A device for signal light display and environment detection includes a first light source for emitting visible light in a first spectral range in a temporally modulated manner, and a light source for emitting invisible light in a second spectral range. A lighting surface is designed to reflect and/or transmit light in the first spectral range in a diffused manner. A material layer is transparent for light in the second spectral range, or reflects this light with almost no diffusion. A deflection unit in the device deflects the light from the first light source onto the lighting surface and the light from the second light source onto the material layer. The material layer is located in relation to the deflection unit such that invisible light deflected onto the material layer is emitted for environment detection in an environment of the device.

Signal light display and environment detection by means of the same device

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.
