The completion and opening of the Liaoyang Road Expressway Tunnel in Qingdao marks a significant step in perfecting the 'four north-south and five east-west expressways' network in the city's eastern urban area. As a global one-stop brand service provider for high-power LED drivers, Done Power provided stable and safe lighting solutions for this key project, ensuring efficient road lighting operation and enhanced safety for high-speed travel.

The Liaoyang Road Expressway Tunnel spans approximately 1.2 kilometers, featuring a six-lane design in both directions. With a clear height of 6.26 meters and a design speed of 60 kilometers per hour, it is not only Qingdao's first urban expressway integrating an underground tunnel with an elevated road, but also the first expressway directly connecting to a highway. This project effectively alleviates traffic congestion along the coastal front and the southern Jiaoning Elevated Road. During off-peak hours, travel time has been reduced from an average of 40 minutes to around 15 minutes, significantly improving traffic efficiency

Facing this key project, Done Power's star product—the MAS-C series dual-circuit dual-CCT + tri-mode dimming and color tuning LED driver—delivers robust support for the roadway lighting in Liaoyang Road Expressway Tunnel. This series features dual-channel complementary output and enables smooth color temperature and brightness adjustment, meeting diverse lighting requirements across varying environments. Compared to traditional power solutions for color tuning, Done Power's MAS-C dual-CCT LED driver series achieves seamless color control with just a single unit, significantly simplifying system architecture and enhancing overall reliability.

Furthermore, the MAS-C series features tunnel-specific negative logic dimming design. In the event of a bus failure (such as a short circuit or disconnection of the dimming wires), the luminaires will maintain maximum brightness, ensuring driving safety. This design safeguards the unique environment and safety requirements within tunnels, providing drivers with a safer and more comfortable driving experience.

Done Power is always committed to providing efficient and reliable lighting solutions for urban infrastructure development. The LED drivers supplied for the Liaoyang Road Expressway Tunnel in Qingdao City not only ensure the safety requirements of road lighting but also contribute to the construction of smart cities. In the future, Done Power will continue to be driven by innovation and committed to quality, providing more high-quality products and services for global urban infrastructure development, supporting the advancement of smart cities, and lighting up the future of more cities.
