    "Method of controlling the light distribution of a luminaire"
    The present invention relates to a method for controlling the light distribution of a luminaire, in particular a street luminaire of a luminaire network which is also preferably organized as a mesh network, the luminaire having a luminaire head comprising an adjustable light module and a controller and the light distribution being variable. The invention further relates to a luminaire for implementing a corresponding method and a network of luminaires.
    Street luminaires are luminaires that are installed alongside roads, cycle paths, pedestrian paths or, for example, in pedestrian areas. They may be luminaires which, by means of a mat anchored in the ground, are placed at a distance from the latter or which are suspended in the middle, for example between house facades above taxiways. .
    Producers of luminaires, in particular street luminaires, offer luminaire network operators a plurality of light modules which achieve a desired light distribution of the associated luminaire. This light distribution is obtained for example by an orientation of the LED lenses or reflectors. The light module with its lighting means, reflectors and possibly housing parts can achieve a desired light distribution via the radiation direction of the individual LEDs.
    When replacing defective lighting or a defective light module or a defective luminaire, the same luminaire must therefore be produced with the special settings of the reflectors, lenses, etc. This requires extensive storage.
    The object of the present invention is to reduce storage costs and to configure more usable luminaires.
    The object is achieved by a method according to claim 1. The object is further achieved by a luminaire according to claim 22 and an array of luminaires according to claim 25. Advantageous configurations of the invention are apparent from the subclaims as well as the following description.
    According to the invention, it is provided that the luminaire transmits to a server data specific to the luminaire and in particular relating to the installation location of the luminaire, after which data for a distribution of the light is attributed to the luminaire and an adjustment of the luminaire. Luminous module is automatically based on the data. The adjustability of the light module is due to adjustment means which will be described below. The operator of the luminaire receives on the basis of the method according to the invention which can be determined either automatically or manually on the server side the shape that must take the light distribution of a luminaire. Then data is automatically supplied to the luminaire for its light distribution after its contact (activated by the controller). On the lighting side, the controller then preferably automatically monitors, on the basis of the data, an adjustment of the light module. The assignment of data for a light distribution (light distribution data) is subject to a specific identification of the luminaire and in particular to geolocation information relating to the installation location of the luminaire that can be transmitted to the server.
    By luminaire is meant in particular a street light for which a luminaire head is disposed on a luminaire mast. The luminaire head can also be positioned without a light pole on a house wall or in the middle between house walls. In the luminaire head there is a luminous module which can be adjusted so that the light distribution of the luminaire can be varied, in particular by means of adjustment means, possibly also by the switching on and off of groups. individual lighting means having a different radiation characteristic than the one already engaged.
    The light distribution results from the radiation characteristic of the light module, that is to say the light coming out of the luminaire or the light module at a given angle and / or its intensity. Bridge also part of the light module, in addition to the lighting means, the lenses associated therewith and optionally reflectors to the extent that they are adjustable and which can also be formed at least in part by the housing of the luminaire head.
    The controller is a control module which is disposed either inside the housing of the luminaire head or on the luminaire housing, transmits control signals for controlling the luminaire light and is further responsible in particular for the communication with the server or other members of a lighting group. There are also controllers that can additionally process sensor information. These can also be used in an improvement of the invention to change the radiation characteristic Communication within the network not only towards the server but also with other possible luminaires can also take place via of the controller.
    The server is either a server accessible by long-distance communication or also by internal paths of the network, this server possibly being kept available via the Internet. A remote management system that runs, for example, on the server is responsible. control of a luminaire network and can be controlled by the network operator.
    The network server can also be represented by several servers, for example a first set of information data luminaires sent to a first server, the corresponding information for the light distribution of the luminaire is then transmitted by another server. It can, for example, be a connection server that only sets the assignment to a corresponding project server. The project server is then responsible for communication with the luminaire controller and therefore with the luminaire and provides the luminaire with the necessary information for its operation, in particular for the light distribution and therefore for the adjustment of the module. luminous. Instead of geo-location data, data based on GPS, data from other navigation systems such as Galileo, Glonass or Beidou can of course also be used.
    A light distribution class resulting from the position of the luminaire and also transmitted location data is assigned to the luminaire on the server side. Different significant light distributions which can be achieved for example on roads and which can correspond to a determined radiation characteristic of a luminaire are defined beforehand so as to be able to proceed thus to a simple and fast assignment of the luminaires to individual classes. This results in a certain standardization and a simpler observation according to the communication channel to be illuminated.
    The light distribution class is preferably determined on the basis of a road topology. The road topology is based, for example, on a road situation, the type of road (for example, main road, secondary road, crossroads, roundabout, parking area, one-way road) and / or an association of roads. or road areas with required light distributions and / or the disposition (especially the deviation) of light spots along the road. Legal requirements can also be taken into account. In addition to roads for motor vehicles, communication routes for other road users can also be taken into account.
    By road topology, we therefore mean the frame of the communication channels which is also, for example, at the base of the navigation systems, which provides for example information on the traffic lanes, the width of the roads or paths. and possibly also the traffic density dependent or not time. Depending on the situation of the road network or the communication route or a road zone, a light distribution that must be reached by a luminaire or a plurality of luminaires positioned at the edge of or on the communication channel is defined for this area. The aim here is to provide the necessary lighting for the communication route and to make it suitable for traffic.
    The light distribution to be made by the luminaires is also determined in particular by the spatial arrangement of the luminous points with respect to each other and along the topology of roads. For example, a street luminaire must illuminate only part of the traffic lane when a street light is also on the opposite side of the road.
    The corresponding data bank for the topology of roads can be present locally or be also based on the web.
    Therefore, after considering this for the luminaire and the luminous point thus formed, a corresponding traffic lane has been identified or has been associated with this luminaire, the corresponding information for the luminaire results from the associated light distribution for the luminaires. light distribution classes.
    The following is a simplified description of roads or road lights, and here it may be generally of lanes or traffic areas of any kind.
    Advantageously, the light module has a plurality of LEDs which are divided into different groups to achieve the desired light distributions. The maximum number of groups results from the maximum number of LEDs, especially when each LED is distributed in a group of its own.
    Typically, however, several LEDs are brought together in a group to achieve a significant change in the radiation characteristic by their fit, when the entire group is moved, their lenses move and / or the associated reflectors are moved and, for example, the luminous flux of individual groups or of several groups is increased.
    Alternatively or in addition, the light module can be formed based on OLED which are divided into different groups to achieve the desired light distribution. A lighting surface formed of OLED can be subdivided into different zones by dividing it into several separately controllable groups. It is also possible to divide several OLED-based lighting surfaces in a light module into different corresponding groups.
    According to the invention, the controller can present a data set with an assignment of different light distributions for the necessary adjustments of the groups for this purpose. Here, the necessary parameter sets by which the control of the adjustment means of the respective groups is determined are for example recorded in tabular form. These parameters are therefore recorded according to the respective setting means of the groups.
    Advantageously, the controller orders adjustment of the groups and the individual groups can be controlled by a bus system or by separate control outputs of the controller,
    The transmission of the light distribution data can take place during or spaced apart in time after the first commissioning of the luminaire. Thus it is possible for example to already provide the controller directly during its first installation or its · first commissioning a set of parameters for (the class of) the distribution of light.
    For example, when the controller first connects to a server or servers and transmits location data and other reference data that specifies the fixture, it will be known in the server system and therefore on the system side. remote management. A light distribution and possibly a light distribution class are assigned to the luminaire which must realize them, there can also be transmission, in a communication between server and controller by which the integration of the luminaire in an associated mesh network can be triggered and which is thus necessary for the first commissioning, information on the class of light distribution, after which the luminaire triggered by the controller correspondingly directs the light module or its groups.
    Alternatively or in addition, there may be transmission on the server side, spaced apart in time after the first commissioning of the luminaire, for example to achieve a modified lighting situation and therefore a new assignment to a distribution class of light, of a signa! corresponding to the luminaire so that it changes its light distribution and its radiation characteristic This can also be done dynamically according to traffic information determined or the density of road users or dynamically during of a day.
    Light distribution data transmission with expanded radiation compared to a previous projection can take place automatically or manually, in particular depending on a failure of a neighboring luminaire. The failure of a street light can thus be at least partly compensated by nearby street lights because neighboring luminaires broaden their transmission, which significantly increases the operational safety of the illuminated communication channel. Such Indication may also occur manually as a result of a failure signal so that the operator can decide on a case-by-case basis whether neighboring luminaires are receiving or which neighboring luminaires are receiving a new radiation characteristic.
    It is also advantageous if the allocation of the light distribution performed on the server side can be manually overwritten or changed for a luminaire so that a correct light distribution or light distribution class can be attributed to a luminaire which receives no light. no attribution or received an erroneous attribution. For this purpose, the associated remote management system has appropriate control means, for example corresponding GUIs on the server side.
    According to another embodiment of the invention, the orientation and / or shape of LED printed circuit boards (PCBs) can be varied to adjust the light distribution. Alternatively or additionally, the orientation and / or the shape of the lenses associated with the LEDs can be modified to adjust the light distribution, electroactive polymers or other active substances reacting to the application of a voltage can by example be used for this purpose.
    Alternatively or additionally, the orientation and / or shape of the reflectors associated with the LEDs can also be modified to adjust the light distribution. Associated control means for the prescribed orientation and shape of LED printed circuit boards or lenses and / or reflectors may be, for example, electric drive motors which have a wax-based drive, it may these are ultrasonic motors similar to the modulation of the focal length in the camera lenses or the aforementioned synthetic substances.
    A luminaire according to the invention serving to achieve the purpose mentioned at the beginning, besides the communication means and the electronic data processing means (controller) necessary, corresponding control means.
    The purpose described above is also achieved by a luminaire for implementing the method indicated above or described below, the luminaire having a plurality of LEDs or one or more OLEDs and the radiation angle of the light from the LEDs or OLEDs that can be modified by order of a luminaire controller (and associated control means).
    The same applies to a luminaire network which has a plurality of luminaires described above, one or more servers and means of communication of the luminaries between them and / or with the server being present. On the server (s) itself, there is software that presents databases and associated programs for the operation of the network. Other advantages and details of the invention emerge from the description of the figures which follows. The schematic representations of the figures show on: FIG. 1 a topology of roads with individual luminaires, fig. 2 classes of light distribution, FIG. 3 a street light in a partial view from below, FIG. 4 parts of the object according to FIG. 3 in different modes of operation, FIG. Another embodiment of a street light according to the invention in one. partial view from below, fig. 6 parts of the object according to Fig. 5 in different modes of operation, FIG. 7 a lighting situation on a road, fig. 8 another lighting situation on the road according to fig.7.
    Individual technical features of the exemplary embodiments described hereinafter can also, in combination with embodiments described above as well as with the features of the independent claims and any other claims, be combined into objects according to the invention. . As far as useful, elements operating in a functionally equal manner are provided with identical reference numbers.
    To implement a method according to the invention, an illustration of the topology of roads with associated light points which each correspond to a luminaire is formed, according to the first example of embodiment, starting from luminaire information relating to the location of the luminaire. installation of luminaires. A view of such a topology with associated luminaires 1 is shown in FIG. 1, Starting from the coordinates of place transmitted by the luminaires, which thus represent luminaire data relating to the place of installation of the luminaire, luminaires 1 are integrated in the topology of roads. The route topology, which can be retrieved, for example, from data banks on the Internet or in a database of its own or that can be found in the server, presents a plurality of routes and characterizes them unequivocally. For example, a road 2 is a busy road, a road 3 is a road link, a road loop is a roundabout 4 and a road 5 is a road. access to a parking area 6. Further information on roads can be extracted from the topology of roads, for example to what extent it is a multi-lane road, possibly how wide is it they are one-way roads or, for example, residential areas. The spatial allocation of the luminous points or luminaires 1 to the respective routes takes place for example by means of a distance function. Thanks to the knowledge of the light classes that are associated with the respective roads, the lighting distribution or the light distribution class required for the luminaire concerned is obtained, taking into account the distance of the luminaires from one another. Correspondingly, light distribution classes, as shown by way of example in FIGS. 2a to e) can be associated with the luminaires. Thus, for example, it is necessary to operate the luminaire 1 disposed on the narrow road 5 which is designed as a one-way road and serves as access to the parking area with a light distribution according to the fig. 2b) (light distribution class II), while a luminaire 1 located in the middle of the roundabout (road 4) is to be classified in the light distribution according to fig. 2e) (light distribution class V). The luminaires 1 arranged along the main road 2 are for example characterized by the light distribution according to FIG. 2d) (light distribution class IV).
    In addition to the classification according to fig. 2, other light distribution classes can be defined based on the situation or values based on experience, these classes representing wider light distributions. The respective light distributions result from the radiation characteristics of a luminaire 1 arranged with respect to a road 7 shown schematically, an enveloping 8 representing itself as a transition of an irradiated surface with a determined luminosity, the surface being illuminated by the luminaire 1 , to an environment. The enveloping 8 essentially results from the radiation angle of the light emerging from the light module of a luminaire 1.
    According to the embodiment of FIG. 3, such a light module 9 has in total in the present embodiment eight groups 11 of two LEDs 12 each. The LED groups 11, which can also respectively represent a clean circuit board, are laterally delimited by reflectors 13 through which the emergence of light can further be influenced.
    After assigning a light distribution class by the server and corresponding instructions in the controller, the groups 11, as shown in vertical section IV-IV (FIG 4), can rotate from their shown position in fig. 4a) in the predefined position according to FIG. 4b). The arrows 14 show the direction of movement of the different groups of LEDs that are pivoted motorically by a control means around a pivot axis (not shown).
    According to the embodiment of FIG. 5, a light module 9 is produced according to the invention, which adjusts the lighting means of the groups 11 and thus to the variations of the radiation angle not or not only by a variation of the orientation of all groups 11 including printed circuit boards at their base, but for which the orientation takes place via lenses 16 to the adaptable form.
    The lenses thus pass from a basic position with, for example, a semicircle shape according to FIG. 6a) (section VI-VI according to Fig. 5) to a lens shape determined according to the desired radiation characteristic, for example as an elliptical paraboloid cut obliquely according to Fig. 5a. 6b). For this purpose, it is possible in particular to use electroactive polymers having a sufficient thermal resistance.
    Alternatively or in addition, it is possible to cause additional changes in the radiation characteristic by adjusting the orientation of the printed circuit boards 15 or any reflectors 13.
    For sufficient illumination, for example, depending on the route topology and the light distribution class, an adjustment according to FIG. 7 in which a radiation angle α of a luminaire 1 - seen in the plane of the figure - which is designed as street luminaire, is about 70 °. A road 3 is thus sufficiently illuminated. In the case where the central luminaire shown in FIG. 7 breaks down and where we know it by a signa! corresponding to a server of an associated remote management system or the network of luminaires 1, it can be given automatically instruction to the luminaires 1 neighbors to adapt the distribution of light, to ensure sufficient illumination of the road despite the breakdown. The opening angles of the radiation are changed towards the luminaire of the medium so that the two adjacent luminaires 1 have a radiation angle α of about more than 90 ° seen in the plane of the figure. In addition, the luminous flux towards the luminaire of the medium can be increased.
