Led advertising screen realizes the characteristics of low heat, low noise and low radiation. Through good structure introduction design and normal temperature use, it ensures working at low decibel value and stable working of the screen body. It passes EMC design test.Thunderstorm weather often brings lightning hazard to P5 full-color led display steel structure, so how to install led advertising screen steel structure lightning protection?The following LED display manufacturer derensel to share LED advertising screen steel structure lightning protection measures.

(1) for the protection of direct lightning, lightning rods should be installed on the support structure of LED advertising screens. For indoor LED advertising screens or LED advertising screens with tall buildings nearby, lightning rods should not be considered.

(2) in response to the steel frame structure, connect the steel frame structure with the shell of LED advertising screen, make equal potential, and do a good grounding, the grounding resistance value is usually required to be less than 10 ohm, if the resistance value does not meet the requirements, it is necessary to do additional manual grounding network.Lightning arresters should also be well grounded.

(3) for the lightning current induced on the power line, a single-phase or three-phase power supply lightning arrester shall be installed on the power line.The cross-sectional area of the phase line shall not be less than 10mm square, and the cross-sectional area of the ground line shall not be less than 16mm square.

(4) for the lightning current induced on the signal line, a signal lightning arrester is installed on the signal line.Signal arrester depends on the signal interface of the system. If it is a network cable, the network signal lightning arrester shall be installed, and the serial interface shall be installed with db9 interface lightning arrester.

LED advertising screen steel structure how to install lightning protection product features: full color LED screen

1.LED advertising screen spacing is small, viewing distance is closer;Using the star gold wire, copper stent high quality table lamp, horizontal and vertical Angle of 130 ° above, uniform mixing light, colour matching degree is high, good consistency and display more clearly real, fully meet the demand of outdoor display;

2. The brand new mask design of LED advertising screen makes the light emitted by LED almost reflect zero, ensuring the display effect of screen body;

3. The bottom shell of LED advertising screen is designed with reinforcing bars of quasi-architectural engineering mechanics to enhance the load-bearing tensile capacity of the product and improve the overall flatness of the product;The mask is designed with precise calculation of streaks, which greatly reduces the interference caused by the reflection of ambient light on the light tube, and ensures that the contrast of the product under all kinds of ambient light is optimal, so that the ink color of the whole screen is darker, the contrast is better, and the color of the image can be restored more realistically.

4. The cabinet design of LED advertising screen unit module adopts high-temperature spraying technology, which greatly improves the anti-rust function;

5.LED advertising screen high-performance "ground effect" scheme circuit board layout design, can effectively control the voltage peak overshoot, maximize the life of lamp tubes, chips and other components;It adopts the general power supply and signal interface mode, and is not affected by any region, environment, control system and other factors. It can easily carry out the backup storage, connection and installation of various LED advertising screens.

6. The flatness of the mounting surface of LED advertising screen module shall be controlled at plus or minus 0.2mm, and the flatness of the whole screen shall be good;Led display price

7. The LED advertising screen circuit board adopts the wave soldering process, and has a green oil oxygen barrier layer, which prevents moisture and oxidation of the circuit and improves the service life;

8. The front side of LED advertising screen is equipped with special heat-conducting pouring and sealing silicone gel, and the back side is protected by spray of three anti-paint, which is double waterproof protection, so that the product has stronger weather resistance and faster heat dissipation;The unique drainage hole design can reduce the damage of the module caused by the steel structure defect caused by water intake, improve the self-protection ability of the module, and further guarantee the service life of the display screen.

9. Compared with outdoor direct-insert full-color products, the outdoor appearance paste series products are lighter and lighter, which brings convenience to assembly, transportation and later maintenance, saving time and effort.

10. Because the design structure of LED advertising screen is three-in-one, the three chips are very close to each other, so the red, green and blue light mixing effect is better than the straight oval LED screen, especially suitable for close viewing.

11.LED advertising screen due to the three-in-one design structure, full-color SMD size is small, so the luminous area is small, black area is large, improve the contrast of LED advertising screen.
