What are the factors that affect the price of LED light pole screens?

Recently, some companies have frequently made the slogan: they must use low prices to seize the LED light pole screen market. However, after many investigations and confirmations, this company provides completely unqualified products, including insufficient brightness, excessive weight, no energy saving, no high temperature resistance, insufficient refresh, no lightning protection, no program synchronization switching, no use of temperature control fans , Poor sealing, etc., and there are serious false propaganda at the same time. Therefore, in order to allow the market and customers to have a correct understanding and judgment of LED light pole screens, as a senior in the industry, I think it is necessary for us to make an analysis of the price of LED light pole screens in order to see and listen.

In fact, LED light pole screens are the same as cars and other products, with different prices, but more often, the prices are not comparable, especially the LED light pole screens currently on the market:

1) Unqualified products and qualified products are not comparable; 2) Products with different configurations are not comparable; 3) Products with different technical generation differences are not comparable; 4) Different grades (meet different levels of customers ) The products are not comparable. Therefore, the current LED light pole screen is still in the era of coexistence with qualified and unqualified. There are few qualified products, and the price is completely incomparable.

However, thanks to the recent establishment of Xinji as one of the most important points for stimulating economic development in the country, related 5G integrated poles and smart street lights have also become hotspots. Among them, smart light poles/smart street lights, as the core products, are more attractive Widespread attention from all walks of life, and the fundamental reason lies in the influx of 5G integrated poles in the communications industry, lighting industry, and system integration industry, even Huawei, ZTE, Dahua, Haikang, Ping An, China Everbright, China State A large number of central enterprises such as the Bank of China and China Railway have also specially formed teams to join in. For a time, 5G integrated poles and smart light poles are in the limelight.

There is an important device on the smart light pole-LED light pole screen, which has also become a big hot spot, causing a commotion among all parties in the LED display industry. Dozens of companies have advertised that their company can do LED light pole screens, some companies even start to promote them everywhere with low prices, and this is also the usual style of the LED display industry. No matter what the quality requirements of the project or customers, their strategy will always be only one: "Low price Attract you first, grab the order and then talk."

In fact, there is little relationship between the LED light pole screen and the LED display. In the light pole screen, the technical content of the display does not exceed 5%. The LED light pole screen module is completely different from the conventional display module. . LED light pole screens need exquisite structure, different parameter requirements, different functions, and intelligent control. These technical difficulties are difficult, and the cost is invisibly increased, but these are the key points to determine whether the LED light pole screen is qualified.

LED light pole screen requires 7000CD brightness, energy-saving drive, high refresh, these are mature technologies, as long as they meet the standards. However, these requirements are not necessary for conventional screens. Conventional screens only need 6000CD brightness, no energy saving is required, and refreshing requirements are not high. This is the rare possible connection between the conventional screen and the light pole screen.

The LED light pole screen requires a 360-degree exquisite appearance without dead corners, which is responsible for the appearance of the entire smart light pole, and is the embodiment of the quality and price of the whole set of smart street lights; and requires light weight, good heat conduction, and no rust, so die-cast magnesium alloy is The only choice, because the iron box is easy to rust, and the aluminum box is almost too.

The LED light pole screen is an all-metal structure, and the display surface is heat-absorbing black. In addition, it is relatively thin and light, so the internal space is very small. It is hung on the light pole a few meters above the ground. The power supply, driver, and lamp beads are used when working. , Control card, fan, etc. are all heating, which determines that the internal ultra-high temperature is difficult to control. Therefore, it is necessary to save energy in the design (less heat generation), the craftsmanship must be neat (to facilitate air circulation), and the power supply fan must not only be of good quality, but also increase the amount to ensure fast heat dissipation. At the same time, it is necessary to ensure that the LED light pole screen can work normally at about 80 degrees, which puts forward rigid requirements for the high temperature resistance of the LED light pole screen power supply and control card. The light pole screen is small but needs to display video, which requires accuracy below P4, and also requires a life span of more than 8 years, and it must work normally at noon in summer, and the brightness of the screen must be above 7000CD. These requirements are incomprehensible and difficult for companies with conventional screens, and it is also difficult to achieve.

Smart light poles focus on intelligence, so LED light pole screens must realize wireless intelligent cluster control, remote switch screen, edit programs, automatic brightness adjustment, program synchronization switching, IP broadcasting, environmental monitoring, lightning protection, remote power failure and Power management for light boxes, light bars, street lights, etc. All this requires that the LED light pole screen is a highly intelligent device, and stability is the biggest problem.
