[0007] The publication DE 10 2012 017 596 A1 describes a lighting device for a vehicle with several separate light sources emitting light of different colors and several separate light guides assigned to the light sources in such a way that the light emitted in different colors is coupled into the light guides via light coupling surfaces, so that at least two light guides carry light of different colors, wherein the colored light of the at least two light guides is coupled out at first light coupling surfaces of the at least two light guides.

[0008] A surface light for an aircraft cabin is described in the publication DE 10 2011 013 206 A1 and comprises a light box and a light source whose light is coupled into the light box, wherein a rear wall of the light box is designed to be reflective and the front wall of the light box has optical elements for directed emission of the light.

[0009] JP 2012 - 8 409 A discloses a lighting device of a projector with light sources and a light guide device for the light sources, wherein the light guide device has a first body made of transparent material and a second body made of transparent material, wherein light from the light sources is to be guided through the first and second bodies.

[0010] DE 10 2012 112 076 A1 discloses a lighting device for motor vehicles.

[0011] Against this background, one objective of the invention was to provide light originating from or emitted by various light sources to a viewer of a vehicle in a homogeneously illuminated manner through a light-emitting surface.

[0012] To solve the problem, a lighting device with the features of independent claim 1 is presented.

[0013] The embodiments of the lighting device are described in the dependent patent claims and the description.

[0014] The lighting device according to the invention, which is to be used for the exterior lighting of a vehicle, has at least two different and / or independent light sources and a light guide for the at least two light sources, wherein the light guide comprises a first body made of transparent material and at least one second body made of volume-diffusing and thus translucent material, wherein light from at least one first light source is to be coupled into the first body and guided or transported through the first body of the light guide. Light from at least one second light source is first to be coupled into the at least one second body and guided or transported through the at least one second body.After passing through the at least one second light source, the light is usually coupled into the first body and then guided or transported through the first body of the light guiding device.

[0015] Thus, the light from at least one first light source and the light from at least one second light source, after having previously passed through or through at least one second body, are to be guided together through the first body. The material of the second, volume-preserving body has a high opacity, whereas the material of the at least one first body, which is transparent, generally has no opacity or at most a very low opacity.

[0016] In the light-guiding device, the first body is bounded in longitudinal section by two parallel bases and two legs, with each base intersecting two legs and each leg intersecting two bases. Light to be emitted from the at least one first light source is guided or transported into the first body through a first leg and then between the two bases of the first body, exiting the first body through a second leg. Light to be emitted from the at least one second light source, after passing through the at least one second body, is coupled into the first body through a first base of the first body and then guided or transported between the two bases.The light then exits the first body through the second leg. Accordingly, the second leg of the first body is designed as a common light-emitting surface for light that originates from at least two light sources and is mixed within the first body. Thus, the second leg of the first body is configured as a common light-emitting surface for light from all light sources.

[0017] In the first body, a principal ray axis is provided or defined, passing through the first body and typically running parallel between the two longitudinal axes of the first body. Light from the at least one first light source is directed towards or parallel to the principal ray axis. Light from the at least one second light source is initially coupled into the at least one second body perpendicular to the principal ray axis and then directed through the first body parallel to the principal ray axis.

[0018] Furthermore, the at least one second body is also bounded in longitudinal section by two parallel bases and two legs, with each base intersecting two legs and each leg intersecting two bases. Light from the at least one second light source is coupled into the at least one second body through a first leg and guided or transported between the two bases. The light exits the at least one second body through a second leg. Subsequently, light that was originally emitted by the at least one second light source is coupled into the first body through the first base of the first body.

[0019] Typically, the first body and at least one second body are connected to each other. In this regard, it is provided that the second leg of the at least one second body, which is usually rectangular in longitudinal cross-section, is connected to the first longitudinal side of the first body.

[0020] In the embodiment of the light guiding device, the first body has a longitudinal cross-section in the form of a right-angled trapezoid with two base sides arranged parallel to each other and two legs, wherein the first leg is oriented obliquely to the two base sides arranged parallel to each other as an input for light from the at least one first light source, and wherein the second leg is oriented perpendicularly to the two base sides as an output for light, which is originally emitted by all light sources and is mixed and / or superimposed in the first body.

[0021] The first leg of the first body and a base of at least one second body are oriented towards each other at an acute angle.

[0022] Light from at least one first light source is initially coupled into the first body from the outside through the first leg and then guided out of the first body through the second leg. Light from at least one second light source, after passing through the at least one second body, is initially coupled into the first body from the outside through the first base, which is oriented at an acute angle to the first leg, e.g., an angle of 45°, is then typically reflected off an inner surface of the first leg, passes through the first body, and is then guided out of the first body through the second leg.

[0023] In a further embodiment of the light-guiding device, at least one additional body is assigned to at least one of the two legs of the first body as a light element. This additional body is unstructured or amorphous and comprises light-scattering material, at least one optical module (e.g., at least one micro-optical module and / or at least one prism), and / or at least one textured or rough surface. The additional body is configured to align light rays, either as an alternative or supplementary function. The additional body has a first and a second leg and its longitudinal cross-section is a parallelogram, e.g., a rectangle, a right-angled trapezoid, or a triangle.

[0024] The at least one additional body comprises a first leg through which light is to be guided or transported into the additional body, and a second leg through which light is to be guided or transported out of the additional body. If the at least one additional body is associated with the first leg of the first body, its second leg faces the first leg of the first body, whereby light from the first light source is first to be guided or transported through the first leg of the at least one additional body, out of the second leg of the at least one additional body, and coupled into the first body through the first leg of the first body.If the at least one additional body is assigned to the second leg of the first body, its first leg faces the second leg of the first body, wherein light, which is originally to be emitted by all light sources, is to be guided or transported out of the first body through the second leg of the first body after passing through it, the light then exits through the second leg of the at least one additional body, the second leg of the additional body serving as a common light-exiting surface for light from all light sources.

[0025] Typically, a first optical signal is provided using light from at least one primary light source, and a second optical signal is provided using light from at least one secondary light source. The light from both light sources differs, for example, in color, in at least one frequency of their respective light spectrum, and / or in the temporal progression of a shape or signal form of a respective signal. Different functions can be optically represented simultaneously by using different light from different light sources.

[0026] The at least one light source includes at least one light-emitting diode or is designed as a light guide.

[0027] Furthermore, light from at least one light source must be coupled into the light guiding device through a first leg of a body of the light guiding device and guided or transported through the light guiding device.

[0028] The at least one light source is arranged directly in front of the first leg of a body, i.e., the first body, the at least one second body, or an additional body, of the light guiding device, wherein light emanating from the at least one light source is to be coupled and guided or transported directly through this first leg of the respective body into the light guiding device.

[0029] Alternatively, the at least one light source is directed away from the first leg of the respective body of the light guiding device and therefore not directly onto a first leg of the respective body. In this case, light from the at least one light source is projected perpendicularly onto a surface of the first leg via a reflector and coupled into the light guiding device through this first leg of the respective body.

[0030] The lighting device has a cover plate which is arranged behind a second leg of a body, i.e. the first or the additional body, from which the light, originally from both light sources, exits the light guiding device and is then to be guided or transported through the cover plate as a common light exit surface for light from all light sources.

[0031] The lighting device is intended for the exterior lighting of the vehicle, usually a motor vehicle. At least one light source must be used to provide a signal for a tail light, a side marker light, a brake light, and / or a direction indicator. Thus, a light-emitting surface, i.e., a second leg of a body of the light guide device or the cover lens, must optically represent at least two, and therefore multiple, functions using light from different light sources that exhibit different colors and / or signal shapes.

[0032] Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawing.

[0033] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0036] The Fig. Figures 1 to 5 are described in a coherent and comprehensive manner. Components that are provided as parts of several embodiments of the light guide device 2, 6, 10, 14, 18 and / or the lighting device 4, 8, 12, 16, 20 are assigned the same reference numerals across all figures.

[0037] Each embodiment of the light guiding device 2, 6, 10, 14, 18 has a first body 22 made of transparent material and a second body 24 made of volume-scattering material.

[0038] From the presentation of Fig. Figures 1 to 5 show that the first body 22, in a longitudinal cross-section shown here, has the shape of a right-angled trapezoid with a first leg 26 and a second leg 28, as well as a first base 30 and a second base 32. The two bases 30 and 32 are arranged parallel to each other. The first leg 26 and the first base 30 intersect at an acute angle of less than 90°, here at an angle of 45°, whereas the first leg 26 and the second base 32 intersect at an obtuse angle greater than 90°, here at an angle of 135°. The second leg 28 intersects each of the two bases 30 and 32 at a right angle of 90°. Furthermore, it is provided here that the first body 22 is perpendicular to the one shown in the Fig. The longitudinal cross-section shown in 1 to 5 has a rectangular transport cross-section through which light flows when it is to be guided or transported through the first body.

[0039] The second body 24 indicates in the based on the Fig. In the embodiments shown in Figures 1 to 5, the longitudinal cross-section has a rectangular shape with a first leg 34 and a second leg 36, as well as a first base 38 and a second base 40. Furthermore, the second body 24 has a shape perpendicular to the shape shown in the Fig. The longitudinal cross-section shown in Figures 1 to 5 forms a rectangular transport cross-section through which light flows when it is to be guided or transported through the second body 24. Furthermore, the first base 30 of the first body 22 and the second leg 36 of the second body 24 abut each other, with the second leg 36 of the second body 24 being completely covered by the first base 30 of the first body 22, whereas the first base 30 of the first body 22 is only partially covered by the second leg 36 of the second body 24. Thus, the two bodies 22 and 24 are arranged directly adjacent to each other and are usually attached to and / or in contact with each other.Furthermore, an intersection point of the first leg 26 and the first base 30 of the first body 22 and an intersection point of the second leg 36 and the second base 40 of the second body 24 are arranged immediately adjacent to each other.

[0040] In addition to the components described above, which are part of all embodiments of the light guide device 2, 6, 10, 14, 16, the second embodiment of the light guide device 6, which is described in Fig.Figure 2 shows a first additional body 42, which is arranged on and / or touches the first leg 26 of the first body 22, and a second additional body 44, which is arranged on and / or touches the second leg 28 of the first body 22. The first additional body 42 has a parallelogram shape in its longitudinal cross-section, and the second additional body 44 has a rectangular shape in its longitudinal cross-section. In one embodiment, each of these additional bodies 42, 44 is unstructured and therefore lacks a regular structure and is thus amorphous. In a further embodiment, each additional body 42, 44 has light-scattering material, at least one optical module, e.g., at least one micro-optical module and / or at least one prism, and / or at least one textured or rough surface.

[0041] In the third, fourth, and fifth embodiments of the light-guiding device 2, 6, 10, 14, 16, an additional body 46 is associated with the first leg 26 of the first body 22. The additional body 46 has a rectangular trapezoidal cross-section, with a gap between the first leg 26 of the first body 22 and the additional body 46. The additional body 46 is designed to align light rays.

[0042] The first embodiment of the lighting device 4 comprises, in addition to the first embodiment of the light guide device 2, a first light source 48, a second light source 50, a reflector 52, and a cover plate 62. The second embodiment of the lighting device 8 comprises, in addition to the second embodiment of the light guide device 6, a first light source 48, a second light source 50, and a reflector 52. The third embodiment of the lighting device 12 comprises, in addition to the third embodiment of the light guide device 10, a first light source 54, a second light source 50, and a reflector 56. The fourth embodiment of the lighting device 16 comprises, in addition to the fourth embodiment of the light guide device 14, a first light source 58 and a second light source 50. Each of the aforementioned light sources 48, 50, 52, 54, 58 comprises at least one light-emitting diode.In contrast, a first light source 60 of the fifth embodiment of the lighting device 20, which also includes the fifth embodiment of the light guide device 18, is designed as a light guide, whereas the second light source 50 of the fifth embodiment of the lighting device 20 has at least one light-emitting diode.

[0043] In the operation of the first embodiment of the lighting device 4 and the light guide device 2, light is emitted from the first light source 48 and projected onto the reflector 52. The light from the first light source 48, reflected by the projector 52, is coupled into the first body 22 via the first leg 26 of the first body 22. Light rays originally emitted by the first light source 48 strike the first leg 26 of the first body 22 at an angle of 45° and are then transported through the first, transparent body 22. Light emitted by the second light source 50 is coupled into the second body 24 via the first leg 34 of the second body 24 and transported through this second, volume-scattering body 24.After passing through the second body 24, light originally to be emitted by the second light source 50 emerges from the second leg 36 of the second body 24 and is coupled into the first body 22 through its first base 30. Inside the first body 22, light originally to be emitted by the first light source 48 is to be mixed and / or superimposed with light originally to be emitted by the second light source 50.

[0044] Within the second body 22, mixed and / or superimposed light from both light sources 48, 50 emerges from the first body 22 through its second leg 28 after passing through it and is to be transported further to the cover disk 62, whereby this mixed or superimposed light passes the cover disk 62 as a common light emission surface.

[0045] In the operation of the second embodiment of the lighting device 8 and thus of the second embodiment of the light guiding device 6, light to be emitted from the first light source 48 is to be projected onto the reflector 52 and from there onto the first additional body 42, which is arranged here on the first leg 26 of the first body 22, wherein light rays that are originally to be emitted from the first light source 48 pass through the first additional body 42 and are then coupled into the first body 22.

[0046] In the second embodiment of the light guide device 6 and / or the lighting device 8, light originally emitted by the second light source 50 is transported through the second embodiment of the light guide device 6 in the same way as in the first embodiment of the lighting device 4 and the light guide device 2. Within the first body 22, light from the first light source 48 is mixed and / or superimposed with light from the second light source 50. After passing through the second body 22, light originally from both light sources 48 and 50 exits the second leg 28 of the first body 22 and is coupled into the second additional body 44. After passing through the second additional body 44, all the light exits the second embodiment of the light guide device 6 and / or the lighting device 8.

[0047] In the third embodiment of the lighting device 12, and thus also in the third embodiment of the light guide device 10, light originating from the second light source 50 is transported through the bodies 24, 22 of the light guide device 10, as in the embodiments described above. Light emitted from the first light source 54 of the third embodiment of the lighting device 12 is first projected onto the reflector 56, reflected from it, and projected at an angle of 90° onto a first leg of the additional body 46. After passing through this additional body 46 and through the air gap between the additional body 46 and the first body 22 of the third embodiment of the light guide device 10, the light originating from the first light source 54 is coupled in through the first leg 26 of the first body 22.Light from the first light source 54 is superimposed within the first body 22 with light from the second light source 50, whereby such superimposed or mixed light from both light sources 50, 54 emerges from the second leg 28 of the first body 22 as a common light emission surface.

[0048] In the operation of the fourth embodiment of the lighting device 16, and thus the fourth embodiment of the light guide device 14, light emitted by the second light source 50 is, as in the embodiments described above, first transported through the first body 24 and then through the second body 22 of the light guide device 14. In this embodiment of the light guide device 14 and the lighting device 16, light from the first light source 58 is projected directly, here at an angle of 90°, onto the additional body 46. After light from the first light source 58 has been coupled into and passed through the additional body 46, this light is also coupled into the first body 22.Light from the first light source 58, which now passes through the first body 22 of the light-guiding device 14, is to be superimposed and / or mixed with light that originally came from the second light source 50. Light thus superimposed and / or mixed emerges from the second leg 28 of the first body 22 as a common light-emitting surface.

[0049] In all the embodiments of the lighting device 4, 8, 12, 16 described above, it is provided that all light sources 48, 50, 54, 58 are designed here as light-emitting diodes or LEDs.

[0050] In contrast, in the fifth embodiment of the lighting device 20, the first light source 60 is designed as a light guide. However, in this fifth embodiment of the lighting device 20, the light emitted by the first light source 60 is to be projected directly onto the additional body 46 at an angle of 90°, just as in the fourth embodiment of the lighting device 16, and furthermore superimposed and / or mixed within the first body 22 with light originally originating from the second light source 50, and transported through the first body 22.
