A method of light reorientation and recovery, is based on circular mirror system (figure 2) that has the same radius of curvature and the same center as that of the light source with which the system functions. These characteristics allow the system to reorient light rays striking the surface normally in the opposite direction toward the centre of the light source. This reoriented light flux passes through the centre of the light tube, exits, and combines with the non reoriented light flux to give more visible light to the areas desired. In a fluorescent tube, the system is mounted outside the light tube surface, and directly reorients the visible light, or mounted inside the light tube surface, and reorients the ultraviolet light toward the other side of the tube where it then undergoes fluorescence. In either case, the end result is more visible light to the areas where it is desired. |
