It has long been accustomed to understand that the pillarslighting (still referred to as the pillars for street lighting or lampposts), lighting equipment are public, state, and therefore a draw. The choice of lamp posts, as well as information about mounting and features passed by ordinary citizens, were outside of their interests. Of course, it is understood that the equipment for parks and gardens, highways and shopping centers should be efficient and little expensive, aesthetic side of the issue is usually left on the sidelines. So how to be happy owners of country houses and gardens? Possible combination of optimal photometric performance, ease of use, modern design and a high degree of protection from environmental influences with respect to the lighting system for the infield? - Try to understand. Lampposts are various manufacturing and material, and since construction and method of installation, use and purpose. Consider more variety.

Classification for lighting poles
- In the manufacture of the material (reinforced concrete, metal, fiberglass, wood).
- By type of support structures (tubular, multi-faceted, conical, lattice).
- According to the purpose of use.
Light poles are made of metal(Simple or galvanized), made of reinforced concrete, composite materials (glass fiber), and sometimes you can even find wooden lampposts, often used in rural and forest areas. Wood, even after processing special impregnations, yet Me resistant to atmospheric conditions than steel and concrete, in strong winds, or icing wires pillar of wood can break down, unable to withstand the loads. So natural that wooden structures are often replaced by more modern: metal, concrete or fiberglass.
Reinforced concrete lighting columns
Lighting poles made of reinforced concrete hollow inside,reinforced for extra strength metal reinforcement. The layout of street lighting and transmission of electricity over long distances are possible with the use of reinforced concrete poles of lighting appropriate size and species. The cost of concrete supports coverage is much lower than the metal. But look a little aesthetic massive structures, besides moving and assembling them very labor-intensive and costly, are possible only with the use of heavy special equipment. Another important feature: in the event of an emergency reinforced concrete structure will cause much more harm than the less heavy metal.
Technical progress is not limited to the searchhigh-strength materials for sustainable construction. The ability to smoothly adjust the lighting (depending on the natural light level), the use of lamps with high luminous efficiency, that is, in fact, will significantly increase the distance between the columns of lighting, without compromising on light levels - this is an incomplete list of tasks that are relevant today.
Recently, to replace expensive metalstakes with iron cast come cheaper products made of plastic and composite materials, instead of traditional incandescent light bulbs use more fuel-efficient LED light sources.
The pillars of light metal
Light poles made from 4mm sheetsteel, usually conical, polyhedral shape, the height of from 3 to 12 m. The lower part of the support is equipped with a hatch cover with the proper size (for mounting and repair if possible). With the help of the flange of the corresponding type at the bottom of the column is carried out underground or mounting hardware and installation on a concrete foundation.
At the top of the column normally attachedlighting. The height of the lighting column, as well as power and instrumentation of electro affect the degree of illuminance. The height of the decorative park lamps usually does not exceed 3 m. The weight depends on the thickness of the metal and the support height. Typically, metal fixtures up to 1 m (various decorative lampposts for the garden), characterized by a weight of about 30 kg. In the upper part of support brackets are fastened to mounting fixtures, with subsequent attachment of lighting fixtures. metal construction cost depends on the applied anticorrosion coating. The most frequently used method of hot-dip galvanizing, the application of paint, varnish or powder coating in the factory.
Galvanized metal surface
Is it advisable to expose the already strongmetal construction process of hot dip galvanizing? In the process of galvanizing on the surface of metals there is penetration of zinc atoms in the metal (diffusion), while on the surface a high strength alloy, securely protecting from corrosion the metal structure (zinc capacity as more active metal, oxidized primarily guarantees safety of metal due to an active electrochemical protection).
Under the influence of weather conditions occurgradual thinning of the protective layer (of about 1.5 microns per year), a layer thickness of 80 micron metal structure ensures protection for over 30 years. As you can see, the use of galvanized construction ensures a significant excess of the ordinary life of the lighting support.
The distance between the light polesIt is calculated in accordance with the planned loads and power. Metal poles are resistant to changes in humidity and temperature changes, wind resistance, durability (service life of metal poles to 75 years). The galvanized coating significantly extends the service life and saves money for maintenance (not periodic painting required). Form for the lighting poles can be multi-faceted, round or conical, on the support and held lighting fixture (floodlight, lantern, lamp).
There are decorative, trunk,sports, street support. The use of metal poles for the possible arrangement of both functional and decorative lighting fixtures are installed on supports, cantilever and torshernogo type. Steel lighting poles can be painted, and the aluminum support is very light, making it easier to transport and installation of lighting poles.
Installation of lighting columns
For the installation of lighting column is requiredreinforced concrete foundation with anchor mortgages with pins, to which is attached the column flange. That foundation can be ready to block or reinforced concrete products manufactured at the site by pouring a concrete solution to a specially prepared formwork with reinforcement welded construction.
We reviewed the characteristics of different types of supportlighting. Lighting Poles, concrete - a relatively inexpensive, durable, but very massive and require significant effort during installation, aesthetically unattractive.
Metal poles come in various designs,different height and destination, perhaps they are not the cheapest, but nevertheless, this kind of lampposts most demanded. Numerous variants of decorating metal lighting poles allow us to consider a lamppost as an important element of garden design or infield. Installing metal lampposts made in accordance with the regulations organizations having a license.
