本研究报告最初发表在1987年《CIE期刊》第6卷第1期23-31页。为了计算一个或一组人造和安装的灯具撞击或离开该表面的光，有必要了解每个灯具在所有球面角度下的光强分布，这些灯具将光贡献给该表面。个人微型计算机的出现使得每个技术人员都可以使用合适的应用程序进行自己的计算。通常的做法是将特定灯具（光度数据集）的大量球面角度的光强度记录到磁介质（如计算机磁盘）上。虽然磁盘和计算机之间的尺寸、形状和其他技术特征的标准化已由其他方完成，但从磁盘读取数据的计算机程序有必要了解有关灯具、光源和记录数据的角度的数据传输顺序。 这被称为“文件格式”。虽然许多国家和国家内的公司已经采用了特定的文件格式，但有必要采用国际文件格式，以便特定国家的光度数据集可以（通过计算机程序）转换为国际文件格式；或者，以国际文件格式接收的光度数据集可以（通过计算机程序）转换为特定国家使用的特定文件格式，或由个人或公司开发的特定应用程序。CIE推荐的文件格式不用于手动计算，以确定特定角度下的特定光强度，而是易于无误地读取到计算机程序中，用于转换为另一种格式，或用于计算照明装置的结果。 该出版物共有28页，4位数字。可从维也纳的CIE国家委员会或CIE中央局随时获取。

This Research Note was originally published in CIE-Journal, Vol. 6, No. 1, 23-31, 1987.In order to calculate the light striking a surface or leaving that surface from one or a group of man made and installed luminaires, it is necessary to know the light intensity distribution at all spherical angles from each luminaire that contributes light to that surface. The advent of personal micro-computers has made it possible for each technical person to perform his own calculations using a suitable application program. It is common practice to record the light intensity at a large number of spherical angles from a specific luminaire (photometric data set) onto magnetic media, such as a computer disk. While the standardization of the size, shape and other technical features between disks and computers has been done by others, it is necessary for the computer program reading data from the disk to know the sequence of data being transmitted about the luminaire, light source, and angles at which the data has been recorded. This is termed the "file format".While many countries, and companies within countries, have already adopted a specific file format it is necessary to have an international file format so that the photometric data set specific to a particular country can be translated (by computer program) into the international file format; or that a photometric data set received in the international file format, can be translated (by computer program) into the specific file format used in a particular country or a specific application program developed by an individual or company.The CIE Recommended File Format is not intended to be used for manual calculations to determine the specific light intensity at a specific angle, but rather to be easily read, without error, into a computer program, either for translation into another format, or for calculation of the results of a lighting installation.The publication contains 28 pages, with 4 figures. It is readily availabe from the National Committees of the CIE or the CIE Central Bureau in Vienna.
