Description

Technical Field

[0001] A modular supplementary lighting device, system and method for LED light sources for efficient plant growth. Background Art

[0002] The growth and development process of plants is highly dependent on the lighting environment. Key parameters such as light intensity and light quality directly affect the photosynthesis, morphological development, flowering and fruiting, and ultimately the yield and quality of plants. In environments with insufficient natural light, such as winter, cloudy days, high latitudes, or closed facility agriculture, plant growth is often significantly restricted. In severe cases, this can lead to growth stagnation, yield decline, and even quality deterioration. Currently, LED fill lights have been widely used in plant growth supplementary lighting, especially in the growth process of most crops with high light requirements. However, current fill light devices usually use a fixed light source output, and the spectrum and light intensity cannot be adjusted. In addition, existing technologies are usually unable to flexibly adjust these lighting parameters, resulting in the inability of plants to obtain suitable lighting conditions, which in turn affects the growth rate and efficiency of plants.

[0003] The inventors have discovered numerous problems with current artificial plant lighting devices, systems, and methods. First, most existing lighting systems utilize a fixed light source output, with non-adjustable spectral composition and intensity, making it difficult to adapt to the diverse light quality and intensity requirements of plants at different stages of growth. Plants respond differently to light at different developmental stages. During the vegetative stage, they may require more blue light to promote leaf development, while during the flowering and fruiting stages, they rely more on red light to enhance photosynthetic product accumulation. Consequently, fixed-spectrum lighting systems often fail to provide optimal lighting conditions, impacting plant growth efficiency and quality.

[0004] Secondly, most current supplemental lighting devices lack the ability to dynamically adjust light intensity, providing only a fixed output. This rigid design makes it difficult to flexibly control light intensity based on actual needs, and can easily result in insufficient or excessive light. Insufficient light intensity can lead to inefficient photosynthesis and slow growth, while excessive light intensity can cause photoinhibition or photodamage, compromising plant health.

[0005] Furthermore, some existing fill-light devices are bulky and heavy, making them difficult to transport, install, and use in small greenhouses or homes. Furthermore, inadequate heat dissipation system design is also a common problem. If the heat generated by LED artificial light sources during prolonged operation cannot be effectively dissipated, the device will overheat, affecting light output and component lifespan, ultimately impacting the stability of the fill-light effect.

[0006] In summary, existing plant lighting supplementation technologies have shortcomings in terms of spectral adjustment flexibility, dynamic control of light intensity, equipment structure adaptability and thermal management. There is an urgent need to develop a method that can flexibly adjust light quality and intensity according to the specific needs of plants at different growth stages. Summary of the Invention

[0007] The present invention provides a modular LED light source supplemental lighting device, system, and method for efficient plant growth. This supplemental lighting device utilizes a modular design and can flexibly adjust light intensity and light quality ratio according to the needs of plants at different growth stages, providing precise lighting support, optimizing the plant's light growth environment, and promoting efficient plant growth.

[0008] The supplemental lighting device includes a modular lamp body housing multiple LED light source modules. These modules can be regulated to output spectra in different wavelengths to suit the lighting needs of plants at different growth stages. Each module adjusts its light intensity and spectral output via a control system, enabling precise light control.

[0009] Preferably, the control system includes several key components: a light quality ratio display screen that displays the light quality ratio parameters in real time; a light intensity display screen that displays the current light intensity of the lamp; and a light parameter adjustment knob on the lamp body that allows users to adjust the light intensity and light quality ratio parameters according to the different needs of the plant growth stage. The control system can adjust the light intensity and spectral output of the LED light source module based on the environmental data monitored in real time by the light intensity sensor and the light quality ratio sensor to ensure that the plant receives optimal lighting conditions at each growth stage.

[0010] The lamp body is preferably equipped with an efficient heat dissipation system, including heat sinks, heat rings, and a heat dissipation net, to optimize heat dissipation from the LED lamp beads, extend the lamp's service life, and ensure long-term stable operation. Furthermore, the LED light source module uses high-efficiency heat dissipation materials to improve the light source's luminous efficiency and thermal management performance, ensuring the stability and long-term use of the LED lamp.

[0011] This supplemental lighting system features a modular design, allowing users to flexibly combine and replace LED light source modules to adjust light intensity, coverage, and spectral output according to the needs of different plant cultivation environments. The LED light source modules connect to the power module and control system via a power interface, providing a more flexible lighting solution for plants.

[0012] This invention provides a modular supplemental lighting system for efficient plant growth using LED light sources. The system comprises a control system and a power module.

Users can adjust the output spectrum ratio and light intensity to suit the different growth stages of the plants based on the lighting requirements of the plants. The power module provides stable power to the LED light source module and supports intelligent adjustment of light intensity and spectral output.

[0013] Preferably, the control system further includes an energy-saving mode, which automatically reduces the light intensity and reduces energy consumption when the light intensity and light quality ratio meet the plant growth requirements or when the light intensity is too strong than the intensity required for plant growth.

[0014] The present invention provides a lighting method for a modular fill light with an LED light source for efficient plant growth, comprising: initializing a fill light system, obtaining the current working status of a fill light device through a control system, and setting initial lighting conditions; before planting plants, presetting the spectrum and intensity of the fill light device to adapt to the growth requirements of the plants; during the growth of the plants, using a light sensor and a light quality ratio sensor to monitor the lighting conditions in real time, and adjusting the light intensity and spectrum output based on data feedback to ensure that the plants obtain the required optimal light at each growth stage; and based on the light parameters required by the plants, accurately controlling the light intensity and light quality ratio, implementing efficient fill light, and promoting the healthy growth of the plants.

[0032] This patent does not provide prior art drawings, and the content of the prior art has been described in detail in the "Background Technology" section of the specification. DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0034] In practical applications, supplemental lighting follows the natural growth patterns of plants, providing artificial light when natural sunlight is insufficient. This approach can compensate for deficiencies in natural light, supporting plant development and growth, and thus improving economic efficiency. By strategically deploying artificial lighting, growers can ensure that plants receive the optimal spectrum and intensity required for photosynthesis and other growth-related processes, regardless of external weather conditions or geographic location. This approach is particularly beneficial in controlled environment agriculture, such as greenhouses or indoor vertical farms, where consistent and controlled lighting is crucial to maximizing crop yield and quality.

[0035] To achieve the above-mentioned purpose, the present invention provides a modular supplementary lighting device for efficient plant growth using LED light sources, comprising a lamp body 10, wherein a plurality of LED light source modules 13 are modularly arranged inside the lamp body. The core technical solution is that the device also includes: a control system 13 electrically connected to the LED light source module 13, for adjusting lighting parameters; a heat dissipation system thermally connected to the LED light source module 13; and a light intensity sensor 8 and a light quality ratio sensor 14 signal-connected to the control system. Through the coordinated work between the various systems, precise control of the plant lighting environment is achieved. The supplementary lighting device adopts a modular design and can flexibly adjust the light intensity and light quality ratio according to the needs of the plant at different growth stages, provide precise lighting support, optimize the plant growth environment, promote the healthy growth of the plant, and ultimately improve the yield and quality of the plant.

[0036] Specifically, the fill light device includes several key components: a control system on / off button 1 for turning the fill light on and off; a light quality ratio parameter display 2 located on top of the fill light device, which displays real-time light quality ratio and other lighting parameters; and a light intensity display 3 located on top of the fill light device, which displays the current light quality ratio and light intensity. By rotating the light parameter adjustment knob 4, the user can adjust the light intensity and light quality ratio parameters according to the different needs of the plant growth stage. The control system adjusts the light intensity and spectral output of the LED light source module based on real-time environmental data monitored by the light intensity sensor 8 and the light quality ratio sensor 14, ensuring that the plants receive optimal lighting conditions at each growth stage.

[0037] Specifically, the core of the control system 12 is a microcontroller (MCU, which can use an STM32 series chip). The power module 11 provides the required voltage for the MCU and the LED light source module 13. The data collected by the light intensity sensor 8 and the light quality ratio sensor 14 are input into the MCU through A / D conversion. The parameters set by the user through the light parameter adjustment knob 4 are also input into the MCU. The MCU runs a preset control program inside. According to the sensor data and user settings, it controls the drive circuit separately through multiple PWM (pulse width modulation) signals to adjust the current flowing through the LED lamp beads 17 of different colors, thereby achieving precise control of the total light intensity and spectral ratio.

[0038] Specifically, the LED light source module is connected to the power module 11 and the control system 12 via the power interface 15; the top of the fill light device is also equipped with an adjustable bracket 9, which can adjust the position of the lamp body and the lighting angle according to the planting needs of the plant to ensure that the light can evenly cover the plant growth area. The power interface 15 is used to provide stable power support for the entire fill light system to ensure the stable operation of the equipment. The light quality ratio parameter display screen 2 and the light intensity display screen 3 are used to display information such as light quality ratio and light intensity in real time. The user can accurately control the light intensity and spectrum ratio by adjusting the button 4 to adapt to the different growth needs of the plant. At the same time, the control system 12 includes an intelligent adjustment module that can adjust the light intensity and light quality ratio according to the growth stage of the plant and the real-time lighting conditions, reduce energy waste and improve lighting efficiency.

[0039] The device is equipped with an efficient heat dissipation system, including heat sinks 5, heat rings 6, and heat dissipation nets 7, which are used to optimize heat dissipation from the LED lamp beads, extend the lamp's service life, and ensure long-term stable operation. The LED light source module 13 uses high-efficiency heat dissipation materials to improve the light source's luminous efficiency and thermal management performance, ensuring the stability and long-term use of the LED lamp.

[0040] Specifically, the heat dissipation system is installed in the upper layer inside the lamp body 10. The back of the substrate of the LED lamp board 16 is tightly fitted with the large-area heat sink 5 through high thermal conductivity silicone grease. The heat sink 5 is preferably a fin-type aluminum profile. The heat dissipation ring 6 can be an annular heat pipe, whose evaporation section is in contact with the edge of the LED lamp board 16, and the condensation section is connected to the heat dissipation network 7. The heat dissipation network 7 is a metal woven mesh that covers the vents on the upper part of the lamp body 10 and dissipates heat by natural convection or forced air cooling. By adopting the heat dissipation system of the present invention, after 2 hours of continuous operation, the node temperature of the LED lamp bead is stabilized at 75°C, which is 21% lower than that of a conventional flat-plate heat dissipation device that does not adopt the present heat dissipation system (whose node temperature reaches 95°C), thereby reducing its light decay rate by about 50% and extending its expected service life by more than 30%.

[0041] The LED lighting system of the present invention, through its intelligent control system 12, modular design, and efficient heat dissipation, not only improves the plant growth environment and ensures optimal lighting conditions, but also reduces energy consumption, improves resource utilization, and thus optimizes the production process. The invention's energy-saving mode automatically reduces the device's power from 100W to 30W, saving 70% of the energy during this period compared to running the device continuously at full power.

[0042] The present invention also provides a supplemental lighting system, which includes any of the supplemental lighting devices described above and utilizes its control system, light control function, and power module to form a complete, automatically operable plant lighting solution. The system includes: a control system 12 and a power module 11. The light control system includes a light quality ratio sensor 14 and a light intensity sensor 8, which monitor the light quality ratio and light intensity of the supplemental lighting device in real time and automatically adjust the brightness of the light source according to the needs of the plants; the control system automatically adjusts the spectrum ratio and light intensity according to the lighting needs of the plants to adapt to the different growth stages of the plants; the power module 11 provides a stable power supply for the LED light source module and supports intelligent adjustment of light intensity and spectrum. The control system further includes an energy-saving mode that automatically reduces light intensity and energy consumption when the light intensity and light quality ratio meet the growth needs of the plants. Based on the growth stage of the plants and the real-time lighting conditions, the system automatically adjusts the light intensity to prevent growth hindrance caused by excessive light intensity, reduces energy waste, and improves lighting efficiency. When the total light intensity (ambient light + fill light) detected by the light intensity sensor (8) exceeds the preset plant light saturation point threshold, the control system (12) will automatically reduce the PWM duty cycle and reduce the power supply to the LED until the total light intensity falls back to the optimal range for plant growth.

[0043] The present invention further provides a light-filling method, which monitors the lighting conditions in real time through the sensor of the device, processes and judges the data by the control system, and automatically adjusts the spectrum and intensity of the LED light source module, thereby forming a closed-loop intelligent control process. The method includes:

[0046] Position adjustment step: spatially adjust the position of the light source by adjusting the module or bracket system so that the light receiving surface of the plant achieves the expected light uniformity;

[0047] The sensing monitoring step is to collect the current light intensity (PPFD) in real time through the light sensor set near the plant canopy a ) and spectral composition parameters (R:B:W a );

[0048] Error calculation and comparison steps, the control system collects the real-time illumination parameters PPFD a With target PPFD t , R:B:W a with R:B:W t By comparison, the light intensity error ΔPPFD and the spectral error vector Δλ = (ΔR, ΔB, ΔW) are calculated;

[0049] an automatic adjustment step, invoking a control algorithm (such as PID control, fuzzy control, or empirical rules) based on the error vector to calculate an adjustment value of the LED driving parameters, and outputting a current adjustment instruction to the driving circuit to adjust the output power and spectral ratio of the LEDs in each band;

[0050] The closed-loop feedback step periodically repeats steps S104 to S106 at a set time interval Δt, forming a real-time sensing-judgment-adjustment closed-loop control process to achieve dynamic and stable adjustment of the lighting environment;

[0051] Growth monitoring and maintenance steps: The plant growth status data is periodically collected through the plant monitoring system, and the control parameters are adaptively optimized based on the historical lighting records. When necessary, manual maintenance or calibration is prompted.

[0052] This design proposes a modular LED light source supplemental lighting device, system, and method for efficient plant growth. Not only is the device simple and easy to operate, it also precisely adjusts lighting conditions according to the plant's different growth stages, providing an optimal growth environment. This device offers significant advantages in improving plant yield and quality, making it particularly suitable for diverse growing environments, such as homes, greenhouses, and vertical farming, providing plants with a healthy and comfortable growth environment.
