The spectral distribution is a fundamental property of non-monochromatic optical radiation. It is commonly used in research and practical applications when studying how light interacts with matter and living organisms, including humans. In the field of lighting, mis-conceptions about the spectral distribution of light are responsible for unfounded claims, which pervade the scientific and technical communities. Starting from the definition of the spectral distribution, this paper describes the ambiguities and errors associated with a purely graphical analysis of the spectral distribution. It also emphasizes the importance of considering the particle nature of light in research involving both visual and non-visual effects, which implies using the spectral distribution expressed in the photon system of units, a system that has been seldom used in lighting research for historical reasons. The authors encourage lighting engineers and researchers to determine which system is best suited to their work and then proceed with the correct use of spectral distributions and of spectral weighting functions for applications involving optical radiation.
光谱分布是非单色光辐射的一个基本特性。在研究光如何与物质以及包括人类在内的生物体相互作用时，它常用于研究和实际应用中。在照明领域，关于光的光谱分布的误解导致了毫无根据的说法，这些说法在科技界普遍存在。本文从光谱分布的定义出发，描述了与光谱分布的纯图形分析相关的模糊性和误差。它还强调了在涉及视觉和非视觉效应的研究中考虑光的粒子性质的重要性，这意味着要使用以光子单位系统表示的光谱分布，由于历史原因，该系统在照明研究中很少使用。作者鼓励照明工程师和研究人员确定哪种系统最适合他们的工作，然后在涉及光辐射的应用中正确使用光谱分布和光谱加权函数。
