  • control arrangement 10 is accommodated in a space-saving manner.
  • the end section 6 with the circular-cylindrical outer contour can be fastened in an expedient manner, whereby at the same time the control arrangement 10 is also separated from the fastening device 55, in particular by the mounting part 64 and the cover part 65 is covered.
  • the control assembly 10 is thus "hidden” in an aesthetic manner, without having to accommodate a separate housing for it or complicating the fastening of the tubular lighting device 1.
  • light is preferably emitted uniformly and continuously over the visible extension of the lighting device 1, which corresponds to the light-emitting section 3.
  • the lighting device 1 is supplied with electrical energy via the elongated end section 6 .
  • the in 8 shown already mentioned external converter 78 is provided.
  • control signals are supplied to the lighting device 1 via the end section 6 .
  • 8 shows schematically the coupling of the lighting device 1 mediated via the converter 78 to the power supply (conductor L, N) and to control lines (conductor DA).
  • the mounting part 64 has an opening 69 in which the end section 6 can be accommodated to a significant extent along its longitudinal extension L6 and clamped to the mounting part 64 in order to fix it.
  • the shape of the opening preferably corresponds to the above-described outer shape of the end section 6 and is circular, for example.
  • a clamping device is provided, comprising the two clamping elements 67 designed as clamping screws.
  • the end section 6 can protrude somewhat from the assembly part 64, this part not being visible to the viewer after assembly is complete and facing away from the visible side of the fastening device 55.
  • the end section 6 is inserted into the opening 69 of the mounting part 64 in such a way that the cable 15 emerges from the mounting part 64 on the rear side of the fastening device 55 that is not visible in the installed state. After the end section 6 has been positioned in the opening 69 , the end section 6 is clamped in the mounting part 64 by means of the clamping elements 67 and is thus fixed to the mounting part 64 .
  • the mounting part 64 is also fastened to another element, in particular to a plate-shaped component 85 in the example shown, such as an intermediate ceiling or a drywall built in front of a solid wall, also by means of clamps.
  • a plate-shaped component 85 in the example shown, such as an intermediate ceiling or a drywall built in front of a solid wall, also by means of clamps.
  • an opening can be formed in the plate-shaped component 85, into which the fastening device 55 and the end section 6 accommodated therein are inserted in sections.
  • the cable 15 is led out on a non-visible side of the plate-shaped component 85, with the converter 78 also being able to be located on this side of the plate-shaped component 85.
  • Each of the clamping elements 66 has a surface 71, while the mounting part 64 either itself or the cover part 65 has a projection 70.
  • the surfaces 71 can be moved relative to the overhang 70 and thus adjusted or adjusted in their position.
  • the mechanism 68 can have a screw element 72 in each case, by turning which the clamping element 66 can be adjusted along the screw element 72 .
  • the assembly part 64 can thus be fixed to the plate-shaped component 85 for fastening with the aid of the respectively movable clamping elements 66 .
  • the lighting device 1 is fixed in the area of the end section 6 to the wall or the ceiling, or alternatively to a floor.
  • the lighting device 1 can also be fixed in a manner that is not shown in more detail at the second end already mentioned above, and this can also be carried out by clamping or in some other way.
  • attachment by means of clamps through or on the surfaces 71 does not necessarily have to be provided, but instead it can be provided that the mounting part 64 is attached to the other element, such as the wall, floor or ceiling, for example the plate-shaped component 85, for fastening the lighting device 1 to the end section 6, for example by means of screws.
  • the mounting part 64 is covered in a pleasing manner by the cover part 65 after the end section 6 has been fixed therein by clamping and after the attachment to the plate-shaped component 85 described above.
  • the end section 6 thus serves both to fasten the lighting device 1 and to accommodate the control arrangement 10
  • control arrangement 10 or the PCB 28 makes it easier to use different attachment options on the end section 6 .
  • no separate housing has to be created for the control arrangement 10 or PCB 28, which then has to be attached outside the lamp (eg in a false ceiling or in front of it, behind a drywall or on it, etc.).
  • the cabling 15 can be routed elegantly and in a space-saving manner through, for example, a narrow tube without a PCB 28 having to be accommodated therein (or in front of it).
  • the end piece 6 of the light tube 1, which contains the control arrangement 10, and therefore the equipped PCB 28, is completely or at least partially received by the fastening device 55 for the tube 1, so that the transparent tube 1 in the installed state is continuous along its visible extent in the light emitting portion 3 and emits light substantially uniformly.
  • control arrangement 10 of the lighting device 1 is electrically coupled to the converter 78 and to the light-generating arrangement 21 .
  • the control arrangement 10 is thus arranged along a path of the electric current between the converter 78 and the light generating arrangement 21 .
  • the external converter 78 can, for example, be arranged behind the panel-shaped element, such as the false ceiling.
  • control arrangement 10 can be equipped with further functions which go beyond the control of the LEDs 23 or the light-generating arrangement 21 described above.
  • the lighting arrangement 100 can comprise a plurality of tubular lighting devices 1 which can be supplied jointly by the external converter 78 .
  • a light generating arrangement 100' is shown schematically 9 .
  • the lighting devices 1 can be controlled individually, or it can, see 9 , be provided that some or all of the plurality of tubular lighting devices 1 are assigned to a control group SG, such that the control group SG assigned lighting devices 1 can be controlled together.
  • a control group SG two or more tubular lighting devices 1, as described above, each with a light-generating arrangement 21 with a plurality of LEDs 23, can be combined for joint control analogous to that described above for the lighting device 1.
