Abstract
The disclosed embodiments relate to functional and decorative lighting. A transparent body (100) comprises a plurality of light guides (130, 140) forming a matrix. Light is emitted from light sources (210, 220). In the cells of the matrix in which light from different light sources (210, 220) intersects, the light is mixed which results in different cells having different colors.
Claims12
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.
The lighting device according to claim, wherein the first direction is orthogonal to the second direction.
