Claim Text:
1. A lighting assembly, comprising: an LED light source assembly; and a unitary light-transmissive solid reflector optical element comprising a light output surface, the reflector optical element having n light-transmissive solid optical sub-elements, n being an integer three or greater, the sub-elements being n-fold rotationally symmetrical about a central axis, boundaries between adjacent optical sub-elements extending radially outward from the central axis, each optical sub-element comprising a reflective surface positioned opposite the light output surface on the optical sub-element and shaped to create an internal reflection effect; wherein the LED light source assembly comprises an LED light source for each optical sub-element, the LED light sources positioned along an outline near the light output surface radially outwards from the light output surface to direct light from each LED light source towards the reflective surface of the respective optical sub-element such that the light is reflected by the reflective surface to form an output light that exits the reflector optical element through the light output surface.
