Solar-Powered LED Streetlights Integrated With VLC In Bridging Illumination And Communication

Solar panels mounted on streetlights couple sunlight during the day, converting it into electricity that is stored in batteries. This stored energy powers Light Emitting Diodes (LEDs) used streetlights at night, offering both efficient and eco-friendly illumination. Beyond lighting, these LED streetlights acts as communication hubs. By modulating their light at high frequencies the LEDs can transmit data through Visible Light Communication (VLC) to nearby devices like vehicles, sensors and smartphones. This approach provides a renewable energy source reducing reliance on the power grid and cutting overall energy consumption. VLC utilizes the existing streetlight infrastructure for data transmission, eliminating the need for additional communication systems and boosting the sustainability of urban networks. VLC-enabled streetlights can support real-time communication for various smart city applications including traffic management and environmental monitoring with low energy consumption and better spectral efficiency.
