High efficiency daylighting structure
First Claim
1. A process for making a daylighting structure, the process comprising the steps of:
- a) providing a planar internally transparent sheet of material having opposing native optical surfacesb) cutting the sheet into elongated parallel bars,c) orienting an assembly of the parallel bars with the native optical surface facing each other and the cut surface forming an upper and lower vertical plane, wherein at least one of the native surface of each bar is an at least partially reflective surface,d) attaching the cut surfaces of the parallel bars to a planar support member on a least one of the upper and lower vertical plane,e) wherein the daylighting structure has a plurality of spaced apart at least partially reflective surfaces.

Abstract
A high efficiency daylight directing structure for application on fenestration deploys closely spaced macroscopic bars of transparent resin to eliminate different forms of glare. The spaced apart surfaces provide for efficient reflection of selective incident light, by TIR or metallic surfaces, via the ultra-smooth native surfaces from a mold or casting process. A close spacing is readily obtained in various attachment methods to boost efficiency. The fabrication method allows selective deposition of absorbing layers, such as by of painting/printing between alternating native optical surface to provide one way transparency at high angles of incidence. The bars are supported on at least one common planar surface by transparent support member with an optical quality adhesive material filling any imperfection in the bars common planar surface that form in fabrication.
