Seekway CM20 Mesh Light transforms Yeongda Bridge in South Korea into a stunning nighttime landmark. With ultra-high transparency, lightweight wind-resistant design, and vibrant energy-efficient LEDs, it creates a dynamic light canvas without obstructing views or compromising safety.
A New Nighttime Identity for Yeongda Bridge
In the urban fabric of South Korea, Yeongda Bridge is more than just a traffic artery carrying vehicles across the water. It is a landmark waiting to shine after dark. To give this bridge a fresh visual language and cultural tourism value, the project team chose Seekway's CM20 Mesh Light. With its high transparency, lightweight structure, and energy-efficient bright LEDs, this product has successfully turned Yeongda Bridge into a dazzling nighttime destination where light and shadow dance.
Why Bridge Lighting Is Different
Bridge lighting is not the same as ordinary building facade lighting. It faces three major natural constraints:
Wind load challenges: Bridges are suspended in the air with strong winds. Traditional heavy lighting fixtures increase structural burden and are prone to falling.
Visual obstruction: If fixtures are too dense or non-transparent, they can interfere with drivers' ability to see the road and surrounding traffic, creating safety hazards.
What Yeongda Bridge needs is a dynamic canvas that integrates into the structure, lets wind pass through, and remains durable over time. The Seekway CM20 Mesh Light is designed exactly for such scenarios. Its core advantages perfectly match the needs of Yeongda Bridge.
High Transparency: See-Through Design That Preserves Views
The CM20 Mesh Light's mesh structure offers very high transparency, based on its pixel pitch and dot size design. With multiple pixel pitch options ranging from 50mm to 100mm, the fixture barely changes the original visual openness of the bridge's guardrails or cable areas. During the day, it becomes invisible within the structure. At night, it displays brilliant content — no blocked views, only added beauty.
Lightweight and Wind-Resistant: Built for Bridges
The CM20 adopts a modular grid structure that allows wind to pass through freely, providing excellent wind resistance. Compared to traditional light boxes or LED displays of the same area, the wind resistance of CM20 is significantly lower. This ensures that Yeongda Bridge remains stable even in harsh weather conditions.
Energy-Efficient Yet Bright
Each pixel consumes only 0.6W of power, yet uses 3535 SMD RGB/RGBW LEDs with a beam angle of ≥120° — bright enough to overcome ambient light on the bridge. Combined with 16-bit grayscale and 8K refresh rate, dynamic videos and gradient color transitions are extremely smooth.
Built to Last in All Seasons
The housing is made of high and low temperature resistant flame retardant PVC, with FR-4 PCB and IP67 ingress protection (temporarily submersible). Operating temperature ranges from -30°C to 70°C, with a service life of >80,000 hours. South Korea has cold winters and humid, rainy summers, yet the CM20 runs stably every day, significantly reducing long-term maintenance costs for Yeongda Bridge.
Flexible and Customizable
The CM20 supports SPI control mode and can be customized into different shapes and sizes for creative installations along the bridge's curves. In addition, each power supply can handle up to 16 units on one route, making wiring simple and clean.
Its customizable pixel pitch (50mm–100mm) and RGBW version meet different needs — from large text viewed from afar to detailed images viewed up close.
More Than a Light: A Medium of Art and Engineering
The Seekway CM20 Mesh Light is more than just a luminaire. It is a medium that blends engineering aesthetics with digital art. On Yeongda Bridge in South Korea, it proves how technology can poetically illuminate the structure of a city with transparency, lightness, strength, and brilliance.
If you are planning a lighting upgrade for a bridge, building, or public space, take Yeongda Bridge as a reference. Let the CM20 Mesh Light be your brush of light, painting an unforgettable landmark on the night canvas.
