Principle of light tube daylighting
Capture natural light
The roof skylight efficiently harvests sunlight. Made with high-transparency, impact-resistant acrylic that offers ≥92% light transmission while filtering harmful UV rays.
High-Reflectivity Transmission
High-purity aluminum mirror-finish reflective duct with reflectivity ≥99%, ensuring minimal light loss over long-distance transmission.
Indoor diffusion
The diffuser plate with a specialized optical design features a 120° diffusion angle that evenly and softly distributes light to every corner of the room.
Principle of Solar-Powered Ventilation Fan
Solar Power
High-efficiency solar panels convert sunlight into electricity without an external power source, enabling truly zero-electricity-cost operation.
Smart Temperature Control
Built-in temperature sensor automatically starts when room temperature reaches the set threshold and stops when it drops.
Air circulation
Brushless motor drives the fan blades to efficiently expel indoor hot air and humidity while introducing fresh air.
Featured Application Cases
Real-world engineering projects demonstrate the product's exceptional performance across diverse scenarios.
