LIGHT GUIDES, ILLUMINATED ARTICLES AND DEVICES

摘要

A side-emissive flexible polymeric light guide (1) is formed with a main body portion (6) and an integral attachment or anchoring element (7) that extends along its length for attaching the light guide (1) to an item. The attachment element (7) may be in the form of a flat strip of material which may be stitched to an item or may be formed for a snap-fit or in any other appropriate form, e.g. a rib and groove profile. The attachment element (7) is preferably opaque and co-extruded with the main body portion. The light guide may provide effective and simple to use trim and piping and may be used with bags, mobile phone pouches, clothing, furniture and signage. Various new mobile phone alert and signage systems are also disclosed which may, but need not, include a light guide having an integral attachment element.
