(FR) LUMINAIRE A FIBRE OPTIQUE
Abstract
(EN)
A fiber optic luminaire is arranged to couple light energy from a light source (20) along its length. The fiber optic luminaire (10) includes a plurality of light redirecting structures (14) distributed along its length; the light redirecting structures are arranged to uniformly distribute by reflection light energy from the fiber optic luminaire. The light redirecting structures (14) are preferably non-scattering structures, including structures such as microprisms, microfacets, microgrooves and micrometers. The fiber optic luminaire may be configured to a variety of shapes and to provide customized light distribution patterns.

(FR)
La présente invention concerne un luminaire à fibre optique agencé de manière à coupler l'énergie lumineuse produite par une source lumineuse (20) disposée dans le sens de sa longueur. Le luminaire à fibre optique (14) comprend une pluralité de structures de réorientation de la lumière (14) réparties sur sa longueur. Ces structures sont agencées de manière à diffuser uniformément l'énergie lumineuse produite par le luminaire. De préférence du type non dispersant, les structures (14) peuvent être constituées par des microprismes, des microfacettes, des microsillons, etc. Ce luminaire à fibre optique peut se présenter sous diverses formes et fournir un éclairage sur mesure.
