Abstract

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 pla…
