The present invention relates to a plastic component having a visible part that is made in one single layer from a plastic molding compound and that comprises a transparent or translucent matrix, and having a light source that comprises one or more lamp elements, situated under the surface of the visible part. The visible part is implemented as essentially opaque in relation to daylight and transparent or translucent in relation to the light emitted by the lamp elements. The visible part also contains admixed effect pigments and defines a surface appearance image which, when the light source is inactive, essentially corresponds to the surface appearance image of the remaining wall of an object in which the plastic component is installed and which, when the light source is active, is essentially determined by the light source activity. The plastic component according to the invention is characterized in that the lamp elements are selected from a group which comprises light-emitting diodes, organic light-emitting diodes, and fiber-optic light systems, the lamp elements at least partially being embedded in the plastic molding compound of the visible part. The manifold uses of this plastic component comprise installation in vehicles, paneling elements, and furniture, as well as in housings of greatly varying devices.

Plastic component having visible part and light source

Relates to the use of a thermoplastic polymer molding compound for producing metallically coated light-reflecting components based on thermoplastics, which are suitable for operating temperatures of at least 200&#xb0; C. The polymer molding compound used according to the present invention is characterized in that it comprises polyamides which are selected from a group which comprises homopolyamides, copolyamides, and mixtures (blends) made of homopolyamides and copolyamides and mixtures made of homopolyamides or copolyamides, these polyamides being selected from a group which comprises amorphous and transparent polyamides, and these polyamides having a glass transition temperature (Tg) of at least 205&#xb0; C. Light-reflecting components produced according to the use according to the present invention are suitable for operating temperatures of at least 200&#xb0; C. and comprise reflectors for traveling lights of vehicles, for signal and lighting devices, and reflectors for solar collectors.
