Description

Technical Field

[0001] This utility model relates to the field of plant lighting, specifically to an energy-saving plant lighting power supply system. Background Technology

[0002] With the development of modern agriculture, plant lighting technology has been widely used in agricultural facilities such as greenhouses and polytunnels. Plant lighting systems, through the illumination of light sources with specific spectra, can effectively promote plant photosynthesis, increase plant growth rate and yield, prolong flowering period, and improve fruit quality. However, traditional plant lighting systems mainly have the following problems:

[0003] First, most traditional plant lighting systems are directly connected to the power grid. When the power grid fails, the system cannot function properly, depriving plants of continuous light support during critical growth stages. Second, some lighting systems use energy-intensive incandescent lamps or other high-power light sources, which not only consume a lot of electricity but also increase the temperature inside greenhouses or polytunnels, resulting in energy waste and adversely affecting plant growth. Furthermore, existing plant lighting systems typically lack the ability to monitor and control environmental parameters, failing to adjust lighting intensity based on real-time temperature or carbon dioxide concentration, leading to resource waste or reduced photosynthetic efficiency.

[0004] In plant photosynthesis, carbon dioxide concentration is closely related to photosynthetic efficiency. When the carbon dioxide concentration in the environment is below a certain level, increasing light intensity will not further improve photosynthetic efficiency, while when the carbon dioxide concentration is too high, photosynthetic efficiency will also be inhibited. Therefore, rationally monitoring and adjusting the carbon dioxide concentration in a plant lighting system, in conjunction with adjusting light intensity, can better optimize the plant's growth environment, improve light energy utilization efficiency, and achieve the goal of energy conservation and efficiency improvement. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an energy-saving plant lighting power supply system that combines photovoltaic energy storage technology with an intelligent control module. Through photovoltaic panels, energy storage batteries, and temperature and carbon dioxide concentration sensors, it achieves automatic power supply and environmental regulation functions for the plant lighting system.

[0006] This utility model is achieved through the following technical solution: an energy-saving plant lighting power supply system, comprising:

[0007] Photovoltaic panels are used to collect solar energy and convert it into electrical energy;

[0008] A DC / DC charger is connected to the photovoltaic panel to convert the electrical energy generated by the photovoltaic panel into direct current and store it in the energy storage battery.

[0009] AC / DC chargers are used to charge energy storage batteries via the grid when there is insufficient sunlight.

[0010] An energy storage battery, connected to the DC / DC charger and the AC / DC charger, is used to store electrical energy and supply power to the plant lighting discharge system at night.

[0011] Plant lighting discharge system, including:

[0024] As a preferred technical solution, the carbon dioxide generator automatically starts according to the signal from the carbon dioxide concentration detector, releasing carbon dioxide to replenish the carbon dioxide concentration in the environment.

[0025] As a preferred technical solution, the fresh air system includes a fan and a filter. The fan is activated when the carbon dioxide concentration exceeds a set value to introduce fresh air from the outside and allow it to enter the greenhouse or shed through the filter to regulate the carbon dioxide concentration.

[0026] The beneficial effects of this utility model are: This utility model uses photovoltaic panels to collect solar energy during the day and stores the electrical energy in the energy storage battery through a DC / DC charger, so that the system can continuously provide stable power for plant lighting at night or when the power grid is out, thereby ensuring the light needs of plants in different environments.

[0027] Secondly, the system uses low-energy LED light sources and is equipped with temperature sensing modules and carbon dioxide concentration sensing modules, which can dynamically adjust the light intensity according to the real-time detected temperature and carbon dioxide concentration, thus avoiding energy waste caused by excessive lighting or excessively high ambient temperature.

[0031] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0032] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0033] like Figure 1 As shown, the present invention provides an energy-saving plant lighting power supply system, which includes a photovoltaic panel, a DC / DC charger, an AC / DC charger, an energy storage battery, a plant lighting discharge system, a temperature sensing system, and a carbon dioxide concentration detection and regulation system.

[0034] Photovoltaic panels are used to collect solar energy and convert it into electrical energy. Specifically, the photovoltaic panels convert the collected solar energy into direct current (DC), which is then transmitted to an energy storage battery via a DC / DC charger. The input terminal of the DC / DC charger is connected to the photovoltaic panel, and the output terminal is connected to the energy storage battery. The charger is used to adjust the DC voltage output by the photovoltaic panel to a suitable voltage for the energy storage battery, ensuring that the electrical energy is safely and effectively stored in the battery.

[0035] To provide sufficient power to the energy storage battery during periods of insufficient sunlight, the system also includes an AC / DC charger. The AC / DC charger connects to the power grid, drawing power from the grid at its input. When the grid experiences periods of low electricity prices, the AC / DC charger converts the grid power into a voltage suitable for the energy storage battery and charges it. Therefore, the energy storage battery not only maintains normal system operation under unfavorable lighting conditions but also effectively utilizes periods of low electricity prices, achieving cost savings.

[0036] The energy storage battery is connected to the DC / DC charger and AC / DC charger to store electrical energy provided during the day or by the power grid, and to supply power to the plant lighting discharge system at night or when the power grid fails. The energy storage battery is connected to the plant lighting discharge system to provide continuous power support to the latter, so as to ensure that the system can provide the plants with the required light under various light conditions.

[0037] Specifically, the plant lighting discharge system includes a DC / AC inverter and LED lighting equipment. The DC input terminal of the DC / AC inverter is connected to the energy storage battery, and the AC output terminal is connected to the LED lighting equipment. It is used to convert the DC power output from the energy storage battery into AC power to provide a stable AC power supply for the LED lighting equipment. The LED lighting equipment is a low-energy light source that can efficiently provide the light required for plant growth.

[0038] In this embodiment, a temperature sensing system is also provided to monitor the ambient temperature and adjust the working status of the LED lighting equipment in a timely manner. Specifically, the temperature sensing system includes a temperature detector and a control circuit. The temperature detector is used to collect ambient temperature data, and the control circuit controls the power output of the LED lighting equipment according to the temperature signal. When the ambient temperature exceeds the preset value, the control circuit will reduce the power of the LED lighting equipment to avoid excessive heat from adversely affecting plant growth and to reduce the energy consumption of the system, thereby achieving energy saving.

[0039] To further optimize the plant's growth environment, this invention also includes a carbon dioxide concentration detection and regulation system, which comprises a carbon dioxide concentration detector, a carbon dioxide generator, and a fresh air system.

[0040] The carbon dioxide concentration detector is used to monitor the carbon dioxide concentration in greenhouses or polytunnels in real time and output a detection signal. Based on the detected carbon dioxide concentration, when the carbon dioxide concentration is lower than the set value, the system will start the carbon dioxide generator. The carbon dioxide generator will automatically start according to the signal from the carbon dioxide concentration detector and release carbon dioxide to replenish the carbon dioxide concentration in the environment, ensuring that plants can carry out photosynthesis at a suitable carbon dioxide level.

[0041] When the carbon dioxide concentration exceeds the set value, the system will activate the fresh air system. The fresh air system includes a fan and a filter. The fan starts when the carbon dioxide concentration exceeds the set value, introduces fresh air from the outside, and enters the greenhouse or polytunnel after being filtered by the filter to regulate the carbon dioxide concentration. In this way, the system can automatically adjust the carbon dioxide concentration according to the needs of the plants, provide the best conditions for the plants' photosynthesis, and thus improve the plant's growth efficiency.

[0042] The energy-saving plant lighting power supply system of this utility model can use photovoltaic panels to collect solar energy during the day and store it in energy storage batteries, so that the system can still provide continuous power support for plant lighting at night or when the power grid is interrupted.

[0043] In addition, the system uses low-energy LED light sources and intelligent temperature and carbon dioxide concentration detection modules, which can dynamically adjust the light intensity according to the real-time detected temperature and carbon dioxide concentration, avoiding energy waste caused by excessive lighting or excessively high ambient temperature.

[0044] By using a carbon dioxide generator and a fresh air system in combination, the system automatically adjusts when the ambient carbon dioxide concentration is unsuitable, creating optimal growth conditions for plant photosynthesis, thereby further improving the system's energy efficiency and plant growth.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
