Abstract

In some embodiments, a lighting system comprises: a light source; a lens spaced apart from the light source and including a first surface to receive light from the light source, the lens further including a second surface through which at least a portion of the light received by the lens exits; and a cover spaced from the lens and including a first surface to receive at least a portion of the light that exits the lens, the cover further including a second surface through which at least a portion of the light received by the cover exits; the second surface of the lens including a portion convex with respect to the light source; the first surface of the cover including a portion convex with respect to the light source and disposed over the convex portion of the lens. In some embodiments, the second surface of the cover is flat.
