In-vehicle production lighting system

1. An in-vehicle production lighting system comprising:

an acceleration sensor configured to detect a longitudinal acceleration of a vehicle;

light emitters arranged in a longitudinal direction of the vehicle at a prescribed position in a cabin of the vehicle and capable of changing light intensity and light color in a prescribed lighting pattern; and

a controller configured to generate or select the prescribed lighting pattern depending on a detection result obtained by the acceleration sensor and control the light emitters to provide a gradation display in the longitudinal direction of the vehicle.

2. The in-vehicle production lighting system according to claim 1 , wherein the acceleration sensor comprises:

a longitudinal acceleration sensor configured to detect the longitudinal acceleration of the vehicle; and

a lateral acceleration sensor configured to detect a lateral acceleration acting on the vehicle.

3. The in-vehicle production lighting system according to claim 1 , wherein the light emitters comprise LED light-emitting units.

4. The in-vehicle production lighting system according to claim 1 , wherein the prescribed position in the cabin is at least one of an inside of a door, a dashboard, a center console, or a vicinity of a shift knob of the vehicle.

5. An in-vehicle production lighting system comprising:

an acceleration sensor configured to detect a lateral acceleration of a vehicle;

light emitters arranged in a lateral direction of the vehicle at a prescribed position in a cabin of the vehicle and capable of changing light intensity and light color in a prescribed lighting pattern; and

a controller configured to generate or select the prescribed lighting pattern depending on a detection result obtained by the acceleration sensor and control the light emitters to provide a gradation display in the lateral direction of the vehicle.

6. An in-vehicle production lighting system comprising:

an acceleration sensor configured to detect an acceleration of a vehicle;

light emitters arranged at a prescribed position in a cabin of the vehicle and capable of changing light intensity and light color in a prescribed lighting pattern; and

a controller configured to generate or select the prescribed lighting pattern depending on a detection result obtained by the acceleration sensor and control the light emitters,

wherein the controller is configured to illuminate the light emitters with a prescribed warning color upon the acceleration detected by the acceleration sensor exceeding a threshold to provide a warning to an occupant of the vehicle of a sudden acceleration.

7. The in-vehicle production lighting system according to claim 1 , wherein the controller is further configured to:

control the light emitters to emit light at a first set of light intensities based on a first acceleration value, wherein each light emitter includes a different light intensity; and

control the light emitters to emit light at a second set of light intensities based on a second acceleration value, wherein each light emitter includes a different light intensity and wherein the second set of light intensities is different than the first set of light intensities.
