Lighting apparatus comprising light-flux refracting means provided in correspondence of a face (45) of a plate (40) of optically transparent material. In this way, the light flux generated by an electric source arranged along a portion (43) of the periphery of the plate (40), penetrates along the same plate in a direction that is parallel to the two faces (45, 46) thereof, and, upon being deflected by 90 degrees, diffuses from the face (46) opposite to the face on which said refracting means are arranged. |
