<p>A light diffuser unit suitable for use in the path of light emitted from a source to diffuse the emitted light comprises two major surfaces 301a, 301b for transmitting light from one side of the light diffuser unit to the other. A first major surface is convex and a second major surface is not co-planar with the first major surface. The diffuser unit is constructed of a light diffusing material. This lens-like structure creates a uniform distribution of light across the subject side of the diffuser unit.</p> |
