Abstract
A vehicle lighting system in the interior of a vehicle adjusts the radiation area, the brightness, and the color temperature of light depending on the behavior, state, and posture of the passenger, so as to improve passenger convenience and upgrade interior lighting.
Claims19
An interior lighting system for a vehicle, the system comprising:
- a lighting unit including a plurality of light sources having differently set radiation areas and configured such that a brightness and a color temperature of light emitted by each of the light sources is adjustable to implement a dimming function;
- an information collector configured to confirm state information of the vehicle and to confirm passenger information including a position and a posture of a passenger in the vehicle;
- and
- a controller configured to control the lighting unit to adjust the brightness of light emitted thereby so as to emit the light to the position of the passenger when information about the position of the passenger is input through the information collector, and to adjust the color temperature of the light emitted by the corresponding lighting unit when information about the posture of the passenger is input through the information collector,
- wherein the information collector is further configured to confirm information about a leg rest of a seat of the vehicle;
- and
- wherein the controller is configured to control the lighting unit to decrease the color temperature of light emitted by the lighting unit so as to emit warm-toned light and to decrease the brightness of the light, when the leg rest of the seat in which the passenger sits is unfolded.

- wherein, for a seat configured to be swiveled, the lighting unit further includes a swiveling light source configured to generate a radiation area on the seat configured to be swiveled,
- wherein the lighting unit includes a plurality of the lighting units, and
- wherein the plurality of the lighting units includes the radiation areas on at least some back seats of the vehicle, including the seat configured to be swiveled, and further includes the swiveling light source.

- wherein the information collector is further configured to confirm eye position information of the passenger sitting in a seat of the vehicle,
- wherein the controller is configured to control the respective light sources of the lighting unit so that passenger's eyes are not included in the radiation area of the lighting unit corresponding to the seat in which the passenger sits, and
- wherein the controller is configured to receive eye position information of a driver sitting in the seat, and to control the respective light sources of the lighting unit so that the driver's eyes are included in the radiation area of the lighting unit corresponding to the seat, when a drowsy state of the driver is confirmed based on the eye position information of the driver.
