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.

Abstract translation: 应用于照明系统或太阳能系统的层压光盘包括多个环形透镜，基座和圆形导光单元。 环形透镜从中心到外侧依次布置以形成盘结构。 每个环形透镜都具有分别与底座不同厚度匹配的光输入曲面和光输出曲面。 光输入曲面与中心相反。 光输出曲面与光输入曲面相对，面向中心。 光入射在光输入曲面上，折射并倾向于通过光输入曲面集中。 此外，从环形透镜出射的光将被光输出曲面折射到中心的方向。 层叠光盘的底座可以显着改善不同环形透镜的漏光问题。
