Interior lamp controlling device for motor vehicle, has sensor to detect approach of hand of person, and light control signal adaptation unit to decrease light intensity when vehicle speed is higher than predefined threshold speed

摘要

The device has an approach sensor (13) e.g. optical sensor, to detect an approach of a hand of a person. A timer (17) delivers a light control signal when the sensor detects the approach of the hand. A light control signal adaptation unit (15) receives a speed signal (Sv) from a vehicle to decrease the light intensity when the speed is higher than a predefined threshold speed. The threshold speed is about 10 kilometer per hour. The approach sensor is a light barrier type sensor or retrodiffusion sensor.
