ABSTRACT:
A panel assembly for reflecting and shielding rays of a light source (20), includes a panel (10) and a light-reflecting member (30) pivotably mounted to the panel. The panel includes a base (11) and a bent plate (13) perpendicular to the base. A light-pervious board (131) is disposed on the panel. The light-reflecting member defines an opening (32) facing the light pervious area, for reflecting light rays to be incident on the light-pervious area through the opening, wherein the light-reflecting member is rotatable to change position of the opening of the light-reflecting member relative to the light-pervious area, thereby adjusting the brightness of the light-previous area.
