In the world of outdoor lighting, the resilience and reliability of fixtures have always been top priorities for both designers and users. Let’s dive into how waterproof breathable valves play a crucial role in outdoor lighting fixtures and how they save these fixtures from harsh environmental conditions through a real-world example.

Case Background 

A park by the sea in Xiamen, an open park that suffers from sea breezes and rain due to its location, had frequent malfunctions in its landscape lighting fixtures before the installation of waterproof breathable valves. This severely impacted the park’s night lighting and the public’s enjoyment.

Problem Analysis 

The park’s lighting fixtures faced several issues:

1. Internal short circuits in the luminaires, causing them to fail to function properly.
2. Severe internal corrosion in the luminaires, reducing the lifespan of the light source.
3. Deformation of the luminaire housing due to pressure differences inside and out, affecting its appearance and usage.

Solution 

To tackle these issues, the park’s management chose to install waterproof breathable valves in the luminaires. Here’s how these valves made a difference:

1. Waterproofing: The breathable valves prevented water ingress even under constant sea breezes and rain, keeping the fixture interiors dry.
2. Pressure Balance: By equalizing internal and external pressures, the valves prevented housing deformation, maintaining structural integrity in extreme weather.
3. Condensation Prevention: The valves’ moisture exhaust capability prevented internal condensation, allowing the light source and circuit board to operate reliably and last longer.
4. Real-World Impact: Post-installation, the park saw a significant drop in fixture failures and a 70% reduction in maintenance costs. Nighttime lighting quality improved, enhancing public satisfaction.
