Abstract

See full text

A single piece light pipe is designed to provide dual-field, multi-color, multi-directional illumination. The light pipe is combined with a single PCB having a plurality of LEDs to create a compact illuminator that can selectively provide dark field and bright field with red, green, blue color, broad spectrum, or combination of any color in horizontal, vertical, diagonal, or combination of any direction. The single piece light pipe is compact in size and light in weight. The non-closed form option not only can further reduce the weight but also can allow arrange opening area clearance for: (1) visual aiming and alignment in application, especially for hand held application; (2) reducing illumination crosstalk to unwanted directions; and for (3) mechanical integration. The improvements allow the illuminator to read direct product marking (DPM) type of barcodes.
