In recent years, with the continuous development of commercial buildings, culture, comfort, interaction and the richness of the industry is also increasingly important, such as the large atrium, sightseeing elevators, fountains, etc., so that it is commercial space pay more attention to the creation of the inner atmosphere so that customers are immersed in its shaping of the space to linger, the mall atrium commercial LED screen to show more and more forms, round, arc rows, etc. In the outdoor commercial fixed installation of LED screens are the following points of attention.
1. Commercial LED screen and the installation of lightning protection devices on the building
2. Pay attention to waterproof and leak-proof
3. Commercial LED screen chip selection
4. Commercial LED screen ventilation cooling
5. Pay attention to the light
6. Pay attention to the perspective
Display body and shell to maintain good grounding, grounding resistance less than 3 ohms, so that the lightning-caused by the large current timely discharge; display may be subject to lightning-caused by strong electrical and magnetic attacks
The screen body and the combination of the screen body and the building must be strictly waterproof and leak-proof; the screen body should have good drainage measures so that the water can be discharged smoothly once it happens; pay attention to waterproof and moisture-proof. Commercial LED screens installed outdoor, often sun and rain, wind and dust cover, the working environment are harsh. Electronic equipment that is damp will cause a short circuit or even fire, triggering a malfunction or even a fire, resulting in losses.
Commercial LED screens use industrial-grade integrated circuit chips with operating temperatures between -40°C and 80°C to prevent winter temperatures too low to make the display can not start.
Install ventilation equipment to cool down the temperature, so that the internal temperature of the screen body is between -10℃ and 40℃. Commercial LED screen body installed above the axial fan to discharge heat; display work itself to generate a certain amount of heat, if the ambient temperature is too high and poor heat dissipation, the integrated circuit may not work properly, or even be burned, so that the display system can not work properly;
To ensure that the ambient light is strong in the case of long-distance visibility, one must choose ultra-high brightness light-emitting diodes; increase the contrast. The audience is wide, the distance required to see far, wide field of view requirements; ambient light changes, especially may be subject to direct sunlight.
Display media choose new wide view tube, wide view, pure colour, consistent coordination, the life expectancy of more than 100,000 hours display media outside the package for the most popular with the edge of the square cylinder, silicone seal, no metalized assembly; its appearance is exquisite, durable, with direct sunlight, dust, water, high temperature, circuit short-circuit prevention five anti- characteristics
