With the continuous development of led display technology, the variety of LED display products is becoming more and more abundant, and its application scenarios are more and more extensive. Because of the different temperature differences between indoor and outdoor applications, the maintenance work is different, summer is fast. By the time, the weather is getting hotter and hotter, but the outdoor large-scale strawberry music festival, the tour from the trend of previous years is basically the beginning of this season. Outdoor led display installation should be protected and maintained to prevent the outdoor environment from affecting the normal use of the led display. How does the outdoor LED display cool off and rain?
Outdoor led display protection measures:
1. Lightning protection measures for installing buildings and screens
In order to prevent the led display from being subjected to strong electromagnetic attacks caused by lightning, the screen of the led display and the outer packaging protective layer must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by thunder can be made. Can be removed from the ground in time.
2, the entire screen body waterproof, dustproof and moisture-proof measures
The joint between the box and the box, and the joint between the screen and the force-mounted object should be seamlessly connected to avoid water leakage and moisture. In the interior of the screen body, it is necessary to have good drainage and ventilation measures, and if there is water in the interior, it can be treated in time.
3, on the choice of circuit chips
In the northeastern part of China, the temperature in winter can generally reach minus ten degrees. Therefore, when selecting a circuit chip, it is necessary to select an industrial grade chip with a working temperature of minus 40 degrees Celsius and 80 degrees Celsius to avoid the temperature. Low causes the display to fail to start.
4, heat dissipation maintenance
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 inches does not use air conditioner, using two small A fan is enough.
5, the inside of the screen should be well ventilated
When the screen is energized and operated, it will generate a certain amount of heat. If the heat is not discharged, if it accumulates to a certain extent, the internal environment temperature will be too high, which will affect the work of the integrated circuit, which may cause burnt. The display does not work. Therefore, it is necessary to do the ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment is maintained between minus 10 degrees and 40 degrees.
6, the choice of highlight wick
The choice of high-brightness LED tubes allows us to display good results in direct sunlight, and it can also enhance the contrast with the surrounding environment, making the audience more wide, far away, wide viewing angle. The place still has a good performance.
Electrode Holder(welding collects ) is a vulnerable consumables, argon welding torch is clamping electrode parts, with the electrode jacketed (diversion or copper head), also known as tungsten needle clamp, tungsten rod clamp, clamp, ACTS as the clamping electrode. According to the thickness of electrode and electrode holder should choose corresponding specifications, general commonly used specifications for the 1.6, 2.4, 3.2.We have several series :10N,13N,57N,58N .
