高性能LED植物生长照明光源研究

High Performance LED Lighting Source for Plant Growing

传统的植物照明光源存在着发光效率低、功耗高、光谱分布不全以及与被照植物所需要的光谱不相匹配等问题,效果并不理想。LED包含有红、绿、蓝等色彩丰富的单色光,具有极窄的光谱特性、较高的效率、超长的寿命,且与植物生长所需要的光谱匹配性良好,因此非常适用于在植物照明上的应用。在一般性介绍植物生长与光照关系的基础上,重点就高性能LED植物生长照明光源进行探讨,主要包含光照的均匀性、光配比的合理性等相关问题。

Traditional lighting sources for plant growing have some problems, such as low luminous efficiency, high power consumption, and the spectral distribution is not complete and does not match the spectrum the plants need, so the effect is not ideal. LED contains rich monochromatic light such as red, green, and blue, its extremely narrow spectral characteristics, high efficiency, long life, and good spectral matching for the plant growing, enables it very suitable for application in plant lighting. Based on general introduction of the relationship between plant growth and sunlight, the paper mainly discusses the high performance LED lighting source for plant growing, includes illumination uniformity, the rationality of the ratio of light and other related problems.
