(SPIE–International Society for Optics and Photonics) An article published in the SPIE journal Optical Engineering, ‘Arbitrary spectral matching using multi-LED lighting systems,’ marks a substantial advance in lighting science and technology. In their paper, the researchers announce a two-pronged approach to both measure and self-adjust the spectral power distributions (SPDs) of LED lighting systems. Their methodology demonstrates the system’s ability to maintain consistency and stability over an extended period of time.
