MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541085878 A) filed by Manipal Academy Of Higher Education, Manipal, Karnataka, on Sept. 10, 2025, for 'a system and method for constant light output maintenance by led luminaire driver.'
Inventor(s) include Anjanpadmasali; Savitha G. Kini; and Kishore K.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a constant light output LED luminaire system and method for maintaining uniform illumination throughout the operational lifetime of the luminaire. Conventional LED drivers supply constant voltage or current, resulting in gradual lumen depreciation over time and reduced workspace illuminance, with end-of-life defined by the L70 criterion. The invention overcomes this limitation by incorporating a light sensor within the luminaire housing to provide real-time feedback of the emitted light, unaffected by ambient sources. A driver circuit with a boost converter and a microcontroller dynamically adjusts the operating conditions based on the feedback, thereby compensating for lumen degradation and maintaining constant light output. The system ensures that useful life concludes only when the LED luminaire completely ceases to emit light, thus improving user comfort, extending effective service life, and reducing premature replacement costs in residential, commercial, and industrial lighting applications."
