Description

FIELD OF THE INVENTION

The invention relates to the field of lighting devices and in particular to a tubular lighting device. In addition, the invention relates to a

Lighting arrangement with such a tubular lighting device.

TECHNICAL BACKGROUND

Although the invention can be useful in many areas in which it is desired to achieve a lighting effect, the invention and the problem on which it is based are to be explained below using the example of a lighting device for achieving an aesthetic lighting effect, particularly in an interior

room of a building, are explained in more detail.

It is generally known to provide luminaires or luminous elements in an interior area of a building, not only to illuminate a space, i. H. to illuminate, but also to achieve an aesthetic effect and/or to diversify the light emission in different areas of the room. With conventional lighting devices, there are limitations with regard to flexible design of the lighting effects, and on the other hand, installation and supply of the lighting device are conventionally less simple and flexible, as well as less elegant and space-saving than

this would be desirable.

This situation needs to be improved.

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of providing a lighting

specify direction that is arranged in space in a simple and varied way and

can be mounted, with the simplest possible, space-saving attachment

correspondingly improved lighting arrangement are specified.

According to the invention this object is achieved by a tubular lighting device with the features of claim 1 and / or by a lighting arrangement with the

Features of claim 18 solved.

A tubular lighting device with a light-emitting section and an end section is proposed. In the light-emitting section, the lighting device has a light-generating arrangement which, during operation, enables light to be emitted in the region of the light-emitting section. The end section is set up to supply the lighting device with electric current for the operation of the light-generating arrangement. Furthermore, the lighting device has a control arrangement, which is arranged inside the end section and is accommodated in a body of the end section, for controlling the light-generating arrangement

on.

Also proposed is a lighting arrangement comprising such a tubular lighting device and at least one fastening device for the tubular lighting device. In this case, the tubular lighting device is fastened to the end section of the tubular lighting device by means of the fastening device, with the end section being supplied with electrical power for the operation of the tubular lighting device

and/or is provided with control signals.

One idea on which the invention is based is to integrate the control arrangement in an end area of the tubular lighting device (“light tube”). Such an integration of the control arrangement makes it considerably easier to attach the tubular lighting device. In particular, when assembling the tubular lighting device, there is no need to consider a separately provided component for controlling the light-generating arrangement. Furthermore, with the invention it is not necessary to use your own

to provide a separate housing for such a control arrangement. a separate

be done economically.

Advantageous configurations and further training result from the sub-

Claims and from the description with reference to the figures.

In one configuration, the end section is designed as a fastening section of the lighting device for fastening the same at least by means of the end section. Thus, the end section can take over both the functions of fastening the lighting device and accommodating the control arrangement.

men, which in turn saves space.

In a further development, the end section is set up to be received by a fastening device for the lighting device, and here in particular by a mounting part of the fastening device, for fastening the lighting device at least partially or essentially completely along a longitudinal extent of the end section. In this way, for example, the end section with the control arrangement integrated therein can be covered aesthetically and expediently by the fastening device or the mounting part, such that the light emission section of the tubular lighting device in the installed state is continuous, for example, along its visible extent and, in particular, largely uniform , can emit light. on

in this way, particularly aesthetic lighting effects can be achieved.

According to one embodiment, the end section can be clamped for fastening. the

End section can, for example, after partial or substantially complete

simple and expedient fixation of the lighting device can be achieved.

In particular, in a development, the end section can adjoin the light-emitting section, preferably essentially directly. In this way, the integration of the attachment, the supply and control, and the light emission by the lighting device can be carried out in a particularly compact and space-saving manner

be reached.

According to one embodiment, the end section is formed with an outer shape with a substantially circular cross section, in particular with a substantially cylindrical outer shape. Such a configuration of the outer shape of the end section can advantageously contribute to fastening the end section in different ways. Different ways of fastening the end cap

sections are possible without the control arrangement being a hindrance.

According to a further alternative or additional configuration, the end section is designed with an outer transverse dimension, in particular an outer diameter, which essentially corresponds to an outer transverse dimension, in particular an outer diameter, of the light-emitting section. This can contribute to expedient production of the lighting device, especially since, for example, an outer shape of the light-emitting section can be continued unchanged into the end section. For example, a, for example, circular outer contour of the tubular lighting device in the light emission section and

be essentially the same in the end section.

It should be noted that the end section and/or the light-emitting section of the lighting device in other configurations can each be formed with an outer shape that has a cross-section that deviates from a circular shape, for example an oval cross-section, a polygonal cross-section, for example with rounded corners, or another

desired cross-section.

deviate in sections.

In a preferred embodiment, the control arrangement is entirely contained in the body of the end section. The control arrangement can thus be accommodated in a space-saving manner, while at the same time the end section can be designed, for example, with a standardized outer contour and essentially without parts of the control arrangement protruding from the outer contour, which further facilitates attachment. In addition, the control arrangement is based on this

Way well protected housed.

In a further development, the body of the end section is designed to be essentially solid, in particular as a solid silicon body, with the control arrangement preferably being integrated into the body in such a way that the body controls the

tion arrangement substantially completely surrounds.

In particular, in a development, the light emission section and the end section are formed with a common silicon body. The light-emitting section and the end section with the control arrangement accommodated therein can be manufactured in an expedient manner, for example, and the control arrangement can be expediently integrated into the silicone body without the need for a step of fastening the end section to the light-emitting section.

In a further development, the light-generating arrangement is formed with a strip-shaped component in an interior of the light-emitting section, light-generating devices, in particular LEDs, being arranged spaced apart from one another, being provided on this component. In particular, conductors can also be provided on or on the strip-shaped component, with the help of which the light

generating devices connected to the control arrangement and/or to one another

full and energy-saving way.

According to one configuration, one or more conductors, in particular a cable, are led out of the end section parallel to an axial direction, in particular in the region, on a front end of the end section that is distal from the light emission section and is designed as one end of the tubular lighting device a front end surface of the end section and preferably centrally in the area of a longitudinal axis of the end section. The conductor or conductors, which are preferably insulated, can be provided for the electrical lighting device

To supply power and / or to supply control signals to the control arrangement.

In a further development, the tubular lighting device is set up to be supplied with electrical energy via the end section, which is provided by a converter provided outside the tubular lighting device. The converter can thus be arranged at a distance from the tubular lighting device. Thus, the slender shape and the simple, flexible and versatile attachment of the lighting device is not impaired. In addition, it can be made possible, if necessary, several lighting devices over one

to supply common converter with electrical energy.

In a further configuration, the control arrangement is set up to receive a control signal and the light-generating arrangement and/or an individual light-generating device and/or a plurality of individual light-generating devices of the light-generating arrangement and/or groups of these light-generating devices of the light-generating arrangement, for example an LED or

LEDs to be controlled depending on the control signal.

In further configurations in particular, the control arrangement can be set up to process and/or evaluate and/or interpret the received control signal, for example by means of a computing device,

such as a microprocessor.

head for

Furthermore, in a further configuration, the control arrangement can be set up to dim the light-generating arrangement and/or the individual light-generating device(s) and/or the groups of these light-generating devices as a function of the control signal. In an alternative or additional refinement, the control arrangement can be set up to determine a color and/or a color temperature of a light emitted by the light-generating arrangement and/or the individual light-generating device(s) and/or the groups of these light-generating devices, depending on the control

set or change the signal.

For example, in configurations, the light generating device(s), for example the LED(s), can be activated by means of pulse width modulation (PWM), for example 48 volt PWM, 24 volt PWM or 12 volt PWM.

In particular, the control arrangement can be set up to control the light-generating arrangement and/or the individual light-generating device(s) and/or

to dim their groups electronically under microprocessor control.

In one embodiment, the control arrangement has a printed circuit board, which in particular

is especially equipped with electronic components.

In one embodiment, the printed circuit board is surrounded on all sides by a material, in particular a silicone material, with which the end section is formed, with conductors for coupling the control arrangement to the light generator

tion arrangement and with an external source of electrical energy and / or of

Way mechanically fixed.

In one embodiment, the printed circuit board is completely opened up in the end section

taken.

In a further embodiment, the printed circuit board is designed to be elongated and a longitudinal extent of the printed circuit board is arranged parallel to a longitudinal axis of the end section. The printed circuit board can be rectangular, for example. In this case, the printed circuit board can also be designed, for example, with an aspect ratio of the longitudinal extent to the transverse extent of the printed circuit board of between approximately 2 and approximately 10, in particular such an aspect ratio of between approximately 3 and approximately 6, for example an aspect ratio of between approximately 4 and approximately 5. Components for forming the control arrangement can be arranged on such a printed circuit board, with the printed circuit board designed in this way being in the end section of a particularly slim and elongated tubular light

device can be accommodated advantageously.

According to a further embodiment, the printed circuit board is essentially arranged following a plane that is spanned by a longitudinal axis and a diameter of the end section. In particular, in this way the cross section of an end section designed with a round outer shape can be used effectively to accommodate the printed circuit board and thus the control arrangement.

In particular, a longitudinal extent of the light-emitting section can be significant

According to one embodiment, the end section is also elongate. In this way, a reliable attachment can be made possible by means of the end section, and space is also created for the control arrangement in the end section.

In particular, the tubular lighting device is elongated.

The tubular lighting device can have a further end section at a distance from the end section, which can be used for further attachment. Preferably, however, the control unit is only in the first-mentioned end section

housed in order.

In one configuration, the lighting arrangement includes a plurality of tubular lighting devices and also an external converter. In this case, some or all of the majority of the tubular lighting devices can be supplied with electrical energy by the external converter. Thus, only one converter is required to supply several lighting devices, whereby the energy

Furthermore, in a further configuration, the lighting arrangement comprises a plurality of tubular lighting devices, with some or all of the plurality of tubular lighting devices being assignable to a control group and being controllable together. This can be the control of the lighting devices

The above configurations and developments can be combined with one another as desired, insofar as this makes sense. Further possible configurations, developments and implementations of the invention also include combinations of features of the invention described above or below with regard to the exemplary embodiments that are not explicitly mentioned.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

1 shows a tubular lighting device 1, which in this example can also be referred to as a “silicone light tube”, according to an exemplary embodiment, with a light-emitting section 3 and an end section 6 directly adjoining the light-emitting section 3 being shown. The tubular lighting device 1 can be attached to a second, remote from the end section 6 and not shown in FIG.

showed end have another end portion.

The end section 6 is designed as a fastening section for fastening the lighting device 1 by means of the end section 6 . The additional, second end section not shown in FIG. 1 can also be designed as a fastening section

be to attach the other end of the tubular lighting device 1.

The tubular lighting device 1, see e.g. FIG.

Section 3 and the end section 6 essentially constant outer cross-

cut is formed. The end section 6, see e.g. B. Fig. 1 or 2 is also elongated, wherein

a longitudinal extension of the light-emitting section 3 is substantially greater than one

Longitudinal extension L6 of the end section 6, see also Fig. 5B.

The tubular lighting device 1 is designed to be flexible, which means that there is a fastening device 55 (not shown in detail in Fig. 1) for fastening the first end section 6, a further fastening device that may be provided for fastening the second end section (not shown), and, if desired, additionally provided and 1 also not shown further fastening devices for fixing the light emitting section 3 at one or more intermediate position (s), allow to arrange the lighting device 1 in a variety of, for example, three-dimensional shapes in a room, such as an interior of a building. The end sections of the lighting device 1 and in particular the end section 6 can/can here in the area of a ceiling, in the area of a wall or

be fixed in the area of a floor of such a space.

A longitudinal axis 2 of the tubular lighting device 1 in FIG. 1 follows a longitudinal center line of the lighting device 1 along the example of a curved course of the lighting device 1. In FIG. 1, the longitudinal axis 2 is indicated with a dot-dash line. The longitudinal axis 2 also forms the longitudinal axis of the light-emitting section 3 and of the end section 6.

The lighting device 1 is configured such that it can emit light in the light emitting portion 3 . The lighting device 1 is preferably set up in such a way that during operation it is essentially along the entire longitudinal extent of the

Light emitting section 3 emits light evenly and continuously.

In order to generate the light that is to be emitted during operation of the lighting device 1 in the area of the light-emitting section 3 , the lighting device 1 has a light-generating arrangement 21 in the light-emitting section 3 . The light-generating arrangement 21 is formed with a strip-shaped component 22 on which spaced-apart LEDs 23 are arranged as light-generating devices. The strip-shaped component 22 can serve as a carrier for the LEDs 23 and for conductor tracks or similar conductors, by means of which the LEDs 23 are supplied with electrical current and/or are connected to one another. The band-shaped component 22 is arranged in an interior of the light-emitting portion 3

and shown schematically in Figures 6 and 8. The band-shaped and preferably fle-

xible component 22 can also be referred to as "LED PCB" * "where PCB for

“printed circuit board” says.

A supply of the lighting device 1 with electric current for the operation of the light-generating arrangement 21 is provided in the area of the first end section 6, with the end section 6 being set up for this purpose. On a front end 7 of the end section 6, which is distal from the light-emitting section 3 and which also forms a first end of the tubular lighting device 1, there are several insulated conductors 19, four in this case by way of example, which are combined to form a cable 15, for example, or individually can run, from the end portion 6 parallel to an axial direction thereof, thus along the longitudinal axis 2, led out. The conductors 19 of the cable 15 thus emerge from the end section 6 at the distal end 7 of the end section 6 in the area of the front end face of the end section 6 , preferably in the center in the area of the longitudinal axis 2 . The cable 15 with the conductors 19 is used to supply the lighting device 1

with electricity and with control signals.

In order to control the light-generating arrangement 21 , the lighting device 1 has a control arrangement 10 which is arranged inside the end section 6 and is accommodated by a body 36 of the end section 6 . The accommodation of the control arrangement 10 in the end section 6 is to be referred to below

2 to 7 in particular.

The end section 6 has an outer shape whose cross section is essentially circular and is essentially constant along the longitudinal extent L6 of the end section 6 . Thus, in the example shown, the end section 6 has a substantially cylindrical outer shape, in particular a circular-cylindrical outer shape.

reindeer form. In particular, Fig. 5A also shows that the end portion 6 with an outer

Diameter D6 is formed, which corresponds to an outer diameter D3 of the light

submission section 3 essentially corresponds.

Thus, in the shown embodiment, the outer cross-sectional shape of the light-emitting portion 3 and that of the end portion 6 are the same, but this may be different in other embodiments. Also are working examples

conceivable in which the outer cross-sectional shape of end section 6 and/or light

t delivery section 3 deviates from the circular shape.

The body 36 of the end section 6 is designed as a solid silicon body which essentially completely surrounds the control arrangement 10 . Thus, the control assembly 10 is fully contained within the body 36 of the end portion 6 . It should be pointed out again that in Figs. 3 and 4 the end section 6 is only cut open along its longitudinal central axis for illustration purposes and is therefore only shown in half in Figs. 3 and 4 in order to show the embedding of the control arrangement 10 in the body 36 of the end section 6 to show It goes without saying

that the control arrangement 10 is completely surrounded by the body 36 .

The control arrangement 10 is designed as a control unit with a printed circuit board 28 . In particular, the printed circuit board 28 is equipped with electronic components 31 here. The components 31 are connected to one another on the printed circuit board 28 to form the control arrangement 10, for example with the aid of conductor tracks which are not shown in detail in the figures. For the sake of a better overview, not all electronic components 31 are provided with reference symbols in the figures. The control arrangement 10 can thus also be used as a control PCB

where PCB stands for "printed circuit board".

The printed circuit board 28 with the components 31 located thereon is completely accommodated by the silicone body 36 and thus in the end section 6 . In this case, the circuit board 28 along with the components 31 is surrounded on all sides by the silicone material with which the body 36 is formed. Thus the printed circuit board is 28

mechanically integrated into the end section 6. In the exemplary embodiment shown, the control arrangement 10 with which the power

spaced mounted LEDs 23 inside the light emitting portion 3 and

an external converter 78 shown only in FIGS. 8 and 9, for example a converter from 230 volt mains voltage to 48 volt output voltage for the operation of the lighting device 1, interposed. The external converter 78 is arranged outside the tubular lighting device 1 and can be a lighting device 1, as in FIG. 8, or several lighting devices 1 together, as in FIG.

supply.

In order to couple the control arrangement 10 and the circuit on the printed circuit board 28 formed with the aid of the electronic components 31, on the one hand to the light-generating arrangement 21, and on the other hand to couple the control arrangement 10 to the converter 78 as an external source of electrical energy and to an external source of control signals, see for example Figures 6 and 8, conductors 45 and 46 leading from the circuit board 28 to the strip-shaped component 22, and from the opposite end of the circuit board 28 to the distal end 7 of the end section 6 conductors 19a-19d, through the silicone material of the body 36 is passed through.

Thus, the printed circuit board 28 with components 31 thereon and also the

Head 19a-d, 45, 46 held mechanically and protected against external influences.

The circuit board 28 with the electronic components 31 and the conductors 45, 46, 19a-d can in the manufacture of the end portion 6 in the silicone material which

the body 36 forms, for example, be cast.

The printed circuit board 28 is rectangular and elongated, with a longitudinal extension L28 of the printed circuit board 28 being arranged parallel to a longitudinal axis of the end section 6 which coincides with the longitudinal axis 2 of the lighting device 1 . The circuit board 28 is thus formed as an elongated flat plate on which

the electronic components 31 are arranged. For example, the ratio L28/B28 of the longitudinal extent L28 of the ladder

plate 28 to a transverse extent or width B28 of the circuit board 28 between about

2 and about 10, more specifically between about 3 and about 6. In the one shown

For example, the aspect ratio L28/B28 is between 4 and 5. Such an elongated

trained printed circuit board 28 can be inserted into the end section 6 to save space.

The printed circuit board 28 is arranged within the end section 6 in such a way that it essentially follows a plane that is spanned by a longitudinal axis of the end section 6 that coincides with the longitudinal axis 2 of the lighting device 1 and a diameter of the end section 6, which is cylindrical in terms of its external shape. In this way, the space available within the end section 6 for accommodating the printed circuit board 28 is advantageously

used.

The length of the lighting device 1 along its longitudinal axis 2 can be up to about 10 meters in the exemplary embodiment shown, with the control arrangement 10 making it possible to have a light-generating arrangement 21 in a light-emitting section 3, which occupies most of the lighting device 1, which is up to 10 meters long. head for. Arrangement 21 is thus controlled for the entire length of lighting device 1 via control arrangement 10 in end section 6.

The silicone body 36 can be part of a uniform silicone body common to the light-emitting section 3 and the end section 6, whereby end section 6

and light-emitting section 3 need not be specially fixed to each other in a separate step. In sections 3 and 6, the silicone body could

be produced, for example, in a common shaping step.

During operation, the control arrangement 10 receives control signals which are provided externally for controlling the lighting device 1 . The control signals can be provided in a wired manner, as in Figs. 8-9 via conductors 19c-d, or in variants wirelessly instead. The control signals can be based on the DALI protocol, or the DMX protocol, or the ZigBee protocol, or the 0-10V protocol, for example. If the control signals are provided wirelessly, the ZigBee protocol can be used, for example, in which case

the conductors 19c-d can be omitted. In the case of a wired deployment

In one example, the DALI protocol can be used for communication via the conductors 19c-d

come.

With the aid of the control arrangement 10, the light-generating arrangement 21 and/or its individual LEDs 23 and/or groups of these LEDs 23 are driven as a function of the control signals and in accordance with these. In this case, in particular, the light output is controlled by the LEDs 23 or by their groups, which are located within the entirety of the LEDs 23 of the light generators.

supply arrangement 21 of the lighting device 1 can be defined.

The control arrangement 10 is set up to process the received control signal, for example by means of a computing device such as a microprocessor. In this case, the control signal can be evaluated or interpreted by the control device 10 . This microprocessor-based evaluation or processing can, for example, use a DALI protocol

or a DMX protocol or a ZigBee protocol.

Alternatively, the use of a 0-10V protocol is conceivable, whereby when using

This protocol does not require a microprocessor-based evaluation.

The control arrangement 10 can be used to dim the light-generating arrangement 21, either in its entirety with all of the LEDs 23 arranged on the strip-shaped component 22, and/or individual LEDs 23 and/or groups of these, depending on the control signal. In the case of the DALI, DMX or ZigBee protocol, the dimming takes place electronically by the control arrangement 10 using a microprocessor provided on the printed circuit board 28 as the computing device. If the dimming is based on the 0-10V protocol, the dimming can be done without using a microprocessor

be led. The control arrangement 10 can be in addition to that described above

Dimming, or alternatively set up to be, one color and/or one

Color temperature of a light by the light generating arrangement 21 and / or

the individual LEDs 23 and / or emitted by groups of these, depending on the received control signal to adjust or change. In this variant, the control arrangement 10 is thus set up to evaluate or interpret an RGB control signal and/or a “tunable white” control signal, and the light-generating arrangement 21 and/or its LEDs23 individually or

to be controlled in groups accordingly.

For example, the light generating devices 23 are controlled by means of pulse width modulation (PWM), for example 48 volt PWM, 24 volt PWM or 12 volt PWM. For example, the conductors 45, 46 in FIG. 8 can be driven by means of 48V PWM, while the converter 78 transmits a load via the conductors 19a, b.

drive voltage of 48 volts.

FIG. 8 also illustrates a lighting arrangement 100 which includes the tubular lighting device 1 and a fastening device 55 . The fastener 55 includes a mounting portion 64, a cover portion 65, two clamp members 66 and two clamp members 67, and a mechanism 68 for each of the clamp members

66 to actuate the same.

The tubular lighting device 1 is fastened in the region of the end section 6 by means of the fastening device 55, for example on a wall, on a ceiling or on a floor of a room. Another fastening device, not shown in detail, can be used to fasten the second end section—if

handen - the lighting device 1, which is also not shown, are used.

In the exemplary embodiment shown, the 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, while at the same time the control arrangement 10 is also covered by the fastening device 55, in particular by the mounting part 64 and the cover part 65. The control assembly 10 is thus "hidden" in an aesthetic manner without the need for a separate housing for it or the attachment of the tubular light fixture

1 would be complicated. At the same time, the visible extension of the light

The lighting device 1 is supplied with electrical energy via the elongated end section 6 . The already mentioned external converter 78 shown in FIG. 8 is provided for this purpose. In addition, control signals are supplied to the lighting device 1 via the end section 6 . Fig. 8 shows schematically the coupling of the lighting device 1 mediated via the converter 78 to the power supply (conductors L, N) and with

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. For clamping the end section 6 in the opening 69, a clamping device is provided, comprising the two clamping elements 67 designed as clamping screws. On the rear side of the fastening device 55, see Fig. 6-7, the end section 6 can protrude somewhat from the mounting part 64, this part not being visible to the viewer after assembly is complete and the visible side of the fastening device 55

is turned.

To fasten the lighting device 1, 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 thus fixed to the mounting part 64.

The mounting part 64 is fastened to a further 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 clamping. For this purpose, an opening in the plate-shaped component

85 are formed, into which the fastening device 55 and the end section 6 accommodated therein are introduced 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. By moving the clamping elements 66 by means of the respective associated mechanism 68, the surfaces 71 can be moved relative to the overhang 70 and thus adjusted or adjusted in their position. For this purpose, the mechanism 68 can each have a screw element 72, by turning the clamping element

66 along the screw element 72 is adjustable.

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 . In this way, the lighting device 1 in the region of the end portion 6 on the wall or

Fixed to the ceiling or alternatively to a floor.

Furthermore, 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

can be carried out by clamping or in some other way.

It should also be mentioned that 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

screws is tightened. After fixing the end section 6 in it by clamping

men, and after the attachment to the plate-shaped component 85 described above, covered by the cover 65 in a pleasing manner.

The end section 6 is thus used in the tubular lighting device 1 both for fastening the lighting device 1 and for accommodating the control

arrangement 10. 2

The integration of the control arrangement 10 or the PCB 28 within the silicone tube 1 makes it easier to use different attachment options on the end section 6 . In particular, 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.). Furthermore, particularly when installing the lighting device 1, there is no need to consider a separate component, such as a housing of this type with the control arrangement 10 located therein, outside of the

Luminaire body are taken.

In this way, 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 assembled 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 emission section 3 and largely evenly

Rig emits light.

As described above, the 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, behind the plate-shaped

Element, such as the false ceiling, are arranged.

It should also be mentioned that the control arrangement 10 can, if necessary, but not necessarily

way, with additional functions that can be controlled via the control

tion of the LEDs 23 or the light-generating arrangement 21, equipped

can be.

As already mentioned, the lighting arrangement 100 can comprise a plurality of tubular lighting devices 1 which can be supplied jointly by the external converter 78 . Such a light-generating arrangement 100' is shown schematically in FIG. 9. The lighting devices 1 can be controlled individually, or, see FIG. 9, it can be provided that some or all of the plurality of tubular lighting devices 1 are assigned to a control group SG, such that the lighting devices 1 assigned to the control group SG can be controlled together. In such a control group SG, two or more tubular lighting devices 1, as described above, each with a light-generating arrangement 21 with a large number of LEDs 23, can be combined for the common purpose

Control analogous to that described above for the lighting device 1. Although the invention has been fully

constantly described, it is not limited to this, but in many different ways

and way modifiable.
