The invention relates to a lamp unit for use in a lamp housing of a luminaire, wherein the lamp unit has an elongate profile element, through which a channel is formed with a longitudinal extent, which in a cross-section a first Seitenwandb area, a second side wall portion and one, the side wall portions connecting Floor area, as well as a lighting means for generating a light to be emitted by the lamp, which is arranged in the channel. Moreover, the invention relates to a luminaire with such a lighting unit.

A corresponding lamp is known from DE 10 2008 051 481 AI. In Fig. 17 is a cross section through this known lamp 100 is shown. The luminaire 100 comprises a luminaire housing 200, in which a designed as an elongate profile element

Device carrier 400 is inserted through which a - with reference to the representation in Fig. 17 - downwardly open channel is formed. In the channel, a light source in the form of a fluorescent tube 500 is arranged, which serves to generate a light to be emitted by the lamp 100. The device support 400 and the fluorescent tube 500 accordingly form a "lighting unit" in the sense mentioned at the outset.The light can leave the luminaire through an emission opening 1700 formed by the luminaire housing 200, which is covered by a transparent plate 300. In FIG in perspective, the device carrier 400 shown in separated form.

If one replaces the fluorescent tube 500 in this luminaire 100 by a different type of light source, for example, by LEDs arranged on a circuit board (LED: light-emitting diode), there is the danger that an operator in a

Dealing with the light, especially when the plate 300 is removed, takes damage, namely by unintentional contact of the LEDs or the circuit board.

The invention is based on the object, a corresponding improved

Specify lamp unit or a corresponding improved light. In particular, the lamp unit or the lamp should be designed so that it is better suited for other lamps, such as bulbs in the form of LEDs. This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are indicated in the dependent claims.

According to the invention, a luminaire unit is provided for use in a luminaire housing of a luminaire, wherein the luminaire unit has an elongated profile element, through which a channel is formed with a longitudinal extent, the channel, viewed in a cross section, comprising a first sidewall area, a second sidewall area and having the sidewall regions connecting bottom region; Furthermore, the lamp unit has a lighting means for generating a light to be emitted by the lamp, which is arranged in the channel. In addition, the lamp unit has a light-transmitting contact protection element, which is formed and arranged connecting the side wall portions, such that the lighting means of the side wall portions, the bottom portion and the

Contact protection element is surrounded annularly.

By the contact protection element can be the risk of unwanted

Reduce the contact of the bulb.

Preferably, the lamp unit further comprises a holding element for holding the contact protection element on the profile element, wherein the holding element is preferably designed such that it in a direction transverse to the

Longitudinal extension of the channel presses resiliently against the contact protection element. As a result, a facilitated mounting of the contact protection element on the

Profile element allows.

Preferably, the lamp unit further comprises an end cover element, which is connected at one end of the profile element with the profile element such that it terminates the channel transversely to its longitudinal extent. As a result, a further improved contact protection is possible. In addition, this can be the danger reduce that the light generated by the bulb unintentionally emerges from the lamp without first enforce the contact protection element. Thus, a more homogeneous light emission can be made possible. Advantageously, the end cover element has a preferably

opaque overlap region formed to receive the contact protection element with respect to the channel between the first and second

Side wall portion and the second Seitenwandb area from the outside surrounds.

This allows the probability of a corresponding unwanted

Reduce light output at the respective end region of the channel or the profile element on.

Advantageously, the lamp unit is designed such that the Endabdeckungselement is connected by means of a latching connection with the profile element, wherein the

Detent connection on the part of the Endabdeckungselements comprises a first locking means and on the part of the profile element, a second locking means. By such a locking connection a facilitated mounting of the Endabdeckungselements is made possible on the profile element. The second latching means preferably comprises a recess in the first side wall region and the first latching means a latching arm, which is configured latching engaging in the recess and arranged, preferably with respect to the channel from the outside. This allows a simple and easy to handle design of the locking connection.

Advantageously, the profile element further comprises an outer wall region which, with respect to the channel, the first latching means and the second latching means is arranged surrounding from the outside. As a result, accessibility is limited to the latching connection between the Endabdeckungselement and the profile element, so that a release of the Endabdeckungselements of the profile element is difficult and, accordingly, the risk of unwanted contact of the light source is further reduced.

Preferably, the overlap region comprises a longitudinal edge overlap region which is designed such that, with respect to the longitudinal extension at the level of the first latching means and the second latching means, it has a gap between the first latching means Side wall area and the outer wall area covers. This is the

Accessibility to said locking connection further restricted.

The light-emitting means advantageously comprises at least one LED or consists of at least one LED which is arranged on a circuit board, wherein the end cover element has a pressure arm, which is designed such that it presses an end region of the circuit board against the profile element. This allows improved mounting of the board to the profile element and also an improved dissipation of heat from the LED on the profile element, which can act as a heat sink.

Preferably, the lamp unit further comprises at least one pressing element, which is designed and arranged so that it is the board against the

Press profile element. This makes it possible to produce a secure mounting of the board in a simple manner. In addition, it can be achieved thereby, that the board is pressed against the profile element such that heat, which may be caused by operation of the LEDs, can pass to the profile element in a suitable degree.

Advantageously, the end cover element has an alignment area which is designed to facilitate alignment of the lamp unit with respect to a further, analogously designed lamp unit. In this case, the alignment region preferably comprises a funnel-shaped region, as well as an insertion region, which are designed such that by inserting the insertion region of the

Endabdeckungselements the lamp unit in the funnel-shaped area of a further Endabdeckungselements the other lamp unit, the channels of the two lamp units are aligned without visible offset in the longitudinal direction.

According to a further aspect of the invention, a luminaire is provided, which has a luminaire housing, and at least one luminaire unit according to the invention, which is arranged in the luminaire housing. In this case, the lamp is advantageously designed such that a light exit opening is formed by the lamp housing, through which the lamp to be generated by the light can leave the lamp, wherein the lamp preferably further a translucent

Covering element, which is arranged covering the light exit opening. The invention is explained in more detail below with reference to an exemplary embodiment and with reference to the drawings. Show it:

Fig. 18, the corresponding known lighting unit in a separate form.

In Fig. 1 is a view of an embodiment of a lamp unit according to the invention outlined. The luminaire unit is intended for use in a luminaire housing of a luminaire. The luminaire housing may in particular be a profiled luminaire housing. The luminaire can be a luminaire that can be equipped with a plurality of corresponding luminaire units, so that the luminaire has an overall linear light exit area. Thus, an elongated "light line" may be formed, so that the luminaire may be oblong overall and may, for example, have a length of more than one meter or more than two meters In this respect, the luminaire may in particular have the features known from the prior art mentioned at the beginning.

The lamp unit comprises an elongated profile element 10, for example made of aluminum. The length or longitudinal extension of the profile element 10 can

for example, be between 50 cm and 200 cm. However, other lengths are possible.

In Fig. 6 is a cross section through the profile element 10 is sketched. By the

Profile element 10 is a channel 3 is formed. Due to the elongated design of the profile element 10, the channel 3 has a longitudinal extent L, whose

Direction course is indicated in Fig. 1. In particular, the longitudinal extent L of the channel 3 may be identical to a longitudinal extension of the profile element 10.

For ease of description, it is assumed that the luminaire unit or the luminaire in question is oriented in such a way that the channel 3 is open towards the "down", as indicated by an arrow u in Fig. 6. This results in a main radiation direction which points vertically downwards.

Correspondingly, the arrow o points "upwards", but this is only for the purpose of description

Luminaire unit or the corresponding lamp possible; for example, the Luminaire be arranged on a wall of a room and be provided a light output, which is characterized by a first approximation horizontal main emission. The corresponding directions in the present

In such a case, description must be correspondingly adapted or rotated.

As shown by way of example in the cross-section sketched in FIG. 6, the channel 3 has a first side wall region 31, a second side wall region 32 and a bottom wall region 33 connecting the first side wall region 31 and the second side wall region 32. 6, the channel is accordingly "downwardly open." The channel 3 may have a U-shape, in particular in the cross-section, with the two side wall regions 31, 32 forming the two U-legs.

Furthermore, the lamp unit has a lighting means for generating a light to be emitted by the lamp, which is arranged in the channel 3. In which

Illuminant may in particular be at least one LED, which is arranged on a circuit board 4. For example, a plurality of LEDs may be provided, which are arranged along the longitudinal extent L. Preferably, the board 4 is arranged on the bottom wall portion 33 of the channel 3 and connected with good thermal conductivity with the latter. The profile element 10 may be formed as a heat sink, so that in this way an efficient heat dissipation during operation of the at least one LED is possible.

The luminaire unit can have a converter unit 80, which is arranged on the profiled element 10, or, for short, a converter which serves to supply an externally supplied current for operating the luminaire to one for the luminaire unit or for the luminaire unit

Lamp to implement suitable operating voltage.

Furthermore, the lamp unit has a light-transmitting contact protection element 11, which is designed and arranged to connect the first side wall region 31 and the second side wall region 32. The design is such that the lighting means of the first side wall portion 31, the bottom wall portion 33, the second side wall portion 32 and the contact protection element 11 annular is surrounded. This can reduce the risk of accidental contact with the bulb.

In particular, the contact protection element 11 may be designed in the form of a disk. Preferably, the contact protection element 11 is elongated, designed for example as a profile element, so that it covers the channel 3 over a longitudinal region. Preferably, the contact protection element 11 extends with respect to the longitudinal extent L of the channel 3 according to its destination, at least over the portion occupied by the lighting means.

For example, the contact protection element 11 may have a longitudinal extent that is at least 95% of the longitudinal extent L of the channel 3. The longitudinal extension of the contact protection element 11 may be at least substantially identical to the longitudinal extent L of the channel 3. The contact protection element 11 may for example consist of PMMA (polymethyl methacrylate) or the like, so that in general the thermal expansion properties of the profile element

10 on the one hand and the contact protection element 11 on the other hand. An "at least substantially" identical longitudinal extent of the two components mentioned is of course to be understood in this context.

Advantageously, the lamp unit further has a holding element 14, which is designed to hold the contact protection element 11 on the profile element 10. The retaining element 14 is also shown in FIG. 2, which shows an enlarged detail of FIG. 1.

The retaining element 14 is preferably designed such that it is resilient in a direction R transverse to the longitudinal extent L of the channel 33 against the contact protection element

11 presses. In particular, the design may be such that the retaining element 14 pushes the contact protection element 11 in a direction towards the bottom wall region 33, that is to say with reference to FIG. 6 "upwards".

For facilitated mounting of the contact protection element 11 on the profile element 10, the first side wall portion 31 may include a hanging portion 311 and the second side wall portion 32 a stopper portion 321, such that Touch protection element 11 initially mounted with a longitudinal side in the hooking portion 311 for assembly and then by a tilting movement about a parallel to the longitudinal extent L of the channel 3 extending axis can be rotated until it rests against the stopper area 321, so that in this way the intended position is taken. Then, using the holding element 14, the contact protection element 11 can then be held on the profile element 10 in its intended position.

Preferably, for holding the contact protection element 11 to the

Profile element 10 two or more analogously designed holding elements 14 is provided; As sketched in FIG. 1, two corresponding holding elements 14 can therefore be provided, for example.

Preferably, a locking connection 141 is provided between the holding element 14 and the profile element 10, which is advantageously designed such that a

Manufacture of the latching connection 141 by a simple relative movement between the holding element 14 and the profile element 10 is possible, but not a release. For this purpose, this locking connection 141 - as shown by way of example in FIG. 6 - may be formed in a column area formed by the profile element 10. Of course, as shown, two corresponding latching connections 141, 14 or more may be provided.

By such a configuration can be achieved that the mounted

Touch protection element 11 is virtually impossible to solve without commercial tool from the profile element 10, at least not reversible to solve. The risk of accidental contact of the lamp or the LEDs and the board 4 is thereby further reduced.

The holding element 14 is preferably positioned with respect to the longitudinal extension L in such a way that the delivery of the light generated by the lighting means is impaired as little as possible by the holding element 14. In the case of a plurality of LEDs, therefore, the holding means 14 may be provided, for example, with respect to the longitudinal extent L between two adjacent LEDs. Advantageously, the holding element 14 is designed as a spring element. Further advantageously, the holding element 14 or the holding elements 14 may also be designed to support the lamp unit in the lamp housing. For this purpose, the holding element 14, as shown by way of example in FIG. 6, has two laterally protruding snap arms or projections 142, 142 '. These can be designed to engage corresponding projections in the luminaire housing, as they are known in principle and are sketched by way of example in FIG. 17 with the reference numeral 600. To facilitate handling when inserting the lamp unit in the lamp housing and to remove the lamp unit from the

Luminaire housing, the holding member 14 has two engagement portions 143, 143 ^' , by the compression of which the projections 142, 142' can be moved according to this inward.

By the holding element 14 and the holding elements 14 is the

Contact protection element 11 supported on the profile element 14. However, in principle, a movement of the contact protection element in the direction of

Longitudinal extent L of the channel 3 alone does not reliably prevent this.

In addition, there is a risk that at one end of the

Contact protection element 11 is a free space through which even a touch of the board 4 and the LEDs is possible. This danger can be diminished by the fact that the lighting unit furthermore has an end cover element 20, for example shown in FIG. 2, which is connected to the profile element 10 at one end of the profile element 10 such that it transverses the channel 3 transversely to its end

Length L completes. The end cover element 20 shown by way of example is shown in different views in separated form in FIGS. 7a, 7b, 8a, 8b, 9a and 9b.

In Fig. 4, the lamp unit is shown obliquely from below, Fig. 5 shows an enlarged detail of Fig. 4 about an end portion of the profile element 10. In these figures, the end cover member 20 is designated. Preferably, the end cover member 20 is made of an opaque material and preferably is made of one piece. For example, that can

End cover element 20 made of sheet metal or plastic or be made. Advantageously, the end cover element 20 has an overlap region 7, which is designed such that it separates the contact protection element 11 with respect to the channel 3 between the first side wall region 31 and the second one

Side wall portion 32 engages around from the outside, preferably encompasses continuously. This is apparent, for example, from FIG. 5. In this way, it is possible to prevent the light generated by the luminous means from emerging from the channel at the relevant end region of the channel 3, without first penetrating the contact protection element 11. This would lead to an increased inhomogeneity of the light emitted by the lamp. The end cover element 20 may in this sense preferably be designed such that it completely closes off the channel 3 at the respective end.

Preferably, the Endabdeckungselement 20 is connected by means of a latching connection with the profile element 10, wherein the latching connection on the part of the

Endabdeckungselements 20 comprises a first locking means and part of the

Profile element 10 a second locking means. The first latching means advantageously comprises a latching arm 5 and the second latching means a recess in the first

Side wall portion 31, wherein the configuration is such that the latching arm 5 engages latching in the recess, preferably with respect to the channel 3 from the outside. By a snap connection is a simplified installation of the

End cover element 20 allows the profile element 10.

Advantageously, the profile element 10 further comprises an outer wall portion 35 which - with respect to the channel 3 - the first latching means and the latching arm 5 and the second latching means or the recess in the first side wall portion 31 is arranged surrounding from the outside. For example, the outer wall portion 35 - as is apparent from Fig. 6 - in a first approximation parallel to the first

Side wall portion 31 may be formed. As a result, the aforementioned column area can also be formed in a simple manner, in which the first mentioned

Detent connection 141 between the retaining element 14 and the profile element 10 is preferably formed.

By the outer wall portion 35, the accessibility to the first

Restrict locking means and the second locking means, so that a removal of the End cover element 20 of the profile element 10 is difficult. As a result, the risk of accidental contact with the bulb is further reduced.

An even further restriction of the accessibility to the latching connection between the Endabdeckungselement 20 and the profile element 10 can be achieved if the overlap region 7 comprises a Längsrandüberlappbereich 8, which is designed such that it with respect to the longitudinal extent L at the level of the first locking means and the second locking means covers a gap Z between the first side wall portion 31 and the outer wall portion 35. In particular, this makes it possible to limit the accessibility from below.

Overall, can be achieved by the above features that the

Endabdeckungselement 20 can not be reversibly removed or separated from the profile element 10 practically with commercial tools.

Preferably, the end cover member 20 has a pressing arm 6 which is configured to press an end portion of the board 4 against the profile member 10. This makes it possible to improve the mounting of the board 4 on the profile element 10. In addition, can be caused by the pressure thus generated a particularly good thermal transition between the board 4 and the profile element 10. In this way, a dissipation of heat, which is generated by the latter when the LED is active, is improved on the profiled element 10. The profile element 10 can accordingly have a function as a heat sink. The wall thickness of the

Profile element 10 is selected such that it is at a location where the at least one LED or corresponding board is arranged, the largest and then decreases in the course to the outside. This is a particularly good

Achieve heat dissipation.

The profile element 10 can furthermore advantageously have a further outer wall region 35 ', by means of which, in conjunction with the second side wall region 32, a further intermediate space Z' is formed. Preferably, the profile element 10 - as indicated in Fig. 6 - formed symmetrically about a plane of symmetry S. Analogously, the end cover element 20 may advantageously have a further latching arm 5 'and / or a further longitudinal edge overlap region 8' and / or another one Andrückarm 6 '. Again, the design can be symmetrical to the

Be symmetry plane S.

The end cover member 20 may also include other elements, such as a holder for a status LED.

As outlined by way of example in FIGS. 4 and 5, the lighting unit preferably also has at least one pressing element 40, which is designed and arranged such that it presses the circuit board 4 against the profile element 10.

In this way, a suitable mounting of the board 4 on the profile element 10 also in a central region of the channel 3 can be effected. Fig. 13 shows an enlarged section of Figure 4, Figure 14 is a corresponding view from below. Figures 15a and 15b show the pressing member 40 in separated form from two different angles.

The lighting unit may also include a plurality of boards 4, which are arranged along the channel 3 in a row. In this case, a plurality of pressing elements 40 for holding the boards 4 to the profile element 10 are suitable.

Preferably, a latching connection is again provided for holding the pressure element 40 on the profiled element 10, so that the pressure element 40 can be easily mounted on the profile element 10. For this purpose, the pressing element 40 may have a latching means 41 which on a corresponding projection 42 on

Profile element 10, for example, on the bottom wall portion 33 for the preparation of the locking connection can be engaged. Preferably, this has

Pressing element 40 for generating a uniform pressure on the board 4 also has a further analogously formed locking means 4Γ. In particular, the pressing element 40 can again be designed to be symmetrical, as shown by way of example in the figures, again in turn with respect to the plane of symmetry S.

As hinted suggestively by way of example from FIGS. 6 and 15b, preferably the pressing element 40 has a slightly upwardly curved area between the two locking means 41, 41 'transversely to the longitudinal extent L, so that it is biased such that it presses the board 4 against the profile element 10 when it is arranged as intended on the profile element 10. In this case, a direct contact between the pressing member 40 and the board 4 may be provided, but it may also be provided that at the relevant point between the

Pressing element 40 and the board extends another component, such as a reflector.

The design is advantageous in that the pressure exerted by the pressing member 40 on the board 4, over the life for which the lamp and / or the lamp unit is designed, can be maintained.

Further advantageously, the pressure element 40 has at least one pressure arm 42 with a pressure surface 43, which is designed for pressing contact with the circuit board 4. This allows a particularly uniform pressure distribution over the surface of the board 4 away. The pressure surface 43 is preferably convex, as shown for example in FIG. 15b. This makes it possible that the board 4 against the pressing member 40 in the direction of

Longitudinal extent L of the channel 3 can move smoothly, without thereby the required pressure would be limited. This is advantageous with respect to possible different longitudinal expansion properties between the board 4 on the one hand and the profile element 10 on the other. In order to enable such a compensating movement, the board 4 is preferably supported floating on the profile element 10, in particular only by the at least one pressing element 40 and optionally the at least one Andrückarm 6 of Endabdeckungselements 20 and optionally at least one Andrückarm another, analogously designed Endabdeckungselements the opposite end of the channel 3.

The pressure arm 6 of the Endabdeckungselements 20 and the Andrückarm 42 of the pressing member 40 are preferably formed analog.

The pressing element 40 preferably has at least two pressing arms 42, 42 ^' whose Druckf surfaces with respect to the longitudinal extent L a distance from each other, which is preferably greater than a width of the channel 3rd

This further allows a particularly uniform pressure distribution.

For example, the pressing element 40 - as shown in the figures - four Andrückarme 42, 42 ^' , 42 ^" , 42 ^"' , wherein two of the Andrückarme

are formed symmetrically with respect to the plane of symmetry S to the other two of the four Andrückarme.

The profile element 10 can advantageously also be designed as a reflector, that is to say have a reflective surface area. Accordingly, that can

Profile element 10 so fulfill the functions holding element, heat sink and reflector.

However, the luminaire unit can also optically have a separate reflector 60, which is designated as an example in FIGS. 4 and 5, which is generally oblong and which extends along the channel 3. Such a separate reflector 60 can be designed with a particularly high ref exionsgrad, which is advantageous with respect to the efficiency of the lamp unit.

As can be seen from FIGS. 6, 13 and 14, the reflector 60 is preferably arranged resting on the at least one circuit board 4. In this case, it advantageously has a cutout 61 which extends around several or around one of the LEDs 50 and which is also so large that the at least one pressing arm 42 of the

Pressing element 40 or the at least one Andrückarm 6 of the

Endabdeckungselements 20 presses with the relevant pressure surface through the cutout 61 directly on the relevant board 4. As a result, a floating support of the reflector 60 is made possible, which is advantageous with respect to possible different thermal expansion properties between the reflector 60 on the one hand and the profile element 10 on the other. For example, in each case a correspondingly shaped cutout 61 can be provided in each case by one LED 50 or in each case a specific number of LEDs. Preferably, the reflector 60 is so wide that it extends substantially from the first side wall portion 31 to the second side wall portion 32, that is, for example, at least 80%. As mentioned above, a light can be provided which can be equipped with a plurality of corresponding lighting units. The luminaire housing can be designed profile-shaped, wherein the plurality of lamp units can be arranged in a row in the luminaire housing. In this case, it is usually desirable to design the luminaire so that the transition between two

adjacent luminaire units shows no apparent inhomogeneity in the output of light. For this it is desirable that the two adjacent

Luminaire units are aligned relative to each other such that the two respective channels of the lamp units are as possible lying without lateral offset, so lying on a common line.

In FIGS. 10 to 12, two end cover elements 20, 20 'are shown-in each case separated from the respective profile elements-from different angles of view, which are aligned or positioned relative to one another in this sense. In order to facilitate the production of a corresponding relative arrangement of two lamp units, it is advantageous if the end cover element 20 a

Aligning region 9, which is adapted to align the

To facilitate lighting unit with respect to the other, analogously designed lighting unit. The alignment region 9 preferably has a funnel-shaped region 91, and a preferably rib-shaped insertion region 92, which are designed in such a way that insertion of the insertion region 92 of the

Endabdeckungselements 20 of the lamp unit in the funnel-shaped portion of the other Endabdeckungselements 20 'of the other lamp unit, the channels of the two lamp units are aligned without visible displacement in the longitudinal direction.

For the electrical connection of two adjacent lighting units in the luminaire, it may be provided, for example, that the luminaire units are internally bridged by electrical cables, which are connected by an end-side end region of the luminaire units first lamp unit lead to the corresponding adjacent end-side end portion of the second lamp unit. This will be explained in more detail with reference to FIG. 16; Here, a variant A of the lamp unit is sketched, which has an electrical wiring 70, which may comprise a plurality, for example seven, electrical wires. The wiring 70 is preferably on one side of the profile element - here referred to as a variation with 10 '- out.

On one side of the profile element 10 ^' opposite the light source, in this case on an upper side, one or the above-mentioned ones are already mentioned above

Converter unit 80 arranged for the boards 4 of the relevant

Lamp unit A converts the externally supplied power to operate the lamp in a suitable operating voltage.

Of one of the end portions of the lamp unit A can thereby a

Branch lead the wiring 70 to the converter unit 80 lead.

Preferably, the wiring 70 is - with respect to the channel 3 - on one

Outside arranged on the profile element 10 ', for example - in the above

described outside of the first side wall portion 31 or on the second side wall portion 32 or, more preferably, on the outside

Outside wall portion 35 or on the other outer wall portion 35 '. As a result, the wiring 70 can be arranged comparatively far away from the possible heat or heat sources in the form of the LEDs 50 and / or the converter unit 80, so that the risk of heat being adversely affected by the wiring 70 is reduced.

For the frontal electrical connection of two adjacent lamp units, a corresponding electrical connection element 90, for example in the form of a plug, may be provided. As a result, easier assembly is possible because not individual wires must be connected, but with the electrical

Connecting element 90 by only one plug operation, the electrical contacts can be made as intended. Alternatively, a corresponding plug-socket system can be firmly connected to the lamp units or formed as part of the lamp units. This can be practically avoided that a corresponding electrical connection element 90 is lost during assembly.

In the case of variant A, six blanks 4 are provided by way of example, four blanks 4 in variant B and only one printed circuit board 4 in variant c.

Furthermore, an example of a luminaire housing 98 is indicated in FIG. 16, into which the luminaire unit or a plurality of luminaire units can be inserted or

can. Through the luminaire housing 98, a light exit opening 95 is formed, through which the light to be generated by the luminous means or the LEDs can leave the luminaire. Furthermore, the lamp advantageously has a translucent cover element 91, which is arranged to cover the light exit opening 95 or can be. By covering element 91, a further homogenization of the light to be emitted by the luminaire can be achieved. In particular, this is also possible at the transition between two adjacent lighting units; In this way, it is possible to achieve a quasi-continuous line of light through a plurality of luminaire units arranged in series.

It may alternatively be provided that within the lamp housing, a bus bar is arranged, and the lamp unit a, in the figures 2 and 6, indicated, downstream handle element 81 which is designed to tap current from the busbar, for example via a snap connection. This alternative embodiment has the advantage that a lamp unit with respect to the longitudinal extension of the lamp housing 98 can be used practically at any point; In particular, this does not require specific distances

adjacent lighting units are taken into account, so it can, for example, an arbitrarily long designed "interruption" between two adjacent

Be provided lighting units. For example, it is also possible to provide a "dummy piece" or a spotlight between two adjacent light units, and, for example, see FIG.

The busbar can advantageously be arranged above or alternatively laterally in the lamp housing 90.
