Lighting Products and Fixtures Design Nantong Window Cultural Center by Tongji Architectural Design (Group) Co., Ltd The lighting design principle continues the architectural concept. Facade lighting on the waterside of the building is combined with the characteristics of architectural function and form. The other facade of the building is a three-dimensional folding "feather" shaped perforated aluminum curtain wall system. Linear lamps with 4000K are installed inside the triangular folder curtain wall to illuminate the triangular bottom and reflect into the entire curtain wall cavity. Through the feather-like perforations, it looks like a lantern that shines through the whole body.
