    SYSTEM FOR LOCATED LIGHTING CONTROL
    The invention relates to a system for spatially resolved lighting control. In particular, the invention relates to a system in which one or more motion sensors detect movements in a region and, depending thereon, drive at least one light source. The controlled light source is in particular designed such that, depending on the activation, a lighting for the area in which the movement was detected and / or a certain other area is activated or deactivated. The motion detector thus monitors a spatial position and detects a change in position. The at least one motion detector may also be a presence detector. In the following, the term motion detector is used synonymously. In the simplest case, at least two regions can be distinguished by a movement detector, that is to say whether a movement occurs in one of two regions and in which of the regions it occurs.
    A motion detector generally has a sensor that detects and detects movements in its environment and then outputs an electrical signal. In particular, a motion detector can be used as a switch that activates, for example, a light source when detecting a movement. This can be done by a controlled by the electrical signal relay. Such arrangements have long been known. A motion detector can also be used to activate an alarm signal. Motion detectors are known which are either active, e.g. with electromagnetic waves (eg. In the form of a Doppler radar) or work with ultrasound. On the other hand, passive motion detectors are known, e.g. detect an infrared radiation or an infrared radiation change. A combination of these techniques is also known.
    Passive motion detectors and in particular so-called PIR motion detectors (PIR = Passive Infra Red) which respond to changes in an emitted infrared radiation in the monitored area (for example heat radiation in the mid-infrared range at a wavelength of about 10 pm) are the most widespread here.
    Motion detectors thus detect a triggered by a movement signal passive or active. In this case, in front of the sensor of the motion detector, in particular in the focal distance of the sensor used, a substantially spherical or cylindrical cover can be provided with converging lenses, which is transparent in PIR motion detectors in the infrared range. The multiple lens collects infrared light from discrete directional sectors and focuses them on the sensor surface. Now moves an object or a living being, hereinafter generally referred to as object, with a surface temperature past the sensor or motion detector, which is sufficiently different from the background heat radiation / infrared radiation, the sensor can detect a temporal sequence of temperature changes and generate an electrical signal that is possibly amplified and output.
    Depending on the specific embodiment of the motion detector transverse or longitudinal movements can be detected or an approximation when the object to be detected from the perspective of the sensor, for. as an increasing surface as it approaches. In order to perceive a change in distance, ultrasound or Doppler radar sensors are also particularly suitable.
    As a presence detector motion detectors are generally referred to, which are superior and have a better resolution behavior. Thus, the presence detectors are more sensitive to changes in their environment (i.e., for example, brightness changes in the infrared region) and may also include other parameters such as ambient brightness to turn on illumination when certain thresholds are reached, for example.
    The aim of the invention is now to provide the possibility of detecting a spatially resolved motion information and / or to control a light source depending on a spatially resolved motion information. The light source is then controlled in particular so that a lighting for a particular area, for example in a room or in a corridor, is changed. In particular, the lighting is activated / deactivated for the area in which the movement was detected or which is indexed by the movement information output by the motion detector.
    To achieve this object, the invention provides a system, an apparatus, and a method according to the independent claims. Further developments of the invention are the subject of the dependent claims.
    In a first aspect, an illumination system is provided with at least one motion detector and at least one light source, wherein the motion detector has at least one sensor which is adapted to receive electromagnetic waves and / or sound waves and in terms of a spatial position or position change evaluate the reproducing parameter and to control the at least one light source depending on the parameter.
    The electromagnetic waves may be radio waves, heat radiation, in particular infrared radiation. The sound waves may in particular be ultrasonic waves.
    The motion detector may have an emitter for electromagnetic waves and / or sound waves. The sensor may be configured to detect electromagnetic waves and / or sound waves.
    The parameter may represent a distance or a change in distance of the motion detector to an object and / or an angle of incidence or a Einfallwinkelveränderung. In particular, it may define a direction and / or a spatial area in which a change in position has occurred.
    The light source may have at least two, preferably a plurality of bulbs and activate / deactivate individual or a group of bulbs depending on the parameter.
    The light source may be configured to emit light of various intensity, color, temperature, and / or other spatial direction, depending on the parameter.
    The motion detector can be a presence detector.
    The lighting system may have a plurality of light sources. The at least one motion detector can control individual light sources and / or light source groups depending on the parameter.
    The illumination system may comprise a plurality of motion detectors, and the lighting means of the at least one light source may be controlled by a plurality of motion detectors depending on the respective parameter.
    The at least one motion detector can control the at least one light source so that light source of the light source can be activated / deactivated, the emission direction correlate with the direction and / or a spatial region in which the change in position has occurred.
    In a further aspect, there is provided a motion detector comprising at least one sensor adapted to receive electromagnetic waves and / or sound waves and to distinguish the received waves with respect to their angle of incidence, the motion detector being functionally connected to a control unit, which is set up to determine a spatial position and / or a positional change from the different angles of incidence, and to output an output signal at an interface of the motion detector depending on the parameter and the detected angle of incidence.
    The motion detector can emit electromagnetic waves, in particular radio waves, and / or sound waves, in particular ultrasonic waves.
    The interface may be a bus interface and / or an interface for connecting a light source.
    In yet another aspect, a light source is provided with at least two light sources, in particular LEDs, which is adapted to activate / deactivate individual light sources and / or groups of light sources as a function of a signal received at an interface of the light source. In particular, a group may group together bulbs of one type or type, such as a color, color temperature, emission level, ....
    The light source may have a plurality of lighting means. The light sources at the light source can be divided into emission groups. A radiation group may at least partially comprise at least one group of activated / deactivated bulbs.
    The light sources of a radiation group can be designed in their arrangement on the light source and / or their type so that light of the associated light source is emitted substantially in one direction, intensity, temperature and / or color.
    The light source may have a control unit for evaluating the signal at the interface. The interface may be a bus interface and / or an interface for connecting a motion detector.
    The invention will now be described with reference to the figures: Figure 1 illustrates an example of a lighting system with motion detector and its function.
    Fig. 2 exemplifies an operation of the lighting system.
    Fig. 3 exemplifies a further operation of the Beleuchtungssys system.
    Fig. 4 shows schematically an embodiment of a light source.
    Fig. 5 shows schematically groupings of light sources of a light source.
    Fig. 6 shows schematically a further embodiment of a light source.
    Fig. 7 shows schematically an overview of the lighting system.
    The system according to the invention therefore has in particular at least one motion detector which outputs a spatially resolved motion information. This motion information can then be further processed either by a control unit of the motion detector to output a signal suitable for the system. The system thus evaluates at least one parameter representing a spatial position or a change in position. This parameter can be generated by the motion detector or after transmission of the electrical signal, e.g. be generated by a central control unit.
    Of course, it is also possible that the movement information of the motion detector is output to a control unit of the system or the light source, in particular a central control unit, which may be connected via a bus with the motion detector (DALI, DSI, ... - Bus).
    The control unit may be wired or wireless, e.g. be connected to the motion detector via radio or light.
    The corresponding movement information or the at least one parameter is then processed either by the motion detector itself, but in any case by the control unit and / or output to at least one light source, for example one or more lights.
    The control unit controls the at least one light source so that a certain area is illuminated, or the lighting is activated / deactivated or changed in a certain area. It can also be provided that depends on the
    Movement information other parameters of the at least one light source to be changed, for example, the degree of dimming, ie the brightness of the light emitted from the light source, but also for example the color temperature or color of the emitted light.
    The one or more light sources can be controlled depending on the spatially resolved motion signal to the effect that the lighting is activated / deactivated either for a current position and / or in an extrapolated in the future position of the detected movement triggering object.
    For example, the luminosity of the light source can be selectively increased to illuminate a certain area to a movement towards stronger or less strong. In this case, the luminosity can be changed in particular by selectively controlling different light sources or by activating different, fewer or more luminous means of a light source. In particular, the bulbs are LEDs. The light source is preferably designed so that an adaptive change in brightness is possible, which allows a purely electronic change in the emission characteristic, i. without mechanical change of the optics or the light source.
    Thus, for example, by means of a motion detector according to the invention and a light source according to the invention upon detection of a movement on an entrance door of a room specifically a lighting in the door area, or be changed and when detecting a movement and in particular the direction of movement targeted the further way of be moved moving object, for example, to point a path to an exit of the room. This consequently allows a kind of tracking (tracking) of the object triggering the movement.
    It should be understood that the above-mentioned control unit can also be arranged in the light source. In particular, the light source may be part of a light that is functionally connected to the motion detector. Thus, the motion detector can also be arranged in a luminaire, which then has an electronically adaptive emission characteristic.
    In integrating the motion detector into the luminaire, multiplexing is preferably performed in that the detection of reflected, visible or non-visible light (e.g., infrared) preferably occurs in PWM pauses in the operation of the illuminant associated with the luminaire.
    The sensor of the motion detector is preferably configured such that it evaluates an angle of a reflected radiation (for example an infrared radiation in an infrared sensor), ie an angle of incidence and in particular an angle of incidence change, and controls the light source as a function of this angle / angle change , As already mentioned, the light source can be an LED module. Accordingly, when using an ultrasonic motion detector, the sensor can evaluate the reflected sound accordingly. More specifically, the angle is evaluated in which the radiation or a sound from the sensor of the motion detector is accepted or hits on the sensor.
    The motion detector can thus, as stated, be mounted in a luminaire or in a luminaire arrangement, and evaluate an angle / an angle change of a reflected radiation or reflected sound waves and thereby detect a movement of an object.
    The motion detector can be connected via a bus with the lights of the lamp assembly, so at least one lamp, and control corresponding bulbs of the lights.
    The motion detector may be wired or wireless, e.g. be connected via radio or light to the lamp.
    The activated lighting means, which may be LED modules in particular, can be controlled in groups and activated depending on the position of the detected movement. Thus, for example, in a substantially linear arrangement of luminaires, the motion detector can detect an approach of the object due to the detected radiation / sound waves and, depending on this, activate individual luminaires or individual luminous means of the luminaires in order to activate / deactivate their color temperature and / or temperature To change color spectrum or to change the intensity of the emitted light (dimming).
    Further, it is possible that the at least one motion detector is coupled within a lamp with a plurality of light sources, so that depending on the movement of the detected object, a light source with at least one light source can be activated. The control can take place along or against a direction of movement of the detected object. For example, depending on the measured angle of the moving object, an LED module of the luminaire can be activated or deactivated.
    By way of example, such behavior is shown in FIG. A motion detector 1 is integrated in a luminaire arrangement 2. A moving object 3 moves into the detection area of the motion detector 1, so that it sends out a signal. From a control unit of the system (not shown), a light source of the light assembly 2 is then controlled so that an illumination 4 of the position of the object 3 takes place.
    If the object 3 continues to move and if the motion detector 1 detects a movement in another area, or if the detection angle changes, then another activation of the light source can take place or another light source can be driven to operate for the object 3 to provide another or additional illumination 4a at another position.
    In addition, it is possible to arrange several motion detectors and to connect them functionally with an array of light sources, eg. Lights. For example, the motion detectors may be arranged in the form of a matrix (at least two motion detectors) to detect movement of the object in space. Depending on an evaluation of the signals detected by the at least two motion sensors (for example a radiation intensity of the sensors of the motion detectors detected in the infrared range), it is then possible to determine the position of the moving object, e.g. done in the form of a triangulation. For example, here a sensor can already detect a movement that identifies an object that is relatively close to the first sensor, while the second motion detector or the sensor detects a signal that still indicates a greater distance to the sensor or the motion detector , In addition to a matrix arrangement, it should be understood that, of course, other arrangement patterns can also be selected, depending on how exactly a position of the object is to be determined.
    Fig. 2 shows schematically a corresponding arrangement and operation. A first motion detector 11 and a second motion detector 12 are arranged so that an evaluation of the received signals 13 allow a location of the object 14. In addition, a direction of movement 15 of the object 14 can be determined.
    In Fig. 2a, first, a first position of the object 14 is determined and correspondingly a light source (not shown) driven. Thus, the lighting in a first area 21 can be controlled. In this first area 21, then e.g. a dimming level of the emitted light to be changed, in particular, the light output can be increased by connecting light sources. Due to the determination of the direction of movement 15, a change in illumination in a second area 22 and a third area 23 can already take place. The region in which the current position is determined, is indicated in Fig. 2a by a solid line. The areas in which a change in illumination can (and does not have to) take place on the basis of the determined direction of movement are provided with a dotted border.
    If the object 14 continues to move as shown in FIG. 2b, a changed position can be detected by the motion detectors 11 and 12 and a change in illumination in the first to third areas 21-23 can take place correspondingly. For example, the illumination in the first area 21 can be deactivated, which is indicated by a dashed border. In the second area 22, in which the object 14 is currently detected, then, for example, a color change of the emitted light can take place (dotted area).
    Finally, Fig. 2c shows a situation in which the object 14 has changed its position again. The detected position now leads e.g. to a change in the illumination in at least the third area 23.
    The areas shown in Fig. 2 (first, second, and third area 21-23), in which the position of the object 14 is not determined, can be changed in their lighting. It should also be understood that a change in illumination, i. a corresponding activation of one or more light sources, even in at least one area, in which the position is not detected, e.g. in the first area 21 and the third area in Fig. 2a. The distance within which a motion detector detects a movement is usually in the range of 10 to 20 meters. It is further understood that the shape and arrangement of the regions 21-23 may differ.
    Fig. 3 shows a matrix arrangement of motion detectors 31, which may be of the same or different type. The motion detectors 31 can then be used to move an object 14 along a path 32, e.g. to guide an obstacle 33. Thus, regions 34 along the path 32 may be in a manner, e.g. are illuminated with a light color (e.g., green) while, if a position of the object 14 is detected in an area 35 outside the path, those areas may be illuminated differently (e.g., red).
    If an infrared sensor is to be used together with an ultrasonic sensor in a motion detector, or only an ultrasonic sensor in the motion detector used so it is possible to attach the sensor to one end of a light source assembly or lamp assembly, which is aligned substantially linearly , Since ultrasonic sensors are particularly well suited for distance measurement, then depending on the distance of the moving object to the motion detector individual light sources / light sources of the arrangement can be activated / deactivated. It goes without saying that an activation or deactivation of lamps can also take place at the same time.
    Thus, for example, depending on the movement of the moving object and the movement information output by the motion detector at least one light source or a group of light sources, each having at least one light source are activated, while other light sources deactivated or in their behavior by changes in operating parameters be changed accordingly (color change, brightness change, color temperature change, ...).
    In particular, the invention thus makes it possible to provide illumination in which only the area (not) is illuminated in each case by the moving object being located. On the other hand, it is also possible to illuminate certain areas depending on a detected motion vector. For example, the control unit can determine a direction of movement on the basis of various movement information. In one embodiment, it is then possible, for example, to emphasize danger areas that lie in the path of movement of the moving object by means of corresponding illumination (red illumination) and thus make them recognizable. The same can of course be done by a color change, which is performed by the corresponding light source or light sources.
    As illustrated in FIG. 4, the light source can have a substantially convex carrier element 41, on which at least one light-emitting means 42, but preferably at least two light-emitting means 42, are arranged. The bulbs are in particular LED modules or LED chips. These individual modules or chips are then selectively controllable, as a result of which different emission characteristics can be set. For example, if one LED module / chip is disposed on the convex support member while the other module / chip is disposed opposite to the support member, then one of three radiation modes may be set in which either the first chip / first LED array Module, the second chip / the second LED module, or both chips / LED modules are activated or deactivated.
    The individual lamps or LED chips / modules can also be divided into groups, wherein an LED converter can be provided for each group. Depending on the motion information of the motion detector (s), groups of light sources can then be switched on and off and a corresponding radiation characteristic can thus be generated.
    FIGS. 5a and 5b show an example of how lighting means of the light source can be grouped together. FIG. 5a shows a plan view of a light source with an essentially star-shaped arrangement of light sources, of which a first group 51, a second group 52, a third group 53 and a fourth group (remaining lamps) are then formed according to the drawn lines. These groups can then also be operated individually or in combinations.
    FIG. 5b shows a further example of an essentially matrix-like arrangement of light sources, which can likewise be combined to form groups 54, 55, as indicated by the drawn lines.
    It is also possible to combine / divide the groups into / into broadcast groups, which are then activated / deactivated.
    As shown in Fig. 6, alternative embodiments of the light source with a substantially planar support 61 are possible. The lighting means 62, which may correspond to those of FIG. 4, are here mounted with different inclinations on the carrier 61. Thus, upon activation of the lighting means or radiation groups of light sources of the light source different emission characteristics can be generated.
    Alternatively, substantially prismatic and / or trapezoidal light-directing means can be attached to the lighting means. The lighting means can then be arranged on the carrier and the emission characteristic can be generated by directing / deflecting the light emitted by the lighting means. Alternatively or additionally, lenses or a multiple lens may be mounted in front of the light sources so as to direct emitted light in desired directions. The lens (s) may be movable with respect to the carrier. Thus, for example, even when the LED chips / modules are arranged on a substantially planar carrier, the emission characteristic of the light source can be changed.
    A corresponding control can be done for example by means of DALI command via a bus. As described, a corresponding command can be received by a control unit external to the light source, or a corresponding evaluation can be carried out by a control unit of the light source.
    In particular, bus commands that are part of a scene lighting setting can be evaluated.
    A light source, as described above, can also evaluate control signals of several motion detectors. Thus, at least one illuminant / group / Abstrahlgrup-pe of light sources of the light source can be activated / deactivated when a signal from a motion detector has been issued, while another illuminant / another group of bulbs is activated / deactivated when a signal from a other motion detector is output. In particular, when the light source receives a corresponding command via its interface.
    Fig. 7 shows a schematic overview of the lighting system according to the invention. Therein, two motion detectors 71, 72 are shown by way of example (the system has at least one motion detector), each of which has an interface 71s, 72s. The motion detectors 71, 72 are configured to receive electromagnetic waves and / or sound waves (represented by arrows) and to evaluate them in terms of a parameter representing a spatial position or positional change.
    This evaluation can be done either in the motion detectors 71, 72. Alternatively or additionally, however, corresponding information can be transmitted via the respective interface 71s, 72s and a bus to a central control unit 73, which then takes over the evaluation. The central control unit 73 has interfaces 73s1 and 73s2 with which it can be connected either directly to a motion detector / light source or to a bus. The motion detectors may control the at least one light source 74, 75 depending on the parameter. Alternatively or additionally, the control can take place via the central control unit 73.
    Alternatively, the communication between the motion detector and the control unit takes place wirelessly, e.g. over radio or light.
    For receiving corresponding drive information, the at least one light source 74, 75 has an interface 74s, 75s.
    The parameter represents a distance or a distance change of the motion detector to an object and / or an angle of incidence or an angle of incidence change, and in particular defines a direction and / or a spatial area in which a change in position has occurred.
    Of course, the interface of the respective motion detector or of the respective light source can also be configured differently, e.g. as USB, Bluetooth, Wlan, Zigbee, ... interface.
