1. Introduction: Lighting the Stage for Elite Competition

The Aquatics Centre set new standards for aquatic sports lighting during the 2020 Olympics. Designed to host 15,000 spectators while meeting rigorous athletic and broadcast requirements, its lighting system exemplifies how modern LED technology solves critical challenges:

Athlete visibility in dynamic water environments

4K/HDR broadcast compliance

Glare suppression for swimmers, divers, and judges

Post-Games adaptability for community use

2. Aquatics Centre Lighting Design Principles

2.1 Dual-Area Illumination

Based on FINA/JASF standards and JIS Z9127 sports lighting guidelines.

2.2 Glare Mitigation Tactics

Zero Overhead Fixtures: Eliminated direct light above pools to prevent backstroke glare

Asymmetric Beam Control: Medium-angle optics (40°–60°) with downward-aimed fixtures

VR Simulation: Pre-tested glare perception for divers/judges in virtual environments

2.3 Water-Specific Engineering

Chlorine-resistant IP65 fixtures

Restricted light incidence angles (<55°) to minimize water surface reflections

3. LED System Specifications & Benefits

3.1 Fixture Profile

Type: Waterproof LED floodlights (medium beam)

Output: 106,000 lumens @ 1,010W

Dimming: 5–100% range

Efficacy: 105 lm/W (40% higher than metal halide)

Brand: Ceramiclite Lighting

Sport Light A02

3.2 Operational Advantages

Broadcast Mode: 5,000K CCT, 1,400+ vertical lux for 4K/HDR filming

Energy Savings: 530 MWh/year vs. conventional lighting

Instant On/Off: Critical for timed events and emergency scenarios

4. Broadcast Integration for Global Events

To satisfy Olympic Broadcasting Services (OBS) requirements:

Vertical Illumination: >1,400 lux on all camera-facing surfaces

Uniformity Gradient (UG): <20% variation across dive platforms

Temporal Light Modulation: Eliminated flicker via high-frequency drivers (>5,000 Hz)

5. Transferable Lessons for Aquatic Venues

5.1 Modular Scene Control

Pre-set modes for:

Elite competitions (100% output)

Training (70% output)

Public sessions (50% output)

5.2 Dynamic Glare Management

Fixtures positioned outside athletes’ sightlines during strokes/dives

Real-time dimming adjustments via poolside control panels

5.3 Future-Proof Sustainability

50,000-hour LED lifespan (12+ years at 12h/day)

35% lower HVAC load vs. heat-emitting legacy systems

6. The New Gold Standard

The Aquatics Centre proves that high-performance sports lighting must:

Prioritize athlete visual comfort, enable broadcast excellence, and ensure long-term versatility – all achievable through strategic LED implementation.

Design Takeaways:

Use >100 lm/W LEDs with asymmetric optics

Simulate glare in VR pre-installation

Integrate OBS/FINA standards early

Plan for post-event scaling

For technical standards: Refer to FINA Facility Rules and CIE 169:2005.
