Abstract
A combined magnifier/lighting apparatus for hand held video games utilizes a directional light source and an angularly adjustable reflective surface disposed opposite the directional source in a frame spaced from the display screen of the hand held device. The use of a directional light source and the adjustable reflective material provides an increased and more diffused lighting effect while eliminating the otherwise experienced hot spots or dark spots common in prior art light assemblies.
