8 LED display screens on the Asian Games
In the air show, the actors clung to the sails and flew up and down. Many viewers were worried about "Will they break the screen?" Wang Jun, the manager of the sail screen project, said: "The sail screen should be able to withstand It is the most basic requirement for a person to fly up and hit it without deformation or damage."
According to reports, 8 sail screens, although far from the view of 8 tight wind-tight sails, the actual is hollow structure, there are nearly 8 cm gap between each two horizontal LED light source, for the actor to grasp, step Foot borrowing power. Moreover, when the sail screen is raised, in order to be more like a sail, it is not completely straightened, but has undulating undulations, which is also convenient for the actors to step on the borrowing power.
Since the idea is derived from the sails, the folding and lifting function is indispensable. It is understood that this technology is the world's first.
Each sail screen is made up of hundreds of 1.2-meter square lighting units, each of which has a grid-like structure. The single grating is only 2.5 cm × 2.5 cm thick, but it can withstand the weight of an adult.
In order to meet the design strength requirements of the grating, the outer shell of the grating is made of aerospace aluminum-magnesium alloy, and the eight sail panels consume a total of 64 tons of alloy, which is enough to make the outer casing of two Boeing 737 aircraft.
After the Asian Games, 8 sail screens will be permanently retained, becoming a new attraction in the new central axis of Guangzhou.Dongguan Yangyue Metal Technology Co., Ltd , https://www.yyconnector.com
