Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent agricultural breeding equipment technology, and in particular to a multispectral adjustable intelligent lighting system for livestock and poultry and its control method. Background Technology
[0002] In modern livestock and poultry farming, light is a crucial environmental factor affecting animal growth, reproduction, and health. Different livestock species and different physiological stages exhibit significant differences in their reliance on light duration, intensity, and spectral composition. Proper light management helps to: increase feed intake and daily weight gain, improve the stability of the reproductive cycle in female livestock, enhance immunity, and reduce stress responses and disease incidence.
[0003] Currently used aquaculture lighting systems mainly fall into the following two categories: 1. Timed white light lighting system: Most traditional livestock lighting fixtures are single color temperature, timed white light lighting equipment, which cannot dynamically adjust the light spectrum and intensity according to the actual needs of animals, nor can they adapt to the changing needs of different stages or different livestock species.
[0004] 2. Fixed-spectrum LED lighting systems: While some new LED lighting fixtures have adjustable color temperature, their control methods are simple (manual adjustment or single-chip timer control), lacking flexible programming capabilities and thus unable to achieve: The system switches between phased strategy presets and automatic execution, environmental perception (such as natural light intensity) and intelligent supplemental lighting, and differentiated control logic for multiple livestock species.
[0005] Fixed light spectrum fails to meet precise physiological needs: Most existing lighting fixtures provide a single, fixed spectrum (such as cool white light or warm white light), which cannot be dynamically adjusted according to the specific physiological needs of different livestock and poultry species (chickens, pigs, cattle, etc.) and different growth stages (brooding, rearing, egg production, pregnancy, etc.), thus restricting further improvements in production performance. Furthermore, poultry are highly sensitive to light source flicker; however, a constant current source can completely eliminate flicker.
[0006] The control methods are crude and the management efficiency is low: light intensity adjustment mostly relies on changing the bulb wattage or manually adjusting the voltage, which cannot achieve stepless dimming; light duration control relies on simple mechanical timers, which cannot execute complex, multi-period light programs. Management is time-consuming, labor-intensive, and lacks accuracy.
[0007] Lack of intelligent feedback and poor environmental stability: Existing systems cannot sense the actual light intensity inside the enclosure, and are especially unable to cope with interference from changes in natural light (such as cloudy days during the day and supplemental lighting at night). The inability to achieve closed-loop control of "setting-monitoring-compensation" leads to insufficient daytime light or energy waste, affecting breeding outcomes.
[0008] Highly specialized, lacking versatility, and costly: Optimized lighting solutions for different livestock or different stages often require different specialized hardware. This results in a wide variety of equipment models, increasing the complexity and cost of production, procurement, inventory, and maintenance, making it difficult to promote and apply on a large scale.
[0009] Low energy efficiency and limited functionality: Traditional incandescent and fluorescent lamps consume a lot of energy and have a short lifespan. Even when replaced with LED lights, they are mostly single-function lighting fixtures, lacking the remote centralized monitoring, data analysis, and intelligent decision-making capabilities that can be formed by combining with Internet of Things (IoT) technology, thus failing to achieve true intelligent management.

The LED chips for each channel are evenly and crosswise distributed on the substrate. Each channel is connected to an independent high-frequency PWM constant current drive circuit (located within the power supply and drive module) to receive control signals and drive the corresponding LED array for stepless dimming.

[0052] Receive ambient light intensity data from the environmental sensing unit (light sensing module, such as a light sensor).
[0053] The ambient light intensity data is compared with the target light intensity of the current strategy. If it is lower than the target value, the compensation value is automatically calculated through a closed-loop control algorithm such as PI control algorithm. Based on the RTC clock (clock module), the corresponding high-frequency PWM control signal is generated and sent to the corresponding drive circuits of the power supply and drive module in the multispectral lighting unit, i.e., the LED drive circuit, to drive the LED module in the multi-channel light source module to achieve automatic stabilization and compensation of light intensity.

[0058] It has the ability to control time periods and simulate rhythms: the control unit can automatically execute the lighting strategy on an hourly, daily or weekly basis to realize the simulation of natural day and night rhythms and light-induced estrus in livestock.
[0059] Environmental sensing and automatic supplemental lighting mechanism: The built-in light sensing module can sense the intensity of natural light in the barn in real time and automatically determine whether to supplement light in open barns to avoid excessive lighting or insufficient light, thereby improving energy efficiency and comfort.
[0060] Unified module + multi-species adaptation: All lighting hardware modules are consistent, and different livestock and poultry species can be applied by simply switching the control logic through software configuration, which facilitates standardized production, installation and subsequent maintenance.
[0061] Strong remote management and programmability: It supports remote programming and control via host computer / mobile terminal, allowing users to freely configure lighting strategies and deploy them remotely, thereby improving the level of intelligent management.
[0062] Taking the reproductive stages of female rabbits in large-scale rabbit farms as an example, especially in estrus synchronization management, mating preparation, and early pregnancy, the lighting design is shown in Table 1, and the specific effects are as follows. Figure 3 .

When the light intensity was controlled at 70 lux, the conception rate of factory-farmed rabbits such as Ira rabbits increased by 18.45%, with a litter size of 8.39±0.24 kits. Red light also promoted the expression of FSHR, LHR, β-EP, and 5-HT, and reduced melatonin synthesis, which is beneficial for ovulation and implantation.

[0067] Fattening period (22 days - slaughter): Blue and white, 20% weight gain on day 49, 3-10 lux to minimize stress; optimize feed conversion ratio for better meat quality.
[0068] Phased management of laying hens: Brooding period (0-6 weeks): Blue or green, 20-40 lux to stimulate activity and visual development. Energy saving of 80-85% compared to incandescent bulbs. Blue or green: 10-15% higher body weight compared to white bulbs. Calms flocks, reduces stress, improves feed conversion rate by 5-10%, and reduces mortality by 5-8%.
[0069] Growing period (7-18 weeks): Blue / green blend; gradually introduce red for reproductive preparation; avoid pure red to minimize aggression. Moderate: 10-20 lux to balance growth and stress. Promotes weight gain and skeletal development; improves feed efficiency. Improves uniformity by 5-10% and saves 70-80% on energy. Calms flocks, enhances immunity, increases weight gain by 8-12%, and improves feed conversion ratio by 5%.
[0070] During the laying period (18 weeks+): Use red or red-white mixtures for stimulation, 5-15 lux, to minimize stress while maintaining production; avoid high positions to prevent aggression. Optimize egg production and quality (size, shell strength); improve FCR and reduce mortality. Increase egg production rate by 5-10%, increase egg production by 10%, and save 85% on energy.

Specifically, this includes: Based on the instructions input by the external user interaction unit, the lighting strategy for the corresponding livestock and poultry species is retrieved from the lighting strategy database.
