title: Optimal spectra of white LED integrated with quantum dots for mesopic vision.
abstract: The spectral optimization model for limited mesopic luminous efficacy (LLEm) of white LED integrated with quantum dots (QD-WLED) consisting of a blue chip, green, yellow and red quantum dots, including down-conversion energy loss, was developed under constraint of designated color rendering properties. The optimal spectra of QD-WLEDs with CRI ≥ 70 and CQS ≥ 60 as well as CRI ≥ 85 and CQS ≥ 85 for mesopic vision, photometric and colorimetric performances at correlated color temperature of 2700 K to 45000 K, as well as the LLEms of optimal QD-WLEDs for four road lighting standards of the USA and the UK were presented. These results suggest that QD-WLEDs make strong candidates for replacing conventional light sources in the future as they enhance the vision quality in the road lighting in addition to energy saving.
