Abstract
Two embodiments for an illumination system for a keyboard. One embodiment includes a channel located longitudinally between a visual display screen and its lower keyboard. An illuminator is mounted longitudinally in the channel so that light emitted is directed only to the keyboard and the work surface, avoiding illuminating the screen. The other embodiment includes a free standing keyboard illuminator including a housing sized to span a keyboard. The housing includes two contiguous, longitudinal sections with the first front section including a light source with a diverter to shed light only on the keyboard. The second back section includes a counterbalancing weight in relationship with the first section.
