Abstract

A lighting panel (10) comprises light source means (22, 24) and a reflector (18), the light source means being located at or near to the periphery of the panel and the reflector being operable to reflect light from the light source means so as to give the appearance of substantially uniform illumination across the panel. The reflector (18) may advantageously be operable to scatter the light from the light source means which is preferably a plurality of light-emitting diodes. The lighting panel may advantageously further comprise a translucent element (20) operable to diffuse light reflected from the light source means and further diffusion means (26, 28) interposed between the light source means and the translucent element (20) and operable to diffuse light emitted from the light source means in the direction of the translucent element.
