Description

[0001] The present invention relates to a lighting system for illuminating a working area of ​​a lifting platform and to a lifting platform with a corresponding lighting system.

[0002] Motor vehicle maintenance and repairs typically take place in workshops or workshop halls, which usually have enclosed spaces. While such spaces are equipped with lighting, the repair and maintenance of motor vehicles usually requires lighting that goes beyond the standard lighting of the premises. Particularly when maintenance is performed under a vehicle lift, the presence of the lift often leads to disadvantageous shading of the areas of the vehicle being serviced.

[0003] To counteract this shadowing, the area in the hall where the lift is located is traditionally illuminated, for example, by separately connected fluorescent tubes, by mounted spotlights, or by a flashlight that a mechanic shines in the direction of the work being performed. The illumination of the lift or vehicle created by these measures is rarely sufficient. Furthermore, the lamps and spotlights listed above typically require multiple power outlets. Furthermore, the large number of lamps and spotlights in the area of ​​the lift leads to increased power consumption.

[0004] It is therefore the object of the present invention to provide a lighting system for illuminating a working area of ​​a lifting platform and a lifting platform, wherein the lighting of the working area of ​​the lifting platform is improved.

[0005] The lighting system according to the invention is defined by the features of claim 1. The lifting platform according to the invention is defined by the features of claim 22.

[0006] The lighting system according to the invention for illuminating a work area of ​​a lifting platform having at least one column has at least one lighting unit, wherein the at least one lighting unit can be arranged on the at least one column. The lighting system further has a power supply unit for supplying the lighting system with an electrical current, and a first distribution module via which the electrical current can be conducted from the power supply unit to the lighting unit, wherein the power supply unit, the first distribution module and the at least one lighting unit can be connected to one another via at least one line device, and wherein the at least one line device can be connected to the first distribution module via at least one plug connection. A particular advantage of the lighting system according to the invention is that the work area can be illuminated in a particularly simple and cost-effective manner.In addition, a lighting system is provided which is particularly easy to install on a lifting platform.

[0007] In the context of the invention, a lighting unit is understood to mean in particular one or more LEDs, a fluorescent tube, a neon tube, a lamp, a spotlight, a light bulb or another lighting device. The lighting unit preferably has an elongated shape whose length is significantly greater than its width, as is the case with a fluorescent tube, for example. The lighting unit can have a central axis that runs centrally and along the length of the lighting unit. The lighting unit can have a luminous flux of at least approximately 2000 lm, preferably approximately 4000 lm, particularly preferably approximately 4500 lm. When using multiple lighting units, the luminous fluxes of the individual lighting units can be assumed to be added together. Of course, the lighting unit can also have a luminous flux that is greater than approximately 4500 lm, so that the lighting unit has a particularly advantageous brightness.

[0008] The power supply unit that supplies the lighting system with electrical power can, for example, be a conventional safety plug (Schuko plug), which makes it particularly easy to supply power to the system according to the invention. Of course, other types of plugs can also be used as the power supply unit. The power supply unit allows the lighting system according to the invention to be easily connected to an existing power grid. Of course, the lighting system according to the invention can also be supplied with electrical power via a generator using the power supply unit.

[0009] The electrical current can be conducted from the power supply unit to the at least one lighting unit via the first distribution module. The first distribution module can also be designed such that, for example, a second and a third lighting unit or a pair of lighting units connected in parallel can be supplied with electrical current. The lighting units connected to the first distribution module can be connected to the first distribution module in a structurally simple manner, for example, via a plug connection.

[0010] The power supply unit, the first distribution module, and the at least one lighting unit can be connected to one another via at least one line device. This can preferably be done by means of a plug connection, so that the individual components of the lighting system according to the invention can be coupled and decoupled from one another in a particularly simple manner. The line device can be designed, for example, as a power cable.

[0011] The line device can be connected to the first distribution module via at least one plug connection, whereby the distribution module and the power supply unit or lighting unit can be coupled to one another in a particularly simple manner. The lighting system according to the invention can thus be plugged together particularly easily, so that structural complexity for installing the lighting system is advantageously avoided. Furthermore, the lighting system according to the invention is preferably supplied with electrical power exclusively via the power supply unit, so that no additional power connections are required and the lighting system can be connected to a power grid and installed particularly easily.

[0012] Preferably, at least two lighting units are arranged in parallel on the first distribution module. This parallel arrangement advantageously allows the at least two lighting units to be supplied with the same current.

[0013] In a preferred embodiment, it is provided that a bridge module is arranged between the first distribution module and at least one lighting unit to bridge a spatial distance. The bridge module can, for example, be designed as a comparatively long line device. Alternatively or additionally, the bridge module can also have a support strut, for example an aluminum profile for stabilization. It can be provided that at least one lighting unit is arranged on one side of the bridge module and at least one further lighting unit is arranged on the other side of the bridge module. The bridge module thus allows at least one lighting unit to be arranged at a spatial distance from the first distribution module and / or from a further lighting unit, such that a spatial area can advantageously be illuminated by the at least one lighting unit.

[0014] Preferably, sections of the bridge module can be arranged in an upper edge region of the at least one column of the lifting platform. With such an arrangement, the area illuminated by the at least one lighting unit is preferably located below the upper edge region and below the bridge module. An object to be illuminated, for example, a motor vehicle, can thus be advantageously arranged below the bridge module and simultaneously illuminated by arranging the bridge module in the upper edge region of the at least one column of the lifting platform.

[0015] In a preferred embodiment, a transformer for adjusting the voltage is arranged between the power supply unit and the first distribution module. Depending on the type of lighting units used and the way in which the lighting units are connected (in series or parallel), a different voltage is advantageous for the lighting system according to the invention. The transformer makes it particularly easy to adjust the voltage, so that on the one hand, little power is consumed and, on the other hand, the risk of fire caused by excessively high voltage is advantageously avoided. The lighting system according to the invention is therefore also particularly safe.

[0016] Preferably, a connector module is arranged on the first distribution module, designed to connect at least two lighting units in parallel to the first distribution module. The connector module can, for example, also be arranged at one end of the bridge module, so that only the two parallel-connected lighting units are advantageously connected to the connector module and, via the bridge module, to the first distribution module, so that a comparatively small number of wiring devices need to be used. Of course, it can also be provided that several connector modules are arranged on the first distribution module, for example in order to integrate several pairs of lighting units into the lighting system according to the invention.

[0017] In a preferred embodiment, it is provided that the first distribution module can be connected via the line device to a portable lighting unit and / or a bonnet lighting unit. The portable lighting unit can be designed, for example, as a hand lamp which is operated by means of a voltage of 24 V and has a luminous flux of approximately 2000 lm. Furthermore, the portable lighting unit can have a handle with a switch and can be arranged in a particularly simple manner near the lifting platform, for example in or on a motor vehicle, via at least one hook. The bonnet lighting unit can, for example, be operated by means of a voltage of 24 V and have a luminous flux of approximately5000 μm, wherein the hood light unit has a switch integrated into a handle area and also has a hook-like construction, so that the hood light unit can be arranged particularly advantageously on a lifting platform or near a motor vehicle, and in particular on a hood. The hood light unit can be arranged in a transparent or partially transparent tube, for example an acrylic tube. By being arranged in the tube, the hood light unit is advantageously protected from external contamination such as dust or oil particles, and the hood light unit is particularly easy to clean.Thanks to the portable lighting unit and the hood lighting unit, the lighting system according to the invention can thus particularly advantageously imitate light at specific points, so that the lighting system according to the invention can particularly illuminate areas in or on a motor vehicle that are not normally illuminated by external light, for example, by hall lighting. The portable lighting unit and the hood lighting unit thus illuminate an area particularly advantageously and flexibly.

[0018] Preferably, a second distribution module is arranged between the first distribution module and the portable lighting unit and / or the bonnet lighting unit, wherein the portable lighting unit and / or the bonnet lighting unit are preferably arranged on the second distribution module. The second distribution module can be arranged directly behind the transformer and / or can be designed integrally with the transformer. The second distribution module thus allows the portable lighting unit and / or the bonnet lighting unit to be arranged particularly flexibly on the lighting system according to the invention. Of course, additional lighting units can also be arranged on the second distribution module, so that the lighting system according to the invention can be expanded particularly advantageously using the second distribution module.

[0019] In a preferred embodiment, the second distribution module is connected in series with the first distribution module. By connecting the first distribution module in series with the second distribution module, the same current flows through both distribution modules, so that, for example, the current flowing through the first distribution module can advantageously be regulated by the current flowing through the second distribution module, which is connected in series upstream of the first distribution module. By connecting the second distribution module in series in front of the first distribution module, the amount of current flowing through a distribution module and thus the amount of current flowing to the lighting units arranged on a distribution module can be regulated in a particularly advantageous manner. The lighting system according to the invention can therefore particularly advantageously have lighting units with variable brightness.

[0020] Preferably, a control device, in particular one comprising a dimmer, is arranged between the first distribution module and the second distribution module. In this context, the control device can be, for example, a dimmer that regulates the intensity and timing of the lighting units. The control device can thus, for example, regulate when the lighting system according to the invention is supplied with power, thereby advantageously saving power. Furthermore, the control device enables dimming of the lighting units arranged downstream of the control device, thereby advantageously regulating the brightness of an intensity of a light source emitted by the lighting system.

[0021] Preferably, the control device can be controlled via a remote control. The remote control can be connected to the control device wirelessly or via a cable, for example. The remote control allows the control device to be controlled and regulated in a manner that is particularly convenient for the user.

[0022] In a preferred embodiment, the lighting unit and / or the portable lighting unit and / or the hood lighting unit comprise LED bulbs. Compared to incandescent bulbs, LED bulbs consume significantly less power and also generate comparatively little heat, which advantageously reduces the likelihood of a fire hazard in the lighting system according to the invention. The use of LED bulbs thus makes the lighting system according to the invention particularly safe. Furthermore, LED bulbs have a comparatively long service life, so that in the lighting system according to the invention, the lighting units advantageously need to be replaced comparatively rarely due to a defect. The lighting system according to the invention is thus designed to be particularly energy-efficient and environmentally friendly.

[0023] Preferably, the lighting system comprises a fastening means by means of which the lighting unit and / or the first distribution module and / or the second distribution module and / or the transformer and / or the connector module and / or the regulating device can be arranged on the lifting platform. The fastening means can be designed, for example, as a magnet, in particular as a magnet integrated into the respective above-mentioned component, such that the above-mentioned component can be arranged on a magnetic column or lifting platform in a particularly simple manner via the magnet. Alternatively or additionally, a fastening means can also be selected which is designed as a double-sided adhesive tape, such that the component can be arranged on the lifting platform both permanently and in a particularly simple manner.The fastening means allows the individual components of the lighting system to be arranged particularly advantageously on a lifting platform and removed again as needed. The lighting system according to the invention is therefore designed to be particularly user-friendly.

[0024] In a preferred embodiment, a diffuser for scattering and / or a film for reflecting the emitted light is arranged on the lighting unit and / or on the portable lighting unit and / or on the hood lighting unit. The diffuser can, for example, consist of a frosted glass-like screen arranged behind the lighting unit in the direction of the emitted light. The diffuser reduces the visibility of intensity peaks of the emitted light from the lighting units, so that the scattered emitted light appears particularly pleasant to the user.

[0025] In particular, a film arranged on the lighting unit for reflecting the emitted light preferentially directs the emitted light into spatial areas into which the lighting unit does not directly emit the light. The film for reflecting the emitted light thus particularly advantageously illuminates spatial areas that would not be illuminated by the emitted light alone. The diffuser and the film thus allow the lighting system according to the invention to emit the light in a particularly advantageous manner.

[0026] In a preferred embodiment, a rotatable mount is arranged on the portable lighting unit and / or on the hood lighting unit for aligning the light emitted by the portable lighting unit and / or the hood lighting unit. The rotatable mount can be configured, for example, as a pivot joint, so that the lighting unit can be aligned particularly easily by the user. The rotatable mount thus makes it particularly easy to adjust the direction in which the light is emitted.

[0027] Preferably, the portable lighting unit emits a luminous flux of at least 500 lm, preferably at least 1000 lm, particularly preferably at least 1500 lm, and / or the hood lighting unit emits a luminous flux of at least 2000 lm, preferably at least 3000 lm, particularly preferably at least 4000 lm. Comparable lighting units used for a similar purpose generally have a comparatively significantly lower luminous flux, so that the portable lighting unit, with a luminous flux of at least 500 lm, and the hood light, with a luminous flux of at least 2000 lm, are comparatively bright. The lighting system according to the invention thus provides a particularly advantageous high luminous flux.

[0028] In a preferred embodiment, an on / off switch is arranged on the portable lighting unit and / or on the hood lighting unit. The on / off switch can be arranged, for example, as a type of toggle switch on the handle of the portable lighting unit and / or the hood lighting unit, making it particularly easy for a user to operate. The on / off switch arranged on the corresponding lighting unit can thus be used to particularly advantageously and directly turn the unit on and off without affecting the power supply of the entire lighting system according to the invention.

[0029] It is preferably provided that at least four lighting units can be arranged on a lifting platform with two columns, with two lighting units in each case forming a pair of lighting units and with one pair of lighting units being able to be arranged on each column. The column can have a longitudinal axis which runs centrally along the length of the column through the column. Each pair of lighting units can be arranged on the column in such a way that the two lighting units on the column are offset from one another by approximately 90°-180° and arranged radially around the longitudinal axis of the column. It can be provided that the central axes of the lighting units and the central axis of the column of the lifting platform are arranged approximately parallel to one another. The lighting system with four lighting units can have a total luminous flux of at least 10,000 lm, preferably at least approximately 16,000 lm, particularly preferably at least approximately18000 Im, so that the lighting system has a particularly advantageous brightness.

[0030] The arrangement of the pair of light units on the column has proven particularly advantageous for illuminating the area around the lift where maintenance or repair work, for example, on a motor vehicle, is being carried out. If at least four light units are arranged on two columns of the lift, or if one pair of light units is arranged on each column, the repair area is comparatively brightly illuminated from two sides. The illumination of the repair area of ​​the lift is therefore particularly advantageous.

[0031] In a preferred embodiment, a control unit is arranged on the lighting system, wherein the control unit can preferably be controlled via an app and / or via voice commands and wherein the control unit is connectable to the Internet. The control unit can, for example, be arranged on a regulating device so that the current or voltage supply to the lighting units connected to the regulating unit is carried out by the control unit in a particularly simple manner. Since a worker certainly uses both hands during maintenance or repair work, controlling the control unit via voice commands is particularly advantageous, since the lighting system according to the invention can thus be controlled in a particularly simple manner via voice commands during a repair process. Additionally or alternatively, the control unit can be controlled via an app.This is particularly advantageous for work performed under relatively loud noise conditions and in cases where controlling the control unit via voice commands is only possible to a limited extent. Controlling the control unit via voice commands and / or an app thus enables a user to use the lighting system according to the invention particularly easily.

[0032] It is preferably provided that the lighting unit and / or the first distribution module and / or the second distribution module and / or the transformer and / or the connector module and / or the regulating device can be connected to one another via plug connections and can be modularly expanded. A plug connection consists of a male and a female connecting part, so that the above-mentioned modules or components can be connected to one another in a particularly simple manner. It can also be provided that the line device has a corresponding plug connection part, so that the above-mentioned modules can be connected to one another via the line device by means of a plug connection and can be modularly expanded. The lighting system according to the invention can thus be expanded in a particularly simple manner via the plug connection, without, for example, the need for welded or soldered connections.

[0033] According to a second aspect, the present invention further relates to a lifting platform with at least one column and at least one lighting system according to the invention, preferably according to one of claims 1 to 21, wherein at least one lighting unit of the lighting system is arranged on the at least one column. By arranging the lighting system on at least one column, in particular a spatial area in the vicinity of the lifting platform is illuminated particularly brightly in a particularly simple manner. A lifting platform configured in this way is therefore particularly advantageously suitable for maintenance and repair work, wherein the lifting platform according to the invention is particularly energy-saving and environmentally friendly with regard to the power consumption caused by the lighting system and wherein the lighting situation in the area of ​​the lifting platform can be easily adapted to the corresponding maintenance and / or repair.

[0034] Preferably, the bridge module between the first distribution module and the at least one lighting unit bridges a distance between a first pillar and a second pillar, the first pillar, the second pillar and the bridge module enclosing a space for arranging a motor vehicle. The bridge module can be arranged at an upper region of the first and second pillars, the first distribution module, for example, at the first pillar, and the at least one lighting unit, for example, at the second pillar. The distance between the first and second pillars can be adapted to the size of the motor vehicle to be arranged. The distance bridged by the bridge module between the first and second pillars depends on the distance between the first pillar and the second pillar.Thus, the lifting platform according to the invention can enclose a space for arranging a motor vehicle in a particularly simple manner, which space is particularly advantageously adapted to the size of the motor vehicle.

[0035] In the following, the lighting system according to the invention is explained in detail with reference to two figures.

[0036] Fig. Figure 1 shows the lighting system according to the invention for illuminating a lifting platform. The lighting system is supplied with electrical power via a power supply unit 20. A transformer 60, which can adjust the voltage of the lighting system, is arranged in series with the power supply unit 20 via a line device 40. The first distribution module 30, which in this case has four slots, is connected in series with the transformer 60.

[0037] A portable lighting unit 80 or a hood lighting unit 90 connected in parallel thereto is integrated into the lighting system according to the invention via the first plug-in location via a line device 40. The optional arrangement of the portable lighting unit 80 and the hood lighting unit 90 is shown in Fig. 1 represented by dotted lines.

[0038] The second and third slots of the first distribution module 30 are each connected to a lighting unit 10 via a line device 40. The two lighting units 10, in turn, form a pair of lighting units 11. The pair of lighting units 11 can be arranged, for example, on a column of a lifting platform, with the respective lighting units 10 offset from one another by 90° to 180°. Such an offset arrangement of the two lighting units 10 allows an area arranged radially around the column of the lifting platform to be particularly advantageously illuminated by the lighting units 10.

[0039] The fourth slot of the first distribution module 30 is connected to a connector module 70 via a line device 40 and a bridge module 50. The bridge module 50 can be designed, for example, as an aluminum profile in which the line device 40 is guided. Optionally, the bridge module 50 can also be designed as a line device with a length adapted to an existing support. Furthermore, the bridge module 50 can bridge a distance between a first and a second column. In this case, for example, the first pair of lighting units 11 can be arranged on the first column and the second pair of lighting units 11 on the second column. The second pair of lighting units 11 is arranged on the connector module 70 and also consists of two lighting units 10.

[0040] The illustrated embodiment of the lighting system 1 according to the invention is thus particularly advantageously suitable for a lifting platform with two columns, wherein a pair of lighting units 11 is arranged on each column.

[0041] Fig. 2 shows a further embodiment of the lighting system 1 according to the invention, comprising a power supply unit 20, a transformer 60, and a first distribution module 31, on which a hood lighting unit 90 is arranged via a first slot and a portable lighting unit 80 is arranged via a second slot. The arrangement is effected via a line device 40. The fourth slot of the second distribution module 31 is connected in series to a regulating device 100, which in turn is connected in series to the first distribution module 30. The regulating device 100 can be configured, for example, as a dimmer that can be controlled via a radio remote control. The current or voltage to the first distribution module 30 can be regulated in a particularly simple manner via the regulating device 100.

[0042] At the first distribution module 30, which according to Fig.2 has three slots, a lighting unit 10 is arranged at each of the first and second slots, which together form a pair of lighting units 11. Such a pair of lighting units 11 can be arranged, for example, on a column of a lifting platform.

[0043] A bridge module 50 is arranged serially via a line device 40 at the third slot of the first distribution module 30. At the end facing away from the first distribution module 30, the bridge module 50 has a connector module 70. Two lighting units 10 are connected to the first distribution module 30 via the connector module 70, whereby the two lighting units 10 form a second lighting unit pair 11. The second lighting unit pair 11, like the first lighting unit pair 11, can be arranged on a column of the lifting platform.

[0044] The respective lighting units 10 of the lighting system 1 according to the invention are always connected to the respective modules in a particularly simple manner via plug connections, so that the lighting system 1 is advantageously supplied with power only via the one power supply unit 20. Due to the simple modular design of the lighting system 1 according to the invention, it can be supplemented in a particularly simple manner with additional lighting units 10 or, for example, portable lighting units 80 or hood lighting units 90.

[0045] It can further be provided that the lighting system 1 according to the invention is also used for lifting platforms with more than two columns. Since the lighting system 1 according to the invention is exclusively wired, the lighting system 1 according to the invention is particularly advantageously suited for lighting units 10 with a comparatively high luminous flux of several thousand lm. Thus, the lighting system 1 according to the invention can illuminate a lifting platform particularly advantageously, so that maintenance and / or repair work on a motor vehicle arranged on the lifting platform can be carried out under particularly advantageous lighting conditions.
