Light for lighting a workplace

Abstract

A luminaire (100), for example for illuminating a workplace, has a column-like base body (10) with first light-emitting means (30) designed to emit a first light, and at least one light-emitting module (50) with second light-emitting means (55, 56) designed to emit a second light separate from the first. The light-emitting module (50) can be detachably attached to the column-like base body (10) in different positions and / or orientations.

Description

[0001] The present invention relates to a luminaire designed, for example, to illuminate a workplace or work area. In particular, the luminaire can be intended to illuminate a home office workplace in a versatile manner.

[0002] The requirements for professional workplace lighting are defined by a variety of regulations and standards. These standards specify the brightness at which workplaces should be illuminated to enable efficient work, such as reading or editing documents. Furthermore, the light should be emitted in a specific manner to avoid distracting reflections, for example, on screen surfaces. All of these measures contribute to creating a work environment in which optimal conditions for efficient work exist, at least in terms of lighting conditions.

[0003] The standards and measures described above primarily relate to office lighting. However, more and more work is now being done from home offices, i.e., in private areas where appropriate implementation of the lighting standards is not possible. A large portion of home office work is performed on private PCs, especially laptops, placed at a table available at home that is usually used for other purposes, especially not office work. The lighting available at this location can therefore vary greatly depending on the current situation and is generally unlikely to meet the requirements for satisfactory workplace lighting.

[0004] However, inadequate lighting in a home office not only negatively impacts the legibility of documents and / or screens, but also impairs the well-being of the person working there. Furthermore, it should be taken into account that, due to increased home office work, more and more video conferences are being held, for which the camera of a laptop or the camera attached to a laptop or PC is used. Even in this situation, it is unlikely that the person participating in the video conference will be sufficiently illuminated to produce satisfactory images with the help of the camera. People often appear underexposed or with very uneven exposure, or in a color tone that is perceived as unpleasant or unhealthy, which can be due, for example, to the use of light sources with a color temperature that is particularly cold.

[0005] A luminaire with the features of the preamble of claim 1 is known from DE 20 2019 102 713 U1. This is an outdoor luminaire with a support tube extending in a longitudinal direction and a guide tube detachably attached to the support tube. The guide tube accommodates a reversibly replaceable flashlight as a lighting element.

[0006] Furthermore, in the prior art, DE 10 2018 122 361 A1 shows a modular luminaire system which comprises a luminaire base body and a luminaire support structure for fastening the luminaire base body, wherein the luminaire base body can be flexibly connected to the support structure via an adapter element.

[0007] Finally, US 2017 / 0211787 A1 shows a floor lamp in which several lamp heads can be flexibly attached to a vertical column.

[0008] The present invention is based on the task of providing a solution for the above-described situation of working from home, which easily creates the best possible lighting situation, facilitating work and promoting the well-being of the worker. In particular, the luminaire should offer the possibility of flexibly adapting the lighting situation to the current area of ​​use.

[0009] The object is achieved by a luminaire having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

[0010] The core idea of ​​the present invention is to provide a luminaire that can be used simply and flexibly to create optimized lighting conditions in spaces used, for example, for home office work. It is assumed that home office work primarily involves working on a screen - such as a laptop - or reading documents. In this case, the lighting directly in the work area must be such that sufficient brightness is available, for example, to read documents. At the same time, however, the area surrounding the workstation should also have a certain basic brightness. On the one hand, this serves to improve the overall working atmosphere in the area, and on the other hand, working on screens, for example, can be made more pleasant by reducing contrast.

[0011] The luminaire according to the invention therefore has a plurality of light-emitting means that fulfill the various lighting tasks mentioned and, moreover, can be easily adapted to the current situation. For this purpose, the luminaire according to the invention comprises a columnar base body containing first light-emitting means designed to emit a first light. Furthermore, at least one lighting module is provided with second light-emitting means designed to emit a second light separate from the first light, wherein the lighting module can be detachably attached to the columnar base body in different positions and / or orientations.While, for example, the first light from the first light-emitting means can be used to create background lighting to facilitate work, the second light-emitting means of the flexibly positionable lighting module can be used to specifically illuminate a specific area, for example, to facilitate reading documents or support work on a screen. The base body has connection means to supply the lighting module with power, which are accessible via a fold-out or swing-out compartment.

[0012] According to the present invention, a luminaire is proposed which is intended, for example, for illuminating a workplace or a work area and has the following: a columnar base body having first light emitting means configured to emit a first light, at least one lighting module having second light emitting means configured to emit a second light separate from the first light, wherein the lighting module is detachably attachable to the columnar base body in different positions and / or orientations, wherein the base body has connection means for supplying the lighting module with energy, and wherein the connection means are accessible via a fold-out or swing-out compartment which is formed on the base body.

[0013] The lighting module containing the second light-emitting means therefore serves, in particular, to flexibly adapt the total light emitted by the luminaire to the respective situation. Accordingly, extremely simple and flexible positioning of the second lighting module is desirable, in particular to be able to easily influence the direction of the second light emission. For this purpose, it can preferably be provided that the lighting module can be attached to the outside of the base body by means of magnetic force. This represents a particularly simple procedure for adapting the light output of the luminaire quickly and efficiently.

[0014] The lighting module is preferably designed to emit the second light over a surface area, in particular in a glare-free manner. While the light from the first light sources primarily serves to provide a certain background illumination, the lighting module is intended to specifically illuminate the work area or, in the case of a video conference mentioned above, a person using the work area. In this case, it is desirable that no glare effects and / or excessive local brightness occur, which is why the aforementioned homogeneous, flat, glare-free light emission is preferable.

[0015] The flexibility of positioning the lighting module can further be increased according to an advantageous development of the invention in that the lighting module has an internal energy storage source, in particular an accumulator or the like.

[0016] According to the invention, as already mentioned, the base body of the light has connection means that allow the lighting module to be supplied with energy when needed. In the case of the aforementioned rechargeable battery, this energy supply via the base part can only be temporary, in order to charge the internal energy storage source of the lighting module. Alternatively, however, it would also be conceivable for the lighting module to be supplied with energy permanently from the base body, i.e., particularly during operation. The connection means can preferably include a USB interface.

[0017] According to another advantageous development of the invention, the base body can further comprise a receiving area for storing the lighting module when the module is inactive. This means that the module can be easily laid down and safely stored when not in use or when the lamp is inactive. Preferably, the receiving area is designed such that the lighting module accommodated therein continuously and flushly extends an outer surface of the base body.

[0018] As already mentioned, the first light-emitting means primarily serve to provide background lighting, which improves the overall working atmosphere in the room. Accordingly, these light-emitting means, which cannot be changed with regard to their light emission direction, are preferably designed such that the first light is emitted either toward a top or toward a rear side for indirect illumination.

[0019] In principle, the first and / or second light-emitting means are preferably designed to emit the light they emit with a variable intensity and / or a variable color or color temperature. This further increases the possibilities for adapting the overall lighting situation in the area surrounding the luminaire. It can be provided that the light output of the various light-emitting means can be adjusted completely independently of one another. However, coordinated control or automated, for example, time-dependent control of at least some of the light-emitting means would also be conceivable.

[0020] For example, the luminaire can be designed to be connected to a PC or laptop. This connection can be used to supply power to the luminaire, but it would also be conceivable to use this connection to control the light emitting devices via a corresponding PC application program.

[0021] As an alternative to wired control of the luminaire, it would also be conceivable to equip it with means for wireless communication with an external control device. This external control device could then be, for example, a suitable mobile phone or another device designed to enable wireless communication. Of course, it would also be conceivable, alternatively or in addition, to provide control elements for manual control of the luminaire directly on the luminaire or the lighting module.

[0022] Until now, it was assumed that the luminaire had a lighting module with second light-emitting means, which could be used to realize targeted so-called task lighting in addition to the background lighting provided by the first light-emitting means. Of course, it would also be conceivable to provide several corresponding lighting modules, each designed in a corresponding manner, but each arranged independently of one another on the base body and adjustable in terms of its light output. This obviously further increases the possibilities for adjusting the light output.

[0023] The luminaire is preferably designed as a floor-standing luminaire, although in the case of illuminating a home office workstation, it can also be designed as a table-top floor-standing luminaire. In principle, however, the use of the luminaire according to the invention is not limited to the illumination of home office workstations; rather, the concept could also be used in a comparable manner for luminaires for room lighting. In this case, too, the first light-emitting means initially serve to provide a certain background lighting, with the light from the at least one lighting module then being used to specifically illuminate a specific area in the vicinity of the luminaire in the desired manner.

[0024] The invention will be explained in more detail below with reference to the accompanying drawings. They show: Figure 1 shows a first embodiment of a lamp according to the invention, where only the base body without the lighting module is shown; Figure 2 shows the lamp according to Figure 1 with two lighting modules arranged on the base body; Figure 3 shows a lighting module of the lamp according to the invention in an enlarged view; Figure 4 shows an exploded view of the lighting module according to Figure 3 ; Figures 5 to 7 show a first possibility for mounting the lighting modules on the base body; Figures 8 to 10 show views of a second variant for mounting the lighting modules on the base body.

[0025] As already mentioned, the luminaire according to the invention is intended to largely solve the problems of efficient lighting associated with the use of, for example, a laptop during home office activities, even from a professional perspective. First, a pleasant working atmosphere is created by an initial light emission. If desired, circadian light can be emitted within a broad color temperature spectrum to achieve a high level of well-being, enabling fatigue-free working and a high level of concentration. Furthermore, the luminaire according to the invention can efficiently eliminate the problem of luminance differences between a monitor and the surroundings, and the associated glare. This is achieved, as explained below, by the ability to flexibly combine and adjust different types of light emission.

[0026] The luminaire proposed according to the invention is initially basically in the Figures 1 and 2 and generally designated by reference numeral 100. In the illustrated embodiment, it is a multifunctional luminaire designed as a floor lamp, which can be configured, for example, as a table lamp and then positioned in the area of ​​the work surface of the home office workstation during use. As already mentioned, however, the luminaire 100 according to the invention can be used extremely flexibly and does not necessarily have to serve to illuminate a workplace. Accordingly, it would also be possible to use the luminaire as a larger floor lamp for room lighting or to implement it in the form of a suspended luminaire.

[0027] The basic structure of the luminaire 100 according to the invention initially forms a vertical pillar, which forms a columnar base body 10. In the illustrated embodiment, the base body 10 is formed by two elongated, C-shaped profile parts 11, which are vertically aligned and face one another and thus together enclose a vertically extending, elongated receiving space in which the actual electronics of the luminaire 100 and the first light-emitting means described in more detail below are arranged. At its lower end, the base body 10 is arranged on a horizontally aligned base part 20, which serves to stably support the luminaire 100 on a standing surface. In the illustrated embodiment, the base part 20 is also formed by a C-shaped profile part, which - as described in more detail below - can be used to support the additional lighting modules.

[0028] As already mentioned, the luminaire 100 according to the invention is intended to provide different types of light emission in order to fulfill various tasks regarding the illumination of a workplace or work area. Accordingly, the luminaire 100 has several different light emission means, each of which fulfills different functions and will be explained in more detail below.

[0029] Thus, first light emitting means 30 are provided on the base body 10 itself. In particular, these first light emitting means 30 are as shown in Figure 1visibly arranged at the upper end of the base body 10 and designed such that the first light emitted by these light emitting means 30 is directed upwards. The light emitted by these first light emitting means 30 serves, in particular, to illuminate a ceiling area of ​​a room located above the luminaire 100 or the workstation in the sense of indirect lighting. A so-called "cave effect," which can occur, for example, in the case of insufficient ambient brightness and which makes the working situation more difficult, can be eliminated in this way. These first light emitting means 30 are preferably LED lamps, to which suitable optics may be assigned in order to avoid point-like light emission with strong luminance differences.

[0030] The light emitted by these first light-emitting means 30 initially provides a basic brightness in the room or in the area where the luminaire 100 is positioned, which improves the overall atmosphere. In this context, it would also be conceivable to position the first light-emitting means 30 on the base body 10 such that they emit light towards a rear side, i.e. away from the actual work area, in order to, for example, illuminate a wall located at the rear of the workstation. In this case, too, a certain basic brightness is created, which, as already mentioned, improves the basic lighting situation and creates a pleasant working atmosphere. This light emission towards the rear can, of course, also be realized by the lighting modules to be described in more detail below.In the case of the illustrated embodiment of the base body as a vertical column, it is particularly suitable to use the first light emitting means 30 as shown for emitting light towards the upper side.

[0031] The direction of light emission cannot be changed with the first light emission means 30. These are permanently attached to the columnar base body 10. However, since these first light emission means 30 are only intended to provide a certain basic illumination, flexible directional adjustment of the light emission is less important here. This does not apply, however, to those light emission means intended for so-called task lighting, which are intended to illuminate specific areas in a very specific manner.

[0032] These tasks are achieved according to the invention by additional lighting modules 50, which can be arranged and aligned in a flexible manner on the base body 10. In Figure 2 For this purpose, two lighting modules, designated by the reference numeral 50, are shown, each of which is identical in design and can be arranged as desired on the outside of the base body 10. Of course, the number of lighting modules 50 used can vary depending on the manner in which overall lighting is to be provided. According to the invention, at least one lighting module 50 is provided; however, the use of at least two modules 50 has proven particularly advantageous, since in this case, almost all lighting tasks can be fulfilled in the sense of comfortable workplace lighting.

[0033] As already mentioned, a special feature of these lighting modules 50 is that they can be arranged extremely flexibly on the base body 10 of the luminaire 100 with regard to their position and orientation. A particularly simple variant for enabling this flexible arrangement consists in attaching the lighting modules 50 to the outside of the base body 10 by means of magnetic force. For this purpose, the lighting modules 50 have corresponding magnets that enable easy attachment to the base body 10, which is preferably made of ferromagnetic metal. Not only can the height of the attachment to the base body 10 for the lighting modules 50 be selected, but there are also no restrictions regarding the sides of the base body 10 to which the modules 50 are attached, nor their orientation.As an alternative to the magnetic force mentioned, other fastening mechanisms would of course also be conceivable, although the solution described here is particularly easy to implement and at the same time ensures the greatest possible flexibility.

[0034] The design of a single lighting module 50 is shown in the Figures 3 and 4 This is a plate- or disc-like component with approximately square dimensions, with a larger surface 52 provided on a flat side of the housing 51, over which the most homogeneous, glare-free light emission is achieved. The previously mentioned magnets 53, which enable detachable attachment to the base body 10 of the luminaire 100, are located on a narrow side of the housing 51.

[0035] Figure 4shows the lighting module 50 in an exploded view, wherein it can be seen that LEDs 55, preferably micro-LEDs, are provided within the flat housing 51, arranged in a matrix-like manner on a bottom surface, which LEDs enable a planar light emission over a larger area. Since, as already mentioned, the light emitted by the LEDs 55 should be emitted as homogeneously as possible, in particular glare-free, an appropriately designed optical system 56 is arranged upstream of the LEDs 50, which has suitable light influencing means by which a uniform light mixing and homogeneous light emission is achieved. These can be corresponding light-refracting structures in the form of prisms and / or lenses. Alternatively or additionally, corresponding scattering films or other scattering elements can also be provided.It is essential that the optical system 56 ensures that the light emitted by the essentially point-shaped individual LEDs 55 is emitted homogeneously across the entire light-emitting surface 52, so that this is perceived as a uniformly illuminated surface. By using a larger surface for light emission, the risk of glare is also avoided.

[0036] The optical system 56 is held to the housing 51 by means of a corresponding cover 57, thereby enclosing an interior of the lighting module 50, in which, in addition to the LEDs 55, means for operating the LEDs 55 are also arranged. First of all, corresponding electronic components 58 should be mentioned here, which form a driver via which a suitable operating voltage is made available to the LEDs 55. Another essential element, however, is also corresponding energy storage means in the form of accumulators 59, via which a power supply to the components responsible for emitting light is ensured. The lighting modules 50 can thus be arranged and operated on the base body 10 completely independently, i.e., without an external power supply, at least for a certain period of time. However, it would also be conceivable to permanently supply the lighting modules 50 with external power from the base body 10.

[0037] In principle, the lighting modules 50 can be implemented in a variety of ways with regard to the components responsible for light emission. For example, as an alternative to the illustrated matrix-like arrangement of LEDs 55 on so-called backlight boards, which are then preceded by optical elements in the form of microprism optics, films, diffusers, and the like in order to convert the light from the essentially point-like LED light sources into a light emitted homogeneously over a large area, the use of known fiber optic technology would also be conceivable. In this case, the light from preferably several LEDs is coupled into the end face of a plate-shaped light guide, distributed across it by means of multiple reflections, and then coupled out on a flat side. Furthermore, the use of so-called OLEDs (organic LEDs) would also be conceivable as an alternative.These are light sources that can be realized with a larger surface area compared to semiconductor-based LEDs and also offer a simple way of controlling the color temperature, so that a more homogeneous light output can be achieved and the effort required to evenly distribute the emitted light is reduced.

[0038] In the following, it will be explained in more detail to what extent the various functions of efficient workplace lighting can be fulfilled with the aid of the lighting modules 50 according to the invention.

[0039] For example, it is possible to arrange at least one of the lighting modules 50 on the base body 10 of the lamp 100 in such a way that the light emitted over a wide area is directed toward a front side in order to directly illuminate a workstation. In particular, a work area on which a laptop is positioned, as well as the area of ​​a table surface surrounding the laptop, could be illuminated. Documents placed in front of or next to the laptop can then be read more easily due to this lighting, in particular when the ambient lighting or the basic lighting of the first lighting means 30 does not provide sufficient light for this purpose.

[0040] A further effect of the light emitted in this way can, however, also be to illuminate the person using the workstation with a certain brightness. This is particularly advantageous if, for example, a laptop located at the workstation is used to conduct video conferences and a camera image of the person is to be captured for this purpose. Often, the lighting provided at a home office workstation is not sufficient for optimal video recording or the color temperature of the available light has a negative impact on the video recording. This problem can also be efficiently solved with the help of the lighting module 50, since it is now ensured that optimal image recording can be guaranteed thanks to this targeted additional lighting.Of course, this effect can also be realized if necessary with the help of a further lighting module 50, which in turn is arranged in the corresponding manner on the base body 10.

[0041] The light emitted by the second light-emitting means of the light modules 50 also helps to avoid strong light contrasts. These could arise, in particular, from the monitor luminance in a dark environment and make working significantly more difficult, as frequent and intensive adaptation of the human eye is required.

[0042] Finally, it would also be conceivable to arrange a lighting module 50 on the base body 10 in such a way that it emits light specifically toward a rear side opposite the workstation. In this case, the light emitted by the additional light-emitting means can then illuminate an area behind the workstation, for example, a wall behind it. This light emission then leads to the correspondingly illuminated spatial areas having a contrast-reducing effect on the luminance of a laptop monitor. This also contributes overall to a better appearance of the entire room and improves the working atmosphere.

[0043] Preferably, it is possible to individually adjust the light emitted by the respective light emitting means 30 or lighting modules 50 in terms of its intensity and / or color or color temperature. In this case, it is possible to adapt the various light components to one's own preferences. For example, it would be conceivable to select a somewhat lower color temperature of the light emitted by a lighting module 50 towards the front in order to make the illumination of a user's face, for example, appear warmer and thus more pleasant. For indirect lighting towards the top using the first lighting means 10 or towards the rear using another lighting module 50, however, the light can also have a somewhat cooler color tone - possibly depending on the time of day - in order to develop a stimulating effect.Overall, the positioning of the 50 lighting modules and the appropriate control of the various light emitting devices can create an optimal lighting situation for a home office workstation. Due to the flexibility of the arrangement and adjustment of the light output, an optimal lighting situation can be created for a wide variety of situations.

[0044] The primary function of the base body 10 is, as explained, to emit light using the first light emitting means 30 and to enable the most flexible arrangement possible of the further light modules 50 or of the at least one further light module 50. However, the base body 10 can also be used to supply energy to the light modules 50 and to enable their storage during periods of non-use. Various variants of this will be described below with reference to the Figures 5 to 10 be explained.

[0045] The Figures 5 to 7 show a first variant, whereby the base body 10 including the lamp base 20 is basically designed in the same way as in the Figures 1 and 2 A first special feature is that, as shown in particular in Figure 6 It can be seen that the area 21 enclosed by the C-shaped profile part of the lamp base 20 can also be used to store two lighting modules 50. These are adapted to the shape of the lamp base 20 in terms of their dimensions, so that they can be arranged as shown in Figure 5can be seen inserted into the corresponding area 21 at the front and positioned there in the event of non-use. The lighting modules 50 are then stored safely and reliably and can be removed from the corresponding receiving area 21 at any time if necessary. Webs 22 running vertically in this area 21 serve as a corresponding rear stop, so that the lighting modules 50 are not pushed too far into the receiving area 21 and can be easily removed again at any time.

[0046] Another special feature of the Figures 5 to 7 The variant shown is that, as in the Figures 5 and 6shown, a fold-out or pivoting compartment 15 is provided on the base body 10. In the unfolded state, for example, corresponding connection options for the lamp 100 can be provided, through which, for example, a cable connection can be established between the base body 10 and the lighting modules 50. Via such a connection, the lighting modules 50 can then be continuously supplied with energy during use. Alternatively, however, the connection can also be used to temporarily enable the internal batteries 59 of the lighting modules 50 to be charged. The connection can in particular comprise a USB interface, preferably an interface corresponding to the USB-C standard. Furthermore, the compartment 15 could also be used to store, for example, a remote control, with the aid of which the lamp 100 can be wirelessly controlled and its light output can be adjusted.

[0047] An alternative way of storing and supplying energy to the light modules 50 is described in the Figures 8 to 10 Here, corresponding receiving areas 17 are formed on the base body 10 itself, which are formed by recesses in the base body 10 and into which the lighting modules 50 can be inserted or pushed for storage when they are not in use. Preferably, the shape of a receiving area 17 corresponds to the outer contour of a lighting module 50, so that in the received state, it continues the surface of the base body 10 flush, as in particular Figure 9 shows.

[0048] In the base areas of the receiving areas 17, connections 18a, e.g., in the form of USB ports, can be provided, via which, as described above, the lighting modules 50 can be supplied with power or their charging can be enabled. Furthermore, the base areas can also be used to store a connecting cable 18b, which enables the connection to the lighting modules 50. If necessary, this connecting cable 18b could also be permanently connected to the light 100 on the light side.

[0049] As can also be seen from the illustrations, an additional receiving area 19 for an external accumulator 60 can also be provided on the base body 10, via which the lighting modules 50 can then be easily charged.

[0050] As an alternative to the connection shown via a cable 18b, it would also be possible to design the receiving areas 17, 19 for the lighting modules 50 and / or, if applicable, for the external accumulator 60 in such a way that, when the respective element 50, 60 is inserted, it is automatically supplied with energy and charged accordingly.

[0051] The base body 10 of the luminaire 100 itself then has corresponding connection means (not shown) for an external power supply. This can be a conventional power supply cable, which is then connected to a standard connection socket for a mains supply voltage. A connection to a PC or laptop, again preferably via a USB cable, is also conceivable. In this case, the luminaire 100 would not require its own power supply, but could be powered directly by the work device at the home office workstation.

[0052] Coupling the luminaire 100 with a PC or laptop could also be used for convenient control of the luminaire 100. For this purpose, a special user interface could be provided on the PC, for example, with which the intensity of the various light emitting devices, as well as the color or color temperature of the emitted light, can be conveniently adjusted. Automated or semi-automated control of the light emitting devices would also be conceivable, with the light output then being adjusted, for example, based on the use of the PC and / or the current time.

[0053] However, a comparable user interface for controlling the luminaire 100 and for adjusting the various lighting parameters could also be provided using a corresponding app on a mobile device, such as a mobile phone or tablet. This app is then wirelessly connected (e.g., via Bluetooth) to the luminaire 100 via a corresponding communication connection in order to be able to control it.

[0054] Finally, it would of course also be possible, alternatively or in addition to this, to attach corresponding control elements to the luminaire 100 itself, which would enable manual adjustment of the light output.

[0055] A further advantageous development of the invention, not shown in the figures, can also consist in providing the lamp 100, i.e. the base body 10 or at least one of the lighting modules 50, with a camera.

[0056] On the one hand, this camera could be used as a sensor to detect the lighting situation, with the light output of at least some of the various light emitting devices then being adjusted accordingly. This could then particularly affect the control of the light used to illuminate a user. Depending on the image captured by the camera, the light intensity and color temperature are adjusted in such a way that the user of the workstation is illuminated as optimally as possible for a video conference.

[0057] Secondly, this camera could also be used to conduct a video conference, for example, replacing the possibly lower-quality camera on the user's laptop. The image captured by the camera of the light 100 is then not only used to optimize the lighting settings, but also simultaneously provides the video image used for conducting a video conference. For this purpose, the camera could be connected to the laptop wirelessly or via a cable (e.g., a USB cable). In this case, the camera could, of course, also have a corresponding microphone.

[0058] Overall, the present invention provides a novel luminaire that solves a wide range of tasks in modern lighting technology with regard to the illumination of workplaces, particularly in home offices, in a simple and extremely flexible manner. The luminaire is characterized by its extremely flexible application possibilities, which allow for suitable adjustment of the light output at any time to ultimately achieve optimal lighting.
