Slat Ray Tracing Diagram
A section of the patented LightLouver reflective slat shows the path of sunlight from different solar altitude angles. All sun above a 5 degree altitude angle is redirected upward onto the ceiling of the daylit space, providing ambient lighting and eliminating direct sunlight on work surfaces.
Image of "daylight glazing" with LightLouver units installed and "vision glazing" below it show sunlight being reflected upward by the LightLouver units in the Caltrans District 3 Headquarters in Marysville, California.
