TRAFFIC LIGHT AND DEVICE, WHICH PROTECTS ITS AGAINST NOISE

traffic regulation equipment. SUBSTANCE: device has power supply and light source, which is located inside housing with protection glass and is designed as plate with light-emitting diodes with given emission color, including red, and/or yellow, and/or green. Light source is connected to power supply through noise protection unit, which has reference voltage setting unit, which is designed as bridge circuit, transistor, transistor gate, as MIS transistor. Bridge circuit with transistor gate, which is used for protection switches light source on and off and provides protection against false illumination (triggering) caused by noise and induction by means of comparison to given level of signal amplitude. EFFECT: increased reliability, increased validity of signal display, facilitated use. 12 cl, 5 dwg
