N2 - 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) 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 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.
