Abstract: The invention provides a lighting device (12) configured to provide both functional lighting for illuminating a space, and simultaneously to present a spatially dynamic sparkling light display. The device comprises a chamber (14) containing one or more light sources (28). The light sources are arranged to direct light in the direction of a translucent surface portion (20), and in the direction of a plurality of light exit areas (32) delimited by the translucent surface portion. The light exit areas each have a higher transmittance than the surrounding surface portion.

Abstract: The invention provides a lighting panel, for use for example within a modular surface system, comprising one or more strips of solid state lighting elements associated with a reflector structure. The lighting panel is adapted for improved uniformity of light intensity across the width of its output area. Lighting elements comprise two or more subsets, each subset adapted to collectively generate a different light intensity profile across the width of the panel output window. The subsets are selectively adapted to generate profiles which, when blended, mutually offset one another's deviations from some common mean intensity across the width of the output window, thereby generating a combined intensity profile of improved uniformity. Embodiments include arrangements in which subsets of lighting elements are adapted to have differing actual or virtual optical path lengths to the reflector surface.
