A method for regulating the light emission from a vehicle light, wherein a road user located in the light emission direction of the vehicle light is detected, and the light emission from the vehicle light is changed, whereupon response data on the response of the road user to the change in the light emission are acquired. Prediction data indicating the response expected from a road user located in the light emission direction of the vehicle light to the changed light emission are determined. The acquired response data are compared with the determined prediction data, if the prediction data deviate from the response data, the adjustment in the light emission from the vehicle light by which a reduction in the deviation is predicted is determined, and the light emission is regulated according to the determined adjustment. Further, the invention relates to a device for carrying out this method.

Method and system for regulating the light emission from a vehicle light

A device for producing an output light emission having a light source for emitting light and a first polarizing beam splitter element positioned so at least one portion of the emitted light is incident thereupon, wherein a first reflected light beam of a first polarization state and a second transmitted light beam of a second polarization state are produced. The device also includes a first liquid crystal element having at least two states which are actuated using a control unit. The first liquid crystal element at least partially reflects the first light beam, wherein the polarization state of the first light beam is altered based on the state of the first liquid crystal element. The first polarizing beam splitter element is positioned so the first light beam is incident thereupon after reflection at the first liquid crystal element.
