Integration of UHPC Forms with Lighting Systems: Design Essentials and Practice of Reserved Structures

Reserved structures are the prerequisite for the "seamless symbiosis" of UHPC and lighting. Scientific reservation design ensures the lighting effect without compromising the structural safety or aesthetic presentation of UHPC forms. Qinglong Group has accumulated extensive experience in lighting integration reservations through projects such as the light-transmitting UHPC project at Century Plaza on Nanjing East Road in Shanghai and the auditorium renovation of the American International School of Guangzhou.

#Lighting Installation Method Adaptation: Precisely Reserving Installation Space Reserved structures are designed according to the lighting type (embedded, surface-mounted, or projection-based). Embedded lighting requires grooves or holes to be reserved during UHPC component production, sized 5-10mm larger than the fixture to leave heat dissipation gaps; surface-mounted lighting requires reserved holes for connector installation, with reinforcing ribs added around the holes to ensure load-bearing stability. In the Shanghai Century Plaza project, light guide rod installation holes were reserved in the UHPC wood-effect light-transmitting panels, with 8,000-10,000 precisely reserved holes per square meter, perfectly achieving the artistic light-transmitting effect.

#Wiring and Heat Dissipation Reservations: Balancing Function and Safety Considering the wiring requirements of the lighting system, wiring channels are reserved at component joints with a channel width of no less than 20mm, together with proper waterproof sealing design. For high-power lighting, an independent heat dissipation space is reserved, or a UHPC mix ratio with excellent thermal conductivity is adopted to prevent local overheating from affecting component performance. In the colored UHPC hollow carved panel project at the Nanning Liyuan Hotel, reserved ventilation heat dissipation grooves and concealed wiring channels ensure the long-term stable operation of the lighting system.

#Structural Strength Compatibility: Balancing Aesthetics and Safety Lighting reservation structures must not weaken the mechanical performance of UHPC forms. Qinglong uses finite element simulation to analyze stress distribution at reserved locations, applying fiber densification technology around holes and grooves to enhance strength. For complex forms such as double-curved surfaces, reservation structures are integrated with the component's load-bearing reinforcement in the design, meeting lighting installation requirements while ensuring structural integrity. In the Changsha Meixi Lake commercial space project, this design achieved the perfect integration of ultra-thin UHPC components with the lighting system, with components only 4mm thick still maintaining good stability.

The integration of UHPC forms with lighting systems hinges on the forward-looking design of reservation structures. With its detailed design and structural calculation capabilities, Qinglong ensures that every reservation precisely matches the lighting requirements, achieving dual enhancement of both aesthetic effect and practical function.
