Abstract
An accessory lighting assembly for selectively illuminating user selected areas such as, for example, compact computer devices, books and other desired areas. The light source is directed away from user selected area for illumination and a reflective surface is selectively positionable to intercept the light emanating from the light source and re-direct it toward the user selected area. The directing of the light away from the user selected area for illumination and subsequent reflecting back toward the user selected area results in an evenly diffused light being applied to the user selected area, while completely eliminating the otherwise experienced hot spots or dark spots common in prior art accessory light assemblies.
