Description

The invention relates to a lighting system as known from larger parking garages, e.g. in airports or the like, which comprises light elements, sensors and signal lights. The invention further relates to a parking guidance system having the illumination system.Signal lamps for indicating the occupancy state of a parking lot for parking guidance systems are known from the prior art. These are based on the principle that a sensor is used to determine whether or not a parking space is occupied by a vehicle. As a function of this, the signal lamp is activated, which then indicates the occupancy state of the parking lot. Normally, in the case of a parking lot occupied, a red light is emitted, while, on the other hand, a free parking lot is indicated by a green light.Furthermore, it is also necessary to illuminate the parking garage, especially the parking lot or lots and the adjacent runway, wherein elongated illumination systems, for example in the form of light bands, are generally used here.It has now been shown that the three above-mentioned components, namely the sensor, the signal lamp and the lamp for general lighting, are arranged in the most varied ways in the prior art.It is thus known, for example, to arrange the signal light outside the parking space in the edge region of the travel lane, since the signal light is particularly well visible here and, accordingly, in the case of searching for a free parking space, it can be quickly detected whether or not a parking space is available in a specific region. In this case, on the other hand, the sensor is often arranged separately from the signal lamp centrally above the parking facility in order to be able to reliably detect its occupancy. Again separately from this, the general lights of the light band are arranged, with the aid of which on the one hand the parking space and on the other hand the travel lane are to be illuminated. In this first version, therefore, all three components are arranged next to one another in different planes, which on the one hand means a high outlay on assembly and on the other hand is unattractive (cf. FIG. 1, left-hand arrangement example).It is therefore also known from the prior art to combine the sensor and the signal lamp to form a unit, wherein in this case the sensor signal lamp unit is then generally arranged centrally above the parking space. Laterally separated from this, in the edge region of the travel lane, the lights are then arranged for general lighting. Here too, there is therefore an at least partial separation of the components (cf. FIG. 1, central arrangement example). In addition, the sensor signal light unit is provided spaced apart from the travel lane and is therefore difficult to see under certain circumstances.Finally, the prior art also discloses a sensor signal light unit which is designed such that it does not have to be arranged centrally above the parking space, but can be arranged laterally thereof, again in the edge region of the runway. By virtue of a special configuration of the sensor, the latter is nevertheless able to evaluate the parking space now lying obliquely below with respect to its state of occupancy. At the same time, the signal lamp is easily visible. However, in this case as well, there is a separation between lamps for the general lighting and the sensor signal lamp unit (see FIG. 1, right arrangement example).KR 10 2012 006 383 A discloses a lamp and a lighting system for a parking facility. WO 2012 / 158 036 A1 discloses a lamp device having a first element which can be mounted on a parking garage. CN 201 903 935 U discloses a parking space display panel. KR 10 2009 125 350 A discloses a lamp device having a parking space display device. DE 10 2011 082 844 A1 discloses a lighting arrangement, in particular for emergency route lighting.Proceeding from the known prior art, it is now an object of the present invention to provide a space-saving, elegant and easily mountable lighting arrangement for parking guidance systems.This object is achieved by the subject matter of the independent claims. The dependent claims further develop the central idea of the invention in a particularly advantageous manner.To achieve this object, according to the invention, a lighting system is provided which has a lighting element with first lighting means, a sensor for detecting the occupancy state of a parking space and a signal light with second lighting means for displaying the occupancy state of the parking space detected by means of the sensor. The lighting system further comprises a carrier element, wherein the light element, sensor and signal light are all arranged on this carrier element. The lighting system further comprises a cover, wherein the sensor and the signal lamp are formed integrally with the cover and are mechanically coupled via these to the carrier element.In the context of the invention, a carrier element is understood to mean any one-part or multi-part structure to which the three components, light element, sensor and signal lamp, can be provided / fastened jointly, which also comprises, for example, a carrier system of known light band systems. Of course, any number of the components light element, sensor and signal light or also further components can also be provided on a corresponding carrier system.The arrangement according to the invention of the luminous element, sensor and signal lamp combined on a carrier element provides a very space-saving, compact and elegant construction and arrangement of the lighting system with simplified assembly outlay compared to the prior art.The illumination system is preferably of elongate design and has in particular an elongate carrier element. In a preferred embodiment, the luminous element on the one hand and the sensor and the signal lamp on the other hand are arranged along a longitudinal axis of the preferably elongate illumination system.Thus, by arranging along the longitudinal axis of the elongate illumination system, a very orderly and elegant appearance can be achievedAdvantageously, the light element, sensor and / or signal light are mechanically coupled to the carrier element; for example, by means of screws, welding, clamping connections, etc.By means of the mechanical coupling just mentioned, a very advantageous and simple assembly of the illumination system can be achieved.Most preferably, the luminous element is directly mechanically coupled to the carrier element.As a result of the direct mechanical coupling, even further components can thus be saved, which in turn saves space and, due to the smaller number of assembly steps, also reduces the assembly effort.Likewise, the luminous element can be mechanically coupled indirectly to the carrier element.By means of an indirect mechanical coupling, it can be achieved that existing carrier elements can be used which were previously not suitable for a particularly direct mechanical coupling of the lighting element, sensor and signal lamp, but can be used by means of an indirect mechanical coupling for the lighting system according to the invention.The illumination system preferably has a plurality of luminous elements and / or a plurality of sensors and / or a plurality of signal lamps.Advantageously, on the one hand, sensors and signal lamps are arranged on the carrier element alternately to the lighting elements on the other hand.The alternating arrangement can thus provide a lighting system which makes the appearance of the lighting system even more elegant and more orderly and additionally reduces the assembly outlay even further, since the elements are already in an arrangement advantageous for a parking guidance system, for example. A plurality of lighting systems can thus be arranged in a row in a type of modular construction to form a parking guidance system according to the invention.In a further advantageous embodiment of the lighting system, the sensor and the signal lamp can form a preferably moisture-proof unit.The advantageous unit of sensor and signal light can achieve that already present units of sensor and signal light can be used for the lighting system. Likewise, a modular construction of the lighting system can be achieved as a result, which further reduces both production costs and assembly effort.The lighting system preferably further comprises an electrical line arrangement for electrically coupling the sensor and the signal lamp on the one hand and / or the lighting element on the other hand. Particularly preferably, the electrical line arrangement has a first electrical line arrangement for electrically coupling the sensor and the signal lamp and a second electrical line arrangement for electrically coupling the luminous element. Most preferably, the one (single) electrical line arrangement serves both for the electrical coupling of the sensor and the signal lamp on the one hand and for the electrical coupling of the luminous element on the other hand.It is very advantageous in the case of the electrical line arrangements just mentioned that, in the case of a first electrical line arrangement for electrically coupling the sensor and the signal lamp and a second electrical line arrangement for electrically coupling the luminous element, the sensor and the signal lamp on the one hand and the luminous element on the other hand can be operated separately and thus independently of one another with power. If the lighting system furthermore advantageously has a (single) electrical line arrangement for electrically coupling the sensor, signal light and lighting element, space can be saved and the cabling outlay can be reduced. In this case, the lines of the lighting system can preferably be used simultaneously for the sensor and the signal lamp. For example, the first electrical line arrangement can also be used by all components and the second electrical line arrangement can be used by at least some of the components, wherein the latter can be coupled to an emergency power network, for example.Furthermore, the lighting system can have an additional element for receiving the first electrical line arrangement for electrically coupling the sensor and the signal lamp. In this case, for example, a spatial separation between the first and second electrical line arrangements can be present. The additional element can be provided, for example, subsequently as a receptacle for the second electrical line arrangement on the carrier element.The additional element achieves the advantage that a lighting system is provided which can already protect the electrical lines, in particular for the sensor and signal lamp, from external environmental influences, for example, by the additional element. It is also possible to retrofit already existing light elements (for example. This is also possible to provide light band systems) with second electrical power arrangements.For controlling the sensor and the signal light on the one hand and / or the lighting means on the other hand, the lighting system according to a further embodiment can have a control element. This can be, for example, a central control unit, which is preferably a central control unit of the light elements.Thus, the control by the control element allows the sensor, signal light and lighting means to be controlled as desired and optionally connected to one another in terms of control technology, in order, for example, to adapt the lighting system to different requirements and / or to fulfil certain functions, for example for parking control systems.This achieves the particular advantage that the lighting system can be safely used even under difficult environmental conditions, such as in parking garages.The lighting means preferably have asymmetrical light inserts. Particularly preferably, the lighting means further comprise separately controllable light regions.Due to the preferred asymmetric light inserts and the particularly preferred separately controllable light regions, the light can be efficiently adapted to the application, e.g. in a parking garage, in that e.g. certain regions are illuminated more and certain regions less.The lighting means of the lighting system can be LEDs and / or an LED module.The invention further relates to a parking guidance system which has a multiplicity of the lighting systems according to the invention. If these are of elongate design, they can be used in the form of a light band system. At least one lighting system can be assigned to at least one parking space. In particular, at least one sensor and signal lights combination (unit) of the lighting system should be able to be assigned to a parking facility.Some exemplary embodiments of the invention are explained in more detail below with reference to the attached drawings. Like reference numerals are used for the same features.

The lighting system 10 has a light element 1, a sensor 2 for detecting the occupancy state of a parking lot, and a signal light 3 for displaying the occupancy state of the parking lot detected by means of the sensor 2. Light element 1, sensor 2 and signal light 3 are arranged in a combined manner on a carrier element 4. Advantageously, the lighting element 1, the sensor 2 and the signal lamp 3 are arranged on the carrier 4 in such a way that a connection that is tight with respect to the environment, preferably moisture-tight, particularly preferably according to protection class IP65, is achieved between them. In the context of the present invention, "sealed against the environmental conditions" is advantageously understood to mean that it is likewise effectively sealed against contaminants and / or moisture and / or dust and / or other particles.Preferably, the illumination system 10 is designed to be elongate. Light element 1, sensor 2 and signal light 3 can be arranged along a longitudinal axis, preferably in a line of the elongate illumination system 10. The carrier element 4 is then preferably likewise of elongate design and preferably extends along the longitudinal axis of the illumination system 10. It can be straight or curved. The longitudinal axis can also lie in a curved surface or in a surface with another geometry, so that the illumination system 10 can be adapted to different requirements, for example of a parking system. Advantageously, on the one hand, sensor 2 and signal light 3 are arranged on the longitudinal member 4 alternately with the light element 1, i.e. light element 1, sensor 2 and signal light 3 alternate, for example, as seen along a longitudinal axis. Depending on requirements, the lighting system 10 can also provide a partially or non-alternating arrangement of the lighting element 1, the sensor 2 and the signal light 3.The arrangement of the luminous element 1, the sensor 2 and the signal lamp 3 on the carrier element 4 is preferably effected via a mechanical coupling, wherein the mechanical coupling can be effected both directly and indirectly. The direct or direct mechanical coupling can be effected in such a way that the luminous element 1, the sensor 2 and the signal lamp 3 are merely clipped directly on the carrier element 4 for the mechanical coupling, for example, and / or the mechanical coupling is effected merely by contacting the respective components on the carrier element 4. In the case of indirect or indirect mechanical coupling, additional means, preferably fastening means such as component carriers, can be provided in order to mechanically couple the respective components to the carrier element 4.The lighting element 1 consists of at least one first lighting means. An LED and / or an LED module can preferably be used as the lighting means. In addition, the lighting means can have asymmetrical light inserts in order to asymmetrically emit the light. As shown in FIG. 6, the asymmetric radiation 11 can, for example, irradiate specific regions of a parking space, with other regions being less and / or not irradiated, as a result of which the efficiency of the light emission can be increased. Particularly preferably, the lighting means has separately controllable light regions, as a result of which specific light regions can be controlled in a targeted manner depending on the requirement.The sensor 2 can detect the occupancy state of a parking lot via at least one sensor element. The sensor element is preferably an ultrasonic sensor, but can also be an optical sensor, e.g. a distance sensor. The sensor element is not limited to a specific type of sensor as long as the sensor element or the sensor elements can detect the occupancy state of the parking lot. It can also be provided that a combination of different sensor elements can be provided for the sensor 2. The sensor 2 can generate a signal according to the detected occupancy state, which preferably has the states "free" for a free parking space and "occupied" for a occupied parking space. It can also be provided that the sensor 2 can generate signals different from the occupancy state of the parking lot, e.g. in order to determine a position of an object.The signal lamp 3 for indicating the occupancy state of the parking lot detected by means of the sensor has at least one illuminant, preferably at least two illuminants, very particularly preferably 5 illuminants. These lighting means are preferably designed such that they can display different colors for different occupancy states. An input of the signal lamp 2 can receive the signal generated by the sensor 2 and advantageously the colour green is displayed for the occupancy state "Free" and the colour red for the occupancy state "Occupied". The lighting means are preferably LEDs and / or LED modules.Sensor 2 and signal lamp 3 can be embodied and provided separately, but can also form a unit 5. Preferably, the unit 5 is designed such that it is tightly sealed with respect to the environment, particularly preferably moisture-tight, in particular such that function-filling components (e.g. electrics, sensor elements) are protected. In order that the unit 5 can be supplied with electrical power, the unit 5 can have an external access via which both sensor 2 and signal light 3 can be supplied with electrical power.The carrier element 4 is preferably of elongate configuration. Furthermore, the carrier element 4 can preferably be formed in multiple parts. It is very particularly preferably designed as a wire rail. The support member 4 may include a rail 41, a housing 42, an intermediate member 43, and a cover 44 (see FIGS. 3 and 4 ). The housing 42, the intermediate element 43 and the cover 44 can also constitute a part of the illumination system 10; for example, a housing of the illumination system 10, which also encloses the carrier element, at least partially. The rail 41 can be mounted on a ceiling 45 and mechanically connected to the housing 42 via locking noses, for example. The intermediate element 43 can latch on the housing 42 via latching noses located on the wall of the housing 42. The cover 44 can then latch on the intermediate element 43 via projections located on the intermediate element 43, whereby the intermediate element 43 and cover 44 define a preferably environmentally dense, particularly preferably moisture-proof space 46. The illumination system 10 can thus be provided in this way or in another way in a sealed manner towards the outside.As shown in FIGS. 3, 4 and 5, the lighting system can have an electrical line arrangement which is preferably fastened to the carrier and can particularly preferably run in the space 46. Because the lighting system 10 or the space 46 is preferably sealed off from the outside in a sealed manner, the electrical line arrangement can be sealed off effectively, preferably according to the protection class IP65. The electrical line arrangement can electrically couple the sensor 2 and the signal lamp 3 on the one hand and / or the lighting element 1, i.e. for example couple them to an external current source in order to supply the lighting element 1, the sensor 2 and the signal lamp 3 with power. The electrical line arrangement preferably has a first electrical line arrangement for electrically coupling sensor 2 and signal lamp 3 and a second electrical line arrangement for electrically coupling luminous element 1, i.e. sensor 2 and signal lamp 3 on the one hand and luminous element 1 on the other hand can be operated in parallel. Alternatively, the electrical line arrangement can also have a common electrical line for electrically coupling sensor 2, signal lamp 3 and luminous element 1, wherein sensor 2, signal lamp 3 and luminous element 1 can be operated, for example, in series.Furthermore, the illumination system 10 can have control elements, by means of which the signal exchange between sensor 2 and / or signal lamp 3 and / or luminous element 1 can take place. The control elements preferably have control lines and a control. The control lines can be connected to a central and / or decentralised control. In particular, the signal generated by the sensor 2 with respect to the occupancy state of the parking space can be transmitted via the control lines and via the controller, in order to control, for example, the lighting means of the signal light according to the occupancy state detected by means of the sensor. In addition, further signals can also be transmitted via the control lines and / or the controller, e.g. signals for controlling the lighting element 1 and / or the lighting means (on / off, brightness etc.) and / or the separately controllable light regions of the lighting means of the lighting element 1 and / or control signals between sensor 2 and lighting element 1.As shown in FIG. 3, the unit 5 or sensor 2 and signal lamp 3 can be directly mechanically coupled to the carrier 4 and / or electrically coupled to the electrical line arrangement running in the space 46. The mechanical and / or electrical coupling can be effected via a connecting element 47 provided between the carrier 4 and the unit 5. The unit 5 can be oriented with respect to the carrier 4 in such a way that the signal lamp 3 points away from the carrier 4. Sensor 2 and signal lamp 3 can also be coupled mechanically and / or electrically to carrier 4 separately from one another, i.e. not as a unit. The unit 5 or sensor 2 and signal lamp 3 can also assume any other orientation with respect to the carrier 4. Preferably, the unit 5 or sensor 2 and signal lamp 3 is coupled to the carrier 4 in such a way that a moisture-proof coupling, particularly preferably according to the protection class IP65, is obtained.FIG. 4 shows an alternative coupling of the unit 5 or the sensor 2 and the signal lamp 3 to the carrier 4. The electrical line arrangement and / or the control lines of preferably the unit 5 or the sensor 2 and the signal lamp 3 can run in the additional element 48, which can thus also be protected by the additional element 48 in a sealed, preferably moisture-proof manner with respect to the environment, particularly preferably according to the protection class IP65. The electrical and / or mechanical coupling can likewise take place via the connecting element 47.FIG. 5 shows a further exemplary embodiment for coupling the unit 5 or the sensor 2 and the signal lamp 3 to the carrier 4; thus, it is provided according to the invention that unit 5 or sensor 2 and signal lamp 3 instead of being provided on the cover 44 are now (integrally) formed with the cover 44 and are mechanically coupled via said cover to the carrier element 4. Thus, on the one hand, the unit 5 or sensor 2 and / or signal lamp 3 can seal off the space 46 and, on the other hand, space can again be saved and the assembly effort can be reduced.In particular, to improve handling, the carrier element 4 can be formed in multiple parts. The carrier element 4 can also have any number of light elements 1, on the one hand, and sensors 2 and signal lights 3 (or units 5), on the other hand.The invention further relates to a parking guidance system which has a multiplicity of the lighting systems 10 according to the invention, wherein at least one lighting system 10 can be assigned to at least one parking space. Preferably, the lighting system 10 is arranged such that the lighting element 1 is arranged in the transition region between two parking spaces P i and P i+1( cf. FIG. 2 ) and particularly preferably the lighting element 1 and / or the signal lamp 3 is arranged in the transition region between the driving lane 101 and the parking space 102 (cf. FIGS. 6 and 7 ), such that both the parking space 102 and the driving lane 101 can be illuminated sufficiently. It can thus be achieved efficiently that the area between two parking spaces, e.g. between two vehicles, is illuminated so that e.g. a person can enter a vehicle in a well visible manner. Preferably, the unit 5 or sensor 2 and / or signal light 3 is arranged centrally with respect to the parking space 102 lying obliquely underneath.The invention is not limited to the embodiments described above as long as it is encompassed by the subject matter of the following claims.
