The invention concerns a motor vehicle's optical system for interior lighting where the optical system includes a screen and multiple light sources disposed in series where the light sources are configured to project a screen light beam and the optical system includes a light box between the light sources and the screen and where the light box includes multiple cavities where each light source is associated with a light box cavity and where each light source is activated independently. The invention also concerns a motor vehicle's interior lighting device that includes this kind of optical system.

A panel device includes a concealing portion that allows light to pass and blurs the edge of an opening in a light-blocking layer. The light-blocking layer is arranged at the rear side of a panel unit and forms the black background of the panel unit. The concealing portion of the panel device blurs the contour of the opening in the light-blocking layer when light is emitted from the rear side of the panel device and a representation is displayed on the panel unit.

A vehicle user interface apparatus for a vehicle including a light emitting unit configured to emit light; a touch sensor configured to sense a touch; a processor configured to control the light emitting unit to emit the light in response to an event, activate the touch sensor when the light is emitted, and provide a signal to control a vehicle device corresponding to a touch input received through the activated touch sensor; and a cover covering the light emitting unit, the touch sensor, and the processor, the cover configured to transmit the light into a passenger compartment with a specific shape when the light is emitted.

An interior component for a vehicle is disclosed. The interior component may be configured to include portions facing the passenger compartment of the vehicle that can be illuminated by a light source providing light. The interior component may comprise a panel having a first side facing the passenger compartment, and a fabric having optical fibers wrapped around an edge of the panel and along at least part of the first side. The optical fibers may be coupled to the light source and configured to transmit light through the fabric. The fabric may be configured to transmit the light by total internal reflection. The fabric may be configured illuminated portions on the first side of the panel where total internal reflection is prevented to allow the light to be emitted only at the illuminated portions. The fabric may be configured with different designs, patterns or shapes corresponding to the illuminated portions.

A trim element having a coating layer defining an outer surface and an inner surface, the coating layer including at least two distinct backlit pattern areas separated by at least one opaque area preventing the passage of light from the inner surface to the outer surface. The trim element includes at least one light source for each backlit pattern area, the light source being fixed on the inner surface of the coating layer facing an opaque area while being spaced apart from the corresponding backlit pattern area. The trim element has one light guide per backlit pattern area.

A light guide device that performs uniform brightness transmitted light illumination regardless of a distance from an incident portion is provided. Light that is emitted from a light source, and enters from an incident portion of a light guide member (light guide body) made of a translucent member formed along an outer edge portion of a decorated portion, travels in the light guide portion while repeating total reflection by an inner surface of the light guide member. In the light-guiding portion, the light is guided in the decorated portion made of a translucent member from the inside of the light guide member, and is emitted outside by being scattered by the inside of the decorated portion, and in the non-light-guiding portion, the light that travels in the light guide member is prevented from traveling in the decorated portion.
