Soletu daylighting systems use its unique combination of breakthrough patented technologies, designs and patented materials to capture as much daylight as possible, naturally illuminating any indoor space. Solatube's product technology transcended the limits of physics and invented the "light pipe daylighting system." Through a complex optical system, Solatube International invented the patented technology "Light Bender 3000" and "Light Catcher", which greatly increased the effective daylight collection area (EDCS); the patented material "UV" was applied in the daylighting cap. Protective agent", which for the first time shields all ultraviolet rays in the solar spectrum, thereby not only protecting the skin health of indoor personnel but also ensuring that the service life of the light pipe daylight lighting system is the same as that of the building; the "Colorful Unlimited?" reflective material was developed , breaking through the physical limit that the reflectivity can only reach 98, and raising the reflectivity to 99.7 for the first time in the world; creating the "Solatu Dimmer?" control system and "optical diffuser" to control sunlight Stable output is possible. Most importantly, Solatube is the only light output data file in the world that can apply the World Typical Climate Data Year (TMY2) data, allowing hour-by-hour lighting energy saving calculations of 8,760 hours a year for projects anywhere in China. . From now on, experts in the architectural design industry can design daylight lighting fixtures just like they design electric lighting.
