Street LED lights: features and benefits
Many experts consider it as one of the most promising areas of development for the segment. Made by LED-technology lamps have many advantages over traditional lamps, and also benefit in a wide range of parameters from more modern halogen and fluorescent devices. Moreover, the advantages of LEDs are expressed and structural features, and the characteristics of the luminous flux directly.
Outdoor lighting is a particularly attractive application for such lamps, since street systems have high requirements for energy-saving features. Today, street LED lights are used in the arrangement of private household plots, in the infrastructure of industrial enterprises, etc.
Features of LED technology
The technology is based on the principle of operation of the so-called white diodes, which realize bright artificial radiation.Compared with alternative lighting systems, such lamps are characterized by high environmental safety. This also applies to the active emitter of the light flux, and the elements of the hull structure. In particular, the materials do not contain toxic substances, including heavy harmful metals.
Street lights are a complicated modification of ordinary household lamps. In some ways, they are a complex of semiconductor diode components that are integrated into a durable and lightweight body with protective coatings. In addition, LED street lights suggest the use of a metal case as a radiator. Also, the structure includes boards with LEDs and an electronic driver that implements the function of the power converter. Such lamps can be used both for the organization of directional light and for general illumination of a certain zone.
Advantages of LED lights
Street lighting, as already noted, is the most demanding in terms of energy costs. With such systems in this indicator can only compete with specialized lighting complexes responsible objects of industrial infrastructure.In turn, street LED lights provide significant energy savings, while covering large areas of the service area. Another advantage relates to the characteristics of the body base. The very concept of manufacturing the design of such lamps focuses on increased security from environmental influences. Even in the budget segment, you can find models with a comprehensive protective barrier that protects the LED filling from the ingress of debris, sand, water, etc.
The operational parameters of the luminous flux of LED-lamps in street lighting systems manifest themselves most favorably. This mainly relates to high color rendering characteristics, which provides improved brightness and uniformity of radiation. Also worth noting is the high working resource. Devices can be used without maintenance for several years. It is convenient and financially beneficial if you plan to install a street LED lamp on a pole with a height of more than 3 m. The lamp will not need to be replaced every six months or a year, as is required by traditional lamps.
Varieties of LED lights
Street lights can be classified according to various criteria, but the main division is based on the type of structural performance. The most common is the classic form factor, which assumes integration into the lamp body base with reflectors. The latter make it possible to direct the luminous flux to a specific zone. These are models with a capacity from 100 to 250 W, which can illuminate the landscape garden areas, squares with sidewalks, homestead zones and platforms in front of public buildings.
If you need a more powerful source of illumination of an industrial type, then choose a spotlight installation. They have a number of structural differences, but their main feature is increased productivity.
Depending on the installation method, it is possible to distinguish street LED lamps, models for mounting on a pole, pendant devices and floor lamps in separate segments.
Features of power lanterns from the solar battery
Completely free from the need for energy supply, solar-powered lanterns are becoming increasingly popular among utilities.A feature of these LEDs is powered by energy derived from sunlight. This is a rather complex infrastructural unit of the lighting system, but it provides many advantages.
It is formed by three main components. First of all, these are panels that accumulate solar energy, which then goes to the converter unit and is sent directly to the lighting device. At the same time, LED street lights with solar batteries can act only as a general energy-saving system of a specific object. That is, a unit with solar panels, batteries can accumulate energy not only for the lamp, but also to supply other consumers of a local enterprise.
Decorative street lighting solutions
LED lights are also suitable for organizing decorative lighting. For such needs, lamps are produced in special modifications of the duralight type. These are small lighting complexes with diodes placed in plastic tapes or tubes. They are used in landscape design for the implementation of architectural contour lighting. Also LED street lights of this type can be used for spot maintenance of specific objects, such as trees, sculptures, poles, etc.
Street lighting is more active than other systems incorporates programmable control technology. For such needs, special controllers are used, representing the whole complex of lighting devices involved in the object. It can be dozens of devices that operate in accordance with a user-defined program. Moreover, the mode of operation may vary depending on external conditions. For example, a street LED flashlight with a motion sensor activates its function at the moment of approaching a person. There are also models that are automatically included when the air temperature reaches a certain value.
Led light manufacturers
The largest manufacturers of LED lamps for various purposes are Osram and Philips. They produce high-tech systems with the latest functionality, innovative management tools and reliable designs. Lampyris and HTF are also known in Russia, in the families of which you can find specialized solutions for public utilities organizations, industrial enterprises, etc.
At cost, such products are cheaper than models from Osram companies. Moreover, in the simplest modification, a street LED lamp, the price of which is about 1–1.5 thousand rubles, may fully correspond to certain premium analogues of a higher level in terms of its basic working properties.
Weak points of LED lighting
With all the advantages of outdoor LED devices are not ideal means of lighting. Among the main drawbacks of such devices can be noted high heat transfer, massive construction, unreliable operation of several lamps, combined into one electrical circuit.
For example, installing a street LED lamp on a pole, you must initially take care of the cooling system. It has already been said that the individual elements of the body act as radiators, but this may not be enough. On the other hand, LEDs lose their working properties at high temperatures, forcing the staff to take additional measures to protect the hull from exposure to intense sunlight in the summer.
How to choose street LED lights
Typically, the selection of components for the organization of street lighting is based on the finished project, which indicates the recommended parameters of the same lamps. In particular, the choice is made according to the characteristics of brightness, housing design, control system and power. For private households, you can use a LED street lamp of 100 watts, the power of which will be enough to maintain a small area. This will require 3-4 instances connected by a single control panel. Industrial and public facilities require light sources with a power potential of 250 W and more.
Obvious operational advantages of LED systems are not the determining factor in the decision to switch to lighting devices of this type. Often, lighting infrastructure modernization processes stop financial constraints. Despite the fact that LED devices can count on energy savings in terms of about 25%, compared to alternative devices, the purchase of such equipment is expensive.
Still, street LED lights are several times more expensive than conventional incandescent lamps and halogen gas discharge models.This problem is even more acute in the segment of innovative systems based on the accumulation of solar energy. Complexes of this type, in practice, require only maintenance costs, but again, the acquisition of appropriate equipment turns out to be impossible for many interested enterprises.
