随着人们对与视觉以外的光响应相关的设计应用越来越感兴趣，开发了两种模拟工具ALFA和Lark，将光的光谱特性纳入室内照明条件的评估中。在研究ipRGC影响的反应时，光的光谱特征特别相关。本文旨在评估这些工具在预测室内光谱辐照度方面的可靠性，特别是从电照明方面。在三种室内电灯照明情况下测量光谱辐照度，并与阿尔法和云雀模拟的光谱辐照度进行比较。虽然研究结果倾向于表明阿尔法更准确、更快，但光谱辐照度的误差较大（-28.6%至33.4%）。与之前针对日光的研究相比，这些结果似乎表明，电灯照明场景的光谱模拟通常不如使用这些工具的日光照明场景的光谱模拟准确。

As the interest in design applications related to responses to light beyond vision is growing, two simulation tools, ALFA and Lark, have been developed to incorporate spectral characteristics of light in the evaluation of indoor lighting conditions. The spectral characteristics of light are of particular relevance when studying ipRGC-influenced responses. This paper aims to assess the reliability of these tools in predicting indoor spectral irradiance specifically from electric lighting. Spectral irradiance was measured under three indoor electric lighting scenarios and compared against spectral irradiance simulated in ALFA and Lark. While the outcomes of the study tend to show that ALFA is both more accurate and faster, rather large errors were found for spectral irradiance (-28.6% to 33.4%). In comparison to a prior study focusing on daylighting, these results seem to indicate that spectral simulations of electrically lit scenes are generally less accurate than those of daylit scenes with these tools.
