Underground Commercial Complex Lighting and Spatial Quality Enhancement Project：
This project involved the renovation of an urban underground shopping street. To address the challenges of natural light absence, limited ceiling height, and high pedestrian density, our customized LED lighting and UV disinfection integrated system was implemented. We designed embedded anti-glare linear LED strips combined with adjustable color temperature downlights, achieving an average illuminance of 300lx with a color rendering index (Ra) ≥ 92 in a constrained 3.2-meter ceiling height environment. Simultaneously, 275nm UVC LED modules integrated within ventilation ducts enabled dynamic air disinfection, with testing confirming a sustained pathogen inactivation rate exceeding 99.6%.
Utilizing an intelligent lighting control system, the setup automatically switches lighting scenes based on business hours, achieving 65% overall energy savings. After implementation, average customer dwell time increased by 28%, and merchant satisfaction rose by 41%, successfully transforming a conventional underground space into a safe, comfortable, and modern commercial environment.
