For LED displays, in addition to lightning protection, it is also necessary to pay attention to high temperature weather, especially Outdoor LED Displays. In some provinces and cities, the outdoor temperature is sometimes as high as 38°, 35°, and the LED display is still working non-stop. Is it dangerous for the LED display to be burned at such a high temperature? Let’s talk about the LED display from three aspects How to deal with the high temperature test.
First, the material selection is excellent: the LED display consists 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 fiberglass material with flame retardant function that has passed quality verification. The circuit board is sprayed with black three-proof paint to prevent weathering and corrosion.
Second, solve the problem of heat dissipation: 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 screen, adopt a hollow design, and design the circuit board 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 efficient heat dissipation.
Third, installation specifications: LED displays are high-power electrical appliances, which 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 must 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.
