摘　　要：LED推动设施园艺进入光环境(光质、光强和光周期)精准控制时代,世界范围内设施园艺半导体照明方兴未艾。LED光源与灯具效率增加、农业生物光生物学规律的解析是节能LED照明系统装备研发及构建高光效应用策略的基础。文章概括了设施园艺半导体照明的定义、应用领域及复杂性,论述了LED照明系统装备的构成及其光效提升途径,研究进展与前景。LED lighting system research and development for protected horticulture has undergone almost thirty yearsworldwide based on LED invention which propelled electric lighting into a new stage with intelligent and precisecontrol in light quality, intensity and photoperiod, as well as diverse lamp design. Efficiency of LED device and lamp,understanding of agricultural organisms are the basis of the development of high-efficient LED lighting systems andthe establishment of application strategy. In this paper, definition, application fields, and complexity of semiconductorlighting for protected horticulture are put forward, and components of LED lighting system and pathways of lightingefficiency improvement are expounded. Finally, some progresses and prospects are collected.
