FIELD: lighting engineering. SUBSTANCE: device relates to spark-safe power-supply sources and is designed, to ensure spark safety of nonlinear loads of, for example, incandescent mining storage-battery caplamps operating in explosion-hazard media. Safety device has transistor switch, resistors, control transistor of current-limiting circuit, protective cut-off transistor, delay capacitor, storage battery, and loading nonlinear element if form of incandescent lamp. EFFECT: improved spark safety. 1 dwg
