Abstract
An LED video display includes an array of LED elements mounted on an LED panel. A light baffle has openings to accept the LED elements, and reflectors are formed about each LED opening. A shader or rib is provided above each LED reflector in the light baffle. A second rib is provided below each LED reflector to form a rib pair between adjacent LED reflectors. Mounting openings in the light baffle are in place of the rib pair that would otherwise be present in the arrangement of ribs. A mounting clip having a rib pair is fastened to the LED panel. The rib pairs of the mounting clips are inserted through the mounting openings in the light baffle to secure the light baffle and LED panel to one another. The rib pairs of the clips align with the rib pairs of the light baffle.
