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.

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.

A light-concentrating panel is disclosed. The light-concentrating panel comprises a planar light collecting element and a linear light collecting element. The planar light collecting element receives and collects the planar light, and then emits out as linear light. The linear light collecting element receives the linear light. The linear light from the planar collecting element enters the linear light collecting element by passing a planar-linear imaginary plane, which is located between the planar light collecting element and the linear light collecting element. The linear light from the planar collecting element are collected and turned into the spot light by the linear light collecting element.
