The Tubular Daylighting/Skylight System capture natural light through the outdoor Dome(light collector) without electricity. After being efficiently reflected and transferred by the tube, the diffuser can evenly deliver natural light into the room. From sunrise to sunset, even on cloudy or rainy days, this system brings in sufficient daylight inside. Suntube tubular daylighting system disperse the purest sunlight with optimal color rendition.

The integrated tubular daylight + ventilation system is an energy-free system in which a tubular daylighting system and a natural ventilation system are combined. Not only does it transmit natural light to the interior, but it also meets the needs for indoor natural ventilation. (Patent No.: ZL 2014 2 0745251.8)
