Abstract

A light-sensitive sensor unit, in particular for automatic switching of lighting devices, preferably in motor vehicles, including at least two light-sensitive sensors, at least one first sensor detecting the global lighting conditions, and at least one second sensor detecting the lighting conditions in predetermined directions. All light guide elements provided for the sensors are joined in one piece to form a light guide body.
