  • Traffic signal system with dual light sources
    Patent number: 8872672
    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.
