Paper Abstract
Recent advances in LED technology have relegated the use of optical fibre for general lighting, but there are
several applications where it can be used as scanners lighting systems, daylight, cultural heritage lighting,
sensors, explosion risky spaces, etc. Nowadays the use of high intensity LED to inject light in optical fibre
increases the possibility of conjugate fibre + LED for lighting applications. New optical fibres of plastic
materials, high core diameter up to 12.6 mm transmit light with little attenuation in the visible spectrum but there
is no an efficient and controlled way to extract the light during the fibre path. Side extracting fibres extracts all
the light on 2π angle so is not well suited for controlled lighting. In this paper we present an extraction system for
mono-filament optical fibre which provides efficient and controlled light distribution. These lighting parameters
can be controlled with an algorithm that set the position, depth and shape of the optical extraction system. The extraction system works by total internal reflection in the core of the fibre with high efficiency and low cost. A 10 m length prototype is made with 45° sectional cuts in the fibre core as extraction system. The system is tested with a 1W white LED illuminator in one side.
