Abstract
The invention relates to an acrylic light diffusing material providing spectral uniformity over the visible light range, defined herein as from 400 to 800 nm. The light diffusing material provides a uniform light transmission for light engines having two or more light sources with different spectral emission peaks. Due to its high hiding performance, the light diffusing material of the invention is especially useful with LED point light sources. The diffusing material contains a transparent polymer matrix and one or more types of diffusing materials, providing an optimal balance of spectral uniformity, light transmission, diffusion, and hiding performance.
