With the coming of the rainy season in some areas, some outdoor activities will be affected. It may happen that the sky starts to rain halfway through the event.
발광 다이오드 표시 스크린 are almost essential equipment for every event, and the arrival of the rainy season also poses a challenge to its waterproof performance.
However, is your rental LED display screen waterproof up to standard?
1. What are the requirements for the waterproof performance of LED screens in the rainy season?
During the rainy season, the air humidity is high, and there is a lot of rain, which is a big challenge for outdoor LED screens. Think about it: the LED screen is full of electronic components and circuit boards. If moisture slips in, the circuit may be short-circuited, and the screen will not work properly.
In addition, if the LED lamp beads are in the water, the solder pads inside may be corroded, the lamp beads will be “dead,” and black spots will appear on the screen. For a long time, the metal parts in the screen will be oxidized and corroded, and they will have to be replaced soon.
What’s worse is that during the rainy season, the temperature difference between indoors and outdoors is large, and condensation is easy to condense on the screen.
If the screen is powered on at this time, the lamp beads may be corroded by electrolysis, and the chip inside may also have problems, causing the screen to display abnormally.
1). Specific requirements for waterproof performance
So, the LED screen used in the rainy season must have excellent waterproof performance. Specifically, it must meet these requirements:
1.1). High waterproof level:
The waterproof level of outdoor LED screens must be at least IP65. This level means that the screen can completely block dust, and it is okay to flush it with water. In this way, even if it rains heavily, the screen can still work normally without worrying about water ingress.
If it is used by the river or the sea, the waterproof level must be higher, such as IP66 or IP67. In this way, even if the wind and waves are strong, the screen can withstand it.
1.2). Dustproofing must also be considered:
Dust and impurities are not good for LED screens, so the dustproof level must also be high. Generally speaking, the dustproof level of outdoor LED screens must also reach IP6X so that dust can be completely blocked.
1.3). Good weather resistance:
The weather changes a lot in the rainy season, sometimes hot and sometimes cold, and the humidity changes all the time. Therefore, the LED screen must be able to adapt to this weather and have good weather resistance. In this way, no matter how the weather changes, the screen can work steadily.
In order to meet these requirements, the LED screen must be designed and manufactured. For example, waterproof materials must be used, the screen must be sealed well, and it must undergo rigorous testing and verification to ensure that the screen can work normally in all kinds of bad weather.
So, if you plan to use an LED screen in the rainy season, you must choose a product with good waterproof performance. In this way, you can use the screen to display information with peace of mind without worrying about the impact of the weather.
2. How to check whether your LED display is waterproof?
1). Explanation of IP protection level
First, we have to talk about the IP protection level. Simply put, the IP protection level is used to tell us how strong the dust and water resistance of this device is.
It consists of two numbers: the first number refers to the dust resistance, and the second number refers to the water resistance.
- Dust resistance level:
From 0 to 6, the larger the number, the stronger the dust resistance.
For example, 0 means no protection, 6 means completely dustproof, and dust can’t get in at all.
- Waterproof level:
It also ranges from 0 to 9 (or 8, but 9 is also a special protection level). The larger the number, the stronger the waterproof ability. For example, 0 means no protection, one means it can protect against vertically dripping water drops, and nine means it can protect against high-temperature and high-pressure water flow.
A common combination is IP65, which means that the device is completely dustproof and can also protect against low-pressure water jets, just like we use a shower head to take a shower.
2). Waterproof test method
How do you check the waterproof performance of the LED display? This requires some test methods.
- Swinging pipe water spray test:
Imagine that there is a pipe swinging back and forth, and water sprays out of the pipe and pours on the display like rain.
This pipe will swing back and forth to ensure that water can spray on the display from all directions. If the display is fine after 10 minutes of showering, it means that its waterproof performance is not bad.
- Sprinkler water test:
This is just like using a shower head to spray something, but this time it is the display screen. The sprinkler will spray water on the display screen for a period of time to see if the display screen can withstand it.
In addition to these two types, there are other tests such as vertical drip test and tilted drip test, which are used to test the performance of the display screen under different degrees of water intrusion.
3). The importance of waterproofing standards
Why do we care so much about the waterproof performance of LED display screens? This is not just for fun.
- Ensure stable operation:
Think about it, if the display screen is not waterproof, it will short-circuit when it rains, how can it be used? Especially in the rainy season, there is a lot of rain. If the display screen is waterproof, it can work steadily in the rain without various problems.
- Extend service life:
The display screen is easily damaged by rain erosion for a long time. If the waterproofing meets the standards, it can reduce the damage to the display screen by rain and make it last longer.
- Improve user satisfaction:
In the rainy season, everyone must hope that the display screen can display content steadily without problems. A waterproof display screen that meets the standard can do this, so that everyone can watch it happily and use it with confidence.
So, it is very important to check whether the waterproof performance of the LED display screen meets the standard. We must use the right method to ensure that the display screen can work steadily under various weather conditions.
3. Preparation and preventive measures before rainy season activities
1). Equipment inspection
Before rainy season activities, a comprehensive inspection of the rented LED screen is as important as checking whether we have everything in our bag before going out:
- Check whether the “raincoat” is intact:
Check whether the waterproof facilities, such as the sealing strip and waterproof rubber ring of the display screen, are intact, and whether there are any damaged or aged places. If there is a problem, you have to replace it with a new one as soon as possible.
- Ensure the health of the “body”:
Check whether the various functions of the display screen are normal, such as 명도, color, display effect, etc. You also have to check whether the connecting wires, interfaces, etc., are firm and reliable so as not to affect the entire activity because of a small problem.
2). Precautions
In order to cope with the sudden weather conditions that may be brought about by the rainy season, we have to make some preparations in advance:
- Put on “protective clothing”:
After the display screen is installed, quickly put on “protective clothing” – a waterproof cover. In this way, even if it rains, there is no need to worry about rainwater seeping in.
- Prepare a “first aid kit”:
Prepare some emergency supplies such as rainproof cloth at the event site, just like we have a first aid kit at home. In case of sudden rainfall, you can quickly cover the display screen with a rainproof cloth to prevent it from getting wet.
- Make an “escape plan”:
Oh no, it’s to make an emergency plan! For possible sudden weather conditions, formulate countermeasures in advance. For example, who is responsible for covering the display screen, who is responsible for contacting the maintenance personnel, etc., all must be arranged in advance.
In this way, even if the rainy season comes, we can deal with it calmly and ensure the smooth progress of the event!
4. Common waterproof problems and solutions for renting LED screens in the rainy season
When renting LED screens in the rainy season, waterproofing is indeed a major issue that requires special attention.
Next, let’s talk about the waterproofing problems that may be encountered when renting LED screens in the rainy season, and how to solve these problems.
1). Common problems
1.1). Aging of sealing strips:
The sealing strips are like the “gatekeepers” of the LED screen, responsible for blocking rainwater from entering.
But after long-term use, the sealing strips may become hard and cracked, just like our skin aging; at this time, its waterproof effect will be greatly reduced, and rainwater will easily take advantage of the opportunity to enter.
1.2). Deformation of waterproof rubber ring:
The waterproof rubber ring is also an important part of waterproofing. It is tightly wrapped around the joints of the LED screen to prevent moisture from penetrating. But if it is deformed, just like the collar of our clothes is loose, rainwater can easily slip in.
1.3). Water seepage in the cabinet:
The cabinet is the “home” of the LED screen. If the roof of this “home” (that is, the lid of the cabinet) is not covered well, or there are cracks in the wall (the joints of the cabinet), rainwater will take the opportunity to slip in and give the LED screen a “cold shower.”
2). Solution
2.1). Regularly check and replace the sealing strips and waterproof rubber rings:
Just like we need to regularly check whether the doors and windows of our home are closed, the sealing strips and waterproof rubber rings of the LED screen should also be checked regularly.
Once they show signs of aging or deformation, they should be replaced with new ones immediately to ensure that the “goalkeeper” and “collar” are tight.
2.2). Strengthen the sealing of the box:
The sealing of the box is a big problem. The joints must be tightly blocked with waterproof sealant or waterproof strips, just like putting a layer of waterproof clothing on the LED screen. In this way, even if it rains heavily outside, the inside can stay dry.
2.3). Take measures to combine prevention and drainage in structural design:
When designing an LED screen, waterproofing and drainage issues must be considered. For example, a small opening can be opened at the bottom of the LED screen so that the water that seeps in can be discharged in time, just like the floor drain in our home.
At the same time, some waterproofing treatment should be done on the structure to ensure that rainwater cannot enter.
2.4). Choose sealing strip materials with excellent performance:
When choosing sealing strips, you have to choose a good one.
The kind of sealing strip with hollow bubble tube structure, small compression permanent deformation rate, and large elongation at break is like the high-quality rubber bands we buy.
It is durable and elastic and has a great waterproof effect.
2.5). Regular maintenance and inspection:
Just like we need to clean the room regularly, LED screens also need regular maintenance. Regularly clean the dust and debris on the surface of the display screen to ensure its good heat dissipation performance.
Also, check whether the leak is unobstructed to prevent blockage. In this way, the LED screen can maintain a good working condition for a long time.
In general, the waterproof problem should not be underestimated when renting LED screens in the rainy season. It is necessary to start from material selection, structural design, daily maintenance and other aspects to ensure the waterproof performance of the LED screen. In this way, the LED screen can work steadily during the rainy season and provide us with a wonderful visual experience!
결론
With the advancement of technology and the continuous improvement of people’s requirements for the quality of outdoor activities, the waterproof performance of LED screens in rainy season activities will be increasingly valued.
In the future, we can expect the application of more advanced waterproof technologies and materials, as well as more complete waterproof testing standards and specifications.
At the same time, users should also continuously improve their waterproof awareness, choose LED screen products that meet the standards, and take effective waterproof measures to jointly promote the safe and stable application of LED screens in rainy season activities.
