This article deals with tracking a reference spectrum, enhancing the circadian entrainment of the occupants. The choice of the reference spectrum was made with an emphasis on maintaining the CCT, maintaining a CRI value of at least 80 for the general work area, and maintaining the luminous flux. Use of the Levenberg–Marquardt (LM) algorithmLevenberg-Marquardt (LM) algorithm results in the optimal number of LEDs needed for spectrum synthesis. As a result, this work intends to offer a solution for making a luminaire. The percentage error in CCT for the simulated spectrums was less than 0.4%. The daylight spectrumDaylight Spectrum is also selected as a reference spectrum so that close characteristics of sunlight are reached, meeting human comfort needs while also delivering the advantages of sunlight. This novel method of keeping a reference spectrum to design a LED luminaire for circadian entrainment with high luminous efficacy leads to the human-centric lighting system.
