  • Patent number: 5831389
    Abstract: A 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.
