Abstract
Disclosed is a product comprising a luminous surface, the product comprising a light guide (10) providing said luminous surface, said light guide comprising a plurality of scattering elements (12) for producing a substantially homogeneous light output across said luminous surface; and a first solid state lighting element (20) arranged to emit a beam of light (30) into the light guide; wherein the light guide further comprises a body (40) arranged to create a region (50) in the light guide shaded from said beam.
Claims11
A lighting panel having a luminous surface, the lighting panel comprising:
- a light guide providing the luminous surface, the light guide comprising a plurality of scattering elements for producing a substantially homogeneous light output across the luminous surface;
- and
- a plurality of solid state lighting elements, each of the solid state lighting elements being arranged along one or more edges of the light guide to emit a beam of light into the light guide, each of the solid state lighting elements having a light output that is partially collimated, wherein the plurality of solid state lighting elements comprises a first solid state lighting element, and a position of the first solid state lighting element is adjustable relative to the light guide;
- wherein the light guide further comprises a first body within the light guide, the first body arranged to create respective regions in the luminous surface that are shaded from the respective beams of light, at least one shaded region arranged within the beam of light, the respective shaded regions with the light output from the plurality of solid state light elements arranged to create light effects.
