What should I prepare before installing a full-color LED display? _Outdoor Full Color LED Display|Indoor LED Display
There are generally two types of full-color LED display installations, one indoor and one outdoor. Indoor LED display is relatively simple to install, mainly including hoisting, ordinary hanging, bracket hanging, inlaid and seated. Initially, the early survey is important for comparison. It is necessary to prove the design of the screen body according to the on-site construction situation. The proper integration of the assembly site and the screen body is the first step of the full-color LED display assembly process. The need for full-color LED display to display content, site space conditions, full-color LED display unit template size (indoor screen) or pixel size (outdoor screen), the wrapping must be calculated. The power consumption of the LED display is divided into average power consumption and maximum power consumption. Average power consumption, also known as working power, is the actual power consumption in normal times. The maximum power consumption is the power consumption in extreme situations such as startup or full lighting. The maximum power consumption is an element that must be considered for AC power supply (wire diameter, switch, etc.). The average power consumption is generally 1 of the maximum power consumption. /3. The LED display is a large-scale precision electronic device. For safe use and operable work, the AC220V power input terminal or the AC220V power input terminal of the computer connected to it must be grounded. Full-color LED display steel frame design, usually within 3-5 days after signing the contract, the LED display assembly engineer will prove the on-site situation and the actual situation of the LED display to design the steel frame structure and deliver it to the upper constructor and the construction party. Might as well get the steel frame structure drawing (CAD drawing) later, the left certificate drawing to purchase the relevant material skills, and plan the steel structure construction. The full-color LED display is installed outdoors, often exposed to the sun and rain, and the working environment is harsh. Electronic equipment getting wet or severely damp can cause short circuits or even fire, cause failures or even fires, and cause losses; LED display screens may be attacked by strong electricity and magnetism caused by lightning; environmental temperature changes greatly. When the LED display screen is working, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally; the audience is wide and the viewing distance is long. , Wide field of view requirements; large changes in ambient light, especially the possibility of direct sunlight. In response to the above special requirements, outdoor full-color LED displays need to do the following: the screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and once the accumulation of water occurs, it can be discharged smoothly; Install lightning protection devices on LED display screens and buildings; install ventilation equipment to cool down so that the internal temperature of the screen is between -10℃ and 40℃. An axial flow fan is installed on the top of the back of the screen to dissipate heat. How many axial flow fans are used according to the size of the screen; The outer packaging of the full-color LED display media of Huaze Optoelectronics is currently the most popular rectangular cylinder with a cover, and it is sealed with silicone. Non-metallic assembly; its appearance is exquisite and beautiful, sturdy and durable, with the 'five-proof' characteristics of protection from direct sunlight, dust, water, high temperature and short circuit. Therefore, you must be cautious when installing outdoor full-color LED displays, and must be waterproof, and if you accidentally leak water, you must do a good job of drainage! Must carry out lightning protection devices, and must also do regular inspections and regular dust removal in the later period. Outdoor full-color LED display has a large area, and the design of steel structure should consider many factors such as foundation, wind load, magnitude, waterproof, dustproof, ambient temperature, lightning protection and so on. Auxiliary equipment such as power distribution cabinets, air conditioners, axial fans, lighting, etc. should be placed in the steel structure, as well as maintenance facilities such as horse tracks and ladders. The entire outdoor screen structure must meet the protection level below IP65.
