PURPOSE:To reduce repeating times of lighting and dimming so as to obtain comfortable illumination, when a dimming compartment lamp due to boarding is present, by continuing the dimming of the compartment lamp in a light- dimming seat even when another door is opened. CONSTITUTION:For example, when a right front door as a 1st door is opened and then closed, door information relating to the right front door is stored in a memory in a door switch record block 51, and dimming for all lighted lamp is stated. Then, during the dimming of a room lamp relating to the 1st. door, if the left front door switch 11L of a 2nd door is turned on (open), seat illumination lamp 31L and a foot lamp 33L of a seat corresponding to the left front door are lighted in 100% brightness. At that time, the dimming control of a right front seat illumination lamp 31R and a right front foot lamp 33R is continued by the stored information in the memory in the record clock 51. Thus, even when the 2nd door is opened, other compartment lamps during dimming cannot be lighted in 100% brightness. |
