Description

[0001] The invention relates to a lighting system for a two-wheeled vehicle, in particular a bicycle or an electric bicycle, wherein the two-wheeled vehicle comprises a frame with a head tube and a front wheel fork rotatably mounted in the head tube, which front wheel fork is connected to a tubular handlebar via a stem.

[0002] A lighting system is an important feature for a bicycle or electric bicycle (e-bike), especially in poor lighting conditions or at night. The lighting ensures that the bicycle and cyclist are clearly visible to other road users, thus contributing significantly to road safety.

[0003] For bicycles or e-bikes without pre-installed lights, it's possible to retrofit lighting. This typically involves a front light and / or a rear light. The front light is often mounted on the handlebars or the front part of the frame or fork, while the rear light is often mounted on the saddle or the rear part of the frame.

[0004] Modern lighting systems are usually powered by batteries or rechargeable batteries, which can be inserted in a replaceable battery compartment in the front or rear lighting or, in the case of rechargeable units, can also be permanently installed.

[0005] Against this background, the object of the present invention is to improve and / or further develop existing lighting solutions with regard to several aspects by providing a lighting system that can be retrofitted or permanently installed on a two-wheeled vehicle, in particular on a bicycle or e-bike, which is optimised in particular with regard to attachment and / or integration on the two-wheeled vehicle, with regard to illumination and visibility for other road users and thus road safety, with regard to the design and coordination of several lighting devices with one another, user-friendliness, in particular when switching on or off and / or when charging, and / or with regard to the appearance when installed.

[0006] To achieve this object, the invention discloses a lighting system for a two-wheeled vehicle, in particular a bicycle or electric bicycle, wherein the two-wheeled vehicle comprises a frame with a head tube, and a front wheel fork rotatably mounted in the head tube, which is connected to a tubular handlebar via a stem.

[0007] The lighting system comprises a first lighting device for mounting on a first front end of the tubular handlebar.

[0008] The first lighting device has an inner section and an outer section connected thereto. The inner section can be inserted axially into the interior of the tubular handlebar at the first end of the tubular handlebar. The outer section projects axially beyond the first end of the tubular handlebar when the first lighting device is in the operating state, in particular when the inner section is inserted axially into the interior of the tubular handlebar at the end of the tubular handlebar.

[0009] Preferably, the lighting system further comprises a second lighting device for mounting on a second front end of the tubular handlebar.

[0010] The second lighting device can preferably correspond to the first lighting device in some aspects. In principle, features that are generally described below for a lighting device are applicable to the first lighting device and / or the second lighting device, provided a second lighting device is included and unless otherwise specified.

[0011] If a second lighting device is included, this also has an inner section and a connected outer section. The inner section can be inserted axially into the interior of the tubular handlebar at the second end face of the tubular handlebar. The outer section projects axially beyond the second end face of the tubular handlebar when the second lighting device is in the operating state, in particular when the inner section is inserted axially into the interior of the tubular handlebar at the second end face of the tubular handlebar.

[0012] The first lighting device and / or the second lighting device can be designed in particular for subsequent and / or detachable mounting on a standard bicycle handlebar.

[0013] The lighting system according to the invention is intended in particular for a two-wheeled vehicle with a crank and / or pedal arrangement, in particular for a two-wheeled vehicle that can be driven exclusively by muscle power or additionally by muscle power, i.e. in particular a bicycle that can optionally include an electric motor (so-called e-bike or pedelec). The frame, i.e. the supporting structure, of the two-wheeled vehicle therefore comprises in particular a bottom bracket shell for receiving a bottom bracket for a crankset with pedals. The frame of the two-wheeled vehicle further comprises in particular a down tube, which is connected on the one hand to the head tube and on the other hand to the bottom bracket shell. Furthermore, the frame of the two-wheeled vehicle comprises in particular a seat tube, which is provided for receiving a saddle.

[0014] In the assembled state, the inner section of the first lighting device and / or the second lighting device is inserted into the interior of the tubular handlebar. The inner section is, in particular, completely inserted into the interior of the handlebar, so that the entire inner section is radially surrounded by the tubular handlebar. In the assembled state, the outer section can preferably protrude axially beyond the front end of the tubular handlebar. In particular, when the lighting device is in the operating state, the outer section protrudes axially beyond the front end of the tubular handlebar.

[0015] The inner section and the outer section of the first and / or second illumination device define in particular the shape of the illumination device in radial terms.

[0016] Accordingly, the inner section of the first and / or second lighting device can have an inner section diameter that is, in particular, smaller than the diameter of a standard bicycle handlebar in the grip area. A standard bicycle handlebar is to be understood, in particular, as a commercially available bicycle handlebar.

[0017] The outer section of the first and / or second lighting device can have an outer section diameter that is larger than the inner section diameter. Accordingly, the outer section can radially project beyond the inner section and / or radially project beyond the diameter of a standard bicycle handlebar in the grip area.

[0018] The first and / or second lighting device can further comprise a radial collar, which forms a transition between the inner section and the outer section and / or forms a transition between the inner section diameter and the outer section diameter. Such a radial collar can, for example, be designed to have a stepped shape in an axial section. The radial collar can be designed to engage the front end of the tubular handlebar when the inner section is inserted into the interior of the tubular handlebar.

[0019] In radial terms, the outer section diameter can thus be larger than the inner section diameter. However, it is not fundamentally impossible for the outer section diameter and the inner section diameter to be identical, or for the outer section diameter to be smaller than the inner section diameter. As described, however, the outer section protrudes axially beyond the front end of the tubular handlebar, particularly when the lighting device is in the mounted state and / or in operation.

[0020] Preferably, the first and / or second lighting device comprises means for mounting on the front end of the tubular handlebar.

[0021] The mounting means may comprise one or more screw holes in the radial collar of the lighting device. Such screw holes may, for example, extend through the radial collar and into the outer portion, so that screws can be screwed into such screw holes to mount the lighting device.

[0022] The mounting means may further comprise a fastening body, which can be fastened, on the one hand, to the tubular handlebar and / or to a handlebar grip, and, on the other hand, can be fastened directly or indirectly to the lighting device. Such a fastening body can, in particular, be designed as a fastening ring.

[0023] For example, the fastening body can be designed to be clamped to the tubular handlebar, and the lighting device can be designed to be screwed directly to the fastening body, such that the lighting device can be fastened to the fastening body with one or more screws, wherein the lighting device preferably rests against the fastening body in the fastened state. However, indirect fastening is also possible. For example, the lighting device can first be fastened to another element, and the other element can in turn be fastened to the fastening body.

[0024] A fastening body which is designed as a fastening ring or comprises a fastening ring can in particular have a device for varying the circumference in order to clamp the fastening ring, preferably from the outside, to the tubular handlebar.

[0025] The fastening body can have one or more screw holes extending axially through the fastening body, such that the fastening body can be screwed to the lighting device. For example, it can be provided that the fastening body can be screwed axially through these screw holes to the screw holes in the radial collar of the lighting device.

[0026] The fastening body or fastening ring can preferably be designed as a standard clamping ring that is compatible with a standard bicycle handlebar grip system. A standard bicycle handlebar grip system is understood to mean, in particular, a commercially available bicycle handlebar grip with associated commercially available clamping rings.

[0027] It is also possible for the mounting means to comprise a device for internally fastening the lighting device to the handlebar. For example, it is possible for the inner section to be fastened from the inside in the tubular handlebar. For example, a fastening body can be included which, on the one hand, can be fastened from the inside in the tubular handlebar and, on the other hand, can be fastened or is fastened to the inner section of the lighting device.

[0028] With regard to the dimensions of the first and / or second lighting device, the following values ​​in particular can be provided.

[0029] The inner section diameter of the first and / or second illumination device may be between 10 and 20 millimeters, preferably between 15 and 20 millimeters.

[0030] The outer section diameter of the first and / or second illumination device can be between 10 and 60 millimeters, preferably between 22 and 60 millimeters, more preferably between 22 and 35 millimeters.

[0031] The inner section of the first and / or second illumination device may have an axial inner section length which is between 10 and 150 millimeters, preferably between 40 and 100 millimeters.

[0032] The outer section of the first and / or second illumination device can have an axial outer section length which is between 5 and 75 millimeters, preferably between 10 and 40 millimeters.

[0033] The technical equipment of the lighting system or the first and / or second lighting device will now be discussed in more detail.

[0034] In particular, it is provided that the first and / or second lighting device comprises lighting means. A lighting device may well comprise several lights, which can be designed, in particular, for different directions and thus for different road users.

[0035] Specifically, the illumination means of the first and / or second lighting device can comprise a front light configured to generate a front light beam, in particular one that is directed forward of the two-wheeled vehicle when mounted. Such a front light beam can preferably have an aperture angle between 30 and 160 degrees.

[0036] The lighting means may further comprise a rear light configured to generate a rear light beam, in particular one that, when mounted, is directed rearward from the two-wheeled vehicle. Such a rear light beam may preferably have an aperture angle between 15 and 80 degrees.

[0037] The lighting means may further comprise a ground light configured to generate a ground light beam, in particular one that is directed downwards from the two-wheeled vehicle when mounted. Such a ground light beam may preferably have a longitudinal aperture angle of between 20 and 130 degrees and / or a transverse aperture angle of less than 30 degrees.

[0038] The longitudinal opening angle is understood here in particular to mean an opening angle in the longitudinal direction, i.e., in a direction which, when the respective lighting device is mounted on the two-wheeled vehicle, runs from rear to front with respect to the two-wheeled vehicle. Accordingly, the transverse opening angle is understood in particular to mean an opening angle in the transverse direction, i.e., in a direction which, when the respective lighting device is mounted, runs from left to right with respect to the two-wheeled vehicle, in particular, perpendicular to the longitudinal direction.

[0039] The illumination means of the first and / or second illumination device are preferably arranged on a part of the illumination device which, in the assembled state and / or operating state, projects axially beyond the front end of the tubular handlebar, i.e. in particular on the outer section.

[0040] The first and / or second lighting device has in particular various housing parts as described in more detail below.

[0041] Preferably, the first and / or second lighting device comprises an inner housing with an inner housing sleeve and an inner housing flange connected thereto. The inner housing sleeve forms, in particular, the inner section of the lighting device.

[0042] The inner housing, which can be at least partially inserted into the interior of the tubular handlebar, is preferably connected to an outer housing which projects outwards in the assembled state.

[0043] The first and / or second lighting device comprises, in particular, an outer housing with an outer housing shell having one or more luminaire recesses and an outer housing end face. The outer housing, and optionally the inner housing flange, preferably form the outer section of the lighting device.

[0044] The above-described lighting means can, in particular, comprise one or more light sources, each with an optionally associated light shaper, wherein these are preferably mounted on a circuit board, which is preferably arranged on the inner housing flange. The one or more light sources, each with an optionally associated light shaper, in particular form the one or more luminaires of the lighting means.

[0045] It can also be provided that the first and / or second lighting device comprises a transparent, in particular one-piece, intermediate housing which is arranged between the inner housing and the outer housing.

[0046] Such an intermediate housing can, in particular, form one or more luminaire covers, which cover the one or more light sources, each with an optionally associated light shaper, and preferably engage with the one or more luminaire recesses in the outer housing shell. Such a cover for the light sources and any associated light shapers is preferably designed to be watertight, so that the light sources and any associated light shapers are protected from moisture.

[0047] The first and / or second lighting device can in particular comprise a sealing ring which is arranged between the inner housing and the outer housing and / or the intermediate housing.

[0048] In the following, we will look in more detail at the optionally several different luminaires of a lighting system in connection with the respective assigned light sources and / or light shapers.

[0049] In particular, a first light source forming the front light can be included with an associated first light shaper, wherein the first light source is designed as a light-emitting diode which has an axial emission direction, and the light shaper is designed as a reflector which deflects the axial emission direction into a radial emission direction.

[0050] In other words, the first light source can be mounted on the circuit board in such a way that it has a radiation direction perpendicular to the surface of the circuit board and an associated reflector can cause a deflection into a radiation direction parallel to the surface of the circuit board.

[0051] Furthermore, a second light source forming the rear light with an associated second light former can be included, wherein the second light source is designed as a light-emitting diode which has an axial radiation direction, and the light former is designed as a reflector which deflects the axial radiation direction into a radial radiation direction.

[0052] Again, the second light source can be mounted on the circuit board in such a way that it has a radiation direction perpendicular to the surface of the circuit board and an associated reflector can cause a deflection into a radiation direction parallel to the surface of the circuit board.

[0053] Furthermore, a third light source forming the floor lamp can be included with an associated third light former, wherein the third light source is designed as a laser diode which has a radially bundled radiation, and the light former is designed as a line former which fans out the radially bundled radiation in the longitudinal direction.

[0054] In other words, the laser diode can be mounted on the circuit board in such a way that a substantially point-like emission occurs along a direction parallel to the surface of the circuit board. A line former can then fan out the substantially point-like emission in one dimension, resulting in a substantially linear emission. This allows, for example, laser light lines to be projected onto the floor.

[0055] The aforementioned line former is preferably rotated around the radial direction at a correction angle such that the longitudinal direction of the fanning-out runs obliquely with respect to a plane extending orthogonally to the axial direction at the correction angle. The correction angle is preferably between 3 and 15 degrees.

[0056] A correction angle can therefore take into account, in particular, the fact that the tubular handlebar is inclined relative to the transverse direction of the two-wheeled vehicle.

[0057] In some embodiments, the lighting system, in particular the first and / or the second lighting device, has a charging unit.

[0058] A charging unit may preferably comprise a charging port for plugging in a charging device, wherein the charging port is preferably contacted on the or a printed circuit board, which is preferably arranged on the inner housing flange of the inner housing.

[0061] The first and / or second lighting device may also optionally comprise a cover cap for covering the charging port recess in the outer housing.

[0062] Such a cover cap may preferably comprise a flexible retaining web which is held on the outer housing and / or on the intermediate housing.

[0063] According to a further development, the charging unit can optionally comprise a coil for inductive charging and / or magnets for attaching a charging device. For example, a charging device can be magnetically attached axially to the outer housing front side to establish an inductive coupling with a coil for inductive charging.

[0064] In some embodiments, the lighting system, in particular the first and / or second lighting device, comprises a switching unit for switching the lighting means, in particular the lights of the lighting means. Such a switching unit can be configured, in particular, to switch the lighting means, in particular the lights of the lighting means, on or off, or to switch between different operating modes.

[0065] A switching unit preferably comprises a switch, in particular designed as a pushbutton, wherein the switch is preferably contacted on the circuit board or a circuit board, which is preferably arranged on the inner housing flange of the inner housing. In the context of this application, the term "switch" is to be understood as a generic term for components that can open or close an electrical circuit through user interaction.

[0066] A switching unit can preferably comprise an actuating element that is connected to the switch and can be actuated by a user to switch the switch. Such an actuating element is, in particular, mechanically connected to the switch or can be brought into contact to switch the switch. Furthermore, such an actuating element can sometimes be configured with multiple elements, with one or more actuating element elements each being mechanically connected to one another or capable of being brought into contact to transmit an actuating pulse to the switch.

[0067] Optionally, it can be provided that one or the outer housing has an actuating element recess for the actuating element and optionally one or the intermediate housing, which is arranged between the inner housing and the outer housing, has an actuating element opening for the actuating element.

[0068] A switching unit can be designed, in particular, as a shell-side switching unit, such that the actuating element is arranged on the outer housing shell, the actuating element recess is preferably located in the outer housing shell, and the actuating element opening preferably extends radially through the intermediate housing. In this case, the actuating element can be actuated, in particular, by exerting pressure in the radial direction.

[0069] A switching unit can also be designed as a front-mounted switching unit, such that the actuating element is arranged on the outer housing front side, the actuating element recess is preferably located in the outer housing front side, and the actuating element opening preferably extends axially through the intermediate housing. In this case, the actuating element can be actuated in particular by exerting pressure in the axial direction.

[0070] A front-side switching unit can, for example, comprise an actuating element with an elastically deformable disc arranged on the front side and optionally a further actuating element member which is arranged between the elastically deformable disc and the switch in order to transmit pressure pulses.

[0071] According to a further development, the first and / or second lighting device can comprise a switching unit with a switch, in particular designed as a push-button, which, when the lighting device is mounted, is directed rearward relative to the two-wheeled vehicle and can be actuated in the radial direction, in particular by a pressure pulse. Such an internal switch can be provided alternatively or additionally.

[0086] The energy storage system comprises one or more of the following energy storage devices: a first energy storage device arranged in the first lighting device, a second energy storage device arranged in the second lighting device, and / or an external energy storage device arranged outside the first and second lighting device, e.g. arranged in an additional module which can be attached, e.g., to or in the frame of the two-wheeled vehicle.

[0087] It is possible for at least one of the energy storage devices or the energy storage devices of the energy storage system to be configured jointly to operate the lighting means of the first lighting device and the second lighting device. However, it is also possible for certain energy storage devices of the energy storage system to be configured to operate certain lighting devices, for example, a first energy storage device arranged in the first lighting device for operating the lighting means of the first lighting device, and a second energy storage device arranged in the second lighting device for operating the lighting means of the second lighting device.

[0088] Furthermore, the lighting system can comprise a switching unit, in particular according to the above-mentioned embodiments, which is configured to switch the lighting means of the first lighting device and to switch the lighting means of the second lighting device by transmitting switching signals via the means for connection.

In the case shown here, each of the two lighting devices 110, 120 is configured to generate such a front light beam 130. Furthermore, one or more rear light beams 140 are directed rearward from the bicycle 1. Again, here, each of the two lighting devices 110, 120 is configured to generate such a rear light beam 140.

[0113] In addition, the lighting devices 110, 120 can also generate one or more ground light beams 150, which here are formed linearly on the ground. Specifically, such a linear ground light beam 150 can be emitted by a mounted lighting device 110, 120 such that it extends along the longitudinal direction of the two-wheeled vehicle 1. In the case shown here, each of the two lighting devices 110, 120 is again configured to generate such a ground light beam 150.

[0114] Fig. 4 shows a two-wheeled vehicle 1, here again a bicycle 1, with a frame 2 which comprises a head tube 4, and with a front wheel fork 6 which is rotatably mounted in the head tube 4 and which is connected via a stem 12 to a tubular handlebar 14 which has a handlebar grip 20 on each side.

[0115] According to one embodiment of the invention, two lighting devices 110, 120 are mounted on the two-wheeled vehicle 1, which are operable independently of one another. The lighting devices 110, 120 can, for example, be two identical or mirror-symmetrical units. Each of the two lighting devices 110, 120 is attached to a front end 16, 18 of the tubular handlebar 14. Specifically, each of the lighting devices 110, 120 is inserted into the interior of the tubular handlebar 14 and / or into the interior of the handlebar grip 20 at one of the two front ends 16, 18 of the handlebar 14, wherein the lighting devices 110, 120 are preferably only partially inserted, so that, particularly in the operating state, they still partially protrude from the interior of the handlebar 14 and / or the handlebar grip 20.

[0116] Fig. 5-6 now show in more detail the shape and attachment of the first lighting device 110, using the example of the second lighting device 120. The lighting device 110 has an inner section 200 and an outer section 300 connected thereto. The inner section 200 can be inserted into the interior of the handlebar grip 20 and / or into the interior of the handlebar bracket 14, wherein the handlebar grip 20, in turn, is attached or can be attached to the handlebar bracket 14. When the lighting device 110 is inserted and mounted, only the outer section 300 of the lighting device 110 protrudes outward from the handlebar grip 20 and / or the handlebar bracket 14.

[0117] On the outer section 300, one or more illumination devices 600 are located for generating one or more light beams. One of the illumination devices 600 is provided, for example, for generating a front light beam 130. Furthermore, in this case, a switching unit 800 is arranged on the outer section 300 of the lighting device 110 for switching the one or more illumination devices 600 on, off, or between different operating modes. Furthermore, in this case, a charging unit 700 is arranged on the outer section 300, to which a charging device can be connected in order to charge the lighting device 110.

[0118] In the example shown, the charging unit 700 is arranged on the front side of the outer section 300 and can be protected with a cover cap 390 that can also be attached and / or removed from the front side. Furthermore, in the example shown, the switching unit 800 is arranged on the casing side of the outer section 300. Of course, other arrangements of the charging unit 700 and / or the switching unit 800 are also possible.

[0119] Fig. 7-8 show some further details of the first lighting device 110 mounted on a handlebar 14 and / or handlebar grip 20. In particular, it can be seen that mounting means 500 can be used to releasably fasten the lighting device 110 to the handlebar 14 and / or handlebar grip 20. In this example, this is specifically a fastening ring 500, which on the one hand encompasses the handlebar 14 and / or handlebar grip 20 from the outside and can thus be clamped, and on the other hand can be screwed to the lighting device 110, e.g., its outer housing 300.

[0120] As shown, the cover cap 390 has a flexible retaining web 392 and is held in an opening of the outer housing 300 by this retaining web 392 to prevent loss of the cover cap 390. Furthermore, the cover cap 390 is equipped with a sealing lip 394 to ensure a secure fit and / or watertight protection for the charging unit 700.

[0121] Fig. 9-13 again show two-wheeled vehicles 1 with a frame 2, a head tube 4, a front wheel fork 6, and a stem 12 and handlebar 14. According to one embodiment of the invention, two lighting devices 110, 120 are mounted on the two-wheeled vehicles 1 shown, which are directly and / or indirectly connected to one another via connecting means 900 and thus functionally complement one another. In particular, the connecting means 900 can enable the energy storage system of the two lighting devices 110, 120 to be charged via the same charging unit and / or the lighting devices of the two lighting devices 110, 120 to be switched via the same switching unit.

[0122] The connection between the two lighting devices 110, 120 can be implemented in different ways. The lighting system can also include an additional module 950, which enables an indirect connection between the two lighting devices 110, 120 and / or can provide additional functionality. For example, an additional module 950 can have an external energy storage device 770. Several options for a direct and / or indirect connection, possibly with additional module 950, are explained below. However, these are only examples and are not intended to be exhaustive.

[0123] One possibility is that there is a direct connection 910 between the first lighting device 110 and the second lighting device 120 (see Fig. 9). Such a direct connection 910 can be established, for example, via a connecting cable, wherein the connecting cable has two cable ends, the first cable end being connected to the first lighting device 110 and the second cable end being connected to the second lighting device 120. Such a direct connection can, for example, enable a charging unit on the first lighting device 110 to also charge the second lighting device 120 and / or a switching unit on the second lighting device 120 to also switch the first lighting device 110.

[0124] It is preferably provided that the direct connection 910 runs through the interior of the handlebar 14, particularly preferably runs completely inside the handlebar 14.

[0125] Another possibility is that there is an indirect connection 920 from one of the two lighting devices 110, 120, for example the first lighting device 110, to an additional module 950 ( Fig. 10). Via such an indirect connection 920, additional functionality can be provided, in particular, by means of the additional module 950. This additional functionality can be provided, in particular, via the indirect connection 920 for the first lighting device 110 and optionally also for the second lighting device 120 via a possibly existing direct connection 910. Additional functionality for the first and / or second lighting device 110, 120 can consist in the first and / or second lighting device 110, 120 being supplied with energy via an external energy storage device 770 of the additional module 950 or, if the first and / or second lighting device 110, 120 comprises an internal energy storage device, this can be supplemented by the external energy storage device 770 of the additional module 950.It is also possible for the additional module to comprise an external charging unit for connecting a charging device, so that the first and / or second lighting device can be charged via the external charging unit. An external switching unit can also be attached to the additional module 950, so that the first and / or second lighting device can be switched via the external switching unit.

[0126] A further possibility is that between the two lighting devices 110, 120 there is an indirect connection 920, 922 to an additional module 950 ( Fig. 11). In this case, too, additional functionality can be provided for the first and / or second lighting device 110, 120 via the additional module. Furthermore, the two lighting devices 110, 120 can be indirectly connected to one another via the two indirect connections 920, 922 and the additional module 950, so that, for example, a charging unit on the first lighting device 110 can also charge the second lighting device 120 and / or a switching unit on the second lighting device 120 can also switch the first lighting device 110.

[0127] Preferably, an indirect connection 920, 922 is provided that it runs through the interior of the handlebar 14, particularly preferably inside the handlebar 14, and from there into the interior of the stem 12. From there, the indirect connection 920, 922 can extend outward. From the outside, the indirect connection 920, 922 can extend into the interior of the frame 2, in particular via the head tube 4 of the frame.

[0128] Another possibility is that an indirect connection 924 branches off from a direct connection 910 between the two lighting devices 110, 120 and runs to an additional module 950 ( Fig. 12). In this case, too, a mutual functional supplementation of the two lighting devices 110, 120 and / or a further provision of functionality via the additional module can take place, whereby the above statements apply analogously in particular.

[0129] Preferably, such an indirect connection 924 branches off from the direct connection 910 inside the handlebar 14 and extends into the interior of the stem 12. From there, the indirect connection 924 can extend outward. From the outside, the indirect connection 924 can extend into the interior of the frame 2, in particular via the head tube 4 of the frame.

[0130] Fig. 14 again shows an example of a direct connection 910 between two lighting devices 110, 120 mounted on the left and right sides of the handlebar. The direct connection 910 is designed as a ribbon cable that runs through the interior of the handlebar, so that it is not visible from the outside. The ribbon cable has two cable ends, one cable end being connected to the inner section 200 of the first lighting device 110, which is inserted into the interior of the handlebar 14, and the other cable end being connected to the inner section 200 of the second lighting device 120, which is inserted into the interior of the handlebar 14. A cable of a direct connection 910 can have a certain excess length, so that the first and / or second lighting device 110, 120 can be removed from the handlebar 14 while the cable is connected.

[0131] Fig. 15-16 show yet another example of a two-wheeled vehicle 1 with mounted first and second lighting devices 110, 120, as well as a direct connection 910 between the lighting devices 110, 120 and an indirect connection 920 to an additional module 950. This example is in some aspects similar to the Fig. 10 and Fig. 13 comparable.

[0132] In the example shown here, however, the handlebar unit 10 comprises a handlebar bracket 14 and a stem 12 integrally connected thereto, with the interior of the handlebar bracket 14 and the interior of the stem 12 communicating with each other, forming a shared interior space. Connections can run through this shared interior space, here the direct connection 910 and the indirect connection 920.

[0133] Fig. 17-18 show yet another example of a two-wheeled vehicle 1 with mounted first and second lighting devices 110, 120, as well as a direct connection 910 between the lighting devices 110, 120 and an indirect connection 920 to an additional module 950. This example is again similar in some aspects to the Fig. 10 and Fig. 13. In the example shown here, the handlebar unit 10 is, as in most previous examples, constructed in two parts and comprises a handlebar bracket 14 and a stem 12 clamped thereto, wherein an opening facing the interior of the stem 12 is provided in the center of the handlebar bracket 14, so that the interior of the handlebar bracket 14 communicates with the interior of the stem 12 and an indirect connection can run there.

[0134] The example shows that an indirect connection, here the connection 920, can optionally also run through the interior of the front wheel fork 6, in particular its fork shaft. This ensures that the connection does not emerge from the interior of the stem 12 to the outside, in order to then, for example, via the head tube 4, reach the interior of the frame 2. Rather, the front wheel fork 6 connected to the stem 12 has an opening at its upper end facing the interior of the stem 12, so that the interior of the front wheel fork 6 communicates with the interior of the stem 12, so that an indirect connection can run from the interior of the stem 12 into the interior of the front wheel fork 6. The front wheel fork also preferably has a further opening facing the interior of the frame 2, so that an indirect connection can reach from the interior of the front wheel fork into the interior of the frame.

[0135] Fig. 19-20 shows a lighting system mounted on a handlebar 14 of a two-wheeled vehicle 1, comprising lighting devices 110, 120, as well as a direct connection 910 between the lighting devices, an indirect connection 920 between the first lighting device 110 and an additional module 950, and / or an indirect connection 922 between the second lighting device 120 and the additional module 950. In this case, the indirect connection 920 and / or the indirect connection 922 runs externally on the handlebar 14. The direct connection runs through the interior of the handlebar 14. However, it is also possible in principle for a direct connection 910 to run externally on the handlebar 14.

[0136] Fig. 21 shows in more detail how a connection running externally on the handlebar 14, here the indirect connection 920, can be connected to a lighting device mounted on the handlebar 14, here the first lighting device 110. The connection running externally on the handlebar 14, here the indirect connection 920, can run between the handlebar 14 and the handlebar grip 20 fastened thereon up to the front end of the handlebar 14 and / or up to the outer section 300 of the lighting device. There, the connection running externally on the handlebar can be connected to the lighting device. It is possible for a connection running externally on the handlebar to be designed entirely or partially as a ribbon cable. In the case shown, for example, the part of the connecting cable running below the handlebar grip 20 is designed as a ribbon cable.

[0137] Fig. 22-24 show a first lighting device 110, which according to an embodiment of the invention can be functionally connected to a second lighting device 120, in particular via a means for connection 900.

[0138] The details explained below by way of example with reference to the first lighting device 110 are, unless exceptionally stated otherwise, equally valid for a second lighting device 120. Furthermore, the details explained below are also valid for lighting devices 110, 120 that can be operated independently of one another according to an embodiment of the invention, unless exceptionally stated otherwise.

[0139] The lighting device 110 comprises an inner section 200 with an inner section diameter 202 and an inner section length 204, and an outer section 300 with an outer section diameter 302 and an outer section length 304. The inner section length 204 is greater than the outer section length 304, preferably by at least a factor of 2, particularly preferably by at least a factor of 4. The outer section diameter 302 is greater than the inner section diameter 202, preferably by at least a factor of 1.25, particularly preferably by at least a factor of 1.5. Between the inner section 200 and the outer section 300, a transition is formed by a radial collar 400, which, when the lighting device 110 is mounted on the handlebar bracket 14, comes to rest against the front end of the handlebar bracket 14.

[0140] The inner section 200 of the lighting device 110 can have a contact terminal 850 for the detachable connection of a connecting means 900. Furthermore, the inner section 200 can accommodate an energy storage device, here the first energy storage device 750. In the assembled state, the energy storage device is thus located inside the handlebar 14. The energy storage device 750 can be located between the contact terminal 850 and the outer section 300 of the lighting device 110.

[0141] The outer section 300 of the lighting device 110 in particular has one or more lighting means 600. The outer section 300 preferably has a front light 610, which generates a front light beam 130 in the mounted state. The outer section 300 preferably also has a rear light 620, which generates a rear light beam 140 in the mounted state. It is possible for the outer section 300 to further have a floor light 630, which generates a floor light beam 150 in the mounted state.

[0142] Fig. 25-26 show how the lighting device 110 can be mounted on a handlebar grip 20 and / or on a handlebar 14. The lighting device 110 comprises mounting means 500, namely a fastening ring 510, fastening screws 520, and screw holes 410 located in the radial collar 400 of the lighting device 110.

[0143] The fastening ring 510 for the lighting device 110 is preferably designed as a handlebar grip fastening ring, so that the handlebar grip is fastened to the handlebar bracket 14 on the inner side with a handlebar grip fastening ring 22 and on the outer side with the fastening ring 510 for the lighting device 110. The fastening ring 510 is clamped to the handlebar bracket 14 and / or to the handlebar grip 20 using a device for circumferential variation 514. The fastening ring 510 is preferably fastened to the handlebar bracket 14 at the edge such that the fastening ring 510 forms a frontal contact surface on the front end of the handlebar bracket 14. When the lighting device 110 is mounted on the handlebar 14 and / or on the handlebar grip 20, the lighting device 110 thus comes to rest with its radial collar 400 on the fastening ring 510.

[0144] The fastening ring 510 has axial screw holes 512 which can be aligned with the screw holes 410 in the radial collar 410 of the lighting device 110 so that the lighting device 110 can be screwed to the fastening ring 510 with fastening screws 520.

[0145] The lighting device 110 is preferably constructed with multiple housing parts, in particular with an inner housing 250 and an outer housing 350 and, if appropriate, a sealing ring 480 located therebetween. The inner housing preferably comprises the radial collar 400 with the screw holes 410 for fastening. Preferably, the inner housing 250 can be simultaneously connected to the outer housing 350 by means of the fastening screws 520. However, it is also possible for the inner housing 250 to be connected to the outer housing 350 in another way.

[0146] Fig. 27 and Fig. 28 show further details of the structural design of the lighting device 110, which, as described, has in particular an inner housing 250 and an outer housing 350.

[0147] The inner housing 250 of the lighting device 110 has, in particular, an inner housing sleeve 260 in which an energy storage device of the lighting device 110 can be arranged. The inner housing sleeve 260 terminates on the side facing the outer housing 350 with an inner housing flange 270, which, on the one hand, forms the radial collar 400 and, on the other hand, serves for attaching a printed circuit board 430.

[0148] The outer housing 350 of the lighting device 110 has an outer housing end face 380 with a charging connection recess 382 located therein, so that a charging unit 700 is accessible from the end face and, for example, a charging plug can be plugged in. The charging connection recess 382 can be closed with a cover cap 390, wherein the cover cap 390 can be connected to the outer housing 350 in a particularly watertight manner, e.g., with the aid of a cover cap sealing ring 388.

[0149] As already explained, the details explained using the example of this lighting device 110 also apply to lighting devices that can be operated independently. Conversely, however, details that are described in connection with a lighting device that can be operated independently can also be applied to the lighting device 110 explained here, for example, the cover cap 390 can also be designed as in Fig. 7-8.

[0150] Between the inner housing 250 and the outer housing 350 is an intermediate housing 450, which is in particular made in one piece from a transparent material. This transparent intermediate housing 450 forms in particular lamp covers 656, 666, 676 for the lamps 610, 620, 630 of the lighting device 110. These lamp covers 656, 666, 676 engage in lamp recesses 370 in the outer housing shell 360 of the outer housing 350. The intermediate housing 450 also covers the components on the circuit board 430, but in the case of the first lighting device 110, has an axial charging port opening 452, which is accessible through the charging port recess 382 in the outer housing 350. The outer housing 350 is placed on the inner housing flange 270, with a sealing ring 480 preferably ensuring a watertight connection.

[0151] Fig. 29-30 show the circuit board 430 mounted on the inner housing flange 270 with components attached thereto. The lighting device 110 comprises a plurality of light sources 650, 660, 670, each with an associated light shaper 654, 664, 676. The light sources 650, 660, 670 are contacted on the same circuit board 430, as are the associated light shapers 654, 664, 676.

[0152] The first light source 650 and the first light shaper 654, and preferably the first light cover 656, form the front light 610 of the lighting device 110 and are configured to generate the front light beam 130. The first light source 650 is designed as a light-emitting diode arranged planarly on the circuit board 430 with an axial radiation direction, which is deflected into a radial radiation direction by the light shaper 654 designed as a reflector.

[0153] The second light source 660 and the second light shaper 664, and preferably the second lamp cover 666, form the rear light 620 of the lighting device 110 and are configured to generate the rear light beam 140.

[0154] The second light source 660 is also designed as a light-emitting diode arranged planarly on the circuit board 430 with an axial emission direction, which is deflected into a radial emission direction by the light shaper 664 designed as a reflector.

[0155] The third light source 670 and the third light shaper 674, and preferably the third light cover 676, form the floor light 630 of the lighting device 110 and are configured to generate the floor light beam 150. The third light source 660 is configured as a laser diode contacted on the circuit board 430 with radially focused radiation, which is fanned out into a linear radiation by the light shaper 674 configured as a line shaper. To ensure that the linear light beam runs along the longitudinal direction of the two-wheeled vehicle 1 in the mounted state, the light shaper is mounted rotated about the radial axis at a correction angle φ. This compensates for the oblique course of the handlebar 14 relative to the transverse direction of the two-wheeled vehicle 1.

[0156] Fig. 31-32 again show the first lighting device 110 of a lighting system 100 with two lighting devices 110, 120, which functionally complement each other. The first lighting device 110 has, in particular, a charging port 710, which is contacted on the circuit board 430 and is protected by the cover cap 390 that can be removed from the outer housing 350. For example, USB-PD can be provided for the charging port 710.

[0157] The charging port 710 of the first lighting device 110 can be used to charge both the energy storage device 750 of the first lighting device 110 and the energy storage device 760 of the second lighting device 120. In other words, the charging port 710 of the first lighting device 110 functionally complements the second lighting device 120, so that the latter preferably does not require its own charging port.

[0158] Fig. 33-35 show the second lighting device 120 of a lighting system 100 with two lighting devices 110, 120, which functionally complement each other. The second lighting device 120, like the first lighting device 110, has a contact terminal 850 arranged on the inner section 200, to which a connection means 900 can be connected in order to establish a direct connection to the first lighting device 110 and / or an indirect connection to an additional module 950. As already described, the above statements generally apply analogously to the second lighting device 120, unless otherwise stated.

[0159] Unlike the first lighting device 110, however, the second lighting device 120 in this example does not have its own charging port 710, a charging port recess 382 in its outer housing 350, or a cover cap 390. This is because the second energy storage device 760 is charged via the connection 900 in this case.

[0160] However, the second lighting device 120 comprises a switching unit 800 with a switch 810 contacted on the circuit board 430. The switch can be actuated via an actuating element 820, wherein the actuating element 820 in this example is composed of two elements. An elastically deformable disc 820, which can be pressed by a user, can be arranged in an actuating element recess 384 in the outer housing 350 (see Fig. 35). This allows a pressure pulse to be transmitted to the switch 810 via a further actuating element 820.

[0161] With the switching unit 800 of the second lighting device 120, both the lights 610, 620, 630 of the second lighting device 120 and the lights 610, 620, 630 of the first lighting device 110 can be switched. In other words, the switching unit 800 of the second lighting device 120 functionally complements the first lighting device 110, so that the latter preferably does not require its own switching unit.

[0162] Fig.36 shows a lighting device 110 of a lighting system 100 that can be mounted on a handlebar 14 and has an internal switch 830. The lighting device 110 that can be mounted on the handlebar preferably comprises a handlebar grip 20, wherein the handlebar grip 20 can be fastened to the handlebar, for example, with one or more handlebar grip fastening rings. In the example shown, the handlebar grip 20 can be fastened with an internal handlebar grip fastening ring 22 and with an edge fastening ring 510, which can also serve to fasten the lighting device 110.

[0163] In this example, the lighting system 100 comprises a switching unit 800 with an internal switch 830, designed in particular as a push-button, which, when the lighting device is mounted, is directed rearward with respect to the two-wheeled vehicle and can be actuated in the radial direction, in particular by a pressure pulse. In this example, the internal switch is arranged in the handlebar grip 20, in particular on the side facing the internal handlebar grip fastening ring 22. It is therefore particularly possible to actuate the internal switch 830 with the thumb. The internal switch 830 can, for example, be designed to actuate a turn signal mode, so that one or more of the lights of the lighting means 600 can serve as direction indicators.

[0164] Of course, the lighting system 100 can have an internal switch 830 on each side of the handlebar. These internal switches 830 can be arranged in the respective lighting device 110, 120, in particular in a handlebar grip 20 associated therewith and / or an associated fastening body.
