Description

[0001] The present invention relates to a luminaire intended for illuminating a workplace, in particular for illuminating a home office workplace.

[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, at least in terms of lighting conditions, optimal conditions for efficient work exist.

[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] 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 the increased number of people working from home, more and more video conferences are being held, for which the camera on 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 lit to produce satisfactory images with 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 attributed, for example, to the use of light sources with a color temperature that is particularly cold.

[0005] WO 2007 / 026285 A1 discloses a display system comprising an LCD display unit and a diffuser system for emitting ambient light. The diffuser system comprises a plate that is substantially adjacent to the LCD display unit and extends away from the LCD display unit. The plate is configured to couple in light emitted by LEDs, redirect it, and couple it out as ambient light via interruptions in the plate.

[0006] DE 200 21 973 U1 discloses a picture frame-like night lamp, which essentially consists of a translucent front plate, a frame-shaped light guide plate, a circuit board and a front and rear cover, wherein the circuit board can be connected to a power source in order to radiate light onto the light guide plate, which reflects the light outwards, thereby illuminating the picture enclosed in the front cover, thus creating a picture frame-like night lamp.

[0007] CN 104633585 A discloses a solar photo frame desk lamp comprising a base and a photo frame body, wherein a number of LEDs are arranged around the photo frame area and a solar panel is arranged on the back of the photo frame body, which is connected to the photo frame body.

[0008] The present invention is based on the task of offering a solution for the home office work situation described above, with the help of which the best possible lighting situation can be created in a simple way, which makes working easier and promotes the well-being of the working person.

[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 the space used for home office work. It is assumed that home office work is predominantly carried out using a laptop or a comparable portable work device, whereby the luminaire according to the invention is then initially designed to illuminate the area surrounding the laptop and a person using the work device with as little glare as possible. For this purpose, the luminaire has a plate-like lighting fixture as its central element, which can be positioned essentially vertically using suitable fastening means and can be arranged, in particular, behind the laptop display.On a front side of the plate-like lighting fixture, which is formed by a flat side of the lighting fixture, first light emitting means are then provided, which emit light over a frame-like surface area surrounding the screen of the laptop.

[0011] According to the invention, a luminaire for illuminating workplaces is proposed, which comprises: a plate-like lighting body with fastening means arranged thereon, which are designed to arrange or hold the lighting body in a substantially vertically aligned manner, as well as first light emitting means arranged on a front side, which is formed by a flat side of the lighting body, which are designed to emit light over a frame-like surface area, in particular over a U- or C-shaped surface area.

[0012] The light according to the invention can therefore be flexibly positioned on the back of a laptop and is then designed in such a way that it frames the laptop screen and emits light onto the area in front of the laptop as well as onto a person using the laptop. On the one hand, this means that documents placed in front of the laptop, for example, can be read and, if necessary, edited more easily, as they are now illuminated regardless of external lighting conditions. On the other hand, the legibility of the device's display is also improved, as the non-glare, frame-like light emission reduces the contrast compared to the surroundings, thus making it easier for the viewer to adapt to the light. Finally, the light emission according to the invention, with the aid of the first light emission means, also contributes to illuminating the person themselves, which leads to a significantly improved appearance with regard to the video conferences mentioned above.This significantly improves the lighting situation for home office work on a laptop or similar device.

[0013] In this case, it can preferably be provided that the inclination of the lighting fixture is adjustable, for example, relative to a supporting surface. Just as the inclination of a laptop display can usually be adjusted, the inclination of the lighting fixture can also be adjusted accordingly, ensuring that the screen fits optimally into the frame-like light emitted by the first light source.

[0014] The first light sources are preferably designed to emit light with minimal glare. This is particularly advantageous because, as already explained, the light emitted by the first light emitting means is also directed directly at the user of the luminaire, and annoying glare should, of course, be avoided.

[0015] According to a preferred development of the invention, the flexibility of the first light-emitting means can be further increased by dividing the frame-like surface area into at least two - preferably mutually symmetrical - sub-areas, wherein the light can be emitted via each of the sub-areas independently of one another. This makes it possible, for example, to take into account the fact that natural lighting often occurs very one-sidedly at workplaces located near windows. This can then be compensated for by the corresponding sub-area of ​​the frame-like surface area emitting only light with reduced brightness or no light at all, while the other sub-area, from whose direction no natural light is incident, emits light intensified.This also helps, especially when conducting video conferences, to ensure that a participant's face is not only illuminated from one side, but instead is optimally illuminated overall.

[0016] With the help of the frame-like first light emission, the area used for actual work, as well as the person working, are optimally illuminated. According to an advantageous development, however, the luminaire according to the invention can also be used to improve the overall lighting situation in the room.

[0017] For this purpose, according to the invention, further light emitting means are provided on a rear side of the lighting fixture opposite the front side, said light emitting means being designed to emit light in an opposite direction. With the help of these further light emitting means, which preferably emit light over a large area and in particular also diffusely towards the rear, the area of ​​a room behind a workstation or a wall behind the workstation can then be illuminated, for example. This additionally contributes to improving the working situation, as the laptop display and the frame-like lighting are no longer perceived as the only large-area light source in the room, but rather the room as a whole has a certain basic brightness. This leads to a further reduction in excessive brightness contrasts, which would otherwise have an unpleasant effect on the working situation.

[0018] Furthermore, in addition to the additional light-emitting means, further light-emitting means are provided on a narrow side connecting the front and rear of the lighting fixture. These then serve in particular to emit light toward the top and, for example, to illuminate the ceiling above a workstation in a room as indirect lighting. In a similar way, this makes the overall lighting situation in a room more pleasant, which contributes to improving the user's well-being.

[0019] Preferably, all of the light emitting devices provided by the luminaire are independently adjustable, particularly with regard to their intensity and color coordinates or color temperature. Adjusting the color temperature, particularly of the light used for backlighting and indirect lighting, can serve to further improve well-being through the use of so-called circadian stimulating light. Depending on the time of day or the user's preferences, a color temperature for the light can then be selected that has a more stimulating effect on the user, thus sharpening concentration while working. At certain times, however, a slightly warmer color tone could be selected to create a more pleasant atmosphere.Adjusting the color temperature of the light emitted to the front is also beneficial in order to create optimal illumination for a camera shot from the user's perspective.

[0020] A further possibility for increasing the flexibility of the light emission can be to adapt the thickness of the frame-like region over which the light is emitted by the first light-emitting means to a certain extent. This could create the possibility of adapting the frame-like light emission as precisely as possible to the dimensions of a laptop located in front of the light. According to an advantageous development, the light can further be designed such that it can be coupled to a PC, wherein the coupling can be used in particular for the power supply and / or also for the control of the light. For example, a connection to a laptop via a corresponding USB port would be conceivable, thus making the use of a separate power supply unnecessary.A suitably designed user interface could also allow for particularly convenient or partially automated adjustment of the light output of the various light emitting devices. Of course, it would also be conceivable to control the luminaire according to the invention wirelessly via a suitable control device—e.g., a mobile phone—or with the aid of corresponding control elements located directly on the luminaire.

[0021] According to the invention, a method for illuminating a workstation comprising a laptop positioned on a surface is further proposed, the method comprising the following steps: Arranging the lamp according to the invention on the support surface at the rear of the laptop and activating the first light emitting means to illuminate the workstation.

[0022] In this case, it is preferable to provide for an adjustment of the intensity and / or color or color temperature of the light emitted by the first light emitting means, taking into account an image or video recording made by a camera of the laptop.

[0023] Overall, this provides a luminaire that can be used to significantly optimize the lighting situation at home office workplaces in a simple but extremely efficient way.

[0024] The invention will be explained in more detail below with reference to the accompanying drawings. They show: Figures 1 and 2 Views of a preferred embodiment of a luminaire according to the invention; Figures 3a and 3b Views to illustrate a first lighting function of the luminaire according to the invention; Figures 4a and 4b Representations of a preferred variant for the realization of the first lighting function; Figures 5a and 5bViews illustrating a second lighting function of the luminaire according to the invention; Figures 6a and 6b Views illustrating a third lighting function of the luminaire according to the invention; Figures 7a and 7b Views of a combined light emission of all light emission means of the luminaire according to the invention; Figure 8 a diagram for adjusting the inclination of the lamp; Figure 9 the possibility of easily transporting the lamp according to the invention; Figure 10 a preferred variant for coupling the luminaire according to the invention with an external power supply unit; and Figure 11 a preferred possibility of controlling the luminaire according to the invention.

[0025] The luminaire according to the invention is intended to largely solve the problems of efficient lighting associated with laptop use during home office activities, even from a professional perspective. The problem of luminance differences between the monitor and the surroundings, and the associated glare, can be efficiently eliminated with the help of the luminaire according to the invention. In addition, if desired, circadian-effective light can be emitted within a wide color temperature spectrum to achieve a high level of well-being, enabling fatigue-free work and a high level of concentration.

[0026] The lamp proposed according to the invention is initially in the Figures 1 and 2and generally provided with the reference numeral 100. It is a flat, portable multifunctional lamp which, during later use, is intended to be positioned in particular behind the unfolded screen area of ​​a laptop. The lamp 100 accordingly initially has, as its central element, a plate-like lighting fixture 10 which forms the lamp housing and contains all components for generating and emitting light. A C-shaped bracket 20 is attached to two long sides 15 and 16 of the lighting fixture 10, which bracket enables the lamp 100 to be placed on a substantially horizontal work surface, on which the laptop is then also positioned, for example on a table top. A secure stand for the lamp 100 is made possible on the one hand by the cross-connecting leg 21 of the bracket 20, with the lamp 100 also resting on the underside 14 of the lighting fixture 10 for further support.Because the support bracket 20 can be pivoted about its two suspension points 22 and thus about an axis running parallel to the underside 14 of the lighting fixture 10, the inclination of the lighting fixture 10 relative to the surface on which the light 100 rests can be adjusted, in particular to the inclination of the laptop screen located in front of it.

[0027] The luminaire 100 according to the invention has a plurality of light-emitting means to fulfill various lighting tasks. Firstly, the first light-emitting means 30 are arranged on a front side 11 of the lighting body 10 and emit light via a U-shaped, downwardly open, frame-like surface area 35. As will be explained in more detail with reference to the following figures, this frames the screen area of ​​a laptop and emits light onto the laptop or the area in front of the laptop, on the one hand to illuminate the corresponding work surface, and on the other hand to illuminate a person using the laptop. The precise design and function of these first 30 light-emitting means will be explained in more detail below.

[0028] First, the additional light-emitting means of the luminaire 100 according to the invention will be briefly mentioned. Firstly, second light-emitting means 40 are provided on the rear side 12 of the lighting fixture 10, which is opposite the front side 11 and now emits light toward the rear side over a larger area 45. Secondly, third light-emitting means 50 are provided on the upper side 13, which connects the front side 11 and the rear side 12 of the lighting fixture 10, and whose light is primarily directed upwards. The design and function of these additional light-emitting means 40 and 50 will also be explained in more detail below.

[0029] Ultimately, the luminaire 100 according to the invention in the illustrated, particularly preferred embodiment comprises three different light emitting means 30, 40 and 50, each of which emits light in a different manner and thereby fulfills different lighting tasks. These lighting functions will now be described below with reference to the Figures 3 - 7 be explained in more detail.

[0030] The Figures 3a and 3b illustrate the light emission A by the first light emission means 30, which are arranged on the front side 11 of the lighting fixture 10. Shown in Figure 3a the situation of using the lamp 100 at a workstation 200, which may be formed, for example, by a simple table, on the surface of which a laptop 250 used for work is placed, on the back of which the lamp 100 according to the invention is arranged. Furthermore, in Figure 3aa person using the workstation 260 is shown.

[0031] As is now the case in particular with the representation of Figure 3a can be removed, the first light-emitting means 30 are provided to emit light towards the front via the frame-like surface area 35 in such a way that the workstation 200 on which the laptop 250 is positioned, i.e. in particular the area of ​​the table surface 210 surrounding the laptop 250, is illuminated. Documents placed in front of or next to the laptop 250 can be read more easily due to this lighting, in particular even if the ambient lighting does not provide sufficient light for this purpose.

[0032] A further effect of the light A emitted by the first light emitting means 30, however, is that the person 260 themselves is illuminated with a certain brightness. This is particularly advantageous when the laptop 250 is used to conduct video conferences and a camera image of the person 260 using the laptop 250 is to be captured for this purpose. Often, the lighting provided at a home office workstation is insufficient for optimal video recording, or the color temperature of the available light has a negative impact on the video recording. This problem is also efficiently solved with the help of the first light emitting means 30, since it is now ensured that optimal image recording can be guaranteed due to the appropriate additional lighting.

[0033] Finally, the light A emitted by the first light-emitting means 30 also helps avoid strong light contrasts. These could arise, particularly due to the monitor's luminance in a dark environment, and could significantly complicate working, as frequent and intensive adaptation of the human eye is required. By creating a luminous area surrounding the laptop screen 255, this problem is also reduced, thus creating a pleasant working atmosphere.

[0034] Ideally, the frame-like light-emitting area 35 of the first light-emitting means 30 is designed such that it borders as closely as possible to the outer perimeter of the laptop screen 255, but at least is not covered by it. The light-emitting area 35 should therefore be dimensioned such that a screen 255 of a standard size (with a size of 16 inches, for example, representing a reasonable upper limit) fits into the area framed by the downwardly oriented "C." For smaller screen sizes, the distance between the screen 255 and the light-emitting area 35 would then increase. A further development of the luminaire 100 will be explained later, which allows for adjustment of the light-emitting area 35 within certain limits.

[0035] Correspond to the representation of Figure 3bThus, the first light sources 30 emit light A toward the front. Since this light is directed directly at the user 260, it must be ensured that glare is avoided. In particular, glare-free light emission is sought, which is made possible by using the largest possible light emission area 35 and thus rather lower luminance levels, whereby the light should be emitted as homogeneously as possible across this area 35.

[0036] In principle, the first light-emitting means 30 can be implemented in a variety of ways. For example, a corresponding matrix-like arrangement of LEDs on so-called backlight boards, preferably of micro-LEDs, would be conceivable. Optical elements in the form of microprism optics, films, diffusers, and the like are then arranged in front of these to convert the light from the essentially point-like LED light sources into a light emitted homogeneously over a large area.

[0037] Alternatively, the use of so-called OLEDs (organic LEDs) would also be conceivable. These are light sources that can be realized with a larger surface area than semiconductor-based LEDs and also offer easy color temperature control, thus fundamentally achieving more homogeneous light output and reducing the effort required to evenly distribute the emitted light.

[0038] A preferred variant for implementing the first light emission means 30, however, consists in forming the frame-like light emission region 35 by appropriately shaped flat light guides into which light is coupled via narrow sides and evenly distributed by means of multiple reflections. In a known manner, appropriate light extraction structures, e.g. in the form of microprisms, can then achieve even light extraction over the entire region 35, so that completely homogeneous light emission is achieved over the U-shaped region. The implementation of the first light emission means 30 using the light guide technology just explained also has the advantage that in this case the lighting means can be realized with a very small thickness, which has an advantageous effect on the dimensions, in particular the thickness of the lighting fixture 10.

[0039] In principle, it would also be conceivable to use the aforementioned technologies in a mixed manner to achieve light emission.

[0040] An advantageous variant for the realization of the first light emitting means 30 is shown in the Figures 4a and 4b shown.

[0041] The advantageous further development here is that the first light emitting means 30 are divided, on the one hand, into a first part 30a located on the left side of the front side 11 and, on the other hand, into a second part 30b located on the right side. Both parts 30a, 30b can now be activated separately for light emission or their intensity can be adjusted, which has the result that, as shown by the two extreme situations of the Figures 4a and 4b is recognizable, then only the corresponding half of the work surface 210 and also the person 260 who is in front of the laptop 250 is only illuminated from the corresponding direction.

[0042] This partial use of the first light emitting means 30 may be particularly desirable if the natural lighting situation of the workstation 200 includes one-sided natural lighting. This may be the case, for example, if the workstation 200 is located laterally near a window through which natural daylight enters. Figure 4a In the situation shown, it is assumed that there is a window or other light source to the right of the workstation 200, while the opposite left side of the room is rather dark. In this case, it is advantageous if, in order to compensate for the natural light incidence, only the left part of the room is additionally illuminated by means of the first light emitting means 30, i.e., primarily the part 30a of the light emitting means 30 is activated. In the opposite case of Figure 4b however, only the second part 30b of the light emitting means 30 is activated.

[0043] In particular, this also avoids one-sided illumination of the person 260, which, in the case of a video conference, would result in extremely one-sided illumination and thus a very poor quality recording. Of course, it is not necessary for the corresponding parts 30a and 30b of the first light-emitting means 30 to be either completely switched on or off; rather, a corresponding adjustment of the respective intensities to achieve optimal illumination would also be conceivable.

[0044] Preferably, the two sub-regions 35a and 35b of the light-emitting region 35, through which the light is emitted, are designed symmetrically to one another, although there need not necessarily be a sharp drop or jump in brightness at the transition between the two sub-regions. A simple and elegant way to implement the two light-emitting means parts 30a and 30b, for example in the case of fiber optic technology, would be to arrange corresponding LEDs for light coupling on the two downward-facing limbs of the light-emitting region 35 and then, depending on the desired lighting situation, to couple light only from the corresponding direction. This would advantageously result in the intensity of the light emitted via the upper horizontal region of the U-shaped light-emitting surface 35 gradually decreasing, starting from the active light coupling side, resulting in a further improved appearance.However, a strict subdivision would of course also be conceivable, especially when using matrix-like LEDs or OLEDs.

[0045] The light A emitted by the first light emitting means 30 therefore contributes decisively to improving the lighting situation with regard to working on the laptop 20 in the area of ​​the workstation 200.

[0046] Preferably, however, additional light is emitted with the aid of the luminaire 100 according to the invention in order to further improve the lighting situation, which will be explained in more detail below.

[0047] As already mentioned, further light emitting means 40 are provided on the rear side 12 of the lighting fixture 10, which in the illustrated embodiment emit light B towards the rear side over an approximately rectangular flat area 45. As can be seen in particular from the Figures 5a and 5bcan be removed, the area behind the laptop 250 or the lamp 100 can be illuminated with the aid of the light B emitted by these further light emitting means 40, in particular a wall 220 behind it.

[0048] This light emission also results in the correspondingly illuminated areas of the room having a contrast-reducing effect on the luminance of the monitor 255 and the laptop 250. This contributes overall to a better appearance of the entire room and improves the working atmosphere.

[0049] The light emitted by these second light emitting means 40 is therefore only indirectly recognizable for the user 260. In principle, the light emitted by the second light emitting means 40 shown in the figures, in particular in Figure 2The large-area light emission over a larger area 45 shown is not absolutely necessary. For example, the second light emission means 40 could also be implemented in the form of strip-shaped light sources or matrix-like LEDs. However, since the area behind the laptop 250 should still be illuminated with as little local brightness peaks as possible, it is also advantageous for these light sources 40 to emit light over as large an area as possible, which can then be implemented analogously to the first light emission means 30, preferably using fiber optic technology or also using the other technologies mentioned.

[0050] Finally, the particularly preferred embodiment of the luminaire 100 has third light emitting means 50 on the upper side 13 of the light emitting body 10, which, due to the available space, are now designed as a strip-shaped light source extending almost over the entire length of the light emitting body 10. According to the illustration in the Figures 6a and 6bThe light C emitted by these third light emitting means 50 is directed upwards and serves, in particular, to illuminate a ceiling area of ​​a room located above the workstation 200 in the sense of indirect lighting. A "cave effect," which can occur, for example, in the case of insufficient ambient brightness and, in turn, complicates the working situation, can be eliminated in this way. For these third light emitting means 50, it would be advisable to implement them using an elongated LED board, to which appropriate optics are assigned, in order to achieve a homogeneous, elongated light emission.

[0051] Of course, the light output A, B, C of all three light emitting means 30, 40 and 50 can be combined, as shown in the Figures 7a and 7bis shown. In this case, it is preferably possible to individually adjust the light A, B, C emitted by the respective light emitting means 30, 40, 50 with regard to its intensity and / or color or color temperature. This creates the possibility of adapting the various light components to one's own preferences. In particular, it would be conceivable to select a somewhat lower color temperature of the light A emitted by the first or front light emitting means 30 in order to make the illumination of the face of the user 260 appear in a warmer and thus more pleasant color tone, while in contrast the light B or C emitted to the rear or upwards for indirect illumination has a somewhat cooler color tone in order to develop a stimulating effect.

[0052] Overall, an optimal lighting situation for a home office workplace can be created by appropriately controlling the various light emitting devices 30, 40, and 50. Luminaire 100 does not necessarily need to have the two additional light emitting devices 40 and 50 in addition to the first 30 light emitting devices, although these additionally contribute to improving the lighting situation, as explained above.

[0053] A further possibility for adapting the light emission to the specific situation would be to adjust the thickness of the frame-like light emission area 35. In the figures shown, the frame is selected such that it connects essentially borderlessly to the outer periphery of the laptop monitor 255. If a laptop with a smaller display 255 is used instead, a larger distance would result between the outer edge of the display 255 and the light emission area 35. In principle, it would now be conceivable to design the corresponding light emission means 30 such that the thickness D of the frame (see Figure 1) is enlarged (or even the frame is shifted) so that it again fits almost flush with the outer circumference of the laptop monitor 255. This procedure is particularly suitable when using matrix-like LEDs or OLED modules as light sources, since the shape of the area intended for light emission can be changed relatively easily. Furthermore, it would be conceivable to dispense with the transversely running upper area of ​​the light emission area 35 and to realize the light emission of the first light emission means 30 exclusively through two vertical, flat light emission areas running along the sides of the monitor.

[0054] In any case, the design of the first light-emitting means 30 will be such that no light is emitted over the central region of the front 11 of the lighting fixture 10, since this area is shaded by the laptop screen. This free area could now also be used for other purposes. For example, it would be conceivable to place a highly reflective mirror surface here. At times when the luminaire 100 is not being used for home office work, it could then be used, for example, as a makeup mirror. Attaching a simple display, e.g., for a time or temperature display, would also be conceivable. In principle, this area unused for lighting purposes can therefore be used to give the luminaire 100 an additional benefit beyond lighting.

[0055] The inclination of the bracket 20 can be adjusted as already mentioned and as shown in Figure 8As explained above, the angle of the bracket 20 can be adjusted accordingly to adjust the inclination of the luminaire 100 when resting on a horizontal surface. In principle, however, it would also be conceivable to use the bracket 20 for a corresponding mounting on a wall, to which the luminaire 100 would then be permanently attached, but its inclination could again be adjusted accordingly.

[0056] Furthermore, according to the presentation in accordance with Figure 9 the possibility of aligning the bracket 20 completely parallel to the plane of the plate-like lighting fixture 10. The fact that a slightly trapezoidal recess 14a is provided on the underside 14 of the lighting fixture 10 opens up the possibility of using the bracket 20 as a handle and transporting the luminaire 100 easily.

[0057] Preferably, the luminaire 100 according to the invention is designed to be operated at least temporarily without an external power supply source. This means that the luminaire 100 preferably has internal energy storage means in the form of accumulators or the like. An external power supply is provided by means of a Figure 10 This allows the use of the side connector 18 shown, which, for example, enables connection to a power supply cable 270. This can be designed in particular according to the USB-C standard and can either lead to an external power supply or be used to connect the light 100 directly to a laptop. In this case, the connection to the laptop allows the light 100 to be conveniently operated without any additional external power supply.

[0058] Further training in Figure 10The connection option shown consists in using the connection to a laptop additionally to control the luminaire 100. For this purpose, a special user interface could be provided with which the intensity of the individual light emitting means 30, 40, 50 (and possibly the corresponding parts 35a and 35b in the case of the first light emitting means 30) as well as the color or color temperature of the respective emitted light can be conveniently adjusted. Automated or semi-automated control, in particular of the first light emitting means 30, can also be achieved, for example, by using the laptop camera to create a corresponding recording and optimizing the intensity and color temperature of the emitted light accordingly.

[0059] A comparable user interface for controlling the luminaire 100 and for setting the various lighting parameters could also be provided with the aid of a corresponding app on a mobile device, in particular a mobile phone 300, as shown in Figure 11 This is then wirelessly coupled to the luminaire 100 via a corresponding communication connection to enable convenient control. Finally, it would of course also be possible to attach corresponding control elements to the luminaire 100 itself, allowing manual adjustment of the light output.

[0060] The housing of the lamp 100 is formed by the housing of the lighting fixture 10 and is made, for example, of powdered steel or aluminum sheet, which gives the lamp 100 an extremely appealing appearance. It would be conceivable to design the outer shell of the lighting fixture 10 as removable, thus providing different covers that would allow the user to customize the exterior design of the lamp 100, similar to mobile phones. The covers, which can then be snapped or snapped onto the lighting fixture 10, can differ in color and material used. Possible materials include felt, wood, thick fabric, composite plastics, silicone, etc.

[0061] In any case, the present invention provides a novel luminaire that simply and elegantly solves a wide range of tasks in modern lighting technology regarding the illumination of workplaces, particularly in home offices.
