Element for injecting light having an energy distribution

Abstract

The invention relates to a light injector element (20) comprising a hollow body (21) extending according to a longitudinal axis (22), and a light source (23) placed facing an end (25) of the body (21), the light source (23) being configured to emit a light beam substantially parallel to the longitudinal axis (22) of said body (21), the injector element (20) further comprising at least one optical element (35i) arranged inside the body (21) and configured to let through a fraction of the light beam propagating in a central part (36i) of the body (21), and deflect towards the outside of said body (21) a fraction of the light beam propagating in a peripheral part (37i) of the body so as to locally distribute energy emitted by the light source (23). The invention also relates to a photobioreactor (10) and a domestic lighting element comprising such a light injector element (20).
