    LIGHTING SYSTEM AND ARRANGEMENT WITH MULTIPLE SENSORS FOR DETECTING MOTION OR PRESENCE
    The invention relates to an arrangement with a plurality of sensors, which each detect a movement or a presence, and a lighting system with such an arrangement with sensors.
    In areas such as larger buildings or outdoors, in which a plurality of lights are arranged, it is desirable to activate these lights as needed. For example, in a long hallway, only the part of the length that a person is currently in needs to be fully illuminated. However, for static applications it can also be desirable if only one area around a person, e.g. at a workplace, is brightly lit, while the greater the distance from this person, only a reduced illuminance is achieved. A corresponding system is described in WO 2011/134003 A1. Here a person is detected by a motion detector and a signal is then transmitted from the light to its neighboring lights, which in turn send information about their current lighting status to the other neighbors. The system described is relatively complex and requires that the operating devices of the luminaires or the luminaires themselves pass on information about their current lighting status.
    It is the object of the invention to provide a simple way with which an adapted lighting can be realized. The object is achieved by the arrangement with a plurality of sensors or by a light system that uses such an arrangement.
    The sensors of the arrangement can detect movements or presence in different areas. For this purpose, each of the sensors of the arrangement can detect a movement or presence in a first detection area and in a second detection area that differs from the first detection area. The sensors are arranged in such a way that the second detection area of each sensor overlaps with at least one second detection area of another sensor. When the presence or movement of a person is detected, the sensors output distinguishable signals, depending on in which of the two detection areas of the sensor the presence or movement was detected. In this way, when a person is recognized in the first detection area by the assigned luminaire, for example, a high level of illuminance can be achieved, while the luminaire of the lighting system receives the information from its assigned sensor that the movement or presence in the second detection area has been detected , is set to a different lighting level.
    By overlapping the areas, the neighboring lights can be included. This means that not only a single luminaire (or group of luminaires) is operated with one illuminance, but the neighboring luminaires can also be set to an adapted lighting level.
    The subclaims define advantageous developments of the arrangement and of the lighting system according to the invention. In particular, it is advantageous if the second detection area surrounds the first detection area of the same sensor. If, for example, one looks at sensors attached to a ceiling of a building that are supposed to monitor a room, the first detection area, for example when projecting onto the floor opposite the sensor, would correspond to a circle that is surrounded by a circular disk that forms the second detection area. If the second detection area surrounds the first detection area, this has the advantage that there is a direction-independent behavior for this sensor.
    Furthermore, it is advantageous if the sensors are arranged such that the respective first detection areas adjoin at least one first detection area of another sensor. This makes it possible, for example, for a person to move from a first
    The detection area of a sensor is moved into the first detection area of the adjacent sensor. If, for example, it is defined that as soon as a person moves into this first detection area, the assigned luminaire or group of luminaires is operated with maximum illuminance, the area currently required by the person is well illuminated. If, on the other hand, there is a person in the second detection area, a lower, second illuminance can be provided for this area. It is particularly advantageous if the respective second detection area of a sensor overlaps with the first detection area of another sensor. As a result, when a luminaire or group of luminaires is operated with maximum illuminance because a person is in the first detection area of this sensor, the adjacent luminaire or group of luminaires of that sensor whose second detection area overlaps the first detection area of the other sensor can be set to a lower illuminance at the same time become. If a person moves through the detection areas of the sensors, the assigned lamp is operated with maximum illuminance where it is located in the first detection area, but at the same time the lamp in whose second detection area the person is located is operated with a lower illuminance operated. This results in a larger illuminated area, with a focus where the person is currently located.
    It is also advantageous if the sensors have communication means so that they can exchange information with one another. In particular, it is advantageous if the presence or a movement in the second detection area of a sensor is transmitted from this sensor to at least one further sensor with the aid of an information signal. This means that even before the person gets into the detection range of the other sensor, this sensor can be informed that a movement is to be expected. Accordingly, preprocessing or a system start-up can already be carried out before a movement is actually registered by the receiving sensor. It is also possible that on the basis of this received information signal, the receiving sensor outputs a signal to an operating device assigned to it, as a result of which the luminaire assigned to it is operated with a third, possibly even lower, illuminance.
    In order to prevent the occurrence of an undesirably fast switching between different illuminance levels during a successive detection of movement or the presence of a person in the two detection areas, it can be provided that the reduction of the illuminance only occurs after a certain minimum operating time has elapsed at an illuminance he follows. If a person moves from a second detection area into a first detection area and out again into the second detection area, the corresponding sensor sends the information signal that a movement or presence was detected in the second detection area to another sensor twice. In order to prevent the luminaire or luminaire group assigned to the receiving sensor from being switched off again while the person is in the first detection area of the sensor, a minimum operating time is maintained. In the case of typical movements in which the person walks through the different detection areas of the multiple sensors of the arrangement, it can thus be avoided that the lamp switches off and then switches on again shortly afterwards due to a newly received information signal.
    The invention is explained in detail below with reference to the accompanying drawings. Show it:
    1 shows a lighting system according to the invention with an arrangement of sensors according to the invention in a first view;
    [0012] FIG. 2 shows a projection of the detection areas of an individual sensor of the arrangement onto the ground; and
    3 shows a projection of the detection areas of an arrangement of sensors according to the present invention.
    Figure 1 shows the arrangement of three lights in the example, which are arranged, for example, along a straight line on a ceiling of a room in a building. Such a room can be a hallway, for example, with the lights 1, 2 and 3 being distributed along the longitudinal direction and arranged at a distance from one another.
    Typically, in such a hallway, the lights 1, 2 and 3 are on a line with equal distances from one another. Each lamp has a sensor 4, 5 and 6, which is assigned to it, and based on whose signal the respective lamp 1, 2, 3 is switched. An operating device 7, 8, 9 is also provided for operating the lamp 1, 2 and 3. The sensors 4, 5, 6 each have at least one first output and one second output, which is connected to corresponding inputs of the operating devices 7, 8, 9. Depending on a detected movement or presence, the sensor 4, 5, 6 emits an output signal via its first or second output. The output signal can be wired and / or wireless (Bluetooth, infrared, WLAN,...) From the sensor 4, 5, 6.
    As an alternative to the use of two separate outputs, via each of which an output signal, only a single output can also be used, the output signal output via this then differing for the different detection areas. The operating device 7, 8, 9 thus receives information from the sensor 4, 5, 6 in which of the multiple detection areas of the sensor 4, 5, 6 a movement or presence was detected.
    In the illustrated embodiment, both the lights and the operating devices and sensors are of identical design. The sensor 6 has a first, inner detection area 10 surrounded by a second, outer detection area 11. FIG. 1 shows that the sensor 4, as the inner detection area 10, has an area that is exactly opposite the sensor 4, whereas the outer detection area 11 runs around this inner detection area 10. The sensors 5 and 6 also each have an inner detection area 12 and 14 and an outer detection area 13 and 15, respectively.
    In Figure 2, the boundaries of the first detection area 10 and the second detection area 11 for the sensor 4 are shown as an example, as they run on the opposite floor of the room or hallway from the sensor 4. It can be seen that the inner detection area 10 has a circular boundary and the outer detection area 11 likewise has a circular outer boundary which runs concentrically to the boundary of the inner detection area 10. The sensor 4 is located in the center of the circular boundaries and is thus exactly opposite the center point 16. The first detection area 10 is thus - in a projection onto the floor - a circular area and the outer detection area 11 is a circular disk.
    Alternatively, the boundaries can have other geometric shapes, such as triangle, square, trapezoid, etc.
    Returning to FIG. 1, it can be seen that the sensors are arranged such that the outer detection area 11 of the sensor 4 overlaps the inner detection area 12 of the sensor 5 and the inner detection area 14 of the sensor 6. If a person now moves along the depicted hallway in the direction of the arrow, he or she, coming from the left, will first come into the outer detection area 13 of the sensor 5. If it moves further, it will next enter the inner detection area 12 of the sensor 5, at the same time the outer detection area 11 of the sensor 4.
    The operating devices 7, 8 and 9 are designed so that they can set different illuminance levels of the lights 1, 2 and 3. For example, they have at least two or three different levels, so that in addition to the maximum illuminance, reduced illuminance can also be set. The maximum illuminance is referred to as the first illuminance, a lower illuminance as the second illuminance and an even lower illuminance as the third illuminance. It is of course not necessary for the first illuminance to be 100%.
    Coming back to the example, a person who enters the outer detection area 13 of the sensor 5 triggers the operation of the lamp 2. This is operated with the second lighting level, which is less than the first illuminance. If the person now moves further and, as described, enters the inner detection area 12 of the sensor 5, the lamp 2 is operated with its maximum illuminance or the first illuminance. At the same time, however, the person has now entered the outer detection area 11 of the sensor 4, so that the lamp 1 is operated here in a corresponding manner with the second illuminance. The second illuminance can be set to 30% of the maximum illuminance, for example.
    If the person goes on, they leave the inner detection area 12 of the sensor 5 and enter the outer detection area 13 of the sensor 5. At the same time, they enter the inner detection area 10 of the sensor 4. As a result, the first lamp 2 appears again the second illuminance is set and the lamp 1 is now set to the first illuminance, for example 100%.
    Upon entering the first detection area 10 of the sensor 4, however, the person simultaneously also enters the outer detection area 15 of the sensor 6. Accordingly, the lamp 3 is operated with the second illuminance. The further movement of the person then leads to the fact that the inner detection area 10 of the sensor 4 is left and when the outer detection area 11 is entered, the lamp 1 is set again to the dimmed value of e.g. 30%. When the person leaves the inner detection area 10 of the sensor 4, the person also leaves the outer detection area 13 of the sensor 5. The light 2 assigned to the sensor 5 is therefore switched off. At the same time, however, the person enters the inner detection area 14 of the sensor 6, so that the light 3 assigned to this sensor 6 is now raised to its maximum value.
    In FIG. 1 it can be seen that the boundaries of the detection areas are selected so that the inner detection area 10 of the sensor 4 lies completely in the outer detection area 13 and 15 of the adjacent sensors 5 and 6, respectively.
    At the same time, the inner detection areas 10, 12 and 14 touch each other, so that for a person who moves through all detection areas, one of the lights 1, 2 or 3 always works with its maximum illuminance. The inner detection areas 10, 12 and 14 can also be designed to partially overlap one another.
    In a preferred embodiment, the sensors 4, 5 and 6 are also equipped with communication means. A sensor 4, 5 or 6 can thus transmit an information signal to its neighboring sensors that a person is located in the outer detection area of the sensor sending the information signal. It is thus also possible, for example, to inform the neighboring sensor of a likely imminent movement before entering the outer detection area. In the exemplary embodiment described above, an information signal would be sent from the communication means of the sensor 5 to the corresponding communication means of the sensor 4 when a person entered the outer detection area 13 of the sensor 5 from the left. The sensor 4 receives the information signal and can forward a corresponding control signal to the operating device 7, which in turn can be distinguished from the output signals. The lamp 1 could then, for example, be set to a further reduced dimming value of, for example, 20% or a standby state of the sensor or the operating device. The information signal can be transmitted wirelessly or by wire.
    Alternatively, the sensors 4, 5, 6 can activate the lights 1, 2, 3 directly. The sensors 4, 5, 6 can have one or more switching elements and, depending on which detection area was triggered, the corresponding switching element can be activated and the associated illuminance can be set.
    In the figures, the ideal arrangement of the overlap of the detection areas of the sensors is shown. However, it is also conceivable that the detection areas do not extend that far
    overlap. In order to avoid unintentional light-dark switching in this case, provision can be made for a minimum operating time with the last set higher illuminance to be provided before a luminosity that has once been reached is reduced. This can prevent the lamp 1 from being switched off again when a person first enters the outer detection area 13 of the sensor 5 and a corresponding information signal is transmitted to the sensor 4 when entering the inner detection area 12 of the sensor 5. In this case, the operation of the lamp 1 is maintained via a time control. If the person then moves further to the right in FIG. 1, they will enter the outer detection area 13 when they leave the inner detection area 12, whereby an information signal is again transmitted to the sensor 4. Even if the person has not yet arrived in the outer detection area 11 of the sensor 4 at this point in time, this ensures that the room is continuously illuminated at least with the third illuminance.
    If the person then enters the outer detection area 11 of the sensor 4, the dimming value assigned to this outer detection area 11, that is to say the second illuminance, is of course regulated.
    It should be noted that the higher illuminance that is to be set due to an event has priority. In the event that several conditions are met at the same time, luminaire 1, 2 or 3 is always operated with the highest triggered lighting value.
    FIG. 3 once again illustrates the arrangement of the individual detection areas of the 3 sensors 4, 5 and 6 in a top view. Here, too, it can be clearly seen that the diameter of the first detection area 10, 12 and 14 of the sensors, which is round in the exemplary embodiment, corresponds to the width of the circular disk-shaped outer detection area 11, 13, 15 of the adjacent sensor.
