Lighting has long been used as a way to organize outdoor advertising. In the process of evolution, devices of this type have changed in size, shape, and performance. To date, a whole segment of the so-called media screens made on the basis of LEDs has firmly taken shape. These are panels that have the advantages of low power consumption and durability. At the same time, the street LED screen has many varieties and modifications, which makes it easier to choose the best option for specific needs.
Features of LED screens
Structurally, such equipment is characterized in that the working area is formed by several segments. These are small panels, each of which has a certain number of diode elements. For reliability reasons, a street LED screen is sometimes also connected to power by segments. That is, a separate panel can have its own control controller, safety block and power supply wiring. The structural group is combined with a housing and a protective shell.
Large media facades are similar in many respects to street screens on LEDs. The latter also represent the working area on the diode platform, which is formed by segments. Through the control controller, the complex operation parameters are regulated and a signal with content is transmitted. But there are significant differences between street panels for LED screens and media facades. They are in size, layout 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 the walls - this may be a temporary advertising and information panel mounted, 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 durability of one LED is on average 100 thousand hours. This is an absolute record when comparing this working potential with indicators of other lighting elements, including halogen and fluorescent ones. The image quality is affected by the number of pixels placed on a 1 x 1 m format panel. This value can vary from 500 to 10 thousand pixels per 1 m 2 . Here, the pixel pitch, expressed by marking P3-P10 mm, also matters. This means that, for example, P5 outdoor LED screens are based on 5 mm diodes. The lower this indicator, the richer and more detailed the image, but at the same time, the reliability of the active elements decreases due to 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 ways. For example, there are different ways of placing diodes on the working plane — along even or curved lines. From the point of view of structural performance, rack and cluster models are also distinguished. Finished panels can be divided into sound and soundless. I must say that the integration of the speaker system is often an unnecessary solution. Firstly, at a remote distance, it is difficult for users to pick up outgoing sound waves. Secondly, in a city stream, where there are already a lot of third-party noise, getting intelligible information through hearing is also not so easy, even if the panel is installed close. In addition, the street LED screen is different in degrees of protection. Optimum for most designs is considered to be IP54. That is, the panel has a shell that does not allow moisture, dust, dirt, etc. to the electrical filling.
LED Panel Mounting
Installation is carried out in several stages, according to the technical design. Work activities begin with laying a cable route to the place of operation of the screen. As part of the wiring, there is a ground line, a supply circuit, an information cable, etc. Next, segments of the future screen are assembled into one complex. Depending on the installation conditions, the fixing of individual panels to the working area can be carried out alternately. The main thing is that up to this point the installation infrastructure should be prepared. Typically, LED street advertising screens are mounted on metal-bearing structures with brackets. At the final stage, the panels are connected to the power supply line with the separation of control units. By the way, there are wireless screens with their own energy generators, but they are much more expensive and require a more careful approach to maintenance.
Reviews of LED Street Screens
The indisputable advantages of such lighting technology include the marketing effect. Well-designed advertising panels attract the attention of people, decorating with it the installation site. But otherwise, only weak points of the structures are noted. This applies to installation difficulties, and problems of replacing faulty segments, as well as cost. Budget LED street screens, the prices of which are in the range of 50-70 thousand rubles, rarely provide the same attractive effect due to their modest size. A full-screen multimedia displays can cost 150-200 thousand rubles.
Conclusion
Both street LED screens and media facades are still available rather to large customers, including the heads of shopping centers, hotels, train stations and entertainment complexes. Nevertheless, manufacturers of such systems seek to optimize them for the needs of a wide consumer audience. After all, even a small street LED screen can be beneficial if you use its capabilities correctly. According to experts, the effectiveness of advertising panels on LEDs is to a large extent determined by the control system and content delivery. And in this part, users of modern media screens have practically unlimited possibilities. It is enough to say that control can be provided directly through a computer or smartphone or automatically - through the mentioned controllers.
