Patent ID: 7631980

Claim:
A luminaire comprising: a light source for emitting light radiation and a lighting panel comprising a first material and disposed in front of the light source, the lighting panel defining a plane and having a front surface and a back surface substantially parallel thereto; wherein the first material is substantially transparent or translucent; wherein the light radiation emitted by the light source is received at the back surface of the lighting panel and transmitted therethrough towards the front surface; wherein the lighting panel further comprises a plurality of walls embedded therein and extending from the back surface towards the front surface substantially perpendicularly relative to the plane of the lighting panel, the walls comprising a second material that is less translucent than the first material; and wherein the front surface of the lighting panel is profiled in order to reduce the light radiation emitted from the lighting panel at a relatively small angle relative to the plane of the lighting panel, the front surface comprising a plurality of protrusions having a substantially conical surface that tapers from a base portion of the protrusions, the protrusions extending in a direction away from the lighting panel.
