With the continuous development of led display technology, the variety of led display products has become more and more abundant, and its application scenarios have become more and more widely. Arrived, the weather is getting hotter and hotter, however, the outdoor large-scale strawberry music festival, the tour performance is basically the beginning of this season from the trend of previous years. Maipu Guangcai outdoor LED display installation should take protective and maintenance measures to prevent the outdoor environment from affecting the normal use of the LED display. How does outdoor LED display dissipate heat and prevent rain?
Outdoor led display protective measures:
1. Lightning protection measures for installation buildings and screens In order to protect the LED display from strong electromagnetic attacks caused by lightning, the screen and outer packaging protection layer of the LED display must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by lightning can be drained from the ground wire in time.
2. Waterproof, dustproof and moistureproof measures for the entire screen The joints between the box and the box, as well as the joints between the screen and the stressed installation object, should be seamlessly connected to avoid water leakage and moisture. The interior of the screen should have good drainage and ventilation measures. If there is water accumulation inside, it can be dealt with in time.
3. Regarding the selection of circuit chips In the northeastern region of our country, the temperature in winter can generally reach minus ten degrees, so when selecting circuit chips, it is necessary to choose an industry whose working temperature is minus 40 degrees Celsius, which means 80 degrees Celsius. level chip to avoid the situation that Maipu Glorious Display cannot be started due to too low temperature.
4. Maintenance of heat dissipation For outdoor LED display users, we must pay attention to the temperature change of the LED display. Because the temperature is too high, the LED display will be completely destroyed. It is recommended that the LED display within 20 square meters does not use air conditioners. , the use of two small fans is sufficient.
5. Ventilation measures should be taken inside the screen body. When the screen body is energized and operated, a certain amount of heat will be generated. If the heat cannot be discharged and accumulated to a certain extent, the internal ambient temperature will be too high, which will affect the work of the integrated circuit. Influence, serious can lead to burn, so far Maipu glorious display can not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment should be kept between minus 10 degrees and 40 degrees.
6. The selection of high-brightness wicks choose high-brightness LED tubes, which can still display good effects in the case of direct sunlight, and can also enhance the contrast with the surrounding environment, so that the audience of the picture is wider. It still performs well in places where the distance is far away and the viewing angle is wide.
