DescriptionApril 18, 2013 - P3 Design Expo, Cornell University - Sunn.jpg |
English: Cornell University – Sunn team member makes adjustment to their Hybrid Lighting demo structure.
One of the characteristics that people look for in a green building is access to natural sunlight. Cornell University students are designing, building and testing a new kind of light fixture that couples fiber optics with LED lights to bring optimal sunlight to interior spaces. It includes an innovative lighting control system to provide light that consistently mimics sunshine, regardless of outside conditions. |
