Summer is coming, for LED displays, in addition to lightning protection, we must also pay attention to the high temperature in summer, especially outdoor LED displays. In some provinces and cities, the outdoor temperature in summer is sometimes as high as 38°', and the LED display is still working non-stop. Is it dangerous for the LED display to burn at such a high temperature? Outdoor LED Screen Wholesaler tell us from the following three points How does the LED display cope with the high temperature test:
Outdoor LED Display is composed of mask, circuit board and bottom shell. The waterproof glue used for fireproof and moisture-proof LED display is also an important part of LED display. The mask and bottom shell are all made of PC glass fiber material with flame retardant function that has passed the quality verification. The circuit board is sprayed with black three-proof paint to prevent weathering and corrosion.
The larger the area of the LED display, the greater the amount of electricity used, and the more obvious the heat will be. In addition, the summer sun is violent, and the high external temperature causes difficulty in heat dissipation.
In order to solve the heat dissipation problem, it is necessary to adjust the appearance design and internal structure of the LED Display, and adopt a hollow design, high-density and high-precision design of the circuit board. The interior adopts a macro air-permeable design, which does not produce rain and does not cause the danger of short circuit of wires. Without a fan, the LED circuit load is reduced, and the inside and outside are combined to achieve efficient heat dissipation.
LED display screens are high-power electrical appliances and are prone to short circuits. However, the real quality of the LED display, from the wire to the structure, eliminates the short-circuit phenomenon. However, carelessness and negligence in the installation process may cause unexpected danger. In order to ensure safety, the manufacturer needs to guide the installation throughout the entire process, ensure that the positive and negative poles are connected, the circuit connection is firm, and the flammable materials around the LED display are removed. And regularly arrange professional and technical personnel to test and inspect the LED display.
