Abstract
A lamp system for erasing an electrically charged photoconductive surface including an optically transmissive protective cover fabricated from a polypropylene adhesive tape for being affixed to a segmented surface so as to eliminate exposed gaps in which contaminants may collect and for providing a smooth surface which can be cleaned more efficiently and effectively.
Claims18
A lamp system for erasing an electrically charged photoconductive surface, comprising:
- a light source including a plurality of individually controllable light segments for erasing selected portions of the charged photoconductive surface;
- a lens member for allowing light rays to be uniformly propagated from said light source to the photoconductive surface, wherein said lens member includes a plurality of individual lens segments corresponding to selected segments of said plurality of individually controllable light segments;
- and
- an optically transmissive protective cover for preventing contamination of said lamp system to maintain uniform light output therefrom.
An electrophotographic printing machine of the type in which a light source is employed to discharge selected portions of a charged photoconductive member adapted to have successive electrostatic latent images of original documents recorded thereon, wherein the light source comprises:
- a light emitting diode (LED) array for generating light rays, wherein said LED array includes a plurality of individually controllable LED segments for erasing selected portions of the charged photoconductive member;
- a light pipe for allowing the light rays to uniformly propagate from said LED array to the photoconductive member, wherein said light pipe includes a plurality of individual light pipe segments corresponding to selected segments of said plurality of individually controllable LED segments;
- and
- an optically transmissive protective cover for preventing contamination of the light source to maintain uniform light output therefrom.
