    ARRANGEMENT AND METHOD FOR ILLUMINATING WORKING AREAS
    The present invention relates to an arrangement which is provided for illuminating a work area with one or more workstations. Furthermore, the invention relates to a method for illuminating a work area.
    Compared to the general room lighting is a so-called. Workplace lighting is a very personalized lighting. This is understood that a room, for example, not evenly lit by the arranged on its ceiling lights bright, but instead the light targeted for the illumination of certain areas where work is being done. In particular desk workplaces require a special lighting, which also meets the relevant standards with regard to the available brightness and the question of light incidence. As a rule, a certain minimum brightness must be present at the workplace and the light must be directed onto the work surface in such a way that disturbing reflections and / or glare are avoided.
    Since the position of desks or the like can change frequently, workplace lighting is usually performed by means of lights that are easy to position. Floor lamps have proven to be particularly efficient, which can usually be arranged at any point without much effort and are then used to illuminate a desk. The lights are usually arranged and designed so that they illuminate the entire desk with the associated work or possibly even a desk with two contiguous workstations.
    The present invention has for its object to further improve the above-described concept for illuminating work areas, so that on the one hand comfortable individual lighting of the work areas is achieved, on the other hand, the energy consumption is minimized.
    The object is achieved by an arrangement for illuminating a work area with the features of claim 1 and by a method for illuminating a work area according to claim 10. Advantageous developments of the invention are the subject of the dependent claims.
    The solution according to the invention is based on the idea to design the arrangement for illuminating the work area such that an individually tailored to the use of the work area lighting can be achieved. The lighting means used in this case are designed in such a way that they are capable of illuminating at least two areas of the working area separately or independently of one another. Furthermore, sensor means are provided with whose help information regarding the use of the work area can be obtained. Depending on the information provided by the sensor means available information, the bulbs are then controlled accordingly.
    According to the invention, therefore, an arrangement for illuminating a work area is proposed, which has lighting means which are adapted to illuminate at least two areas of the working area independently of each other. The arrangement according to the invention further comprises sensor means for determining information regarding the use of the working area and control means which control the lighting means in dependence on information provided by the sensor means.
    Further, a method for illuminating a work area is proposed according to the invention, wherein light sources are used, which are adapted to illuminate at least two areas of the work area independently, and wherein first information regarding the use of the work area determined and depending on the Illuminants are controlled.
    The basic idea of the present invention is therefore that, when the work area is illuminated, the total illuminable area is not always uniformly illuminated, but a distinction is made as to whether and how the work area is used. It could therefore be provided, for example, that the work area has two preferably contiguous workstations and then, depending on whether the workstations are actually used, only the occupied spaces are illuminated in accordance with the standards. If, for example, only one of the two workstations is used, then only the corresponding area is illuminated in accordance with standards, whereas, on the other hand, the other unused workstation is not illuminated at all or only with reduced brightness, which would not in itself make it possible to work. Alternatively or additionally, however, it may also be provided to subdivide a single workstation itself again into several subregions and, in turn, to appropriately illuminate these subregions depending on the recognized use of the workstation. This procedure is particularly useful if the workplace occupies a larger area, the corresponding work itself, however, are made only in a portion of this area. In this case as well, it can then be provided that only this subarea is specifically illuminated with a standard-compliant illumination, while, on the other hand, the or further areas in which no work is being performed are only illuminated with a supplementary reduced brightness. Of course, both variants, ie subdivision of a single workstation into several areas and the illumination of only those workplaces of a larger area that are used can be combined.
    The fact that according to the invention only those areas or workplaces are illuminated in accordance with standards that are actually used, the energy consumption of the lighting according to the invention can be significantly reduced. The illumination of all other areas with a certain minimum brightness ensures a more pleasant lighting situation, but nevertheless leads to the targeted energy savings. In this case, the areas to be illuminated by the illuminants independently of one another need not necessarily represent separate areas of the working area. Preferably, there is even a certain overlap, so that hard brightness transitions can be avoided. As will be explained in more detail later with reference to an exemplary embodiment, provision can also be made for certain areas to lie completely within one or more other areas.
    Preferably, all bulbs for lighting the work area according to the invention, but in particular also the sensor means and the control means are part of a single lamp. This may in particular be a floor lamp, but the inventive concept could also be realized with the help of arranged on the ceiling of a room lights.
    The sensor means for obtaining information regarding the use of the workstation may be presence sensors that are targeted to specific areas. Alternatively, however, so-called. Intelligent sensors can be used, which are based on the use of an image sensor and create an image of the work area, which can then be detected with the help of appropriate software routines to what extent individual areas of the workspace are actually used.
    The invention will be explained in more detail with reference to the accompanying drawings. FIGS. 1a and 1b are views of a first exemplary embodiment of an arrangement according to the invention for illuminating a work area; Figure 2 shows a second embodiment of an inventive arrangement Anord workspace lighting; Figure 3 shows a third embodiment in which a single workplace to be illuminated tender according to the present invention is divided into three areas; and FIG. 4 shows a fourth exemplary embodiment of a lighting arrangement according to the invention.
    Figures 1a and 1b show a first embodiment of an arrangement according to the invention for illuminating a work area, in which case the illumination of the work area is made using a single floor lamp. As already mentioned, floor lamps represent the preferred embodiment for realizing the invention, since these are primarily used to achieve an individual workplace lighting. In principle, however, it would also be conceivable to realize the inventive concept with the aid of ceiling lights, in particular suspended ceiling lights, which are thus located relatively close to the areas to be illuminated.
    In the embodiment shown in Figures 1a and 1b, it is initially assumed that with the aid of the floor lamp provided with reference numeral 100, a single workstation 50 - to be shown schematically by the desk 55 - to be illuminated. This workplace 50 is dimensioned relatively large, wherein the lamp 100 is designed such that it is in principle able to illuminate the entire workstation 50 in accordance with standards. That is, the bulbs 115 disposed in the lamp head 110 of the lamp 100 are capable of illuminating the entire surface of the table 55 with a sufficient brightness. Further, the illumination is preferably such that the light is emitted without glare from the lamp head 110 down to avoid disturbing glare or reflections. In the following, however, the direction of the light output should not be considered further. The decisive factor for the present invention is primarily the question with which brightness different areas are illuminated.
    As already mentioned, therefore, the luminaire 100 is in principle designed in such a way that the entire surface of the desk 55 can be illuminated as required by the standards, that is, with high brightness. However, the area of the table 55 is so large that for the actual work usually only partial areas thereof are used, while other areas primarily serve, for example, the storage of documents or the like. A reasonable work at the workplace 50 would already be possible if at least those areas that are used for working, are illuminated sufficiently bright, but all other areas are not or possibly illuminated with reduced brightness.
    According to the invention, therefore, the lamp 100 in addition to the bulbs 115 additional sensor means 120, which are directed to the workstation 50 and are able to recognize whether and, if so, how the workstation 50 is used. Furthermore, the lighting means 115 of the luminaire 100 are designed such that they can illuminate different areas of the workstation 50 independently of each other.
    In the illustrated embodiment, it is initially assumed in a simple manner that the workstation 50 is divided into two areas K1 and K2. The lighting means 115 of the luminaire 100 can illuminate each of these two areas K1 and K2 separately with a variable brightness, it being provided according to the invention that the area in which the workplace 50 is used is illuminated in accordance with the standard, ie with high brightness, during however, the unused area is only illuminated with a reduced brightness. This automated, use-dependent lighting of the workstation 50 is achieved with the aid of the sensor means 120, which are thus able to detect whether one of the two areas K1, K2 or possibly both areas are used. The information obtained by the sensor means 120 is then forwarded to a arranged in the lamp head control unit 125, which takes over a corresponding control of the lighting means 115. Of course, it can be provided that the bulbs 115 are generally activated only if a use of the workstation 50 has been detected at all.
    The design of the lighting means 115 such that the two areas K1 and K2 can be optionally illuminated with an individual brightness, can be done in any way. It will make sense to each be separate light sources, each of which is associated with a corresponding optics, so that the light of the respective light source is directed to the associated area. It is not necessary - as shown - to have a separation between the two areas K1 and K2. Ideally, these areas will even overlap slightly to avoid too much brightness variations in the transitional and / or vertical areas. To avoid borderline. However, it is essential that the entirety of the areas to be individually illuminated, in the present case, the areas K1 and K2, cover the entire workstation 50.
    Bzgl. The sensor means 120 for recognizing whether and, if so, which of the areas K1 and K2 is used for work also has various possibilities for realizing them. For example. Simple presence or movement sensors can be used, in which case each individual area is assigned a single sensor. That is, according to the number of the separately illuminable areas, there are also a number of individual sensors, and then the area detected by a single sensor corresponds to the corresponding area to be illuminated. In other words, in the exemplary embodiment of FIGS. 1a and 1b, two sensors would have to be used which each detect the region K1 or K2.
    An alternative and more convenient option would be to use an intelligent sensor based on the use of image acquisition means. In this case, therefore, the entire workstation 50 is optically detected with the aid of the image acquisition means and it is determined by appropriate evaluation of the image whether and, if so, one of the subregions K1 and K2 is used. Such intelligent sensors are already known, for example, from DE 10 2010 003 804 A1 of the Applicant.
    The solution according to the invention thus allows the workstation 50 to be illuminated at any time with the brightness provided in accordance with the standard. However, depending on the usage, appropriate lighting only takes place for those areas that are actually being used. Other areas that do not require appropriate lighting are either not illuminated or only with reduced brightness, so that overall energy consumption can be reduced while maintaining high quality workplace lighting. It can of course be provided that in the illumination of individual areas in addition also the incident from the outside daylight is taken into account. In this case, in turn, the preferred, above-mentioned intelligent sensor is used, since the image information at the same time also provide information about the brightness present at the areas to be illuminated, thus enabling immediate consideration of the daylight.
    Furthermore, it should be pointed out that - in turn, in particular when using the intelligent sensor - could also be provided to arrange this not directly on the lamp 100, but separately therefrom. The sensor 120 then communicates in a corresponding manner with the control unit 125 of the luminaire 100.
    A second embodiment of a lighting arrangement according to the invention is shown in FIG. In this case, it is assumed that the luminaire 100 serves to illuminate a working area 60 which has two mutually opposite workstations 50i and 502. In the present case, no subdivision of the individual workstations 50! and 502, but there is only a subdivision of the entire workspace 60 into the two workstations 50i and 502. Again, these areas K1 and K2 can be individually illuminated by the luminous means 115 of the luminaire 100, wherein according to the invention a usage-dependent illumination takes place. It is thus determined in this case whether one of the two workstations 50i or 502 is used or not. This is then illuminated according to the standard. Of course, in the event that both places are used, both areas are illuminated accordingly. The procedure corresponds to that of the embodiment according to FIGS. 1a and 1b. The sensor means can also be designed in a corresponding manner.
    A third embodiment, which represents a development of the example of Figure 1, is shown in Figure 3, again starting from a single workstation. However, this is now divided into three areas K1, K2 and K3, wherein the first two areas K1 and K2 correspond to the two halves of the table, as was the case with the embodiment of Figures 1a and 1b. The third area K3 represents a central focus in the area of the workstation 50, which may possibly be illuminated with a particularly high brightness in order to allow a special work at high brightness. This area K3 would, for example, be specifically illuminated if use of the workstation 50 in this central area is detected. In this case, the other areas K1 and K2 can then be illuminated with reduced brightness.
    Thus, it can be seen from this third exemplary embodiment that the individual regions do not necessarily have to be defined separately from one another, but that it may well be the case that one region lies completely within another or several other regions, as provided here.
    Finally, FIG. 4 shows a combination of the exemplary embodiments of FIGS. 2 and 3. In this case, once again a single luminaire serves to provide a working area 60 with two workstations 5Ü! and 502 to illuminate, each of the two jobs as in the variant of Figure 3 has three areas K1, K2 and K3 or K4, K5 and K6, which can be illuminated depending on the use of an individual brightness.
    Of course, it would be conceivable to define more than the six areas shown in Figure 4 within a workspace. However, since this also involves a more complex design of the bulbs, the number of areas should not be too high. The illustrated embodiments represent particularly preferred variants, in which the resulting overhead in terms of the design of the bulbs is justifiable and in particular be outweighed by the resulting advantages in terms of flexible, energy-saving lighting.
