Abstract
A lighting system is capable of forming pattern images at various locations while having a simplified structure. The lighting system includes a lighting device that emits light for forming a pattern image at at least one location; and a control device configured to control a target direction to which the irradiation light is emitted based on at least one of vehicle state information or vehicle surrounding information.
Claims12
A lighting system for a vehicle comprising:
- a lighting device that emits light for forming a pattern image to at least one location;
- and
- a control device configured to control a target direction to which the light is emitted based on vehicle state information,
- wherein the lighting device comprises:
- a light source unit that generates irradiation light;
- and
- a light path adjustment unit that adjusts a light path to allow the generated irradiation light to proceed in the target direction,
- wherein the light path adjustment unit includes at least one reflective surface that reflects the irradiation light to allow the generated irradiation light to proceed in the target direction,
- wherein the at least one reflective surface is configured to be tilted with respect to a main axis of the light path adjustment unit,
- wherein the main axis of the light path adjustment unit is configured to be tilted with respect to a main axis of the light source unit, thereby allowing the target direction to be determined according to a tilting angle of the main axis of the light path adjustment unit with respect to the main axis of the light source unit, and
- wherein the vehicle state information includes at least one of vehicle speed, shift stage, driving direction, or door opening state.
