Abstract:
1. A panel assembly comprising: a panel having a light-pervious area; a light-reflecting member coupled to the light-pervious area of the panel configured for reflecting light from a light source to the light-pervious area, the light-reflecting member forming a light-guiding wall with a plurality of spaced slots therein; and a light-shielding board slidably positioned between the light-guiding wall and the light-pervious area, the light-shielding board defining a plurality of spaced slots corresponding to the slots of the light-guiding wall for allowing the light passing through the light-pervious area when the slots of the light-shielding board align with the slots of the light-guiding wall respectively, light-shielding bars being formed between adjacent slots respectively; wherein the light-shielding board is slidable along the light-reflecting member to cause the slots of the light-shielding board to be removed from the corresponding slots of the light-reflecting member and the light-shielding bars of the light-shielding board to cover the corresponding slots of the light-reflecting member, to thereby shield the light reflected from the light-reflecting member from passing through the light-pervious area.
