US Patent 7530713 Light-reflecting and light-shielding apparatus of computer panel

A panel assembly for reflecting and shielding rays of a light source, includes a panel, a light-reflecting member attached to the panel, and a light-shielding board received in the light-reflecting member. The panel includes a base and a bent plate perpendicular to the base. A light-pervious board is disposed on the panel. The light-reflecting member defines an opening opposite to the light pervious mechanism, for reflecting some rays on the light-pervious mechanism through the opening. Wherein the light-shielding board is manipulated to move along a direction vertical to the light-reflecting member. When the light-shielding board is positioned in an upper position, the opening of the light-reflecting member is exposed to allow rays through the light-pervious board. When the light-shielding board is positioned in a lower position, the opening of the light-reflecting member is covered, and no rays are reflected to the light-pervious board.
