Preferably, since there is an alternation of the illumination period and the shadow period in the growth area, no matter whether the movable or fixed collecting part 200 can partially receive light, a storage battery pack 332 formed by connecting a plurality of storage battery cells in series and/or parallel may be disposed in the monitoring body to store the excess electric energy converted by the photoelectric conversion element 331 through the storage battery pack 332, so that the stored electric energy can be released by the storage battery pack 332 when the energy consumption of the collecting probe unit 220 cannot be met, so as to ensure the normal operation of the collecting probe unit 220. Further, a plurality of light reflecting members may be regularly disposed in the growth area, so that part of the light emitted from the light unit 120 to the growth area can be reflected, and thus, the backlight portion of the animal or plant located in the growth area, which cannot directly receive the light, can receive the light by the light emitted from the light reflecting member, and meanwhile, the light reflecting members at some positions may emit the reflected light to the photoelectric conversion element 331 in a manner of passing through the transparent plate 113 of the light emitting portion 100, so as to ensure that the photoelectric conversion element 331 can receive the proper light, thereby completing the photoelectric conversion. The central control unit 310 can make an operation plan and a path of the collecting unit 200 based on factors such as an illumination plan of each illumination unit 100 and/or a residual electric quantity in the storage battery pack 332, for example, when the collecting unit 200 is in a non-monitoring state, the central control unit 310 can drive the collecting moving unit 230 to drive the monitoring main body to move to a position corresponding to the illumination unit 100 with high illumination intensity, long illumination time and wide illumination wavelength range through the collecting regulation and control unit 250, so as to store more electric energy for the storage battery pack 332 in the non-monitoring state; when the collecting part 200 is in the monitoring state, the central control unit 310 can reasonably plan the monitoring path of the collecting part 200 based on the illumination plan and the current state of each illumination part 100, and the collecting mobile unit 230 responds to the control signal to realize the collection of the growth state in a manner of being matched with each illumination part 100.

According to a preferred embodiment, the central control unit 310 of the agricultural lighting device can number the divided growing areas and the corresponding illumination parts 100 to determine the types of animals and plants correspondingly arranged in each growing area; determining standard environment parameters corresponding to different growing areas based on different animal and plant species according to cloud data in the database, and correspondingly transmitting the standard illumination parameters to the corresponding illumination part 100 according to the numbers, so that the illumination regulation and control unit 130 can respond to a control signal to determine a proper light distribution scheme of an illumination unit, and then emit light rays corresponding to the parameters to the growing areas; judging the operation state of the illumination part 100 based on the relationship between the difference between the real-time environment parameter and the standard environment parameter fed back by the sensing unit 320 and the set threshold, and adjusting the illumination parameter of the illumination part 100 by driving the illumination regulation and control unit 130 when the difference caused by the illumination factor exceeds the set threshold; the operation plan and the path of the acquisition part 200 are made based on factors such as the illumination plan of each illumination part 100 and/or the residual electric quantity in the storage battery pack 332, and the driving part is driven to operate according to the preset plan and path by driving the acquisition regulation and control unit 250; the acquisition probe unit 220 of the acquisition part 200 is driven to acquire the growth state information of the animals and plants in each growth area by transmitting a control signal to the acquisition regulation and control unit 250, and information is stored and analyzed in the acquisition main body unit 210, so that the central control unit 310 can receive the current growth state of the corresponding measured animals and plants sent by the acquisition regulation and control unit 250; the reflected light collection unit can be driven to collect light rays excited by the fluorescent powder on the reflector in the growth area for cultivating plants, so that the current growth state and growth stage of the plants can be calculated through the light ray amount penetrating through the blade gaps, and the current growth state of the plants can be sent to the central control unit 310 for correction; the current growth state of the animal and plant is compared with the information in the historical growth database based on the collected information to judge whether the growth environment of the animal and plant meets the preset condition, and the illumination parameter of the illumination part 100 is adjusted by driving the illumination regulation and control unit 130 when the difference between the current growth state and the historical data information exceeds the set threshold value.
