Description

Technical Field

[0001] The invention relates to a positioning lamp for a vehicle, a headlamp and a vehicle according to the appended claims. Background Art

[0002] Due to traffic regulations, position lights for vehicles must emit light both in a main emission direction, for example along the roadway, and laterally, for example to the left and right of the roadway or to the periphery of the roadway.

[0003] Here, the emission angle of the positioning light or the positioning lighting device should satisfy a lateral emission angle of 80° relative to the main emission direction, so that the positioning light can be clearly identified even from a lateral position of the corresponding vehicle.

[0004] Known positioning lamps or boundary lighting lamps are optimized for a single side of the vehicle and emit light to a main emission direction and a single side. Accordingly, usually two positioning lamps act together so that light is emitted to two sides.

[0005] Furthermore, particularly in the case of mopeds such as motorcycles, the available installation space is very limited. Summary of the invention

[0006] The object of the present invention is to provide a compact and safe positioning light for a vehicle.

[0007] Therefore, according to a first aspect of the present invention, a positioning light for a vehicle is proposed.

[0008] The proposed positioning lamp comprises at least one light source, a certain number of first optical waveguides arranged on a first side, and a certain number of second optical waveguides arranged on a second side opposite to the first side, wherein the corresponding first optical waveguide is configured to emit the light emitted by the at least one light source both in a main emission direction and in a first area in the direction of the certain number of second optical waveguides, the main emission direction extending along a main axis extending perpendicularly to an intermediate axis connecting the first side and the second side, and wherein the corresponding second optical waveguide is configured to emit the light emitted by the at least one light source both in the main emission direction and in a second area in the direction of the certain number of first optical waveguides.

[0009] The proposed positioning light, which can be a boundary light, for example, is based on a plurality of light conductors which are arranged at least partially opposite one another.

[0010] The respective optical waveguides of the proposed positioning light respectively emit in a main emission direction, i.e., for example, forward or in the direction of the roadway, and on one side in a lateral emission direction or lateral emission area. Here, different optical waveguides emit laterally toward the optical waveguides respectively located opposite each other, so that the proposed positioning light emits light along the main emission direction and to both sides, or can be identified as emitting light from the main emission direction and from a second side (both sides) relative to the main emission direction.

[0011] It can be provided that the light beams emitted laterally from the first optical waveguide and the light beams emitted laterally from the second optical waveguide intersect each other. That is, the first optical waveguide and the second optical waveguide are designed and arranged relative to each other in such a way that the light beams emitted laterally from the first optical waveguide and the light beams emitted laterally from the second optical waveguide intersect each other, in particular in the middle above the positioning light.

[0012] In order to ensure that the proposed positioning light can be clearly identified from positions oriented laterally relative to the main emission direction, the optical waveguide of the proposed positioning light each covers a lateral area relative to the main emission direction. This means that the positioning light or the light beam emitted by the positioning light can be seen from any position in the lateral area.

[0013] In order to achieve the proposed positioning light being visible from two opposite sides given the limited installation space geometry, the optical waveguide is, for example, arranged and configured such that the light beams emitted laterally by the optical waveguide intersect, in particular in a two-dimensional view. In this case, the optical waveguides are directed laterally toward one another or inwards, for example toward the center of the positioning light. In particular, the optical waveguides can be tilted relative to one another so that they laterally emit light beams extending at an angle, which therefore intersect one another in their distribution.

[0014] As an alternative to a beam geometry that crosses one another, the optical waveguide of the positioning lamp can be designed in such a way that the laterally emitted beams extend parallel to one another but in opposite directions.

[0015] Therefore, not the light conductor close to the corresponding side, but the light conductor away from the corresponding side can be identified as emitting from the corresponding side. This means that the cover of the positioning light or the corresponding light conductor of the positioning light can be lowered outwardly towards the side direction and thus designed aerodynamically advantageously.

[0016] Furthermore, the positioning lamp or the corresponding light conductor can be designed to rise inwardly in the direction of the center of the positioning lamp, thereby providing a light-emitting surface that is clearly recognizable from a lateral position with respect to the positioning lamp. Thus, the positioning lamp can be formed such that it has its highest point at the location closest to the center of the positioning lamp and has its lowest (flattened) point at the corresponding outer end.

[0017] Alternatively or additionally, the respective optical waveguide can be designed to be inclined so that a light beam emitted from the optical waveguide is transmitted over (above) the respective opposite optical waveguide or underneath the respective opposite optical waveguide.

[0018] It may also be provided that a distance between the certain number of first optical waveguides and the certain number of second optical waveguides is less than or equal to 75 millimeters.

[0019] When the distance between a plurality of luminous bodies (eg optical waveguides) is less than or equal to 75 mm, the luminous bodies form a composite body and together form a single positioning lamp.

[0020] It can also be provided that the first region and the second region are each formed between a main emission direction and an outer boundary line extending at an angle of at least 80° relative to the main emission direction.

[0021] By covering the luminous area at an angle of 80° in each case, the legal requirements for positioning lights are met, so that the proposed positioning light is suitable for road traffic.

[0022] It can be provided that each optical waveguide is light-conductingly coupled to a corresponding light source.

[0023] A plurality of light sources for a plurality of light conductors can realize particularly intense and possibly also mutually independent illumination of the light conductors. Thus, complex illumination patterns can also be realized by a plurality of illumination sources, wherein, for example, only one side illuminates or can be recognized as illuminating.

[0024] It can also be provided that the positioning light, in the activated state, emits light in a main emission direction and in each case over an arc of at least 80° to two opposite side surfaces, wherein the two side surfaces point outwards when viewed in the main emission direction.

[0025] By means of the positioning lights, which respectively emit light over an arc of at least 80° toward two opposite sides, an arc of at least 160° is illuminated, so that the positioning lights are visible from a wide area.

[0026] It can also be provided that the respective first optical waveguide has a structured surface which is configured to guide light to the first region, and the respective second optical waveguide has a structured surface which is configured to guide light to the second region.

[0027] In order to guide the light to the corresponding first area so as to emit the light laterally, a structured surface may be provided, which, for example, includes a certain number of stripes or squares, which refract the corresponding light beam and guide it to the first area or accumulate it in the first area. For example, a plurality of stripes may be provided, and a flat area may be provided between each of the two stripes.

[0028] It can also be provided that the positioning light includes a single first optical waveguide and a single second optical waveguide, wherein the first optical waveguide includes a first main light area and a first light area, and the second optical waveguide includes a second main light area and a second light area, the first main light area is configured to emit the light emitted from the at least one light source both in the main emission direction and toward the first area toward the second optical waveguide, the second main optical waveguide is configured to emit the light emitted from the at least one light source both in the main emission direction and toward the second area toward the first optical waveguide, and the first optical waveguide and the second optical waveguide are configured to emit the light emitted from the at least one light source only along the main emission direction.

[0029] By configuring the individual regions to emit light that is recognizable from a side position, complex light geometries having a plurality of luminous regions with different emission characteristics can be realized with a small number of light conductors.

[0030] According to a second aspect, the proposed invention relates to a headlamp, wherein the headlamp comprises a low beam and a high beam in addition to a position light.

[0031] Due to the positioning light according to the invention, a corresponding headlamp can be designed to be particularly compact and thereby fulfil all requirements for a lighting element which is necessary for road traffic.

[0032] For example, it may be provided that the headlight is a motorcycle headlight.

[0033] Due to the compact positioning light, the proposed headlamp is particularly suitable for motorcycles, in particular motorcycles. Here, due to the positioning light according to the invention, the headlamp can be particularly aerodynamically designed, i.e., for example, particularly compact and / or outwardly tapered, thereby optimizing the driving stability of the motorcycle.

[0034] According to a third aspect, the proposed invention relates to a vehicle, wherein the vehicle comprises the proposed possible design of the positioning light.The proposed vehicle may be a moped, in particular a motorcycle.

[0035] The advantages described in detail with respect to the positioning lamp for a vehicle according to the first aspect of the invention also apply to the headlamp according to the second aspect of the invention and to the vehicle according to the third aspect of the invention.
