From the industry standard to the leading edge, helping the world we live.
“DOKODEMO HIKARI MADO” (skylight window anywhere you like) sunlight transmission system *
(* Name of optical duct system manufactured with Mirror coat K. Trademark pending in Japan.)
This system incorporates natural light in the duct where the interior is a mirrored surface, and conducts light to locations where it is difficult to place windows using reflection.
Horizontal duct system Vertical duct system
Natural light for bathrooms and toilets on north side
For kitchens and living rooms
Bright staircase using natural light
This system employs highly reflective mirrors to guide natural light from openings in a building's walls and roof to interior spaces. It is an efficient method of utilizing natural energy since once installed it requires no additional resources in order to function.
The Toyota Motors Main Building uses this approach to introduce light to the basement cafeteria via an underground mirror duct.
