"Details that should be paid attention to in the installation of electronic screen LED modules" LED modules are the core components of electronic screens. The most critical thing when assembling electronic screens is the flatness and waterproof requirements of LED modules. There are many structures for assembling LED modules. Indoor A frame structure can be used for a small area, a simple box structure can be used for a large area, and a box structure must be used when assembling LED modules for outdoor screens, and waterproof rubber pads must be installed and locked with screws to achieve waterproofing effect. The LED module is square and regular. When assembling, install it from the middle first, and then expand to the two sides. This operation is to prevent the LED module from leaning to the left or right. Only when assembling the whole screen can the LED module be guaranteed. Group flatness, there will be no gaps in the middle. Below we introduce some details of the LED module assembly process in detail: 1. The LED module uses low-voltage input, so it is absolutely impossible to directly connect to 220V without going through the power supply, otherwise the whole LED module will be burned.
2. For LED modules that have not been waterproofed, when they are installed in the box, rainwater should be prevented from entering the box, so waterproof rubber pads must be installed. 3. In order to prevent the connecting wire from falling off easily from the wire holder, the wire holder is designed with a barb. If it is inconvenient to insert, it should be withdrawn and reinserted. It must be confirmed that the wire connecting the LED module is firmly inserted, otherwise it will cause it to fall off in the future.
4. The number of power port outlet modules in series should not exceed 8 groups, otherwise the tail module will reduce the brightness of the LED module due to voltage attenuation. Although forming a loop can avoid attenuation, but too many LED modules should not be connected. 5. The distance between LED modules should be within 1mm. If the gap is too large, the whole screen will be uneven.
6. When the power cord is connected to the cabinet, it must first be connected to the corresponding four or three groups of LED modules through four-point or three-point wires. After the power cord enters the cabinet, a larger knot should be tied to prevent other The power socket of the LED module was torn off by force from the outside. 7. The output voltage of the switching power supply is adjusted according to the characteristics of the LED module. Please do not rotate the voltage adjustment button arbitrarily during use. 8. When installing modules in the box, use three-point and four-point lines as much as possible. When connecting lines, try to make the entire word or the box form a loop, or multiple loops, that is, use red and black power lines to connect each The modules at the end of the strokes are connected according to the positive and negative poles.
9. There are positive and negative poles in the LED module. When installing, pay attention to the positive and negative poles of the power port wiring. If the positive and negative connections are reversed, the LED module will not emit light and will not damage the LED module. Just replace it. Can be normal. 10. Special switching power supply for LED. The power supply can only be moisture-proof, not waterproof, so waterproof measures must be taken when the power supply is installed externally.
11. The LED modules all use low-voltage input, and the power supply is required to be installed within 10 meters of the LED module. If the wire is long, there will be a voltage drop, which will cause inconsistencies in the brightness of the modules closest to the power supply and the farthest modules. 12. The length of the single branch line is 12~m and 15~m respectively, according to the actual use. 13. Do not push, squeeze or press the device on the LED module during installation, so as not to cause damage to the device and affect the overall effect.
As LED electronic screens are more and more widely used, consumers usually ask LED module manufacturers to help install them when purchasing LED electronic screens. Therefore, LED electronic screen installation is a compulsory subject for LED technicians. Although for experienced technicians, the installation of LED electronic screens can be said to be familiar with the road, but for some technicians who are new to LED electronic screens, it is often easy to overlook some places when installing LED electronic screens, resulting in unnecessary There was a problem.
