Aiming at the problems of poor illumination uniformity and low efficiency of existing plant lamps, according to the basic principles of optics and Principle of non-imaging optics, this paper designs a hyperboloid lens module with high uniformity. The hyperboloid radian of the free-form lens is used to divide the light emitted by LED into two parts: refraction and transmission, which increases the coupling degree of light and improves the optical efficiency and uniformity of the light exit surface. In this paper, 3535 440 LEDs of 1W are used as the light source of the plant lamp. In the plant lamp with the size of 170mm×350mm, the LED light source is divided into 11 rows with 40 LEDs in each row. The light tracing simulation of the free-form lens module model of the designed plant lamp is carried out in TracePro software. The results show that when the maximum diameter of the free-form lens is 15.0mm, the height is 9.16mm and the thickness is 3.8mm, the beam angle of the plant lamp is 90, and the receiving surface is 0.5 m away from the lightemitting surface of the plant lamp, the illumination distribution with over 90% uniformity and 90% optical efficiency can be obtained in the illumination area with a diameter of 500mm×500mm.

LED can effectively promote the growth of crops and improve the yield of crops. In order to make the crops grow evenly in the agricultural greenhouse, the uniformity of illumination is very important. Because of the importance of illumination uniformity to the growth of crops, this paper intends to establish the illuminance model of light source without considering the influence factors such as the difference of each light source group and air scattering. On this basis, the reasonable layout of each light source position in the light source group is considered. Therefore, a light replenishment scheduling strategy based on the displacement of light source group is proposed in this paper Improve the uniformity of illumination in agricultural greenhouse and reduce its operation cost. Experiments show that the strategy is effective.
