Abstract: A light harvesting lens module for collecting an ambient light includes a plurality of annular lenses. The annular lenses are arranged in order from center to outside to form a disc-structure. Each annular lens has a light-input curved surface and a light-output curved surface. The light-input curved surface is in opposition to the center. The light-output curved surface is in opposition to the light-input curved surface, and faces the center. The light is incident on the light-input curved surface, and is refracted and tend to concentrate by the light-input curved surface. Then, the light is emitted from the annular lens, and is refracted to the direction of the center by the light-output curved surface. The ambient light is able to be compressed into a point light by the lens module, so as to increase the concentration ratio and the compression ratio to further get the effective advantage.

Abstract: A traffic signal system with dual light sources includes a signal displaying module, an ambient light module and a supplementary light module. The ambient light from environment is assembled by the ambient light module for generating a first light beam. A second light beam is provided by the supplementary light module disposed near the ground for easy maintaining and avoiding danger. The supplementary light module includes a sensor and a control circuit. The sensor senses the brightness of the first light beam passing through the signal displaying module and generates a photosensitive signal. The brightness of the second light beam is regulated by the control circuit according to the photosensitive signal. The brightness of the first light beam is supplied by regulating the brightness of the second light beam, so the signal displaying module has high-brightness light source and achieves the energy conservation.

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.
