Lighting poles - the choice and the subsequent support for the installation of street lamps

has long been accustomed to understand that lighting poles (still referred to as supports for street lighting or lampposts) are public lighting equipment, state, and therefore a draw.The question of choosing lampposts, as well as information about the features of mounting and passed by ordinary citizens, were outside of their interests.Of course, it is understood that the equipment for the parks and gardens, highways and shopping centers should be efficient and cost effective, the aesthetic side of the issue is usually left on the sidelines.So how to be happy owners of country houses and gardens?Is it possible to mix the best photometric performance, ease of use, modern design and a high degree of protection from the environment with regard to the lighting system for the infield?- Try to understand.
Light poles are different in material and manufacturing, and since construction and method of installation and the purpose of use.Consider more variety.


Classification poles for lighting ↑

  1. production material (concrete, metal, fiberglass, wood).
  2. By type of support structure (tubular, multi-faceted, conical, lattice).
  3. On purpose.

Light poles are made of metal (galvanized or plain) of reinforced concrete, composite materials (glass fiber), and sometimes you can even find wooden lampposts, often used in villages and forest areas.Wood, even after processing special impregnations, yet Me resistant to atmospheric conditions than steel and concrete, in high wind or icing wires wooden post may break, unable to bear loads.So naturally, that wooden structures are often replaced by more modern: metal, concrete or fiberglass.

Concrete lighting poles ↑

lighting columns of reinforced concrete hollow inside, reinforced for extra strength metal fittings.The layout of street lighting and transmission of electricity over long distances are possible with the use of reinforced concrete supports of lighting appropriate size and species.The cost of reinforced concrete supports of 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 heavy special equipment.Another important feature: in the event of an emergency, reinforced concrete structure will cause more harm than less heavy metal.

Concrete posts
Concrete lighting poles is not easy to install, does not attract their massiveness and lack of aesthetics

Technical progress is not limited to the search for high-strength materials for sustainable construction.The ability to smoothly adjust the lighting (depending on natural light levels), the use of lamps with high luminous efficiency, which, in fact, will significantly increase the distance between the poles of lighting, without compromising light levels - this is an incomplete list of tasks that are relevant today.

Recently, to replace expensive metal pole with a cast iron casting come cheaper products made of plastic and composite materials, instead of traditional incandescent bulbs used more economical LED light sources.

lighting poles of metal ↑

Light poles made from 4mm sheet steel, usually conical, polyhedral shape, height from 3 to 12 m. The lower part of the support is equipped with a hatch cover proper size (for the possibility of installation and maintenance).With the help of the relevant type of flange at the bottom of the column is carried out underground installation or fasteners and installation on a concrete foundation.

At the top of the column is usually mounted lighting fixtures.The height of the column lighting, as well as power Lighting equipment affect the degree of illuminance.Height decorative park lamps typically less than 3 m. Weight structure depends on the thickness and height of the metal support.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.The cost of the metal structure is largely dependent on the applied anticorrosion coating.The most frequently used method of hot-dip galvanizing, application of coatings and powder coating factory.

lighting poles made of metal are strong, graceful, poles with galvanized surface is not oxidized and do not rust

Galvanized metal surface ↑

it advisable to expose the already solid metal construction process of hot-dip galvanized?During galvanization on the surface of metals is penetration of atoms of zinc metal (diffusion), while on the surface a high strength alloy, securely protects against corrosion of metal structures (the ability of zinc as a more active metal, oxidized primarily ensures the safety of the metal due to the active electrochemicalprotection).

Under the influence of weather conditions there is a gradual thinning of the protective layer (about 1.5 microns per year), the layer thickness of 80 microns ensures the protection of the metallic structure for 30 years.As you can see, the use of galvanized constructions ensures a significant excess of normal life lighting columns.

The distance between the light poles is calculated in accordance with the planned load and capacity.
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 the service (do not require periodic painting).Form for the lighting poles can be multi-faceted, round or conical, on the support and held lighting fixture (floodlight, lamp, lamp).

There are decorative, trunk, racing, street support.The use of metal supports everything possible for both functional and decorative lighting fixtures are set to support hanging, console and torshernogo type.Steel lighting poles can be painted, and the support of aluminum very light, making it easy to transport and installation of lighting poles.

installation of lighting poles ↑

to install lighting poles needed reinforced concrete foundation with anchor mortgage with the pins to which the flange is attached column.Thus the foundation can be finished a block of reinforced concrete products manufactured at the site or by pouring concrete solution to a specially prepared formwork with welded rebar design.

We reviewed the characteristics of various types of lighting poles.Concrete lighting poles - a relatively inexpensive, durable, but very massive and require significant effort during installation, aesthetically unattractive.

Metal poles are of different designs, different height and purpose, perhaps they are not the cheapest, but nevertheless, this kind of lampposts most demanded.Numerous options for decorating metal light poles allow us to consider a lamppost as an important design element of the garden or the infield.Installing metal lampposts made in accordance with the regulations organizations that have a license.
