  • Publication number: 20160308358
    Abstract: The present invention discloses a light system with energy management function and control method thereof. The lighting system based on plastic forming technology. That is an application of energy storage module that balances the off-peak electricity to be used at noon. The principal merit is replacing the independent emergency lighting equipment attached at wall. By comparing these two systems, it is realized that the illumination and cost are much better than the traditional type of emergency lighting equipment due to the weathering quality of using plastic forming technology. Furthermore, this invention is much available be applied in outdoor.
