As an outdoor advertising LED display, its use environment is much higher than the general display. In the process of using outdoor LED display screen, due to the different environment, it is often affected by high temperature, typhoon, rainstorm, lightning and other bad weather. What preventive measures should we take to make the display screen safe in the bad weather?
1、 High temperature protection
Outdoor LED display usually has a large area, which consumes a lot of power in the application process, and the corresponding heat is also large. In addition, the external temperature is high. If the heat dissipation problem can not be solved in time, it is likely to cause the circuit board heating and short circuit problems. In production, to ensure the display circuit board in good condition, try to choose the hollow design in the shell design, which is helpful to heat dissipation. During the installation, according to the situation of the device, adhere to the display screen in good ventilation condition, and add heat dissipation equipment to the display screen when necessary, such as installing an air conditioner or fan inside to help the display screen to dissipate heat.
2、 Typhoon prevention
The installation location of outdoor LED display is different, and the installation methods are also different, including wall mounted, inlaid, column mounted, suspended and so on. So in the typhoon season, in order to make the outdoor LED display screen not fall, there are strict requirements for the load-bearing steel frame structure of the display screen. The engineering unit must design and install in strict accordance with the standard of anti typhoon level, and also have a certain anti-seismic capacity to ensure that the outdoor LED display will not fall, causing casualties and other hazards.
3、 Rainstorm prevention
There are many rainy days in the south, so the LED display must have a high waterproof protection level in order not to encounter rain erosion. In the outdoor environment, the outdoor LED display should reach the protection level of IP65, the module should be sealed by pouring glue, the waterproof box should be selected, and the module and the box should be connected with waterproof rubber ring.
4、 Lightning protection
(1) Direct lightning protection: if the outdoor LED large screen is not within the direct lightning protection range of nearby tall buildings, lightning rod shall be set on or near the top of the steel structure of the display screen;
(2) Induction lightning protection: outdoor LED display power supply system is equipped with level 1-2 power supply lightning protection, signal line is equipped with signal lightning protection device, while the power supply system of computer room is equipped with level 3 lightning protection, and signal lightning protection device is installed at the equipment end of signal out / in computer room;
(3) All LED display lines (power supply and signal) shall be laid underground and shielded;
(4) The grounding system of outdoor LED display front end and machine room should meet the system requirements. Generally, the front end grounding resistance should be less than or equal to 4 ohm, and the machine room grounding resistance should be less than or equal to 1 ohm.
Do a good job of the above protective measures, no matter how bad the environment, outdoor LED display can also run safely and safely. The above is for you to sort out the outdoor LED display knowledge, if you want to know more, want to find a high-quality outdoor LED display manufacturers.
