Title: LIGHTING DEVICE
Abstract:
The invention provides a lens comprising a plurality of imaging regions, each adapted to image a light source to generate a plurality of virtual light sources common to all imaging regions and distributed along a spatial path extending in a direction generally away from the lens. Each imaging region comprises a plurality of sub-regions for focussing the input light source to a corresponding plurality of focal points common to the imaging regions. The focussed light directed to the focal points sub-regions of each imaging region combines so as to form at each focal point a virtual light source. An optical deglaring plate comprising an array of conical optical structures is used with the lens.
