Summary

Initially, based on directional elements that included clear acrylic plastic rods and fiber optic cables, the authors qualitatively evaluated conceptual designs that incorporate the refraction and diffusion characteristics of the acrylic plastic rods, combined with a reflective element to redirect light upwards. Then, using a miniblind as a model, they explored a fabric design with a Z-pleat cross section and a variable-pitch reflecting tape attached to a fabric substrate. This led to a composite with a round fiber cross section, an aspect ratio of 1.5 to 1, and a specular reflecting tape. The exploratory design was refined by determining the effects on the transmittance distribution of variations in pleat scale, reflecting tape tilt angle, and shade orientation.
