Abstract
An improved lighting apparatus for hand held video games utilizes a directional light source and a curved reflective surface disposed opposite the directional source in a frame positioned proximate to the display screen of the hand held device. The use of a directional light source and the curved 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.
