虽然人类和植物使用光的方式和原因不同，但照明专业人员在这些应用中的基本工作保持不变，即在正确的时间向目标提供具有适当光谱功率分布的适当数量的光。植物和人类应用的光量有不同的特点。对于植物，需要考虑一天中以及整个植物生命周期内的辐照量、交付时间和总光剂量。 适当的光谱功率分布对于植物和人类是不同的，并且在植物物种之间（甚至在一个物种内的不同品种之间）可能会有所不同。本文件描述了建筑照明和园艺照明设计之间的差异，以便照明专业人员获得必要的信息，将其建筑照明技术转化为园艺照明实践。

While humans and plants use light in different ways and for different reasons, the fundamental job of the lighting professional for these applications stays the same-deliver the right amount of light with appropriate spectral power distribution to the target at the right time. The amount of light is characterized differently for plant versus human applications. For plants, the amount of irradiation, the timing of delivery, and the total light dose over the course of a day and throughout the plant life cycle need to be considered.The appropriate spectral power distribution is different for plants and humans-and can vary between plant species (and even between different cultivars within a species). This document describes these differences between architectural and horticultural lighting design, so that lighting professionals will have the necessary information to translate their architectural lighting know-how into horticultural lighting practice.
