Inventor(s) include Kiran C; Jeevitha M.; Meenakshi S J; Niketh R Hebbar; Mallikarjun S Kalashetty; and Lokesh N Gouda.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "Street lighting plays an important role in ensuring safe visibility on highways and urban roads during nighttime. Conventional street lighting systems remain continuously illuminated throughout the night regardless of traffic conditions, which leads to significant energy wastage and increased operational costs. To address this issue, an intelligent lighting system that operates based on real-time traffic movement is required. The present invention proposes a smart street lighting system that uses infrared (IR) motion sensors to detect the presence of vehicles or pedestrians on the roadway. The sensors are installed near street light poles and continuously monitor movement within their detection range. When motion is detected, the corresponding LED streetlight is automatically activated to illuminate that section of the road. In the absence of movement, the light remains turned off, thereby conserving electrical energy. The system consists of multiple street lighting units, each equipped with an IR sensor, LED lamp, power supply, and control circuitry. As vehicles move along the roadway, the sensors sequentially activate nearby streetlights while other lights remain inactive. This targeted illumination approach reduces unnecessary power consumption compared to conventional street lighting systems that remain active throughout the night. The proposed system improves energy efficiency, extends the lifespan of lighting equipment, and reduces maintenance costs. It is particularly suitable for highways, rural roads, and low-traffic areas. The system can reduce electricity consumption by approximately 40-50% compared to traditional street lighting methods, making it a practical and sustainable solution for modern roadway lighting."
