PEDESTRIAN TRAFFIC LIGHTS SYSTEM Russian patent published in 2005 - IPC

FIELD: engineering of local alarm and notification informational systems for pedestrians.

SUBSTANCE: device has body with immovably held protective lens glass on it and inner light sources in form of light diode matrices mounted on circuit boards and provided with electronic control circuit. Body has two sections. In upper section, light diode matrix for red signal is positioned, assembled from light diodes with red light color, forming additional shape of standing person, and matrix, made with light diodes of different color, forming segmented indicator of reversed time count. In lower section, matrix of greed signal light diodes is positioned, made with possible forming of at least two overlapping shapes of moving person with fixed movement phases. Electronic control system has elements for automatic adjustment to signals, received from road traffic lights controller, elements for automatic adjustment of brightness of light diodes in accordance to time of day, elements for synchronizing reversed time count indicator in upper section with speed of alternation of movement phases of moving person shape in lower section, elements for sound accompaniment of change of phases of movement of moving person shape in lower section, elements for time synchronization between reversed time counter in upper section with frequency of sound accompaniment of alternation of phases of movement of moving person shape in lower section and elements for automatic adjustment of volume of sound accompaniment of alternation of phases of movement of moving person shape in lower section in accordance to time of day.

EFFECT: simplified construction, higher information capacity of pedestrian traffic lights system.
