Powerful giant color LED display summer practical manual
In June, the LED display industry has gradually entered a tight pace of production and sales. More and more outdoor surface mount products are widely used in airports, buildings, and outdoor advertising pillars. With the summer high temperature mode that has been opened all over the country, the increasingly harsh outdoor environment has greatly tested the weather resistance of outdoor LED displays.
Powerful giant color outdoor surface mount products adopt advanced lamp surface filling technology, back side spray three anti-paint; lamp high pressure drop test (120°, 0.097Mpa) cycle boiled 50 times; high and low temperature 144 hours (-40°) -100°) thermal shock; salt spray test 72 hours test (anti-corrosion test) and other processes, quality control; provide excellent quality, waterproof and weather-resistant LED display, for the summer screen to bring security!
In the face of the special environment of high temperature, rainy and thunder in summer, it is not only dependent on the high-strength weather resistance of the LED display itself. In many cases, the omission of construction and installation and late maintenance is the result of shortening the life of the LED display and various types of occurrence. The hidden danger of failure!
In this regard, the powerful giant color for lightning protection, high temperature heat dissipation, waterproof finishing some existing experience for your reference!
LED display lightning protection in summer 1, protection against direct lightning strike: install lightning rod on the support structure of LED display (outdoor), indoor LED display or LED display with tall buildings next to it, you can not install lightning rod.
2. For the counterattack of the steel structure, connect the rigid structure to the outer casing of the LED display, do the equipotential, and do the grounding. The grounding resistance is generally less than 10 ohms. If the resistance does not meet the requirements, it will be added. Artificial grounding grid. The lightning arrester should also be grounded.
3. For the lightning current induced on the power line, install a single-phase or three-phase power supply lightning protection device on the power line. The cross-sectional area of ​​the link line of the phase line shall not be less than 10 mm square, and the cross-sectional area of ​​the connection ground line shall not be less than 16 mm square.
4. For the lightning current induced on the signal line, install a signal lightning arrester on the signal line. The signal lightning arrester depends on the signal interface of the system. If it is a network cable, install a network signal lightning arrester, and the serial interface installs a DB9 interface lightning protection device. The cross-sectional area of ​​the grounding wire should not be less than 1.5mm square.
5. For the induced current with lightning strikes, the unified distribution of professional distribution boxes and cabinets can more effectively and effectively protect the entire circuit system from the lightning induced current interference.
LED display summer heat within a <br> <br>, 20 square LED display air conditioning is not generally recommended, if the conditions permit, the use of two fan diameter of about 500mm can be, according to the size of the installation space Come to fix.
Second, more than 20 square meters of LED display 1, if the LED display installation position against the wall, and can protrude from the wall one meter position, it is recommended to select the fan according to the size of the area, the fan installation position in the top of the screen side of the line . If you buy a display with an 80-square-meter ph16 outdoor LED full-color screen, it means that you need 6 fans with a diameter of 600mm. The fan is the one that draws air outside, and the fan is installed. When you want to ensure that there is a net inside, to prevent the technicians who repair the display screen from sucking other things into the adult body when repairing the display screen. In order to waterproof, install the fan outlet on the outer aluminum-plastic panel. Aluminum shutters. The wall-mounted LED display can also be installed with air conditioners, ensuring sufficient space for the air-conditioning main unit without affecting the overall appearance of the wall. The choice of air conditioning is required, and the most commonly used air conditioners are 1.5P, 2P and 3P. The northern city uses 12 square 1P air conditioning calculation; the southern city uses 9 square 1P air conditioning calculation. If the area of ​​the LED outdoor display is relatively large, the air conditioner needs to be customized; if the area is not large, it can be purchased at the store, but it is necessary to purchase a display cooling air conditioner with call compensation function.
2. If the LED display is installed in a column, it is best to use a fan to dissipate heat. The fan is installed on the back of the large screen. The aluminum-plastic panel is placed on the top to make it into the form of blinds so that the rain does not enter the display when it rains. In the case of a double-column LED display, several louvers can be opened in the middle of the double column. This window is the air inlet, and the upper fan is the exhaust port, so that complete air convection makes the heat dissipation better.
3. If air conditioning is required, the purchase cost and the use cost must be increased, and the heat dissipation effect will be worse than the fan. It is also necessary to consider the space in which the air conditioner is installed in the space, and whether the overall appearance can be ensured.
LED display screen <br> <br> summer waterproof waterproof mainly in the prevention, the module should be chosen outdoor waterproof module, the module should brush the back of three anti-paint, selection box should also be waterproof box, seal Sex is better.
The other part needs to be implemented in the specific construction site; in the structural design, the combination of prevention and drainage; after the structure is determined, according to the characteristics of the structure, it can be considered to have a hollow bubble tube structure, a small compression set rate, and an elongation at break. Large performance sealing strip material; after selecting the sealing strip material, it is necessary to design a suitable contact surface and contact force according to the characteristics of the sealing strip material, so that the sealing strip is pressed into a dense shape. In some installations, waterproof tanks, etc., focus on protection, to ensure that there is no water inside the display. This will ensure that the display will not have any quality problems caused by human factors during the rainy season.
Secondly, for different cell board materials, a professional waterproof coating is needed. Here, the user's p10 full-color outdoor LED display is taken as an example. First of all, confirm whether the ph10 outdoor unit board is magnet adsorption or screwing (the screw effect is good, the magnet is slightly worse); secondly, there is no waterproof groove on the unit board kit, if there is any, the front waterproof is basically not a big problem, even the unit board It is no problem if it is fixed with a magnet. Finally, we also need to pay attention to the waterproof problem of the back panel of the outdoor led display, because in the process of using the display, the back panel LED display is not only heat treatment, but also has great convenience in dealing with waterproof performance. Sex. When dealing with the waterproof coating on the back side, pay more attention to the waterproof performance of the aluminum strip in the back strip display. It is necessary to use the electric drill to design a row of drains under the aluminum-plastic panel, which is beneficial to the waterproof display and the heat dissipation of the display. The best display processing method.
