragm openings can advantageously be formed with an identical distance from one another in the connecting leg 33 for this purpose.

A particularly simple assembly of the lamp or a particularly simple insertion of the LED lighting modules is made possible when the lamp is designed so that the at least one further LED lighting module 4 ^' also in the

Recess 22 is inserted inserted. Accordingly, the LED lighting modules of the lamp are advantageously all designed with the same shape.

The luminaire can furthermore advantageously have an element with a different function instead of an LED luminous module, for example a blank or a blank

Sensor element and so on

Furthermore, it can be provided according to an advantageous development of the invention that at least some of the LED lighting modules 4, 4 ^' optionally in

different orientations, in particular in two rotated by 180 ° degrees orientations on the support element 2 can be arranged. This is particularly useful when the optical elements, so for example, the lenses of the LED lighting module 4 are formed such that they cause an asymmetric light output. In this case, the LED lighting modules 4 respectively located at the end regions of the carrier element 2 should in each case be arranged in different orientations in order to bring about a total symmetrical light output for the luminaire.

The possibility for the optional arrangement of an LED lighting module 4 can be opened in a simple manner that the lighting module 4 two, preferably in each case rotated by 180 ° to each other arranged connector 42 has. In the case of the LED lighting module 4 shown in FIG. 9, a further plug would then be present on the side opposite the illustrated plug 42, so that, depending on

Orientation of the LED lighting module 4 one of the two connectors is coupled to the socket 62 and ensures the power supply for the LEDs. The second - unused - plug, however, then preferably projects into a corresponding opening in the support member 2, but is otherwise inactive.

In the case of several LED lighting modules, the light preferably has to power the LED lighting modules and also for the transmission of

Control signals to the LED lighting modules on an internal wiring, in particular in the form of a wire harness, which is arranged to extend in the receiving area 3. This makes it possible to arrange the internal wiring particularly protected. In addition, it can be achieved in this way that the internal wiring at typical

Viewing the light is not visible, especially not at

Removed LED light module. In this case, only the view of the contacting element 6 is released, as indicated in FIG. 8.

For an advantageous electrical connection between the internal wiring and the contacting element 6, the latter preferably has solder contacts 62 or insulation displacement terminals or the like. These are preferably formed on the board 6.

As indicated in FIG. 1, the receiving area 3 can also be advantageously used for receiving an indirect lighting module 7 for producing an indirect illumination. For this purpose, the indirect light module can be arranged inserted into the receiving area 3, for example, clamped. For this purpose, the indirect light module 7 can advantageously have an elongated, upwardly open, U-shaped basic body, which is arranged in a supported manner between the two U-limbs 31, 32 of the receiving region 3 or clamped. For holding the indirect light module 7, at least one clip or the like may be provided. As a light source, the indirect light module 7 may have at least one LED, for example an LED strip, which is advantageously arranged in the base body. For protection against dust, etc., the indirect light module 7 further preferably has a light-permeable cover which covers the U-shaped base body from above.

Of course, the luminaire may also have at least one further indirect light-emitting module 7 ^' , preferably designed analogously for this purpose, as indicated by way of example in FIG. 1.

Preferably, the LED lighting module 4 or the LED lighting modules are designed to generate both a directed and a diffuse light component, these two components of each individual LED lighting module can be controlled separately. In this way, one user of the luminaire can generate different lighting moods and scenes depending on the light requirement.

An operating device for supplying power to the LED lighting module 4 or the LED lighting modules and optionally the at least one indirect lighting module can also be advantageously used in the receiving area 3.

Also, the at least one suspension element, so for example, the at least one cable 25 can - for example by means of at least one clip - on the

Receiving area 3 or be attached to the two U-legs 31, 32.

In the embodiment described above, the lamp is elongated and represents a long-field lamp so far. However, the lamp according to the invention is not limited to this design. It can also be provided, for example, that the carrier element or the base housing instead of an elongated shape has a rectangular or square or round basic shape.

Furthermore, the luminaire described above is a pendant luminaire. Again, this is not limiting. The light can also be used as a Ceiling recessed luminaire, as a surface-mounted luminaire, as a downlight, as a wall lamp, as a floor lamp, etc.

The basis of the LED lighting module offers the possibility of the varied variance of the luminaire design as a function of the module size of the LED luminaire module.
