Diffuse illumination systems and methods

摘要

The systems and methods disclosed herein relate to sources of diffuse illumination for providing substantially uniform illumination to a surface. The diffuse illumination arises from varying the diffusion angle of light generated by an LED system. To vary the diffusion angle, a translucent member is placed between the LED system and the surface. Light emitted from the LED system across the translucent member can subsequently can uniformly cover the surface.
