植物照明的国内外标准化进展和关键检测技术

Development of Standards and Testing Method for Plant Lighting

植物生长与光照条件关系密切,不同于通用照明,植物照明的关键因素包括光质、光密度、均匀性等。然而,植物照明涉及到多学科领域,并且这些领域又是完全不同的行业,因此在术语定义以及测量评价方法等方面存在一定的混乱,影响了先进照明技术在设施农业中的应用和推广,因此国内外相继出台或者正在研究制定相关标准。本文在充分调研的基础上,详细介绍了关于植物照明术语与测量的国内外标准进展情况。对于植物照明评估而言,由于涉及到的计量体系较多,且各种植物对光质要求不同,因此光谱测量至关重要,文章结合现有植物照明检测技术中存在的光谱失匹配、测量精度低等问题,提出了针对植物照明的光谱测量方法,该方法具有测试参数全面、测量精度高、测量速度快的优点,可广泛应用于各种植物照明现场的测量中。

Light plays an important role in plant growth. Different from general lighting, plant lighting includes such key factors as light quality, light density and uniformity and so on. However, with characters of multidisciplinary fields, the quantities, definitions and assessment methods are all very chaotic, preventing the application of advanced lighting technology in agriculture. Currently, some standards have been released or have been drafting. In this paper, the proceeding of domestic and foreign standards is introduced based on enough research. Besides, for the evaluation of plant lighting, based on the different spectrum absorption of different plants, the measurement of spectrum is emphasized. Finally, combined with shortcomings as spectrum mismatch and low accuracy of current technology, spectrum measurement method for plant lighting is proposed, with advantages as high measurement accuracy, high speed and comprehensive measurement parameter.
