摘要

We propose and demonstrate the use of Engineered Diffusers~(TM) for control and distribution of LED light for general lighting applications. These diffusers are based on refractive microstructures and enable the efficient use of energy by controlling light propagation and directing it to specific regions of space. The microstructures are generally microlens-based arrays with each microlens elements individually designed to meet the desired scatter properties. In addition to light control, Engineered Diffusers~(TM) can be used for RGB mixing to produce white light with variable color temperature, depending on the RGB content of the source. A single Engineered Diffuser~(TM) component can be used for efficient color mixing and illumination control. We also discuss the fabrication of Engineered Diffusers~(TM) by means of a single-point laserwriting method with capability to manufacture the deep refractive structures needed for LED beam shaping.
