LED street lamps on poles: durability and efficiency
Effective lighting of roads and sidewalks is one of the mandatory safety conditions at night on city streets, in the courtyards of high–rise buildings and private houses. In addition, the lanterns also perform an aesthetic function. Recently, street LED lamps on poles have been coping with all the listed tasks perfectly, while providing cost savings and quick payback. This article will tell you about the features of the new generation of lanterns.
LED lamps on poles: advantages of LED lamps
The main function of street lamps is to provide high–quality bright lighting with the greatest radius of action of the rays. It is LED lamps as street lamps on poles that are now rapidly gaining primacy in the rating, which is due to a list of advantages, among which the following can be distinguished:
- cost-effectiveness, which is manifested in the fact that an LED lamp, compared with incandescent lamps, consumes 20 times less electricity when creating equivalent lighting;
- shock resistance, resistance to vibration and temperature changes. LED or LED-lamps are successfully used not only for indoor, but also for outdoor lighting;
- the crystal structure of the diode prevents its destruction and rapid burnout, so the service life reaches one hundred thousand hours or more. If we take into account that on average the lamp works about four hours a day, then taking into account the warranty resource, it can last more than 60 years;
- LED street lights on poles are not a source of ultraviolet light. Therefore, when exposed to rays from LED lamps, objects do not heat up, which means that this prevents destruction in the form of tarnished paints, burning out of objects and walls.
The main disadvantages of street lamps on poles
The main disadvantage of LED products designed for street lighting is its high cost in comparison with other products belonging to this functional group. It should be noted that the model range includes copies of street LED lamps on poles, the price of which is low, but at the same time they are of lower quality, besides their service life is short.
A negative feature of these devices is also that lamps on diodes are prohibited for installation in capsules or closed-type lanterns due to the lack of ventilation in them. If the diode heats up to 60 ° C, it will fail pretty soon. At the same time, the LED becomes cloudy, that is, its degradation occurs. The emitted light loses its brightness, which no longer corresponds to the original technical characteristics.
Useful advice! When buying LED lamps for street lighting on poles, preference should be given to manufacturers known in this industry. This list includes companies such as Nichia, Philips, Osram and Cree. The products of these companies have excellent indicators of the luminous flux of Lumens / Watts. In addition, these products meet our climatic conditions.
The disadvantage of LED lamps is the luminescence spectrum of the lamp, which depends on the temperature, and its adjustment occurs accordingly with the main purpose – for domestic or industrial needs.
Also, LEDs are not recommended for use in places where humidity and temperature are excessively elevated. Nevertheless, lamps of this type are very popular, so they are widely used in domestic and industrial conditions. They are especially relevant in modern street lighting.
LED street lamps on poles: types and their characteristics
The main types of LED-type street lamps are the following devices: lanterns, spotlights and decorative lamps. The most common in this list are lanterns, so we will focus on a more detailed description of this type separately.
Floodlights as street lighting are most widely used in industrial environments. They are installed in spacious territories of enterprises, parking lots, stadiums and are used to illuminate buildings of administrative institutions. Most often, spotlights are used as industrial street lamps on poles.
In everyday life, small-sized weak LED spotlights are used from products of this category. With their help, house territories and estates are illuminated. The devices can emit white or multicolored light. Spotlights are mounted at different angles of light emission. As a rule, lamps with a power of 90 to 400 watts are installed in them.
Sets of various LED cords are used as decorative lamps:
Features and characteristics of street lamps on poles
The use of LED street lights on poles is very widespread. They provide illumination of highways, highways, gas stations and streets in populated areas. Less powerful copies are used in the courtyards of residential buildings and budget organizations, in parks. The lanterns used for these purposes differ structurally and in the nature of the light they emit.
Useful advice! It is better to entrust the preparation of the project, the choice of a specific type of lighting and its installation to specialists. They will perform all the necessary range of work. In addition, reliable contractors must provide warranty and post-warranty service.
In order to illuminate highways and highways, reflex lamps on poles are used, providing a versatile distribution of light. For this purpose, lamps with a power of up to 400 watts are installed in the lamps. In devices used on poles placed at gas stations, house territories, in parks, squares, courtyards of private houses and cottages, lamps with diffused light with a power of up to 150 watts are mounted. This combination provides an “extensive light intensity curve”, which consists in an even distribution of illumination in a certain area.
Varieties of street poles for lamps: choosing the optimal option
Poles intended for fixing lamps on the street are made of various materials. Their various types can be found on the streets of cities or highways. The most popular of them are the following:
- pillars made of wood, the length of which is from 6.5 to 11 m, and the diameter is from 14 to 24 cm;
- reinforced concrete structures with a length of 4 to 11 m, with a diameter of 10-40 cm;
- metal supports, cast or assembled from cast iron, aluminum or galvanized steel, their height starts from 1.5 m, and other parameters depend on the purpose of the structure;
- plastic products;
- pillars made of composite materials.
The main requirement for the supports is as follows: they must be strong and withstand wind, humidity and temperature changes. According to experts, the best option is LED street lamps on metal lighting poles, as they are durable and durable. The features of the pillars, which have a tapering structure at the top and a hollow inner part, make them both light and durable, which simplifies installation work and reduces the cost of their installation.
Of all the options, the most popular are street lamps on round columns made of galvanized steel, the length of which varies from 3 to 12 meters. Such supports are widely used in parks, streets, highways and other places. Taller structures (over 12 meters) are installed at train stations, stadiums, as well as on motorways, bridges and spacious squares.
In private estates, lamps are often mounted on fence posts. In this case, it is necessary to take care of a reliable foundation, since an increased load on the fence posts is assumed. Lamps for this option can be selected of any kind.
Varieties of outdoor DRL lamps on poles
The predecessor of LED lamps are DRL devices, which stand for arc mercury phosphor lamp of high pressure. Such devices are largely inferior in a number of characteristics to diode devices, but in many ways they have surpassed their predecessors – incandescent lamps. In addition, it should be noted that the price of a street lamp with DRL lamps is much more attractive than the cost of its LED counterparts. Lamps with DRL lamps, depending on the scope of application, are divided into two main types: cantilever and crowning (or floor lamp type).
Useful advice! In order to avoid damage, the housing of console lamps must be equipped with impact-resistant glass necessary to protect the light elements.
Console lamps got their name from the external drop-shaped appearance. They are fixed at an angle of 15 ° in relation to the horizontal surface. Most often, for street lighting, cantilever street lamps are used on pillars of 250 W DRL. In some cases, depending on the illuminated area, lamps with a power of 125 and 400 watts can be installed. The price of the product depends on this indicator.
Crowning, or floor lamps, are familiar to many street lamps – balls on poles. For their production, frosted or transparent glass is used, as well as polycarbonate. The basis for such devices are various decorative pillars or curbstones. The height of such a structure, as a rule, does not exceed five meters.
Floor lamps are also produced in the form of an inverted cone equipped with a device for light scattering. This type of lamps is considered decorative. It is used as lighting and decoration on household plots and in small parks and squares. The power of DRL lamps is 125 or 150 watts.
Console LED street lamp: features of the device and its purpose
One of the most common types of lamps is cantilever. Their design assumes one rigid fastening. The main element of fixing is the bracket, sometimes its function is performed directly by the body of the lamp itself. Install cantilever street lamps on poles – and not only. They are mounted on masts, on supports in the form of a floor lamp, as well as on various engineering and architectural structures.
Reinforced polymer, cast aluminum or steel are used for the manufacture of the case. Metal parts are coated with a special paint that prevents the formation of corrosion. Accordingly, the price of a street cantilever lamp for poles depends on the material of manufacture and additional equipment. The bracket is made with a hole having a diameter of 46-60 mm. In the middle of the case, as a rule, there is a start-up device, a power supply unit and LED lamps directly.
The body of the lighting device is equipped with a mechanism that helps to remove heat from diode lamps, and its optical part contains reflectors, a light scattering device and optics for distributing light in the right direction.

Usually lights of this type are used in conditions with high humidity and dust content, for example, on motorways. Therefore, they must have additional equipment corresponding to the degree of protection of at least IP65. Often manufacturing companies proceed from specific customer requests, on the basis of which the price of outdoor cantilever lamps for poles is formed.
The price of outdoor cantilever LED lamps for poles
The cost of LED lamps includes many factors, including manufacturing materials and their quality, individual parts, the availability of additional protective equipment. Each customer chooses his own, the most acceptable option in terms of price. Therefore, it is necessary to determine exactly in advance the model that must meet the requirements and budget.
Despite the fact that the price of street lighting fixtures for poles with LED lamps is quite high compared to other types, they are very popular products due to their payback in just a couple of years of operation. In the future, these devices allow you to save significant funds.
When calculating the total cost of installing LED street lighting on poles, it is necessary to take into account the costs of purchasing such elements:
- lanterns or searchlights;
- posts, supports or fasteners on the fence;
- foundations for pillars;
- communications for power transmission.
Accordingly, the price of installing street lighting of this type will depend on the number of lanterns or spotlights and their type, and the cost of each of them depends on the light sources used.
Important! Poles used for street lighting lamps must withstand the load of wind force, which is equal to 160 km/ h.
Street lamps for poles: the price of lamps and installation work
The cost of the lamps and plafonds themselves is formed by manufacturers taking into account such factors:
- the power of the LED lamp – the higher this indicator, the more expensive the product, respectively;
- color temperature – cold light lamps cost more than warm light lamps;
- the size of the ceiling – the smaller the product, the cheaper it is;
- the shape and material of the ceiling – shaped models have a higher price.
For example, the price of a 100W street LED lamp for poles will be an order of magnitude lower than the cost of a 400W lamp. The price of the products also depends on the components, manufacturing technology and their dimensions. The cost of one lamp will be significantly less if you buy lighting fixtures in bulk. In addition, suppliers usually make good discounts on the condition of buying a complete set of equipment necessary for installation.
The list of costs should include delivery. To transport these devices, in order to avoid damage, it is better to use special transport. If the delivery is carried out by the supplier or manufacturer, then he is responsible for the safety of the goods. Therefore, most often transportation is included in the cost of a set of products.
The total price of street lamps for poles also includes the cost of design and installation work. It is better to entrust them to professionals. There are special firms engaged in this type of activity. They can be found on the Internet, but before that it is recommended to make inquiries, consult with experienced builders and read comments on specialized websites and forums.
Modern LED lamps are rapidly gaining primacy among other lighting devices. Moreover, their initial high cost is compensated by a quick payback and further significant savings. The devices are characterized by a wide range of use, economy, reliability and durability. They can work both from electricity and solar panels. Street lamps on poles are often equipped with a photorail, which guarantees additional savings. The product range is very wide, including goods produced by the owner of a well-known brand, as well as exclusive and designer models.
