Description

Technical Field

[0004]

[0001] The present invention relates to a lighting system for a two-wheeled vehicle, particularly a bicycle or an electric bicycle, comprising a frame having a head tube, and a front fork rotatably supported within the head tube and connected via a stem to a tubular handlebar.

Background Art

[0002] Lighting devices are an important equipment for bicycles or electric bicycles (e-bikes), especially when the light conditions are poor or in dark places. Lighting results in the bicycle and the bicycle rider being well visible to other road users, and thus contributes decisively to safety in road traffic.

[0003] For bicycles or e-bikes that do not have lights pre-mounted, there is an opportunity to add lighting equipment. In this case, usually, front lighting and / or rear lighting is used, and the front lighting is often mounted at the handlebar or the front part of the frame or fork, and the rear lighting is often mounted at the saddle or the rear part of the frame, respectively.

[0004] Modern lighting devices are usually driven by a battery or a rechargeable battery, which is either removably accommodated in a battery compartment in the front lighting or rear lighting, respectively, or, in the case of a rechargeable unit, can be firmly incorporated.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Against this backdrop, the fundamental problem of the present invention is to improve and / or further develop existing lighting solutions in several respects by providing a lighting system that can be added to or firmly mounted on two-wheeled vehicles, particularly bicycles or e-bikes, and is optimized in particular with respect to fixing and / or integration with two-wheeled vehicles, with respect to lighting and visibility for other road users and therefore traffic safety, in the case with respect to the design and coordination of multiple lighting devices with respect to user-friendliness when switching on or off and / or charging, and / or with respect to appearance when installed. [Means for solving the problem]

[0006] To address this problem, the present invention discloses a lighting system for two-wheeled vehicles, particularly bicycles or electric bicycles, comprising a frame having a head tube, and a front fork rotatably supported within the head tube and connected to a tubular handlebar via a stem.

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

[0008] The first lighting device has an inner section and an outer section connected to the inner section. The inner section is insertable axially into the interior of the tubular handlebar at the first end face of the tubular handlebar. The outer section protrudes axially beyond the first end face of the tubular handlebar when the first lighting device is in operation, particularly when the inner section is inserted axially into the interior of the tubular handlebar at the end face of the tubular handlebar.

[0009] Preferably, the lighting system further includes a second lighting device for mounting to a second end face of a tubular handlebar.

[0010] In that case, the second lighting device may preferably be identical to the first lighting device in some respects. In principle, the features generally described below for lighting devices are applicable to the first and / or second lighting devices, insofar as the second lighting device is included and unless otherwise specified.

[0011] If a second lighting device is included, the second lighting device also has an inner section and an outer section connected to the inner section. The inner section is insertable axially into the interior of the tubular handlebar at the second end face of the tubular handlebar. The outer section protrudes axially beyond the second end face of the tubular handlebar when the second lighting device is in operation, particularly 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 inner and outer sections of the first and / or second lighting device are connected to each other, in particular. The connection of the inner section to the outer section may be carried out, for example, via a rigid material connection, for example, in a rigid and / or load-bearing manner. For example, the inner section may support the outer section and / or the outer section may be fixed to the inner section. Furthermore, for example, the connection of the inner section to the outer section may be formed via a single material connection. However, for example, the connection of the inner section to the outer section may also be carried out in a removable manner, for example, using a mechanical fastening system for removable mechanical fastening.

[0013] The first and / or second lighting devices may be adapted, in particular, for retrofitting and / or removable mounting to standard bicycle handlebars.

[0014] The first and / or second lighting devices may be adapted to be mounted on a tubular handlebar, for example, whose end faces project laterally outward, i.e., extending laterally with respect to the longitudinal direction defined by the two-wheeled vehicle, and / or projecting along a direction extending laterally with respect to a plane stretched by the longitudinal and vertical directions. Thus, the first and / or second lighting devices may be adapted to be mounted on the handlebars of a mountain bike in particular. The lighting system according to the present invention is intended in particular for two-wheeled vehicles including handlebars and / or pedals, in particular for two-wheeled vehicles that can be driven solely by muscle power or with the supplementation of muscle power, i.e., bicycles that may optionally include an electric motor (so-called e-bikes or pederecs). Thus, the frame of the two-wheeled vehicle, i.e., the support structure, includes in particular a bottom bracket sleeve for housing a bottom bracket for a crankset having pedals. The frame of the two-wheeled vehicle further includes, in particular, a down tube connected on the one hand to a head tube and on the other hand to a bottom bracket sleeve. Furthermore, the frame of a two-wheeled vehicle includes, in particular, a saddle tube provided for housing the saddle.

[0015] In the installed state, the inner sections of the first and / or second lighting devices are inserted into the interior of the tubular handlebar. The inner sections are, in particular, completely inserted into the handlebar, and as a result, the entire inner section is surrounded radially by the tubular handlebar. In the installed state, the outer sections may preferably protrude axially beyond the end faces of the tubular handlebar. In particular, when the lighting devices are in operation, the outer sections protrude axially beyond the end faces of the tubular handlebar.

[0016] The inner and outer sections of the first and / or second illuminating device define, in particular, the shape of the illuminating device as viewed radially.

[0017] Therefore, the inner sections of the first and / or second lighting devices have an inner section diameter smaller than that of a standard bicycle handlebar, particularly in the grip area. A standard bicycle handlebar can be understood as, in particular, a commercially available bicycle handlebar.

[0018] The outer sections of the first and / or second lighting devices may have an outer section diameter larger than the inner section diameter. Thus, the outer sections may protrude radially beyond the inner section and / or exceed the diameter of a standard bicycle handlebar in the grip area.

[0019] The first and / or second lighting device may further include a radial collar that forms a transition between the inner section and the outer section, and / or between the diameter of the inner section and the diameter of the outer section. Such a radial collar may be formed, for example, in a stepped manner in the axial cross-section. The radial collar may be formed to contact the end face of the tubular handlebar when the inner section is inserted into the interior of the tubular handlebar.

[0020] Therefore, viewed radially, the outer section diameter may be larger than the inner section diameter. However, the possibility that the outer section diameter and the inner section diameter are the same, or that the outer section diameter is smaller than the inner section diameter, is not ruled out in principle. However, as mentioned above, the outer section protrudes beyond the end face of the tubular handlebar when viewed axially, especially when the lighting device is installed and / or in operation.

[0021] Preferably, the first and / or second lighting device includes means for attaching to the end face of a tubular handlebar.

[0022] The attachment means may include one or more screw holes of a color in the radial direction of the lighting device. Such screw holes can, for example, extend through the radial color and into the outer section, so that for attaching the lighting device, a screw can be screwed into such a screw hole.

[0023] The attachment means may further include a fixing body that can be fixed, on the one hand, to a tubular handlebar and / or to a handlebar grip, and on the other hand, can be fixed directly or indirectly to the lighting device. Such a fixing body can in particular be formed as a fixing ring.

[0024] For example, the fixing body can be formed to be clampable to a tubular handlebar, and the lighting device can be formed to be screwable directly to the fixing body such that it can be fixed to the fixing body by one or more screws, and the lighting device preferably contacts the fixing body in the fixed state. However, indirect fixing is also possible. For example, the lighting device can be fixed to another element for the time being, and the said other element can be fixed to the fixing body.

[0025] The fixing body formed as or including a fixing ring can in particular be provided with a device for perimeter change in order to preferably clamp the fixing ring externally to a tubular handlebar.

[0026] The fixing body may have one or more screw holes extending axially through the fixing body so that it can be screwed together with the lighting device. For example, it can be contemplated that the fixing body can be screwed axially together with the screw holes of the radial color of the lighting device by means of these screw holes.

[0027] The fixing body or the fixing ring can preferably be formed as a standard clamping ring compatible with a standard bicycle handlebar grip system. A standard bicycle handlebar grip system should in particular be understood as a commercially available bicycle handle grip with an associated commercially available clamping ring.

[0028] It is also possible for the attachment means to include a device for fixing the lighting device inside to the handlebar. For example, it is possible for the inner section to be fixable from the inside within a tubular handlebar. For example, a fixing body may be included which on the one hand is fixable from the inside within a tubular handlebar and on the other hand is fixable to or is fixed to the inner section of the lighting device.

[0029] Regarding the dimensions of the first and / or second lighting devices, in particular, the following values may be contemplated. <​​​​​​​​​​​​​​​​​​​​​​​​​​Specifically, the lighting means of the first and / or second lighting device may include a forward light adapted to produce a forward beam, particularly a forward beam directed forward from the motorcycle when mounted. Such a forward beam may preferably have an aperture angle of 30 to 160 degrees.

[0037] The lighting means may further include a rear light adapted to generate a rear beam, particularly a rear beam directed backward from the motorcycle when mounted. Such a rear beam may preferably have an aperture angle of 15 to 80 degrees.

[0038] The front lights are designed to continuously illuminate the area in front, in particular to provide better visibility to the motorcyclist in low light conditions and / or to enhance the visibility of the motorcyclist for other road users. The rear lights are designed to continuously or continuously flash or pulsate to illuminate the area behind, in particular to enhance the visibility of the motorcyclist for other road users. However, it is not excluded that the front lights and / or rear lights have other functions, such as temporary functions as turn signals.

[0039] The front light of the illumination means of the first and / or second illumination device preferably has a radial direction extending laterally with respect to the axial direction, along which an inner section can be inserted into the interior of a tubular handlebar. The rear light of the illumination means of the first and / or second illumination device also preferably has a radial direction extending laterally with respect to the axial direction, along which an inner section can be inserted into the interior of a tubular handlebar. The front light and / or rear light have a radial direction extending laterally from the outer housing, i.e., laterally with respect to the normal of the end face of the outer housing. Thus, the illumination device is particularly suitable for handlebars whose end faces project laterally outward, i.e., particularly mountain bike handlebars.

[0040] Within the framework of this explanation, the direction of radiation should be understood as the direction of radiation from the center of the light cone.

[0041] The front light of the first lighting device is adapted to produce a first forward luminous flux that, together with a second forward luminous flux of a second lighting device which is particularly preferably included, in order to provide the rider of the motorcycle with a better field of view in dark places, forms an overall forward luminous flux particularly suitable for continuous illumination forward.

[0042] In other words, the first forward luminous flux of the first lighting device is preferably matched to the second forward luminous flux of the second lighting device, which is preferably included. The second forward luminous flux of the second lighting device, which is preferably included, is also preferably matched to the first forward luminous flux of the first lighting device.

[0043] The first forward luminous flux of the first lighting device is preferably designed such that there exists a first maximum luminous intensity surrounded by lower luminous intensities along at least one first principal radiation direction, where only the first forward luminous flux is considered. The first forward luminous flux is preferably further designed such that the first maximum luminous intensity is offset laterally with respect to the plane of the motorcycle. In other words, the first maximum luminous intensity is located, for example, to the right of the plane of the motorcycle, i.e., the plane spanned by the longitudinal and vertical directions of the motorcycle, when the first lighting device is mounted and / or in operation.

[0044] Preferably, the second forward luminous flux of the second lighting device is designed such that there exists a second maximum luminous intensity surrounded by lower luminous intensities along at least one second principal radiation direction, where again only the second forward luminous flux is considered. Preferably, the second forward luminous flux is further designed such that the second maximum luminous intensity is offset laterally with respect to the plane of the motorcycle. In other words, when the second lighting device is installed and / or in operation, the second maximum luminous intensity is located, for example, to the left of the plane of the motorcycle, i.e., the plane spanned by the longitudinal and vertical directions of the motorcycle.

[0045] The total forward luminous flux is preferably designed such that at the central position, there exists a total luminous intensity that is at least 10% of the first maximum luminous intensity and / or at least 10% of the second maximum luminous intensity. Preferably, the aforementioned values ​​may be higher than 10%, particularly 25%, particularly 50%, particularly 75%, particularly 100%, particularly 125%, or particularly 150%.

[0046] In that case, the central position should be understood as a position within the entire forward luminous flux that lies within the plane of the motorcycle, i.e., the plane spanned by the longitudinal and vertical directions of the motorcycle. Furthermore, the central position is preferably within the plane of the ground. In other words, the central position is preferably on the line formed by the intersection of the plane of the motorcycle and the plane of the ground. Furthermore, the central position is preferably within the plane spanned by the first principal radiation direction of the first maximum luminous intensity and the second principal radiation direction of the second maximum luminous intensity. In other words, the central position is preferably on the line formed by the intersection of the last mentioned plane with the plane of the motorcycle or the plane of the ground, or on the point formed by the intersection of the three aforementioned planes.

[0047] At the central position, the luminosities of the two forward beams, namely the lower luminosities surrounding the first maximum luminosity and the lower luminosities surrounding the second maximum luminosity, overlap.

[0048] As described above, the front lights of the first and / or second lighting devices preferably have a radial direction extending laterally with respect to the axial insertion direction into the tubular handlebar. The radial direction of the first and / or second lighting devices is further preferably directed inward. In particular, the radial direction of the first and / or second lighting devices has an angle greater than 90 degrees, preferably greater than 93 degrees, preferably greater than 96 degrees, and preferably greater than 100 degrees with respect to the axial normal pointing outward, i.e., the normal to the outer housing end face, for example. This takes into account situations in which the tubular handlebar extends obliquely with respect to the lateral direction of the motorcycle.

[0049] The radiation direction of the first and / or second lighting device is further preferably directed downward or can be directed downward. This is particularly the case where the radiation direction of the first and / or second lighting device has an angle greater than 90 degrees, preferably greater than 100 degrees, and preferably greater than 110 degrees, with respect to the upward direction vector.

[0050] The lighting means may further include ground lights adapted to generate ground luminous flux, particularly ground luminous flux directed downward from the motorcycle when mounted. Such ground luminous flux may preferably have a longitudinal aperture angle of 20 to 130 degrees and / or a lateral aperture angle of less than 30 degrees.

[0051] In this case, the longitudinal opening angle should be understood in particular as the longitudinal opening angle, that is, the opening angle in the direction extending from rear to front with respect to the motorcycle when each lighting device is mounted on the motorcycle. The lateral opening angle should be understood accordingly, in particular as the lateral opening angle, that is, the opening angle in the direction extending from left to right with respect to the motorcycle, particularly perpendicular to the longitudinal direction, when each lighting device is mounted on the motorcycle.

[0052] The lighting means of the first and / or second lighting device are preferably located in the portion of the lighting device that protrudes axially beyond the end face of the tubular handlebar when mounted and / or operating, i.e., particularly in the outer section.

[0053] The first and / or second lighting device comprises various housing components, as will be described in more detail below.

[0054] Preferably, the first and / or second lighting device includes an inner housing comprising an inner housing sleeve and an inner housing flange optionally connected thereto. In this case, the inner housing sleeve particularly forms the inner section of the lighting device.

[0055] An inner housing, which can be inserted into the interior of at least a partially tubular handlebar, is preferably connected to an outer housing that protrudes outward when installed.

[0056] The first and / or second lighting device includes, in particular, an outer housing having an outer casing having one or more light recesses and an outer casing end face. In this case, the outer housing and optionally an inner housing flange preferably form the outer section of the lighting device.

[0057] The illumination means described above may include, in particular, one or more light sources, each having an optionally assigned light shaper, which are preferably mounted on a circuit board located on an inner housing flange. The one or more light sources, each having an optionally assigned light shaper, in particular form one or more lights of the illumination means.

[0058] Furthermore, the first and / or second lighting devices may be positioned between the inner and outer housings and may include a particularly integrated intermediate housing that is transparent.

[0059] Such intermediate housings may form one or more light covers that enclose one or more light sources, each having an optionally assigned light shaper, and preferably engage with one or more light recesses in the outer casing. Such covers for the light sources and optionally assigned light shapers are preferably designed to be waterproof so that the light sources and optionally light shapers are protected from moisture.

[0060] The first and / or second lighting device may, in particular, include a sealing ring positioned between the inner housing and the outer housing and / or intermediate housing.

[0061] Furthermore, a seal against water intrusion may be provided between the intermediate housing and the outer housing. For this purpose, for example, a sealant can be introduced into the gap between the intermediate housing and the outer housing, and the sealant can, for example, completely fill the gap.

[0062] The inner and outer housings of the first and / or second lighting devices are preferably connected to each other. The connection of the inner housing to the outer housing can be carried out, for example, via a rigid material connection, for example, in a rigid and / or load-bearing manner. For example, the inner housing can support the outer housing and / or the outer housing can be fixed to the inner housing. Furthermore, for example, the connection of the inner housing to the outer housing can be carried out in a removable manner, for example, using a mechanical fastening system for removable mechanical fastening. Regarding materials, for example, the inner housings of the first and / or second lighting devices may be intended to include or consist of, for example, plastic. However, the inner housings may also include or consist of, for example, metal. The transparent intermediate housing may include or consist of, for example, plastic. The outer housing may include or consist of, for example, metal. However, the outer housings may also include or consist of, for example, plastic. Preferably, the outer casing is intended to include or consist of a material that is harder than the material of the intermediate casing. One advantage of this is that the outer housing can mechanically protect the intermediate housing, especially if the outer housing protrudes axially at one handlebar end and is therefore subject to mechanical loads, such as impacts.

[0063] In the following, we will refer in more detail to several different lights of the lighting device, each assigned to a light source and / or light shaper.

[0064] Lights, i.e., front lights and / or rear lights, may each include, in particular, a light source and an assigned light shaper. The light shaper can affect the direction of radiation and / or the aperture angle, so that the radiation angle and / or aperture angle of the light differs from the radiation angle and / or aperture angle of the light source.

[0065] For example, the first light source of the front light has an axial radiation direction and can be deflected laterally with respect to the axial direction by an assigned first light shaper. For example, the second light source of the rear light also has an axial radiation direction and can be deflected laterally with respect to the axial direction by an assigned second light shaper. This makes it possible for the lighting device to be particularly suitable for handlebars, especially those with end faces that protrude laterally outward, i.e., mountain bike handlebars. At the same time, a flat structure is possible by the fact that the first and / or second light sources can be mounted flat in a plane defined, for example, by a normal vector along the axial direction.

[0066] In particular, it may include a first light source having an assigned first light shaper that forms a forward light, the first light source being designed as a light-emitting diode having an axial radiation direction, and the light shaper being designed as a reflector that deflects the axial radiation direction to a radial radiation direction.

[0067] In other words, the first light source has a radiation direction perpendicular to the surface of the circuit board, and the assigned reflector can be mounted on the circuit board such that it causes a deflection in a radiation direction parallel to the surface of the circuit board.

[0068] Furthermore, a second light source having an assigned second light shaper to form a rear light may be included, the second light source being designed as a light-emitting diode having an axial radiation direction, and the light shaper being designed as a reflector that deflects the axial radiation direction to a radial radiation direction.

[0069] Here again, the second light source has a radiation direction perpendicular to the surface of the circuit board, and the assigned reflector may be mounted on the circuit board such that it causes a deflection in a radiation direction parallel to the surface of the circuit board.

[0070] Furthermore, it may include a third light source having an assigned third light shaper, which forms a ground light, the third light source being designed as a laser diode having radially bundled radiation, and the light shaper being designed as a linear shaper that emits radially bundled radiation in the longitudinal direction.

[0071] In other words, the laser diode can be mounted on a circuit board such that the radiation is substantially point-like along a direction parallel to the surface of the circuit board. As a result, the linear shaper can spread the essentially point-like radiation in one dimension into a fan shape, resulting in substantially linear radiation. This allows, for example, the laser beam to be projected onto the ground.

[0072] The linear shaper described above is preferably rotated by a correction angle around the radial direction such that the longitudinal direction of the fan-out extends obliquely with respect to a plane perpendicular to the axial direction by a correction angle. The correction angle is preferably 3 to 15 degrees.

[0073] Therefore, the correction angle may take into account situations where, in particular, a tubular handlebar extends diagonally to the lateral direction of the motorcycle.

[0074] The front lights and / or rear lights may each include a light source and an assigned light shaper, as described above. The light source and the light shaper are preferably designed as separate components. This has the advantage that, for example, a standard LED can be used as the light source, and a special light shaper adapted to this lighting device can be used as the light shaper.

[0075] An optical shaper may include, for example, a lens, or may be designed as a lens. An optical shaper may also include, for example, a reflector, or may be designed as a reflector. An optical shaper designed as a reflector may, in particular, have a reflective surface, preferably a reflective coating which may be vapor-deposited, and include a substrate made of, for example, plastic.

[0076] The light shaper for the front light of the first and / or second lighting device is preferably designed to deflect the primary radiation direction of the first light source where the first maximum luminous intensity exists to the primary radiation direction of the first forward luminous flux as described above. This is because the primary radiation direction of the light source assigned to the front light (the first light source) is preferably different from the desired primary radiation direction of the front light (including the light shaper) by an angle of at least 3 degrees, at least 90 degrees, and at least 93 degrees. The primary radiation direction of the first light source may extend, for example, along the axial insertion direction.

[0077] The front lights of the lighting system are specifically designed as headlights, and the light from the light source is deflected and focused by a light shaper.

[0078] The light shapers for the rear lights of the first and / or second lighting devices may also be designed to deflect the radiation direction of the light source (second light source) assigned to the rear light. The rear light shapers may include or be designed as light guides. The rear light source and light shapers may also be designed as an integrated component.

[0079] In many embodiments, the lighting system, in particular the first and / or second lighting device, includes a charging unit.

[0080] The charging unit may preferably include a charging connection portion for connecting a charging device, the charging connection portion preferably contacts a circuit board located on the inner housing flange of the inner housing.

[0081] Optionally, the outer housing may further have a charging connection recess for a charging connection, and the charging connection recess may preferably be located on the end face of the outer housing.

[0082] Optionally, an intermediate housing positioned between the inner housing and the outer housing may be intended to have a charging connection opening for a charging connection, wherein the charging connection opening preferably extends axially through the intermediate housing.

[0083] The first and / or second lighting device may further optionally include a cover cap that covers a recess for a charging connection within the outer housing.

[0084] Such cover caps may preferably include a flexible retaining web held in the outer housing and / or intermediate housing.

[0085] In an advanced form, the charging unit may optionally include a coil for inductive charging and / or a magnet for mounting the charging device. For example, the charging device may be magnetically fixed to the outer casing end face in the axial direction to generate inductive coupling with the coil for inductive charging.

[0086] The charging unit further includes, in particular, a charge controller, or is connected to a charge controller of a lighting system, or a charge controller located within a lighting system. Such a charge controller includes, in particular, circuitry for controlling the charging of a rechargeable energy storage device, such as a lithium-ion battery or a lithium-polymer battery. The charge controller may be designed, for example, as a microchip located within a lighting system, or integrated into such a microchip. The charge controller may include, in particular, a charge management system adapted to set, select from various options, and / or adapt during charging, the charging current and / or the charging voltage for charging the energy storage device. The charge controller may include, in particular, a charge termination function adapted to determine whether the energy storage device is sufficiently charged and / or to terminate the charging process. The charge controller may also be adapted to limit the charging current based on temperature measurement, for example. The charge controller may be designed, for example, as a linear charge management controller within an integrated circuit.

[0087] The charging unit may further be adapted to control a charging indicator that indicates, in particular, that the charging process is taking place while charging is in progress, and / or that the charging process is complete after charging is finished.

[0088] In many embodiments, lighting systems, in particular first and / or second lighting devices, include switching units for switching lighting means, in particular the lights of the lighting means. Such switching units may be adapted in particular to turn the lighting means, in particular the lights of the lighting means, on or off or switch between different operating modes.

[0089] The switching unit preferably includes a switch, particularly designed as a push button, which is in contact with a circuit board, preferably located on the inner housing flange of the inner housing. Within the framework of this application, the term “switch” should be understood as a broader concept of a component that can open or close a circuit by user intervention.

[0090] The switching unit may preferably include an actuation element connected to a switch and operable by a user to switch the switch. Such an actuation element may, in particular, be mechanically connected to or in contact with the switch to switch the switch. Furthermore, such an actuation element may be designed to consist of multiple parts, one or more actuation element parts of which may be mechanically connected to or in contact with each other to transmit actuation impulses to the switch.

[0091] Optionally, the outer housing may have a recess for the actuation element, and optionally, the intermediate housing positioned between the inner and outer housings may have an opening for the actuation element.

[0092] The switching unit may be designed as a shell-side switching unit, in particular, such that the actuating element is located in the outer housing shell, the actuating element recess is preferably located within 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 applying pressure in the radial direction.

[0093] The switching unit may be designed as an end-face switching unit such that the actuation element is located on the end face of the outer housing, the actuation element recess is preferably on the end face of the outer housing, and the actuation element opening preferably extends axially through the intermediate housing. In this case, the actuation element can be actuated, in particular, by applying pressure in the axial direction.

[0094] The end-face switching unit may include, for example, an actuation element having an elastically deformable disk disposed on the end face, and optionally having a further actuation element portion disposed between the elastically deformable disk and the switch to transmit pressure impulses.

[0095] In the developmental form, the first and / or second lighting device may include a switching unit having a switch specifically designed as a push button, which, when the lighting device is installed, is oriented backward with respect to the motorcycle and is actuated in particular by radial pressure impulses. Such an internal switch may be intended as an alternative or additional component.

[0096] In principle, the switches of the switching unit, particularly the internal switches, can also be located within the mounting body, handlebar grip, and / or handlebar grip mounting ring.

[0097] Embodiments of the present invention, particularly characterized by independent first and second lighting devices, are described below.

[0098] According to one embodiment of the present invention, the first lighting device may include a first energy storage device adapted to operate the lighting means of the first lighting device.

[0107] Optionally, the first and / or second lighting device may include a contact connection for removable contacts of the connecting means, the contact connection preferably located in the inner section and / or inner housing of the first and / or second lighting device, particularly preferably at the axial end opposite to the outer housing.

[0108] Embodiments of the present invention, particularly characterized by first and second lighting devices that are functionally complementary to one another, are described below.

[0109] According to one embodiment of the present invention, the lighting system includes an energy storage system adapted to operate the lighting means of a first lighting device and the lighting means of a second lighting device.

[0110] The energy storage system includes one or more of the following energy storage devices: a first energy storage device located within a first lighting device, a second energy storage device located within a second lighting device, and / or an external energy storage device located outside the first and / or second lighting devices, for example, in an additional module that may be mounted on or within the frame of a motorcycle.

[0111] It is possible that at least one of the energy storage devices in an energy storage system is jointly adapted to operate the lighting means of a first lighting device and a second lighting device. However, it is also possible that a particular energy storage device in an energy storage system is adapted for the operation of a particular lighting device, for example, a first energy storage device located within a first lighting device for the operation of the lighting means of the first lighting device, and a second energy storage device located within a second lighting device for the operation of the lighting means of the second lighting device.

[0112] Furthermore, the lighting system may preferably include a switching unit, particularly as described above, configured to switch the lighting means of a first lighting device and the lighting means of a second lighting device by transmitting a switching signal via a connecting means.

[0113] Preferably, the energy storage device of the energy storage system is designed as a rechargeable energy storage device, the first lighting device has a charging unit, particularly as described above, for charging the rechargeable energy storage device by a charging current being transmitted through a connecting means, and the switching unit is designed, particularly as an end-face switching unit of the second lighting device.

[0114] In the following, several possibilities for how the means for connecting the first lighting device to the second lighting device may be configured will be described.

[0115] The connection means may include a direct connection portion extending from the first lighting device to the second lighting device.

[0116] However, the connection means may also include indirect connections extending from the first lighting device to, for example, an additional module mounted on or within the frame.

[0117] The connection means may also include indirect connections extending from the second lighting device to, for example, an additional module mounted on or within the frame.

[0118] The connection means may also include indirect connection sections extending from direct connection sections to additional modules.

[0119] If the connection means includes both a direct connection from the first lighting device to the second lighting device and an indirect connection from at least one lighting device, or a direct connection to an additional module, the connection of the lighting devices can be made directly and / or indirectly, and additional functionality may be provided via the additional module as needed.

[0120] If the connection means includes both an indirect connection from the first lighting device to the additional module and an indirect connection from the second lighting device to the additional module, the connection of the lighting devices may be made via the additional module, which can provide further functionality as needed.

[0121] Additional modules can optionally provide further functionality. For example, an additional module may provide space for an external energy storage device. However, it is also possible for the additional module to include an external charging unit and / or an external switching unit. Furthermore, the additional module can be designed as an energy storage device and / or control unit for an electric bicycle (e-bike), or may include such an energy storage device and / or such a control unit.

[0125] The indirect connection can, more preferably, extend through the inside of the stem. It is also possible for the indirect connection to extend partially outside the stem.

[0126] Preferably, the indirect connection portion may be intended to extend both through the inside of the tubular handlebar and the inside of the stem connected to the handlebar, particularly by extending directly from the inside of the tubular handlebar to the inside of the stem.

[0127] The indirect connection can further preferably extend through the interior of the frame, for example, through the head tube. It is also possible for the indirect connection to partially extend outside the frame. To reach the interior of the frame, the indirect connection can enter, for example, from the outside of the frame into the head tube of the frame.

[0128] As described above, the front fork is rotatably supported within the head tube of the frame. In this case, the steering tube of the front fork extends through the inside of the head tube. However, the steering tube of the front fork can have an outer diameter smaller than the inner diameter of the head tube, and as a result, a space remains inside the head tube but outside the steering tube of the front fork through which an indirect connection can extend.

[0129] However, optionally, the indirect connection can also extend through the inside of the front fork, particularly through the inside of the steering tube. Similarly, the indirect connection can extend partially outside the front fork.

[Modes for carrying out the invention]

[0168] Figures 1-3 show a two-wheeled vehicle 1, in this case a bicycle 1, on which a lighting system 100 having two lighting devices 110 and 120 is mounted in operation on its handlebars. The first lighting device 110 is on the right side of the handlebars, and the second lighting device 120 is on the left side of the handlebars.

[0169] The two lighting devices 110 and 120 can generate multiple luminous beams directed in various directions relative to the two-wheeled vehicle 1. One or more forward luminous beams 130 are directed forward relative to the bicycle 1. In the case shown herein, each of the two lighting devices 110 and 120 is adapted to generate such forward luminous beams 130. Furthermore, one or more rearward luminous beams 140 are directed rearward from the bicycle 1. Here again, each of the two lighting devices 110 and 120 is adapted to generate such rearward luminous beams 140.

[0170] In addition, the lighting devices 110 and 120 can also generate one or more ground luminous fluxes 150 formed linearly on the ground. Specifically, such linear ground luminous fluxes 150 can be radiated from the mounted lighting devices 110 and 120 so as to extend along the longitudinal direction of the motorcycle 1. In the case shown here, each of the two lighting devices 110 and 120 is adapted to generate such a front luminous flux 150.

[0171] Figure 4 shows a two-wheeled vehicle 1, again a bicycle 1, comprising a frame 2 including a head tube 4 and a front fork 6 rotatably supported within the head tube 4, the front fork 6 being connected to a tubular handlebar 14 via a stem 12, the handlebar 14 having handlebar grips 20 on each side.

[0172] According to embodiments of the present invention, the motorcycle 1 is fitted with two lighting devices 110, 120 that can operate independently of each other. The lighting devices 110, 120 may be, for example, two identical or mirror-symmetrical units. Each of the two lighting devices 110, 120 is attached to the end faces 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 the handlebar grip 20 at one of the two front ends 16, 18 of the handlebar 14, and the lighting devices 110, 120 are preferably only partially inserted so that they still partially protrude from the interior of the handlebar 14 and / or the handlebar grip 20, especially when in operation.

[0173] Figures 5-6 show in more detail the form and mounting of an example of a first lighting device 110, and a corresponding example is preferably applied to a second lighting device 120. The lighting device 110 has an inner section 200 and an outer section 300 connected to the inner section 200. The inner section 200 is insertable into the inside of the handlebar grip 20 and / or the inside of the handlebar 14, and the handlebar grip 20 is mounted on or can be mounted on the handlebar 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 14.

[0174] The outer section 300 includes one or more illuminating means 600 for generating one or more luminous beams. One of the illuminating means 600 is provided, for example, for generating a forward luminous beam 130. In addition, the outer section 300 of the lighting device 110 includes a switching unit 800 for turning one or more illuminating means 600 on, off, or switching between various operating modes. The outer section 300 also includes a charging unit 700, to which a charging device may be connected for charging the lighting device 110.

[0175] In the illustrated example, the charging unit 700 is located on the end face of the outer section 300 and may be protected by a cover cap 390 that is also attached to and / or removable from the end face. Furthermore, in the illustrated example, the switching unit 800 is located on the outer periphery of the outer section 300. Of course, other arrangements of the charging unit 700 and / or the switching unit 800 are also possible.

[0176] Figures 7-8 show some further details of the first lighting device 110 mounted on the handlebars 14 and / or handlebar grips 20. In particular, it can be seen that mounting means 500 may be used to removably secure the lighting device 110 to the handlebars 14 and / or handlebar grips 20. Specifically in this example, it is a fixing ring 500 that can grip the handlebars 14 and / or handlebar grips 20 from the outside on the one hand, and thus be clamped, and on the other hand can be screwed onto the lighting device 110, for example, its outer housing 300.

[0177] The cover cap 390, as shown here, has a flexible retaining web 392, which holds the cover cap 390 within the opening of the outer housing 300 to prevent loss of the cover cap 390. Furthermore, the cover cap 390 is provided with a sealing lip 394 to allow for good retention and / or waterproof protection for the charging unit 700.

[0178] Figures 9-13 show a motorcycle 1 having a frame 2, a head tube 4, a front fork 6, a stem 12, and a handlebar 14. According to one embodiment of the present invention, the illustrated motorcycle 1 is fitted with two lighting devices 110, 120, which are directly and / or indirectly connected via connecting means 900, thereby functionally complementing each other. In particular, the connecting means 900 may enable the energy storage systems of the two lighting devices 110, 120 to be charged via the same charging unit, and / or the lighting means of the two lighting devices 110, 120 to be switched via the same switching unit.

[0179] The connection between the two lighting devices 110 and 120 can be realized in different ways. The lighting system may further include an additional module 950, which may enable an indirect connection between the two lighting devices 110 and 120 and / or provide further functionality. For example, the additional module 950 may have an external energy storage device 770. Several options for direct and / or, in some cases indirect connections involving the additional module 950 are described below, but these are illustrative and should not be understood as definitive.

[0180] One possibility is that a direct connection 910 exists between the first lighting device 110 and the second lighting device 120 (see Figure 9). Such a direct connection 910 can be made, for example, via a connecting cable, which has two cable ends, with the first cable end connected to the first lighting device 110 and the second cable end connected to the second lighting device 120. Such a direct connection may allow the charging unit of the first lighting device 110 to also charge the second lighting device 120, and / or the switching unit of the second lighting device 120 to also switch the first lighting device 110.

[0181] In this case, it is preferable that the direct connection portion 910 extends through the inside of the handlebar 14, and more preferably that it extends entirely inside the handlebar 14.

[0182] 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 the additional module 950 (Figure 10). In particular, further functionality may be provided by the additional module 950 via such an indirect connection 920. This further 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 direct connection 910, which may exist. Additional functionality for the first and / or second lighting devices 110, 120 may be that the first and / or second lighting devices 110, 120 are supplied with energy via the external energy storage device 770 of the additional module 950, or, if the first and / or second lighting devices 110, 120 include an internal energy storage device, that internal energy storage device may be complemented by the external energy storage device 770 of the additional module 950. The additional module may include an external charging unit for connecting a charging device, thereby allowing the first and / or second lighting devices to be charged via the external charging unit. The additional module 950 may also be fitted with an external switching unit, thereby allowing the first and / or second lighting devices to be switched via the external switching unit.

[0183] Another possibility is that there is one indirect connection point 920, 922 between the two lighting devices 110, 120, respectively, to an additional module 950 (Figure 11). In this case as well, another function may be provided for the first and / or second lighting devices 110, 120 via the additional module. Furthermore, the two lighting devices 110, 120 can be indirectly connected to each other via the two indirect connection points 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.

[0184] Preferably, in the case of indirect connectors 920, 922, they are intended to extend through the inside of the handlebar 14, and particularly preferably through the inside of the handlebar 14, from there to the inside of the stem 12. From there, the indirect connectors 920, 922 can exit. From the outside, the indirect connectors 920, 922 can reach the inside of the frame 2, particularly through the head tube 4 of the frame.

[0185] Another possibility is that an indirect connection 924 branches off from the direct connection 910 between the two lighting devices 110 and 120 and extends to an additional module 950 (Figure 12). In this case as well, the two lighting devices 110 and 120 can be functionally complementary to each other and / or provide further functionality via the additional module, and the above description applies to this as well.

[0186] Preferably, in the case of such an indirect connection 924, it is intended to branch off from the direct connection 910 inside the handlebar 14 and reach inside the stem 12. From there, the indirect connection 922 can exit. From the outside, the indirect connection 924 can reach inside the frame 2, particularly through the head tube 4 of the frame.

[0187] Figure 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 handlebars. In this case, the direct connection 910 is designed as a flat ribbon cable, which runs through the inside of the handlebars and is therefore not visible from the outside. The flat ribbon cable has two cable ends, one of which is connected to the inner section 200 of the first lighting device 110, which is inserted into the inside of the handlebars 14, and the other cable end is connected to the inner section 200 of the second lighting device 120, which is also inserted into the inside of the handlebars 14. The cable of the direct connection 910 may have some excess length, so that the first and / or second lighting devices 110, 120 can be detached from the handlebars 14 while the cable is connected.

[0188] Figures 15-16 again show another example of the motorcycle 1 with the first and second lighting devices 110 and 120, as well as the direct connection 910 between the lighting devices 110 and 120 and the indirect connection 920 to the additional module 950. This example is comparable in some respects to Figures 10 and 13.

[0189] However, in the example shown here, the handlebar unit 10 has a handlebar 14 and a stem 12 integrally connected thereto, and the inside of the handlebar 14 and the inside of the stem 12 are in communication, forming a common internal space. Connection parts, in this case a direct connection part 910 and a contact connection part 920, can extend through this common internal space.

[0190] Figures 17-18 again show another example of the motorcycle 1, with the first and second lighting devices 110, 120, and the direct connection 910 between the lighting devices 110, 120 and the indirect connection 920 to the additional module 950 attached. This example is again comparable in some respects to Figures 10 and 13. In the example shown here, the handlebar unit 10 is designed to consist of two parts, as in most of the previous examples, and includes a handlebar 14 and a stem 12 clamped thereto, with an opening in the center of the handlebar 14 facing the inside of the stem 12, so that the inside of the handlebar 14 communicates with the inside of the stem 12 and the indirect connection can extend there.

[0191] This example shows that the indirect connection, in this case the connection 920, may extend inside the front fork 6, particularly through its steerer tube, as needed. This prevents the connection from exiting the stem 12 and reaching the inside of the frame 2 again, for example, via the head tube 4. Rather, the front fork 6 connected to the stem 12 has an opening at its upper end facing the inside of the stem 12, so that the inside of the front fork 6 communicates with the inside of the stem 12, and the indirect connection may extend from the inside of the stem 12 into the inside of the front fork 6. The front fork may further preferably have a further opening facing the inside of the frame 2, so that the indirect connection can reach from the inside of the front fork into the inside of the frame.

[0192] Figure 19-20 shows a lighting system mounted on the handlebars 14 of a motorcycle 1, comprising lighting devices 110, 120, and 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 extend along the outer circumference of the handlebars 14. The direct connection extends through the interior of the handlebars 14. However, it is also possible for the direct connection 910 to extend along the outer circumference of the handlebars 14.

[0193] Figure 21 more precisely illustrates how a connector, in this case an indirect connector 920, extending along the outer circumference of the handlebar 14, can be connected to a lighting device, in this case a first lighting device 110, mounted on the handlebar 14. The connector, in this case an indirect connector 920, can extend between the handlebar 14 and the handlebar grip 20 fixed thereon, to the end face of the handlebar 14 and / or to the outer section 300 of the lighting device. The connector, extending along the outer circumference of the handlebar, can be connected to the lighting device there. The connector, extending along the outer circumference of the handlebar, can be designed entirely or partially as a flat ribbon cable. In the illustrated example, for example, the portion of the connector cable extending below the handlebar grip 20 is designed as a flat ribbon cable.

[0194] Figures 22-24 show a first lighting device 110 that can be functionally connected to a second lighting device 120, particularly via a connecting means 900, according to one embodiment of the present invention.

[0195] Details described below, particularly those relating to the first lighting device 110, also apply to the second lighting device 120, except where otherwise exceptionally. Furthermore, details described below also apply to lighting devices 110, 120 that can be driven independently of each other according to embodiments of the present invention, except where otherwise exceptionally.

[0196] The lighting device 110 comprises an inner section 200 having an inner section diameter 202 and an inner section length 204, and an outer section 300 having an outer section diameter 302 and an outer section length 304. The inner section length 204 is preferably at least twice, and particularly preferably at least four times, larger than the outer section length 304. The outer section diameter 302 is preferably at least 1.25 times, and particularly preferably at least 1.5 times, larger than the inner section diameter 202. Between the inner section 200 and the outer section 300, a transition portion is formed by a radial collar 400, which contacts the end face of the handlebar 14 when the lighting device 110 is attached to the handlebar 14.

[0197] The inner section 200 of the lighting device 110 may include a contact connection 850 for detachably connecting the connecting means 900. Furthermore, the inner section 200 may provide space for an energy storage device, in this case a first energy storage device 750. When installed, the energy storage device is located inside the handlebar 14. The energy storage device 750 may be located between the contact connection 850 and the outer section 300 of the lighting device 110.

[0198] The outer section 300 of the lighting device 110 comprises, in particular, one or more lighting means 600. Preferably, the outer section 300 comprises a forward light 610 that generates a forward luminous flux 130 when mounted. Preferably, the outer section 300 further comprises a rear light 620 that generates a rear luminous flux 140 when mounted. The outer section 300 may further comprise a ground light 630 that generates a ground luminous flux 150 when mounted.

[0199] Figures 25-26 show how the lighting device 110 can be attached to the handlebar grips 20 and / or the handlebars 14. The lighting device 110 includes for this purpose mounting means 500, i.e., a fixing ring 510, fixing screws 520 and screw holes 410, located within the radial collar 400 of the lighting device 110.

[0200] The fixing ring 510 for the lighting device 110 is preferably designed as a handlebar grip fixing ring, so that the handlebar grip is fixed to the handlebar 14 using the handlebar grip fixing ring 22 on the inside and the fixing ring 510 for the lighting device 110 on the outside. The fixing ring 510 is clamped to the handlebar 14 and / or handlebar grip 20 by a device 514 for circumference adjustment. In this case, the fixing ring 510 is preferably fixed to the edge of the handlebar 14 so that the fixing ring 510 forms an end-face contact surface with the end face of the handlebar 14. When the lighting device 110 is attached to the handlebar 14 and / or handlebar grip 20, the lighting device 110 therefore contacts the fixing ring 510 with its radial collar 400.

[0201] The fixing ring 510 has axial screw holes 512 that can be aligned with the screw holes 410 of the radial collar 400 of the lighting device 110, and as a result the lighting device 110 can be screwed to the fixing ring 510 using fixing screws 520.

[0202] The lighting device 110 is preferably constructed to have a plurality of housing parts, in particular an inner housing 250 and an outer housing 350, and a sealing ring 480 located between them as needed, the inner housing preferably includes a radial collar 400 having screw holes 410 for fixing. Preferably, the inner housing 250 may be connected to the outer housing 350 at the same time using fixing screws 520. However, it is also possible that the inner housing 250 is connected to the outer housing 350 in a different way.

[0203] Figures 27 and 28 show further details of the structural design of the lighting device 110, which, as described, has an inner housing 250 and an outer housing 350 in particular.

[0204] The inner housing 250 of the lighting device 110 includes, in particular, an inner housing sleeve 260 in which the energy device of the lighting device 110 can be arranged. The inner housing sleeve 260 terminates on the side facing the outer housing 350, which has an inner housing flange 270, and the outer housing is used on one side to form a radial collar 400 and on the other side to mount a circuit board 430.

[0205] The outer housing 350 of the lighting device 110 has an outer housing end face 380 having a charging connection recess 382 inside, so that the charging unit 700 is accessible at the end face, for example, a charging plug can be inserted. The charging connection recess 382 can be closed using a cover cap 390, which can be connected to the outer housing 350 in a watertight manner, in particular, using, for example, a cover cap seal ring 388.

[0206] As already explained, the details described using this lighting device 110 as an example also apply to independently operating lighting devices. However, conversely, the details described in relation to independently operating lighting devices can also be applied to the lighting device 110 described herein, for example, the cover cap 390 may be formed as shown in Figures 7-8.

[0207] Between the inner housing 250 and the outer housing 350 is an intermediate housing 450, which is integrally fabricated from a particularly transparent material. This transparent intermediate housing 450 forms light covers 656, 666, and 676 for the lights 610, 620, and 630 of the lighting device 110. These light covers 656, 666, and 676 engage with light recesses 370 in the outer casing 360 of the outer housing 350. The intermediate housing 450 further covers components on the circuit board 430, but in the case of the first lighting device 110, it has an axial charging connection opening 452 accessible through a charging connection recess 382 in the outer housing 350. The outer housing 350 rests on the inner housing flange 270, and preferably a sealing ring 480 ensures a watertight connection.

[0208] Figures 29-30 show the circuit board 430 mounted on the inner housing flange 270, along with the components mounted thereon. The lighting device 110 includes a plurality of light sources 650, 660, and 670, each having an assigned light shaper 654, 664, and 676. The light sources 650, 660, and 670 are in contact on the same circuit board 430 as the assigned light shapers 654, 664, and 676.

[0209] The first light source 650 and the first light shaper 654, and preferably the first light cover 656, are adapted to form the front light 610 of the lighting device 110 and generate a forward luminous flux 130. The first light source 650 is designed as a light-emitting diode arranged planarly on the circuit board 430, and its axial emission direction is deflected radially by the light shaper 654, which is designed as a reflector.

[0210] A second light source 660 and a second light shaper 664, and preferably a second light cover 666, are adapted to form a rear light 620 of the lighting device 110 and generate a rear luminous flux 140. The second light source 660 is similarly designed as a light-emitting diode arranged planarly on the circuit board 430, and its axial emission direction is deflected radially by the light shaper 664, which is designed as a reflector.

[0211] A third light source 670 and a third light shaper 674, and preferably a third light cover 676, are adapted to form the ground light 630 of the lighting device 110 and generate a ground luminous flux 150. The third light source 660 is designed as a laser diode that is in contact on the circuit board 430 and emits radially bundled light, which is then spread into a linear emission by a light shaper designed as a linear shaper. The light shaper is mounted rotated by a correction angle φ about its radial axis so that the linear luminous flux extends along the longitudinal direction of the motorcycle 1 when mounted. This compensates for the inclination path of the handlebars 14 with respect to the lateral direction of the motorcycle 1.

[0212] Figures 31-32 again show the first lighting device 110 of a lighting system 100 having two functionally complementary lighting devices 110, 120. In this case, the first lighting device 110 has a charging connection 710 in particular, which is in contact on a circuit board 430 and protected by a removable cover cap 390 from the outer housing 350. For the charging connection 710, for example, USB-PD may be provided.

[0213] The charging connection 710 of the first lighting device 110 can charge both the energy charging 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 connection 710 of the first lighting device 110 functionally complements the second lighting device 120, and as a result, the second lighting device preferably does not require its own charging connection.

[0214] Figures 33-35 show the second lighting device 120 of the lighting system 100, which has two functionally complementary lighting devices 110, 120. The second lighting device 120, like the first lighting device 110, has a contact connection portion 850 located in the inner section 200 to which a connecting means 900 can be connected in order to establish a direct connection with the first lighting device 110 and / or an indirect connection with the additional module 950. As already described, the above description applies to the second lighting device 120 in principle unless otherwise specified.

[0215] However, unlike the first lighting device 110, the second lighting device 120 in this example does not have its own charging connection 710, charging connection recess 382 and cover cap 390 within its outer housing 350. The second energy storage device 760 is charged in this case via the connection 900.

[0216] However, the second lighting device 120 includes a switching unit 800 having a switch 810 in contact on a circuit board 430. The switch can be actuated via an actuation element 820, which in this example consists of two elements. An elastically deformable disc 820 that can be pressed by a user may be placed in an actuation element recess 384 of the outer housing 350 (see Figure 35). This allows pressure pulses to be transmitted to the switch 810 via a further actuation element 820.

[0217] The switching unit 800 of the second lighting device 120 can switch between the lights 610, 620, and 630 of the second lighting device 120 and the lights 610, 620, and 630 of the first lighting device 110. In other words, the switching unit 800 of the second lighting device 120 functionally complements the first lighting device 110, and as a result, the first lighting device preferably does not require its own switching unit.

[0218] Figure 36 shows a lighting device 110 of a lighting system 100 having an internal switch 830, which can be mounted on a handlebar 14. The lighting device 110 that can be mounted on a handlebar preferably includes a handlebar grip 20, which may be secured to the handlebar by, for example, one or more handlebar grip retaining rings. In the illustrated example, the handlebar grip 20 may be secured by an internal handlebar grip retaining ring 22 and an external mounting ring 510 which may also contribute to securing the lighting device 110.

[0219] In this example, the lighting system 100 includes a switching unit 800 having an internal switch 830, specifically designed as a push button, which, in the mounted state of the lighting device, is oriented towards the rear of the motorcycle and is actuated in particular by a radial pressure impulse. In this example, the internal switch is located within the handlebar grip 20, specifically on the side facing the internal handlebar grip retaining ring 22. Thus, the internal switch 830 can be operated particularly with the thumb. The internal switch 830 may be designed, for example, for operation in a turn signal mode, so that one or more of the lights of the lighting means 600 can function as turn signals.

[0220] Of course, the lighting system 100 may have internal switches 830 on each side of the handlebars. In that case, these internal switches 830 may be located on one of the respective lighting devices 110, 120, in particular, on the handlebar grips 20 and / or associated mounting bodies assigned to them.

[0221] Generally, a switching unit for a lighting system may be intended to include one or more thumb-operated switches for switching one or more of the lighting means of the lighting system, in particular for switching them on, switching them off, and / or switching them to various operating modes. For example, it may be intended that the front lights and / or rear lights can be switched on using a thumb-operated switch. For example, it may be intended that the turn signal mode can be switched on by the same or different, in particular, thumb-operated switches.

[0222] The lighting system may include a turn signal mode in which the front lights and / or rear lights of the lighting device function as turn signals. For this purpose, the front lights and / or rear lights may include, for example, light sources designed to produce different light colors. The front lights and / or rear lights may include additional light sources for the turn signal mode, and such additional light sources may be assigned, for example, to the same light shaper as the front lights or rear lights. However, for the turn signal mode, complementary turn signal front lights and / or turn signal rear lights may also be incorporated within the first lighting device and / or second lighting device.

[0223] The light color for the turn signal mode is preferably yellow. The light color for the front lights is preferably white. The light color for the rear lights is preferably red.

[0224] In an advanced form of the present invention, the lighting system may also include a horn function. For this purpose, a piezoelectric component or a loudspeaker may be incorporated into the lighting device.

[0225] Figure 37 shows a two-part embodiment of the lighting device 110. The lighting device 110 comprises a base unit 160 that can be fixed to a tubular handlebar 4 and / or handlebar grip 20, and a light head 170 that can be fixed to the base unit 160.

[0226] The light head 170 may be connected to the base unit 160 by a quick coupling so that it can be quickly removed from the base unit 160 in this case. In contrast, the base unit 160 is attached to the handlebars 14 and / or handlebar grips 20 by mounting means 500 so that the base unit 160 remains firmly attached to the motorcycle when the light head 170 is removed from the base unit 160. The mounting means may include, for example, a retaining ring that can be tightened around the handlebar pipe from the outside so that the base unit 160 is screwed therein, particularly by the flange of the base unit 160.

[0227] Figure 38 shows another two-part embodiment of a lighting device adapted to be mounted on the end face of the handlebar 14. This embodiment corresponds in many respects to the two-part embodiment described above. Thus, the two-part design in particular is consistent in that the light head 170 can be fixed to the base unit 160, and the base unit 160 can be fixed to the handlebar 14 and / or handlebar grip 20.

[0228] The difference is that, in this case, the base unit 160 is firmly attached to the handlebar grip 20 by the mounting means 500. The handlebar grip 20 is fixed to the handlebar tube 14, and as a result, the base unit is also fixed to the handlebar tube 14 via the handlebar grip 20.

[0229] The light head 170 is fixed to the base unit 160 using a mechanical fastening system 180, specifically designed as a quick coupling, using a plug-in configuration as shown here. When the light head 170 is fixed to the base unit 160, it extends beyond the axial end of the tubular handlebar 14. Thus, the light head 170 forms at least a portion of the outer housing 350 of the lighting device 110. In contrast, the base unit 160, when installed, is at least partially inside the handlebar 14. In this way, the base unit 160 forms at least a portion of the inner housing 250 of the lighting device 110.

[0230] The light head 170 and the base unit 160 are further connected using an electrical connection system 190 when the light head 170 is fixed to the base unit 160. This enables an electrical connection between the lighting means 600 located within the light head 170 and the energy storage device 750 located within the base unit 160. In one example, the electrical connection system 190 may be designed as a USB-C plug and USB-C socket.

[0231] The lighting system further has a contact connector 850 located on the base unit 160. In this way, the contact connector 850 may be located inside the handlebar 14 when installed. The contact connector 850 is adapted to connect the base unit 160 of the lighting device to another base unit on the opposite side of the handlebar 14. For this purpose, a connecting means 900 is included for establishing a connection between the illustrated base unit 160 and a second base unit (not shown). The connecting means 900 may be firmly connected to the base unit 160 or detachably connected. In the illustrated example, the connection is made using USB-C.

[0232] The base unit 160 further includes a charging unit 700. In the illustrated example, the charging unit includes a charging connection formed by a USB-C connector. In this example, the charging connection is formed by an electrical connection system. That is, when the light head 170 is removed from the base unit 160, and the connection of the electrical connection system 190 is disconnected, the USB-C connector of the base unit 160 becomes accessible and can be used as the charging connection of the charging unit 700.

[0233] In this case, the charging unit 700 is designed as a common charging unit. By connecting the charging device to the charging connection, both the energy storage device 750 of the first lighting device and the energy storage device of the second lighting device, which is connected to it via the connecting means 900, can be charged. Therefore, the contact connection 850 and the connecting means 900 are specifically adapted to transmit the charging current.

[0234] Figures 39 and 40 show a further two-part embodiment of the lighting device. This embodiment corresponds in many respects to the two-part embodiment described above. Thus, the two-part design, in particular, is consistent in that the light head 170 can be fixed to the base unit 160, and the base unit 160 can be fixed to the handlebar 14 and / or handlebar grip 20.

[0235] Furthermore, the light head 170 is also consistent in that it can be fixed to the base unit 160 by a mechanical fastening system 180 designed as a quick coupling by insertion. For this purpose, the mechanical fastening system 180 includes cooperating fastening means 182 within the light head 170 and the base unit 160.

[0236] In this case, the base unit 160 is fully insertable into the tubular handlebar 14. Therefore, in this case, the base unit does not have a flange. In this case, the base unit 160 is secured by mounting means 500, which are designed as thin plates adapted to be pressed against the inside of the handlebar 14.

[0237] Figure 41 shows a further two-part embodiment of the lighting device. This embodiment corresponds in many respects to the two-part embodiment described above. Thus, the two-part design, in particular, is consistent in that the light head 170 can be fixed to the base unit 160, and the base unit 160 can be fixed to the handlebar 14 and / or handlebar grip 20.

[0238] In this case, the light head 170 can be magnetically fixed to the base unit 160. The light head 170 and the base unit include cooperating fixing means 182 for magnetic fixing. In this way, the cooperating fixing means 182 form a mechanical fixing system 180 for fixing the light head 170 to the base unit 160, thereby achieving quick coupling again.

[0239] The light head 170 may be mounted to be rotatable in the axial direction so as to change the angle of the principal direction of forward light emission relative to the vertical. This may also be contemplated in other embodiments.

[0240] Furthermore, it is intended that, for example, the energy storage device 750 located within the base unit 160 can be removed from the base unit 160. This allows the base unit 160 to remain attached to the handlebar 14 and to remain connected to the second lighting system via the connecting means 900 when the energy storage device 750 is removed. Removal of the energy storage device 750 from the base unit allows the energy storage device to be charged, for example, outside the base unit 160, for example, in an external charging tray.

[0241] That is, for example, a charging tray may be included that is adapted to charge both energy storage devices 750, 760 of a lighting device that can be mounted on both sides. In the illustrated example, the energy storage device 750, together with the charging unit 700, forms a removable unit.

[0242] Figure 42 shows a further two-part embodiment of the lighting device. This embodiment corresponds in many respects to the two-part embodiment described above. Thus, the two-part design, in particular, is consistent in that the light head 170 can be fixed to the base unit 160, and the base unit 160 can be fixed to the handlebar 14 and / or handlebar grip 20.

[0243] In this case, the light head 170 includes an energy storage device 750. The light head 170 is further insertable into the base unit 160. In other words, the light head 170 is axially inserted into the base unit 160, which is at least partially located inside the handlebar 14, when fixed in place.

[0244] The energy storage device 750 can be detachable from the light head 170. For example, the energy storage device 750, together with the charging unit, can again form a unit that can be detachably attached to the light head 170, for example, by USB-C.

[0245] Figures 43 and 44 show a base unit 160 for mounting to the end face of the handlebar 14. In many respects, the base unit corresponds to the base unit of the two-part embodiment described above. The base unit 160 can also be used without the light head. Thus, the base unit 160 forms an extension unit 111 for a motorcycle, preferably a second extension unit is intended, so that both extension units form an extension system.

[0246] The base unit 160 comprises an energy storage device 750 and a charging unit 700. More preferably, a contact connection portion 850 is intended for a robust or removable contact of the connecting means 900, thereby enabling connection to a second base unit (not shown).

[0247] The base unit, or extension unit, may preferably include at least one end-face charging unit 700 designed as a common charging unit. Furthermore, a cover cap 290 for the end face may be provided.

[0248] Figure 45 shows a motorcycle fitted with a lighting system 100, which includes a first lighting device 110 and a second lighting device 120. In the illustrated example, the lighting devices 110 and 120 are each designed to consist of two parts, so that the light heads can be removed from a rigidly mounted base unit.

[0249] The lighting devices 110 and 120 are connected by connecting means 900 that extend inside the tubular handlebar 14. The connecting means 900 allows for common charging for the two lighting devices 110 and 120. For this purpose, a common charging unit is included.

[0250] In the illustrated embodiment, and in other embodiments where the connecting means can be used, a common charging connection may be provided at one or more locations. The common charging unit and / or common charging connection may be incorporated, for example, into one of the two lighting devices. However, as shown in the illustration, the common charging unit 700 may also be located outside the lighting devices 110, 120, for example on a motorcycle, for example on a protruding part of the motorcycle. In this example, the external charging unit 700 is connected to the energy storage devices of the two lighting devices via a branch of the connecting means 900.

[0251] Figure 46 shows a motorcycle fitted with an expansion system 101, which includes a first expansion unit 111 and a second expansion unit 121, where the expansion units 111 and 121 are designed as base units as described above. Thus, the expansion units correspond in many respects to the base units of the lighting system described above.

[0252] The extension units 111 and 121 are connected by connecting means 900 that extend inside the handlebars 14. Furthermore, a common charging unit 700 is envisioned, which may be located, for example, within the handlebars 14.

[0253] In this embodiment, however, as in the embodiments described above, it may be intended that a common charging unit 700 is designed to supply energy for further devices that can be attached to, for example, a motorcycle. For this purpose, the common charging unit 700 may preferably have a power supply connection to provide energy for further devices. However, it is also possible that an internal or external charging connection can contribute to energy supply simultaneously. For this purpose, for example, a USB-C port adapted for charging on the one hand and for energy supply on the other hand may be used.

[0254] Therefore, a device such as a smartphone can be charged, particularly when such a device is mounted on a motorcycle, via the charging unit 700, in particular an internal or external charging unit, and / or a corresponding charging connector. For example, an inductive charging holder for a smartphone can be connected to a supply connector or a charging connector adapted for energy supply.

[0255] Figure 47 shows an embodiment of the illumination device 110 having an adjustment device 680 adapted to adjust the correction angle φ of a third optical shaper 674, which is specifically designed as a linear shaper. For this purpose, the third optical shaper 674 is supported so as to be rotatable around a radial axis. In this case, the inner housing flange 270, and therefore the inner housing 250, can be rotated axially relative to the outer housing 350 and the fixing ring 510, by easily loosening a mounting means, which is a screw that engages into the outer housing 350 through a fixing ring 510, and is designed, for example, as a projection extending radially from the inner housing flange 270, via the adjustment device 680. For this purpose, the inner housing flange 270 further has a slot through which a screw extends, which simultaneously functions as a limit for adjustment. The correction angle φ can be adjusted through the rotation of the inner housing 250 by an engagement pin 681 extending axially from the inner housing flange 270 engaging into a lateral engagement opening of the third optical shaper 674. In this embodiment, as in other embodiments, the circuit board 430 may be fixed to the outer housing 350 and / or the intermediate housing 450.

[0256] Figure 48 shows a motorcycle 1 with lighting devices 110 and 120 attached, and the ground beam 150 is designed to be rotatable, in particular, around the vertical. For this purpose, the correction angle φ can be adjusted, in particular, as previously stated. Thus, advantageously, the ground beam 150, in particular designed as a laser beam, can be adapted to the respective inclined paths of specific handlebars 14 with respect to the transverse direction of the motorcycle 1 (see, for example, lighting device 110).

[0257] Figures 49 and 50 show a lighting system 100 mounted on a motorcycle 1, in which two lighting devices are mounted on opposing end faces of the handlebars. The illustration shows the total illumination resulting from the superposition of two forward luminous beams. Both the first and second illuminating devices, more precisely their forward lights, generate forward luminous beams having primary radiation directions 132 and 134, respectively. From the two forward luminous beams, a total forward luminous beam 136 is generated.

[0258] The front lights of the two lighting devices are adjusted so that a total front light beam 136 suitable for front lighting is generated, as a result, a better forward visibility for the driver of the motorcycle is ensured. Therefore, the two front lights do not contribute only to making the motorcycle more visible to other road users. The total front light beam 136 is preferably designed such that there is a total luminous intensity having a certain minimum value at the central position 138. This value can be, for example, at least 50% of one luminous intensity of the maximum luminous intensity (Fig. 49), or can be a larger value such as at least 75%, 100% or 125%, etc., and as a result, at the central position 138, a plateau or even an absolute maximum value of luminous intensity occurs.
