For LED displays in summer, in addition to lightning protection, it is also necessary to pay attention to severe high temperature weather, especially outdoor LED displays. In some provinces and cities, the outdoor temperature in summer is sometimes as high as 35 degrees Celsius, and the internal space temperature of the outdoor LED display screen is as high as 60-75 degrees Celsius. It is still working continuously. Will the LED display be dangerous if it is grilled at such a high temperature? From the following points, we will talk about how the LED display screen can withstand the harsh high temperature test.


How does the LED display stand up to the severe high temperature test?


First: Excellent selection of materials

The LED display is composed of a mask, a circuit board, and a bottom shell. The waterproof glue used for the fireproof and moisture-proof LED display is also an important part of the 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.


Second: Solve the heat dissipation problem

The larger the area of the LED display, the greater the amount of electricity used and the more obvious the heat generation. In summer, the 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, adopt a hollow design, install exhaust mainstream fans or air conditioners, and design circuit boards with high density and high precision. 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 high-efficiency heat dissipation.


Third: Installation specifications

Although the LED display is an energy-saving product, it uses a rated voltage of 220V. The larger the area, the greater the power consumption of the entire screen, that is, it is easier to generate heat and short-circuit. To improve the quality of LED display screens, we must start with wire materials, design, production, installation, heat dissipation system, etc., and solve the problem of poor product stability and poor heat dissipation caused by high temperature weather, which can lead to short circuits and fires. In order to ensure the safety of the LED display, it is necessary for the manufacturer to guide the installation throughout the entire process, to ensure that the power supply system is well connected and the circuit is firmly connected, and at the same time, remove the flammable materials around the LED display. The manufacturer arranges professional technicians or local technicians to regularly inspect and inspect the LED display to ensure that the LED display is stable and far-reaching.
