1. Project Profile
1.1 Project Background
This section adopts structured classification to clearly display the basic information and core renovation requirements of the venue.
1.1.1 Basic Project Information
Project Location: Laoshan Campus, Ocean University of China (National 985/211 Key University, Qingdao)
The multi-functional gymnasium covers a land area of 31,000 m², with a total construction area of 37,779.6 m² and a 24,051.6 m² competition hall equipped with 4,152 fixed seats. Serving professional sports competitions, campus teaching, daily fitness, conferences and large-scale events, the venue adopted aging metal halide lamps that had operated for 15 years with severe performance degradation and hidden risks. CPS Lighting completed the overall LED lighting renovation to renew the outdated system and upgrade the venue’s professional lighting standards.
1.1.2 Core Renovation Requirements
Safety Upgrade: Eliminate aging lamp hazards and reduce building roof structural load
Construction Standard: Adopt 1:1 original position replacement to avoid venue transformation damage
Energy-saving Target: Effectively reduce overall lighting power consumption
Standard Upgrade: Upgrade lighting level from JGJ Grade IV to Grade V (Major International TV Broadcast Standard)
Intelligent Upgrade: Support multi-scene switching to meet the needs of daily training, amateur competitions and high-level professional events
2. Pre & Post Renovation Performance Evaluation
2.1 Pre-construction Pain Points
The old metal halide lighting system had multiple defects that failed to support modern high-standard venue operation:
Equipment Defects: Bulky lamp body, slow startup speed, low luminous efficiency
Energy & Load Problem: High power consumption, excessive overall roof load
Lighting Performance: Severe light attenuation, poor uniformity, uncontrollable glare
Standard Failure: Unable to meet the original Grade IV TV broadcast standard
Safety Risk: Long-term aging of equipment brings potential safety hazards
2.2 Post-construction Data & Effect Comparison
After CPS LED renovation, the venue achieved comprehensive upgrades in safety, energy saving, lighting performance and intelligence. The core data comparison is as follows:
3. Design Standard: JGJ & National Specification
3.1 Compliance Specifications
The whole project is strictly designed, tested and accepted based on two national authoritative standards:
JGJ 153-2016: Standard for Lighting Design and Test of Sports Venues
