1. Project Profile
1.1 Project Background
Zhejiang Jinlin Sports Center boasts a total construction area of 36,000 ㎡ with 25,000 spectator seats and a FIFA-certified standard football field. Upgrading this high-profile arena with professional football pitch lighting and high-performance outdoor stadium luminaires was essential to ensure compliance with modern athletic broadcast demands.
1.2 Project Requirements
The original lighting system suffered frequent breakdowns, aged wiring and severe ambient corrosion. The owner required a complete upgrade to efficient LED stadium lights to satisfy the strict FIFA-A HDTV broadcast specification, integrate an intelligent dimming system, and achieve a minimum energy saving rate of over 40% under the JGJ 153 standard.

Key Parameter Explanation：
Horizontal & Vertical Illuminance (Eh/Ev): Essential parameters for top-tier stadium flood lights. Eh ensures even ground brightness; Ev creates a three-dimensional visual effect for athletes and the ball on broadcast cameras.
Illuminance Uniformity U1/U2: Measures consistency with U1=Min/Average and U2=Min/Max. Higher values in the sports lighting fixtures layout eliminate irregular light-and-shade zebra stripes across the pitch.
Glare Rating (GR) / Unified Glare Rating (UGR): Lower GR values avoid sudden visual dazzle for players catching high balls; our targeted anti-glare LED sport lights easily satisfy the professional HDTV requirement of GR≤50.
CRI / High Color Rendering Index (Ra) & TLCI: Reflects color authenticity; high-end arena lighting needs Ra≥90 and high Television Lighting Consistency Index to restore the real tones of athletes’ skin and turf.
Flicker-free Lighting: Critical for slow-motion replay; utilizing a high-frequency driver restricts flicker within 0.5% for 4K/8K cameras.
4. Customized Full-package Solution by CPS Lighting
As a professional sports lighting manufacturer, CPS Lighting delivered a fully customized lighting solution covering structural safety calculations through advanced intelligent control system deployment:
Typhoon-resistant Structural Engineering: Independent wind load calculations and structural safety certification enable heavy-duty high mast lighting for the stadium to resist Category 16 typhoons.
Higher Commissioning Efficiency: Utilizing advanced DIALux lighting simulation and AGi32 lighting simulation achieved centimeter-level accurate lamp layout; commissioning duration was cut from 20 days down to 4 days, lifting overall installation efficiency by 80%.
Intelligent Central Control: Supports standard DMX512 / DALI control for seamless one-touch mode switching among HD match broadcast, professional training, energy-saving mode, and custom light shows.
Anti-corrosion Performance: Fixtures featuring optimized die-cast aluminum heat sinks passed 1000-hour salt spray certification and achieved an IP66/IP67 waterproof dustproof rating.
Flicker-free HD Broadcast Lighting: High-frequency constant-current drivers ensure complete flicker-free lighting (under 0.5%), fully compatible with 4K/8K Ultra HD broadcast standards for slow-motion playback.
Low-glare Optimization: Advanced TIR internal reflection optical structures restrict glare output (GR < 40) for enhanced player comfort.
Remarkable Energy Efficiency: Utilizing fixtures with high luminous efficacy reduced total power from original 716.8kW to 367.2kW, delivering an actual energy saving rate of 49% with lower overall power consumption.
