Luminex is a complex system involving a combination of optical fibre fabric and electronics. Light emitting diodes illuminate the optical fibres, which distribute the light over the surface of the fabric. The energy required by the LEDs is obtained from a rechargeable battery. Luminex is the product of a cooperative development undertaken by three companies, STABIO Textil SA, CAEN S.p.A and FIT S.p.A. For some time now Luminex S.p.A. has been marketing its light-emitting textile as an industrial product. So far Luminex has mainly been applied in theatres, interiors, accessories, upholstery and in the motor industry.
