Project Description

The Yellow Crane Tower situates on the ridge of the Snake Mountain near the Yangtze River in Wuhan City. It was first built in 223 during the Three Kingdoms era, and afterwards known as one of “the three famous towers in the south of the Yangtze River”, which refers to the Yueyang Tower in Hunan, the Pavilion of Prince Teng and the Yellow Crane Tower. From ancient to modern times, millions of scholars have toured here, and written down beautiful poetry works that enjoy great popularity. It gives the tower a strong sense of cultural deposit. And now, it is a 5A-level tourist attraction in China.

The Tower wanted to achieve comprehensive lighting control for the entire indoor lighting, and balance exterior ambient light with interior light. HDL designed a solution to address the Tower’s concerns. The intelligent system will automatically adjust the brightness of lights in the Tower according to the exterior ambient light. Meanwhile, quantitative control on brightness is also available to provide needed luminous flux. Various lighting elements are perfectly integrated by changing the brightness of lights and switching between scenes subtly.


Three scenes of lighting are programmed in the system:

  • Night Mode – That is the Full lighting Mode, which provides adequate lighting to visitors for sight-seeing and safety needs.
  • Day Mode – This scene is designed to solve the problem of uneven brightness, which is caused by excessive sun light in the day time and makes people’s eyes uncomfortable while adapting to less lighten environment.
  • Replenishing Mode – The system will enhance lighting to keep constant brightness while the sun light is inadequate in the day time.

The HDL Yellow Crane Tower intelligent lighting project is a manifestation of energy saving. Yet it’s also a perfect combination of ancient design and high-end modern technologies.
