In August 2025, the Shanghai Cooperation Organization Summit took place in Tianjin, China. To welcome this prestigious international event, Tianjin launched a city-wide image enhancement initiative, highlighting its nighttime beauty with a series of high-quality light and shadow installations. Appotronics played a key role in this transformation, providing cutting-edge projection solutions that infused the city’s iconic landmarks with a perfect balance of technological sophistication and artistic flair.

Wudadao Clock Tower Light Show

Tianjin’s Wudadao Clock Tower, a newly established landmark in the city, was transformed into an awe-inspiring light show for the summit. Standing at 69.6 meters tall in the heart of the Wudadao Cultural and Tourism District, this British classical-style structure, with its 19 theme clocks, became a focal point of the city’s nightlife. Appotronics deployed a combination of three G Pro series and one S series laser projectors, using state-of-the-art 3D mapping technology to illuminate the clock tower's four facades. The projection seamlessly integrated with the tower’s architectural details, creating a stunning 3D light experience that captivated both locals and visitors. The clock tower now stands as a testament to the city’s artistic vision and technological capabilities.

Li Shun De Hotel Building Light Show

Equally iconic is the Li Shun De Hotel, established in 1863, which is considered a living “fossil” of modern Chinese history. This building, renowned for its British classical Romantic-style corner towers, is a symbol of architectural beauty. Appotronics took great care to preserve the building’s aesthetic while adding a dynamic, modern touch. For this light show, two G Pro series projectors were used to execute a vertical projection plan that wrapped the building in vibrant light and shadow. The projections highlighted the building’s timeless elegance while creating an immersive nighttime experience. This light show meets the “daytime architecture, nighttime light show” demand, ensuring the building’s beauty is visible around the clock, and brings a harmonious blend of tradition and modernity to the cityscape.

The Challenge

The primary challenge for these light shows was to preserve the historical integrity of these iconic buildings while providing modern, immersive projections. Both the Wudadao Clock Tower and Li Shun De Hotel required precise alignment with intricate architectural features. The projection systems needed to deliver exceptional brightness and clarity without compromising the original structure’s visual appeal. Appotronics’ high-performance G Pro and S series projectors, combined with advanced 3D mapping technology, provided the perfect solution, adapting to the various surfaces of the buildings and creating a seamless, stunning light display.

The Breakthrough

For the iconic Wudadao Clock Tower, a newly unveiled landmark in Tianjin, Appotronics deployed a combination of three G Pro series and one S series laser projectors. Using advanced 3D Mapping technology, the projectors illuminated the clock tower’s four facades, aligning seamlessly with the building’s intricate textures and clock face patterns. The result was a captivating 3D light show that brought the tower to life, impressing visitors with its detailed visual effects and dimensional beauty.

The Results

Following the successful light shows for the Shanghai Cooperation Organization Summit, both the Wudadao Clock Tower and Li Shun De Hotel have transitioned to a “permanent illumination” mode, becoming an integral part of Tianjin’s vibrant nightlife. Whether strolling along Wudadao to experience the clock tower’s 3D projections or standing in awe at the changing light patterns on the Li Shun De Hotel, these light shows crafted by Appotronics have enriched the city’s nighttime landscape. Combining cutting-edge technology with cultural heritage, these light installations continue to tell the story of Tianjin’s evolving cityscape, blending warmth and texture to create a rich visual experience for the city's residents and visitors alike.
