Abstract:
A laminated optical disk, applied for lighting system or solar energy system, includes a plurality of annular lenses, a base and a circular light guiding unit. The annular lenses are arranged in order from center to outside to form a disk-structure. Each annular lens has a light-input curved surface and a light-output curved surface respectively matching the different thickness of the base. The light-input curved surface is opposite to the center. The light-output curved surface is opposite to the light-input curved surface, and facing to the center. The light is incident on the light-input curved surface, refracted and tended to concentrate by the light-input curved surface. Besides, the light exiting from the annular lens is to be refracted to the direction of the center by the light-output curved surface. The base of the laminated optical disk can significantly improve the light leakage problem by different annular lenses.
