Lighting device for use as indicator, brake lights, headlights, tail lights or daytime running lights in motor vehicle, has light source and light sensor arranged on common carrier

摘要

The lighting device (1) has an electro-optical light element (2) that is formed from a light source (3) and a light sensor (4) assigned to the light source. The light source and the light sensor are arranged on a common carrier (5) such that a light-sensitive surface (4.1) of the light sensor is oriented by 90 degrees with respect to a main emission direction (s) of the light source. The light sensor is oriented such that a portion of light radiation is applied on the light-sensitive surface of the light sensor. The light radiation is emitted by the light source.
