PCT No. PCT/JP96/00087 Sec. 371 Date Nov. 22, 1996 Sec. 102(e) Date Nov. 22, 1996 PCT Filed Jan. 19, 1996 PCT Pub. No. WO96/22195 PCT Pub. Date Jul. 25, 1996A method and apparatus for controlling an au room lamp are provided, in which the room lamp is lit up when the ignition key is extracted from the ignition switch with an automotive door being closed, to thereby provide convenience for the driver and the passengers to get out of a car. A control unit (1) detects the on/off states of the ignition switch (2), a door switch (3) and an ignition key insertion/extraction detecting switch (4). If it is judged that the ignition key is extracted from the ignition switch with the door closed, the control unit turns on the room lamp (5) at a second luminance which is lower than a first luminance provided when the room lamp is on with the door being open, keeps the luminance of the room lamp for a predetermined time, and then turns off the room lamp.
