研究目的
Investigating the effects of different mathematical models on the accuracy of LED spectral power distribution (SPD) modeling and its impact on color quality parameters and luminous efficiency.
研究成果
Physical models of light emission from solid-state lighting are not ideal for precise LED SPD modeling. No single unique model maintains the lowest approximation errors across different LED emitters. Asymmetrical double sigmoidal models show more precision than Gaussian functions. Future research will expand to ultraviolet and infrared spectrum ranges and focus on phosphor-covered white LEDs.
研究不足
The study is limited to three specific LED emitters and does not cover ultraviolet and infrared spectrum ranges or phosphor-covered white LEDs. The determination of parameters is sensitive to initial conditions.
