Definitions

  • the present invention relates to a lamp or lighting arrangement with a plurality of lighting modules or lighting segments, wherein the lighting modules are thermally coupled to each other and each having a temperature sensor and wherein the lamp is adapted to determine the position of each lighting module within the lamp and each lighting module in dependence assign an address to the position.
  • Such lights can, for example, be elongated, wherein the lighting modules are then arranged linearly or one behind the other.
  • the light-emitting modules are controllable modules, for example LED modules, which can be controlled or set individually or independently of each other, wherein the light modules are usually connected to a parallel bus.
  • each light module can be individually addressed or contacted, for example by a central control device, which is also connected to the bus, and accordingly each light module must have an address.
  • the position of the individual lighting modules is known in relation to their address.
  • the address assignment to the lighting modules can, for example, be made before the installation of the lighting modules or even during the production of the lighting modules. By doing so, however, the problem arises that each light module must be installed exactly at the position within the lamp, which was previously determined by the address, otherwise the corresponding address of the light module is assigned to a wrong position in the lamp.
  • each luminaire module is assigned an address manually after the installation of all the luminaire modules in the luminaire. This can, for example. At an elongated light to a light module at the edge of the lamp the address 001 be assigned and then the other light modules of the light in sequence with ascending addresses 002, 003, etc. are provided, whereby a central control device automatically the position of the corresponding light module known due to the address is.
  • this procedure involves considerable effort during or after the installation and, on the other hand, that manual errors can also lead to operator errors, which in turn lead to incorrect activation of the Lead light modules.
  • the lighting modules are cabled in series within the luminaire and thus corresponding addressing or position detection results automatically.
  • additional bridging measures for example a relay for bridging a defective board, are required.
  • the present invention is based on the object to develop a lamp with an alternative addressing of the lighting modules, in which a simple and error-free addressing of the lighting modules is possible and even in the event of an error, no appropriate bridging measures are required.
  • these modules have a temperature sensor which serves to detect an over-temperature condition within the lighting module and, if necessary, to switch off the lighting module To avoid damage.
  • this temperature sensor is now also used for determining the position of the lighting modules within the luminaire.
  • the luminaire modules are therefore thermally coupled to one another and each have a temperature sensor, and wherein the luminaire is designed to determine the position of each luminous module within the luminaire and each luminous module in Dependence of the position to assign an address.
  • the temperature in the luminous modules is in each case determined with the aid of the temperature sensor and with the aid of this information the position of the respective luminous module within the luminaire is determined.
  • the temperature values determined by the temperature sensors are thus used not only to avoid damage in the event of an overtemperature, but additionally also to determine the position of each luminous module within the luminaire, whereby it is then possible for each luminous module by the exact position determination a corresponding address will be assigned.
  • the luminaire has a central control device for determining the position of the luminous modules and for assigning addresses, or that one luminous module or a plurality of luminous modules is / are designed to determine the position of the luminous modules and assign an address to each luminous module.
  • the luminaire In order to determine the position of the lighting modules, the luminaire preferably determines the temperature values for all luminous modules of the luminaire and determines the position of each luminous module on the basis of the resulting temperature profile or the different high temperature values. It can be provided that the lamp shuts off all lighting modules before determining the position of the lighting modules.
  • the luminaire does not determine the position of the luminous modules until the temperature values of the luminous modules measured by the temperature sensors are below a threshold value.
  • the light In order to determine the position of the lighting modules, it is then also possible for the light to switch on a light module arranged at the edge of the light, wherein prior to switching on the light module arranged at the edge of the light, it has been known or determined which light module is on the edge the lamp is arranged. This determination can be made by a device, for example. A jumper, wherein at least one of the lighting modules can have such a device. Alternatively, it can also be provided that one lighting module has poorer thermal properties than the others and is arranged on the edge of the luminaire or in the vicinity of other heat sources, such as electronic ballasts.
  • the luminaire switches on all the luminous modules simultaneously before determining the position of the luminous modules and before switching off all the luminous modules and determines the luminous module with the highest measured temperature value as the luminous module arranged at the edge of the luminaire.
  • the luminaire determines the position of the luminous modules based on the falling temperature values in order to determine the position of the luminous modules, such that the luminous module has the highest measured temperature value the switched-on lighting module is, the lighting module with the second highest measured temperature value is the first switched off light module arranged directly next to the switched-on lighting module, the lighting module with the third highest measured temperature value is the second switched-off lighting module arranged directly next to the first switched-off lighting module, etc.
  • each luminous module is switched on one after the other, starting with the luminous module having the second highest measured temperature value, and after each switching on of a luminous module, the temperature values of the luminous modules are determined again.
  • the position of the lighting modules preferably results as described above, and the temperature values of the lighting modules which have been switched on before the last-connected lighting module are ignored.
  • the light module is switched off before the last switched on light module.
  • the temperature sensors are asymmetrical, i. not centered, are arranged within the lighting modules.
  • the temperature sensors With an asymmetrical arrangement of the temperature sensors, it is then also possible to determine the position of the lighting modules within the luminaire when no luminous module arranged at the edge of the luminaire is known and can not be fixed. In this case, it is then advantageously provided that for determining the position of the lighting modules, the light switches on a randomly selected lighting module.
  • the luminaire determines the relative position of the other lighting modules relative to the switched-on lighting module on the basis of the falling temperature values, such that the lighting module with the highest measured temperature value is the switched-on lighting module, the lighting module with the second highest measured temperature value directly to the left or right next to the switched-on Luminous module arranged first light module is switched off, the light module with the third highest measured temperature value is directly to the right or left of the switched light module arranged second switched off light module, etc., depending on the asymmetric arrangement of the temperature sensors, the first light module switched off to the left and the second light module off right or the first light module switched off to the right and the second light module switched off to the left of the switched-on light module are arranged.
  • the luminaire can then determine the absolute positions of the luminous modules within the luminaire on the basis of all relative positions.
  • thermo models are stored in the luminaire and, for determining the position of the luminous modules, the luminaire compares the stored temperature profiles with the resulting temperature profile.
  • the luminaire briefly switches on the luminous modules for generating a thermal pulse for determining the position of the luminous modules and takes into account the temporal temperature profile when determining the position.
  • the lamp may be elongated, wherein the lighting modules are then arranged linearly or one behind the other in the lamp. Likewise, the lighting modules could also be arranged in the form of a matrix in the luminaire.
  • FIG. 1 schematically a luminaire or lighting arrangement 1 according to the invention is shown, which has a plurality of lighting modules or lighting segments 2.
  • the lamp 1 is configured elongated, wherein the lighting modules 2 are arranged linearly or one behind the other, so that an arrangement results in series.
  • four light modules 2 are provided in the luminaire 1, which are labeled with the letter AD for later detailed explanation of the position determination and address assignment.
  • each lighting module 2 is connected via a bus 4 to a central control device 5.
  • This central control device 5 is provided on the one hand to control the individual lighting modules 2 individually and independently of each other.
  • the central control device 5 but also the position of each light module 2 is determined within the lamp 1 and assigned a corresponding address based on the position.
  • each light module 2 has a temperature sensor 3.
  • this temperature sensor 3 was merely used to measure and detect an excess temperature and, if necessary, to switch off the corresponding lighting module 2 in order to avoid damage, which is important, for example, if the lighting modules 2 are configured as LED modules.
  • the temperature in each case is determined in the lighting modules 2 with the aid of the temperature sensors 3 and transmitted to the central control device 5 via the bus 4.
  • the central control device 5 can then determine the position of the light modules 2 within the light 1 on the basis of the transmitted temperature values of the individual light modules 2.
  • the lighting modules 2 are thermally coupled to one another, which is however usually provided in such luminaires 1.
  • the thermal coupling then ensures that the heat of a switched-on lighting module 2 is transmitted to the adjacent lighting modules 2, it being noted that the temperature or heat is not evenly distributed to all lighting modules, but is transmitted depending on how far a lighting module 2 is removed in each case from the heat-generating switched-on lighting module 2. This then results in a temperature profile or results in different temperature values for the individual lighting modules 2, as a result of which the position of the respective lighting module 2 with respect to the heat-generating lighting module 2 switched on can be determined.
  • a arranged on the edge of the lamp 1 lighting module 2 is already known or determined prior to determining the position of the lighting modules.
  • FIG. 1 could be, for example, the lighting modules A or D.
  • a manual determination can take place, for example, by a jumper, which has at least one of the light modules 2 arranged on the edge.
  • An alternative possibility to set the edge position of a light module 2 is that one of the modules 2 has poorer thermal properties than the other light modules 2 and then arranged on the edge of the lamp 1 or that automatically by the positioning of the light modules 2 at the edge of the lamp 1 worse thermal properties for this result, in which case additionally should be provided that, for example, the light module A has even worse properties than the light module D due to the position in the lamp 1. This could, for example, be achieved by a corresponding construction within the luminaire 1.
  • all luminous modules 2 are switched on at the same time and then the luminous module 2 is set with the highest measured temperature value as the luminous module A or D arranged at the edge of the luminaire. It may u.U. make sense that after the simultaneous turning on all lighting modules 2 a certain time to heat up the lighting modules 2 is waiting, as in the event that, for example, previously switched on some lighting modules 2 and others were turned off, only after a certain heat-up the light module 2 with the worst thermal properties also has the highest measured temperature value.
  • a light module 2 After a light module 2 has been set as arranged at the edge light module A and D, by a jumper or worse thermal properties, it is provided that all lighting modules 2 are turned off. To ensure that no temperature values are measured that lead to incorrect position determinations lead after switching off the lighting modules 2 also also be provided that the lighting modules 2 remain off for a certain time to ensure that the temperature of all lighting modules 2 is below a certain threshold or within a certain range and thus more or less, a static off state of the lighting modules 2 is achieved.
  • the luminous module 2 arranged at the edge is turned on.
  • this is either the light module A or the light module D, wherein in the following example, the light module A is used. After the light module A has been turned on, it is still possible to wait a bit until a certain heating is achieved.
  • a temperature value is then determined in each light module 2 with the aid of the temperature sensors 3.
  • the switched on lighting module A itself has the highest measured temperature value.
  • the central control device 5 possible to assign the lighting modules 2 corresponding addresses, wherein in FIG. 1 is provided that the light module A, the address 001, the light module B, the address 002, the light module C, the address 003 and the light module D receives the address 004, which already results from the address, the position of the light modules 2 within the lamp 1.
  • each lighting module 2 is switched on one after the other, with the temperature values of the lighting modules 2 being determined again every time a lighting module 2 is switched on. This results in each new measurement further temperature values that give a more accurate picture of the positions of the individual lighting modules 2.
  • the lamp 1 in FIG. 1 For example, it would be provided that, after switching on the light module A and a first temperature measurement in all light modules 2, the light module B is turned on and again the temperature values are measured at all light modules 2, etc . Then, the positions of the light modules arise comparable As already described above, the temperature values of the lighting modules 2 that have been switched on before the last-connected lighting module 2 are disregarded.
  • the lighting module 2 is switched off before the last switched on lighting module 2.
  • the light module A would be turned off after the light module B has been turned on, wherein only after switching off the light module A, the further temperature measurement would be made.
  • FIGS. 2 and 3 in each case a lighting module 2 and 12 is shown, wherein in the lighting module 2 in FIG. 2 the temperature sensor 3 is arranged centrally in the light module, as in FIG. 1 is shown. In contrast, in the lighting module 12 in FIG. 3 the temperature sensor 3 is arranged asymmetrically, that is, the temperature sensor 3 is placed outside the center.
  • FIG. 3 shown light module 12 could also in the lamp 1 in FIG. 1 Application, wherein the asymmetrical arrangement of the temperature sensor 3 is particularly advantageous in a second embodiment of the invention, in which no arranged at the edge light module 12 is known or could be set, as different temperature values for the left or right of a turned on by the asymmetric arrangement Light module 12 arranged light modules 12 result.
  • the lamp 1 in FIG. 1 would correspond to the asymmetric arrangement of the temperature sensors 3 FIG. 3 in a switched on light module B different temperature values for the switched off lighting modules A and C result, in detail, light module C would have a higher temperature value than light module A, since the temperature sensor 3 of the light module C would be located closer to the light module B than the temperature sensor 3 of the light module A and thus more heat would get transferred from the light module B.
  • This asymmetrical arrangement of the temperature sensors 3 thus makes it possible to distinguish whether a respective lighting module 12 is arranged to the left or to the right of a lighting module 12 that is switched on.
  • the randomly selected lighting module 12 is the lighting module B and accordingly the lighting module B is switched on.
  • the light module B then has the highest measured temperature value.
  • the luminous module C then has the second highest measured temperature value due to the asymmetrical arrangement of the temperature sensors 3, the luminous module A the third highest measured temperature value and the luminous module D the fourth highest measured temperature value, since the temperature sensor 3 of the luminous module D despite the asymmetrical arrangement is further away from the light module B than the temperature sensor A of the light module A. This then results in the relative position of the different light modules A, C and D to the light module B.
  • the switched-on lighting module 12 is turned off and the other lighting modules 12 and switched off and off and the relative position of the switched-off lighting modules 12 relative to the switched-on lighting module 12 by means of the falling Temperature values determined.

  • the light module D would be switched off and successively still the light modules C and A or A and C on and off.
  • the absolute position of each lighting module 12 can then be determined by the combination of all relative positions and by appropriate sorting.
  • the lighting module is only switched on briefly in order to generate a thermal pulse and to take into account the temporal temperature profile when determining the position.
  • reference measurements can be carried out, for example, during the production of the luminaires or luminous modules in order to describe the thermal propagation within the framework of a thermal model or a temperature profile.
  • These thermal models or temperature profiles can be stored in the luminaire and correspondingly taken into account in the later measurements for determining the position, it also being possible to carry out a pausibility check as to whether the then measured temperature values are realistic or not.
  • It can also be determined whether or below which threshold value the temperatures should fall before a corresponding determination of the position can be carried out.
  • a central controller 5 performs the determination of the position and the address assignment.
