APPARATUS, METHODS AND ARTICLES OF MANUFACTURE FOR A CO-EXTRUDED LIGHT PIPE

摘要

A light pipe may be used to illuminate an elongated area. Light may emanate laterally relative to the axis of the light pipe, and the light intensity is substantially uniform along the length of the light pipe. The light pipe may include a translucent member and a opaque reflective member that is separate d from the translucent member by a space. A band of reflective material may be located on an exterior surface of the translucent member. The entire light pipe may be formed by co-extrusion of the translucent member, the band of reflective material and the opaque section through a single co-extrusion die . Light emitted laterally from the translucent member toward the arcuate opaqu e reflective member and band of reflective material may be reflected laterally through the translucent member transverse to the axis of the light pipe, so that all light extends through the front surface of the translucent member.< /SDOAB>
