Inventor(s) include Karuppanasamy; Hemachandriga; Chinnumole G; Shapna S; Subhasri K; Dr. Sundar Raj M; Kaaviyakanth K; Dhivya Parameswari; and Kailasapathi T.

The application for the patent was published on Oct. 10, under issue no. 41/2025.

According to the abstract released by the Intellectual Property India: "The gravity-based smart lamp represents a paradigm shift in lighting technology, harnessing the natural force of gravity to power illumination. At its core, a carefully calibrated sandbag mechanism stands ready, filled with rocks and sand, poised to release its stored gravitational potential energy. As the sandbag descends, its movement activates a generator, seamlessly converting kinetic energy into electrical power. This power is then intelligently managed by a control system, ensuring optimal lighting conditions based on user preferences and environmental factors. From residential living spaces to sprawling industrial complexes, the gravity-based smart lamp offers customizable and energy-efficient lighting solutions tailored to diverse applications. In an era marked by a growing emphasis on sustainability and energy conservation, the gravity-based smart lamp emerges as a beacon of innovation. Unlike traditional lighting systems reliant on external power sources, this lamp operates independently, drawing upon the inexhaustible force of gravity. Through meticulous design and rigorous testing, it has been proven to deliver reliable performance, with significant energy savings compared to conventional alternatives. Its versatility and adaptability make it suitable for a wide range of environments, promising to revolutionize the way we illuminate our surroundings while contributing to a greener, more sustainable future."
