Road finisher with lighting

Abstract

The road finisher comprises a material hopper for receiving paving material, a screed for compacting paving material, and a main control stand which provides an operating location for an operator on the road finisher. The main control stand comprises a floor area. The road finisher comprises a lighting unit. The lighting unit is no more than 140 cm higher with respect to a vertical direction than the floor area of the main control stand. The lighting unit is arranged such that at least 60 percent of the light output emitted by the lighting unit during operation falls onto the floor area of the main control stand.

What is claimed is: 
     
         1 . A road finisher for paving a road surface on a subgrade, the road finisher comprising:
 a material hopper for receiving paving material;   a screed for compacting paving material;   a main control stand with an operating platform and a seat unit with a seat for an operator, wherein the seat unit is movable between a first position in which the seat is present at least substantially within a width of the operating platform and a second position in which at least a portion of the seat projects laterally beyond the operating platform; and   a subgrade lighting which is mounted to the seat unit and is configured in the second position of the seat unit to illuminate the subgrade.   
     
     
         2 . The road finisher according to  claim 1 , wherein the subgrade lighting is mounted to an underside of the seat unit. 
     
     
         3 . The road finisher according to  claim 1 , wherein the seat in the first position of the seat unit is at least substantially oriented in the paving travel direction of the road finisher. 
     
     
         4 . The road finisher according to  claim 1 , wherein a main direction of emittance of the subgrade lighting is inclined downward with respect to a horizontal direction by at least 30 degrees. 
     
     
         5 . The road finisher according to  claim 1 , further comprising a control device configured to activate the subgrade lighting in an automated manner when the seat unit is moved to the second position. 
     
     
         6 . The road finisher according to  claim 1 , wherein a luminosity and/or a light color of the lighting unit is adjustable individually. 
     
     
         7 . The road finisher according to  claim 1 , further comprising a brightness sensor, wherein a control device of the road finisher is configured to adjust a luminosity of the lighting unit in dependence on a sensor output by the brightness sensor. 
     
     
         8 . The road finisher of  claim 1 , further comprising a towing vehicle, wherein the screed is connected to the towing vehicle to be pulled along behind the towing vehicle, and wherein the main control stand is arranged on the towing vehicle. 
     
     
         9 . A road finisher for paving a road surface on a subgrade, the road finisher comprising:
 a material hopper for receiving paving material;   a screed for compacting paving material;   a control stand with an operating platform and a seat unit with a seat for an operator, the seat unit movable between a first position in which the seat is present at least substantially within a width of the operating platform and a second position in which the seat projects laterally beyond the operating platform;   a subgrade lighting configured to illuminate the subgrade; and   a control device which is configured to activate the subgrade lighting in an automated manner when the seat unit is moved to the second position.   
     
     
         10 . The road finisher according to  claim 9 , wherein the control device is configured to deactivate the subgrade lighting in an automated manner when the seat unit is moved to the first position. 
     
     
         11 . The road finisher according to  claim 9 , wherein the road finisher further comprises a sensor which is configured to detect a position of the seat unit, and wherein the control device controls the subgrade lighting based on an output of the sensor. 
     
     
         12 . The road finisher according to  claim 9 , wherein the control device is configured to adjust a luminosity and/or a main direction of emittance of the subgrade lighting in dependence on a paving width of the screed. 
     
     
         13 . The road finisher according to  claim 9 , further comprising a brightness sensor, wherein a control device of the road finisher is configured to adjust a luminosity of the lighting unit in dependence on a sensor output by the brightness sensor. 
     
     
         14 . The road finisher of  claim 9 , further comprising a towing vehicle, wherein the screed is connected to the towing vehicle to be pulled along behind the towing vehicle, and wherein the main control stand is arranged on the towing vehicle. 
     
     
         15 . The road finisher of  claim 9 , further comprising a towing vehicle, wherein the screed is connected to the towing vehicle to be pulled along behind the towing vehicle, and wherein the main control stand is arranged on the towing vehicle. 
     
     
         16 . A road finisher for paving a road surface on a subgrade, the road finisher comprising:
 a paving material hopper;   a paving material compacting screed;   a main control stand with an operating platform and a seat unit with an operator seat, wherein the seat unit is movable between a first position in which the seat is present at least substantially within a width of the operating platform and a second position in which at least a portion of the seat projects laterally beyond the operating platform; and   a subgrade lighting mounted to the seat unit and configured to illuminate the subgrade when the seat unit is in the second position.   
     
     
         17 . The road finisher according to  claim 16 , wherein the subgrade lighting is mounted to an underside of the seat unit. 
     
     
         18 . The road finisher according to  claim 16 , wherein the seat in the first position of the seat unit is at least substantially oriented in the paving travel direction of the road finisher. 
     
     
         19 . The road finisher according to  claim 16 , wherein a main direction of emittance of the subgrade lighting is inclined downward with respect to a horizontal direction by at least 30 degrees. 
     
     
         20 . The road finisher according to  claim 16 , further comprising a control device configured to activate the subgrade lighting in an automated manner when the seat unit is moved to the second position.
