[0002] Agriculture is a vital industry in my country, and promoting agricultural science and technology is a crucial task. In recent years, with the widespread application of facility agriculture such as plant tissue culture and factory-scale seedling production, the application value of artificial light sources in plant production has become increasingly prominent. The visible light spectrum, ranging from 380 to 760 nm, is involved in plant photosynthesis, primarily absorbing red and blue light. However, the ratio of red to blue light intensity required by plants varies at different growth stages; for example, germination and root growth require more blue light, while leaf and branch growth requires more red light. Existing artificial light source systems often have a fixed red-to-blue light ratio, making precise adjustment impossible to meet the light requirements of plants at different growth and development stages.

[0018] like Figs. 1 to 3 As shown, a plant growth supplemental lighting control system includes a power supply unit, a main control unit, a communication unit, and a lighting unit; the host computer or APP terminal communicates with the control unit through the communication unit; the lighting part includes several first laser lights 1 for emitting red laser and second laser lights 2 for emitting blue laser, the lighting part communicates with the control module, and the main control unit controls the working current of the first laser lights 1 and the second laser lights 2.

[0019] In this invention, the light-emitting unit is simultaneously equipped with several first laser lights 1 and second laser lights 2. The main control unit controls the operating current of the first laser lights 1 and second laser lights 2, thereby controlling their light intensity. The communication module can connect to a user's host computer or mobile app. The user can set the illumination intensity of the first laser lights 1 and second laser lights 2 via the host computer or mobile app, and can also simultaneously set the illumination intensity of the first laser lights 1 and the illumination time of the second laser lights 2. The communication module sends the user-set parameters to the main control unit, which generates control signals based on the set parameters and controls the first laser lights 1 and second laser lights 2 to emit light. By controlling the operating current of the first laser lights 1 and second laser lights 2, the light intensity of the first laser lights 1 and second laser lights 2 is adjusted, thereby adjusting the light intensity ratio of the red and blue light spectrum bands to meet the light requirements of plants at different growth stages. The power supply unit provides electrical energy for the operation of the main control unit, communication unit, and light-emitting unit.

[0020] Specifically, the main control unit includes a control module, an analog input module, and a laser light driver module. These modules, along with the communication module, are all connected to the control module. The laser light driver module drives the first laser light 1 and the second laser light 2 to emit light. The control module receives and processes signals from the communication module and generates control signals, which are then sent to the laser light driver module. The laser light driver module drives the laser lights to emit light and adjusts their intensity. The analog input module receives analog signals from external sources and transmits them to the control module via internal operational amplifier circuitry. The control module generates control signals based on the external analog inputs and executes corresponding lighting operations. The control module utilizes an IC chip.

[0021] In this embodiment, the communication module includes an RS485 module and a Bluetooth module. The Bluetooth module is used to wirelessly connect with the APP, and the RS485 module is used to connect with the host computer.

[0023] Furthermore, the lighting section also includes an LED light-emitting module 3, and the power supply unit includes an LED power supply module and an LED driver module. The main control unit also includes an analog output module, which is connected to the control module. The LED driver module is connected to the analog output module, the LED light-emitting module 3, and the LED power supply module. The LED driver module is used to drive the LED light-emitting module 3 to emit light. After receiving analog signals from external input, the analog input module sends the signals to the LED driver module through the analog output module, thereby controlling the LED light-emitting module 3 to emit light.

[0024] In this embodiment, the LED light-emitting module 3 uses a 3825 packaged surface-mount LED, and the light emitted by the LED light-emitting module 3 is warm white. The spectrum of the light generated by the LED light-emitting module 3 is close to that of sunlight, and it is used to simulate the spectrum of sunlight.

[0025] In the lighting section, the ratio of the first laser light 1 to the second laser light 2 is 3:1. The first laser light and the second laser light 2 are arranged alternately.

The first laser lamp 1 and the second laser lamp 2 are mounted on the mounting base plate 4 and located inside the isolation column 5. A light-diffusing plate 6 is provided on the isolation column 5, located above the first laser lamp 1 and the second laser lamp 2. In this embodiment, both the first laser lamp 1 and the second laser lamp 2 are TO-56 type laser lamps. The laser emitted by the first laser lamp 1 and the second laser lamp 2 has the characteristics of narrow beam and strong focusing. In plant production, the narrow beam and strong focusing characteristics can damage plants. To solve the above problems, this utility model places the first laser lamp 1 and the second laser lamp 2 inside the isolation column 5, and the light-diffusing plate 6 disperses the laser emitted by the laser lamp, making the laser more uniform and soft after irradiating the plant, increasing the irradiation area of ​​the laser, and avoiding damage to the plant.
