In the world of professional sports, lighting is not just about visibility; it's about performance, broadcasting standards, and spectator experience. For lighting engineers designing systems for large venues, the biggest challenge is delivering high-intensity light from high masts (often 30m to 50m high) down to the pitch without losing energy.
This is where the precision of a narrow beam LED lens becomes the deciding factor. Asahi Optics specializes in manufacturing high-efficiency optical solutions designed specifically to conquer distance.
What is a Narrow Beam LED Lens?
A narrow beam LED lens typically refers to an optic with a beam angle of less than 15 degrees (often 3°, 5°, 8°, or 10°). Unlike wide floodlights that scatter light, these lenses are engineered to collimate light rays into a tight, focused beam.
This creates a powerful narrow spot effect. By concentrating the luminous flux into a small area, we dramatically increase the Center Beam Candlepower (CBCP). This allows the light to "punch" through the darkness and reach the ground with sufficient lux levels, even when mounted on extremely high poles.
The Critical Role of the Stadium Lens
Designing football stadium lighting is one of the most complex tasks in optical engineering. The lighting must meet strict uniformity standards (often required for 4K TV broadcasting) while adhering to strict energy regulations.
Using a generic lens often leads to light pollution (spill light) and wasted energy. A specialized stadium lens from Asahi Optics is designed to:
- Maximize Light on the Field: Ensure that 90%+ of the emitted light lands on the playing surface, not the stands or the night sky.
- Control Glare (UGR): A narrow spot beam must be controlled. Our lenses feature specialized surface treatments and anti-glare structures to prevent blinding players (like the goalkeeper looking up) or spectators.
- Ensure Uniformity: Through precise optical design, we eliminate dark spots on the field, ensuring seamless consistency for fast-moving gameplay.
Why Asahi Optics for Your Stadium Projects?
Asahi Optics understands that football stadium lighting projects often require customized solutions. Off-the-shelf lenses may not fit every PCB board or heat sink design.
1. Custom Optical Design
We can customize the beam angle to match your specific pole height and spacing. Whether you need an ultra-narrow 3° beam for a central pitch focus or an asymmetrical beam for perimeter lighting, we can simulate and design it.
2. Durability for Outdoor Environments
Our stadium lenses are manufactured using optical-grade PMMA or PC materials that are UV-stabilized. This is crucial for outdoor stadiums in regions like South America or Europe, ensuring the lenses do not yellow or brittle after years of exposure to harsh sunlight and weather.
3. Precision Mold Manufacturing
A narrow beam LED lens requires incredibly high mold precision. A deviation of just a few microns in the mold can scatter the light and ruin the spotlight effect. Asahi Optics’ in-house mold capabilities ensure that the theoretical simulation perfectly matches the mass-produced reality.
Conclusion
From local training grounds to professional arenas, the quality of the light depends on the quality of the lens. Don't let light spill into the sky. Harness it with Asahi Optics’ precision engineering.
