    The invention relates to a lighting system for illuminating a room, and a method for controlling such a lighting system.
    From the applicant, a ceiling light for lighting a room under the name "Mild Light" is sold. On the one hand, this luminaire can be used to brighten a ceiling area and, on the other hand, to illuminate a work area locally. To control the lamp is provided that the lighting of the ceiling area is reduced by dimming when the work area is sufficiently lit by the daylight. This can lead to the ceiling area appearing comparatively dark, so that a negative mood is triggered by a person in the room.
    The invention has for its object to provide a corresponding improved lighting system and an improved method for driving a corresponding lighting system. In particular, it should be possible with the lighting system or with the method to produce a particularly positive lighting effect with a total energy-efficient use.
    This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are indicated in the dependent claims.
    According to the invention, an illumination system for illuminating a room is provided which has means for generating a large-scale room brightening, and means for generating a concentrated, local lighting. Furthermore, the lighting system has presence detection means for detecting presence of at least one person in the room, and control means for controlling the means for generating the room lighting and the means for generating the local lighting. In this case, the control device is designed to automatically control the large-area room lighting daylight-dependent or time of day and the local lighting automatically in response to the presence of at least one person in the room.
    The fact that the brightening is automatically controlled as a function of daylight or the time of day, can be avoided that the brightening is reduced so much that a negative-looking lighting mood arises. Nevertheless, the lighting system can be energetically advantageously controlled, in particular, since the local lighting can be controlled as a function of the presence of persons in the room.
    Preferably, the means for generating the brightening room are designed to generate a large-area light output from a ceiling region of the room, wherein the means for generating the local lighting are configured to, in at least one of a plurality of sub-areas located below the ceiling areas To produce work lighting. By brightening the ceiling area, a particularly advantageous effect of the light on the well-being or mood of a person present in the room can generally be achieved.
    Preferably, the presence detection means is adapted to detect whether at least one person is present in at least one of the subregions and, if so, in which or in which of the subregions, the design further being as follows: the means for generating the local illumination are controlled so that only that of the sub-areas is illuminated in which at least one person is present or possibly only those of the sub-areas are lit, in which at least one person is present. As a result, a particularly large energy-saving potential can be achieved. In particular, the design is furthermore preferably furthermore as follows: the means for
    Generation of the local lighting remain disabled as long as no person is present in at least one of the subregions.
    Preferably, the lighting system further comprises a daylight detecting means for detecting an intensity of a daylight present in the room, the design further being as follows: the means for generating the local lighting remain activated as long as at least one person in at least one of Partial areas is present and the intensity of daylight falls below a threshold and remain disabled as long as the intensity of daylight exceeds the threshold. This makes it possible to achieve even better energy savings.
    The means for generating the brightening of the room are further preferably designed to produce the room brightening in different intensities, wherein the design is still as follows: the means for generating the brightening of the room are controlled so that the room brightening with increasing intensity of daylight is generated with increasing intensity. This makes it possible to achieve a particularly positive mood influence through the room brightening.
    Preferably, the means for generating the brightening of the room are further adapted to produce the room brightening in different color temperatures, wherein the daylight detecting means is further configured to detect a color temperature of the daylight and wherein the design is further as follows: the means for generating The brightening of the room will continue to be controlled in such a way that as the color temperature of the daylight increases, the room brightening will be produced with increasing color temperature. By choosing the color temperature of the room brightening, the latter's effect can be adapted particularly well to the daylight.
    Moreover, the means for generating the local illumination are furthermore advantageously designed to generate the local illumination in different color temperatures, the design still being as follows: the means for generating the local illumination are further controlled so as to increase Color temperature of daylight the local lighting is generated with increasing color temperature. As a result, the effect of the local lighting can be adapted particularly well to that of daylight.
    According to another aspect of the invention, there is provided a method of driving a lighting system to illuminate a room, comprising the following steps: a) detecting whether at least one person is present in the room, b) scheduling means for generating a large area ceiling lighting and means for generating a concentrated, local lighting, wherein the large-scale room lighting is automatically controlled daylight-dependent or time of day-dependent and the local lighting automatically in response to the presence of at least one person in the room.
    The fact that the room brightening is automatically controlled depending on the daylight or the time of day, can be avoided that the brightening is reduced so much that a negative light mood. Nevertheless, an energetically particularly advantageous control can be achieved, since the local lighting can be controlled as a function of the presence of persons in the room.
    Further advantageous with respect to the use of energy, the means for generating the local lighting are preferably configured to generate in at least one of a plurality of sub-ceiling areas located below a portion of the work lighting, wherein the means for generating the local lighting be controlled so that only that of the sub-areas is lit, in which the at least one person is present or possibly only those of the sub-areas are lit, in which the at least one person is present. In particular, the means for generating the local illumination preferably remain deactivated for this purpose, as long as no person is present in at least one of the subregions.
    Preferably, an intensity of a daylight present in the room is further detected, wherein the means for generating the local lighting remain activated as long as at least one person is present in at least one of the subregions and the intensity of the daylight falls below a threshold value and remain deactivated as long as the intensity of daylight exceeds the threshold. In this case, the means for generating the brightening of the room are furthermore preferably controlled so that the room brightening is generated with increasing intensity as the intensity of the daylight increases.
    Preferably, a color temperature of the existing daylight in the room is further detected, wherein the means for generating the brightening of the room are further controlled so that the room brightening is generated with increasing color temperature with increasing color temperature of the daylight.
    Preferably, the means for generating the local illumination are further controlled so that the local illumination is generated with increasing color temperature with increasing color temperature of the daylight.
    The invention will be explained in more detail below with reference to an embodiment and with reference to the drawings. 1 shows a schematic sketch of an illumination system according to the invention for illuminating a room, FIG. 2a shows a schematic sketch of the room with several persons present, FIG. 2b shows a schematic sketch of the room with only a person present, FIG. 2 c shows a schematic sketch of the room without a present person, FIG. 3 a shows a schematic sketch of the room with several persons present, wherein a daylight-dependent control of the lighting system is provided, [0025] FIG. Fig. 3b is a schematic sketch of the room with a presenter detected by a presence detector; and Fig. 3c is a schematic sketch of the room with a presence detector without a present person.
    1 shows a schematic sketch of an illumination system according to the invention for illuminating a room R. The room R may be, for example, a large room which has several work areas or is subdivided into several work areas. For example, a workstation may be provided at each of the workspaces. The room R may be, for example, an open-plan office or a classroom or the like.
    The illumination system comprises means 4 for generating a large-area room lighting. These can in particular be designed to generate a large-area light output from a ceiling area 2 of the room R. The ceiling area 2 may in particular be the entire ceiling area of the room R or may comprise a partial area of at least 50% of the total ceiling area of the room R.
    Also, the means 4 for generating the brightening of the room can advantageously be designed to additionally lighten a lateral wall area and / or a floor area of the room 3.
    Furthermore, the lighting system comprises means 5 for generating a concentrated, local lighting 5. These can be designed in particular to at least one of several, located below the ceiling area 2 sub-areas 1, T, 1 "of the room R work lighting or workplace lighting For example, each of the subareas 1,1 ', 1 "may comprise exactly one of the work areas.
    In particular, the means 5 for generating the local illumination 5 can be designed to generate work lighting or workstation lighting independently of one another in each of the subregions 1, T, 1 ".
    The lighting system is accordingly adapted to emit light in two different ways. For the brightening of the room, a rather less intense, but larger-scale light generation is provided and for the local lighting a smaller-scale, but more intense light generation, in particular a lighting, with each workstation can be illuminated independently of the rest of the workplaces.
    Furthermore, the lighting system comprises a presence detector 6 for detecting a presence of a person Pin the room R.
    Furthermore, the lighting system comprises a control device 8 for controlling the means 4 for generating the room lighting and the means 5 for generating the local lighting.
    The control device 8 is designed to automatically control the large-scale room lighting daylight-dependent or time of day and the local lighting automatically depending on the presence of at least one person pin the room R. In the example shown here, the presence detection device 6 is advantageous for this purpose designed to detect whether at least one person P is present in at least one of the subareas 1, T, 1 "and, if so, in which of the subareas 1, T, 1" or optionally in which of the subareas 1, T, 1". In this case, the space R can be so completely subdivided into the subregions 1, T, 1 "that it is possible to detect with the presence detection device 6 whether a person Pin is in the room Ranwesend.
    In particular, the control device 8 is configured to control the means 4 for generating the brightening of the room independently of the means 5 for generating the local lighting.
    In this case, the control device 8 is further configured so that the means 5 for generating the local illumination are controlled so that only that of the subregions 1, T, 1 "is illuminated, in which at least one person P is present or optionally only those partial areas 1, T, 1 "are illuminated, in which at least one person P is present. Accordingly, the control device 8 is advantageously connected to the presence detection device 6 for the corresponding information transmission.
    In particular, so the design can be such that the control of the means 4 for generating the brightening takes place regardless of whether a person pin the room R or in one of the subareas 1, T, 1 "or whether several more Keep persons P in the room P or in one of the partial areas 1,1 ', 1 ".
    Of course, in addition can be provided energetically advantageous that the means 4 are disabled to produce the room lighting, if no one in the room R or in one of the subareas 1, T, 1 "and remain deactivated as long as so long this condition exists.
    In the example shown, the presence detection device 6 comprises presence sensors, with the aid of which it can be detected whether a person is located in one of the subareas 1, T, 1 "and optionally in which of the subareas 1, T, 1" For example, exactly one of the presence sensors can be provided in each of the subareas 1, T, 1 "for this purpose.
    Energetically advantageous for driving is provided that the means 5 for generating the local lighting disabled or remain off as long as no person in at least one of the sub-areas 1, T, 1 "is present.
    In the example shown, the lighting system further comprises a daylight detection device 7, for example in the form of a light sensor, for detecting an optionally existing in the room R daylight. The design of the control system is such that the means 5 for activating the local illumination remain activated as long as at least one person is present in at least one of the partial areas 1, T, 1 "and the intensity of the daylight falls below a threshold value However, if the intensity of the daylight exceeds the threshold value, the means 5 for generating the local illumination remain deactivated, which is energetically advantageous.
    Accordingly, the threshold is preferably set such that at each of the workplaces there is a light which is suitable for work, for example reading or writing, when the intensity of daylight is above the threshold.
    Furthermore, the means 4 for generating the brightening of the room are preferably designed to generate the room brightening in different intensities, wherein the means 4 for generating the brightening of the room are controlled so that the room brightening is generated with increasing intensity with increasing intensity of the daylight. In particular, it can be provided that the control is such that the intensity of the daylight is "simulated" with the means 4 for generating the brightening of the room.
    By activating the means 4 for generating the brightening of the room can be particularly avoided that in the case where only one workplace is lit or only a small part of the workplaces is illuminated, the room Rais "dark cave" appears.
    Similarly, it may further be provided that the means 4 for generating the room brightening are further configured to generate the room brightening in different color temperatures, wherein the daylight detecting device is further configured to detect a color temperature of the daylight. The means 4 for generating the brightening of the room are thereby further controlled so that the room brightening is generated with increasing color temperature with increasing color temperature of the daylight. This makes it particularly suitable to create an effect of room whitening, which "simulates" the effect of daylight.
    Also, the means 5 for generating the local illumination can be configured to generate the local lighting in different color temperatures, the means 5 for generating the local lighting are still controlled so that with increasing color temperature of the daylight, the local lighting increasing color temperature is generated.
    With the thus designed lighting system or the thus designed control of the same, thus, the energy requirements of the system can be kept low and still achieve a positive effect on the well-being of the persons present in the room R. In particular, it can be achieved that the comparatively energy-intensive local illumination is emitted only if this is desired on the basis of the currently prevailing brightness and the presence of one person or several persons. The less intensive, large-scale brightening of the room, on the other hand, is given off in particular when only a few workplaces are illuminated with the means for generating the local lighting, for example at a later hour in a large office, when comparatively few workstations are occupied. This can cause a positive room mood.
    Sketches of the space R for different lighting situations are shown schematically in FIGS. 2a to 2c. In Fig. 2a, a case is sketched in which several people P are present in the room R and are illuminated accordingly by the means 5 for generating the local lighting several work areas or places. As indicated in the sketch, the design may be such that the means 4 for generating the room lighting and the means 5 for generating the local lighting by several, in the example sketched three ceiling lights D are realized, preferably each of the ceiling lights D a first light emitting area D1, over which the light is emitted to produce the brightening of the room and a second light emitting area D2, through which the light is emitted to produce the local lighting.
    The second light emitting area D2 can represent a partial area of the first light emitting area D1. For example, as indicated above, the first light emitting area D1 may be oblong and the second light emitting area may thus also have an elongate, middle subregion of the first light emitting area D1.
    The ceiling lights D may be, for example, surface-mounted or recessed ceiling lights. In principle, however, it can also be provided for the lighting system that individual luminaires are used which emit the light in the two different types. However, the concept can also be applied to larger lighting arrangements, which may consist of several, possibly even different lights.
    In Fig.2b, the space Rmit of a person present P is sketched. Accordingly, only one workplace is illuminated, in the example shown by the middle of the three ceiling lights D. The two side ceiling lights D therefore do not emit light for generating a local illumination via the second light emitting area D2. But all three ceiling lights D emit a light to create the room lighting.
    In Fig.2c the room Rohne person is sketched. Accordingly, the three ceiling lights D are activated in such a way that the means 5 for the generation of the local illumination are deactivated, ie no light is emitted via the second light emission area D2 for generating a local illumination.
    In Fig.3a a corresponding schematic sketch of the room R is shown with several persons P present, with a daylight-dependent control of the lighting system is provided, as shown by a sun S symbolically.
    Fig. 3b shows a schematic sketch of the room R with a person P present. The presence of the person P is detected by a presence sensor which is part of the presence detector 6. The presence detector 6 also detects in which of the sections the person P is located; This information is transmitted from the presence detection device 6 to the control device 8. By the latter, the means 5 for generating the local illumination are then activated in such a way that a work lighting is generated in that of the subregions in which the person is located. In other areas where no people are present, no workplace lighting is generated. Accordingly, the control is such that only in one of the three ceiling lights D, here the middle ceiling light, the means 5 are activated to produce the local lighting.
    Fig. 5c shows a corresponding sketch showing the space R without presence of a person. It can be detected by the presence detection device 6 that no person is located in one of the subareas, in particular that no person P is in the room R.
