YOUR REF DATE Applicant: AVS Verkehrssicherung GmbH, Burghof 1, D-51491 Overath Title: Warning light device with energy storage, system, energy storage, traffic engineering product and use The invention relates to a warning light device for traffic safety in road traffic, according to the preamble of patent claim 1. In particular, the warning light device has an electrical lighting device, a housing, an energy storage device for supplying the lighting device with electrical energy and an energy storage holder adapted to the energy storage device, wherein the design of the energy storage device corresponds to the design of a lantern battery of type 4R25 and / or is compatible with this.The invention is further directed to a system in connection with the warning light device of the type mentioned, to an energy storage device, as can preferably be used with such a warning light device, to a traffic engineering product with a base and a stand (e.g. a beacon), and finally to a use of the said products for traffic safety in road traffic. Warning beacons and / or barriers are often used as barrier devices in traffic engineering or in road traffic, i.e. for traffic safety. They can be used to secure construction sites in road traffic, particularly on motorways, in the countryside, in cities and / or around buildings. Components of such barrier devices often include a warning light or warning light device with an energy storage device or a battery. The warning light device is also popularly referred to as a construction site lamp.The warning light device is not connected to a power grid, but is supplied with electrical energy by a compact energy storage device, for example in the form of a 4R25 lantern battery, so that the lighting device can illuminate or light up. When a warning light device is switched on, the lighting device it contains typically flashes or illuminates with decreasing brightness over time, particularly until the installed energy storage device is discharged. A large number of warning light devices are often in use on a construction site. Their energy storage device only has a limited service life, which can typically only be roughly estimated during operation. Since it is important to continually check the proper function of the warning light devices orTo ensure the correct functioning of the lighting system, a daily inspection of the construction site is required by law to check the lighting systems. Usually, the brightness of the lighting system is checked using the purely subjective standard of the human eye to determine whether the energy storage device needs to be replaced. Replacing the energy storage device at set intervals is also an option. This inevitably requires a high level of personnel expenditure. It also often happens that energy storage devices are replaced even though they actually still have a sufficiently high residual energy content and could therefore remain in use longer. A human inspection or check several times a day to determine whether warning lights are still in a defined location and whether their respective brightness is still sufficient is time-consuming.If the warning light device is no longer in its intended location due to external influences (wind, construction site employees, accidents, external influences, etc.), this fact is usually only detected when someone is on site. A warning light that has fallen over or is lying in a ditch does not adequately secure the construction site and thus increases the risk of accidents for all road users. Against this background, one object of the invention is to provide solutions that improve traffic safety. In particular, a warning light device, an energy storage device, a traffic technology product and a use are to be specified that are improved in terms of autonomy, maintenance effort, resource conservation and reliability. In particular, the disadvantages of the prior art are to be avoided or at least substantially reduced. This object is achieved with the features of the independent claims.Advantageous embodiments are specified in the subclaims and in the description. The object of the invention is achieved with a warning light device for traffic safety in road traffic, with ^ an electrical lighting device, ^ a housing, ^ an energy storage device for supplying the lighting device with electrical energy, and ^ an energy storage holder provided in the housing and adapted to the energy storage device, ^ wherein the design of the energy storage device corresponds to the design of a lantern battery of type 4R25 and / or is compatible with this, in which ^ the energy storage device has or is provided with an electronic control device and at least one secondary cell, and in which ^ the control device is designed to provide a nominal output voltage of the energy storage device of 6 volts ± 1 volt. In other words, a warning light device, e.g.a construction site lamp, which has a lighting device, in particular with a light or lamp, a housing for an energy storage device in the form of a lantern battery and the energy storage device. In addition to a rechargeable secondary cell, the energy storage device has or is equipped with an electronic control device. The control device is not merely electrical, but electronic in design in order to be able to reliably provide, for example, the nominal output voltage of the energy storage device in the range of 5 to 7 volts, in particular in a controlled or regulated manner. The control device can have a circuit with electronic control components for this purpose. Thanks to the invention, a warning light device is provided which is cost-effective to maintain.Their rechargeable secondary cell (battery) can be recharged, so that no new energy storage device has to be purchased and inserted into the warning light device if the energy provided by the energy storage device initially used is not or no longer sufficient for sufficiently bright operation of the lamp. There is therefore no need to dispose of the energy storage device after a single discharge. A particular advantage is that the energy storage device has a - at least essentially constant - nominal output voltage of between 5 and 7 volts, in particular 6 volts, which enables largely constant brightness and / or continuous operation of the lighting device over a longer period of time. While previously known lantern batteries have a nominal output voltage that typically drops over their operating time, whereby the lighting device becomes darker or brighter over the course of operation.can become too dark, the control device provided according to the invention ensures that the output voltage remains constant at the desired voltage level even after a longer period of use. In particular, the control device provides a diverse basis for better operation of the energy storage device compared to the previously known or commercially available lantern battery with 6 volts and the 4R25 design. The electronic control device can advantageously have in particular a computer or an electronic data processing system. For example, the control device can be programmable in order to control, regulate or otherwise monitor the operation of the lighting device. The control device can have a microcontroller or computer or be formed by such a computer. The control device can be designed to be programmable.The control device can comprise, in particular, a printed circuit and / or control components, in particular have or use them, for example at least one data memory, a processor and / or a microchip. The control device or the microcontroller can also comprise a variety of other components, which are in particular integrated or arranged alongside them. For example, the control device or the microcontroller can comprise a battery management system, a communications module, a means for detecting an ambient condition, a location sensor and / or a gateway. Thus, the warning light device or the energy storage device can be improved with the control device with little effort and, in particular, can be programmable, which also improves traffic safety.In the context of the present disclosure, "electrical" is essentially understood to mean the attribute of electrification, i.e., the ability to conduct electrical current in a directed manner, for example, to and from a consumer. Furthermore, "electronic" is understood to mean, in particular, the attribute of enabling data processing, further data processing, and / or programming, for example, with the aid of circuits in which at least one component functions due to vacuum or semiconductor conduction. The electrical lighting device typically has at least one illuminant, for example, an incandescent lamp and / or an LED. The electrical lighting device can illuminate, in particular as long as an electrical voltage of preferably approximately 6 volts is applied and a corresponding current is available for the illuminant.In particular, the lighting device is designed to flash intermittently, provided the lighting device is supplied with electrical energy, for example by means of an interval circuit for flashing. The interval circuit can be implemented as part of the control device or alternatively as a separate circuit which is, for example, permanently integrated into the housing. The housing can hold, accommodate and / or enclose the lighting device. The housing expediently has a holder for the lighting device. The housing has an energy storage holder adapted to the energy storage device, which is designed in particular as a recess and / or to match the 4R25 design of an energy storage device. The housing has in particular conductors and / or contacts for contacting the energy storage device, and in particular for transmitting the electrical energy provided by it to the lighting device.Preferably, two energy storage devices can be provided, particularly preferably exactly two energy storage devices. In this case, one energy storage device can be designed according to the invention or have the control device, while the other energy storage device(s) then need not have a control device (or at least not a specially assigned one). Thus, an energy storage device according to the invention and, in addition, at least one commercially available and / or electronics-free battery can be provided, in particular a lantern battery of the type 4R25. The warning light device or the housing can be designed to accommodate exactly two energy storage devices with a design of a lantern battery of the type 4R25 or compatible therewith. The energy storage holder can also be designed accordingly, or a corresponding number of energy storage holders - e.g., two of them - can be provided.It is sufficient if at least one of two energy storage devices has the control device, because this alone can comprehensively improve the warning light device. The energy storage device has the design of a lantern battery and / or is configured accordingly. The lantern battery is also known as a type called 4R25. Type 4R25 is standardized in DIN EN IEC 60086-2 with the issue date 2022-12-00. In particular, the energy storage device has a block-shaped form. The dimensions of the energy storage device - especially apart from the contacts or poles - preferably include a side length of 65 mm ± 10%, a further side length of 65 mm ± 10% and / or a height of 100 mm ± 10%. In particular, the base area of ​​the energy storage device is at least substantially square.A battery suitable for the 4R25 design as a replacement for a 4R25 lantern battery is shown, for example, in DE202019101434U1, although this battery does not fully meet the dimensions standardized or recommended in DIN EN IEC 60086-2. In particular, the proposed energy storage device does not necessarily have to have the dimensions of a 4R25 lantern battery, as the energy storage device can be smaller or designed differently. The energy storage device typically has at least two contacts or poles to provide the nominal output voltage of approximately 6 volts or 6 volts ± 1 volt. An electrical connection can be made via spiral-shaped spring contacts, in particular, which are arranged, for example, opposite a base surface and / or on a top surface. In particular, a negative pole is arranged approximately centrally on the top surface and / or a positive pole is arranged at an edge or in the region of a corner on the top surface.In particular, the energy storage device is designed such that it can replace a 4R25 lantern battery in terms of its dimensions and / or from an electrical point of view with regard to the placement of the contacts or poles and / or from an electrical point of view with regard to the output voltage at 4R25 of 6 volts. In this respect, the energy storage device should fit into 4R25 energy storage holders and its contacts or poles should be suitably positioned for 4R25 energy storage holders and the nominal output voltage of approximately 6 volts should be provided when using the control device provided according to the invention. The energy storage device has, for example, an energy storage housing, in particular with an at least substantially block-shaped form, and preferably the at least two contacts are accessible on at least one outer side. In particular, the contacts are accessible on exactly one outer side, for example on the top side.The secondary cell or multiple secondary cells can be contained in the energy storage housing, in particular fastened or accommodated therein. The secondary cell(s) is / are at least indirectly electrically connected to the contacts, preferably via the electronic control device. The secondary cell(s) is / are in particular soldered in an electrically conductive manner in order to provide the raw output voltage. It is preferably possible for one or more energy storage housings of the energy storage device to be at least partially electrically insulated or insulating. For example, the energy storage housing can comprise or consist of plastic. The energy storage housing can also be at least partially made of metal. In order to achieve electrical insulation in such a case, the housing can be covered on the inside and / or outside with an electrically insulating film and / or can be coated or painted with an insulating layer.The contacts can be designed to be accessible from the outside even if electrical insulation is present. The insulation can also improve the mechanical protection of the energy storage device against external influences, and the device can also be handled more easily and operated more safely. The secondary cell is to be understood as a rechargeable battery or accumulator. The secondary cell can preferably have a cell chemistry based on lithium ions or on lithium iron phosphate or on another basis, e.g. another cell chemistry based on lithium. The arrangement can be such that an individual secondary cell has a cell output voltage (i.e. an electrical voltage) of, for example, approximately 3.6 volts ± 0.2 volts between its two contacts or poles.In order to provide the desired 6 volts, a parallel and / or series connection of secondary cells in conjunction with at least one electrical resistor for voltage reduction can be used, and / or a DC / DC converter can be employed. The secondary cell(s) can typically be charged at an electrical voltage greater than their cell output voltage, for example with an electrical voltage 10% to 15% higher. To further improve the warning light device or the energy storage device, a battery management system for the energy storage device is provided. The battery management system can have deep discharge protection, overcharge protection, overcurrent protection, short-circuit protection, and / or a balancer.The battery management system can be integrated into the control device, for example by programming the control device and / or by a circuit in the control device. The deep discharge protection can electrically disconnect the energy storage device from consumers, in particular from the lighting device, if a certain output voltage is undershot or not reached; the said output voltage can be the nominal output voltage (e.g. applied to the at least two externally accessible contacts or poles of the energy storage device) and / or a raw output voltage (e.g. applied to the battery management system or originating from the secondary cell). The short-circuit protection can prevent a short-circuit of the at least two externally accessible contacts or poles from causing damage to or destruction of the energy storage device.In particular, the short-circuit protection prevents the energy storage device from no longer being able to provide the nominal output voltage after its contacts or poles, which provide the nominal output voltage, have been short-circuited. For example, the short-circuit protection can temporarily de-energize the contacts or poles, in particular if a resistance of less than 1 ohm, 0.5 ohms or less is detected between the contacts or poles. The short-circuit protection can thus also prevent the discharge current from becoming too high in order to protect the secondary cell(s) against excessive discharge current. This can also prevent damage. The balancer can ensure that a combination of several secondary cells in the energy storage device, in particular those connected to one another, can be discharged or charged evenly.The balancer can monitor the raw output voltage of individual or multiple secondary cells in order to always load the secondary cell(s) with the highest raw output voltage predominantly or exclusively, so that the raw output voltages of the individual secondary cells deviate from one another as little as possible, for example in the range of plus / minus or ± 2.5 volts, ± 1 volt, ± 0.5 volts, ± 0.25 volts, ± 0.1 volt or less. This ensures uniform aging and the slowest possible self-discharge of the secondary cells or the energy storage device as a whole. In a preferred embodiment of the invention, several secondary cells are provided in a series circuit and / or in a parallel circuit.The plurality of secondary cells can form an interconnection to provide a raw output voltage of more than 7 volts, preferably in the range between 7 volts and 24 volts inclusive, preferably 12 volts ± 5 volts, preferably 12 volts ± 4 volts, in particular 12 volts ± 1 volt. The raw output voltage is preferably applied directly to the interconnection. The raw output voltage results from the parallel or series connection of the individual cell output voltages. The raw output voltage can be applied directly to the control device for providing the nominal output voltage and / or to the battery management system; the battery management system can preferably be connected between the interconnection of the cells and the control device.The battery management system can also be connected to the interconnection in a parallel manner to the control device and / or integrated into the control device. If, for example, lithium-ion secondary cells are used for energy storage, a cell output voltage of approximately 3.6 volts can be expected directly from a single secondary cell, usually with a tolerance of ± 0.2 volts. By interconnecting several cells, a higher raw output voltage can be generated, for example double, triple, or quadruple 3.6 volts, i.e. 7.2 volts, 10.8 volts, or 14.4 volts. The control device and / or the battery management system can ensure that the raw output voltage of more (or less) than 6 volts, e.g. 7.2 volts, 10.8 volts, or 14.4 volts, is controlled or maintained at a value greater than or equal to 6 volts, e.g. 7.2 volts, 10.8 volts, or 14.4 volts.regulate which is as close as possible to the desired nominal output voltage of the energy storage device, for example 6 volts with a control deviation of ± 1 volt. In a particularly preferred 3S3P interconnection of secondary cells, three cells are connected in series and 3 cells are connected in parallel, so that a total of 9 secondary cells are used, with which a raw output voltage of 10.8 volts is achieved. The control device and / or the battery management system can have a DC / DC converter. The DC / DC converter is preferably provided to provide the nominal output voltage, in particular starting from a or the raw output voltage of more or less than 7 volts. The DC / DC converter is to be understood as a direct current converter or power converter. The DC / DC converter can have orconsist of a device that converts a direct voltage supplied at the input (for example the raw output voltage from the secondary cell or cells) into an outgoing direct voltage with a higher, lower or inverted voltage level (for example the nominal output voltage, which should preferably be available at the energy storage device for the lighting device). It is preferred if the energy storage device, in particular the battery management system, is designed to charge the secondary cell or the interconnection at a charging voltage of more than 7 volts, in particular 12 volts ± 1 volt. In other words, the energy storage device can, in particular automatically, pass on or connect a charging voltage or direct voltage applied to charge the secondary cell(s) to the secondary cell(s) so that a charging current can flow. The charging voltage can be applied to the contacts orPoles with the nominal output voltage can be applied, whereby the energy storage device in particular can recognize the desired charging and implement appropriate internal circuitry or switch between charging and discharging the secondary cell(s). The charging voltage can also be applied to a charging connection that is arranged at least partially separately from the contacts or poles with the nominal output voltage. In particular, the charging voltage is more than 7 volts, for example 8, 9, 10, 11, 12, 13 or more and ± 0.5 volts to enable rapid charging. The charging voltage can, for example, correspond to 1.0 to 1.2 times the raw output voltage, because secondary cells can typically be charged at a higher voltage than they output. This means that correspondingly more power can be converted for charging than with a charging voltage of just 6 volts, without the need for larger conductor cross-sections. This saves time during charging.In particular, the secondary cell and / or the interconnection has a capacity in the range between 50 Wh and 150 Wh. Preferably, between 6 and 18, for example 10 to 14, in particular 9 or 12, secondary cells are interconnected. Three secondary cells can be connected in series and a multiple of this number can be connected in parallel, for example four series circuits with three secondary cells each in parallel; in this case, twelve secondary cells are used in the interconnection. A 3S3P circuit with a total of 9 secondary cells has proven advantageous, three of which are connected in series and three in parallel. This enables a long lighting duration of a lighting device with a high nominal output voltage. Using the example of 4x3 or 3x3 secondary cells with lithium-ion cell chemistry, a cell output voltage three times higher than that of a single secondary cell can be achieved, i.e. three times approx. 3.6 volts = approx.10.8 volts. This interconnection can be charged with up to 1.2 times 10.8 volts, for example at 12.0 volts or even at 12.5 volts. It turns out that the energy storage device can be designed to be fast-charging. The battery management system can be designed to measure a raw output voltage at the secondary cell or at the interconnection. The battery management system can have a means for detecting, for example, an electrical voltage or the raw output voltage. The raw output voltage can be determined and / or monitored in order to indicate, for example, the state of charge (i.e., the remaining electrical energy content) of the secondary cell(s). The raw output voltage of the secondary cell(s) typically correlates with the state of charge, so that the state of charge can be indicated using reference values ​​of raw output voltages. The raw output voltage can be stored as a measured value orbe made available. The control device can have a location sensor to detect a location of the device, preferably GPS-supported or GNSS-supported. This makes it possible to determine whether the location of the device equipped with the location sensor corresponds to its target location. The control device can have a communication module which is provided or designed in particular for sending and / or receiving device information. The sending and / or receiving of the device information can also be understood as communication, wherein the communication can be unidirectional or bidirectional. The communication can take place with an entity separate from the communication module, in particular separate from the warning light device or the energy storage device, e.g. with a gateway.Communication can also take place with another communication module, for example with a communication module of another warning light device or another energy storage device. Communication can be wireless and / or wired. The communication module can be designed for communication via mobile radio, WAN, LoRaWAN, WLAN, Bluetooth, radio, and / or the like. This makes maintenance easier and more resource-efficient. The control device can have a means for acquiring device information, wherein the device information is in particular available digitally. The means for acquiring can, for example, measure or acquire the raw output voltage, preferably under load. The means can be a voltage sensor, a clock, a compass, an acceleration sensor, a vibration sensor, a gyroscope, a temperature sensor, a counter (e.g.for the number of charging cycles and / or energy storage changes) and / or a data memory. The means can also store and / or make available the device information, for example by electrically, in particular electronically, connecting the means to the control device, the communication module and / or the battery management system. The means can thus provide various information about the warning light device or its energy storage device and its status, which can facilitate maintenance and make resource-saving more efficient. The device information can include or have a variety of information. The device information can be assigned the following: the raw output voltage, and / or the nominal output voltage, and / or the location, and / or a time indication (e.g., the time, a switch-on time and / or a switch-on duration of the lighting device) and / or an orientation (e.g.,from the lighting device), and / or a temperature (e.g. an ambient temperature), and / or a number of charging cycles (e.g. of the secondary cell(s)), and / or a state of charge (e.g. of the secondary cell(s)), and / or a parameter (e.g. in connection with the energy storage device, e.g. an on / off switching state), and / or a traffic count, and / or an identification feature (e.g. a programmed serial number and / or a name). All of this can facilitate maintenance. The communication module can be designed for communication via a gateway, and preferably via a cloud. If several warning light devices are used to secure a traffic area, their communication modules can communicate with each other and / or the information about the energy storage devices or the warning light devices can be transmitted in a bundled manner via the gateway. The gateway can be located near the warning light device(s) orof the energy storage device or several energy storage devices, for example at a distance of 10 to a maximum of 200 m from this / these. The gateway can also be integrated into at least one warning light device, an energy storage device, a control device and / or a communication module. In this respect, a gateway energy storage device can be provided alternatively or additionally, which in particular has the gateway. The gateway can also be provided by a transmission mast, for example of a public mobile radio network. Communication is preferably carried out via a mobile radio network (in particular based on 2G, 3G, 4G and / or 5G technology) and / or via a local communication network, in particular LoRaWAN or Long-Range WAN. The communication system can further be designed to operate (also) on the basis of the Cellular V2X (C-V2X) and / or WLANp (802.11a) radio standards.11p) to enable communication with vehicles. Such communication between vehicle(s) and the infrastructure according to the invention can use the so-called PC5 interface. The technology enables the driver of a vehicle to be informed as quickly as possible about a construction site or the like where the relevant warning light device is located, as soon as the vehicle enters the reception / transmission range of the communication system and can exchange information with it. In addition to or as an alternative to the gateway, the cloud can also be provided. In particular, communication from the communication module to the cloud (and / or vice versa) can take place, preferably via the gateway, for example in order to transmit the device information, in particular in order to process the device information in the cloud. The invention enables a system which has a plurality of warning light devices. The system according to the invention can also include one or morethe gateway and preferably a cloud. In the system, the warning light devices can be designed for wireless communication with one another, e.g. via a gateway and / or directly with one another. Alternatively or additionally, a gateway can be designed for communication with the warning light devices or with their communication modules via a local communication network or a mobile radio network. In particular, the warning light devices each have a communication module. The system creates a possibility of making traffic safety even more precise, more automatable, and safer. Furthermore, an energy storage device for supplying an electrical lighting device of a warning light device for traffic safety in road traffic, in particular the described warning light device, is proposed as a solution according to the invention.This energy storage device (particularly based on the energy storage device described above - the features can be applied accordingly) is provided with or is equipped with an electronic control device and at least one secondary cell, wherein the control device is designed to provide a nominal output voltage of the energy storage device of 6 volts ± 1 volt and the design of the energy storage device corresponds to the design of a lantern battery of type 4R25 and / or is compatible with this. Thanks to this energy storage device, conventional warning light devices can be equipped with the energy storage device according to the invention instead of a lantern battery of type 4R25 in order to cost-effectively improve traffic safety. The invention creates a traffic engineering product that has a base and a stand projecting from the base.The traffic engineering product comprises the warning light device, which can be fixed or secured to the stand in a form-fitting and / or force-fitting manner, in particular at a distance of at least 0.5 m from the base. With this traffic engineering product, traffic safety can be simplified because the warning light device can be located at a clearly visible height in road traffic. Finally, as a further solution according to the invention, the use of the warning light device, the system, the energy storage device, or the traffic engineering product for traffic safety in road traffic is proposed. The energy storage device provided in each case, which has or is equipped with the electronic control device, is proposed to supply the electrical lighting device, which is also present in each case. This makes maintenance easier and conserves resources.One aspect of the invention is also seen in providing a commercially available battery, in particular a lantern battery of the 4R25 type, with an electronic control device. For example, the warning light device described is proposed, in which the energy storage device is provided by a commercially available battery or lantern battery of the 4R25 type, and in which the energy storage device is supplemented by the electronic control device, i.e. is "provided" with it. The control device can be understood as a separately manageable component which, together with a particularly commercially available and / or electronics-free energy storage device, can be introduced into a housing or energy storage holder in order to expand the functionality by means of the control device. In particular, the electronic control device is proposed as an aspect of the invention, this in particular independently ordetached from an energy storage device according to the invention. This allows commercially available warning light devices or construction site lamps to be retrofitted and improved without the commercially available energy storage device, in particular the 4R25 type lantern battery, having to be modified and / or replaced with the energy storage device according to the invention. In particular, an accumulator or a rechargeable energy storage device is proposed, which preferably has or is provided with an electronic control device and / or a communication module, wherein communication with the communication module can be carried out, for example, via mobile communications. The raw and / or nominal output voltage of the secondary cell(s) and / or the number of charging and discharging cycles can be monitored on or in the energy storage device, in particular by a battery management system, and preferably made available to service personnel via the cloud ora portal in the cloud. Thanks in particular to the energy storage device, the warning light device becomes a smart product for road safety. This allows personnel and technicians to be allocated and coordinated more effectively as needed, as they only have to be dispatched when a fault is reported and / or can plan their routes more efficiently in advance. This brings both economic and ecological advantages. In the context of the application, the abbreviation "bzw." is a short form for "beziehungsweise" and is intended to indicate alternative, essentially equivalent and / or synonymous features or terms in order to better convey the idea or meaning of a feature or term. "Beziehungsweise" can always be replaced by "und / or." Further features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention illustrated in the drawings.It shows: Fig. 1 a warning light device according to the invention with two energy storage devices in a schematic view, Fig. 2 an energy storage device of the warning light device in a perspective view, Fig. 3 one of the energy storage devices of the warning light device in a schematic side view with a view of the interior, Fig. 4 a traffic technology product with the warning light device in a schematic view, Fig. 5 a system with several warning light devices and with a gateway in a schematic representation, and Fig. 6 an alternative system with several warning light devices in a representation comparable to Fig. 5.1 shows a warning light device 1 for traffic safety, comprising an electrical lighting device 10, a housing 20, two energy storage devices 30 for supplying the lighting device with electrical energy, and, for each energy storage device 30 in the housing 20, an energy storage holder 22 adapted to the energy storage device 30. The design of the energy storage devices 30 corresponds to the design of a 4R25 type lantern battery and is compatible with it. The energy storage devices 30 each have, in a known manner, two current contacts 36 in the form of compression springs on their upper side 38. The energy storage devices are also provided with an electronic control device 40 and a plurality of secondary cells 32. The energy storage devices 30 are rechargeable. In the exemplary embodiment shown, the control device 40 is arranged inside the respective energy storage device 30.It is designed for both energy storage devices 30 to provide a nominal output voltage of 6 volts ± 1 volt. The space provided for accommodating exactly two energy storage devices 30 in the advantageous embodiment of the warning light device 1 shown can also be used such that only one energy storage device 30 according to the invention and, in addition, a conventional lantern battery, preferably of the 4R25 type, are provided in the housing 20. This is because even a single energy storage device 30 (with an electronic control device 40) improves the warning light device 1. The energy storage device 30 can replace a single lantern battery, preferably of the 4R25 type. The electronic control device 40 has at least one computer or an electronic data processing system. The control device 40 can be programmed and can monitor the operation of the lighting device 10.The control device 40 has at least one printed circuit and at least one control component, including data storage, processors, and microchips. Further components are integrated into the control device 40 or the control device 40 has them. As can be seen in particular from Fig. 3, these can be a battery management system 42, a DC / DC converter 44, a location sensor 46, a detection means 48, and / or a communication module 50. The lighting device 10 has a lighting means 12, which in the exemplary embodiment comprises a plurality of LEDs. The lighting device 10 is designed for a supply voltage or operating voltage of approximately 6 volts. The lighting device 10 is configured to flash intermittently, for example, using an interval circuit. The housing 20 partially houses the lighting device 10.A transparent pane 14 is arranged on the housing 20, which protects the illuminant 12 against environmental influences and is nevertheless translucent. The housing 20 holds the lighting device 10 with a holder. The housing 20 contains conductors 24 or contacts for contacting the contacts 36 of the energy storage devices 30. The conductors 24 lead at least indirectly to the illuminant 12. The energy storage devices 30 are connected in parallel. As can best be seen in Fig. 2, the individual energy storage device 30 has the design of a conventional lantern battery of the type 4R25 and is thus block-shaped. The energy storage device 30 has a first side length B of 65 mm ± 10%, a further side length L of 65 mm ± 10% and a height H of 100 mm ± 10%. The base area of ​​the energy storage device 30 with side lengths B and L is therefore at least essentially square. At the two contacts 36 andThe energy storage device provides a direct current with a nominal output voltage of approximately 6 volts or 6 volts ± 1 volt. The design of the contacts 36 as springs ensures that a reliable electrical connection to the conductors 24 provided in the housing is always guaranteed. As with a conventional 4R25 type lantern battery, the contact 36 forming the negative pole of the energy storage device is arranged approximately centrally on the top side 38, while the contact 36 forming the positive pole is located at an edge or in the region of a corner, in particular at least in one quadrant of the top side 38. The energy storage device 30 is thus designed such that it can replace a 4R25 type lantern battery in terms of its dimensions and, from an electrical point of view, the placement of the contacts 36 and the 4R25-typical output voltage of 6 volts. The energy storage device 30 has an energy storage housing 31 with an at least substantially block-shaped form.The energy storage housing 31 is rounded or beveled at an angle of preferably 45° on its four vertical edges. From Fig. 3 it can be seen that the secondary cells 32 are accommodated in the energy storage housing 31, wherein they are preferably fastened therein, for example by means of adhesive and / or a surrounding, hardening potting compound in which the cells are embedded. It is also possible to reliably hold the secondary cells 32 in the housing 31 by means of a suitable holding device and / or to mechanically clip them together with securing clips (not shown), thus making replacement easier. The secondary cells 32 are electrically connected to the contacts 36 via the control device 40. The secondary cells 32 are electrically connected to one another and to the control device, in particular soldered, in order to provide the raw output voltage to the control device 40.The battery management system 42, the DC / DC converter 44, the location sensor 46, and the detection means 48 are parts of the control device 40 or are integrated into it, for example as a microcontroller, as a printed circuit, and / or on one or more circuit boards. The arrangement can preferably be such that the battery management system as such is located on its own circuit board and thus separate from the control unit provided on a second circuit board. The two circuit boards can then preferably be connected to one another by means of connectors. The control device 40 is programmable. The battery management system 42 has deep discharge protection, short-circuit protection, and a balancer, and in a preferred embodiment, also has overcharge protection, short-circuit protection, and overcurrent protection.In the preferred embodiment explained above, the two circuit boards can be arranged one above the other, whereby the upper circuit board can then have contact points for a direct electrical connection to the spring contacts of the energy storage device 30, which is arranged in the housing below the circuit boards. In the exemplary embodiment shown, four secondary cells 32 are connected in series to form an interconnection 34, thus providing a raw output voltage of 14.4 volts (± 1 volt). This raw output voltage is applied directly to the control device 40. The control device 40, in turn, or the battery management system, ensures that the raw output voltage of 14.4 volts supplied by the interconnection 34 of the secondary cells 32 is reduced at the contacts 36 in a controlled or regulated manner to the desired nominal output voltage, i.e., to 6 volts (± 1 volt) in the present preferred exemplary embodiment.This is achieved by means of the DC / DC converter 44, which reduces the raw output voltage to as constant a 6 volts as possible, regardless of the level of the raw output voltage. The control device 40 of the energy storage device 30 or the battery management system 42 is designed to charge the secondary cell 32 or the interconnection 34 at a charging voltage of more than 7 volts. The energy storage device can therefore be charged at a charging voltage of more than 7 volts, for example at a charging voltage of 15 volts, so that a rapid charging function is possible despite the nominal output voltage of 6 volts. Charging can take place via the contacts 36. The control device 40, in particular the battery management system 42 or the DC / DC converter 44, can detect charging in order to pass a charging current to the interconnection 34 when a charging voltage is present. The control device 40, in particular the battery management system 42 orThe DC / DC converter 44, can detect when the interconnection 34 is fully charged in order to terminate charging, for example, by interrupting the current flow at the contacts 36. This can be done based on monitoring the raw output voltage. In this way, damage due to overcharging can be avoided. The control device 40, in particular the battery management system 42 or the DC / DC converter 44, can detect when the interconnection 34 is discharged to the minimum permissible discharge state in order to terminate any further discharging, for example, by interrupting the current flow to the contacts 36. This can be done based on monitoring the raw output voltage. In this way, damage due to deep discharge can be avoided. The energy storage device 30 or the interconnection provided therein has a capacity of 100 Wh ± 10 Wh in the present case.The location sensor 46 is used to detect a location, in particular the location of the energy storage device 30, with the assistance of GPS or GNSS. The communication module 50 provided on or in the device 1 or the energy storage device 30 is designed for bidirectional and wireless communication or for sending and receiving, in particular, digital device information. Communication can take place via LoRaWAN. In this case, communication can take place with an entity located away from the communication module 50, in particular away from the warning light device 1 or the energy storage device 30, e.g., with a gateway G. Communication can also take place with another communication module 50, for example, with a communication module 50 of another warning light device 1 or another energy storage device 30. The control device 40 has a means for detecting 48 one or more device information items.The means 48 comprises a voltage sensor for measuring the raw output voltage, a clock, a vibration sensor, a gyroscope, a temperature sensor, a charging cycle counter, and a data memory. The means 48 can store and make available the device information, wherein the means 48 is connected in particular to the communication module 50 and the battery management system 42. In the present case, the device information comprises at least the raw output voltage, the nominal output voltage, the location of the energy storage device, time information, an ambient temperature, a charging cycle number of the secondary cells 32, a charge state of the secondary cells 32, and an identification feature. The charge state can be indicated in particular based on the raw output voltage, especially when the lighting device is switched on or illuminated.In particular, all components (battery management system 42, DC / DC converter 44, location sensor 46, means 48, and communication module 50) of the control device 40 are at least indirectly connected to one another. Fig. 4 shows a traffic engineering product 100 having a base 102 and a stand 104 extending from the base 102. The traffic engineering product 100 has a warning light device 1, wherein the warning light device 1 is positively and non-positively secured to the stand 104 at a distance of at least 0.5 m from the base 102. The warning light device 1 has two energy storage devices 30, one of the energy storage devices 30 having an electronic control device 40. In other words, a warning beacon of known design is shown, in which the warning light device used is not equipped with two conventional 4R25 lantern batteries, but at least with an energy storage device 30 (according to the invention).The warning beacon therefore uses a warning light device 1 according to the invention, as shown, for example, in Figs. 1 to 3 or described above. Not shown is a variant of a traffic engineering product 100 in which the base 102 and the stand 104 are formed as one piece. In other words, the base 102 and the stand 104 do not have to be two separate parts. The base 102 can also be understood as an underside or as a side of the stand 104 for setting up on a surface. Fig. 5 shows a system with three warning light devices 1, each of which has a communication module 50, and with a gateway G. The gateway G in the present case is a computer that is placed in a common traffic area 200 with the warning light devices 1 and is designed for wireless communication with the communication modules 50 of the warning light devices 1. In this respect, a local communication network orA radio network is provided via which the components arranged in the traffic area 200 can communicate with each other. The gateway G can thus collect the device information provided by the communication modules of the devices 1 and forward it to a cloud C, separate from the traffic area 200. Data processing can take place in the cloud C, for example, to determine a maintenance requirement or to determine whether the warning light devices 1 are correctly positioned in the traffic area 200. The cloud C can also be part of the system. Fig. 6 shows another system with three warning light devices 1, each having a communication module 50.In this exemplary embodiment, a gateway G is formed by a transmission mast of a public mobile radio network, which is located at a distance from the traffic area 200 with the warning light devices 1 and which can communicate wirelessly with at least one of the warning light devices 1. For this purpose, at least one of the warning light devices 1 of the system is equipped with mobile radio capability. The warning light devices 1 can communicate with each other wirelessly, e.g., via Wi-Fi, Bluetooth®, or NFC. Thus, one of the warning light devices 1 can send the device information of all devices in the system collectively to the gateway G and forward it to a cloud C, which is also arranged separately from the traffic area 200. Data processing can take place in the cloud C, for example, to determine a maintenance requirement or to determine whether the warning light device 1 is correctly positioned in the traffic area 200.In both embodiments according to Fig. 5 and Fig. 6, the communication modules 50 are designed for communication via the gateway G and via the cloud C. The communication modules 50 of the individual devices can communicate directly with each other. Communication is possible via a local communication network, in particular LoRaWAN or Long-Range WAN. Communication is also possible via the mobile radio network, based on 2G, 3G, 4G and / or 5G technology depending on availability or signal strength. The device information can preferably be made available to service personnel via the cloud C or via a portal in the cloud C. The warning light devices 1 can thus be monitored remotely for maintenance requirements and the need for action. For example, immediate action can be taken if a warning light device 1 is inoperative, has fallen over, or has been stolen. Fig. 5 and Fig.6 each show a use of the warning light device 1, the system, or the energy storage device 30 for traffic safety in road traffic, specifically in a traffic area 200 from road traffic. In practice, several traffic technology products 100, each with at least one energy storage device 30 in a warning light device 1, can be provided distributed in a traffic area 200, as illustrated, for example, in Fig. 5. The traffic area 200 can, for example, be a multi-lane road on which one of the lanes is blocked off with the traffic technology products 100, wherein the included lighting devices 10 generate a flashing light in the blocked-off lane. The traffic technology products 100 are each assigned a predefined (target) location. The (target) location should remain as unchanged as possible for the duration of the blocking.Here, a location sensor 46 in each energy storage unit 30 can detect the current (actual) location of each traffic technology product 100 and communicate wirelessly via a nearby gateway G or to the gateway G, for example via a LoRaWAN or WLAN. The gateway G can bundle all locations and continuously forward them to a cloud C, for example as device information. Service personnel also have access to the cloud C. A portal is available in the cloud that is designed to be accessible externally. The portal displays the locations, in particular all device information that has been or is being communicated by the energy storage units 30. The portal then shows whether an energy storage unit 30 is in an undesirable location or whether an energy storage unit or the traffic technology product 100 has fallen over.In particular, the portal can issue a warning message if an actual state of device information deviates from a desired state of the device information. The warning message is typically communicated to service personnel in real time so that rapid action can be taken to restore the desired state. Service personnel can also be informed as soon as the charge level of an energy storage device 30 is so low that charging or replacing the energy storage device 30 is necessary. Ultimately, and in other words, the invention serves the scenario in which a traffic engineering product 100 with the warning light device 1 has fallen over, for example, in a storm or an accident. The installed location sensor 46 transmits, for example, a signal indicating the change in the state (location, position, vibration, etc.) wirelessly within the traffic area 200, e.g.via LoRaWAN or Wi-Fi, to a mobile radio-capable (main) warning light device 1 and / or to the mobile radio-capable gateway G. This sends the status change to the cloud C or to a control center with service personnel, where the warning message is issued, in particular with prioritization according to the ensuing danger. The warning message can be issued acoustically and / or visually. An employee is then given a work order to properly reposition and / or repair the traffic technology product 100. This work order can be prioritized depending on the urgency. The employee can also check whether the charge level of the respective energy storage device 30 and in particular of other energy storage devices 30 in the vicinity is still sufficient for continued scheduled operation or whether a replacement—if the employee is already on site—is expedient or economical.
