Definitions

  • the present invention relates to a luminaire intended for illuminating a workplace, in particular for illuminating a home office workplace.

  • the diffuser system comprises a plate which is essentially adjacent to the LCD display unit and extends away from the LCD display unit.
  • the plate is configured in such a way that it couples in light emitted by LEDs, redirects it and couples it out as ambient light by means of interruptions in the plate.
  • the DE 200 21 973 U1 discloses a picture frame-like night lamp consisting essentially of a translucent front panel, 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 to radiate light onto the light guide plate, which reflects the light outward, thereby illuminating the picture framed in the front cover, thus forming a picture frame-like night lamp.
  • 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.
  • the core idea of the present invention is to provide a lamp that can be used in a simple and flexible way to create optimized lighting conditions in the space used for home office work. It is assumed that home office work takes place predominantly with the help of a laptop or a comparable portable work device, whereby the lamp according to the invention is then initially designed to illuminate the area around the laptop and a person using the work device as glare-free as possible.
  • the lamp has a plate-like lighting body as a central element, which can be positioned essentially vertically with the help of suitable fastening means and can be arranged in particular behind the display of a laptop.
  • First light emitting means are then provided on a front side of the plate-like lighting body, which is formed by a flat side of the lighting body, which emit light over a frame-like surface area framing the screen of the laptop.
  • the lamp 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 screen of the laptop and emits light onto the area in front of the laptop as well as onto a person using the laptop.
  • the readability of the display of the work device is also improved, since the non-glaring frame-like light emission reduces the contrast compared to the surroundings, making it easier for the viewer to adapt to the eye.
  • the light emission according to the invention with the help of the first light emission means also helps to illuminate the person themselves, which leads to a significantly improved appearance with regard to the video conferences mentioned above.
  • the lighting situation for home office work on a laptop or a comparable work device is thereby significantly improved.
  • the inclination of the lighting fixture can be adjusted, for example, relative to a base. Just as the inclination of a laptop display can usually be changed, the inclination of the lighting fixture can also be adjusted accordingly, so that it is ensured that the screen fits optimally into the frame-like light output by the first light source.
  • the first illuminants are preferably designed in such a way that they emit light without glare. This is particularly advantageous because the light produced by the first As already explained, the light emitted by the light emitting device is also directed directly at the user of the lamp and, of course, annoying glare should be avoided here.
  • 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, whereby 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 is often very one-sided at workstations located near windows. This can then be compensated for by the corresponding sub-area of the frame-like surface area only emitting light with reduced brightness or no light at all, while the other sub-area, from whose direction there is no natural light, emits more light.
  • This also contributes, particularly when conducting video conferences, to ensuring that the face of a participant is not only illuminated from one side, but instead is optimally illuminated overall.
  • the lamp according to the invention can also be used to improve the lighting situation in the room as a whole.
  • further light emitting means are provided on a rear side of the lighting fixture opposite the front side, which are designed to emit light in an opposite direction.
  • these further light emitting means which preferably emit light over a large area and in particular also diffusely towards the rear side, the area of a room behind a workstation or a wall behind the workstation can then be illuminated.
  • This also contributes to improving the working situation, since the laptop display and the frame-like lighting are no longer the only large-area light source in the room, but the room as a whole has a certain basic brightness. This leads to an additional reduction in strong brightness contrasts, which would have an unpleasant effect on the working situation.
  • further light emitting means are provided on a narrow side connecting the front and back of the lighting fixture. These are then used in particular to emit light towards the top and, for example, to illuminate the ceiling of a room above a workstation in the sense of indirect lighting. In an analogous manner, this makes the entire lighting situation in a room more pleasant, which contributes to improving the user's well-being.
  • all of the light emitting means provided by the lamp can be adjusted independently of one another, in particular with regard to their intensity and their color location or color temperature. Adjusting the color temperature, in particular of the light used for rear lighting and indirect lighting, can serve to further improve well-being by using so-called circadian stimulating light. Depending on the time of day or the user's wishes, a color temperature for the light can then be selected, for example, which has a more stimulating effect on the user in order to sharpen 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 advantageous in order to create optimal lighting for a camera shot from the user's perspective.
  • the lamp can also be designed in such a way that it can be coupled to a PC, whereby the coupling can be used in particular for the energy supply and/or also for controlling the lamp. For example, a connection to a laptop via a corresponding USB port would be conceivable, so that the use of a separate energy supply source can be dispensed with.
  • a particularly convenient or partially automated setting of the light output of the various light emitting means could also be carried out within the framework of an appropriately designed user interface.
  • a corresponding control device e.g. in the form of a mobile phone - or with the help of corresponding control elements that are arranged directly on the lamp.
  • 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.
  • the lamp according to the invention is intended to largely solve the problems of efficient lighting in connection with the use of a laptop for home office activities, even from a professional point of view.
  • the problem of differences in luminance between the monitor and the environment and the associated glare can be efficiently eliminated with the help of the lamp according to the invention.
  • circadian effective light can be emitted within a wide color temperature spectrum in order to achieve a high feel-good factor that enables fatigue-free work and a high level of concentration.

  • a C-shaped bracket 20 is attached to two long sides 15 and 16 of the lighting body 10, which 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.
  • the lamp 100 is stable on the one hand thanks to the cross-connecting leg 21 of the bracket 20, with the lamp 100 also resting on the underside 14 of the lighting body 10 for further support.
  • the support bracket 20 can be pivoted about its two suspension points 22 and thus an axis running parallel to the underside 14 of the lighting body 10, the inclination of the lighting body 10 relative to the surface on which the lamp 100 rests can be adjusted, in particular to the inclination of the laptop screen located in front of it.
  • the lamp 100 has several light emitting means in order to fulfil various lighting tasks.

  • second light emitting means 40 are provided on the rear side 12 of the lighting body 10 opposite the front side 11, which now emit light towards the rear side over a larger area 45.
  • third light emitting means 50 are provided on the upper side 13, which connects the front side 11 and rear side 12 of the lighting body 10, the light of which 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.
  • the lamp 100 according to the invention in the illustrated, particularly preferred embodiment has three different light emitting means 30, 40 and 50, which each emit light in a different way and thereby fulfill different lighting tasks. These lighting functions will now be described below with reference to the Figures 3 - 7 be explained in more detail.
  • the Figures 3a and 3b first illustrate the light emission A by the first light emission means 30, which are arranged on the front side 11 of the lighting body 10. Shown in Figure 3a the situation of using the lamp 100 at a workstation 200, which can 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 3a a person using the workstation 260 is shown.
  • 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. Placed in front of or next to the laptop 250 This lighting makes it easier to read documents, especially when the ambient lighting does not provide sufficient light.
  • a further effect of the light A emitted by the first light emitting means 30 is that the person 260 himself is illuminated with a certain brightness. This is particularly advantageous if 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.
  • the lighting provided at a home office workstation is often not sufficient for optimal video recording or the color temperature of the available light has a negative effect 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 corresponding additional lighting.
  • the light A emitted by the first light emitting means 30 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 since 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.
  • the frame-like light emitting area 35 of the first light emitting means 30 is designed in such a way that it is as close as possible to the outer circumference of the laptop screen 255, or at least is not covered by it.
  • the light emitting area 35 should therefore be dimensioned in such a way that a screen 255 of a standard size (for example, a size of 16 inches represents a reasonable upper limit) fits into the area framed by the downwardly oriented "C".
  • a screen 255 of a standard size for example, a size of 16 inches represents a reasonable upper limit
  • the distance between the screen 255 and the light emitting area 35 would then increase, whereby at a later date
  • a further development of the luminaire 100 will be explained, which allows an adjustment of the light emission range 35 within certain limits.
  • the first light sources 30 therefore emit light A towards the front. Since this light is also directed directly at the user 260, it must be ensured that glare is avoided. In particular, glare-free light emission is aimed for, which is made possible by using a light emission area 35 that is as large as possible and thus rather low luminance, whereby the light should be emitted as homogeneously as possible over this area 35.
  • the first light emitting means 30 can be implemented in a variety of ways.
  • a corresponding matrix-like arrangement of LEDs on so-called backlight boards, preferably of micro-LEDs would be conceivable, in front of which optical elements in the form of a microprism optic, films, diffusers and the like are arranged in order to convert the light from the essentially point-shaped LED light sources into a light emitted homogeneously over a surface.
  • OLEDs organic LEDs
  • a preferred variant for the realization of the first light emitting means 30, however, consists in forming the frame-like light emitting area 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, a uniform light coupling over the entire area 35 can then be achieved by means of appropriate light coupling structures, e.g. in the form of microprisms, so that a completely homogeneous light emission is achieved over the U-shaped area.
  • the realization of the first light emitting means 30 with the aid of the just described The light guide technology explained also has the advantage that in this case the lamps can be realized with a very small thickness, which has an advantageous effect on the dimensions, in particular the thickness of the lighting body 10.
  • first light emitting means 30 are divided into a first part 30a located on the left side of the front 11 and 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 means that, as can be seen from 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 are only illuminated from the corresponding direction.
  • This partial use of the first light emitting means 30 can be particularly desirable if the natural lighting situation of the workstation 200 includes one-sided natural lighting. This can be the case, for example, if the workstation 200 is located laterally near a window through which natural daylight enters.
  • the workstation 200 is located laterally near a window through which natural daylight enters.
  • the opposite left side of the room is rather dark.
  • one-sided illumination of the person 260 can be avoided, which in the case of a video conference would lead to very one-sided illumination and thus to a very poor quality recording.
  • the corresponding parts 30a and 30b of the first light emitting means 30 are either completely on or off, but a corresponding adjustment of the respective intensities to achieve optimal illumination would also be conceivable.
  • the two sub-areas 35a and 35b of the light emitting area 35 are designed symmetrically to one another, whereby there does not necessarily have to be a sharp drop or jump in brightness at the transition between the two sub-areas.
  • a simple and elegant way of implementing the two light emitting means parts 30a and 30b would be, for example in the case of light guide technology, to arrange corresponding LEDs for coupling in light on the two downward-facing legs of the light emitting area 35 and then, depending on the desired lighting situation, to only couple in light from the corresponding direction.
  • 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.
  • 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.

  • 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 in a relatively simple manner. It would also be conceivable to dispense with the transverse upper area of the light emission area 35 and to implement the light emission of the first light emission means 30 exclusively by two vertical, flat light emission areas running to the side of the monitor.
  • the design of the first light emitting means 30 will be such that no light is emitted over the central area of the front 11 of the lighting body 10, since this area is shaded by the laptop screen.
