Abstract

A device for interior illumination for a vehicle includes an array formed by multiple light sources, with which an ambient illumination and a reading illumination can be generated inside the vehicle, an additional lamp unit with which exclusively an ambient illumination can be generated inside the vehicle, and a control unit for controlling the light sources and the additional lamp unit in three modes. The control unit is designed and configured in such a way that in the first mode the light sources are controlled in such a way that exclusively a reading illumination is generated inside the vehicle; in the second mode the light sources and the additional lamp unit are controlled in such a way that exclusively an ambient illumination is generated inside the vehicle; and in the third mode the control unit simultaneously activates the first and second modes for simultaneously generating an ambient illumination and a reading illumination.
