植物照明的关键因素及其测量技术

The Key Factors and Measuring Technology for Plant Lighting

从光质、光密度及光均匀性等方面出发,分析光照对植物照明的关键影响因素,强调照明产品的选择和照明设计需要以特定植物的生长需求为依据,既满足植物健康生长需求,又充分节能环保。可以用一些量化指标来表征这些关键因素,并能进行精确快速地测量,介绍最新的植物照明测量技术,包括实验室测量和现场测量。光谱测量在植物照明的评价方面具有重要作用,不仅准确度较高,而且可方便实现各个计量系统间的量值转换,并可根据个体植物对光质的需求进行深入地分析。

Key factors of light on plant growth are analyzed from the points of light quality, light density and lightuniformity, etc. The results show that the selection and design of lighting products should be based on the growthneeds of a particular plant and realize the goals of plant healthy growth, energy conservation and environmentalprotection. These key factors can be characterized by a number of quantitative indicators, and can be quicklyand accurately measured. A novel measurement technology for plant lighting is described in this paper, includinglaboratory measurements and field measurements. It is worth mentioning that spectrometry plays a very importantrole in the evaluation of plant lighting with the advantage of high accuracy. Moreover, the value conversion betweenvarious metering systems can be easily achieved through spectrometry and an in-depth analysis can be carried outbased on the needs of an individual plant.
