Development of a light system using woven optical fiber

EFI Lighting, a subsidiary of automotive supplier EFI Automotive, has asked PISEO to support the industrial development of large luminous surfaces made from woven optical fibers.The high performance requirements (luminance and uniformity control) required the development of specific LED modules and optical couplers for each purpose.
