The illumination band uses a matrix of LED elements (8) attached to a flexible insulating substrate (1a) with printed conductor paths for interconnection of the LEDs. The front face of the substrate (1a) is covered by a metallic conductor (7) incorporating conical cavities (3) separated from one another by a square dielectric grid, with a respective LED(8) at the base of each cavity (3). Pref. the dielectric grid is provided by grooves out in the metallic conductor (7). Each LED (8) has having its anode and cathode attached to the parts of each cavity (3). The front face of the LED matrix is pref. covered by a transparent protective layer.@(12pp dwg.No.3/12)@
