Abstract
A control method of a lighting apparatus for a vehicle may include: sensing, by a sensing unit, a distance between the vehicle and a pedestrian; determining, by a control unit, whether the distance between the vehicle and the pedestrian falls within a first distance; determining, by the control unit, a walking direction of the pedestrian when the distance between the vehicle and the pedestrian falls within the first distance; and indicating, by the control unit, the walking direction to the pedestrian by operating a plurality of flap units.
Claims12
A method for controlling a lighting apparatus for a vehicle, the light apparatus comprising a light emitting unit and a flap system comprising a plurality of flap units, each flap unit configured to rotate to open or close a respective one of a plurality of openings exposing the light emitting unit, the method comprising:
- sensing a first distance between the vehicle and a pedestrian;
- determining whether the first distance is less than a second distance;
- in response to determining that the first distance is less than the second distance, determining a walking direction of the pedestrian;
- and
- controlling the plurality of flap units to collectively indicate the determined walking direction of the pedestrian,
- wherein controlling the plurality of flap units comprises controlling the plurality of flap units to sequentially rotate such that the plurality of openings is sequentially opened and then closed in a direction corresponding to the walking direction of the pedestrian,
- wherein the light apparatus further comprises (1) a display unit configured to display a color and (2) a reflecting unit configured to reflect the color displayed on the display unit, and
- wherein the method further comprises performing, while the plurality of openings is sequentially opened and then closed, (1) controlling the display unit to display the color, and (2) controlling the reflecting unit to reflect the color displayed by the display unit.
A method for controlling a lighting apparatus of a vehicle, the light apparatus comprising (1) a plurality of light emitting units, (2) a plurality of openings respectively exposing the plurality of light emitting units, and (3) a plurality of flap units configured to rotate to open or close the plurality of openings, respectively, the method comprising:
- sensing a first distance between the vehicle and a driver outside the vehicle;
- determining whether the first distance is less than a second distance;
- in response to the first distance being less than the second distance, controlling the plurality of light emitting units and the plurality of flap units to generate a welcome signal;
- and
- in response to the first distance being not less than the second distance, controlling the plurality of light emitting units and the plurality of flap units to generate a goodbye signal,
- wherein the method further comprises determining whether an ignition switch of the vehicle is turned on or turned off, and
- wherein controlling the plurality of light emitting units and the plurality of flap units to generate the welcome signal comprises:
- in response to determining that the ignition switch is turned on, controlling the plurality of flap units to sequentially rotate to expose the opening sequentially from a center of the opening toward both ends of the opening;
- turning on or off the plurality of light emitting units while the opening is opened;
- sequentially rotating the plurality of flap units to close the opening from both ends of the opening toward the center of the opening;
- and
- rotating the plurality of flap units to open the opening and turning on the plurality of light emitting units.
A method for controlling a lighting apparatus of a vehicle, the light apparatus comprising (1) a plurality of light emitting units, (2) a plurality of openings respectively exposing the plurality of light emitting units, and (3) a plurality of flap units configured to rotate to open or close the plurality of openings, respectively, the method comprising:
- sensing a first distance between the vehicle and a driver outside the vehicle;
- determining whether the first distance is less than a second distance;
- in response to the first distance being less than the second distance, controlling the plurality of light emitting units and the plurality of flap units to generate a welcome signal;
- and
- in response to the first distance being not less than the second distance, controlling the plurality of light emitting units and the plurality of flap units to generate a goodbye signal,
- wherein the light apparatus further comprises (1) a display unit configured to display a color and (2) a reflecting unit configured to reflect the color displayed on the display unit, and
- wherein the method further comprises:
- controlling the plurality of flap units to sequentially rotate such that the plurality of openings are sequentially opened and then closed;
- and
- performing, while the plurality of openings are sequentially opened and then closed, (1) controlling the display unit to display a first color, and (2) controlling the reflecting unit to reflect the first color displayed by the display unit.
