MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541060678 A) filed by Sona College Of Technology, Salem, Tamil Nadu, on June 25, for 'wavelength optimization for enhanced plant growth and energy efficiency.'
Inventor(s) include Mr. R. Vinoth; Mr. R. Dharaneshwar; Mr. K. P. Ranjithkumaran; Mr. G. Sanjay; and Mr. M. Santhosh.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The invention presents an intelligent lighting system designed to optimize the wavelength and intensity of artificial light to enhance plant growth while minimizing energy consumption. Using an array of RGB LEDs controlled by a Raspberry Pi Pico microcontroller and real-time feedback from Light Dependent Resistor (LDR) sensors, the system dynamically adjusts light spectra tailored to specific plant growth stages such as vegetative, budding, and flowering. Incorporating a Deep Deterministic Policy Gradient (DDPG) machine learning algorithm enables adaptive control to maximize photosynthetic efficiency and promote healthy plant development. This automated approach improves yield, reduces power wastage, and supports sustainable agricultural practices in controlled environments like greenhouses and vertical farms."
