Abstract (en)
The light signal has an adjusting unit for adjusting light intensity (6) depending on actual visual conditions (2) in position proximity of the light signal. The unit has a two-channel sensor (1) for detecting the visual conditions, where output signals of the sensor are supplied by an evaluating device (4) of a signal transmitter (7) for adjusting the light intensity of the light signal. The device has a register for storing output signal ranges of the sensors and assigned control values for the transmitter.
