Abstract
A cover element for use in a lighting assembly that includes an edge-lit light guide. The cover element includes a first major surface through which light output by the light guide enters the cover element, the light including light propagating at high angles relative to normal to the first major surface of the cover element. The cover element also includes a second major surface opposed to the first major surface and having optical elements that each have plural surfaces arranged relative one another so that the optical element redirects high angle light incident on any one of the surfaces of the optical element and travelling in a direction with any vector component orthogonal to the normal to have a reduced angle in the normal direction as the light exits the cover element through the optical element.
