Abstract
A lighting element in which a plurality of point sources are in the form of LEDs situated between a microprism sheet and a reflective backing arrangement, the microprism sheet being of the type having a plurality of v-shaped grooves. The microprism sheet exhibits a diffusion effect, and the LEDs are situated in the grooves so that light from the LEDs that is directly incident on walls of the grooves, and light that is reflected by the backing, is 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.
