Abstract
A road finishing machine comprises a tractor and a screed hinged to the tractor to be towed behind the tractor. At the tractor, a main control platform of the road finishing machine is provided which offers space for an operator and comprises operational controls for controlling functions of the road finishing machine. 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.
Claims21
A road finishing machine comprising:
- a tractor;
- a screed hinged to the tractor to be towed behind the tractor;
- a main control platform of the road finishing machine provided at the tractor, the main control platform offering space for an operator and comprising operational controls for controlling functions of the road finishing machine, the main control platform further having a roof;
- and
- a lighting unit with a light source provided at the roof, wherein the lighting unit comprises a housing which accommodates the light source directed upwardly towards a reflector, wherein the reflector is configured to reflect light emitted by the light source downwardly into a working area of the screed, so that the working area of the screed is illuminated indirectly, and wherein the light source comprises a plurality of LEDs that are separately switchable to adapt a size and/or a shape of an illuminated area corresponding to a configuration of the screed.
