[0030] This embodiment introduces a solar lighting method for greenhouse agriculture, which collects solar energy through solar panels and optimizes the operation of lighting equipment through intelligent control, thereby promoting plant growth, reducing energy consumption and improving agricultural production efficiency;

[0031] First, install the solar panels on the top of the greenhouse and ensure that the angle is adjustable to maximize the collection of sunlight. Further, connect the panels to the energy storage device to ensure that the solar energy collected during the day can be effectively stored. According to the scale of the greenhouse and the needs of the plants, install full-spectrum LED lights in a distributed manner. After the installation of the device, set the preset light intensity and temperature and humidity thresholds through the intelligent control system. When the environmental conditions change, the system automatically monitors and adjusts the light intensity through the light sensor to ensure the amount of light required for plant growth. Users can view and adjust the operating status of the system through the remote control platform. The system intelligently predicts and adjusts the start and operation mode of the supplementary lighting equipment based on real-time environmental parameters and weather forecasts to ensure maximum energy utilization.

[0032] The system integrates light sensors, temperature and humidity sensors, spectrum sensors, etc. through the intelligent controller. The sensors monitor the light intensity, temperature and humidity in the greenhouse in real time. The intelligent controller adjusts the brightness of the LED lamps through pulse width modulation (PWM) technology based on the sensor data and the preset light intensity threshold. When the external light is insufficient, the fill light automatically starts and adjusts to the required light intensity;

[0033] Furthermore, users can view and adjust the operating status of the system through the remote control platform. The system can intelligently predict and adjust the start-up and operation mode of the fill-light equipment according to real-time environmental parameters and weather forecasts to ensure maximum energy utilization. The intelligent control system can automatically adjust the operation of the fill-light equipment according to environmental changes to ensure the healthy growth of plants. The use of optical lenses and reflectors ensures the uniform distribution of the fill-light source and avoids uneven lighting and shadow areas.

[0034] The installation angle of the solar panel is adjustable to maximize the collection of light energy according to the incident angle of sunlight. The solar panel is connected to the supplementary lighting equipment through an energy storage device.

[0035] It should be noted that this embodiment uses a set of solar panels with adjustable installation angles, each with a power of 300W, installed on both sides of the greenhouse roof to maximize the collection of sunlight. The panels automatically adjust their angles according to the sunlight intensity and incident angle to ensure maximum light energy collection during the day.

[0036] The solar panel is connected to the energy storage device including a lithium battery pack for storing the converted electrical energy. The energy storage device has a battery capacity of 500Ah and can provide sufficient power for the supplementary lighting equipment on cloudy days or at night.

[0037] The fill light device is a full-spectrum LED lamp, which can adjust the spectral output of different wavelengths. The fill light device can automatically adjust the spectral output within the red light and blue light range according to the plant type and growth stage to promote plant photosynthesis. Red light refers to light with a wavelength between 620 and 750 nanometers (nm), and blue light refers to light with a wavelength between 450 and 495 nanometers (nm).

[0038] Full-spectrum LED lamps, these lamps can adjust the ratio of red light and blue light according to the different growth stages of plants. In different stages of plant growth, such as flowering or growth period, the system will automatically adjust the spectral output of LED lamps to promote photosynthesis and increase crop yields.

[0039] The intelligent control system includes light sensors, temperature and humidity sensors, and spectral sensors, which are used to monitor the environmental conditions in the fill light area in real time. The sensor data can automatically adjust the light intensity and start time of the fill light equipment. The intelligent control system automatically adjusts the operating status of the fill light equipment according to weather forecast information and environmental change predictions. The intelligent control system adjusts the brightness of the fill light through pulse width modulation (PWM) technology according to the preset light intensity and temperature and humidity thresholds.

[0040] The optical lens and reflector are customized according to the shape and size of the fill light area. The fill light equipment includes multiple full-spectrum LED lights, and the optical lens or reflector design is used to achieve uniform distribution of light to avoid excessive concentration of light or shadows.

[0041] Each LED luminaire is equipped with a customized optical lens and reflector to ensure even distribution of light. The design of the lens and reflector is optimized according to the crop layout in the greenhouse to avoid excessive concentration of light or shadows, ensuring that all crops can evenly receive supplementary light.

[0042] The energy storage device is used to store the electric energy converted from solar energy. The energy storage device is used to supply the power required by the supplementary lighting equipment when there is no light. The system includes a remote monitoring function, which is connected to the central control system through the Internet or local area network to realize remote inspection of the equipment and ensure the operation of the supplementary lighting system;

[0043] By utilizing solar power generation, the system reduces dependence on traditional power grids, reduces greenhouse operating costs, and reduces carbon emissions. The intelligent control system can automatically adjust the operation of the fill light equipment according to environmental changes to ensure the healthy growth of plants. The use of further optical lenses and reflectors ensures the uniform distribution of the fill light source, avoiding uneven lighting and shadow areas.

[0044] Embodiment 2: This embodiment provides a solar lighting method suitable for urban roof greening projects. The method provides additional lighting for roof green plants through efficient solar panels and intelligent control systems, especially on cloudy days or in winter, to ensure the growth needs of vegetation.

[0045] Solar panels: Each green roof project is equipped with multiple adjustable angle solar panels, each with a power of 250W. The panels are installed on both sides of the roof to maximize the use of sunlight and ensure that the system can effectively collect solar energy even in winter or on cloudy days;

[0046] Energy storage device: All solar panels are connected to a central energy storage device with a capacity of 600Ah, which can provide energy for supplementary lighting equipment in the absence of sunlight, ensuring the continuous operation of the system at night or in rainy weather;

[0047] Lighting equipment: The lighting equipment is a number of full-spectrum LED lamps, each of which can provide adjustment of the wavelength range from 400 to 700 nanometers. The LED lamps automatically adjust the spectrum output through the intelligent controller to adjust the ratio of red light and blue light according to the different growth stages of the roof green plants. The light intensity and color temperature will also be adjusted according to the growth needs of the plants;

[0048] Intelligent control system: The system includes environmental monitoring sensors such as temperature and humidity sensors, light sensors and spectrum sensors to monitor the growth environment of rooftop green plants in real time. The intelligent control system determines whether additional lighting is needed based on sensor data, and predicts lighting needs based on weather forecasts and environmental changes, and automatically adjusts the brightness and switch status of LED fill lights;

[0049] Optical lens and reflector: Each LED luminaire is equipped with a customized optical lens and reflector to ensure even light distribution. The design of the lens and reflector takes into account the specific layout of the roof greening to ensure that vegetation in different areas can receive even light;

[0050] Remote monitoring and management: The system supports remote monitoring and management. Users can view battery power, light intensity, and system operating status through mobile phone applications, and can adjust system settings as needed. The central control system will also automatically send notifications to users when equipment fails or requires maintenance.

[0051] Implementation steps: Install solar panels on the roof, ensure that the panels can be adjusted at an angle to maximize the collection of solar energy. Then, install energy storage devices and full-spectrum LED fill lights to ensure that all green areas are covered. Install temperature and humidity sensors, light sensors, etc. in the roof greening area, and monitor environmental conditions in real time through the intelligent control system. When the external light is insufficient, the LED lamps will automatically turn on and adjust the spectrum output to ensure that the plants can get the required light. Through the remote management platform, users can view the system status in real time and make adjustments. When the system detects a fault or requires maintenance, the central control system will automatically send a reminder to ensure that the system always runs efficiently.

[0052] Furthermore, by making full use of solar energy, the adjustable angle panels can maximize solar energy collection, reduce energy consumption and lower carbon footprint. The intelligent control system can automatically adjust the supplementary lighting equipment according to real-time environmental data to ensure the lighting conditions required for plant growth. The optical lens and reflector design ensures the uniformity of lighting in the roof greening area and avoids uneven lighting or shadows.

[0053] Example 3: Preventing and controlling premature flowering of short-day plants: Stevia is a short-day plant. The lower the latitude, the shorter the autumn sunlight duration. Stevia planted in Wuhan, Hubei, is equipped with 1 solar panel and 3 LED 30-watt lamps per 50 square meters, with supplementary lighting for 3 hours a day. It has been observed that the flowering period of stevia is delayed by an average of 14 days; the stevia yield (dry product) is increased by 11.5%.

[0054] Table 1 Ratio of lamps

[0055]

[0056] From the above, we can see that the lighting configuration in agricultural greenhouses is relatively high, especially for the cultivation of vegetables and flowers in greenhouses, which requires higher-power LED plant growth lights and adjusts the spectrum ratio according to the different needs of plants to ensure that the light supports the different growth stages of plants. The lighting configuration in home gardening is relatively low, especially in the growth of succulents, which emphasizes blue light as the main color to avoid excessive red light causing excessive growth. For ordinary green plants, a more balanced full spectrum is used to promote healthy growth.

[0059]

[0060] As can be seen from the table above, solar lighting technology has obvious advantages in terms of environmental protection, long-term cost operation, installation flexibility, and applicability to remote areas. It is suitable for scenarios with high demands for energy self-sufficiency and green environmental protection, such as agriculture and outdoor lighting. Its initial investment is high, but it is more economical in long-term use. Ordinary lighting technology is relatively mature in terms of simple installation, wide application range and intelligent adjustment. It is suitable for scenes such as cities or homes with stable power grid power supply, although the long-term operating cost is high and it may be restricted by the source of electricity in terms of environmental protection.
