Embodiment 1

[0040] Embodiment 1 Laser transmitter external artificial light system

[0041] The cultivation facility in this embodiment is a plant factory on the roof of the Institute of Environmental Development, Chinese Academy of Agricultural Sciences.

[0042] The structural schematic diagram of the external artificial light system of the laser emitter of this embodiment is shown in figure 1 , consists of a laser emitter 2 arranged outside the wall with a small hole in the cultivation facility 1, and three pairs of beam-splitting prisms 3 and a laser divergence device 4 arranged in the cultivation facility 1; The optical path of 5 is arranged, and the laser beam 5 that hits it is divided into a branch laser beam 6 to shoot to the corresponding laser beam diverging device 4, and the laser beam 5 that is not split by the beam splitting prism 3 continues to shoot to the next split beam. Prism 3; each laser diverging device 4 diverges the branch laser beam 6 incident on it and then irrad...

Embodiment 2

[0052] Embodiment 2 The method for cultivating plants with the external artificial light system of laser emitter

[0053] The external artificial light system of the laser transmitter used in embodiment 1 is used to cultivate plants: the laser transmitter 2 transmits the laser beam 5 horizontally into the cultivation facility 1 through the small hole on the wall, and each beam splitting prism 3 will shoot the laser beam 5 onto it. The laser beam 5 splits a branch laser beam 6 and shoots to the corresponding laser beam diverging device 4 (laser beam diverging device A, laser beam diverging device B or laser beam diverging device C), and the unsplit laser beam 5 continues shoot to the next beam splitting prism 3; each laser diverging device 4 diverges the branch laser beam 6 that hits it and then irradiates the cultivation area 7 below it.

[0054] In this embodiment, three laser beam light source configurations are used:

[0055] a red laser beam (only red laser emitter is tur...

Abstract

The invention relates to the field of facility cultivation and particularly provides an external manual photosystem with a laser transmitter and a using method thereof. The photosystem is mainly formed by the laser transmitter arranged outside the wall, with small holes, of a cultivation facility, a plurality of pairs of light splitting prisms arranged in the cultivation facility, and a plurality of laser divergence devices arranged in the cultivation facility. The light splitting prisms are arranged along a light path for laser beams transmitted by the laser transmitter, and one branch of laser beams is separated from the laser beams radiated on the light splitting prism radiates to the corresponding laser beam divergence device. The laser transmitter of the manual photosystem is arranged outside the cultivation facility, laser converted into heat energy is small in proportion and is used, the influence on heat loads in the cultivation facility is small, and heat dissipation is not needed. According to the method, a large number of photons in the laser are concentrated into a tiny spatial range to be ejected, energy density is high, the laser has almost single wavelength, even if the laser is transmitted at a long distance, the characteristics of the strength and wave forms can still be kept, the utilization rate of light energy is high, and energy consumption in the plant cultivation process is greatly reduced.

Description

technical field [0001] The invention relates to the field of facility cultivation, in particular to an artificial light system with an external laser emitter and a method for using the same. Background technique [0002] With the development of facility agriculture in our country, artificial light is more and more widely used in the large-scale cultivation of vegetables and other crops. Its environmental factors are controllable, the land utilization rate is high, and it can be produced according to the plan. It is in line with the development of modern agriculture. The essential requirements will be an important means to solve problems such as population growth, resource shortage, new generation labor shortage, and rising food demand in the future, and it has attracted widespread attention from all over the world. [0003] At present, the artificial light sources used under different facility cultivation conditions are mainly high-pressure sodium lamps and fluorescent lamps...
