Abstract
A light source module includes an array of illumination elements and a light diffusing material. The light source module is configured to receive a control signal for adjusting diffusion of light emitted from the light source module and in response adjust the amount of diffusion of light emitted from the light source module. A light source module may include a segmented light diffusing material where each segment is associated with an illumination element. And individual segments may have light diffusing properties that are different than other segments of the light diffusing material. Some illumination elements may emit light of a different color spectrum than other illumination elements, and a light diffusing material may scatter the different colored light to illuminate a scene with combinations of light of different colors. A light source module may be embedded in a mobile computing device.
