With the rapid development of society, the use of LED displays is becoming more and more common, but the waterproof function of LED displays is also a concern for us. Especially for outdoor LED displays, do you have a waterproof rating for
LED Display housings? It is understood that Maipu glorious
Led Display manufacturers and technical engineers will simply comb your
Led display related knowledge.
The protection level of the LED display is generally displayed as IPXY, for example: IP56, X indicates the level of dust prevention of the
Led Display Screen to prevent intrusion of foreign objects, and Y indicates the degree of sealing of the LED display screen against moisture and water intrusion, the larger the number, the The higher the protection level, the following are the meanings of X and Y numbers.
X means the meaning of the digital code:
0 : No protection
1 : Protection of 50 mm diameter and larger solid exosomes
2 : Protection against 12.5mm diameter and larger solid exosomes
3: Protection of 2.5mm diameter and larger solid exosomes
4: Protection against 1.0mm diameter and larger solid exosomes
5 : Prevents the accumulation of harmful dust (it is impossible to completely prevent the entry of dust, but the amount of dust entering will not cause damage to the equipment)
6: Completely prevent the entry of dust (Dust should not enter the cabinet at a low pressure of 20 mbar)
Y means the meaning of the digital code
0 : No protection
1 : Water drop protection (vertically falling water drops should not cause damage)
2 : Protect the water droplets when the housing is tilted to 15 degrees, and the water drops that fall vertically should not cause damage
3 : Protection against splashed water (water or rain from the 60-degree corner to the enclosure)
4 :Protective spray (the liquid does not affect the shell from any direction)
5 :Protection of shooting water (aligning water from the cabinet without any damage)
6 :Protect strong jets (strikes water from the cabinet in every direction without any damage)
7 : Can be flooded for a short time (1m)
8 : prolonged flooding under certain pressure
For example, introducing the waterproof parameters of LED display may be easier for everyone to understand: For example, the protection level of the display screen is IP54, IP is the mark letter, number 5 is the first mark number, and 4 is the second mark number. The first marker number indicates the contact protection and foreign object protection level, and the second marker number indicates the waterproof protection level. What needs special note is that after the second characteristic number after IP is 6 and 6 or less, as the number becomes larger, the test becomes increasingly strict. In other words, the LED display identified as IPX6 can also be tested through IPX5, IPX4, IPX3, IPX2, IPX1, IPX0. The test of the second characteristic number 7 or 8 after the IP, and the test type of 6 or less are two kinds. In other words, the identifier is IPX7 or the identifier is IPX8, which does not mean that the IPX6 and IPX5 requirements are met at the same time. At the same time meet the requirements of IPX7, IPX6 LED display, can be identified as IPX7/IPX6.
Focus here on the outdoor LED display waterproof rating .
Outdoor LED full color display waterproof grade IP65, 6 is to prevent objects and dust from entering the screen, 5 is to prevent water from entering the screen in the case of spraying, of course, there is no problem for heavy rain. Outdoor waterproof LED display simple box is generally marked the front waterproof IP65, because the simple box is no back door, this design is easy to machine cooling, after the whole screen is installed, need to use aluminum plastic board and waterproof glue and other materials Waterproof edging treatment, waterproof effect also reached IP65, now outdoor full color LED display using a simple box mostly. The conventional LED outdoor light full-color screen is an outdoor module plus a closed box structure that is processed to form an outdoor waterproof display box. The waterproof display box is then assembled into an outdoor full-color screen. So the display box is the basic unit that makes up the display screen. Adopt box structure:
First, to facilitate the scheduling, aging, on-site maintenance;
Second, easy packaging and transportation;
Third, on-site installation and removal is convenient. A display module is mounted on the front of the display box, and a display driver circuit board is fixed inside the box. The switching power supply is mounted on the back cover of the cabinet. In the back cover of the box is also installed exhaust fan, punching louver and so on. The box body is sprayed with inner and outer surfaces to provide functions such as anti-corrosion, moisture-proof, oxidation-proof, and flame-retardant, which guarantees the safety of the display screen.
In terms of the structure of the display,
The first module should be an outdoor waterproof module.
The back of the second module should be painted with three anti-paints.
Third, the box should be a waterproof box, sealing is better, you can do a waterproof test, sprinkle water test on the surface of the display.
After a number of tests, the IP protection level of the outdoor LED display waterproof case must achieve IP65 to achieve true waterproof.
