Outdoor LED display uses a large area, relative energy consumption is also large, heating is more obvious, high temperature in summer, it is easy to lead to the problem of heat dissipation LED display. In order to deal with the heat dissipation problem of outdoor LED display, it is necessary to adjust the design and structure of external display. In the installation stage, micro distance air permeability design is adopted, high density circuit board is designed, fans are not added as far as possible, and circuit integration is reduced. Air conditioning or fans are used for heat dissipation in special environment. In order to prevent open fire, flame retardant materials should be used for LED display wire to prevent wire aging and short circuit fire. How to protect outdoor LED display?
Summer is accompanied by hot weather, thunderstorm and long rainy season. Typhoon has a great impact on coastal cities. Large area precipitation puts forward higher protection requirements for LED display screen to prevent rain and thunderstorm.
1. Wind and earthquake resistance of outdoor LED display screen
With the application of outdoor LED display advertising more and more widely, the installation forms of LED display are more and more diversified, including wall mounted installation, mosaic installation, hoisting, roof installation, column installation and other forms. In order to use LED display device not to fall, for wind load and seismic performance, there are strict requirements on the selection of bearing steel structure steel, especially the requirements of roof installation and column installation are more stringent than other forms.
2. Lightning protection measures for outdoor LED large screen
In order to ensure good grounding, all metal boxes and back covers of LED display equipment have separate grounding terminals.
4. Control humidity inside large screen outside
When the full-color screen with humidity is powered on, it will cause corrosion of LED display components, and then cause damage; So keep in the full-color LED screen environment, do not let anything with humidity characteristics into your LED screen.
5. Active protection of outdoor LED display screen
Avoid possible problems, take the initiative to protect, try to move the large screen LED screen away from the screen; And when cleaning the screen, it should be wiped as light as possible to reduce the possibility of damage to the LED display.
6. Outdoor LED display control panel current
When playing, don’t stay on the full white, red, green, blue and other full bright screen for a long time, so as to avoid excessive current, overheat of power line, damage of LED light and influence of LED display life. Do not disassemble or splice the screen at will.
7. Use time controlled by outdoor LED display
It is suggested that the rest time of LED display screen should be more than 2 hours a day, and it should be used at least once a week in rainy season. Generally, the screen should be turned on at least once a month for more than 2 hours.
8. Outdoor LED display keeps power stable
Keep the power supply stable, and do a good job in grounding protection to avoid lightning. Do not use it in bad natural conditions, especially in strong lightning weather.
