The device has light emitting diodes (2a-2e, 3a-3d, 4a-4c) (LEDs) of three different groups arranged in planar units. The LEDs are distributed in a two-dimensional geometrical pattern on the planar units. Planar centroid of the pattern lies on an axle center of the planar units. Centroid of the group pattern lies on an axle center of the planar units. The LEDs are dimensioned based on a desired lighting situation. |
