['1. A laser light source device comprising: a light source unit for outputting a laser beam of a first light path traveling straight to the front in a point form; an optical unit being disposed on the first light path and comprising a lens having at least one prism pattern formed thereon that deflects the light of the first light path into light of a second light path in a line shape; and a controller for controlling an incident angle of the light of the first light path with respect to the optical unit 120 so as for the line shape to have a curvature.', '6. The laser light source device of claim 5, wherein the controller comprises: a control signal receiver connected with a control device by an 12C method; and an actuator for changing an angle of the incident surface according to a control signal received through the control signal receiver.', '7. The laser light source device of claim 6, wherein the controller turns on or off the light source unit in response to the control signal included an approach or entry of a vehicle sensed by the sensor.']
