Abstract:
1. A lighting device comprising: a transparent body having a plurality of light guides extending in a first direction, wherein each light guide is delimited by slits extending in the first direction, and a plurality of light guides extending in a second direction, wherein each light guide is delimited by slits extending in the second direction, wherein the plurality of light guides extending in the first direction and the plurality of light guides extending in the second direction are arranged to intersect thereby forming intersections, a first set of light sources arranged at a first side of the transparent body, wherein the first set of light sources are arranged to emit light through the light guides extending in the first direction, and a second set of light sources arranged at a second side of the transparent body, wherein the second set of light sources are arranged to emit light through the light guides extending in the second direction, wherein light from the first set of light sources and light from the second set of light sources intersect in the intersections formed by the plurality of light guides extending in the first direction and the plurality of light guides extending in the second direction, wherein the first direction is parallel to a perimeter of the transparent body and the second direction is parallel to a radius of the transparent body, or wherein the first direction is orthogonal to the second direction and the third direction is orthogonal to the first direction and to the second direction.
