Definitions
- the invention relates to a lighting device for a motor vehicle headlight, comprising:
- a primary optics element which is assigned to the illuminant, the primary optics element having a primary light entry surface for receiving light emitted by the illuminant, the primary optics element being designed to guide the light to a primary light exit surface of the primary optics element and through the primary -To emit light exit surface in a main emission direction;
- a secondary optics element which is arranged in the direction of light propagation after the primary optics element and is spaced from the primary optics element, wherein the secondary optics element has a secondary light entry surface, the secondary light entry surface and the primary light exit surface are arranged to each other in such a way that the light of the lamp from the primary -Light exit surface is radiated into the secondary optical element via the secondary light entrance surface, the light within the secondary optical element being guided to a secondary light exit surface of the secondary optical element, at least the secondary light entrance surface and / or the secondary light exit surface being uneven, in particular curved, where the secondary optics element has a spatial extension of at least 2 mm, preferably more than 15 mm, in the direction of light propagation between the secondary light entry surface and the secondary light exit surface.
- the invention also relates to a motor vehicle headlight with a lighting device.
- the object of the present invention is to alleviate or eliminate the disadvantages of the prior art.
- the invention therefore sets itself the goal in particular of creating a lighting device in which the light emission is improved.
- the secondary light entry surface is formed by a large number of two-dimensionally adjacent optical elements which are designed to refract the light rays as they enter the secondary optics element in such a way that the light rays, after they have been refracted when they exit the secondary light exit surface, into Direction of the main emission are oriented.
- the light beams are thus advantageously oriented upstream and downstream of the secondary optical element in or parallel to the direction of light propagation. The refraction of the light rays when entering the secondary optics element via the secondary light entry surface by the optical elements can thus compensate for the refraction at the secondary light exit surface.
- Each optical element on the secondary light entry surface can be designed as a facet, which together are preferably arranged in a uniform grid on the secondary light entry surface.
- a facet is to be understood as a smaller geometric arrangement on the secondary light entry face than the secondary light entry face, such as, for example, a surface element tilted relative to the secondary light entry face.
- the individual facets are preferably of the same type.
- the refraction of light on a facet is essentially predetermined by the curvature of the secondary light exit surface or the light refraction on the secondary light exit surface caused by it, since the light refraction on the facet compensates for the light refraction on the secondary light exit surface.
- the facets can each be oriented at an angle g 0 ° to the secondary light entry surface.
- the angle g is determined by the curvature or the angle of refraction at the secondary light exit surface.
- the angle g can also be zero.
- the distance between the primary optics element and the secondary optics element can be 1 mm, preferably 2 mm. This has the advantage that the optical elements on the secondary light entry surface cannot be damaged by possible contact with the primary light exit surface.
- the primary optics element and the secondary optics element can be formed in one piece or in one piece.
- the primary light exit surface can have light-scattering means in order to scatter the light radiated in by the illuminant around the main emission direction when it exits the primary light exit surface. This results in the advantage that the secondary light exit area is illuminated with an essentially constant illuminance per unit area.
- the secondary optics element is preferably designed as a transparent solid body.
- the secondary optics element can be made of plastic, for example.
- the secondary optics element can also be designed as a transparent hollow body.
- the primary optics element is preferably designed as a transparent solid body.
- the primary optics element can be made of plastic, for example.
- the primary optics element can also be designed as a transparent hollow body.
- the secondary light entry surface and the secondary light exit surface can be curved, with an essentially constant normal distance between the secondary light entry surface and the secondary light exit surface, starting from the secondary light exit surface.
- the curvature can come about because the secondary optics element has an arrow, whereby the curved design allows the desired refraction of light to occur on the secondary light exit surface, which is compensated in particular by the optical elements on the secondary light entrance surface.
- the normal distance between the secondary light entry surface and the secondary light exit surface can also not be constant, with the secondary The light entry surface and the secondary light exit surface can have a different curvature.
- the primary optics element can have a single primary light entry surface
- the lighting means can comprise a light source carrier, preferably a printed circuit board, and a number of, in particular individually controllable, light sources arranged thereon, the light source carrier preferably being arranged on the primary light input surface in such a way that the Light from the light sources is introduced into the primary optics element exclusively via a primary light entry surface. This advantageously results in minimal losses when light is irradiated into the primary optics element. Due to the individually controllable light sources, certain light patterns can be generated on the secondary light exit surface.
- the light sources can be arranged on the light source carrier along a substantially ring-shaped light source path, the light source path being composed of a string of the shortest distances between two adjacent light sources, the light sources being distributed in particular at even distances over the entire light source path .
- the secondary optics element can have a recess which is such that the secondary light exit surface has the shape of a closed trajectory.
- the light source path can depict the geometric shape of the closed trajectory. This has the advantage that the individually controllable light sources, which are arranged along the light source path, can create light images or lighting functions that can be mapped via the closed trajectory of the secondary light exit surface that corresponds to the light source path.
- the illuminant can be arranged in relation to the primary light entry surface in such a way that the light is radiated from the illuminant into the primary optics element in a direction deviating from the main emission direction, preferably orthogonal to the main emission direction, deflection means preferably being arranged and set up within the primary optic element in such a way that the light after entering the primary optics element within the primary optics element through the Deflecting means in the direction of the main emission direction.
- the size, in particular the longitudinal extent, of the lighting device can be reduced, which in turn reduces the installation space required, for example in a motor vehicle headlight.
- a screen can be arranged between the primary optics element and the secondary optics element. This has the advantage that scattered light, which can be emitted to the side of the secondary light entry surface, is blocked. As a result, the homogeneity of the light intensity emitted via the secondary light exit surface can be improved.
- a motor vehicle headlight with a lighting device according to the invention can be provided.
- the terms “up”, “down”, “horizontal”, “vertical” are to be understood as indicating the orientation when the lighting device is arranged in the normal position of use after it has been installed in a motor vehicle headlight, for example.
