Street LED screen: overview, views, mounting features and reviews

Lighting technology has long been used as a way of organizing outdoor advertising. In the process of evolution, devices of this type changed in size, shape and performance. Today, a whole segment of the so-called media screens made on the basis of light-emitting diodes has firmly formed. These panels have advantages in the form of low power consumption and durability. At the same time, the street LED screen has many varieties and modifications, which facilitates the choice of the optimal option for specific needs.

Features of LED screens

In the structural aspect, such equipment is characterized in that the working zone is formed by several segments. These are small panels, each of which has a certain number of diode elements. In order to ensure reliability, a street LED screen is sometimes connected to the power supply by segments. That is, a separate panel can have its own controller, a safety block and a power feeder. The structural group is united by the body and protective shell.

With street screens on LEDs in many ways similar and large media facades. The latter also represent a working area on a platform of diodes, which is formed by segments. Through the control controller the parameters of the complex operation are regulated and the signal with content is transmitted. But there are also significant differences between outdoor panels for LED screens from media facades. They are in size, configuration and functions. Facade systems are more thorough and in most cases are technically included in the architectural ensemble of the building. LED screens are not necessarily used on walls - it can be a temporary advertising and information panel installed, for example, on poles.

Main characteristics

The LED panel can be compared with the designer, so in each case the characteristics of such devices are almost unique. But if we consider the parameters of the components, then the data will be standard. For example, the longevity of one LED is an average of 100 thousand hours. This is an absolute record if we compare this working potential with the indices of other lighting elements, including halogen and luminescent ones. The quality of the image is affected by the number of pixels placed on the panel of the format 1 x 1 m. This value can vary from 500 to 10 thousand pixels per 1 m ² . Here, the pixel pitch is also significant, expressed by the marking P3-P10 mm. This means that, for example, outdoor LED screens P5 are based on 5 mm diodes. The lower this indicator, the more saturated and detailed the image, but at the same time the reliability of the active elements decreases because of their high frequency. The thickness of the screens can reach 100-200 mm, and the length and width are determined individually - these indicators are limited only by the conditions of installation and operation.

Varieties

LED screens vary in many features. For example, there are different ways of placing diodes on the working plane - on flat or curved lines. From the point of view of structural design, rack and cluster models are also distinguished. Finished panels can be divided into sound and silent. I must say that integration of the speaker system is often an unnecessary solution. Firstly, at a remote distance, it is difficult for users to sense outgoing sound waves. Secondly, in a city stream, where there are already quite a few outside noises, it is not so easy to get intelligible information through hearing, even if the panel is installed close. In addition, the outdoor LED screen can be different in terms of protection. The optimal class for most designs is IP54. That is, the panel has a shell that does not allow moisture to the electrical stuffing, dust, dirt, etc.

Installation of LED panels

The installation is implemented in several stages, according to the technical design. Start working activities from the laying of the cable route to the place of operation of the screen. As a part of the wiring, there is a grounding line, feeding circuit, information cable, etc. Next, the segments of the future screen are assembled into one complex. Depending on the mounting conditions, the fixation of individual panels to the working area can be carried out alternately. The main thing is that up to this point the installation infrastructure has to be prepared. Typically, LED street advertising screens are mounted on metal supporting structures with brackets. At the final stage, the panels are connected to the power supply line with the separation of the control units. By the way, there are wireless screens with their own power generators, but they are much more expensive and require a more careful approach to maintenance.

Reviews of LED street screens

To the indisputable advantages of such lighting technology include the marketing effect. Qualitatively designed advertising panels attract people's attention, decorating with it the installation site. But otherwise only the weak points of the structures are noted. This concerns both the complexity of the installation, and the problems of replacing faulty segments, as well as costs. Budget LED street screens, the prices of which are within 50-70 thousand rubles, rarely provide the most attractive effect due to modest size. A full-format multimedia displays can cost 150-200 thousand rubles.

Conclusion

Both outdoor LED screens and media facades are still available to large customers, among them heads of shopping centers, hotels, railway terminals and entertainment complexes. Nevertheless, manufacturers of such systems tend to optimize them for the needs of a large consumer audience. After all, even a small outdoor LED screen can be useful if you use its capabilities correctly. According to experts, the effectiveness of the advertising panels on LEDs is largely determined by the management system and content delivery. And in this part, users of modern media screens are practically unlimited. Suffice it to say that control can be provided directly through a computer or smartphone, or automatically - by means of the mentioned controllers.
