The system has a light emitting diode (L) producing a light beam. A housing (G) is accommodated in the diode. A translucent closing plate is locked at the front side of the housing. A data link (D1) exists between a sensor system (SE) and an electronic system (E). A function link (W1) exists between the electronic system and an actuator system (AK). Another function link (W2) exists between the electronic system and the diode. |
