<p>A lighting element in which a plurality of point sources (2) in the form of light-emitting-diodes are situated between a microprism sheet (1) having a plurality of V-shaped grooves (4) and a reflective backing arrangement (3). The microprism sheet exhibits a diffusion effect, and the light-emitting-diodes are situated in the grooves so that light from the light-emitting diodes that directly incident on walls (5,6) of the grooves and light that is reflected from the relective backing arrangement are combined by refraction and diffused to provide an even lighting effect. The lighting element may be made of flexible materials so that they can be formed into tubular lighting elements, or made into flat or curved panels.</p> |
