[0004] wherein the plurality of transparent elements are defined by at least one parent group of transparent elements, said parent group being divided into at least two subgroups, wherein at least one, preferably at least two, transparent elements define a first subgroup, and wherein at least one, preferably at least two, different transparent elements that are not part of said first subgroup define a second subgroup.
[0005] Furthermore, the invention relates to a vehicle comprising a lighting system. Background Art
[0006] Known in the prior art are lighting systems for vehicles that include a light-emitting device and a vehicle body part to be illuminated by the light-emitting device. When the vehicle body part includes sections that should be illuminated and sections that should not be illuminated (for example, to achieve a dynamic lighting effect with a specific pattern), the lighting system's light-emitting device typically includes multiple light sources, with each section of the vehicle body part to be illuminated being associated with a specific light source. A disadvantage of such a system is that it requires a large number of light sources that must be individually controlled. Essentially, the number of light sources must be equal to or greater than the number of illuminated sections.
[0007] The object of the present invention is to provide a lighting system which improves the illumination of vehicle body parts. Summary of the Invention
[0008] To achieve this purpose, the lens element is configured to redirect a first light beam of the first light source towards a first subset of transparent elements and to redirect a second light beam of the second light source towards a second subset of transparent elements, so that in an operating state in which the first light source and the second light source emit light, the first subset of transparent elements and the second subset of transparent elements are illuminated by their respective light sources, and in an operating state in which only one of the at least two light sources emits light, only one of the at least two subsets of transparent elements associated with the light source that emits light is illuminated.
[0009] This has the advantage that the first subgroup is illuminated by the first light source, and the second subgroup is illuminated by the second light source, thereby reducing the number of required light sources. Specifically, the plurality of transparent elements in the first subgroup can be illuminated by the first light source, which can include multiple (e.g., two, three, four, or more) transparent elements. The first light source can be a single light source, with the light directed toward the first subgroup via a lens element. Furthermore, the plurality of transparent elements in the second subgroup can be illuminated by the second light source, which can include multiple (e.g., two, three, four, or more) transparent elements. The second light source can be a single light source, with the light directed toward the second subgroup via a lens element. In other words, the number of illuminated transparent elements can exceed the number of light sources, and thus the system becomes more efficient by requiring fewer light sources. This means that the lighting system according to the present invention can be less expensive and simpler to control. Along the main direction x of light propagation, the distance between the at least two light sources and the lens element can be approximately 10 mm. Along the main direction x of light propagation, the distance between the lens element and the vehicle body component can be between 10 mm and 100 mm, preferably 20 mm. Two adjacent transparent elements can be spaced apart from each other in a main plane of the body part (the main plane being orthogonal to the main direction of light propagation), the distance preferably being between 10 mm and 300 mm, in particular 22 mm. The lens element can be a biconvex lens, a plano-convex lens, a spherical lens or an aspherical lens. In the present disclosure, light propagating in a specific direction does not mean that the light rays are parallel to each other and to a straight line representing a specific direction (e.g., an optical axis). The light source in the present disclosure can have a Lambertian radiation characteristic, and the emitted light propagates along a direction that can be represented by the distance between two objects, such as a light emitting device and a lens element or a lens element and a body part.

[0049] Figure 1 A schematic front view of a lighting system 1 for a vehicle is shown. The lighting system includes a light-emitting device 2, which comprises at least two individually controllable light sources 3a, 3b. The light sources 3a, 3b are configured to emit light along a primary direction x of light propagation. In the illustrated embodiment, the light sources 3a, 3b are configured as multi-chip LEDs, with the first light source 3a corresponding to a first chip of the multi-chip LED and the second light source 3b corresponding to a second chip of the multi-chip LED.
[0050] The light emitting device 2 includes a lens element 4, which is arranged downstream of the at least two light sources 3a, 3b along the main direction of light propagation x. The lens element 4 is configured to receive a first light beam from a first light source 3a of the at least two light sources 3a, 3b and emit the first light beam along the main direction of light propagation x. The lens element 4 is also configured to receive a second light beam from a second light source 3b of the at least two light sources 3a, 3b and emit the second light beam along the main direction of light propagation x.
[0051] Figure 2 A detailed view of an embodiment of a light emitting device 2 is shown. In the embodiment shown, the light source 3 of the light emitting device 2 comprises a luminescent phosphor layer (with Figure 1 ), which is separated into at least two luminous parts by a non-luminous separation layer. Due to the separation of the phosphor layer, the light source 3 has two different luminous areas and is therefore similar to a multi-chip LED in terms of luminous characteristics and functions.
[0052] The light source 3 (which may alternatively comprise a multi-chip LED as described above) is mounted on a light source holder 8, which is arranged relative to the lens element 4 such that light emitted by the light source 3 propagates along the optical axis OA of the lens element 4 toward the vehicle body component 5 (described further below). The light source holder 8 and a peripheral portion of the lens element 4 form a housing surrounding the light source 3, the peripheral portion being optically inactive. The light source holder 8 includes a mounting surface 8a to which the light source 3 is mounted.

The distance D between the lens element 4 and the body part 5 is preferably between 10 mm and 100 mm, in particular 20 mm.
[0058] Figure 3 Different embodiments of a vehicle body component 5 are shown. A transparent element 7 is covered by an opaque section 6. Three gaps are formed in the opaque section 6, which have a specific form and are configured to allow light to pass through. Alternatively, as described above, each transparent element 7, 7' of the plurality of transparent elements 7 is preferably completely surrounded by the opaque section 6 of the vehicle body component 5.
[0059] The lens element 4 is configured to refract the first light beam and the second light beam so that the refracted first light beam and the refracted second light beam respectively propagate towards the optical axis OA of the lens element 4, preferably converge. In the embodiment shown, the lens element 4 comprises a projection lens that projects the light of the light sources 3, 3a, 3b onto the rear surface of the vehicle body part (the projection lens 4 reflects the light image generated by the light emitting device 2). This can be Figure 1 As can be seen in FIG, light source 3a is located on the right and illuminates transparent element 7 of SG1 located on the left. On the other hand, light source 3b located on the left illuminates transparent element 7' of SG2 located on the right.
[0060] Figure 4 Another embodiment of the lighting system 1 is shown, wherein the lighting system 1 comprises a plurality of light emitting devices 2, and a plurality of transparent elements 7 are defined by a plurality of parent groups PG.
[0061] Figure 4 A radiator grille is shown as an example of a vehicle body component 5. A total of seventeen parent groups PG of transparent elements 7 are embedded in the opaque sections 6. Three of these parent groups PG are shown in three dashed circles, which show enlarged views of the corresponding parent groups PG.
