其他文件描述了灯具光度和组件数据分布的标准文件格式。还需要分发光谱数据。这些数据与光源的光谱辐射通量、滤色片的光谱透射率以及油漆和其他饰面的光谱反射率有关，但不限于此。这些数据可在测试光源、灯具或材料时获得，然后可用于照明应用软件、渲染软件、分析软件或光学设计软件。本文件规定了光谱数据传输的电子（基于XML）数据格式。本文件可用于传输光辐射光谱数据，包括光源、灯具和灯具，以及材料的反射光谱和透射光谱。 该文件仅限于包含单个光谱数据集。

Other documents describe standard file formats for the distribution of luminaire photometric and component data. There is also a need to distribute spectral data. Such data are pertinent, but not limited, to the spectral radiant flux of light sources, the spectral transmittance of color filters, and the spectral reflectance of paint and other finishes. These data may be obtained when testing a light source, luminaire, or material and may then be used in lighting application software, rendering software, analysis software, or optical design software. This document specifies an electronic (XML based) data format for the transfer of spectral data. This document may be used for the transfer of spectral data of optical radiation including light sources, lamps, and luminaires, as well as reflectance and transmittance spectra of materials. The document is limited to containing a single spectral data set.
