LED display waterproof knowledge

　　The division of the waterproof level of indoor outdoor LED display shell is different. The outdoor waterproof level is generally higher than the indoor, because the outdoor LED display encounters more rainy days or waterproof is more than the indoor LED display.

　　For example, the protective level IP54 of the display, the IP is the label letter, the number 5 is the first label number, and 4 is the second label number. The first tag number indicates the level of contact protection and the protection of foreign objects, and the second label number represents waterproof protection level. What needs to be specifically stated is that the second feature number 6 and 6 after the IP, as the number becomes larger, the test is gradually becoming stricter. In other words, the LED display identified as IPX6 can be tested through IPX5, IPX4, IPX3, IPX2, IPX1, IPX0. The test of the second feature number 7 or 8 after IP is two types of test types below 6 and 6. In other words, the logo is IPX7 or the logo is IPX8, which does not mean that it meets the requirements of IPX6 and IPX5 at the same time. At the same time, the LED display that meets the requirements of IPX7 and IPX6 can be identified as IPX7/IPX6.

　　Here we will focus on the waterproof level of outdoor LED display.

　　Outdoor LED full -color display IP65, 6 is to prevent objects and dust from entering the screen body. 5 can prevent water from entering the screen body when spraying. Of course, there is no problem with heavy rain. Outdoor waterproof LED display Simple boxes are generally marked with front waterproof IP65, because the simple box has no back door. This design is convenient for machine heat dissipation. After the whole screen is installed, it needs to be used with aluminum plastic plates and waterproof glue for materials. Waterproofing edges, the waterproof effect also reaches the IP65, and now the outdoor full -color LED display uses simple boxes. The full -color screen of conventional LED outdoor straight lights is the outdoor waterproof display box after the outdoor module plus closed box structure is processed. Therefore, the display box is the basic unit that forms a display body. Use the box structure:

　　1. Easy to dispatch, aging, and on -site maintenance;

　　Second, easy packaging and transportation;

　　Third, the installation and disassembly on the spot are convenient. The display module is installed in front of the box, and the interior of the box is fixed with a display drive circuit board. The switching power supply is installed on the back cover of the box. There are also row fans on the back cover of the box, making 100 -page windows. The box is sprayed in the internal and external surface, which has the functions of corrosion, moisture -proof, oxidation, flame retardant and other functions, which provides a guarantee for the safety of the display body.

　　As far as the structure of the display is concerned, the module should first be outdoor waterproof modules, and the back of the second module should be brushed three paint -proof paint. Third, the box should be a waterproof box. Sprinkle the surface of the display.

　　After a number of tests, the IP protection level of the outdoor LED display waterproof tank must reach the IP65 to achieve the real waterproof.
