What Should We Pay Attention To When Using Outdoor LED Fixed Displays?

With the continuous development of the urban construction process, outdoor LED display screens are being used more and more as a new media advertising carrier. The outdoor LED display can indeed bring a certain improvement to the image of the city, and the form of advertising is also flexible and diverse. However, there are still some matters needing attention in the use of outdoor LED fixed displays.

Structural design

Outdoor LED fixed displays generally have a large area, so they are still very heavy. For the LED display installed outdoors, the homepage needs to pay attention to the structural design. The installation structure should take into account the main factors such as wind resistance, earthquake resistance, and load bearing; secondly, the shape, structure, and exterior decoration design of the screen should be coordinated with the attached building or environment; moreover, consider local environmental factors, such as Air humidity, air salinity content, etc.

Light pollution

With the popularization of LED displays, the concept of "light pollution" has been introduced. So is the LED display considered "light pollution"? The international definition of light pollution is usually divided into three categories: white light pollution, artificial daylight pollution and color light pollution.

At present, my country only has relevant regulations on the glass curtain wall in the pollution of white light, and there are no relevant regulations on artificial daylight and color light pollution. But considering that color light pollution does cause people to feel uncomfortable, it should be classified as "light pollution". When designing the display screen, HSC LED has always considered the problem of light pollution prevention and control of the display screen.

Installation Precautions

1. Lightning protection measures for installation of buildings and screens

In order to prevent the display from being attacked by strong electromagnetic waves caused by lightning, the display screen and the outer packaging protective layer must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by lightning can be timely From the ground line.

2. Water proof, dust proof and moisture proof measures for the entire screen

Seamless connection should be made at the junction of the box body and the box body, as well as the junction of the screen body and the force-loaded installation object, to avoid water leakage and dampness. There must be good drainage and ventilation measures inside the screen, and if there is water accumulation inside, it can be dealt with in time.

3. Ventilation measures should be taken inside the screen

When the screen is energized and working, it will generate a certain amount of heat. If this heat is not discharged and accumulated to a certain extent, it will cause the internal ambient temperature to be too high, which will affect the operation of the integrated circuit, and can cause burnout in serious cases. The display does not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen, and the temperature of the internal environment is kept between minus 10 degrees and 40 degrees.

4. The choice of highlight wick

Choosing a high-luminance LED tube allows us to display good results even in direct sunlight, and it can also enhance the contrast with the surrounding environment, so that the audience of the picture is wider. Locally, there is still a good performance.
