Introduction
The outdoor environment is complex and changeable, especially the weather factors, which pose a severe challenge to the performance of the Affichage LED.
Among them, waterproof performance is one of the important indicators to measure the quality of outdoor LED displays. So, is your outdoor LED display really waterproof? How is it waterproof? This article will tell you in detail.
1. A brief introduction to the waterproof design of outdoor LED display
1). Waterproof grade standard
When it comes to the waterproofness of outdoor LED displays, we have to mention the IP protection grade standard. This standard is used to measure the dustproof and waterproof capabilities of the equipment.
It consists of two numbers. The first number indicates the dustproof grade, and the second number indicates the waterproof grade.
- Dustproof grade:
The larger the number, the better the dustproof effect. For example, level 6 means that dust is completely prevented from entering, and no dust can get in.
- Waterproof grade:
The larger the number, the more waterproof. Like IP65, it means that the equipment can prevent the entry of sprayed water. No matter which direction the water is sprayed from, there is no problem. IP66 is even more powerful, and it is not afraid of big waves.
Specifically, the test standard of IP65 is that the equipment must be able to withstand the test of simulated spraying water to ensure that water will not penetrate. IP66 requires the device to withstand the impact of big waves and still be leak-proof.
For outdoor LED displays, IP65 is a common waterproof level, but if it is at the seaside or in places where it rains frequently, a higher waterproof level, such as IP66, may be chosen.
2). Design features
The waterproof design of outdoor LED displays is actually quite interesting. Let me briefly talk about it:
- Shell material:
The shell of the display is generally made of special waterproof and dustproof materials, such as aluminum alloy. These materials are not only strong and durable but also have excellent waterproof effects and are not afraid of wind and rain.
- Seam treatment:
The seams of the shell are the key to waterproof design. Generally, waterproof sealants or waterproof sealing strips are used to seal to ensure that water does not penetrate the gaps. During installation, the workers will carefully check each seam to ensure that there is no risk.
- Circuit board waterproofing:
The circuit board is the heart of the display, so waterproof measures must be taken. Some circuit boards will be coated with a layer of waterproof coating, just like putting a waterproof coat on the circuit board.
Some will also install a waterproof cover on the circuit board so that even if water splashes on the circuit board, it will not cause a short circuit or damage.
- Leakage design:
Finally, some leaks will be designed at the bottom or side of the display. In this way, if water seeps in, it can be discharged in time through the leak and will not accumulate in the display and cause damage.
In general, the waterproof design of outdoor LED displays is quite clever; from material selection to seam treatment to circuit board waterproofing and leak design, all are considered carefully. In this way, we can see a clear and bright display in all kinds of bad weather!
2. What is the waterproof test and certification of outdoor LED displays?
1). Test method
The waterproof test of an outdoor LED display actually shows if it can withstand wind and rain. The test method is quite interesting, let me tell you:
1.1). Simulate outdoor environment:
- Spraying rain and snow water:
Just like giving the display a bath, use a nozzle to simulate rain and snow to see if water will seep in. I sprayed it for a long time just to make sure it could work normally, even in heavy rain and snow.
- Immersion test:
Soak the display in water, just like it accidentally fell into the water. Soak it for a while to see if water will get into it and whether it can still light up.
1.2). Dust environment test:
Put the display in a dusty place to see if it is sealed well. If dust can’t get in, it means the seal is pretty good.
1.3). Diving box test:
There is an even more ruthless one: put the display in a diving box, soak it to a certain depth, and soak it for a long time. This is like the display working underwater to see if it can withstand it.
2). Certification process
After the test, you have to get a certificate to prove that the display is really waterproof. The certification process is also very simple:
- Test according to the standard:
There is an international standard called IEC 60529, which is tested according to this standard. The testing agency will record all test results to ensure that the test is fair.
- Get a certificate after passing the test:
If the display screen passes all the tests, you can get an IP protection level certification certificate. For example, IP65 means that the display screen is dustproof and waterproof, and it is not afraid of rain or snow. IP66 is even more powerful, and it is not afraid of big waves.
In general, the waterproof test and certification of outdoor LED display screens is to see if they can withstand the test of various bad weather conditions and get a certificate to prove it. In this way, everyone will be more assured when buying.
3. What are the waterproof performance and practical applications of outdoor LED display screens?
