Xuanwu Lake in Nanjing is a national key park and a national-level water conservancy scenic area. With the ancient names of Sangpo and Houhu, it is one of the three famous lakes in the south of the Yangtze River, one of the largest imperial garden lakes in China. It was also the national archives for preserving imperial census registers during the Ming Dynasty in Nanjing, and is known as the "Pearl of Jinling".  

As one of the largest imperial garden lakes in China, Xuanwu Lake can trace its history back to the Pre-Qin period. Having gone through the misty rain of six dynasties, it has witnessed the rise and fall of countless dynasties. The surface of Xuanwu Lake is broad and expansive, with rippling blue waves. There are five islets (Huanzhou Islet, Yingzhou Islet, Lingzhou Islet, Liangzhou Islet, and Cuizhou Islet) scattered in the lake, which are connected by bridges, forming a beautiful picture scroll. In spring, the cherry blossoms are in full bloom; in summer, the fragrance of lotus flowers fills the air; in autumn, the maple leaves are as red as fire; and in winter, the snow scene is like a painting. With the change of the four seasons, Xuanwu Lake always has different sceneries waiting for tourists to explore. Surrounded by mountains and water with rippling blue waves, it is not only an excellent place for leisure and entertainment but also a must-visit destination for both domestic and foreign tourists to explore history and culture and enjoy the natural beauty.

Just this summer vacation, the Xuanwu Lake Scenic Area launched a brand-new night tour project - water screen projection. As a modern art form that integrates sound, light, electricity and water, with its unique visual impact and shock, it has become a popular project in the cultural and tourism industry in recent years.

On the ancient yet vibrant land of Xuanwu Lake, the water screen projection show not only presents the peerless elegance of Jinling, the ancient capital, but also perfectly integrates modern technology with traditional culture, bringing visitors a stunning visual experience. By using projection technology, three-dimensional images of mythical beasts such as the Azure Dragon, the White Tiger, the Vermilion Bird, and the Black Tortoise, as well as scenes like a hundred flowers welcoming spring, are presented in the air (on the water screen), giving visitors a strong sense of space and visual shock. In addition, the scenic area has also launched activities such as the Hanfu Festival in combination with the Hanfu culture, further enriching the cultural experience of tourists.

In this water screen projection show, Diheng's Lyra DU21K laser engineering projector is undoubtedly the bridge connecting light and shadow with culture. Relying on its excellent performance and stable operation, the Diheng Lyra DU21K provides solid support for the entire show. The DU21K is positioned as a professional engineering projector. It adopts a more stable optical engine architecture design and a telecentric optical architecture design, enabling excellent performance in terms of color uniformity and brightness uniformity of the projected image. Its central brightness reaches up to 21,000 lumens. Even in complex outdoor lighting environments, it can present clear and stable projection effects. This feature is crucial for the water screen projection show at Xuanwu Lake, as it needs to ensure that a picture with sufficient brightness and clarity is formed on the vast lake surface to attract tourists and create a stunning visual impact. In terms of image quality performance, the DU21K also spares no effort. It is equipped with an advanced 0.96-inch DMD chip, which can carry more light flux compared to traditional chips, making the projected image more delicate and vivid. At the same time, it supports 4K signal input and 120Hz high refresh rate input, ensuring that every frame of the image is clear and smooth. These technical features enable the DU21K to accurately reproduce every detail on the water screen. Whether it is the mythical beasts from the legends of Xuanwu Lake or the layers of the scenery, everything is clearly visible. In addition, the DU21K is also equipped with a complete interface system, including various interfaces such as 3G-SDI, DP, and HDBaseT, supporting the access and transmission of multiple signal sources. In particular, the standard HDBaseT interface can achieve long-distance transmission of more than 100 meters, which is especially important for a vast outdoor venue like Xuanwu Lake. It ensures the stable transmission of signals and the synchronous display of images, bringing a more coherent and stunning visual experience to tourists. The water screen projection show at Xuanwu Lake not only brings a brand-new visual experience to tourists but also has become a new business card for Nanjing's cultural and tourism industry. It showcases the unique charm of Nanjing as a famous historical and cultural city and also highlights the important role of light and shadow technology in cultural inheritance and innovation.
