The test of the comprehensive strength. The project required the huge Mona Lisa's background light display to be identical to the computer monitor. The 999 oil paintings and LCD screens that make up Dafen Lisa are fixed with rectangular squares of aluminum grooves. The distance between the box and the edge of the oil painting or display screen is 15 mm. Several LED lights are embedded in the aluminum slot. The light hits the wall, and each of the 999 boxes serves as a unit. The computer can be used to control the switch and the intensity of the light to create the desired effect.
In the process of use, using advanced microcomputer control technology, the internationally widely used DMX-512/1990 standard digital control signal is converted into PWM drive LED, which can select 1~3 output channels, each channel can realize 256 levels of control level. . The light source adopts the company's 3528 series white light products, which makes the LED constant current soft light strip combined with the heat dissipation aluminum structure, that is, the brightness requirement, and also solves the heat dissipation problem. These LED lights floated in the gap between the oil painting background and the 999 Mona Lisa oil paintings, making the huge oil painting a dreamlike effect. In order to achieve the best display effect, the main control equipments are all imported from Germany, and the quality, effect and operability are required to reach the world's first-class water products.
In addition, the R&D department has taken into account the need to help the heat dissipation of the LED lamp. The 6063 aluminum slot is used to assist the heat dissipation, and the glue is used to ensure the dustproof and waterproof to achieve the highest safety factor, ensuring good performance during operation, and eliminating everything as much as possible. The problem with the opportunity. From February 19th, the product design began, and on March 8th, it was not enough for 20 days to complete all the processes including production and testing. After two days of transportation, construction and initial product commissioning began at the Shenzhen Pavilion of the Shanghai World Expo on March 10, and was finally completed on April 18. Due to the tight cycle and the installation and wiring of the site are special and difficult, it will be difficult to maintain once the fault occurs on the construction line.
