每个室内空间都需要一些电气照明。适当的光源选择取决于照明系统的功能和美学要求、经济和能源使用限制，以及设计师和/或空间所有者的个人偏好。每种照明技术都有独特的特点，使其或多或少适合于特定的应用。本文件详细介绍了操作原理、技术特点和系统配置。其目的是帮助参与光环境设计的人员选择光源，包括建筑师、室内设计师、工程师、照明设计师、业主、可持续发展顾问、能源工程师、景观设计师、照明产品代表、照明制造商、承包商和分销商。

Some electric lighting is necessary for every interior space. Proper light source selection depends on the functional and aesthetic requirements placed on the lighting system, economic and energy usage restrictions, and the personal preferences of the designer and/or the owner of the space. Each lighting technology has unique characteristics that make it more or less desirable for specific applications. In this document, details are provided regarding operating principles, characteristics of the technology, and configuration of systems. The intent is to help facilitate light source selection for those involved in the design of the luminous environment, including architects, interior designers, engineers, lighting designers, owners, sustainability consultants, energy engineers, landscape architects, lighting product representatives, lighting manufacturers, contractors, and distributors.
