Design and Development of High-Efficiency LED Lighting Systems for Urban Lighting
Keywords:
Smart, Urban, Light, LEDAbstract
Urban lighting remains a major source of energy consumption and carbon emissions in cities worldwide. We report the design and deployment of a high- efficiency lighting system based on light-emitting diodes combined with adaptive dimming and sensor-based control. The system integrates real-time environmental sensing and wireless communication to dynamically adjust light output according to traffic, weather, and ambient conditions. In a pilot urban installation, the LED network reduced energy use by 65–70% compared to conventional high-pressure sodium lamps, while improving illumination uniformity and colour rendering. Photometric measurements and user feedback confirmed enhanced visibility and perceived safety, with minimal light pollution. Simulations for city- wide implementation project substantial reductions in electricity costs and carbon emissions. These results demonstrate the viability of scalable, intelligent street lighting infrastructure that aligns with climate mitigation goals and smart city development, offering a pathway to more sustainable and livable urban environments.
