Abstract

A lighting apparatus for a vehicle may include a light output unit; an interface unit; and at least one processor. The at least one processor may be configured to control the light output unit to generate light that illuminates an exterior of the vehicle. The at least one processor may also be configured to receive first information via the interface unit; and control the light output unit to display, via the light that illuminates the exterior of the vehicle, a visual image corresponding to the received first information. The at least one processor may further be configured to receive second information via the interface unit; and control the light output unit based on the received second information to change the visual image displayed by the light that illuminates the exterior of the vehicle.

Claims

1. A lighting apparatus for a vehicle, the lighting apparatus comprising:

a power supply unit configured to receive electrical energy from a power source in the vehicle;

a light output unit configured to generate light based on the electrical energy, and to output the light to an outside of the vehicle;

an interface unit configured to exchange signals with at least one electronic device included in the vehicle; and

at least one processor electrically connectable to the power supply unit, the light output unit, and the interface unit, and configured to control the light output unit to illuminate a first region of a road surface and to display a visual image on a second region of the road surface,

wherein the second region is positioned inside the first region, and

wherein the at least one processor is further configured to;

receive a signal related to the visual image from the at least one electronic device in the vehicle; and

control the electrical energy supplied to the light output unit to output a first light pattern for illuminating the first region of the road surface, and to output a second light pattern for displaying the visual image on the second region of the road surface.

2. The lighting apparatus according to claim 1, wherein the at least one processor is further configured to control the light output unit to output a first brightness of light for illuminating a portion of the first region of the road surface that is adjacent to the second region, and to output a second brightness of light for displaying the visual image on the second region of the road surface, wherein the second brightness of light is greater than the first brightness of light.

3. The lighting apparatus according to claim 1, wherein the at least one processor is further configured to control the light output unit to display the visual image on the second region of the road surface by outputting light for displaying the visual image within a lane of the road in which the vehicle is travelling.

4. The lighting apparatus according to claim 1, wherein the at least one processor is further configured to:

control the light output unit to illuminate the first region of the road surface based on a first signal received from the at least one electronic device of the vehicle; and

control the light output unit to display the visual image on the second region of the road surface based on a second signal received from the at least one electronic device of the vehicle.

5. The lighting apparatus according to claim 4, wherein the at least one processor is further configured to control the light output unit to display the visual image on the second region of the road surface based on a third signal received from the at least one electronic device of the vehicle to change at least one of a shape, a color, a size, a location, or a brightness of the visual image based on the third signal.

6. The lighting apparatus according to claim 5,

wherein the second signal corresponds to at least one of travel speed information, detected object information, navigation information, turn signal information, or on-board diagnostics (OBD) information, and

wherein the third signal corresponds to at least one of road information, external light information, or information about another vehicle located around the vehicle.

7. The lighting apparatus according to claim 5,

wherein the third signal corresponds to external light emission information indicating a third region of the road surface on which external light is emitted, and

wherein the at least one processor is further configured to control the light output unit to display the visual image outside of the third region of the road surface onto which the external light is emitted.

8. The lighting apparatus according to claim 5,

wherein the second signal corresponds to route information, and

wherein the at least one processor is further configured to control the light output unit to display the visual image on the second region of the road surface by displaying a turn-by-turn (TBT) image and by changing a shape of the TBT image based on the route information.
