RAILWAY DWARF TRAFFIC LIGHT Russian patent published in 2017 - IPC B61L5/00 

FIELD: physics.

SUBSTANCE: traffic light includes a set of separate cases with a back cover and a sun visor, a foundation with the transformer box fixed to it with the help of a rigid attachment, the sun visor is made of a composite structural polymer material based on polycarbonate. The case and the cover of the traffic light, as well as the case of the transformer box, are made of a composite structural polymer material based on polyamide 66, and the foundation is made of a composite mixture based on ultrahigh molecular weight polyethylene with the addition of a nanodispersed modifier in the amount of 25 wt % of ultra-high molecular weight polyethylene.

EFFECT: increasing the stiffness of the construction of a dwarf light at its own resonance frequency of longitudinal oscillations of not less than 60 Hz.
