[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0031] To solve the problems in the background technology, such as Figures 1 to 3 As shown, the utility model proposes an intelligent induction night light system, including a sensing module 1, a communication module, a driving module and a light board 4. The sensing module 1 is electrically connected to a power supply. The sensing module 1 is used to sense the heat of a human body and convert it into a pulse signal to an output end. The input end of the communication circuit 2 is connected to the output end of the sensing module 1, and is used to receive a human body sensing signal and a wireless signal output by the sensing module 1. The driving circuit 3 is electrically connected to the communication circuit 2 and the sensing module 1, and is used to receive an adjustment signal output by the communication circuit 2 and the sensing module 1; the light board 4 is electrically connected to the driving circuit 3, and is used to receive a control signal output by the driving circuit 3, and to generate a corresponding lighting effect.

[0032] It can be understood that the sensing module 1 detects changes in external factors, such as human body, light intensity or sound, through sensors, thereby triggering the turning on or off of the night light. The sensing module 1 is connected to a power supply for power supply. The sensing module 1 uses a human infrared sensor to sense human body heat in the surrounding environment. When human body heat approaches the sensing module 1, the sensing module 1 will convert the detected heat into a corresponding pulse signal and send it out through the output port. The sensor uses infrared radiation to detect human body heat. When someone approaches, the sensor will sense the change in body temperature and convert this change into an electrical signal. Then, the circuit inside the sensing module 1 will process these signals and convert them into corresponding pulse signals. These pulse signals can be transmitted through the output port of the sensing module 1 for use by the driving module, and then corresponding actions can be taken according to the signals provided by the sensing module 1, such as controlling the switching and dimming of the light, thereby realizing the adjustability of the smart sensing night light.

[0033] Among them, the communication circuit 2 can receive the data transmitted by the sensing module 1, and perform further processing and transmission. The input end of the communication circuit 2 will receive the sensing signal, and decode, process and convert it, so as to operate and transmit it. The communication circuit 2 can amplify, filter, digitize and other processing of the signal to ensure the reliability and accuracy of the signal. The communication circuit 2 has the function of wireless communication and can receive and send data through wireless signals. In this way, the output signal of the sensing module 1 can be transmitted to other devices or systems through wireless signals to realize the functions of remote control or data interaction.

[0034] Specifically, the driving circuit 3 receives and processes the adjustment signals output by the communication circuit 2 and the sensing module 1. The communication circuit 2 transmits the processed control signals to the driving circuit 3 by connecting to the driving circuit 3. These signals include instructions or data for adjusting the brightness, color or other parameters of the light. The driving circuit 3 is responsible for parsing these signals and controlling the state of the light according to the instructions. The adjustment signals output by the sensing module 1, such as human body sensing signals, are also received by the driving circuit 3. These signals are used to indicate whether the driving circuit 3 needs to control the turning on or off of the light. When the sensing module 1 detects human activity, it will be transmitted to the driving circuit 3 through a signal, thereby triggering the turning on of the light. If the sensing module 1 does not detect human activity, the driving circuit 3 can turn off the light to save energy.

[0035] Furthermore, the light board 4 is electrically connected to the driving circuit 3 to receive the control signal output by the driving circuit 3 and produce corresponding lighting effects. The light board 4 includes LED lamp beads. The driving circuit 3 will send the control signal to the LED lamp beads to change their brightness and color. The LED lamp beads are a kind of dimmable lighting device. The brightness is adjusted by changing the control of current and voltage. The desired color effect can also be produced by adjusting the brightness of LED lamp beads of different colors.

[0036] like Figure 1 As shown, in one embodiment of the present application, the communication circuit 2 has a switch module 21, and the switch module 21 serves as a part of the output end of the communication circuit 2, and is used to control the conduction and closing of the light board 4.

[0037] It can be understood that the switch module 21 is an electronic device used to control the switching state of the circuit. In the communication circuit 2, the switch module 21 is connected between the drive circuit 3 and the light board 4 as an output port. By controlling the conduction or closure of the switch module 21, the on-off state of the circuit can be controlled, thereby controlling the working state of the light board 4. When the switch module 21 is turned on, the circuit is closed, and current can flow through the switch module 21, thereby powering the light board 4 to make it work. The light board 4 can adjust the brightness and color according to the control signal of the drive circuit 3. By controlling the state of the switch module 21, the communication circuit 2 can realize the switch control of the light board 4. The user can control the opening and closing of the light board 4 through the instructions or trigger conditions sent by the communication circuit 2 to realize the control and adjustment of the light.

[0038] like Figure 1 As shown, in one embodiment of the present application, a plurality of lamp boards 4 are provided, and the plurality of lamp boards 4 are respectively connected to the output ends of the driving circuit 3 .

[0039] It can be understood that for a system including multiple light boards 4, each light board 4 will be connected to the output end of the driving circuit 3 respectively. This configuration enables each light board 4 to independently receive and respond to the control signal output by the driving circuit 3 to produce the desired lighting effect. Each light board 4 will have an interface or connection point at the position where it is connected to the output end of the driving circuit 3. The output end of the driving circuit 3 will correspondingly have multiple connection ports, one for connecting each light board 4. By connecting each light board 4 to the output end of the driving circuit 3 respectively, independent control of multiple light boards 4 can be achieved. The driving circuit 3 will send a control signal to each light board 4 through the corresponding output port, indicating its brightness, color, switch status and other information. Users can individually control each light board 4 according to needs, and realize independent adjustment and coordination of the brightness, color and other parameters of different light boards 4 to achieve richer and more diverse lighting effects.

[0040] like Figure 1 As shown, in one embodiment of the present application, the light board 4 has an NMOS tube 41, and the NMOS tube 41 is connected in series to the light board 4 and to the output end of the driving circuit 3.

[0041] It can be understood that the NMOS tube 41 is a common field effect tube, which is used to control the conduction and disconnection of the circuit. Connecting the NMOS tube 41 in series to the lamp board 4 can realize the switching function between the lamp board 4 and the driving circuit 3. By controlling the state of this switch, the on and off of the circuit can be controlled, and then the working state of the lamp board 4 can be controlled. Each lamp board 4 is connected to an NMOS tube 41, and multiple NMOS tubes 41 are connected in series. When the driving circuit 3 outputs a signal, the power supply of the lamp board 4 can be controlled by controlling the switching state of these NMOS tubes 41. When the NMOS tube 41 is in the on state, a circuit path is established between the lamp board 4 and the driving circuit 3, and current can flow through the NMOS tube 41 and the lamp board 4, so that the lamp board 4 works normally. Conversely, when the NMOS tube 41 is in the off state, the circuit is interrupted and the lamp board 4 cannot work.

[0042] like Figure 1 As shown, in one embodiment of the present application, the sensing module 1 is configured as a PIR sensor.

[0043] It can be understood that the PIR sensor is a commonly used passive sensor used to detect infrared radiation and heat changes of the human body. Based on the thermal radiation characteristics of the human body, the presence of the human body is detected by receiving changes in infrared radiation. When someone approaches the PIR sensor, the human body will emit infrared radiation, and the PIR sensor can sense the changes in this radiation. The sensor will convert this change into an electrical signal and send the signal to the drive circuit 3. By using the PIR sensor as the sensing module 1, the system can realize automatic sensing and control functions. When someone approaches the sensing area, the PIR sensor will detect the change and send a signal, and the drive circuit 3 will control the light board 4 accordingly to adjust the lighting.

[0044] Reference Figures 2 to 3 As shown, the utility model also proposes an intelligent induction night light, which includes an intelligent induction night light system. The specific structure of the intelligent induction night light system refers to the above embodiment. Since the intelligent induction night light adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the intelligent induction night light includes a shell 5 and a circuit board 51, the shell 5 is provided with a cavity, the light board 4 is integrated in the cavity, the induction module 1 covers the light-emitting side of the light board 4, the circuit board 51 is located on the side of the shell 5 close to the bottom wall, and the induction module 1, the driving circuit 3 and the communication circuit 2 are integrated in the circuit board 51.

[0045] It can be understood that the outer shell 5 of the smart sensor night light can be made of plastic or metal to protect the internal circuit and provide structural support. The shell 5 contains a cavity for installing and fixing other components; the light board 4 is the main light-emitting part of the smart sensor night light, usually including light-emitting elements such as LEDs.

The light-emitting side of the light board 4 is usually facing the outside of the shell 5 to achieve illumination; the sensing module 1 refers to a PIR sensor, which is used to detect changes in the surrounding environment. In the smart sensor night light, the sensing module 1 covers the light-emitting side of the light board 4 and triggers the turning on and off of the light by sensing human activities; the circuit board 51 is located on one side of the bottom wall of the shell 5, generally A PCB board, the circuit board 51 integrates key components such as the sensing module 1, the driving circuit 3 and the communication circuit 2. The sensing module 1, the driving circuit 3 and the communication circuit 2 work together to realize the control of the light board 4 and the communication with external devices; the driving circuit 3 is responsible for controlling the current, brightness, color and other parameters of the light board 4. It will judge when to turn on the light and control the working state of the LED according to the signal of the sensing module 1. The driving circuit 3 is responsible for controlling the current, brightness and color and other parameters of the light board 4. It will judge when to turn on the light and control the working state of the LED according to the signal of the sensing module 1. The communication circuit 2 is used for the communication between the intelligent sensing night light and other devices. It can transmit and control data with other devices wirelessly or wiredly.

[0046] In one embodiment of the present application, an inserter 511 is provided on a side of the circuit board 51 facing the bottom wall of the housing 5 , so that the circuit board 51 is fixed to the bottom wall of the housing 5 .

[0047] It can be understood that a plug-in 511 is usually provided on the side of the circuit board 51 facing the bottom wall of the shell 5 so as to fix the circuit board 51 inside the shell 5. Through the use of the plug-in 511, the circuit board 51 can be firmly connected to the shell 5, effectively preventing the circuit board 51 from shaking or displacing during use. At the same time, the design of the plug-in 511 also facilitates the maintenance and replacement of the circuit board 51, and the circuit board 51 can be easily inserted, removed or replaced.

[0048] In one embodiment of the present application, the sensing module 1 is a transparent plastic plate.

[0049] It can be understood that the transparent plastic plate can optimize the sensing effect through optical design and ensure that the light can be detected in different directions.
