In summer, LED display board has to face lightning and high temperature, especially outdoor LED display board. In some places, the outdoor temperature sometimes reaches 35℃ or 38℃ in summer, but the LED display board still keeps working. Under such a high temperature, will there be any danger for the LED screen? Here are three main points about how LED display board can cope with high temperature test.
1. Excellent Material
The LED display board is composed of a mask, a circuit board and a bottom shell. The waterproof glue used for fire prevention and moisture prevention is also its important component. The mask and bottom shell are all made of PC glass fiber material with flame retardant function that has passed quality verification. The circuit board is sprayed with black conformal coating to prevent weathering and corrosion.
2. Good Heat Dissipation
The larger the area of the LED screen display, the more power it uses. More heat will be generated. The summer sun exposure makes it difficult to dissipate heat with high external temperature.
In order to solve the heat dissipation problem, it is necessary to adjust the exterior design and internal structure of LED display. Adopt hollow design and use high-density and high-precision circuit board. The interior adopts macro-air-permeable design, which does not cause rain accumulation and short-circuit danger of wires. No fan is installed to reduce the circuit load. High-efficiency heat dissipation is achieved by combining inside and outside.
3. Standard Installation
LED display is a high-power electrical appliance, which is prone to short circuit. Bur the high quality LED display board can avoid short circuit from wire to structure. However, a little carelessness and negligence in the installation process may cause unexpected danger. In order to ensure safety, it is necessary for the manufacturer to guide the installation in the whole process to ensure that the positive and negative poles are connected correctly and the circuit is connected firmly. At the same time, clear flammable materials around the LED display and regularly arrange professional and technical personnel to test and inspect it.
