Outdoor often have rain, fog and other weather effects, so outdoor LED display must be good waterproof treatment. As the outdoor LED module plus closed box structure is processed to form the LED outdoor display box, and then the box is assembled into an outdoor LED full-color display. So the LED display box is the basic unit of the display body.
The benefits of using LED box structure are as follows:
First, it is convenient for scheduling, aging, on-site maintenance;
Secondly, it is convenient for packaging and transportation;
Third, on-site installation and disassembly is convenient.
Outdoor LED display waterproof box is equipped with a display module in front of the box, the box is fixed inside the display driver circuit board. Switching power supply is installed on the back cover of the box. In the case of the back cover is also installed on the exhaust fan, punching shutters and so on. The box body adopts internal and external surface plastic spraying treatment, with anti-corrosion, moisture, oxidation, flame retardant and other functions, to provide security for the work of the display body.
As far as the structure of outdoor full-color LED display is concerned, firstly, the module should be outdoor full waterproof module, secondly, the back of the module should be brushed with three-proof paint, and thirdly, the box body should be waterproof box body with good sealing.
General LCF's outdoor box are required to do waterproof test, sprinkle test on the surface of the display, after a number of tests to ensure that the protection level should reach IP65, to achieve the true meaning of waterproof, before the final shipment to the hands of customers. In addition, the LED display box structure parts perishable parts roughly screen part of the metal column, circuit boards, terminals, connectors; water vapor sensitive parts for the circuit board, electronic components pins. Other parts of the kit, are engineering plastics (polycarbonate), epoxy, rubber, etc., not sensitive to water vapor.
The current trend is that more and more customers in the LED display waterproof box structure has more requirements, began to thin, easy to disassemble the box development, but from a professional point of view to analyze, is not fully enclosed, thin and light will certainly play a waterproof effect, the box structure is only to play a role in the dust, anti-foreign body and so on. Small space is not convenient for heat dissipation, and if a large area of water, is not conducive to handling and maintenance.
