摘要
激光二极管(LD)与发光二极管(LED)同为新型半导体光源,在节能、单色光和冷光源等方面优势明显,但在发光角度、照射面积和照射距离方面存在明显差异。LD的波长控制更加精准,光电转换效率更高,输出能量集中,使用寿命更长,照射距离远。LD照射下可栽培植物,可促进植物的生长发育,提高产量积累和品质。基于LD远程激发植物生理活性的特征优势,作者提出了LED与LD相结合的人工光植物工厂应用模式,在LD灯的设计、光照模式和应用策略方面需要创新。本文总结了人工光植物工厂LD照明应用的植物生理基础、应用模式和策略。
Laser diode(LD)and light-emitting diode(LED)are novel semiconductor light source,having multiple advantages of energy-saving,monochromatic light and cold light source.However,they differ in emitting angle,light area and distance greatly,which determines the application pattern in plant factory.LD has more precise wavelength,higher photoelectric conversion efficiency,longer lifetime,and far irradiation distance.It is approved that LD could be used as sole light source for plant production,and higher yield and quality.Based on the characteristic advantage of remote excitation of plant physiological activity by LD irradiation,the author put forward the feasible use patterns of LD,i.e.integration of LED and LD,which raise new innovation requirements to LD lamp design,and light mode and application strategy.In this paper,the plant physiological effects of LD in plant factory are collected,and application pattern and strategy of LD in plant factory are discussed.
