Position lighting device
First Claim
1. A position lighting device configured to emit at least one road irradiation beam from a vehicle onto a road, thereby making the other moving object which is positioned behind the vehicle or at a side of the vehicle recognize an existence of the vehicle, the position lighting device comprising:
- a lighting unit configured to emit the at least one road irradiation beam onto at least a portion of areas on the road behind and at the side of the vehicle;
a distance detecting unit configured to detect a distance between the vehicle and the other moving object; and
a lighting control unit configured to control the lighting unit on the basis of the distance between the vehicle and the other moving object detected by the distance detecting unit, thereby changing a state of the at least one road irradiation beam,wherein the distance detecting unit is configured to detect a plurality of types of a plurality of detection waves emitted from the other moving object, and on the basis of a type of at least one of the detection waves detected by the distance detecting unit, the lighting control unit changes the state of the at least one road irradiation beam.

Abstract
There is provided a position lighting device configured to emit at least one road irradiation beam from a vehicle onto a road, thereby making the other moving object which is positioned behind the vehicle or at a side of the vehicle recognize an existence of the vehicle. A lighting unit is configured to emit the at least one road irradiation beam onto at least a portion of areas on the road behind and at the side of the vehicle. A distance detecting unit is configured to detect a distance between the vehicle and the other moving object. A lighting control unit is configured to control the lighting unit on the basis of the distance between the vehicle and the other moving object detected by the distance detecting unit, thereby changing a state of the at least one road irradiation beam.

12. A position lighting device configured to emit at least one road irradiation beam from a vehicle onto a road, thereby making the other moving object which is positioned behind the vehicle or at a side of the vehicle recognize an existence of the vehicle, the position lighting device comprising:
-
a lighting unit configured to emit the at least one road irradiation beam onto at least a portion of areas on the road behind and at the side of the vehicle; a distance detecting unit configured to detect a distance between the vehicle and the other moving object; and a lighting control unit configured to control the lighting unit on the basis of the distance between the vehicle and the other moving object detected by the distance detecting unit, thereby changing a state of the at least one road irradiation beam wherein the lighting unit includes a plurality of light generating units configured to emit beams, and wherein in a case where the distance between the vehicle and the other moving object is relatively large, the lighting control unit performs a control of overlapping the beams emitted from the plurality of light generating units with each other, thereby forming one road irradiation beam, and in a case where the distance between the vehicle and the other moving object is relatively small, the lighting control unit performs a control of separating the beams emitted from the plurality of light generating units from each other, thereby forming a plurality of road irradiation beams.
