"It is known (Bubnov VD, Dmitriev BC" Alarm systems. Their installation and maintenance. Semi-automatic and automatic blocking. Pzd- in "Transport. A copy of the pages from Fig. 1.2.2. is attached) a solution in which the dwarf traffic light contains a foundation on which the traffic light heads with optical glass lenses are installed (s). - ,, The disadvantage of the solution is its low life, i.e. low reliability. This is due to the following circumstances: .j 1. The metal (cast iron and aluminum) traffic light components are fouled for anti-corrosion purposes. It is time-consuming, expensive, the paint needs updating, with poor-quality care, corrosion processes lead to damage to the traffic light. 2. The reinforced concrete foundation is labor-consuming to manufacture, difficult to transport, requires loading mechanisms and eventually collapses under the influence of the environment. 3. The low height (dwarf) of the traffic light makes it accessible to casual passers-by. Sometimes their accidental or vandal actions lead to the breaking of glass lenses, especially the outer lens. S The technical result of the proposed solution is to increase the reliability of the traffic light. This is achieved through the use of zinc coatings (instead of paints) of metal assemblies and parts, the use of impact-resistant flame-retardant plastics instead of metal on a number of assemblies and parts, the manufacture of an outer lens of impact-resistant optical material, and the foundation of galvanized welded, stamped-welded, prefabricated. Thus, the claimed object, like the prototype, contains a foundation, nodes and parts of traffic light heads, lenses. The claimed object differs in that the metal assemblies and parts are galvanized (the zinc coating has good corrosion resistance), part of the components and assemblies are made of impact-resistant flame-retardant plastic (does not corrode, durable, vandal-resistant, fireproof), the outer lens is made of impact-resistant optical material, for example, polycarbonate, the foundation is made of welded metal, stamped-welded or prefabricated and galvanized or made of impact-resistant flame-retardant plastic. .
