摘要:
Two embodiments for an illumination system are described as a lighting system for computer keyboards and copy text holders and any related printed materials. The first embodiment, a novel keyboard lighting fixture, which is the principal device and includes a base for securing to the underside of keyboards or directly onto a work station, fixed or movable, thereby stabilizing the light fixture to allow pivoting of the housing. The pivoting of the housing to a desired operational position energizes the system which is powered by a plug-in transformer. The second embodiment, the copy text illuminator, is half the size of the keyboard light and is powered by a cord that connects the two light fixtures, making it an auxiliary fixture, to the keyboard light. The cord allows total flexibility and the employment of Velcro pads on each end together with a Velcro strap, enables placement of this light fixture on horizontal or vertical work surfaces. The auxiliary light fixture is powered via the keyboard light or via a stand-alone transformer. The keyboard light and the auxiliary fixture are mounted so that light emitted is directed only onto the keyboard or the copy text holder.
