Abstract
There is disclosed a light diffusing device that includes a transparent base layer with a diffuser layer over it. The diffuser layer is formed of multiple light diffusing elements. These elements are preferably diamond-like in shape and are substantially in alignment. The diffusing elements, arranged in this manner serve to uniformly diffuse light, typically as emitted from fluorescent tubes, to which the device or devices is/are typically attached, such that areas of greater intensity, known as “hot spots” and areas of lesser intensity, known as “shadows” are eliminated, and viewers have difficulty determining the direction of the fluorescent tubes. The device can be flat, and when combined with adhesive forms a tape, that may include a backing member, inert to the adhesive, for storage. Tubular devices are also permissible.
