LIGHTING ARRANGEMENT

摘要

Lighting arrangement (1, 1′) comprising a light source (2) for generating light; a spreading element (3) realised to laterally spread the generated light in a spreading plane (S), defined by an optical axis (AO) of the light source (2) and a longitudinal axis (L) of the spreading element (3), to give an essentially uniform quantity of light per unit area at an emission face (41, 51) orthogonal to the spreading plane (S) and parallel to the longitudinal axis (L) of the spreading element (3) and a light redirecting element (4, 5) arranged to collect the spread light, which comprises a longitudinal planar emission face (41, 51), and is realised to collect the laterally spread light and to emit the collected light essentially uniformly from the emission face (41, 51).

1. A lighting arrangement comprising a light source for generating light;
a spreading element configured to laterally spread the generated light in a spreading plane, defined by an optical axis of the light source and a longitudinal axis of the spreading element, to give an essentially uniform quantity of light per unit area at a plane orthogonal to the spreading plane and parallel to the longitudinal axis of the spreading element; and a light redirecting element provided with a collecting face to collect the laterally spread light and an emission face to emit the collected light, wherein the light redirecting element is configured to emit the collected light essentially uniformly from the emission face, the emission face is longitudinal planar, and the collecting face comprises a plurality of distinct lateral refracting zones for collecting the laterally spread light, wherein a distinct lateral refracting zone comprises a collecting face arranged to collect a light portion having a certain incidence angle range, and a refracting body for refracting the light portion through the emission face.
