Description

The Invention relates to a lighting device, in particular street or street lighting, with at least one attached to a mast or fastened Lighting unit, which has a light source carrier on which as a light source a plurality of light-emitting diodes are arranged. Moreover, the invention relates a lighting system or a lighting system with multiple lighting devices.

A Such lighting device for the illumination of streets or Because by means of light-emitting diodes is known from practice. The light-emitting diodes are characterized by high light output and efficiency and in particular also high durability, so that there is a need, conventional street and street lighting to replace with LED systems.

Of the Invention is based on the object, a lighting device, especially road or road lighting, of the type described above to create which ensures a perfect illumination of desired lighting areas and also by economic and ecological Efficiency combined with a simple and functional design distinguished. According to a first aspect of the invention, such a lighting device be specified while According to a second aspect of the invention, a lighting composite be created with a variety of lighting devices which is an economic one and ecological efficient lighting of roads and ways guaranteed.

to solution this object teaches the invention in a generic lighting device the type described that the light source carrier designed as a light module carrier is attached to the several light modules that in one or a plurality of light emitting diodes each arranged a plurality of light emitting diodes are and that the individual lighting modules mounted independently of each other on the illuminant carrier are. - The Invention is therefore characterized by a simple modular design in which a plurality of individual light emitting diodes each in a light module are combined and several light modules for Use come. Such modules can be easily manufacture and pre-assemble. Particularly advantageous are the Position lighting modules variably on the light module carrier, eg. In attach different mounting positions on the light module carrier. In the course of the production can then be universally applicable standard modules produce, which on differently structured light module carriers for Use, so with identical or similar modules, but different designed illuminant carriers can be worked. This is particularly useful because by design and in particular form of the light module carrier the emission characteristic the lighting device can be influenced. So is in the Frame of the invention preferably worked with an arcuate or U-shaped light module carrier, thus formed in cross-section arcuate or U-shaped or trough-shaped is. The individual lighting modules are positioned along the arch or positionable, so that by the arch shape on the arch arranged light modules radiate in different directions. It can for different Lighting devices Light module carrier with different arch shape are used, which then have a different emission characteristics even when working with identical or similar lighting modules.

It is within the scope of the invention that one or more of the lighting modules are slidably disposed on the light module carrier. If, for example, an arcuate luminous module carrier is used, the emission direction of the luminous module can be varied by displacement or positioning of the luminous modules on the luminous module carrier, so that adaptation to geographical conditions, different distances between luminaires, mast heights, etc. can take place. The term "arcuate" means z. B. "sections" arcuate or other bow shapes, the "arc" is aligned in the direction or along the path to be illuminated. However, also light module carrier are included, in which the arch shape is approximated by a polygonal shape, so that a polygonal illuminant carrier is realized, which has a plurality of straight contact surfaces for the lighting modules. Such as arcuate, but polygonal constructed light module carrier can a variety of contact surfaces, for. B. three to fifteen, preferably five to ten, z. B. have six to ten contact surfaces for mounting according to many lighting modules. The surfaces are arranged at predetermined angles to each other, so that the desired radiation characteristic is selected by appropriate design of the light module carrier and thus optimal illumination z. B. succeeds a long and narrow area. In such a polygonal constructed carrier, it may be expedient if the individual lighting modules are not arranged displaceably on the carrier, since a displacement along the straight surface would only slightly change the emission characteristic. Particularly useful is a displaceable arrangement when working with a "non-cornered" arcuate support in which the Shifting a module along the arc at the same time changes the beam angle.

The individual lighting modules preferably have a module housing, in which one or more LEDs and optionally the LEDs associated with lenses and preferably an electronic control system for the Light-emitting diodes are integrated. So it is within the scope of the invention that in a module housing a lighting module one to six, z. B. two to four, preferably three light-emitting diodes are arranged. The multiple LEDs can side by side in the case be arranged, wherein the housing preferably such on the carrier is attached, that the plurality of light emitting diodes transverse to the arcuate carrier. While Consequently, by appropriate positioning of the light module the carrier the illumination along the road or path longitudinal direction is influenced by selecting or setting the LEDs in a luminous mode, essentially the width illumination a path or a road affected. For this purpose, it may be advantageous if the light-emitting diodes within a module housing Aligned or aligned in different directions are. Particularly preferred are one or more light-emitting diodes within a lighting module attached with adjustable beam angle, z. B. arranged on rotatable shafts. It may also be advantageous, a or several fixed LEDs and both sides of this to provide fixed LEDs arranged light-emitting diodes. This makes it possible to create universally applicable lighting modules which in the course of installation to the desired conditions can be adjusted. Within a light module can also different light emitting diodes with different emission characteristics and / or different lenses are used. The module housing is preferably made of metal, for. B. aluminum, manufactured. This can be a optimal heat dissipation to reach. The front side of the module housing is preferably with a transparent cover made of z. B. transparent plastic, wherein in the transparent cover lens or lens systems can be integrated. At the LED's associated lenses, which z. B. be integrated in the cover plates can, are preferably Fresnel lenses, faceted lenses, strip lenses and / or hexagonal lenses.

Basically exists the possibility, the arcuate or polygonal light module carrier one piece or massively manufactured. In an advantageous embodiment of the invention However, it is proposed that the arcuate or polygonal light module carrier several plate-shaped or shaped slices support segments is composed, with individual carrier segments with different Forms are used, which in the course of the composition of the Light module carrier in the desired Create shape. In this respect, modular work can also be used here. The individual carrier segments are z. B. made of metal. It is therefore preferable to segment plates in the form of ring segments, z. B. semicircle segments or pitch segments stacked on top of each other. Because of Cost and weight savings, it may be appropriate between the individual support segments made of metal filling segments from z. B. to arrange plastic. In particular, the carrier segments Metal are preferably cut from metal sheets, e.g. B. in the way of laser cutting. The filling segments made of plastic can z. B. be cut from plastic sheets, z. B. also in the way of Laser cutting or by means of water jet cutting. The However, the invention also includes embodiments in which the support plates and / or filling segments are formed as stampings. In the course of assembly are preferably the carrier segments and optionally filling segments by means of clamping devices, for. B. threaded rods or threaded screws braced to the light source carrier.

The use of different carrier segments with different shapes allows the design of a functionally correct form of the illuminant carrier without consuming material processing of a z. B. massive illuminant carrier would be required. Thus, it may be expedient to work with four different plate-shaped support segments, which in particular have different widths and optionally prepared recesses for the assembly of further components. It is particularly advantageous if the carrier segments and possibly filling segments are made of different shapes in such a way that the illuminant carrier has a cable receiving channel open at the front. This is achieved in that in the region of the cable receiving channel narrow carrier segments with a small width and above and below the cable receiving channel carrier segments are used with a larger width, so that at least two types of segments is used. Furthermore, a third type of segment can be used, which has prepared recesses for the attachment of the modules. Finally, a fourth segment type can be used which forms the upper and lower terminus of the illuminant carrier. Details are shown in the figures. The wiring of the modules is always facilitated if a corresponding cable receiving channel is provided. Due to the front-side arrangement, it is not necessary to thread the cables coming from the modules through corresponding openings. Rather, these can easily in the front Kabelaufnahmeka be inserted. In this context, it is useful if in the region of the cable receiving channel (movable or adjustable) cable holder, z. B. retaining plates, brackets or the like are arranged, which are brought after inserting the cable in the desired position or folded and close the cable channel only at some breakpoints. The described structure of metal support plates and plastic filling segments can be exploited by the way for the "wiring". Thus, the metal segments can be used as conductors and the plastic segments as insulation between the conductors. This is particularly important in connection with the lighting network, which will be described in detail.

It is within the scope of the invention that the lighting unit adjustable attached to the mast. This should not mean height adjustment. Alternative or supplementary the lighting unit is preferably pivotable on the mast attached, and usually in two mutually orthogonal pivot directions. Therefore it is useful if the lighting unit gimbal by means of a universal joint is hinged to the mast.

The Illumination of streets on the other hand, or ways on the other hand is often used with lighting devices realized, which have only a single lighting unit. However, it may also be appropriate a lighting device with a plurality of lighting units equip, at different heights arranged (on a mast) and / or different angular orientation are. In addition, you can different lighting units are used. This may be appropriate, for example, then if an area of a street with peripheral sidewalks or the like with different Illuminating characteristics should be illuminated. The lighting in the area of the street can with greater intensity than in Be provided area of the sidewalk. In addition, different lighting colors for different Lighting areas are realized.

To Another proposal of the invention, it is advantageous if the intensity individual lighting modules and / or individual light-emitting diodes within a lighting module is adjustable. This can basically have a within the lighting device, e.g. B. within the mast and / or within the illuminant carrier and / or within the light module arranged control or regulating device success. However, it can also provide an external control be. For this purpose, further details will be explained below.

The Light-emitting diodes are preferably designed as white light LEDs. However, the invention also includes embodiments with other colored LEDs. in principle is also the use of such light emitting diodes conceivable, the color adjustable is.

In advantageous training suggests the invention provides that the illumination carrier has an illuminated information surface, which outside the actual lighting areas is arranged. It can it is a transparent or semi-transparent light guide plate act, in which the light over frontally arranged light sources, eg. B. frontally arranged Light emitting diodes is coupled. Such information surfaces can, for example as advertising space or the like can be used. The coupled light can over a mechanical structuring or laser structuring of the light guide plate or by a trimmed on or between part surfaces Film or transparent printed film to be decoupled, so that the information displayed, z. B. illustrated logos or such advertising information, light up. By several in a row arranged Lichtleitplatten each with its own LEDs for Light coupling can changed Pictures / logos / texts are displayed. The light guide plates can through one or two transparent plastic plates, z. B. polycarbonate plates, Makrolonplatten or other transparent materials or coatings become. The light emitting diodes for light coupling into the light guide plate are preferably designed as RGB LEDs. The use of light emitting diodes comes because of the advantages described special significance. The However, the invention also includes embodiments in which in addition to a lighting device "conventional" lamps provided are, for. B. incandescent lamps, Gas discharge lamps (eg, sodium vapor lamps) or the like. By suitable Combinations of LEDs with one or more (possibly different) conventional lamps high luminous efficiency can be an optimization in terms of uniformity the illuminance along the road and / or with respect to the light spectrum with high effective total light output respectively.

The invention with particular importance is also a lighting network, which has a plurality of lighting devices, each with a plurality of light-emitting diodes, a plurality of sensors, at least one power supply network and at least one communication and / or control bus. In this respect, it is a lighting system or a lighting system for the illumination of streets, paths or the like lighting areas, the individual lighting devices preferably to a low voltage network with a supply voltage of 10 volts to 50 volts, z. B. 12 volts, 24 volts or 48 volts are connected. Consequently, the composite according to the invention is characterized by a low-voltage network, which is preferably "relocated" in practice. However, the invention basically also includes a lighting network with a conventional supply voltage of 230 volts. The safety extra-low voltage of z. B. 24 volts, which is already widely used in industrial automation systems, but in addition to the increased safety has the advantage of extending the maintenance intervals. In addition, the installation and maintenance costs can be reduced, since lower requirements can be made of the training level of the maintenance specialists or maintenance personnel. In the case of a 230 volt voltage network, it is possible to assign each individual lamp its own power supply, which is integrated, for example, in the mast, so that then can be used with conventional network with low-voltage lighting carriers. More preferably, however, a plurality of lighting devices are connected via a low-voltage network to a common low-voltage power supply, which may be arranged in a low-voltage distribution or in a lamppost.

In the lighting system according to the invention, it is further provided that the individual lighting devices are interconnected via at least one communication bus or device bus, via which individual lighting devices, individual lighting modules of a lighting device and / or individual light emitting diodes of a lighting module can be controlled. The individual lighting modules are therefore connected to each other via a bus system. This allows the light intensity of individual light modules, light-emitting diodes or groups of light-emitting diodes to be set via the bus. For this purpose, one or more sensors are preferably provided which z. B. on the mast, the lighting support or in the mast are arranged. Alternatively or additionally, however, an external control device, for. B. be provided at the operator of the network. The control can also be automated. For this purpose, timings may be appropriate, which make only a switching on and off of the individual modules or LEDs. This can be done via the existing ripple control signal. Alternatively, switching on and off can be carried out via an Internet access, via a communication access or also via the radio time signal DCF77 of the Physikalisch Technische Bundesanstalt. For this purpose, a suitable switching module can be realized. However, the effectiveness is further increased by incorporating "external influences" into the control in the course of an automated control. For this purpose, it is advantageous if one or more sensors are provided, which z. B. in the range of one or more lighting devices may be arranged, for. B. in the range of the mast and / or in the field of lighting unit. For example, these may be motion sensors, brightness sensors, cameras or the like. In this connection, it is also possible to assign a motion sensor to each luminaire or a plurality of luminaires (for example, every second or third luminaire), so that a very specific illumination can be effected, in particular, as needed. This aspect is of particular importance in the context of the invention. Because with the help of this electronic control optimal light distribution adapted to the road and its respective usage situation can be achieved, at the same time increasing the economic and ecological efficiency. The communication between the individual components takes place via the bus, to which the lights and the sensors are connected. In this context, it is particularly expedient if the individual lighting devices of a lighting network are operated in different modes of operation, which are controlled as needed. So it is possible to operate the lighting devices of the network or at least some lighting devices (temporarily) in at least a first mode of operation, for. B. with reduced light intensity. The lighting devices are thus, if no sensor signals are given "dimmed down", z. B. on empty roads or sidewalks. Depending on the sensor signals, the lighting devices or some lighting devices can then in at least a second mode of operation with z. B. increased light intensity can be operated. This means that then in the presence of people, the lighting devices or individual lighting devices are locally "dimmed" high, to a "standard" lighting. At the same time there is a recognition of a person and / or a vehicle, so that if necessary there is the possibility to illuminate sidewalks and streets separately or specifically, depending on the needs situation. In conjunction with the sensors, the light can thus be controlled in such a way that, depending on traffic situations, pedestrians and also cyclists are particularly well recognized by motorists. The current location, where pedestrians and cyclists are in particular, is particularly illuminated. If there are no pedestrians or moving vehicles on the street, the modules are dimmed. In the direction of movement behind the passers, the light z. B. dimmed, in front of them the light z. B. started up. The lights can also be equipped with light emitting diodes of different colors, so that z. B. walkway or bike path with egg be illuminated in a different light than the road itself.

Especially if with low DC voltages of z. B. 24 volts or 48 volts is working, the supply lines can be connected to the communication bus to a common multi-core cable, z. B. a four-wire Combine cable. In the course of laying work can then easily realized both the power supply and the communication become. However, the invention also includes embodiments in which a communication about Cable completely is dispensed with and instead is communicated wirelessly. This is especially useful if you have existing supply networks resorted shall be.

Of the Wiring effort leaves Minimize if all Lights or modules are connected in parallel. You get, therefore all the chosen ones DC. In the modules, the currents are single or in series switched LEDs regulated. In each lighting unit, an internal control or control electronics to be arranged, via which the light-emitting diodes operated, the control or electronic control z. B. over the Bus system can be controlled by an external control device.

Of the described communication and / or control bus can z. B. - as already explained - wired be formed and combined, for example, with the supply network become. However, it may also be appropriate to be on a wired Bus to dispense and use a wireless bus. As part of The invention also provides the possibility to work with several bus systems, eg. B. a wired Bus for the control of the lights and a wireless provided beyond Bus, which take on additional functions can be described below.

So can over the bus or over An additional Bus for another proposal the collection of consumption data neighboring housing units and the accounting of neighboring households Residential units of converted electrical energy, of water consumption, of gas consumption. It can Status or alarm messages and / or information transmitted become. This bus system is preferably wireless. It then there is the possibility the z. B. arranged in neighboring households sensors in the bus system to integrate. It can also be created a wireless bus system, with at least one Bus subscriber in the luminaire, which transmits information from and to neighboring residential units, offices or small businesses. The wireless bus system is also used for accounting of matter, Energy and / or information of neighboring residents or the housing units used energy, matter and information. The wireless bus system can also be used to control actuators become. about the wireless communication device becomes an energy management system realizes, with the housing units, buildings and energy systems more economical, ecological and ultimately be used more efficiently, with selected energy consumers dependent on the energy saving offer z. B. temporarily off or can be operated with less energy. So z. B. Freezers with the Energy providers communicate and with low energy supply their switch-on times vary.

In the individual lights or some lights can each z. B. Wi-Fi access point and / or wireless internet access be integrated. Residents can talk about this Communicate WLAN with the Internet or with other communication sets. About these Wireless communication of smart LED lights can be the "last mile" of communications providers replace.

The Consumption or the sensor data are on a web-based, decentralized Monitoring system preferably via transfer the internet and in Internet sites registered after an authentication of each authorized user with an internet browser can be and thus always an overview of the consumption and the costs can be created. That way you can save energy after the actual monthly consumption can be calculated. Additional alarm messages (hospital, Police ...) with parameterizable priorities generated and processed become. In addition, fully automated, Emails or SMS will be sent in case of special events. The individual sensors, gas meters, Electricity meters, Heating counters, water meter etc. can with simple serial interfaces, eg. B. according to the RS232 standard be equipped. In this case, the RS232 signal is switched on uniform sensor interface implemented in a radio signal and on switched the wireless sensor bus. Via RS232 / WLAN adapters the Sensor signals also directly over transfer the internet to a server become.

Overall, the luminaire according to the invention and in particular the communication network according to the invention can additionally be used as it were "in a different way" in order to achieve the described functionality. The connection between the individual luminaires will consequently be used for other communication exploited, so that the laying of other communication lines, eg. As telecommunications lines, unnecessary.

in the The invention will now be described by way of example only illustrative drawings closer explained.

In the 1 to 6 is a lighting device 1 shown, which is used as street or street lighting. It consists in its basic structure of a mast 2 and a lighting unit attached to the mast 3 , this lighting unit 3 a light source carrier 4 has, as the lighting means a plurality of light-emitting diodes 5 are arranged. 1 shows that on the illuminant carrier 4 several lighting modules 6 namely nine lighting modules 6 are attached, wherein in each of these lighting modules 6 one or more LEDs each 5 are arranged. The LED lamp according to the invention is thus characterized by a modular design, because the individual lighting modules 6 are independent of each other on the illuminant carrier 4 mountable. The light modules 6 can be prepared in the course of manufacture as prefabricated modules and then to illuminant carriers 4 Different design can be mounted in a variety of numbers. Because the individual lighting modules 6 be in different mounting positions on the light module carrier 4 attached. There is always the possibility that the individual lighting modules 6 slidable on the light module carrier 4 are arranged. In the embodiment, this is not provided, but rather the individual lighting modules 6 fixed in fixed predetermined mounting positions, the individual mounting positions can be optionally equipped.

The light module carrier 4 is (in cross-section) arcuate, z. B. circular arc-shaped, ie the light module carrier 4 has in cross-section substantially the shape of a circular arc section, z. B. a semicircle or a pitch circle. The individual lighting modules 6 are positioned along this arc across it. In this case, the figures make clear that circular arc shape in the present case does not mean an exact circular arc shape, but rather a polygonal shape, ie the "circular arc" is composed of a plurality of straight sections, these straight sections the contact surfaces 7 for the lighting modules 6 form. The straight sections of the "circular arc" are thus arranged at a certain angle to each other. In this way it is achieved that the individual lighting modules 6 relative to the surface to be illuminated, z. B. the road or the path are arranged at different angles, so that the desired illumination characteristic is achieved. Thus, with the aid of the luminaire according to the invention, a strip-shaped illumination area is uniformly illuminated, the length of this illuminating strip being a multiple of its width. Overall, roads, paths or the like can be excellently uniform and at the same time exclude surrounding areas. The arched carrier 4 runs with its longitudinal direction T along the path to be illuminated. The modules are oriented with their longitudinal direction L transverse to this longitudinal direction T and thus transversely to the path.

Furthermore, the figures show that the individual lighting modules are each designed to be identical and for the use of one to three LEDs with possibly upstream lenses 8th are set up. By appropriate occupation of the three positions P1, P2, P3 (or "not" occupation) and by appropriate selection of the radiation characteristics of the light-emitting diodes 5 and the upstream optics 8th the desired radiation characteristic can be manipulated in a variety of ways. These variations are further enhanced by the fact that the two outer LEDs in the positions P1, P3 within a module 6 are adjustable. For this sit the light-emitting diodes 5 the two outer shots P1, P3 on waves 9 so that it turns by turning the waves 9 the angle can be adjusted. A lock is provided by screws on the side of the housing.

Because every light module 6 has a module housing 10 on, with the individual light-emitting diodes 5 within the module housing 10 are arranged in the appropriate manner. The module housing 10 consists in the embodiment of aluminum, so that an excellent heat dissipation takes place. especially the 5a to d show that the case back a receptacle 11 for an unillustrated control electronics on z. B. has a control board to which the individual LEDs are connected. The middle LED 5 , P2 is stuck at the bottom of the module housing 10 assembled. The two outer LEDs 5 , P1, P3 sit on the already described waves 9 , which are laterally in the module housing 10 are inserted and can be turned. They can be locked on the side of the housing with two screws.

For the front side has the LED housing 10 a recording, z. B. cutout as a recording 12 for the light-emitting diodes or the LED boards (each LED is usually mounted on an LED board). The individual images P1, P2, P3 are with lenses 8th covered. The front recess 12 , in which the receptacles P1, P2, P3 are arranged, after use of the LEDs or LED boards and the lenses 8th with a transparent cover 13 from z. As polycarbonate covered. The lenses 8th can also in the cover discs 13 be integrated, or be formed by this. On the back is the already described chamber 11 incorporated for mounting the control board (see. 5c ).

The described prefabricated modules 6 can then be on the light source carrier 4 Fasten. Construction and installation of the illuminant carrier 4 be based on the 2 . 3 and 4 explained.

First of all, it can be seen that the arcuate or polygonal illuminant carrier 4 from a variety of carrier segments 14a . 14b . 14c . 14d is composed, wherein in each case a plurality of carrier segments are used with different shapes. The. 2a to 2d show that the illuminant carrier of four differently shaped carrier segments 14a -D is constructed, which are each made of metal. In addition, between the carrier segments 14a -D filling segments 15 used in plastic. This minimizes manufacturing costs and weight. The carrier segments of metal are cut by means of laser cutting of sheets to the illustrated ring segments. A comparative examination of the figures shows that the individual carrier segments 14a -D and the filling segments 15 then be clamped by means of clamping means to the lamp carrier, wherein the clamping means 16 be formed in the embodiment of threaded rods (with nuts). The illuminant carrier or module carrier 4 thus consists of stacked ring segments 14a -d, 15 with different outer contours but identical bore coordinates. The segments 14a -d, 15 be with the threaded rods 16 aligned with each other and tightened by nuts. So then creates a solid ring segment as a light source 4 on whose outer periphery surfaces for receiving the lighting modules are arranged. The surfaces 7 are arranged at certain angles to each other, so that an optimal illumination during operation arises. The bearing ring segments 14a -D are made of stainless V2A sheet and to reduce weight, the filling segments described 15 from z. B. interposed transparent polycarbonate. Due to the different shape of the segments results in the course of stacking, for example, in 4 recognizable contour of the illuminant carrier 4 , This in 2a described sheet metal 14a forms the lower and upper end of the wearer. This is followed by segments 14b , c according to 2 B and 2c at. In the central area are segments 14d according to 2d used, which have a smaller width, so that in 3 and 4 recognizable cable receiving space 17 arises. In the area of this cable receiving space 17 are also cable holding plates 18 or cable retaining flaps arranged, which can be opened and closed after the modules are mounted. Because of in the segment 14d according to 2d provided pocket-like recesses 19 become in the course of stacking receiving pockets 20 for fasteners, z. B. nuts, to which the modules 6 can then be fixed (cf. 3 ). These cut T-shaped bags 20 or grooves are in 3 recognizable. 4 then shows the strained carrier without mounted modules with the individual mounting surfaces 7 for the modules.

1 shows, moreover, that the lighting unit 3 adjustable on the mast 2 is attached. A height adjustment is not provided in this case. The lighting unit 3 is however via a universal joint 21 gimbal-mounted to the mast so that the lighting unit can rotate about the axes a and b.

6 shows a modified embodiment of the invention, in which on a mast two lighting units 3 are fixed so that a roadway on the one hand and a footpath on the other hand can be illuminated separately by appropriate orientation or design. The lighting can also be done with different colors of light. For example, the street lighting can be white, but the sidewalk lighting can be yellow or the like. These are the two lights 3 mounted at different heights. The roadway lighting comes with a Lamp reaches about six meters in height, while the footpath lighting is hung at least one meter lower. In this case, a plurality of lighting devices are usually placed at a distance of 30 meters.

Incidentally, in 1 recognizable that the illuminant carrier 3 on the upper side and optionally on the underside with a cover plate 22 can be closed. In the embodiment, at least the upper cover plate 22 designed as a light guide plate, which has an information surface, for. B. can form advertising space. This can be in the light guide plate 22 with the help of light emitting diodes, not shown, couple light. Consequently, the luminaire can simultaneously serve as an advertising space or information surface.

It is convenient to operate the lights with a 24 V DC. In this case, usually a variety of lights are placed along a path or a road. A variety of such lights 1 can be combined to form a lighting group B. Such a lighting system is in 7 indicated schematically. The individual luminaires are connected to a common low-voltage network 23 with an operating voltage of z. B. 24 volts connected, in parallel. This facilitates the wiring. In addition, the individual lighting devices are via a communication and / or control bus 24 interconnected, over which individual lighting devices 1 , single light modules 6 and / or individual light-emitting diodes 5 a light module 6 are controllable. The supply lines 23a . 23b and the bus lines 24a . 24 can be combined to form a common four-wire cable. In the exemplary embodiment, each control module has control electronics 25 integrated, via which the modules to the supply network 23 and / or the bus 24 are connected. About the bus 24 can z. As the light levels of individual LED modules, individual light-emitting diodes or groups of light emitting diodes can be set or controlled. It is intended, sensors 27 to arrange at some (or even at all) lighting devices, preferably motion sensors, cameras and / or brightness sensors or used as motion sensors cameras with high sensitivity in the infrared range. Such a combination of sensors 27 on the one hand and controllable light-emitting diodes 5 On the other hand allows the demand-dependent control of the individual lights 1 or modules 6 , Thus, in particular, there is the possibility that the light intensity is initially operated in a first mode of operation with low light intensity. That means the lamps are dimmed down. If necessary, if z. B. a vehicle or a pedestrian approaches, individual lights or all lights can be operated in a standard manner in a second mode of operation, ie the light intensity is dimmed as high. This needs-based or demand-oriented control represents a first essential aspect of the lighting system according to the invention.

This can be done, for example, with the illustrated wired bus 24 to which on the one hand the lights 1 and on the other hand the sensors 27 connected, realize. The system controls itself, so to speak, so that no external control must be provided.

In an advantageous embodiment of the invention, however, it is also possible to control the system from the outside or at least to configure. This can be useful if it is to the bus 24 and / or one or more lights 1 Internet access, eg. An internet gateway 28 with Wi-Fi access point 29 connected. Via this internet access, the lights can be over the internet 30 communicate with the operators and z. B. request maintenance or by the operators unscheduled on and off. In addition, a configuration of the system can be made via the Internet access.

Another aspect of the invention is the possibility that light system B or its bus 24 for a more extensive "alien" communication, that is for a communication in connection with data and information, which in principle have nothing to do with the operation of the lights.
