Description

The invention relates to an elongated light for vehicles, in particular auxiliary brake light, with a light source unit and an optical unit for generating a predetermined light function, wherein the light source unit and the optical unit is disposed in a housing provided with an opening, and with a cover plate, which the opening of the housing closes.

From the WO 2016/087643 A1 is an elongated light for vehicles known, which is designed as additional brake light. It has an elongated, relatively narrow housing in which a light source unit and an optical unit are arranged. The housing is covered on the front by a cover plate. The optical unit comprises a hologram element. Hologram elements can be used to represent three-dimensional objects.

For advertising displays is from the WO 2005/022255 A2 a photosystem with a film lens assembly for generating a three-dimensional image object known. The film lens assembly is formed as a film sheet mounted on a two-dimensional lens plate. The lens plate has a plurality of lens elements distributed in a matrix-like manner, to each of which film segments are assigned to the film surface. On the film segments, the image objects are each captured by exposure. The film surface is firmly connected to the lens surface both during recording and during playback of the image objects. By backlighting this film lens assembly, the image object can be displayed in a spatial representation.

Object of the present invention is to develop an elongated lamp for vehicles such that space-saving a light signature or light function is provided with a spatial appearance, in particular with a depth effect.

To achieve this object, the invention in conjunction with the preamble of patent claim 1, characterized in that the optical unit has a flat film lens assembly for generating a low-light graphic, wherein the film lens assembly on the one hand has a film surface, a plurality of matrix-like and respectively and having a lens array arranged in the main emission direction in front of the film surface, which has a plurality of lens elements arranged in a matrix such that the film segments are exposed in such a way that the depth light graphic projects a number of three-dimensionally in a space in the main emission direction and / or or behind and / or in an extension plane of the film lens assembly arranged first graphic elements and a number of second area graphic elements has to form a background luminous surface, which in the main emission direction behind the film lens anor tion and / or behind the first graphic elements is arranged.

According to the invention, the optical unit has a flat film lens arrangement for generating a deep light graphic. The film-lens arrangement has, on the one hand, a film surface and, on the other hand, a lens arrangement which in each case has film-like segments or lens elements in a matrix-like manner. The film segments of the film surface are each exposed with image objects, so that when the film lens arrangement is backlit by a light source unit, these image objects can be imaged as graphic elements. Advantageously, the invention enables a three-dimensional luminous signature for relatively narrow and elongated signal functions. A depth effect is created by transverse to the longitudinal extent of the light appearing graphic elements, which serve as quasi lighting objects. Alternatively or additionally, a plurality of graphic elements which extend substantially in the extension direction of the luminaire may be arranged offset in the main emission direction of the elongated luminaire or transversely to the luminaire. Since the three-dimensional graphic elements are "stored" in the film surface, differently illuminated film surfaces and the same optical means of the luminaire can produce a different deep light graphic. Advantageously, as a result, depending on the user, different three-dimensional luminous signatures can easily be produced in terms of production technology. The depth effect is generated in particular by the first graphic elements being staggered or continuously imaged in a space in the main emission direction of the luminaire in front of and / or behind and / or in an extension plane of the film lens arrangement as virtually luminous objects. The film segments of the film surface have also been exposed to objects so that second graphics are imaged to form a background phosphor. The second graphic elements extend behind the same and / or behind the film lens arrangement as compared to the at least first graphic element in the main emission direction. The second graphics elements thus enable a large luminous area in comparison to the first graphic elements, which forms a homogeneous luminous base for the resulting deep luminous graphics and thus a correspondingly large luminous area can be generated to ensure the legally prescribed minimum luminous area, for example an auxiliary brake light. Optionally, the background illuminated area may be spatially separated by a plurality of immediately adjacent ones be formed appearing luminous object elements. Advantageously, this can produce a deep-luminescent image with a relatively small overall depth. Since the film lens array is arranged in the main emission direction in front of the light source unit, the light sources are imperceptible to the viewer.

According to a preferred embodiment of the invention, the film-lens arrangement is designed such that by backlighting of the film-lens assembly, the background light surface is produced with a minimum luminous intensity and / or with a minimum luminous area. The minimum luminous intensity or the minimum luminous area corresponds to legal requirements for the corresponding lighting function. For example, the minimum luminous area for an auxiliary brake light is 30 cm ² . By providing the at least one second graphic element, the legal requirements for the light function can thus be met. Due to the at least one first graphic element, a manufacturer-dependent individualization of the light function can take place.

According to a development of the invention, the background luminous surface is contour-shaped to form an edge of the housing. For example, the dimension of the film lens array may be smaller than the dimension of the background phosphor area. Advantageously, the observer is provided with a luminous surface of the luminaire which is larger than the dimension of the light-generating means (film-lens arrangement). Since the background luminescent surface is virtually congruent and of equal size to the contour of the housing of the luminaire, the viewer is given the impression that the entire housing surface or lens of the housing is illuminated.

According to a development of the invention, the background luminous area is perpendicular to the main emission direction of the luminaire. Advantageously, the background luminescent surface is thus arranged oriented to the front side of the luminaire, essentially in the main emission direction.

According to a development of the invention, the contour and / or the dimension of the background luminous area corresponds to a contour and / or dimension of a projection of the housing projecting perpendicular to the main emission direction or of a contour of the cover disk. In this way, a luminous pattern that is homogeneous relative to the main emission direction can advantageously be generated, which corresponds to the size of the opening edge of the housing or the size of the cover disk. It is thus produced a large surface adapted to the housing or the lens homogenous illuminated surface.

According to a development of the invention, housing walls of the housing are provided on the inside with a diffusely reflecting surface. Advantageously, this can be achieved that the light function is not disturbed by stray light of the optical unit in an undesirable manner. In particular, this counteracts spot formation (bright reflection points) on the inside of the housing wall. For example, the inside of the housing walls may be formed in a mirrored manner with a structured optical surface which is produced by erosion, etching, lasers or the like.

According to a development of the invention, the film-lens arrangement is designed such that the depth light graphic produced thereby has a plurality of identical and / or unequal first graphic elements distributed in the longitudinal extension of the luminaire, wherein the first graphic elements are each rod-shaped and / or elongated and parallel or under one different acute attitude angle to the main emission direction. Advantageously, a spatiality of the deep light graphic can thereby be generated in a simple manner, although the luminaire is designed to be relatively narrow. By way of example, the first graphic elements can be designed as lightbars whose longitudinal axes converge in an area behind the background luminous area. Additionally or alternatively, the lightbars can also be arranged offset in parallel, preferably extending in the main emission direction.

According to a development of the invention, the film lens arrangement can be designed such that the deep light graphic has a number of extending in the longitudinal extent of the lamp first graphics elements. These may, for example, be arranged vertically and / or laterally offset transversely to the main emission direction, so that a spatiality of the deep light image is thereby produced by simple means.

According to a development of the invention, primary light elements are respectively assigned to the light sources of the light source unit, so that the light emitted by the light sources is parallelized and strikes the same substantially perpendicular to the plane of extent of the film lens arrangement. This ensures a homogeneous backlighting of the film lens arrangement.

According to a development of the invention, the light sources are designed such that they emit light in white light color and / or red light color and / or yellow light color. Advantageously, different light functions, such as daytime running lights, cornering lights, brake lights, etc., can thus be generated.
