Definitions
- the present invention relates to an assembly for illuminating a decorative element, in particular for a motor vehicle, which assembly comprises the decorative element and a light guide.
- the invention further relates to a motor vehicle with such an assembly.
- the present invention is concerned with the task of specifying improved or at least different embodiments for an assembly comprising a decorative element of the type mentioned at the beginning for illuminating the decorative element and for a motor vehicle with such an assembly, which in particular eliminate disadvantages from the prior art.
- the present invention is concerned with the task of specifying improved or at least different embodiments for the assembly and for the motor vehicle, which are characterized by a space-saving design with an improved appearance.
- the present invention is therefore based on the general idea of providing a decorative element to be illuminated with a recess tapering towards the light exit side on the side facing away from the light exit side, into which a light-scattering material penetrates, whereby the light emitted via the light exit side reaches the material by means of a light guide.
- the light-diffusing material and the tapering towards the light exit side ensure uniform illumination and targeted light guidance, with the recess and the light guide simultaneously leading to a compact design. This makes the structure compact and improves the appearance perceived from the light exit side.
- an assembly comprising the decorative element also has the light guide.
- the decorative element has a front side and a rear side facing away from the front side.
- the light guide is arranged on the rear side of the decorative element and extends along the rear side.
- the decorative element has at least one recess that is open on the rear side and extends towards the front side, which tapers towards the front side and opens into at least one associated light exit opening on the front side.
- a light-scattering body is accommodated in the recess, so that light introduced into the light guide radiates via the body from the at least one associated light exit opening.
- the at least one light exit opening on the front side forms a pattern.
- the pattern is illuminated.
- the light guide preferably scatters light. This results in homogeneous light guidance within the light guide and consequently an improved appearance of the illuminated pattern.
- the light guide is preferably provided with a structure for coupling out light, which has structural elements and faces away from the front, such that light guided through the light guide radiates from the structure in the direction of the at least one body. This results in improved light guidance within the assembly and an improved appearance of the illuminated pattern.
- the structure can be of any type.
- the structure can, for example, have microstructures at least partially incorporated into the light guide.
- the microstructures can be incorporated into the light guide using appropriate tools and/or using a laser.
- the structure can, for example, have color elements, preferably white color elements, applied at least partially to a rear side of the light guide facing away from the at least one body. The color elements can be applied to the rear side in particular by means of a color print.
- the decorative element is in particular a chrome frame.
- the chrome frame is preferably a plastic component that is chrome-plated at least on the front.
- the front of the decorative element is suitably visible in an associated application, in particular it is a visible surface, so that the illuminated pattern is visible from the outside.
- the pattern can be visible from the outside when not in use, i.e. when no light is introduced into the light guide.
- the assembly can be used in any application.
- the assembly is used in a motor vehicle.
- the decorative element is therefore a decorative element of the motor vehicle.
- the decorative element can, for example, be part of a radiator grille or a fitting of the motor vehicle or form one of these.
- the decorative element has two or more such recesses, they are advantageously spaced apart from one another.
- At least one of the at least one body tapers towards the at least one associated light exit opening.
- the body at least substantially fills the associated recess.
- At least one of the at least one body can be part of the light guide.
- the light guide has the body as a projection and penetrates into the associated recess with the body. This results in improved light guidance up to the at least one associated light exit opening. In addition, this simplifies the assembly of the module.
- the respective at least one body is part of the light guide. If two or more such bodies are provided, the light guide therefore has two or more such projections, which are advantageously spaced apart from one another.
- At least one of the at least one light exit openings can be covered with a foil, in particular a hot stamping foil, so that the associated body is invisible outside of operation. This leads to an improved appearance.
- the foil in particular the hot stamping foil, can for example be one known from DE 102014 112 073 A1.
- the film in particular the hot stamping film, can be applied to the front side of the decorative element. It is also conceivable to apply the film, in particular the hot stamping film, to the side of the body facing the at least one light exit opening.
- the litter component is preferably a thermoplastic, preferably polycarbonate or "PC" for short.
- At least one of the at least one scattering component has a component inner side facing the light guide and the light guide has a conductor outer side associated with the scattering component and facing the scattering component, which run parallel and preferably flat.
- the light guide has a conductor outer side associated with the scattering component and facing the scattering component, which run parallel and preferably flat.
- At least one of the at least one recesses opens into at least two, preferably several, such light exit openings which are recessed on the front side of the decorative element. This results in an additional optical effect in the appearance, in particular in the appearance of the illuminated pattern.
- the light exit openings can be cut out in any way on the front.
- the light exit openings can be easily and precisely introduced into the decorative element using a laser, i.e. by means of a laser process.
- At least one of the at least one body penetrates into at least one of the at least one associated light exit openings.
- At least one of the at least one body is spaced apart from the front side, in particular from the at least one associated light exit opening. This means that the body cannot be seen from the outside or is at least difficult to see, which leads to an improved appearance. In addition, environmental influences on the body are prevented or at least reduced in this way, so that the durability of the assembly is improved.
- the pattern formed by means of the at least one light exit opening can be of any type.
- the pattern can be lettering.
- the pattern can also be a logo.
- Preferred embodiments are those in which the surface density of the structural elements of the structure increases towards the middle of the pattern. This means that the proportion of the structural elements per area increases towards the middle of the pattern. This leads to a homogenization of the illuminated pattern and consequently to an improved Appearance. Alternatively or additionally, the structural elements may be more pronounced towards the centre of the pattern for this purpose.
- the light for illuminating the pattern is introduced into the light guide along the front and/or along the back. This results in a compact structure of the assembly and an improved appearance.
- the light is introduced by means of at least one light source, which generates and emits light during operation.
- At least one of the at least one light source is advantageously an LED. This results in a more compact design and economical operation.
- At least one of the at least one light source can be part of the assembly and, during operation, can introduce light along the rear or the front of the light guide.
- the at least one body and/or the light guide is/are expediently fixed relative to the decorative element.
- the at least one body and/or the light guide can be glued to the decorative element. This can be done, for example, by using at least one adhesive tape.
- the light guide in particular together with the at least one light source, preferably also together with corresponding electronics, is accommodated in a housing part.
- the housing part is preferably arranged on the rear side of the decorative element and is connected to the rear side in a fluid-tight manner.
- the components accommodated in the housing part i.e. the light guide, preferably also the at least one light source, preferably also the electronics, are thus protected from external influences, in particular from the ingress of liquids.
- the fluid-tight connection can be achieved, for example, using a casting compound.
