TRAFFIC LIGHT DEVICE Russian patent published in 2019 - IPC G08G1/95 G08G1/00 B61L5/00 B61L5/12 

FIELD: transport traffic control systems.

SUBSTANCE: invention relates to a traffic light device. Traffic light device for light signal emission comprises a light emitter unit, which includes a light emitter, a casing assembly and a heater unit, which includes a plate-type heating glass, on the surface of which there is a conductive thin film having transparency, and which generates heat when power is supplied to the conducting thin film through a pair of electrodes. At that, the heater unit is provided on the path of the light signal emitted by the light emitter unit, before the light emitter unit in the light signal emission direction in the casing assembly, plate-type heating glass of heater unit is connected to plate glass with intermediate film between them for formation of laminated glass, at least part of plate glass circuit is made less than contour of plate-type heating glass, electrodes are provided on the pre-set parts of the plate-like heating glass behind the outline of the plate glass to supply power to the conducting thin film, wherein the electrodes are protected by a sealant.

EFFECT: maintaining visibility of the traffic light during snowfall.
