FIELD: transport.
SUBSTANCE: invention relates to railway signaling device, namely, to signal lights that allow or inhibit train traffic ion track section. Signal light case houses glass with structure having suspended particles and two LEDs arranged ahead of light-emitting diode matrix and aligned therewith. Power is fed from power source to glass and LED matrix, said power source incorporating additionally a square pulse generator. Signal relay contacts performs double-pole making/breaking of glass and LES matrix supply circuit and connection of either straight pulse generator or constant voltage source. LEDs irradiated by LED matrix are connected to threshold device either directly or via signal relay contacts. Invention allows control over LED matrix radiation intensity in signal light normal operating conditions and in its cold state to meet traffic safety requirements.
EFFECT: reduced power consumption, longer life.
