1. Project Profile
1.1 Project Background
This project is a key comprehensive sports landmark, requiring professional indoor gym lighting systems, of Central South University in Changsha, Hunan. Covering 16,000 m² with a total construction area of 27,989 m² and a total investment of 270 million yuan, the venue has been fully completed and officially operational.
It consists of an 8,383-seat multi-functional gymnasium and a 474-seat natatorium, utilizing specialized basketball court lights, badminton court lights and swimming pool fixtures to serve campus sports teaching, student daily fitness, professional competitions and event live broadcasting. The gymnasium supports flexible venue conversion for basketball and badminton events, while the natatorium is equipped with standard constant-temperature pools, covering multiple sports training and competition scenarios.
2. Pre & Post Renovation Performance Evaluation
2.1 Pre-construction Pain Points
The original venue lacked professional sports lighting fixtures, with prominent functional defects: inconsistent lighting for different sports scenarios, severe glare and water reflection in the natatorium, inability to support professional competitions and HD live broadcasting. Meanwhile, traditional lighting featured single working mode, high energy consumption and manual cumbersome management, failing to match the high-standard venue operation demands.
2.2 Post-construction Effect
CPS customized lighting solutions completely solve the above pain points. All venue lighting indicators meet national standards and graded event requirements. It achieves uniform, flicker-free and low-glare lighting for basketball, badminton and swimming scenarios, eliminating shadow and light reflection interference, and fully adapting to professional training and high-level event HD live broadcasting.
Matched with our intelligent dimming system, the venue realizes one-key mode switching, achieving intelligent management and energy-saving operation. The excellent lighting effect has been highly recognized by the school, greatly upgrading the venue’s professional service level.
3. Design Standard: JGJ Sports Lighting Classification
The entire project is designed, configured and debugged in strict accordance with the JGJ 153 standard (JGJ 153-2016 Standard for Lighting Design and Test of Sports Venues), adopting graded lighting design for different functional areas to match daily training, amateur competition and international live broadcast-level event demands.
Grade Ⅱ (Amateur Competition & Professional Training): Applied to amateur basketball & volleyball courts, natatorium main and secondary venues.
Grade Ⅴ (HD TV Live Broadcast for Major National & International Events): Applied to the core professional basketball competition venue, meeting top-level event lighting and live broadcast standards.
All designs strictly control core indicators including illuminance uniformity U1/U2, glare rating (GR), color rendering and flicker suppression, achieving full standard compliance for all scenarios.
