  • Patent number: 9944227
    Abstract: Illuminated inner trim for vehicles comprising a substrate, a decorative lining, and integrated between these a set of LEDs that can provide a decorative illumination such that when on they are visible through the decorative lining as well-defined points of light, while when off they are unseen. Specifically, when said LEDs are on and the vehicle occupants change their angle of vision with respect to the LEDs, a set of points of light will be seen with variable intensity due to the contrast between areas of direct light and areas of shade, causing a sparkling effect.
