LUMINAIRE WITH A LIGHT DIFFUSER AND ASSOCIATED METHOD
A luminaire comprising: a light source (10); an exit window (20) for light from the light source; and a diffuser (25; 200a; 200b; 200c; 200d) at the exit window for diffusing the light. The diffuser comprises a plurality of micro-optical elements (203a; 203b; 204, 205; 206, 207). Each micro-optical...

| description | A luminaire comprising: a light source (10); an exit window (20) for light from the light source; and a diffuser (25; 200a; 200b; 200c; 200d) at the exit window for diffusing the light. The diffuser comprises a plurality of micro-optical elements (203a; 203b; 204, 205; 206, 207). Each micro-optical element is adapted to redirect light from the light source, so that the redirected light from each element emerges from the diffuser at a respective predetermined polar angle (Θ). The plurality of micro-optical elements comprise first micro-optical elements, which redirect light from the light source into a first range of polar angles, wherein the first optical elements occupy a greater proportion of the area of the diffuser in a first neighborhood than in a second neighborhood, and wherein the first neighborhood receives less light from the light source than the second neighborhood. Also provided is a method of designing and manufacturing a diffuser for such a luminaire. |
