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.

The invention relates to a lighting device for a motor vehicle, comprising a light guide for the totally reflecting guidance of light from two light sources along a light propagation axis, wherein the light from one light source can be coupled in at an in-coupling face on one end face of the light guide and the light from the other light source can be coupled in at another in-coupling face on another end face of the light guide. The light guide also has an out-coupling face arranged along the light propagation axis for coupling the light out, which light exits from the light guide at an exit face arranged along the light propagation axis where the total reflection condition is removed. The lighting device according to the invention is characterized in that the light guide is designed in such a manner that the light intensity distribution of the light from at least one light source exiting at the exit face has a gradient in the propagation direction of the light from the light source concerned, and a control device for the light sources (is provided in such a manner that, when the lighting device is switched on, the light sources are activated at a predefined switch-on time interval and thereby the brightness of at least one light source is modified on the basis of a ramped or stepped progression until a predefined brightness value is achieved.
