Description

TECHNICAL FIELD

[0001] The invention relates to a lighting device for a helmet, for example a bicycle helmet. Modern bicycle helmets can have a lighting device, for example a red tail light, in order to make the wearer of the bicycle helmet better protected, especially in dark situations, in road traffic, since the wearer is more visible and thus more easily seen. BACKGROUND

[0002] In the prior art, a bicycle helmet is known from the document DE 20 2021 104 042, in which there is a detachable electronics device with a tail light and a corresponding indicator light. Here, the helmet has a recess, which is preferably located on the rear side of the helmet, which is adapted to correspondingly receive the electronics device with the tail light and the indicator light. Thus, there is a predefined receiving surface here, in which the electronics device can be firmly fitted, but at the same time can also be detached again. However, there must be a helmet here with corresponding receiving means in order to be able to correspondingly install the tail light here as well. With existing helmets, no retrofitting is possible here. UTILITY MODEL CONTENT

[0003] It is therefore an object of the invention to provide a lighting device which can be easily fixed to a helmet in a releasable manner and with which existing helmets can also be easily retrofitted.

[0004] The lighting device according to the invention has a light-emitting section, a first fixing device and a second fixing device, which can be releasably connected with the first fixing device. The second fixing device can be releasably connected with the first fixing device. The second fixing device is thus adapted to be mounted at the helmet. The first fixing device is then connected with the lighting device and the second fixing device is variable, for example can be mounted at the helmet, for example by an adhesive connection. The lighting device can thus be mounted at the helmet without the need for special receiving means, so that existing helmets can also be correspondingly retrofitted with the lighting device. Furthermore, such a fixing solution represents a very simple implementation, in which case the helmet can be designed without complex components, which saves additional components, so that the helmet remains as light as possible.

[0005] Preferably, the lighting device also has a curved section, which is adapted to lie against a curved surface of the helmet. The first fixing device is arranged at the curved section. Such a design can make it possible for the lighting device to also be mounted at a curved rear side of the helmet, so that the lighting device can be used as a tail light for the helmet, preferably a bicycle helmet.

[0006] Preferably, the first and the second fixing means have components of a hook-and-loop connection. Thus, the first and the second fixing means can represent respective strips which jointly form a Velcro. Preferably, one of the first and the second fixing means can have a strip with barbs on one side, and the respective other of the first and the second fixing means thus has a strip with loops on one side. Thus, one fixing means has hook components and the other fixing means has loop components. A simple, space-saving and in particular cost-effective connection can thus be achieved.

[0007] Preferably, the first fixing means is mounted on the curved section by means of an adhesive connection. This is a simple, lightweight, cost-effective and in particular secure connection.

[0008] Preferably, the second fixing means has adhesive means, for example an adhesive strip, on the side opposite to the side on which the first fixing means can be connected.

[0009] Thus, the second fixing means can easily be mounted at an existing helmet, for example by means of a double-sided adhesive strip, without a pre-fabricated receiving device being required here.

[0010] Preferably, the lighting device has a battery receptacle. The battery receptacle serves to supply the lighting device with energy. However, a rechargeable battery can also be integrated in the lighting device, which can then be charged by means of a socket or an inductance.

[0011] Preferably, the light-emitting section is adapted for emitting red light. This can achieve that the lighting device is usable as a tail light of a helmet, for example a bicycle helmet.

[0012] Preferably, the light-emitting section has an area of at least 2 cm 2 , further preferably at least 4 cm 2 , still further preferably 6 cm 2 , and most preferably at least 10 cm 2 . This is a sufficiently large area, so that the lighting device is suitable for use as a tail light of a bicycle helmet.

[0013] Preferably, the lighting device is then used as a tail light of a helmet or a bicycle helmet.

[0014] The system according to the application consists of a lighting device as described above, and a helmet, wherein a second lighting device is mounted at the helmet. Preferably, the second fixing means is mounted on the back side of the helmet, so that the lighting device can be used as a tail light. BRIEF DESCRIPTION OF DRAWINGS

[0015] In the following, embodiments of the application are described in detail with reference to the drawings.

[0016] Figure 1 A symmetrical view of a lighting device according to the application is shown.

[0017] Figure 2 An exploded view of the system as a helmet and lighting device is shown in an isometric view.

[0018] Figure 3 A helmet is shown from the rear, on which a lighting device according to the application is mounted.

[0019] Figure 4 A partial view of the exploded view is shown again in an isometric view, in which the lighting device is not connected with the helmet.

[0020] Figure 5 A front view of the lighting device according to the application is shown. DETAILED DESCRIPTION

[0021] In Figure 1 the lighting device 1 can be seen, which has a light-emitting section 2 and on the opposite side a curved section 4, in which a first fixing device 5 in the form of a Velcro strip is mounted. In this embodiment, the entire lighting device 1 has a curved shape. The lighting device 1 is relatively flat and thus relatively small in construction, which achieves weight reduction.

[0022] In Figure 2 the helmet 10 can be seen, at which a second fixing device 11 in the form of a Velcro strip is mounted. Furthermore, it can be seen here that the lighting device 1 is in an unmounted state. However, it can also be seen that the lighting device 1 fits the second device 11 exactly.

[0023] In Figure 3 it can be seen that the lighting device is mounted on the rear side of the helmet 10.

[0024] In Figure 4 the second fixing device 11 in the form of a Velcro strip is shown, which is mounted at the back side of the helmet 10. The lighting device 1 can also be seen, one side of which here is the light-emitting section 2 and the other side is the curved section 4, which is adapted to lie against the area of the helmet 10 at which the second fixing device 11 is mounted. A battery receptacle 3 is also provided on the bottom side of the lighting device 1.

[0025] Figure 5 A view from the rear of the lighting device 1 is shown. As can be seen, the first fixing device 5 is mounted at the curved section 4, but the area of the first fixing device 5 is slightly smaller than the area of the curved section 4. A battery receptacle 3 is also provided on the bottom side of the lighting device.

[0026] The application is not limited to the above-described embodiments. Any other feasible hook-and-loop fastener can also be used, for example a Pilzkopfband or a Veloursband, or two Pilzkopfbands, or extruded hooks. The adhesive part (here: hooks) and the looped part (here: loops) can be arbitrarily interchanged, independently of whether the adhesive part is embodied on the first fixing means 5 or on the second fixing means 11. Furthermore, in the case of the second fixing means 11, there can also be bare spots on the helmet, for example slight recesses or the like. This makes the corresponding connection more secure and makes it less likely that an undesired falling-off or detachment will occur.
