Description

The present invention relates to a signal light for a vehicle and a vehicle with the signal light.

Known vehicles, especially motor vehicles, usually contain front, rear and side lights (generally: vehicle lights). The vehicle lights include, among other things, signal lights that are intended to emit predetermined signals, each of which is representative of a current or future event specific to one's own vehicle. Typical signal lights in well-known vehicles are, for example, direction indicators (colloquially turn signals), brake lights or reversing lights.

A signal light known from the prior art is in the document DE 10 2004 028 970 A1 disclosed. The luminaire essentially consists of a light-guiding element, a light source and a coating. The light-guiding element has a light exit surface on its front side arranged in the radiation direction and a reflection surface on its back side. Light coupled into the light-guiding element via a light coupling surface is passed on in the light-guiding element by means of total reflection, with light striking the reflection surface being deflected towards the light exit surface and emerging from it in the emission direction.

Against this background, it is an object of the present invention to provide a signal light for a vehicle that can be produced relatively easily and cost-effectively and with which a light signal can be emitted with high luminous efficiency and precisely into a relatively wide spatial area in the vicinity of the signal light. It is also a task to provide a corresponding vehicle.

This task is achieved by a signal light with the features of patent claim 1 and a vehicle with the features of patent claim 10. The dependent claims represent preferred embodiments.

The signal light is intended for a vehicle, preferably a motor vehicle (in particular a land vehicle, water vehicle or aircraft), and comprises collecting optics for collecting light from a light source device, a lens for distributing the light and a light guide extending from the Collecting optics extends in the direction of the lens and has a decoupling section at its end opposite the collecting optics. The collecting optics are arranged to direct at least a first part of the light onto the lens in such a way that the first part of the light spreads between the collecting optics and the lens outside the light guide and strikes the lens in a first angle of incidence range. The light guide is designed to guide a second part of the light coupled into the light guide from the light source device in the direction of the lens. The decoupling section is arranged to decouple the second part of the light from the light guide in such a way that the second part of the light impinges on the lens in a second angle of incidence range, which is at least partially outside the first angle of incidence range. To generate the light, the light source device preferably contains at least one light source (i.e., one or more light sources), which (each) can be designed as a so-called point light source and can emit diverging light in the direction of the collecting optics.

The present signal light can be produced comparatively easily and inexpensively using one or more casting processes to form the collecting optics, the lens and/or the light guide. Advantageously, the optical components required for the signal light, in particular the lens and the collecting optics, can be manufactured relatively easily and in large quantities. In addition, the light can be emitted in additional directions and thus at a wide angle, so that the vehicle or the signal from the signal light is clearly visible from many different directions. This increases the safety of the vehicle. In the signal light proposed here, the light guide makes it possible to guide the second part of the light comparatively easily and flexibly and specifically into desired environmental areas.

Preferably, the aforementioned (specific) light source of the light source device is set up to emit the first part and the second part of the light. This light source and any other light sources of the light source device are/are preferably each designed as a light-emitting diode, in particular a light-emitting diode or laser diode. Each of these light sources can be separately electronically controllable and/or have partial light sources that can be set up to emit light with different light parameters (for example different light spectrums, colors and/or light intensities). In particular, each of the light sources can be mounted on a support element (for example a circuit board) and connected to a control device in a signal-transmitting manner. A main radiation direction of the respective light source can define an optical axis along which the light from the light source can propagate. If several light sources are provided, they can preferably be used in parallel lel be aligned with each other. What is said below for the light source can apply accordingly to all other light sources of the light source device.

The optical axis can run through the light source and/or in a straight line from the light source through the collecting optics, the lens and/or optionally an additional cover lens (also called external lens). Along the optical axis, or in a main direction of propagation of the light immediately before it hits the collecting optics, the light source, the collecting optics, the lens and, if necessary, the additional cover disk are spaced apart from one another.

According to its general definition, the term optics refers here to a device that influences the propagation of light. Accordingly, the function of the collecting optics is preferably to refract the divergent light (more precisely, the divergent beam of light) from the light source such that it is less divergent. Preferably, the collecting optics is set up to collimate the first part of the light and optionally the second part of the light (substantially) in one or two mutually perpendicular directions. Essentially this means that the condition of the geometric optics for collimation (position of the (point) light source in the focus of the collecting optics) is met, apart from minor manufacturing tolerances. An angle between two edge rays of the collimated light can be less than 5°. When the light from the point light source is collimated in one direction, there is a plane in which the light rays of the beam are collimated. When collimating in both directions, all rays actually run parallel to each other. These collimation functions can be implemented comparatively easily and precisely if the collecting optics are designed as a disk, in particular as a collecting lens disk or as a Fresnel disk.

Preferably, the collecting optics for collecting and directing have one or more convex collecting lenses or Fresnel lenses, which can be formed on a first surface of the collecting optics opposite the lens or (preferably) on a second surface of the collecting optics facing the lens. Each of these lenses can be arranged coaxially to a light source of the light source device. In a particularly preferred embodiment, the first surface of the collecting optics opposite the lens has a lower refractive power than the second surface of the collecting optics facing the lens. Preferably, the first surface is planar and the second surface is convex, so that the collecting optics can be referred to as plano-convex. In this way, as explained in more detail below, it can be efficiently realized that the second part of the light remains divergent when it propagates from the collecting optics into the light guide. Furthermore, it is conceivable that the second part of the light enters the collecting optics through a region of the first surface which (only) does not refract the second part of the light or refracts it to a lesser extent (in particular not collimated) than another region of the first surface collimates the first part of the light.

Directing the first part of the light may consist of maintaining the main direction of propagation of the first part of the light so that the optical axis runs straight through the collecting optics. The first and second parts of the light can strike the first surface of the collecting optics as a common beam of rays and spread out in the material of the collecting optics. For this purpose, the collecting optics are advantageously transparent (clear or colored), particularly in the area of the beam path of the first and second parts. The second surface of the collecting optics forms a light exit surface through which only the first part of the light can escape into the immediate surroundings of the collecting optics (without getting into the light guide). Between the second surface of the collecting optics and a first surface of the lens facing the collecting optics, the first part of the light is preferably at least partially collimated, as described above.

The second part of the light, on the other hand, preferably propagates from the collecting optics directly (i.e. directly) into the light guide, without overcoming a phase boundary or a jump in refractive index. In order to be able to provide this function in a cost- and light-efficient manner, the light guide can be molded onto the collecting optics. Most preferably, the light guide is designed in one piece and without joints (thus cohesively) with the collecting optics. The light guide and the collecting optics can be produced together as an integral casting, in particular a plastic casting. The light guide and/or the collecting optics can be made, for example, from polymethyl methacrylate (PMMA) or polycarbonate (PC).

In particular, the light guide and the collecting optics can be designed together as an angled body with an L-shaped cross section. An interior angle of this body can be at least 30° or at least 45° or at least 60°. The interior angle can also be at most 150° or at most 135° or at most 120°. In a preferred variant, the light guide tapers as the distance from the collecting optics increases in order to increase the illuminance in the second part to increase light. The light guide can also be transparent (clear / colored) and made of the same material as the collecting optics. If the light guide is clear and transparent, it may not be visible from the outside from a certain distance when the light source device is deactivated.

The light guide is preferably designed as a surface light guide. In the present case, a surface light guide (also: flat light guide) can be referred to as a light guide which extends further in two mutually orthogonal directions (longitudinal direction/length and height) than in a direction perpendicular to the two orthogonal directions mentioned. Here, the light guide can be designed to guide the light coupled into it two-dimensionally in its longitudinal direction and its height (in particular under total reflection).

With its first light-guiding surface, the light guide preferably delimits a spatial area inside the signal light, which is preferably also delimited by the collecting optics and the lens and through which the first part of the light can spread. A second light-guiding surface of the light guide is preferably formed on a side of the light guide opposite the spatial region. Between these light-guiding surfaces, the second part of the light is preferably guided with reflection (in particular total reflection) on the light-guiding surfaces. If the second part of the light is introduced divergently into the light guide, it can preferably remain divergent in the light guide and after decoupling at the decoupling section. This allows the second light to be directed more easily into the environment over a larger angular range. A central main surface of the light guide (central longitudinal plane) can run transversely, in particular perpendicularly, to a main surface of the collecting optics, to a focal plane of the collecting optics and/or transversely to a light exit surface of the light guide.

Preferably, an inner edge at a boundary between the collecting optics (collecting optics disk) and the light guide defines a boundary between the first part of the light and the second part of the light. At the inner edge, the light is preferably separated into the first part and the second part. That is, up to this inner edge, the first part of the light and the second part of the light can propagate together in a single light bundle along the optical axis. After the division by means of the inner edge, the further propagation of the second part of the light can take place independently of the propagation of the first part of the light through the spatial area. Between the inner edge and the light guide, the main direction of propagation of the second part of the light can run parallel to the optical axis. The inner edge can be present where the above-mentioned interior angle has the values mentioned.

It has been said that the lens is intended to distribute the light (including the first and second parts). The light can be distributed in a refractive (diffusing) or light-scattering (diffuse) manner. In the second case, the lens can be designed as a lens (so-called diffuser), at least in the section in which the light propagates through the lens. In the former case, the lens can have at least one lens, which can be set up to refract the first part and/or the second part of the light in such a way that it (or the associated bundle of rays) is more divergent after propagation through the lens than before Hitting the lens. The lens can be plano-convex or biconvex. At least on a second surface of the light guide opposite the collecting optics, the lens can be convexly curved. In a further variant, the at least one lens can be designed as a plano-concave or biconcave diverging lens.

The decoupling section is preferably set up to decouple the second part of the light in such a way that the second part of the light propagates at least partially through the at least one lens. As a result, the at least one lens can be arranged to scatter (at least refractively) both the first part of the light and the second part of the light. This synergistically enables a compact design while at the same time allowing the light to be emitted from a wide angle.

For this purpose, it is advantageous that the second angle of incidence range extends beyond the first angle of incidence range. The angle of incidence range can be referred to as the (quantitative/absolute) range of values under which the (in each case entire) first or second part on the first surface of the lens hits the lens relative to the surface normal there (so-called perpendicular of incidence). Most preferably, the second angle of incidence range may be adjacent to the first angle of incidence range or lie completely outside the first angle of incidence range. The first angle of incidence range can be from 0° to 45° or 0° to 30° or 0° and 15°. The second angle of incidence range may be from more than 75° to 90°, more than 60° to 90°, more than 45° to 90°, or more than 30° to 90°, or more than 15° to 90°.

In order to decouple the second light from the light guide so that it is incident on the lens in the second angle of incidence range, the light guide can have an end surface on the decoupling section, preferably facing away from the collecting optics have, which runs at an angle to the main surface of the light guide and / or to at least one light guide surface of the light guide. The end surface preferably runs transversely to the main surface of the light guide and to the light guide surfaces in such a way that they totally reflect the second part of the light and thereby allow the second part of the light to fall more steeply onto the first light guide surface (than required for total reflection), so that the first light guide surface for this The second part of the light reflected at the end surface is (at least partially) translucent. Therefore, a first end of the end surface is preferably located on a side of the light guide facing the spatial region, closer to the lens than a second end of the end surface is located on a side of the light guide facing away from the spatial region. The decoupling section is therefore preferably designed to be essentially wedge-shaped. The end surface can also be mirrored or as an alternative to the total reflection there. The end surface can also rest against the lens. After the first and second part of the light has spread through the lens, the first and/or second part of the light can leave the signal light through an additional cover plate and spread further into the area around the signal light.

In a further variant, the second part of the light can emerge at least partially through this end surface reflectively as described above and/or at least partially through refraction at the end surface. In this case, the end surface is preferably designed such that the refracted second part of the light strikes the lens in the second angle of incidence range.

Corresponding to the first and second incidence angle ranges, a second reflection angle range in which the second part of the light emerges from the lens can lie outside a first reflection angle range in which the first part of the light emerges from the lens. To put it simply, the signal light allows the second part of the light to be at least partially emitted into a solid angle into which essentially no (unscattered) light from the first part of the light reaches. The first failure angle range can (relative to the failure slot) be between 0° and 60° or between 0° and 50° or between 0° and 45°, for example. The second reflection angle range can be between 60° and 90° or between 65° and 85°.

The end surface mentioned can preferably be flat. In a further variant, however, it is provided that the end surface is convex. The end surface can have a plurality of flat first partial surfaces which adjoin one another and/or are aligned (facet-like) at an angle to one another. The angle between adjacent first partial surfaces can be, for example, between 0° and 30° or 0° and 20°. The first partial surfaces can also be aligned at different angles relative to the main surface of the collecting optics or the main surface of the lens. This allows the signal lamp to diffuse (distribute) the second part of the light in mutually perpendicular directions if the lens is provided with cylindrical lenses whose focal lines are perpendicular to the main direction of propagation of the second part of the light in the light guide.

In order to further improve this dispersion, in a further variant the end surface can have a plurality of second partial surfaces which are curved outwards with respect to the light guide, preferably cylindrical (simple). The second partial areas de facto form cylindrical reflectors. Their focal lines preferably run parallel to one another and/or perpendicular to focal lines of cylindrical lenses of the collecting optics.

The vehicle proposed here is provided with at least one signal light described in detail above. The vehicle can preferably be a motor vehicle (in particular a passenger car, most preferably an electric vehicle). Preferably, the light guide is aligned parallel to the vehicle's longitudinal axis and/or is arranged closer to the vehicle's longitudinal axis than the collecting optics. In particular, it can be provided that a main direction of extension of the light guide runs parallel to the longitudinal axis of the vehicle. Most preferably, the signal light is aligned such that the decoupling section decouples the second part of the light in the direction of a longitudinal side of the vehicle. The signal light can be, for example, a brake light, a direction indicator, a daytime running light, a position light or a reversing light.

The 1 and 2 show a signal light 10 for a vehicle 100, which in the present case is a motor vehicle in the form of a passenger car (see 5 ). The signal light 10 is designed, for example, as a direction indicator or as a brake light and contains a light source device 20, a collecting optics 30, a lens 40 and a light guide 50. The view from 2 corresponds to a (cross) section along plane 1 1 .

The light source device 20 has several light sources that are separate from one another, which in the present case are designed as light-emitting diodes and are mounted on a carrier element 23 (circuit board). A distinction is made below between the light source 21 and the further light sources 25, the light guide 50 being arranged in such a way that part of the light from the light source 21, but no light from the further light sources 25, is coupled into the light guide 50. In a modification, several light sources 21 are provided, which are arranged one above the other (vertically) in the installed position of the signal light 10 on the vehicle 100 and can preferably shine into the light guide 50 or each into at least one of several light guides 50. The beam path of the light from the other light sources 25 is in 2 For the sake of clarity, only partially shown. It goes without saying that this light also propagates through the collecting optics 30, the lens 40 and the additional cover disk 70. For the light from the further light sources 25, what has been said applies accordingly to the first part 24 of the light from the light source 21 (cf. beam paths in 2 ).

Since the light source 21 is practically designed as a point light source, which is defined by the fact that it has a small spatial extent in relation to its distance from the illuminated object or from the viewer, the beam path of the light emitted by it diverges along an optical axis X. This light contains a first part 24, which propagates between the collecting optics 30 and the lens 40 along and outside the light guide 50, and a second part 26, which is coupled into the light guide 50 by means of the collecting optics 30.

The collecting optics 30 serves to collect the light (reducing the divergence in at least one direction) and in the present case is designed, for example, as a collecting lens disk with a grid of (here plano-convex) Fresnel lenses, each of which is one of the light sources 21 or one of the others Light sources 25 are assigned. Columns in which the Fresnel lenses are arranged are in 1 indicated by lines. At a distance from the light guide 50 (see 1 top left), the collecting optics 30 can optionally have an additional arrangement of rollers that horizontally distribute/scatter light from the light source device 20 in the installed position of the signal light 10 on the vehicle 100.

In particular, the collecting optics 30 is set up to partially or completely collimate the first part 24 of the light so that when viewed in the in 2 shown, containing the optical axis X on a second side of the collecting optics 30 opposite the light source device 20 does not diverge. In contrast, the second part 26 of the light is left divergent by the collecting optics 30, so that after propagation through the collecting optics 30 it diverges both in the plane mentioned and perpendicular to it. If the collecting optics 30 is designed in a modification of this variant with an arrangement of cylindrical lenses, the focal lines preferably run in 2 perpendicular to the plane of the sheet, so that what was said above regarding collimation applies accordingly.

The collecting optics 30 is arranged to direct at least the first part 24 of the light onto the lens 40 in such a way that the first part 24 of the light spreads between the collecting optics 30 and the lens 40 outside the light guide 50 and in a first angle of incidence range A1 the lens 40 hits. Here, the first part 24 of the light spreads through a spatial area that is delimited by the lens 40, the collecting optics 30 and the light guide 50. A medium in the spatial region has a refractive index that is lower than the refractive index of the light guide 50. Preferably the spatial region is filled with air. The angle of incidence range A1 extends from 0° to 30° (against the perpendicular of incidence), so that the entire first part 24 of the light is incident on the lens 40 distributing the light in this angle of incidence range A1.

The light guide 50 is designed as a surface light guide, extends from the collecting optics 30 in the direction of the lens 40 and has a decoupling section 54 at its end opposite the collecting optics 30. The light guide 50 is together with the collecting optics 30 as an integral, joint-free (monolithic; “out “One cast” component is formed. The second part 24 of the light thus passes through the collecting optics 30 into the light guide 50, without a refractive index jump between the collecting optics and the light guide 50 have to be overcome.

A boundary between the first part 24 of the light and the second part 26 of the light is defined by an inner edge 32 between the collecting optics 30 and the light guide 50.

The light guide 50 is then set up to guide the second part 26 of the light coupled into the light guide 50 from the light source device 20 in the direction of the lens 40. For this purpose, the light guide 50 and the collecting optics 30 run transversely (essentially perpendicular) to one another. In a main direction of propagation of the second part 26 of the light through the light guide 50, this second part 26 spreads between two opposing light guide surfaces of the light guide in the direction of the coupling-out section 54; The light guide 50 preferably tapers in this direction, as shown in 1 shown.

The decoupling section 54 is arranged to decouple the second part 26 of the light from the light guide 50 in such a way that the second part 26 of the light (in particular completely) impinges on the lens 40 in a second angle of incidence range A2, which is at least partially outside the first angle of incidence range A1 lies. For this decoupling, an end surface 58 on the decoupling section 54, which is arranged at an end of the light guide 50 opposite the collecting optics 30, runs at an angle to the main surface H of the light guide 50 and/or to at least one light guide surface of the light guide 50.

The end surface 58 is aligned to reduce an angle of incidence of light rays of the second part 26 of the light onto the media boundary between the light guide 50 and the said spatial region (relative to the perpendicular of incidence) beyond the critical angle for total reflection. The second part 26 of the light is deflected reflectively out of the light guide 50. In a modification, the second part 26 of the light can emerge at least partially reflectively as described above and/or at least partially by refraction at the end surface 58 through this end surface 58 in order to impinge on the lens 40 in the second angle of incidence range A2. The second incidence angle range A2 extends (relative to the incidence perpendicular) from 30° to 90°, preferably from 30° to 70°. The upper limit of this second angle of incidence range A2 can correspond to the critical angle of the total reflection on the first surface of the lens 40 facing the collecting optics 30.

In the variant from the 1 and 2 the light source 21 is assigned to one of several lenses of the lens 40 in such a way that both the first part 24 of the light and the second part 26 of the light propagate through the one lens in order to reach the surroundings of the lens via a light exit surface of the lens 40 40 to get there. If the optional additional cover plate 70 is provided, the first part 24 of the light and the second part 26 of the light can also spread through the cover plate 70 into the surroundings of the signal light 10. The one lens mentioned thus advantageously serves to refract the first part 24 and the second part 26 of the light. As in 2 shown, an angle a1 between an edge ray 29 of the first part 24 of the light beyond the lens 40 and the light exit surface of the lens 40 is greater than (for example at least twice as large as) an angle a2 between an edge ray 27 of the second part 26 of the light beyond the lens 40 and the light exit surface of the lens 40.

One in 3 The further signal light 10 shown differs from the signal light 10 1 that its end surface 58 is convex and/or has a plurality of planar first partial surfaces 60 which adjoin one another and run at an angle relative to one another. In this embodiment, the decoupling section 54 is thus provided with several facets 60 defined by the first partial surfaces 60. In this variant too, the second part 26 of the light can be guided partially or completely by reflection at the end surface 58 and/or partially or completely by refraction of light at the end surface 58 in such a way that it strikes the lens 40 in the second angle of incidence range A2. The facets serve to direct the light in a direction perpendicular to plane 1 (perpendicular to a cross-sectional plane of collecting optics 30 and lens 40; cf. 1 ) to distribute. In addition, the signal light 10 indicates 3 all features of the signal light 10 off 1 on.

Another signal light 10 off 4 This differs from the signal light 10 1 that signal light 10 is off 4 the end surface 58 has a plurality of second partial surfaces 62 which are cylindrically curved outwards with respect to the light guide 50. Cylindrical axes of the cylindrical second partial surfaces 62 run parallel to one another and form a main plane of the end surface 58. In this variant, the second partial surfaces 62 serve to direct the light in a direction perpendicular to plane 1 (perpendicular to the cross-sectional plane of collecting optics 30 and lens 40). to distribute. In addition, the signal light 10 indicates 4 all features of the signal light 10 off 1 on.

At the in 5 In the vehicle 100 shown, two signal lights 10 are provided, each according to one of the 1 , 3 and 4 can be designed. Preferably, a signal light 10 on a front of the vehicle 100 is designed as a direction indicator (turn signal) and another signal light 10 on a rear of the vehicle 100 is designed as a direction indicator, alternatively as a brake light. In both of these signal lights, the light guide 50 is preferably aligned parallel to the vehicle's longitudinal axis L and/or is arranged closer to the vehicle's longitudinal axis L than the collecting optics 30.
