Abstract

This system for detecting the surrounding conditions of a moving body forcibly changes the state of at least one of a plurality of lighting devices (change from an unlit state to a lighting state or a blinking state, change in the emission color, or change in the luminance) installed inside the moving body, if an object to which attention must be paid during traveling of the moving body is detected in the surroundings of the moving body.

Claims

1. A plurality of illumination devices disposed on a body, the plurality of illumination devices comprising:

a light emitter, positioned in an interior cabin of the body, that is configured to receive one or more drive voltages from a driver, and to generate a light output based on the one or more drive voltages received from the driver,

wherein the at least one of the plurality of illumination devices receives a command signal to transit a state of the at least one of the plurality of illumination devices between a lighting state and an unlit state, the command signal including information based on a parameter associated with a detected object, and

further wherein a power supply voltage is provided to the driver that in turn provides the one or more drive voltages to the light emitter based on the command signal, so as to cause the light emitter to generate the light output.

2. The plurality of illumination devices of claim 1, wherein the one or more drive voltages from the driver is generated based on an input from a controller and an input from a switching device.

3. The plurality of illumination devices of claim 2, wherein the switching device transits between an ON state and an OFF state based on the command signal that is received from the controller.

4. The plurality of illumination devices of claim 2, wherein the driver generates a signal that comprises one of a plurality of light emission drive voltages based on the command signal that is received from the controller, when the switching device is in an ON state.

5. The plurality of illumination devices of claim 1, wherein the light emitter is configured to light and/or blink in a prescribed color based on the one or more drive voltages received from the driver.

6. The plurality of illumination devices of claim 1, wherein the at least one of the plurality of illumination devices is provided on a side of a door facing an interior of the body.

7. The plurality of illumination devices of claim 6, wherein the door comprises a driver side door and a passenger-side door of the body.

8. The plurality of illumination devices in claim 1, wherein the light output comprises an illumination having a prescribed color.

9. The plurality of illumination devices of claim 8, wherein the prescribed color comprises at least one of yellow and orange.

10. The plurality of illumination devices of claim 1, wherein the light emitter further comprises a touch sensor panel that is configured to be received contact from an operator or a passenger of the body.

11. The plurality of illumination devices of claim 1, wherein the parameter comprises a hazard of said object.

12. The plurality of illumination devices of claim 1, wherein the parameter comprises a distance between the object and the body.

13. The plurality of illumination devices of claim 1, wherein the parameter comprises a relative speed between and the object in the body.

14. The plurality of illumination devices of claim 1, wherein the body comprises a vehicle.

15. The plurality of illumination devices of claim 1, wherein the light emitter is a light-emitting panel.

16. The plurality of illumination devices of claim 1, wherein said plurality of illumination devices is disposed in a cabin of the body.

17. The plurality of illumination devices of claim 1, wherein, when said object is present at a right side of the body, the controller forcibly causes the illumination device on the right side among said plurality of illumination devices to light or blink;

and, when said object is present at a left side of the body, the controller forcibly causes the illumination device on the left side among said plurality of illumination devices to light or blink.

18. The plurality of illumination devices of claim 1, wherein the command signal received by the at least one of the plurality of illumination devices includes a command to increase a luminance that is caused to light or blink, as a distance between the object and the body decreases.

19. The plurality of illumination devices of claim 1, wherein the command signal received by the at least one of the plurality of illumination devices includes a command to change a lighting color that is caused to light or blink, as a relative speed between the body and the object increases.

20. The plurality of illumination devices of claim 1, wherein the command signal received by the at least one of the plurality of illumination devices includes a command to increase a blinking speed of said illumination device that is caused to light or blink, as the distance between the object and the body decreases.
