The efficient harvesting and transmission of daylight through component systems is only half of the science of good daylighting. The proper diffusion and distribution of the daylight into the occupied space is the more difficult part. Daylight America has been manufacturing our own proprietary and patented lighting diffusers since 1992. One diffuser does not fit all applications and DSI has assembled a wide variety of diffuser designs and optical solutions to supply the right diffuser for each space. Our patented Sun-Point™ diffuser is primarily used in lower ceiling applications and is made to standard grid sizes in 4x4, 2x4 and 2x2 sizes. Higher ceiling and open bay diffuser options include pyramids, hybrid pyramids, shallow trough and flat lenses in a variety of materials and transmittance values. Without adequate diffusion and distribution of the daylight, you cannot reliably schedule electric lighting to be off while maintaining uniform coverage in that space.
