Abstract
When a drive priority mode or a relaxation mode is selected by operation of a mode selection switch, a driver'"'"'s seat and a passenger'"'"'s seat are illuminated with white-colored to cold-colored lights that cause strain, and a second-row and a third-row seats are illuminated with warm-colored lights that can produce relaxation. Therefore, an interior can be appropriately illuminated corresponding to the difference in comfortability required for the driver'"'"'s seat, the passenger'"'"'s seat, and the second-row and the third-row seats. Furthermore, a vehicle-interior illumination device of the present invention is configured to control order of lighting on/off of corresponding reading lights at the time of opening/closing of a slide door that opens and closes a doorway.
