[0002] In order to solve the self-power consumption problem of traditional lamp control circuits and the problem that they rely on external devices to achieve the on-off control of lamps, some improved solutions have emerged in the market, such as adding high-current switches or tactile switches. However, although the high-current switch can completely disconnect the connection between the battery and the load, it has problems such as large switch loss, high cost, and inability to charge when the lamp is in the off state. The tactile switch is prone to accidental on or off of the lamp due to accidental touch during production, packaging, or transportation, and cannot effectively solve the problem of large self-power consumption.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein are only for the purpose of describing the present utility model and are not intended to limit the present utility model.
[0021] Traditional solar lamp control circuits often directly supply power to high-current loads such as microcontroller units (MCUs) and LED lights through batteries. Although this design is simple and direct, there are obvious self-power consumption problems. When the lamp is in a non-working state (such as during the day or when manually turned off), the MCU and other control circuit components still continuously consume electrical energy, resulting in a rapid decrease in the battery power. This not only shortens the usage time of the lamp but also increases the energy consumption cost during long-term storage. In addition, traditional solar lamps usually rely on external devices such as light control sensors or remote controls to achieve the on / off control of the lamp. However, in the case of no remote control or when the light control sensor fails, users often cannot directly turn off the lamp, which not only affects the user experience but also may cause unnecessary power waste.
[0022] To solve the above problems, some improved solutions have emerged in the market, such as adding high-current switches or touch switches, etc. However, each of these solutions has its own limitations. Although the high-current switch can completely disconnect the connection between the battery and the load, it has problems such as large switching losses, high costs, and inability to charge when the lamp is in the off state. The touch switch, on the other hand, is prone to accidental activation or deactivation of the lamp due to accidental touch during production, packaging, or transportation, and cannot effectively solve the problem of high self-power consumption.
[0023] In view of this, the present utility model provides an intelligent lamp control circuit and a solar lamp. The control circuit includes a first mechanical switch, a second mechanical switch, a microcontroller unit, a field effect transistor, an LED lamp, and a first resistor. These components are combined to form an efficient and low-power consumption control system. Specifically, the microcontroller unit is respectively connected to the field effect transistor and the first mechanical switch; the first resistor is connected to the microcontroller unit; the LED lamp is connected to the field effect transistor; the second mechanical switch is connected to the first mechanical switch. Among them, the first mechanical switch can be used to control the opening and closing of the power supply path of the microcontroller unit. When the first mechanical switch is disconnected, the power supply path of the microcontroller unit is in the off state, and the power supply path is completely cut off, effectively curbing the self-power consumption phenomenon and significantly extending the battery life and storage time. At this time, the field effect transistor is disconnected and the LED lamp is turned off; when the first mechanical switch is closed, the power supply path of the microcontroller unit is in the on state, the field effect transistor is turned on, and the LED lamp is lit. In addition, the addition of the second mechanical switch adds flexibility to the control system, enabling users to turn off the lamp by directly operating the mechanical switch even without additional remote control or light control devices, improving the convenience and practicality of use. The intelligent lamp control circuit proposed by the present utility model effectively solves the problems of high self-power consumption and dependence on external devices to control the switch of the traditional lamp control circuit by optimizing the power supply path design and simplifying the operation method, achieving low energy consumption, high reliability, and convenience.
[0024] The following further elaborates on the present utility model in conjunction with the accompanying drawings.
[0025] See Figure 1 , Figure 1It is a schematic diagram of the intelligent lamp control circuit structure provided by the present utility model. The intelligent lamp control circuit includes a first mechanical switch S1, a second mechanical switch SW, a microcontroller unit U1, a field effect transistor Q1, an LED lamp, and a first resistor R3. Among them, the microcontroller unit U1 serves as the core controller and is respectively connected to the field effect transistor Q1 and the first mechanical switch S1 to jointly manage the on / off state of the LED lamp. The first resistor R3 can be used as a voltage-dividing element. One end of it is connected to the microcontroller unit U1, and the other end is grounded (GND), ensuring the stability of the circuit. The LED lamp is connected to the field effect transistor Q1, and its on / off switching is realized through the control of the field effect transistor Q1. Specifically, the first mechanical switch S1 is used to control the opening and closing of the power supply path of the microcontroller unit U1; when the first mechanical switch S1 is disconnected, the power supply path of the microcontroller unit U1 is in the off state, the field effect transistor Q1 is disconnected, and the LED lamp is turned off; when the first mechanical switch S1 is closed, the power supply path of the microcontroller unit U1 is in the on state, the field effect transistor Q1 is turned on, and the LED lamp is lit. In addition, by introducing the second mechanical switch SW and connecting it to the first mechanical switch S1, the switch can be extended to various parts of the lamp body, making the switch operation of the control circuit more flexible and meeting the requirements of different scenarios.
[0026] In a feasible embodiment, when the first mechanical switch S1 is closed, the power supply path of the microcontroller unit U1 is immediately turned on. At this time, the microcontroller unit U1 sends a high-level signal to the field effect transistor Q1 through its output terminal, prompting the field effect transistor Q1 to conduct, and then lighting up the LED lamp. In Figure 1 this process, it is manifested as the pin PWMW of U1 outputting a high level, making "V+→LED→V-" form a complete path, and the LED lamp immediately lights up.
[0027] In a feasible embodiment, when the first mechanical switch S1 is disconnected, the power supply path of the microcontroller unit U1 is cut off. At this time, the first resistor R3 pulls down the gate of the field effect transistor Q1 to the ground potential, forcing the microcontroller unit Q1 to disconnect, thereby blocking the power supply path of the LED lamp and achieving the extinguishing effect. In this state, the pin PWMW of the microcontroller unit U1 has no signal output, the field effect transistor Q1 remains off, and the LED lamp is turned off.
[0028] Furthermore, in order to optimize the circuit performance, the control circuit also introduces a second resistor R2, which is connected between the microcontroller unit U1 and the field effect transistor Q1 and is used to finely adjust the control signal.
[0029] Furthermore, the control circuit also includes a first diode D1 and a second diode D2 connected in parallel. When the first mechanical switch S1 is disconnected and the power supply path of the microcontroller unit U1 is closed, the first diode D1 and the second diode D2 provide a charging or protection path for the circuit, enhancing the robustness of the circuit.
[0030] Preferably, the first diode D1 and the second diode D2 are Schottky diodes.
[0031] Furthermore, the control circuit further includes a third resistor R1, which is connected in parallel with the first mechanical switch S1. The third resistor R1 not only has basic functions such as current limiting protection, but also can flexibly adapt to different types of controllers and different application scenarios through a short - circuit mechanism, thus ensuring the stability and safety of the circuit.
[0032] As Figure 2 shown, the present utility model also provides a solar lamp, which includes the intelligent lamp control circuit described above and a solar lamp 210. The intelligent lamp control circuit is built into the solar lamp 210. Further, the solar lamp 210 is internally provided with a battery panel and a switch controller 220, which work together to greatly improve the practicality of the lamp. Specifically, the battery panel can efficiently convert solar energy into electrical energy, which not only provides electrical energy for the intelligent lamp control circuit (including the LED lamp), ensuring the stable operation and long - term battery life of the lamp; at the same time, the switch controller 220 realizes precise regulation of the working state of the circuit by accessing a specific mechanical switch interface (such as the first mechanical switch S1 or the second mechanical switch SW) of the intelligent lamp control circuit, and users can flexibly control the turning on and off of the lamp, with simple operation and rapid response.
[0033] Furthermore, in order to enhance the practicality and installation convenience of the solar lamp, the solar lamp is also equipped with a lamp post 230 for supporting the solar lamp 210.
[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
