Abstract
A lighting device for a motor vehicle has a plurality of laser light sources and an optical channel via which light from the plurality of laser light sources is conducted during the operation of the lighting device, in order to generate light spread from the conducted light in the area around the motor vehicle. The lighting device is characterized in that an optical element, which can be switched by a control device into different switching states, is provided between the plurality of laser light sources and the optical channel, a different switching state being associated with each laser light source. In each respective switching state, only light from the laser light source associated with the respective switching state is fed into the optical channel by way of the optical element. The control device is designed such that, when the light of one of the plurality of laser light sources is fed into the optical channel, the device keeps the other at least one laser light source switched off.
