    The present invention relates to a light rail system according to the preamble of claim 1.
    Light rail systems generally comprise a base rail with electrical power supply lines and a number of base rail attachable lights which are powered by the power supply lines with electric power. Light rail systems are versatile and are particularly suitable for illuminating goods in shop windows or presentation shelves and the like Variety of lights is provided in the light rail system, goods can be selectively illuminated by individual lights and thus visually prominently presented.
    However, it has been shown that the desired effect of highlighting individual goods often does not bring the desired positive result. A reason for that is. that the goods mostly have different colors, whereas the lights uniform Leuchtmittc! have. Therefore, when the goods are irradiated, the desired color reproduction values are not obtained and the goods appear pale, unsightly, or distorted in color. The color rendering value expresses how "real" the colors of objects look to the human eye. when lit by a light.
    There is therefore a need for a light rail system which overcomes the above-mentioned disadvantages of the prior art.
    The present invention achieves this object by providing a light rail system having the characterizing features of claim 1. Advantageous embodiments of the invention are set forth in the subclaims and the description below.
    The light rail system according to the invention comprises a base rail with electrical power supply lines and a number of attachable to the base rail lights, which are supplied by the power supply lines with electricity. The luminaires comprise lamps with different color temperature or color, wherein the brightness of the luminous means is given by a light at the respective lamp *
    arranged actuating means are controllable. This light rail system can be used in particular as a Schaufensler light rail system for the individual lighting of goods in a shop window or goods display shelf by an exhibition decorator on each lamp by pressing the Betätigungsmiltels the brightness of each Leuchtmittcl set so that the resulting radiated by the lamp mixed light a mixed color temperature or mixed color has, which optimally brings the illuminated object to advantage. For the individual illumination of objects in displays, etc., it is important that the decorator can make these settings directly on the respective lamp, as he can set only during the decorating process, the desired lighting effects and their effect on the viewer can control.
    The light rail system according to the invention is particularly easy to handle if lamps are provided with a first and a second color temperature or color and if the actuating means is designed as a button, with repeated pressing of the button, the brightness of those bulbs having a first color temperature or color increased while reducing the brightness of those bulbs having a second color temperature or color. In this way, the desired mixed color temperature or color can be set faster than with separate adjustments for each luminaire. As an equivalent to a button is also a switch, in particular a tap changer. to view, in such an embodiment, the multiple operation is replaced by the selection of a plurality of switch positions.
    In addition, it may be desirable to change the illumination provided by the lightbar system, for example either as a function of the time of day or as a function of environmental conditions. If e.g. If a display is to be illuminated in full light, all lights of the light rail system should radiate in full brightness. It would be awkward if this had to be done individually for each lamp. For this reason, the invention also provides an embodiment which is characterized by a Lichtsteuereinheil, which is connected by means arranged in the base rail with all of the base rail arranged on the base rail lights, wherein the light control unit controls the brightness of the lamps of all arranged on the base rail lights , The light control unit is expediently integrated into or attached to the base rail. In a development of this embodiment of the invention, it is further provided that the light control unit overrides any brightness settings of the light means individually made by the actuating element, thus ensuring that the control commands of the Light control unit have priority.
    Preferably, however, the existing individual brightness settings are not discarded, but stored either directly in the lights or in the light control unit and set again by a command of the light control unit. By this measure can be quickly and easily switched between a collective control of all lights a light rail and an individual setting of individual lights. It can be pre-stored for each lamp and a factory preset.
    An embodiment of the light rail system according to the invention has proved to be very reliable and has a control line, in which the light control unit communicates with the luminaires by means of pulse amplitude modulation, wherein brightness values for the luminous means of different color temperature or color are coded in the pulse amplitude signal.
    Also high reliability and versatility in the application can be achieved when the light control unit communicates with the luminaires by means of digital signals in which control data for the luminaires of different color temperature or color are coded.
    In order to control many of the inventive light rails from a central, it is further provided that the light control unit has an interface for connection to a higher-level central light control. In this way, for example, all expenses of a business or a business divorce can be controlled centrally. So that the light rail system according to the invention is compatible with the largest possible number of different central lighting controls, while still maintaining its reliable and simple structure, it is further provided that the light control unit converts received from the central light control lamp control commands in Pulsamplitudcnsignale or digital signals in which the lelligkeitswerte are encoded for the lamps of different color temperature or color according to the luminaire control commands.
    In a preferred embodiment of the light rail system according to the invention, which is very reliable electrically, largely self-sufficient and easy to handle, each light comprises electrical contacts, connectable to the control line Lingangsinterface for receiving control signals, a connected to the input interface microcontroller, one with the Microcontroller connected actuating means, light driver circuits, which are controlled by the microcontroller and Lcuchtmittel different color temperature or color, preferably light emitting diodes, which are supplied by the Leuchtmitteltreiberschaltungen with electrical energy.
    With the aid of the embodiments of the invention described so far, it is possible to selectively irradiate individual objects with the respective desired color temperature or color and thereby optimally bring out the object for the viewer. Now, however, a display decoration changes quite frequently, so that the light rail system must be subjected to constant adaptation to the new arrangement of objects to be illuminated. This customization involves adding, removing, and / or replacing lights. In order for this adaptation to take place quickly, simply and yet mechanically stably, the invention provides, in one aspect, a light rail system whose base rail comprises at least one element of a magnetically attractable material extending over the length of the base rail. Furthermore, each luminaire comprises at least one permanent magnet which, when the luminaire is arranged on the base rail, comes into magnetic attraction with the element of magnetically attractable material and thereby holds the luminaire to the base rail. By pulling the lamp away from the base rail with a force that overcomes the magnetic force of attraction, the lamp can be removed again.
    A very high mechanical stability is achieved if two spaced apart, extending over the length of the base rail extending parallel to each other elements of magnetically attractable material are provided, preferably the power supply lines and optionally the control line parallel between the two elements of magnetically attractable Material extend over the length of the base rail, and each luminaire has at least two permanent magnets, which can be brought into magnetic attraction with one of the two elements of magnetically attractable material.
    If the highest mechanical stability of the attachment of the luminaires to the base rail is required, each luminaire can be equipped with a locking element that can be positively or non-positively locked to the base rail. The Verriegclungselement could also be lockable equipped.
    The invention will now be explained in more detail by means of exemplary embodiments with reference to the drawings, in which:

At the front ends of the base rail 2 end pieces 3 are fixed. At the top of a bottom surface 2a of the base rail 2, in the longitudinal direction of the base rail 2, two parallel ones made of an electrically conductive material, such as e.g. Copper, manufactured power supply lines VI, V2. Between the power supply lines VI, V2, a control line S is arranged, which runs in the longitudinal direction of the base rail 2 parallel to the Strotm'ersorgungsleitungen VI, V2. The function of the control line S will be explained below. The power supply lines VI, V2 serve to supply in the profile of the base rail 2 recorded lights LI, L2 with electric power.
    The light LI has three bulbs R, G, B of different colors, e.g. red. green, blue, up. Preferably, the lighting means R, G, B are designed as light-emitting diodes. The lamp LI also has a center of actuation! 10 in the form of a button or switch, with the brightness of the three Leuehtmittel R, G, B are set directly to the light. This occurs when the actuating means 10 is designed as a button. by repeatedly pressing the button, with each button press the I lelligkeit at least one Leuchtmillels R, G, B is changed, so that set different mixed light colors. If the actuating means is designed as a switch, each switch position is associated with a specific brightness of the power means R, G, B, whereby also different mixed light colors are adjustable. In this way, an operator. e.g. a Auslagcndekorateur, each select the optimal for the irradiation of an object color.
    The luminaire L2 has two groups of illuminants WW. CW with different color temperature, e.g. Warm white LEDs and cold-white LEDs, with each group of bulbs allowing three leaks. The light 1.2 also has a • Λ 6
    Actuating means 10 in the form of a button or switch. with which the brightness of the two groups of lamps WW, CW can be set directly at the luminaire. This takes place when the actuating means 10 is designed as a button, by repeatedly pressing the button, each time the button increases the brightness of a Leuchtmittelgruppc and the brightness of the other Leuchtmiltelgruppe is reduced. As a result, different mixed light color temperatures are adjustable. If the charging means is designed as a switch, each sound production is assigned a specific brightness of the illuminant groups WW, CW, as a result of which different mixed-color temperatures can also be set. In this way, an operator, e.g. a Auslagendekoraleur, each select the optimal for the irradiation of an object color temperature of the lamp L2.
    The cross-sectional shape of the lights LI, L2 is formed so that they can be inserted into the profile of the base rail 2 and moved in the longitudinal direction of the base rail 2. In particular, the opposing side walls 2b, 2c of the base rail 2 form a longitudinal guide for the lights LI, L2. In order to secure the lights LI, L2 against falling out of the base rail 2, a magnetic holder is provided. This comprises one or more permanent magnets (not shown) in the lamps LI, L2 and at least one, in this embodiment two, spaced apart from each other over the length of the base rail 2 extending elements 4 of a magnetically attractable material, such. Fisendrähte or iron bars. The elements 4 of magnetically attractable material extend near the side walls 2b, 2c, so that the power supply lines VL V2 and the control line S extend in parallel between the two elements 4 of magnetically attractable material along the length of the base rail 2.

It is understood that a reversal of the elements can be made, i. E. Permanent magnets provided in the base rail 2 and the lights LL L2 are at least partially made of a magnetically attractable material, but this variant is not preferred due to the higher production costs.
    The base rail 2 further has two longitudinal grooves 2e, 2f, which are provided for producing a clamping connection with components of the light rail I designed to be complementary thereto, as shown in FIG. 4 by means of a blanking element 18 C S * * • < l * «

    FIG. 2 shows a perspective view of a middle section of the light rail 1 according to the invention with a luminaire 1. 3 inserted in the base rail 2, wherein the luminaire L 3 is arranged between two blind cover elements 18. Similar to the lamp L2, the lamp L3 also has two groups of lamps WW, CW with different color temperature. e.g. Warm white LEDs and cool white LEDs, each Luchlmillelgruppe includes three Lcuchtmittel, The lamp L3 further has a sunk in a base plate 13 of the lamp L3 arranged actuating means 10 in the form of a button, with the brightness of the two groups of lamps WW. CW can be set directly on the lamp L3, as described above with the lamp L2. The lamp L3 is additionally equipped with a Verriegelungselemcnt 11 which is positively or non-positively verriegclbar with the base rail 2, wherein for changing between a locking position and a release position, a coin 12 inserted into a slot 1 la of the locking element 11 and thus the locking element 11 between the Locking position and the release position is rotated.
    FIG. 3 shows a bottom view of the luminaire 13 shown in FIG. 2. The locking element 11 can also be recognized by four permanent magnets 14a, 14b, 14c, Md inserted in the baseplate 13, which, if the luminaire is used in the base rail 2, also the elements 4 of magnetically attractable material in attraction. Furthermore, a circuit board 16 with electronic circuits in the base plate 13 is screwed. The circuit board 16 has a contact block 15. from which three spring-biased contacts 15a, 15b, 15c protrude, which arrive at the onset of the lamp L3 in the base rail 2 with the power supply lines VI, V2 and the control line S in electrically conductive contact.
    FIG. 5 shows an electrical block diagram of the lightguide system according to the invention with two lights L3, with only one light source WW, CW of each light source group being shown for reasons of clarity. The contacts 15a, 15c of the lamp L3 are connected to the power supply lines VI, V2, whereby the necessary electrical energy for operation of the lamps WW, C'W and the electronic circuits bereitgcstellt. The power supply lines VI, V2 are connected to the outputs Ul, U2 of a power supply unit 27. The contact 15b is connected to the control line S. The electronic circuits comprise an input interface 22, connected to the contact 15b, for receiving control signals, one with the control signal, one with the control signal, one with the * * * * * »» * * * »· ♦ ··· * f · · · · ·« «« «· * «··· • · · · I f · * · * ·«

    Input interface 22 connected microcontroller 21 and light source driver circuits 23, which will be controlled by the microcontroller 21. The luminous flux driver circuits 23 supply the illuminants WW, CW with the electrical energy required to achieve a brightness of the luminous flux predetermined by the microcontroller 21. The microcontroller 21 is also connected to the actuating means 10.
    The light rail system according to the invention also comprises a light control unit 24 having an output 24a which is connected to the control line S. whereby the light control unit 24 can control all existing in a ßasisschiene lights. It is provided that the communication between the light control unit 24 and the lights L3 takes place by means of pulse amplitude modulation, wherein brightness values for the light sources of different color temperature or color are coded in the pulse amplitude signal PA.
    In F'ig. 6 shows an exemplary coding of brightness values by means of pulse amplitude modulation. Accordingly, a pulse amplitude of 24 V means that both groups are switched on at Leuchtmiltcln WW, CW different color temperature. A pulse amplitude of 16 V means that only the first group of lamps CW is turned on. A pulse amplitude of 8 V means that only the second group of lamps WW is switched on, and a pulse amplitude of 0 V means that all lamps are switched off.
    As an alternative embodiment coding of brightness values by means of pulse amplitude modulation is also hintcutet in Fig. 6 that the control data for the lights are transmitted by encoding Digitalignalsc DG of the Lichtstechreinheit 24 to the lights L3, where sic evaluated in the microcontroller and control signals for controlling the Leuchtmiileitreiberschallungen 23 be converted.
    The pulse amplitude signal PA tapped off from the contact 15b of the luminaire L3 is applied by the microcontroller 21 in pulse-width modulation signals PWI PW2 'and supplied to the luminous flux driver circuits 23, wherein in each case a pulse width modulation signal PW1 PW2' for the activation of a group of luminous means WW. CW 'serves. The luminous flux driver circuits 23 apply the lighting means W'W. CW with electrical energy according to the pulse width modulation signals PW1 PW2
    If, on the luminaire L3, the brightness is to be adjusted individually by means of the actuating element 10 of the textbooks W'W, CWr, then set 9 9 ♦ * * * * »* * • * 9 · k · 9 * ♦ ♦ »9
    Control commands from the light control unit 24 override these individual settings. That is to say, the microcontroller 21 always generates from the respective pulse amplitude signals PA the pulse width modulation signals PW1 ", PW2 required for the activation of the illuminant circuits 23. However, the microcontroller 21 preferably stores the individual brightness settings so that they can be readjusted by a command from the light control unit 24 , Alternatively, the light controller 24 may poll and store the individual brightness adjustments.
    The Lichlsteuereinheit 24 has an interface 24b for connection to a higher-level central light control 25, wherein the connection can be made by means of a bus system 26. For example, when the central light controller 25 uses pulse width modulation signals PW1, PW2 as luminaire control commands, the light controller 24 converts pulse width modulation signals PW1, PW2 received from the central light controller 25 into the above-described pulse amplitude signals, for example, as shown in the diagram of FIG standing assignment:
    In the implementation of the pulse amplitude signal PA in Pulswcitenmodulationssignalen PWL, PW2 'for the Leuchtmilteltreiberschaltungen 23, the microcontroller 21, the original pulse width modulation signal PW1, PW2 of the central light controller 25 from.
    It should be noted that the central control unit 25 can also communicate with the Lichlsteuereinheit 24 by means of digitally coded control commands.
