Abstract: An optical reading apparatus for scanning and decoding data encoded in any of a plurality of types of 1D and 2D bar code symbology. An array of white light emitting diodes are used as an illumination source for the optical reading apparatus, allowing detection of symbologies from a target of interest regardless of the color of the symbology and/or the background of the target. The white LEDs produce a higher color temperature to allow better discrimination of the colors of the target than other known illumination sources and further produces a substantially continuous spectrum, to replicate that of a conventional white light source.

Abstract: A nose adapter for use with light boxes that illuminate fiberoptic light bundles. A retaining member is provided with a mounting aperture having predetermined standardized interior dimensions. One or more insert members are each provided with standardized exterior dimensions which are approximately equal to those of the mounting aperture, and with interior dimensions which are approximately equal to those of the end of a particular light bundle. First fastening means allows the light bundle to be easily inserted into and removed from its insert. Second fastening means allows the nose adapter as a whole to be easily attached to and detached from the light box.
