Abstract: The present invention relates to a microcontroller-based adaptive human-centric lighting system configured for circadian-phase- dependent spectral tuning and programmable illumination control. The system comprises a programmable embedded control unit, independently controllable multi-channel light-emitting diode (LED) sources including red, green, blue, white, and yellow LED channels, switching circuitry, pulse width modulation (PWM)-based intensity control architecture, power regulation circuitry, thermal dissipation assembly, and optical diffusion components configured to generate dynamically variable illumination profiles corresponding to predefined operational phases. The programmable embedded control architecture is configured to independently regulate the intensity of the LED channels to generate adaptive spectral power distributions, correlated color temperature (CCT) variation, chromaticity adjustment, blue light intensity modulation, and phase-dependent illumination characteristics corresponding to morning, midday, afternoon, evening, and night operational conditions. The system is further configured to selectively regulate short- wavelength spectral contribution during predefined operational phases through programmable PWM-based spectral tuning methodologies. The invention additionally provides configurable timing control, smooth spectral transition mechanisms, programmable circadian operational phase mapping, and adaptive illumination management using a compact embedded hardware architecture. The proposed adaptive lighting system is applicable to residential, healthcare, workplace, educational, hospitality, commercial, industrial, wellness, and indoor environmental lighting applications requiring programmable spectral adjustment and dynamic illumination control.
