FIELD: physics. ^ SUBSTANCE: traffic light has a housing with sealing elements, elements for fastening to the housing, a panel having a protective visor and a protective transparent glass lens. There are two electronic information units mounted inside the housing. One unit has a signalling device with a digital display of the countdown of duration of the signal which allows or prohibits movement of traffic, and an indicator for repeated switching on of previous readings of the traffic light. The other unit has an indicator of mandatory directions of movement of vehicles on the main road and secondary road. This and the other unit contain light sources with controlled illumination colour of the signal which allows or prohibits movement of vehicles. These sources form the digital display, the indicator for mandatory directions of movement of vehicles, the indicator for repeated switching of previous readings of signalling devices and the indicator for pedestrian crossing, fitted with an electrical control circuit when using the traffic light as a traffic light for the pedestrian. The control circuit includes elements for automatic setup on signals coming from the traffic light controller, elements for automatic setup of brightness of light sources depending on the time of the day and weather conditions, elements for matching readings of the digital display with the corresponding readings of the indicator of the direction of movement of vehicles and readings of the indicator of pedestrian crossing. ^ EFFECT: invention increases information content of components of traffic lights. ^ 3 cl, 7 dwg |
