[0029] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0030] Reference will be made below to Figure 1 - Figure 2 to describe the plant supplementary lighting device 1 of the embodiments of the present utility model.

[0031] As Figure 1 shown, it is a structural block diagram of a plant supplementary lighting device according to a specific embodiment of the present utility model. The plant supplementary lighting device 1 of the embodiments of the present utility model includes a light-emitting circuit 2, a detection circuit 4, and a main control circuit 3. Among them, the detection circuit 4 is used to detect temperature data and / or light intensity data, and the main control circuit 3 is respectively connected to the detection circuit 4 and the light-emitting circuit 2, and is used to receive the temperature data and / or light intensity data and output a power adjustment signal for the light-emitting circuit 2, where the power adjustment signal corresponds to an adjustment signal when the temperature data is higher than a preset temperature threshold.

[0032] In the embodiment, as Figure 1As shown in the figure, the plant light supplement device 1 includes a light-emitting circuit 2, a detection circuit 4, and a main control circuit 3. Among them, the detection circuit 4 is used to detect temperature data and / or light data. For example, it detects the operating temperature data and ambient temperature data of the light-emitting circuit 2, and detects the light data of the plant environment. The main control circuit 3 is respectively connected to the detection circuit 4 and the light-emitting circuit 2. The detection circuit 4 transmits the detected data to the main control circuit 3 in real time. The main control circuit 3 outputs a power adjustment signal for the light-emitting circuit according to the temperature data and / or light data received in real time. Among them, the power adjustment signal corresponds to the adjustment signal when the temperature data is higher than the preset temperature threshold.

[0033] For example, the main control circuit 3 detects the operating temperature of the light-emitting device in the light-emitting circuit 2, sets the preset temperature threshold for high-temperature warning. When the temperature data received by the main control circuit 3 is higher than the preset temperature threshold, it outputs a power adjustment signal to timely reduce the power consumption of the light-emitting device in the light-emitting circuit 2, ensuring that the light-emitting device will not be in an over-temperature operating state for a long time. By the power adjustment signal, the performance of the light-emitting device is improved, which is beneficial to extending the service life of the plant light supplement device and improving the utilization rate of power consumption.

[0034] According to the plant light supplement device 1 of the embodiment of the present invention, in this device, the main control circuit 3 is respectively connected to the detection circuit 4 and the light-emitting circuit 2. By setting the detection circuit 4 to detect temperature data and / or light data, the main control circuit 3 receives the temperature data and / or light data transmitted back by the detection circuit 4 in real time, and outputs a power adjustment signal for the light-emitting circuit 2. By the power adjustment signal, the performance of the light-emitting device is improved, which is beneficial to extending the service life of the plant light supplement device and improving the utilization rate of power consumption.

[0035] In some embodiments, as Figure 2 shown, it is the structural block diagram of the plant light supplement device of another specific embodiment of the present invention. The detection circuit 4 includes a first temperature detection sub-circuit 11 and a second temperature detection sub-circuit 12. Among them, the first temperature detection sub-circuit 11 is connected to the main control circuit 3 and is used to detect the operating temperature of the light-emitting circuit 2. The second temperature detection sub-circuit 12 is connected to the main control circuit 3 and is used to detect the ambient temperature where the plant is located.

[0036] In the embodiment, as Figure 2As shown, the detection circuit 4 includes a first temperature detection sub-circuit 11 and a second temperature detection sub-circuit 12. Among them, the lighting circuit 2 contains a light-emitting device. The first temperature detection sub-circuit 11 is connected to the main control circuit 3 to detect the operating temperature of the lighting circuit 2, for example, to detect the operating temperature of the light-emitting device in the lighting circuit 2. The second temperature detection sub-circuit 12 is connected to the main control circuit 3 and is used to detect the ambient temperature of the plant, so that the first temperature detection sub-circuit 11 and the second temperature detection sub-circuit 12 will output corresponding temperature data according to the detected temperature and transmit the temperature data back to the main control circuit 3 in real time.

[0037] In some embodiments, as Figure 2 shown, the detection circuit 4 further includes a light detection sub-circuit 10, which is connected to the main control circuit 3 and is used to detect the ambient light data of the plant.

[0038] In an embodiment, as Figure 2 shown, the detection circuit 4 further includes a light detection sub-circuit 10, which is connected to the main control circuit 3 and is used to detect the ambient light data of the plant, such as the light intensity, and transmit the detected light data back to the main control circuit 3 in real time, so that the main control circuit 3 can make corresponding adjustments according to the received light data, providing a data basis for solving the problem that in the related art, the light source output by the supplementary light control circuit is single and fixed, and cannot reasonably meet the light conditions required during the growth process of plants, resulting in an unsatisfactory cultivation effect on plants.

[0039] In some embodiments, as Figure 2 shown, the first temperature detection sub-circuit 11 and the second temperature detection sub-circuit 12 include a thermistor and a first resistor connected in series.

[0040] In an embodiment, temperature detection is a method of measuring the surface or internal temperature of an object, which can be carried out in various ways. For example, a thermistor and a first resistor are connected in series to form a voltage divider, which serves as a thermistor circuit. A thermistor circuit is a circuit that uses the temperature-sensitive characteristic of a thermistor to detect and monitor temperature; a thermistor is a special resistor device whose resistance value changes with temperature. According to different temperature coefficients of the thermistor, it can be divided into two types: negative temperature coefficient and positive temperature coefficient. In a temperature detection circuit, a negative temperature coefficient thermistor is more common, and its resistance value decreases as the temperature increases; when the temperature changes, the change in the resistance value of the thermistor will cause a change in the output voltage of the voltage divider.

[0041] In some embodiments, as Figure 2 shown, the temperature data includes ambient temperature and operating temperature, and the light data includes ambient light data. The main control circuit 3 is further used to receive the ambient temperature, operating temperature, and ambient light data and output a light data adjustment signal for the lighting circuit 2.

[0042] In an embodiment, the temperature data includes the ambient temperature and the operating temperature, wherein the ambient temperature and the operating temperature are converted into a pressure difference value through the above-mentioned thermistor circuit and transmitted back to the main control circuit 3 in real time as temperature data.

[0043] For example, as Figure 2 shown, a first temperature detection sub-circuit 11 is placed near the light-emitting device in the light-emitting circuit 2, and a second temperature detection sub-circuit 12 is placed near the plant. During operation, the first temperature detection sub-circuit 11 converts the detected operating temperature of the light-emitting device into a pressure difference value through the thermistor circuit, and the second temperature detection sub-circuit 12 converts the detected ambient temperature of the plant into a pressure difference value. The first temperature detection sub-circuit 11 and the second temperature detection sub-circuit 12 transmit the pressure difference value back to the main control circuit 3 in real time as temperature data, and the main control circuit 3 receives the temperature data so that the main control circuit 3 can make corresponding adjustments according to the received temperature data.

[0044] The ambient light data comes from the detection of the environment where the plant is located by the light detection sub-circuit 10. Light detection usually uses a light sensor. A light sensor is a sensor that detects the light intensity and converts it into an electrical signal output. It is widely used in various occasions, including environmental light monitoring, automatic lighting control, photography, plant growth control, solar energy monitoring, industrial automation, etc. The working principles and types of light sensors are diverse. For example, a photoresistor and a second resistor are connected in series to form a voltage divider to realize light detection as a photoresistor circuit. Among them, the photoresistor is made of semiconductor material, and its working principle is based on the photoelectric effect of the semiconductor. In the semiconductor material, light energy can excite electrons to jump from the valence band to the conduction band, thereby increasing the number of free electrons and causing the resistance value to decrease. When the light intensity increases, the number of excited electron-hole pairs increases, and the resistance value decreases accordingly. When the light weakens, the number of excited electron-hole pairs decreases, and the resistance value increases. When the light changes, the change in the resistance value of the photoresistor will cause a change in the output voltage of the voltage divider.

[0045] The ambient light where the plant is located is converted into a pressure difference value through the above-mentioned photoresistor circuit and transmitted back to the main control circuit 3 in real time as ambient light data. For example, a light detection sub-circuit 10 is placed near the plant. During operation, the light detection sub-circuit 10 converts the ambient light where the plant is located into a pressure difference value through the photoresistor circuit and transmits it back to the main control circuit 3 in real time as ambient light data.

[0046] The main control circuit 3 calculates and compares the working state of the LED (Light Emitting Diode) light source 14 in the real-time preset light-emitting circuit 2 based on the received ambient temperature and ambient light data, and outputs a light data adjustment signal for the light-emitting circuit 2. The light data adjustment signal includes adjusting the light intensity and light color of the LED in the light-emitting circuit 2 in real time, so as to provide a flexible output light source, reasonably meet the required light conditions during the plant growth process, and improve the cultivation effect of the plants.

[0047] In some embodiments, as Figure 2 shown, the plant supplementary lighting device further includes a touch circuit 13, and the touch circuit 13 is connected to the main control circuit 3 for displaying and controlling temperature data and / or light data.

[0048] In an embodiment, as Figure 2 shown, the touch circuit 13 includes a touch screen. The touch screen is a display screen with touch sensing function, which can realize input commands and interactions through touch operations of objects such as fingers or styli on the screen surface, greatly improving the convenience and intuitiveness of human-computer interaction, and is widely used in various electronic products and information devices. The core of the touch circuit 13 design is to convert the user's touch operation into an electronic signal so that the device can recognize and respond.

[0049] For example, the touch circuit 13 is composed of a touch sensor, a signal conditioning circuit, an analog-to-digital conversion circuit, a controller, a driving circuit and a capacitive touch screen. The touch sensor is used to detect touch actions; the signal conditioning circuit amplifies and filters the sensor signals; the analog-to-digital conversion circuit converts the analog signals into digital signals; the controller receives and processes the digital signals and executes corresponding operations; the driving circuit drives the touch screen to display; the capacitive touch screen utilizes the conductivity of the human body, and a layer of transparent conductive material such as ITO (Indium Tin Oxide) is covered on the screen surface. When a finger touches the screen, a capacitor will be formed, and the controller determines the touch position by detecting the change of the capacitor.

[0050] The plant supplementary lighting device further includes a touch circuit 13, and the touch circuit 13 is connected to the main control circuit 3. The above touch circuit 13 can be used to realize human-computer interaction. The capacitive touch screen in the touch circuit 13 can display the detected temperature data and / or light data in real time, and control the temperature data and / or light data, enabling the user to clearly and intuitively master the temperature data and / or light data related to plant growth.

[0051] In some embodiments, as Figure 2 shown, the touch circuit 13 is also used to receive the set light data and output a light data adjustment signal corresponding to the set light data.

[0052] In an embodiment, as Figure 2 shown, the set light data is set according to usage requirements. The above touch circuit 13 can also receive the set light data and output a light data adjustment signal corresponding to the set light data. The light data adjustment signal, for example, manually adjusts the light intensity and light color according to the set light data through the capacitive touch screen in the touch circuit 13, so as to provide a flexible output light source, reasonably meet the light conditions required during the plant growth process, improve the cultivation effect of plants, and enhance the user experience.

[0053] In some embodiments, as Figure 2 shown, the light-emitting circuit 2 includes an LED light source 14, a modulation sub-circuit 15, and a filtering sub-circuit 16. Among them, the LED light source 14 is used to output the light data required by plants; the modulation sub-circuit 15 is connected to the LED light source 14; the filtering sub-circuit 16 is connected to the modulation sub-circuit 15.

[0054] In an embodiment, as Figure 2 shown, the light-emitting circuit 2 includes an LED light source 14, a modulation sub-circuit 15, and a filtering sub-circuit 16, etc. The LED light source 14 can output the light data corresponding to the adjustment signal, such as the light intensity and light color corresponding to the adjustment signal. Among them, the LED in the LED light source 14, that is, the light-emitting device, is a solid-state semiconductor device that can directly convert electrical energy into light energy when current passes through. The LED has the advantages of energy saving and high efficiency, long life, fast response, environmental protection, rich colors, easy control, small volume, good color rendering, etc. For example, LED lamp beads covering the entire visible light spectrum of 410 - 700 nm are used, and the number can be determined according to the power required for actual use; the modulation sub-circuit 15 is connected to the LED light source 14 to realize the function of controlling the light-emitting characteristics of the LED, including brightness, color, flicker, etc. For example, the PWM modulation method is used to control the brightness by adjusting the on-off time ratio of the LED, that is, the duty cycle. Because the human eye is not very sensitive to rapidly changing brightness, a smooth dimming effect can be achieved. By adjusting the brightness ratio of the combination of red, green, and blue LEDs, a wide range of colors can be generated; the filtering sub-circuit 16 is connected to the modulation sub-circuit 15. The filtering sub-circuit 16 is composed of resistors and capacitors and can further smooth the DC voltage, mainly used to reduce or eliminate unwanted signal components to avoid affecting performance due to voltage fluctuations.

[0055] In some embodiments, as Figure 2 shown, the plant supplementary lighting device 1 further includes a power supply circuit 17, which is respectively connected to the light-emitting circuit 2, the detection circuit 4, and the main control circuit 3, and is used to supply power to the light-emitting circuit 2, the detection circuit 4, and the main control circuit 3.

[0056] In an embodiment, as Figure 2As shown, the power supply circuit 17 converts the external power supply into the voltage and current required by each internal module. For example, it converts the external power supply into the voltage and current required by the lighting circuit 2, the detection circuit 4, and the main control circuit 3. It is usually composed of an input filter, a voltage conversion circuit, a feedback network, a protection circuit, an output filter, etc. to achieve functions such as voltage conversion, voltage stabilization, and protection.
