研究目的
To develop an optimization model for luminous efficacy of a spectrally tunable LED daylight simulator under constraint of metamerism index for visual appraisal of color.
研究成果
The study found that a spectral tunable LED daylight simulator of AA grade could consist of two QDLEDs with an ultraviolet chip and two other QDLEDs with a blue chip. The optimized system achieved high luminous efficacy and excellent colorimetric performances under the constraints of metamerism indices.
研究不足
The study assumes ideal conditions with radiant efficiency of both ultraviolet and blue chips of 60% and quantum efficiency of quantum dots layer of 90%, which may not be achievable with current technology.
