A lighting panel 10 is provided, the panel comprising a plurality of light sources 60, 62, 64, such as LED's, located at the panel's periphery and arranged to direct light 66, 68, 70 onto at least one reflecting surface 21 etc, of the panel to give the appearance of substantially uniform illumination there across. The light sources are arranged in clusters 50 to 59, each of two or more light sources 60, 62, 64, of differing colours, preferably red, blue and green, the spacing in between neighbouring clusters being greater than that between neighbouring sources in any of the clusters. Further disclosed is the orientation of one or all of the clusters so as to improve the effective mixing of the light and uniformity of the illumination. |
