The main control platform has a roof, wherein a lighting unit with a light source is provided at the roof. The lighting unit comprises a housing which accommodates the light source and has a reflector. The reflector is configured to reflect light emitted by the light source into a working area of the screed so that the working area of the screed is illuminated indirectly.
