Abstract
A lighting assembly for compact computer devices such as, for example, hand held video games utilizes a light source directed away from the display screen of the compact computer device and a reflective surface selectively positionable over the display screen to intercept and reflect the light emanating from the light source and redirect it toward the display screen. The directing of the light away from the display screen and subsequent reflecting back toward the display screen results in an evenly diffused light being applied to the display screen, while completely eliminating the otherwise experienced hot spots or dark spots common in prior art light assemblies.
