Natural lighting system: "light duct" that allows sunlight to pour into the building.
Material House, Light Duct, Watanabe Pipe, SEDIA SYSTEM
A life filled with pleasant light by incorporating natural light as indoor lighting. Solving the challenges of skylights, with no maintenance required. No electricity needed and UV rays are also cut.
<Features> ■Reduction of daytime power consumption: Key to lighting By utilizing natural light directly for illumination, no electricity is needed. This is particularly effective in areas where lighting is required during the day, with some installations achieving an 80-90% reduction in artificial lighting. ■Maintenance-free: No performance degradation for about 20 years after installation Light ducts that have not undergone maintenance or cleaning for approximately 20 years continue to maintain their performance and emit light. Thorough durability testing and structural innovations have made maintenance-free operation possible. <Applicable Scenes> ■In lower floors of school buildings: A spacious educational environment under natural light The core areas of lower floors, where natural light is difficult to obtain, are one of the cases where light ducts are most effective. This is for creating an educational environment where children can grow freely. ■Renovating skylights to light ducts: Brightness increased sixfold We solved the customer's concern about dark hallways despite having skylights by using light ducts. The results are clear, with brightness increasing by approximately six times, allowing visibility in every corner of the hallway. *For detailed specifications, please download the PDF catalog or feel free to contact us.

basic information
<Shape and Material> ■Minimizing Light Attenuation - High Reflectivity Aluminum Reflective Material The light duct is composed of aluminum reflective material. Its reflectivity is over 95%, which minimizes light attenuation. Furthermore, it contains no resin-based components, so there is no degradation from ultraviolet rays. ■Compatible with Various Duct Shapes With high-precision simulations, we can accommodate various paths while balancing the output light quantity. For detailed design information, please refer to the section below. <Process Until Construction> 1. Consideration of Light Duct Specifications - Image of Light We start by sharing the image of the light with the customer, considering the application and purpose of the light duct, as well as the spatial image. This includes brightening an office, softly glowing as an emergency light, or sunlight filtering through trees at an entrance, among others. - Drawings Indicating Orientation and Duct Path We can accommodate various shapes, including vertical and horizontal types. We will propose duct diameters based on the required light quantity. 2. Simulation and Quotation We will simulate the output of the light duct (unit: lumens). 3. Detailed Consideration 4. Approval of Construction Drawings 5. Fabrication of Light Duct 6. Installation of Light Duct

Detailed information
-
The "Light Duct" is a lighting system that transports natural light through a series of reflections and uses it directly as indoor lighting. The special mirror-finished aluminum material has a reflectivity of over 95% and also cuts ultraviolet rays, making it possible to deliver bright and healthy natural light. It can accommodate and propose various patterns regarding the route, position, and size of the light-emitting sections.
-
Comfort for your children. The comfort of natural light that everyone feels cannot be experienced with artificial lighting. Light ducts provide the comfort of natural light while cutting only ultraviolet rays, offering a gentle lighting solution for both body and mind.
-
Reducing power consumption during the day relies on lighting. Naturally, no electricity is needed to utilize natural light directly for illumination. This is particularly effective in areas that require lighting during the day, with examples of installations that have been able to turn off artificial lights by 80-90%.
-
A light duct that has not undergone maintenance or cleaning for about 20 years is still maintaining its performance and continues to emit light. Thorough durability testing and structural innovations have made maintenance-free operation possible.
-
The light duct is made of aluminum reflective material. The reflectivity is very high at over 95%, minimizing light attenuation. Furthermore, since it does not contain any resin-based components, there is no degradation due to ultraviolet rays at all.
-
By using high-precision simulations, it is possible to accommodate various paths while monitoring the output light quantity and balance.
