HEBI, China –  Christie® HS Series 1DLP® laser projectors have brought an iconic clock tower in Hebi to life with spectacular visuals that aim to boost cultural development and elevate its image as a city that exudes elegance and exquisite charm.

Affectionately known as China’s “Big Ben”, the 66-meter-high (217 feet) clock tower was built more than 20 years ago and is one of the most recognizable landmarks of Hebi, a prefecture-level city in northern Henan province known for its rich coal reserves. In a move to soften the city’s industrialized image and inject more vibrancy to Hebi’s administrative, cultural and leisure precinct known as New Century Square, the municipal government commissioned an exciting four-sided projection mapping show on the façade of Hebi Clock Tower. This means that spectators can enjoy amazing visuals regardless of which side of the tower they are facing.

The ambitious project was undertaken by Christie’s trusted partner Zhongqing Yingye Group using a total of 20 Christie DWU2022-HS 1DLP® laser projectors specifically developed for the Chinese market. Achieving 20,6​00 lumens and weighing less than 42 kg (100 lbs.), the Christie DWU2022-HS produces amazing, true-to-life visuals, thanks to the enhanced color accuracy of Christie’s BoldColor Technology and WUXGA resolution.

A spokesperson for Zhongqing Yingye Group said, “We are proud to be involved in this sensational 3D projection mapping light show on all sides of Hebi Clock Tower, which is one of the most prominent contemporary structures in Henan province. We have chosen Christie’s high-brightness DWU2022-HS for this project due to its long-lasting, solid-state illumination in a rugged and compact chassis. At the same time, this projector model is equipped with powerful and easy to use features, and is well suited for demanding, large venue events and applications.”

The 20 DWU2022-HS projectors are divided into four groups, with five projectors used for projections on each side of the clock tower. They are fitted with telephoto lenses, double-stacked and installed in customized enclosures to protect them from inclement weather. Finally, the projectors are strategically positioned at a distance of between 28 and 56 meters (92 and 184 feet) from the clock tower, and the images are meticulously warped and blended to achieve optimal effect.

Zhongqing Yingye Group’s spokesperson added that the show’s high-quality projections have set a new benchmark for large-scale cultural events in China’s north-central region, and the client is very satisfied with the outcome. “Since its official debut, the nightly projection mapping show at New Century Square has become an instant hit with the public, attracting huge crowds to experience vibrant and dynamic images on the tower. Among the highlights is a lifelike golden dragon that seems to break out of the tower, drawing gasps from excited spectators,” he said.

April Qin, sales director for China, Enterprise, Christie, commented, “We are delighted that Zhongqing Yingye Group has accomplished a fascinating projection mapping show on Hebi’s iconic clock tower using the award-winning DWU2022-HS laser projectors to celebrate the city’s development and achievements. With their compact form factor and omnidirectional capabilities, the HS Series is perfect for this highly anticipated nighttime performance.”

Powerful, reliable and cost-effective, the Christie DWU2022-HS is equipped with Christie Twist​ warping and blending engine, as well as optional Christie Mystique​™ automated camera-based alignment tools. It recently won Best Product for the Show Lighting category at the Alighting Awards 2021, and has been used in numerous cultural tourism, performing arts, and entertainment projects across China. These include the Jiangsu Garden Expo Park light show in Nanjing, “Dreaming in Hometown” cultural show in Wuyuan, and the Yellow River Tower light show in Lanzhou.
