Dynamic light flux filtering system for use in motor car to minimize glare effect on eyes of driver, has central computing and control unit transmitting signal for adjusting light transmittance of partial surface of filter

摘要

The system has a detecting system (3) transferring positional data of a light source (6) to a central computing and control unit (5). Another detecting system (4) transfers position data of an eye to the control unit. The control unit computes an optical axis (A) between the eye and the light source and an intersection point (S) between the optical axis and a filter (1), from the position data. The control unit determines a partial surface of the filter, in which the intersection point lies. The control unit transmits a signal for adjusting light transmittance of the partial surface. An independent claim is also included for a dynamic light flux filtering method.
