Abstract

The invention provides a solar three-dimensional lighting system for a closed plant factory. The solar three-dimensional lighting system comprises a plurality of light condensing units, a plurality of infrared separation and absorption units and a plurality of sets of light conduction units, wherein the light condensing units are arranged at the top of the plant factory in an array; each infrared separation and absorption unit is located at the light emitting side of each light condensing unit; and each set of light conduction units is located on the light emitting side of each infrared separation and absorption unit and located in the plant factory. According to the solar three-dimensional lighting system for the closed plant factory, sunlight is collected by arranging the light condensing units, frequency division is conducted on the sunlight through the infrared separation and absorption units, visible light obtained after frequency division is used for irradiating plants on all layers of cultivation faces, ultraviolet light and infrared light are used for sterilizing a nutrient solution, frequency division utilization of solar energy is achieved, and the illumination and refrigeration energy consumption of the plant factory is reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a solar three-dimensional lighting system for a closed plant factory. Background technique [0002] The plant factory is a high-efficiency agricultural system that achieves annual continuous production of crops through high-precision environmental control in the facility. It has been recognized internationally as an advanced development form of facility agriculture for many years. [0003] The energy consumption of light sources and air conditioners in closed plant factories has always been a key restrictive factor affecting their development. A large amount of solar clean energy not only cannot be utilized by it, but also increases the cooling load of its air conditioner. In a plant factory, electric energy consumption accounts for about 52% of the operating cost, while the energy consumption of artificial light source and air conditioner accounts for 60% and 3...
