FIELD: electrical engineering. SUBSTANCE: proposed invention refers to electrical communication systems. It provides for capability both to send information of broadcast programs over wires to subscribers of network and to use subscriber's network of wire broadcasting in the capacity of energy source for local individual emergency lighting of living spaces when voltage of domestic electric line is cut out. Given possibility is realized thanks to joint usage of branched out subscriber's network of wire broadcasting and economic inertia-free converter of electric energy into monochromatic noncoherent light flux of relatively high intensity. This technical approach makes it possible to orient themselves in dark living spaces under emergency situations when supply voltage fails without deterioration of quality of reception by neighboring subscribers with preservation of intelligibility of information signals of three broadcasting programs by given subscriber. System includes subscriber's network of wire broadcasting, limiting resistors, individual subscriber's receivers of information of wire broadcasting signals, low-pass filter and converter of electric energy of signals of low-frequency channel into light flux. EFFECT: improved reliability. |
