| 摘要 |
The invention relates to a light-controlled receiver unit for remotely controlling the control unit (SE) of a part of a system, for example for remotely controlling the door-lock control relay (SE) of a motor vehicle, by means of an optical receiver element (E2), for example a photodiode (E2), which controls an electronic receiver (W) which contains one or more amplifier elements, two optical receiver elements (E1, E2) being fitted to the system, of which receiver elements the first receiver element (E1) is connected in an optically (S, IR) controllable manner and via an electronic amplifier (V) to an optical transmitter element (D) which (D), for its part, can optically (L) re-emit the signals (IR) received by the first receiver element (E1) and the second receiver element (E2) optically receives the signals (L) transmitted by the transmitter element (D) and feeds them to the receiver (W). <IMAGE>
