Description

LIGHTING ELEMENT

TECHNICAL AREA

The invention relates to an ambient lighting with a lighting element for arrangement in one

Innenausstat ungsteil a vehicle to both a direct and at the same time an indirect illumination of the

Vehicle interior to realize.

STATE OF THE ART

A variety of systems are known from the prior art, which can be integrated in vehicle interior trim parts and can be used either to display an indirect or a direct illumination of the vehicle interior as so-called ambient lighting.

By way of example, reference is made here to the patent EP 988 179 Bl. The published in this patent

Sunlight ladder is used as suture material

Interior parts of motor vehicles used, wherein the Lichtwellenieiter emits light over a portion of its length and thus illumination of the

Vehicle interior causes. The light is directly perceived by a Pahrzeuginsassen and the

Design options for lighting effects are limited to those achievable with the Lichtwellenieiter

Mold treasure,

An alternative solution shows the German

Offenlegungsschrif DE 10 2008 054 563 Äl. This discloses a so-called reflector rail, which can be connected to one or more decorative materials. About first openings light can enter, which is reflected within the reflector rail and via second openings of the

Reflector rail is decoupled again. The reflector rail is designed so that lighting effects on the visible side of the decorative materials can be realized. Since the materials used in vehicle interiors usually reflect light to a certain extent, the vehicle occupant perceives the light coupled out via the reflector rail indirectly after reflection on the decorative layer.

The disadvantage of this solution is that one in the

Realization of light effects by the properties of the reflector rail _. , as well as the decorative materials is limited.

SUMMARY OF THE INVENTION

An object of the invention is a

Lighting element for an ambient lighting for a

Vehicle, preferably a Kraftfah stuff to provide, with both a direct, and at the same time an indirect ambient lighting can be realized, the direct and the indirect ambient lighting are possible independently designed.

For this purpose, the inventive

Lighting element at least one light extraction element and a reflection element. Light-outcoupling elements are variously known to those skilled in the art

Variants known. The light-outcoupling element is designed such that light is radiated substantially in the direction of the vehicle interior and can be perceived directly by the vehicle occupant.

In addition to the light emitted in the direction of the vehicle interior, a part of the light of the

Lichtauskopplungselemente radiated substantially parallel to or in the direction of the vehicle interior facing the visible side of the interior trim part of the vehicle.

According to the invention is laterally next to the

Lichtauskopplungselement a reflection element arranged, with which this part of the light in turn, in the direction of

Vehicle interior can be deflected, creating a special light effect is achieved and usually from the Re lektionsgrad of the decorative layer on the

Interior decor part provided decorative material dependent indirect ambient lighting now arranged by the invention laterally next to the light extraction element

Reflection element can be designed specifically.

By the phrase _" beside the side

Lichtauskopplungselement angeordnete, is to be understood according to the invention that the reflection element is arranged next to the light outcoupling element, that radiated from this substantially parallel to or in the direction of the decorative layer of the interior trim part of the vehicle radiated light to a perceptible extent by the reflection element in the direction of the vehicle interior , B, should that

Ref less lectionelement be arranged within the directly or indirectly spanned by the light extraction element, perceptible light cone.

The reflection element can be formed from plastic, metal or other suitable materials.

If the reflection element is formed of a plastic, preferably a transparent plastic, the

Lichtauskopplungselement integrally formed and made of the same material with the reflection element and are produced, for example in an extrusion or

Injection molding.

In an embodiment of the reflection element made of metal, the reflection surfaces are preferred for increasing the

Reflectance post-processed, for example, at least partially polished, coated or otherwise structured.

The light extraction element can be made of a transparent or translucent plastic, for example as

Extruded or injection molded component may be formed, in which a light coupling of a light source takes place. The

Light-outcoupling element may be structures or coatings having a light extraction in the direction of

Favor vehicle interior,

Alternatively, the light coupling via several at

Lichtauskopplungselement arranged light sources, such as single or multi-color LEDs (eg B. RGB LED) take place. In a further alternative embodiment variant, the light-outcoupling element itself is designed as a light source, for example as a single-color or multi-color LED, OLID or as an electroluminescent component,

The light-outcoupling element can have almost any two- or three-dimensional geometry.

In a preferred embodiment, that is

Lichtauskopplungselement linear designed. In this case, the reflection element is preferably substantially parallel to the line-shaped light extraction element

arranged. By substantially parallel, it is understood here that the longitudinal extension of the

Light outcoupling element and the reflection element are arranged substantially parallel. In this case, both the light-outcoupling element and the reflection element may have an internal structure which may vary around the longitudinal extension, and may consist, for example, of a serpentine or zigzag-shaped course, an interrupted extension, a juxtaposition of symbols and the like.

Under essentially parallel should also

be understood that the reflection element is parallel to an outer edge of the light extraction element or approaches or removes at a small angle to the direction of an outer edge of the light extraction element.

It is preferred that the light-outcoupling element on, within or in the edge region adjacent to a

Decorative layer is arranged. The decorative layer may be a layer of any material commonly used in the vehicle interior, or a combination of these materials. For example, here are leather or

Artificial leather layers, fiber layers and textiles of synthetic or natural fibers, as well as

Plastic layers, such as films (transparent, translucent, colored) or mentioned metal or metallized layers. Of course there are also any

Combinations of the aforementioned materials or layers and other unspecified suitable materials as

Decorative layer in question.

In a preferred embodiment variant, a light manipulation element is provided in the beam path between the light coupled out by the light-outcoupling element and the reflection element. The light manipulation element is designed such that the direction, the amount and / or the

Properties of the light manipulation element

Incoming light are changed by this, before the light impinges on the Refiexionselement.

The light manipulation element can be designed, for example, as an optical filter, the color, the

Wavelength, polarization or direction of the

influencing incident light rays. The

Light manipulating element may be of any suitable type

Material and have a structure with regard to the desired manipulation or morphology. For example, the light manipulation element

Have openings through which the incident

Light rays are directed in their direction,

for example, to one or more reflection elements e, or by which the amount of light conducted in the direction of the reflection element is reduced. By way of example only, porous materials such as open-cell foam structures of metals, glasses or plastics and fiber structures of artificial or natural fibers may be present at this location

mentioned. The aforementioned open-line. structures with transparent or translucent materials, like

For example, polymers may be at least partially filled,

Alternatively, the light manipulation element may be a body made of a transparent or translucent material, which may include arbitrarily shaped moldings or molded parts arranged within the material

having light-influencing properties. The shaped bodies or molded parts can be reflective, for example,

light-absorbing or else translucent but be designed in a different color compared to the surrounding material. The shaped bodies or shaped parts can be structures designed in a previous step, which are subsequently connected to the transparent or

be surrounded by translucent material, or a kind of bulk material, that before the final formation of the

Lichtmanipulationselements the transparent or

translucent material is added to a certain extent.

In a preferred variant that is

Lichtmanipulationselement of the same material as the decorative layer. In a particularly preferred

Embodiment variant, a portion of the decorative layer is designed as Lichtmanipulationselement, for example, by a projecting into the vehicle interior seam stub or an edge region of a decorative layer of a porous

Fiber composite material or a compression or embossing of the decorative layer through the subregions of the decorative layer in the beam path between the light outcoupling element and

Reflecting element to be positioned.

In a particularly preferred embodiment, this is

Light manipulation element immediately on

Light-outcoupling element arranged or executed integrally therewith. In this case, the light manipulation element may have light-scattering or light-reflecting particles or structures. For example, glass (hollow) balls or Foam structures (for example metal foams) or indentations or bulges in or on

Be arranged light extraction element, which is an increased emission of light parallel to or in the direction of

Decorative layer of the interior trim part of the vehicle effect or the direct emission of light

reduce and at the same time cause interesting light effects.

In an alternative embodiment, this is

Light manipulation element disposed directly on the reflection element or executed integrally therewith.

The light extraction element, the reflection element or the light manipulation element are preferably within or in the edge region adjacent to a decorative layer of the

Interior parts provided. For this purpose, the

Decorative layer have a recess or recess in which the respective element is arranged. Alternatively, however, the element can also be arranged in the edge region of a subregion of the decorative layer (such as, for example, between two blanks which are joined together to form the decorative layer) or directly onto the surface

Decorative layer applied, for example, printed (eg, 3D printing), be.

In a preferred embodiment this protrudes

Light extraction element slightly from that of the

Decorative layer spanned plane out. By slightly is meant here that only about 20% of

Cross-sectional area of the Lichtauskopplungselernents protrude from the plane spanned by the decorative layer level.

Due to the fact that the light-outcoupling element protrudes slightly from the decorative layer, the proportion of the light that is parallel to or in the direction of the decorative layer of the light

Interior parts of the vehicle radiated will be increased, so that shares of light effects caused by direct and indirect lighting are achieved in this way are adjustable.

In a particularly preferred embodiment, the light extraction element from a first position in which the light extraction element is flush with that of the

Decorative layer spanned level exists _. , be spent in at least a slightly outstanding position. For this purpose, the light extraction element may at least partially consist of a so-called smart material or intelligent material, which preferably changes its properties selectively, for example expands or otherwise deformed when applying a temperature or voltage or when light is shone into the light extraction element.

Advantageously, the light extraction element can be controlled such that a sequence of positions

is einsteilbar in which the light-outcoupling element or certain portions of the light-outcoupling element more or less protrudes from the decorative layer / protrudes.

This allows a dynamic lighting effect of the direct and indirect ambient lighting can be achieved

for example, a wave motion.

Preferably, the reflection element has at least one

Reflection surface, with which from the

Lichtauskopplungselement parallel to or in the direction of the decorative layer of the interior trim part of the vehicle radiated light can be deflected in the direction of the vehicle interior.

In a preferred embodiment, this is

Reflection element itself formed as a reflection surface. For example, the reflection surface can be formed from light-scattering or light-reflecting particles which are at least partially embedded in one, preferably

transparent or translucent polymer layer

Of course, other fastening methods, such as stitching, are alternatively also possible (for example, a bonding agent) on the surface of the decorative layer. Riveting, welding, etc. conceivable. The particles may be, for example, sequins, beads,

Glass (hollow) spheres or glass, mineral (crystal,

Gemstone, diamond} or plastic splinter act.

Alternatively, the reflection also pushes from an applied on the decorative layer, for example by means of a well-known from the prior art Druckbehfens

Act material, at least the surface of the

Material has a higher compared to the adjacent decorative layer reflectance. Alternatively, the reflective element may be a ribbon, lace or thread-like material having a higher height compared to the decorative layer

Reflectance, which can be attached as a seam to the decorative layer, for example, or as a profile,

For example, in the form of a cadre, can be attached to the decorative layer.

It is particularly advantageous if the reflection surface is inclined at an angle to that of the decorative layer

spanned level is arranged. As a result, a larger amount of the light emitted by the light-outcoupling element from the reflection surface in the direction of

Vehicle interior to be redirected.

In this case, the reflection surface can be contoured or structured. For example, partial surfaces of the

Reflection surface have different degrees of reflection or the reflection surface itself may consist of a plurality of partial surfaces which are oriented differently in the manner of a facet cut. Also, the

Reflecting surface be designed completely or in some areas concave, convex, cambered or otherwise contoured.

Advantageously, the reflection surface with a

Light manipulation element provided, for example in the form of a coating. Such arranged

Lichtmanipulationselement could be a material or a

Having structure by interference diffraction of Light rays depending on the viewing angle to a

Variation of perceivable by the viewer color leader.

It is extremely advantageous if the reflection surface can be moved from a first position into at least a second position, in which the reflection surface is arranged inclined at an angle to the plane spanned by the decorative layer. For this purpose, the reflection element may at least partially consist of a so-called smart material or intelligent material, which preferably when applying a temperature or voltage to or at

Injection of light into the reflection element in its properties changes specifically, for example, expands or otherwise deformed. Advantageously, the

Reflection surface are controlled so that a sequence of angular positions is adjustable. As a result, a dynamic light effect of the indirect ambient lighting can be achieved, for example, a wave motion.

It is preferred if the angle enclosed by the reflection surface and the plane spanned by the decorative layer is less than 30 °, particularly preferably less than 15 °. This can ensure that the

Reflection surfaces not too strong from the decorative layer

excellent.

In a further embodiment, this is

Lighting element according to the invention arranged on a designed as a visible edge end side of an interior trim part with a decorative layer.

The light-outcoupling element, the light-manipulating element and / or the reflection element can be surrounded individually, in groups or together, with a transparent or translucent material, for example coated,

potted or provided with a transparent or translucent cap. This can ensure that the lighting effects achieved by the lighting according to the invention are not due to pollution, Wear or other signs of aging are reduced in their quality.

In one embodiment of the invention that are

Lichtauskopplungselement and at least the reflection ionseiement as a common component formed by the elements before assembly on the interior trim part of the vehicle indirectly or directly connected to each other, preferably already connected together during their manufacture

be executed. Such a component can be particularly easily arranged in or on a decorative layer. For example, the decorative layer recesses,

Have cutouts or Auss lights, in which the

Component is arranged. Alternatively, however, the component can also be connected to one another between or above two blanks which are used to form the decorative layer, preferably via the component, or else as one

Visible edge formed end face of a

Interior fitting parts are arranged with a decorative layer.

Preferably, at least one Lichtauskopplungselemen, at least one reflection element and at least one arranged between these elements Lichtmanipulationselement are formed as a common component.

In a very particularly preferred embodiment, the individual elements mentioned above each have a, preferably identical, connection region with which they can be connected to one another in any combination, depending on the light effect to be achieved, in the manner of a plug-in system.

It is advantageous if the reflection surfaces of the

Reflection element spaced from the light-outcoupling element can be arranged. So can between the

Light extraction element and the reflection surfaces

Lichtleitstege be arranged, with which from the light extraction element parallel to or in the direction of Decorative layer of the interior fitting part radiated light is supplied to the reflection surfaces.

In an advantageous embodiment, the are

Lichtleitstege arranged behind the decorative layer. Particularly advantageously, the Lichtleitstege can be arranged in the back provided in the decorative layer notches, ditches or channels.

In an alternative embodiment, the

Lichtleitstege within or on the decorative layer

arranged. For this purpose, indentations, trenches or channels for at least partially receiving the Lichtleitstege can in turn be provided in the decorative layer on the side. In addition to the Lichtleitstegen in the, for the

Recording the Lichtleitstege provided areas an additional material, such as an additional

Decorative material, to be arranged. This allows a further design option of an inventive

Lighting element.

Alternatively, holes may be provided within the decorative layer in which the Lichtleitstege, for example in the form of optical fibers, are arranged.

Regardless of the positioning of the light bars, they may be preferred as at least partially

Light manipulating elements are formed or to

serve certain areas of the Reflexionelernents to

Targeting the effect of an effect.

Another advantage of a spaced arrangement of the

Lichtauskopplungselements of the reflection surfaces of the

Reflection element is that the {irradiated) decorative layer arranged between these elements can be additionally used in the design of lighting effects. Thus, in a preferred embodiment, the range of

Decorative layer, which is arranged between the light extraction element and the reflection surfaces, at least partially designed as a light manipulation element or with a

Be provided light manipulation element.

Regardless of the material choice can be at a spaced

Arrangement of the reflection surfaces of the reflection element from the light extraction element of the intermediate

Connection area advantageously in addition to the determination of the component relative to the decorative layer, for example via a bonding agent used. If both sides in

Essentially parallel to the light extraction element

extending reflection elements are provided, a connection of two blanks of the decorative layer can be realized in a simple manner on the connection areas.

In a further preferred embodiment, the

Illumination element a light source, preferably a

Laser source on, with the light extraction element

connected is ,

In particular, this disclosed embodiment of the invention provides a lighting element that can be integrated as a finished module in an interior trim part. This also reduces the likelihood of malfunctioning, since a functional test can be carried out before the integration and the susceptibility to errors in the assembly of the lighting element is reduced as a module.

Even if any light source can be used as a light source, such as on a filament

based light sources or light emitting diodes are preferably used as a laser sources running light sources. With these it is possible light with a very narrow

Frequency spectrum and / or a high degree of parallelism
