A light reflecting assembly includes a cabinet and a light reflecting member. The light reflecting member includes a center reflecting part, four peripheral reflecting parts and a tongue part. Side end portions of an adjacent pair of the peripheral reflecting parts form a corner section of the light reflecting member at a corner portion of the center reflecting part while the light reflecting member is attached to the cabinet. The tongue part extends from one of the side end portions of the adjacent pair of the peripheral reflecting parts towards the other of the side end portions of the adjacent pair of the peripheral reflecting parts. The tongue part at least partially overlaps with the other of the side end portions of the adjacent pair of the peripheral reflecting parts while the light reflecting member is attached to the cabinet.
