In the heart of Rizhao, Shandong Province, a brand-new cultural landmark, the Rizhao Youth and Women and Children Activity Center, has emerged. This major provincial-level project, with a total construction area of approximately 85,000 square meters, is not only a playground for youth, women, and children, but also a stunning addition to the city’s landscape with its dazzling nightscape.


The core of the project’s lighting design is a massive “light screen” created on the east and north facades of the building. Using an intelligent control system, it achieves subtle changes in color, motion, and grayscale. During weekdays, it creates poetic scenes such as “sunrise in the east” and “the four seasons,” while activating a dedicated “holiday mode” during holidays. This places extremely high demands on the power supply that powers it.
DONE, with a deep understanding of the project’s needs, provided the DL-350H-RAB semi-potted rainproof power supply, designed specifically for harsh outdoor environments. This product combines reliability, safety, and intelligence, perfectly meeting the project’s diverse goals of highlighting the nightscape and creating a festive atmosphere while also balancing energy conservation and consumption reduction.

This high-performance, rainproof power supply is designed for outdoor lighting and complex environments. This series features multiple protections, including short circuit, overtemperature, overvoltage, and overload protection, and a built-in 4-4kV high-level lightning protection mechanism, effectively enhancing system stability and durability in harsh weather conditions. Its semi-potted, rainproof structure ensures excellent heat dissipation while offering excellent moisture and rain resistance, perfectly meeting the stringent requirements for power supply equipment in outdoor lighting projects.
Furthermore, this power supply complies with EMC EN55035/55032 conducted and radiated emissions standards, effectively suppressing electromagnetic interference and ensuring the lighting system does not affect surrounding electronic equipment during long-term operation, providing green and clean power support for the youth center. Whether playing dynamic images on weekdays or featuring special lighting modes during holidays, DONE power supplies utilize precise power control to enable the lighting system to smoothly transition between colors, grayscale, and dynamic effects, enhancing the visual experience while also reducing energy consumption.

Whether in the tranquil late-night mode or the cheerful holiday animations, DONE power supplies, with their silent and stable support, enable the art of light and shadow to be perfectly presented. This not only adds striking charm to the streets but also allows citizens to experience the dazzling night scene where modern technology blends with urban culture from a distance.
Driven by technological innovation and guided by user needs, DONE power supplies bring the power of smart energy to every city and every project. Behind the dazzling lights of the Rizhao Youth Center lies a commitment to quality and a pursuit of innovation, a vivid example of the DONE power supply’s resonance with urban development.
