Abstract

The anti-dazzle assembly comprises an optical filter element whose optical transmission is electrically controllable and an electronic control unit including a light sensitive sensor operatively connected to the optical filter element. The electronic control unit is adapted to vary the optical transmission of the optical filter element in response to the amount of light falling on the light sensitive sensor. This anti-dazzle assembly is controlled such that the intensity of light falling on the exposed surface of the sensor is selectively measured at a plurality of different area portions of this surface. The highest value is selected and used to influence the degree of optical transmission of the filter element. In this way, the anti-dazzle assembly can be controlled much more efficiently insofar as the dangerous high intensity point-shaped light sources are clearly recognized, but strong ambient light does not have a negative influence on the control of the filter element.
