[0037] Reference Figure 1 , Figure 1: is a circuit diagram of an intelligent sensor lamp according to an embodiment of the present invention. It can be understood that the intelligent sensor lamp of the present invention includes a sensor module 100; a control module 200; and a lighting module 300. The lighting module 300 and the sensor module 100 are connected in parallel to one end of the control module 200. The sensor module 100 is used to obtain and output a sensing signal to the control module 200. The control module 200 is used to receive the sensing signal and output a control signal to the lighting module 300 in response. The lighting module 300 is used to receive the control signal and perform a start operation according to the control signal.

[0038] It should be noted that the present invention only has positive and negative outputs after the control module 200, and the lighting module 300 and the sensor module 100 are both connected in parallel to the positive and negative lines of the control module 200. The sensor module 100 includes a sensor PIR, which is used to sense changes in the external environment and determine whether the change in the external environment is a person approaching or other circumstances. If the sensor PIR determines that a person is approaching, the sensor module 100 outputs a sensing signal corresponding to the determination result. If it is other circumstances, the sensor PIR determines that no one is present, and the sensor module 100 outputs a corresponding sensing signal. In actual use, when the smart sensor lamp of the present invention detects a change in the external environment, such as the sensor module 100 sensing a person, it will output a corresponding sensing signal, so that the control module 200 connected to the sensor module 100 receives the sensing signal, controls the lighting module 300 connected in parallel with the sensor module 100, receives the control signal sent by the control module 200, and performs the power-on operation. By connecting the lighting module 300 and the sensor module 100 in parallel to one end of the control module 200, the embodiment of the present invention can control the lighting module 300 without requiring additional wiring for the sensor module 100, thus simplifying the wiring of the circuit module. Furthermore, the smart sensor light of the present invention can be applied to wardrobe lights. By simplifying the wiring of the sensor module 100 and the control module 200, the present invention can reduce the difficulty of wardrobe assembly. Furthermore, when a wardrobe light problem occurs, the wardrobe must be disassembled for repair. This simplified circuit wiring reduces the installation and maintenance costs of the wardrobe light.

[0039] It should be noted that the statement in the present invention that “the smart sensor lamp of the present invention can be applied to wardrobe lamps” is only for the purpose of better illustrating the working process of the smart sensor lamp of the present invention and does not constitute a limitation of the present invention. It can be understood that the smart sensor lamp of the present invention can be applied to wardrobe lamps as well as other scenarios.

[0040] It should be noted that the sensor PIR of the present invention can be an infrared sensor, or a temperature sensor or other types of sensors. The present invention does not specifically limit the type of sensor PIR. It only needs to be able to detect changes in the external environment and output corresponding sensing signals according to the changes in the external environment.

[0041] It should be noted that the main control circuit 220 of the present invention implements signal processing for each module based on a program.

[0042] Reference Figures 2 to 5 It should be noted that the control module 200 also includes a sensing detection circuit 210 and a main control circuit 220. The lighting module 300 and the sensor module 100 are connected in parallel to the first output terminal OUT of the main control circuit 220. The input terminal of the sensing detection circuit 210 is connected to the first output terminal OUT, and the output terminal of the sensing detection circuit 210 is connected to the first input terminal IN of the main control circuit 220. The sensor module 100 is used to obtain and output a sensing signal to the sensing detection circuit 210. The sensing detection circuit 210 is used to receive the sensing signal and output the sensing detection signal to the main control circuit 220 in response. The main control circuit 220 is used to receive the sensing detection signal and output a control signal to the lighting module 300 in response.

[0043] It should be noted that the main control circuit 220 includes a first input terminal IN, a first output terminal OUT, a second output terminal OUT2, a ground terminal GND, a reset terminal RSET, and a power supply terminal VCC. The output terminal of the sensing detection circuit 210 is connected to the first input terminal IN of the main control circuit 220; the lighting module 300 and the sensor module 100 are connected in parallel to the first output terminal OUT of the main control circuit 220, and the first output terminal OUT is also connected to the input terminals of the sensing detection circuit 210 and the lighting power control circuit 230; the second output terminal OUT2 of the main control circuit 220 is connected to the input terminal of the sensor power control circuit 240; the ground terminal is connected to ground; the reset terminal RSET is connected to the reset circuit; and the power supply terminal is connected to a 5V power supply. The reset circuit includes a fifth capacitor C5 and a tenth resistor R10. One end of the fifth capacitor C5 is grounded, and the other end of the fifth capacitor C5 is connected to one end of the tenth resistor R10. The other end of the tenth resistor R10 is connected to the 5V power supply. The reset terminal RSET is connected in parallel to one end of the fifth capacitor C5.

[0044] It will be understood that the first input terminal IN is used to receive the sensing detection signal from the sensing detection circuit 210, and the main control circuit 220 controls the corresponding port to output the corresponding signal based on the sensing detection signal received at the first input terminal IN. According to one embodiment of the present invention, when the sensing detection signal is at a high level, the main control circuit 220 controls the second output terminal OUT2 to output a high level to the sensor power control circuit 240, that is, outputs the sensor power control signal to the sensor power control circuit 240; when the sensing detection signal is at a low level, the main control circuit 220 controls the first output terminal OUT to output a high level to the lighting power control circuit 230, that is, outputs the lighting power control signal to the lighting power control circuit 230.

[0045] It should be noted that the sensor module 100 , the sensing detection circuit 210 , the lighting power control circuit 230 , the sensor power control circuit 240 and the lighting module 300 are all connected in parallel on a circuit with only two positive and negative lines.

[0046] According to one embodiment of the present application, referring to Figure 8 , Figure 8 This is a control flow chart of the main control circuit 220 of the smart sensor lamp according to an embodiment of the present invention. The second output terminal OUT2 of the main control circuit 220 outputs a high-level sensor power control signal, turning on the sensor power control circuit 240 and the sensor PIR. When the sensor PIR turns on and begins detecting changes in the external environment, the second output terminal OUT2 of the main control circuit 220 outputs a low-level sensor power control signal, and the first output terminal OUT outputs a low-level lighting power control signal, turning off the sensor power control module 240 and the lighting power control module 230. At this time, only the sensing signal output by the sensor PIR is on the line. Specifically, when the sensor PIR senses a person, the first input terminal IN of the main control circuit 220 receives a low-level sensing detection signal, causing the first output terminal OUT to output a high-level lighting power control signal, thereby turning on the lighting module 300. When the sensor PIR does not sense a person during subsequent sensing processes, the first input terminal IN of the main control circuit 220 receives a high-level sensing detection signal, causing the first output terminal OUT to output a low-level lighting power control signal, thereby turning off the lighting module 300. Specifically, in order to enable the sensor module to continuously monitor changes in the external environment, the second output terminal OUT2 also outputs a high-level sensor power control signal, thereby turning on the sensor module 100 .

[0047] According to one embodiment of the present invention, when the smart sensor lamp of the present invention detects a change in the external environment, the sensor module 100 senses the presence of a person and outputs a sensing signal. When the sensor module 100 is sensing and detecting, the first output terminal OUT and the second output terminal OUT2 respectively output a low-level lighting power control signal and a low-level sensor power control signal, so that the lighting power control circuit 230 and the sensing power control circuit 240 are in the off state, and only the sensing signal output by the sensor PIR is on the line. At this time, the sensing detection circuit 210, which is also connected in parallel to the first output terminal OUT, receives a high-level sensing signal and, in response, outputs a low-level sensing detection signal to the first input terminal IN of the main control circuit 220. The main control circuit 220 controls the first output terminal OUT to output a high-level lighting power control signal to the lighting power control circuit 230. When the sensor module 100, which is connected in parallel to the first output terminal OUT of the main control circuit 220, senses that no one is present, it outputs a sensing signal, causing the sensing detection circuit 210, which is also connected in parallel to the first output terminal OUT, to receive a low-level sensing signal and, in response, output a high-level sensing detection signal to the first input terminal IN of the main control circuit 220. The main control circuit 220 controls the second output terminal OUT2 to output a high-level sensor power control signal to the sensor power control circuit 240.

[0048] It should be noted that when the external environment does not change, the main control circuit 220 controls the first output terminal OUT to output a low-level lighting power control signal to the lighting power control circuit 230. Because the lighting power control signal is at a low level, the lighting power is turned off, and the lighting module 300 does not perform the start-up operation. At the same time, the main control circuit 220 also controls the second output terminal OUT2 to output a high-level sensor power control signal to the sensor power control circuit 240. Because the sensor power control signal is at a high level, the sensor power is turned on, so that the sensor module 100 still maintains normal operation.

[0049] It should be noted that the control module 200 also includes a lighting power control circuit 230, the lighting module 300 and the sensor module 100 are connected in parallel to the output end of the lighting power control circuit 230, the input end of the sensing detection circuit 210 is connected to the output end of the lighting power control circuit 230, and the input end of the lighting power control circuit 230 is connected to the first output end OUT of the main control circuit 220; the main control circuit 220 is used to receive the sensing detection signal and respond by outputting the lighting power control signal to the lighting power control circuit 230, and the lighting power control circuit 230 is used to receive the lighting power control signal and respond by outputting the control signal to the lighting module 300.

[0050] It is understood that when the sensor module 100 is performing sensing detection, the first output terminal OUT and the second output terminal OUT2 respectively output a low-level lighting power control signal and a low-level sensor power control signal, causing the lighting power control circuit 230 and the sensor power control circuit 240 to be in a disabled state, with only the sensing signal output by the sensor PIR on the line. When the sensor module 100 senses a person, it outputs a sensing signal to the sensing detection circuit 210. The sensing detection circuit 210 outputs a corresponding sensing detection signal to the main control circuit 220 based on the sensing signal. The main control circuit 220 controls the first output terminal OUT to output the lighting power control signal. The input of the lighting power control circuit 230 is connected to the first output terminal OUT of the main control circuit 220 to receive the high-level lighting power control signal output by the first output terminal OUT. Because the lighting module 300 and the sensor module 100 are connected in parallel to the output terminal of the lighting power control circuit 230, the lighting power control circuit 230 responds to the lighting power control signal and outputs a control signal to the lighting module 300, causing the lighting module 300 to receive the control signal and perform the power-on operation.

[0051] It should be noted that, in the case where the first electric control element is a transistor, that is, the first port of the first electric control element is the base, the second port of the first electric control element is the collector, and the third port of the first electric control element is the emitter, the connection relationship is as follows: the lighting power control circuit 230 includes a twelfth resistor R12, a fifth transistor Q5, a sixth resistor R6 and the first electric control element Q1, one end of the twelfth resistor R12 is connected to the first output terminal OUT of the main control circuit 220, and the other end of the twelfth resistor R12 is connected to the base of the fifth transistor Q5. The emitter of the fifth transistor Q5 is grounded, the collector of the fifth transistor Q5 is connected to one end of the sixth resistor R6, the other end of the sixth resistor R6 is connected to the base of the first electronically controlled element Q1, the emitter of the first electronically controlled element Q1 is connected to the lighting power supply, the lighting module 300 and the sensor module 100 are connected in parallel to the collector of the first electronically controlled element Q1; wherein, one end of the twelfth resistor R12 is the input end of the lighting power supply control circuit 230, and the collector of the first electronically controlled element Q1 is the output end of the lighting power supply control circuit 230.

[0052] According to one embodiment of the present invention, when the sensor module 100 is performing sensing detection, the first output terminal OUT and the second output terminal OUT2 respectively output a low-level lighting power control signal and a low-level sensor power control signal, causing the lighting power control circuit 230 and the sensing power control circuit 240 to be in a disabled state, with only the sensing signal output by the sensor PIR being present on the circuit. When the sensor module 100 senses a person, the sensing detection circuit 210 outputs a low-level sensing detection signal to the first input terminal IN of the main control circuit 220. In response to the low-level sensing detection signal, the main control circuit 220 causes the first output terminal OUT to output a high-level lighting power control signal. In response to the lighting power control signal, the first electronic control element Q1 of the lighting power control circuit 230 turns on, enabling the lighting power supply to output a 12V voltage to the lighting module 300, i.e., outputting a control signal. At this point, the voltage on the circuit is 12V, and the lighting module 300 turns on in response to the control signal.

[0053] It should be noted that, referring to Figure 3 The lighting power control circuit 230 of the present invention also includes a thirteenth resistor R13 and an eleventh resistor R11. One end of the thirteenth resistor R13 is grounded, and the other end is connected to the base of the fifth transistor Q5. One end of the eleventh resistor R11 is connected to the collector of the fifth transistor Q5, and the other end is connected to the emitter of the first electronic control element Q1.

[0054] It should be noted that the control module 200 also includes a sensor power control circuit 240, and the lighting module 300 and the sensor module 100 are connected in parallel to the output end of the sensor power control circuit 240; the input end of the induction detection circuit 210 is connected to the output end of the sensor power control circuit 240, and the input end of the sensor power control circuit 240 is connected to the second output end OUT2 of the main control circuit 220; the main control circuit 220 is used to receive the induction detection signal and output the sensor power control signal to the sensor power control circuit 240 in response, and the sensor power control circuit 240 is used to receive the sensor power control signal and output the power supply signal to the sensor module 100 in response.

[0055] It can be understood that when the sensor module 100 is performing sensing detection, the first output terminal OUT and the second output terminal OUT2 respectively output a low-level lighting power control signal and a low-level sensor power control signal, so that the lighting power control circuit 230 and the sensing power control circuit 240 are in a closed state, and only the sensing signal output by the sensor PIR is on the line. When the sensor module 100 does not sense a person, it outputs a sensing signal to the sensing detection circuit 210. The sensing detection circuit 210 outputs a corresponding sensing detection signal to the main control circuit 220 based on the sensing signal. The main control circuit 220 controls the second output terminal OUT2 to output a sensor power control signal. The second output terminal OUT2 of the main control circuit 220 is connected to the input terminal of the sensor power control circuit 240 to receive the high-level sensor power control signal output by the second output terminal OUT2. Because the lighting module 300 and the sensor module 100 are connected in parallel to the output terminal of the sensor power control circuit 240, the sensor power control circuit 240 outputs a power supply signal to the sensor module 100 in response to the sensor power control signal to power the sensor module 100 and ensure normal operation of the sensor module 100.

[0056] It should be noted that the intelligent induction lamp of the present invention connects the induction detection circuit 210, the main control circuit 220, the lighting power control circuit 230, and the sensor power control circuit 240 in parallel, that is, the lighting module 300 and the sensor module 100 are connected in parallel to the output of the control module 200, so that multiple control circuits can be connected and used at the same time, realizing signal intercommunication and increasing the flexibility of the use of the present invention.

[0057] It is worth noting that: Figure 2 Display: The sensor power control circuit 240 is connected between the output end of the lighting power control circuit 230 and the sensing detection circuit 210; according to another embodiment of the present invention, the lighting power control circuit 230 can also be connected between the output end of the sensor power control circuit 240 and the sensing detection circuit 210.

[0058] It should be noted that, in the case where the second electronically controlled element is a transistor, that is, the first port of the second electronically controlled element is the base, the second port of the second electronically controlled element is the collector, and the third port of the second electronically controlled element is the emitter, the connection relationship is as follows: the sensor power control circuit 240 includes an eighth resistor R8, a sixth transistor Q6, a fourth resistor R4, a second electronically controlled element Q2, and a second diode D2. One end of the eighth resistor R8 is connected to the second output terminal OUT2 of the main control circuit 220, and the other end of the eighth resistor R8 is connected to the base of the sixth transistor Q6. The sixth transistor Q The emitter of the sixth transistor Q6 is grounded. The collector of the sixth transistor Q6 is connected to one end of the fourth resistor R4. The other end of the fourth resistor R4 is connected to the base of the second electronically-controlled element Q2. The emitter of the second electronically-controlled element Q2 is connected to the sensor power supply. The collector of the second electronically-controlled element Q2 is connected to the anode of the second diode D2. The lighting module 300 and the sensor module 100 are connected in parallel to the cathode of the second diode D2. One end of the eighth resistor R8 is the input end of the sensor power supply control circuit 240, and the cathode of the second diode D2 is the output end of the sensor power supply control circuit 240.

[0059] According to one embodiment of the present invention, when the sensor module 100 does not sense a person, the induction detection circuit 210 outputs a high-level induction detection signal to the first input terminal IN of the main control circuit 220. The main control circuit 220 causes the second output terminal OUT2 to output a high-level sensor power control signal based on the high-level induction detection signal. The second electronic control element Q2 of the sensor power control circuit 240 is turned on in response to the sensor power control signal, allowing the sensor power supply to output a 5V voltage to the sensor module 100, that is, output a power supply signal. At this time, the voltage in the circuit is 5V. The sensor module 100 receives the power supply signal to achieve power supply, so that the sensor PIR can operate normally.

[0060] It should be noted that the first and second electronically controlled elements Q1 and Q2 can control the lighting module 300 and sensor module 100 by turning them on and off. When the sensor module 100 is performing sensing detection, the first and second electronically controlled elements Q1 and Q2 can be turned off, causing the sensing power control circuit 240 and the lighting power control circuit 230 to be in an off state. Only the sensing signal output by the sensor PIR is transmitted on the circuit. In this case, the signal received by the sensing detection circuit 210 is the actual sensing signal. It should be understood that the "first and second electronically controlled elements Q1 and Q2" described in the present invention do not specifically limit the types of the first and second electronically controlled elements Q1 and Q2. The first and second electronically controlled elements Q1 and Q2 can be transistors, MOSFETs, thyristors, relays, or other electrically controllable components, as long as they can control the normal operation of the smart sensor lamp of the present invention.

[0061] Reference Figure 7 , Figure 7 It is a specific circuit diagram of the lighting power supply and the sensor power supply of the intelligent induction lamp of an embodiment of the present invention. It can be understood that the step-down circuit includes the lighting power supply and the sensor power supply, and also includes an eleventh capacitor C11, a twelfth capacitor C12, a second controller U2, a tenth capacitor C10 and a ninth capacitor C9, wherein one end of the eleventh capacitor C11 is grounded, and the other end is connected to the lighting power supply, one end of the twelfth capacitor C12 is grounded, and the other end is connected to the lighting power supply, the input end of the second controller U2 is connected to the lighting power supply, the output end of the second controller U2 is connected to the sensor power supply, the ground end of the second controller U2 is grounded, one end of the tenth capacitor C10 is grounded, and the other end is connected to the sensor power supply, and one end of the ninth capacitor C9 is grounded, and the other end is connected to the sensor power supply.

[0062] It should be noted that the sensing detection circuit 210 includes a first resistor R1, a fifth resistor R5, and a third transistor Q3. One end of the first resistor R1 is connected to the first output terminal OUT, and the other end of the first resistor R1 is grounded through the fifth resistor R5. The base of the third transistor Q3 is connected between the first resistor R1 and the fifth resistor R5, the emitter of the third transistor Q3 is grounded, and the collector of the third transistor Q3 is connected to the first input terminal IN of the main control circuit 220. Among them, one end of the first resistor R1 is the input terminal of the sensing detection circuit 210, and the collector of the third transistor Q3 is the output terminal of the sensing detection circuit 210.

[0063] According to one embodiment of the present invention, when the sensor module 100 senses a person, it outputs a high-level sensing signal to the sensing detection circuit 210. At this time, the voltage on the line is 5V, causing the third transistor Q3 of the sensing detection circuit 210 to turn on and output a low-level sensing detection signal to the first input terminal IN of the main control circuit 220. When the sensor module 100 does not sense a person, it outputs a low-level sensing signal to the sensing detection circuit 210. At this time, the voltage on the line is 0V, causing the third transistor Q3 of the sensing detection circuit 210 to turn off and output a high-level sensing detection signal to the first input terminal IN of the main control circuit 220. Specifically, when the main control circuit 220 receives the low-level sensing detection signal, it controls the first output terminal OUT to output a high-level signal to the lighting power control module 230, causing the lighting module 300 to perform a power-on operation. When the main control circuit 220 receives the high-level sensing detection signal, it controls the second output terminal OUT2 to output a high-level signal to the sensor power control module 240, causing the sensor module 100 to be powered.

[0064] It should be noted that the sensor module 100 includes a sensor PIR, a fourth transistor Q4 and a first capacitor C1. The first port of the sensor PIR is connected to the positive electrode of the first capacitor C1, the second port PIR-OUT of the sensor PIR is connected to the base of the fourth transistor Q4, the third port of the sensor PIR is grounded, the emitter of the fourth transistor Q4 is connected to one end of the control module 200, the collector of the fourth transistor Q4 is connected to the positive electrode of the first capacitor C1, the negative electrode of the first capacitor C1 is grounded, the sensor PIR is used to obtain and output the sensing signal, and the first capacitor C1 is used to power the sensor PIR.

[0065] According to one embodiment of the present invention, when the sensor PIR in the sensor module 100 senses a person, the second port PIR-OUT of the sensor PIR outputs a high-level sensing signal, causing the fourth transistor Q4 connected to the second port PIR-OUT to be turned on and output the sensing signal to the sensing detection circuit 210. It should be noted that the voltage on the line is 5V at this time. When the sensor PIR in the sensor module 100 does not sense a person, the second port PIR-OUT of the sensor PIR outputs a low-level sensing signal, causing the fourth transistor Q4 connected to the second port PIR-OUT to be turned off and output the sensing signal to the sensing detection circuit 210. It should be noted that the voltage on the line is 0V at this time.

[0066] It should be noted that when the sensor module 100 is performing sensing detection, the first output terminal OUT and the second output terminal OUT2 respectively output a low-level lighting power control signal and a low-level sensor power control signal. Furthermore, the first electronically controlled element Q1 and the fifth transistor Q5, as well as the second electronically controlled element Q2 and the sixth transistor Q6, are turned off, thereby turning off the lighting power control circuit 230 and the sensor power control circuit 240. At this time, the first capacitor C1 connected to the sensor PIR is used to power the sensor module 100. The first capacitor C1 can be a supercapacitor or a battery, and the smart sensor lamp of the present invention is not particularly limited to this type of capacitor; it only needs to be able to maintain power to the sensor module 100.

[0067] It should be noted that, referring to Figure 4The sensor module 100 further includes a third diode D3, a third resistor R3, a third controller U3, and a second capacitor C2. The anode of the third diode D3 is connected to one end of the control module 200, the cathode of the third diode D3 is connected to the input of the third controller U3, the anode of the first capacitor C1 is connected to the input of the third controller U3, one end of the third resistor R3 is connected to the second port PIR-OUT of the sensor PIR, the other end of the third resistor R3 is connected to the input of the third controller U3, the ground terminal of the third controller U3 is grounded, the output of the third controller U3 is connected to the first port of the sensor PIR, one end of the second capacitor C2 is connected to the first port of the sensor PIR, and the other end of the second capacitor C2 is grounded. It is understood that when the voltage on the sensor module 100 is 0V, the third diode D3 is reversely blocked, preventing the voltage on the first capacitor C1 from being transmitted to the control module 200 and the lighting module 300.

[0068] It should be noted that the lighting module 300 includes a second resistor R2 and several light-emitting diodes connected in series. One end of the second resistor R2 is connected to one end of the control module 200, and the other end of the second resistor R2 is grounded through several light-emitting diodes connected in series. The light-emitting diodes are used to receive control signals and perform a turn-on operation according to the control signals.

[0069] Reference Figure 6 , Figure 6 This is a specific circuit diagram of the lighting module 300 of the smart sensor lamp according to an embodiment of the present invention. The lighting module 300 includes a second resistor R2, a fifth light-emitting diode D5, a first light-emitting diode D1 and a fourth light-emitting diode D4. One end of the second resistor R2 is connected to the output end of the lighting power control circuit 230, and the other end of the second resistor R2 is connected to the positive electrode of the fifth light-emitting diode D5. The cathode of the fifth light-emitting diode D5 is connected to the positive electrode of the first light-emitting diode D1, the cathode of the first light-emitting diode D1 is connected to the positive electrode of the fourth light-emitting diode D4, and the cathode of the fourth light-emitting diode D4 is grounded. The fifth light-emitting diode D5, the first light-emitting diode D1 and the fourth light-emitting diode D4 are used to receive the control signal sent by the lighting power control circuit 230 and perform a start operation according to the control signal.

[0070] It is understandable that the present invention does not specifically limit the type of the lighting module 300. For example, the lighting module 300 may be an LED lamp group or other types of lamps, as long as the lighting module 300 of the present invention can achieve lighting.

[0071] It should be noted that the voltage of the lighting power supply is greater than the voltage of the sensor power supply. In one embodiment of the present invention, the voltage of the lighting power supply is 12V, and the voltage of the sensor power supply is 5V. When the second electric control element Q2 is turned on, the sensor power supply outputs a voltage of 5V. At this time, the voltage on the output line is 5V. At this time, the voltage of the lighting module 300 is insufficient, and the start operation is not performed. The sensor module 100 continues to work. It can be understood that the "voltage of the lighting power supply is 12V, and the voltage of the sensor power supply is 5V" described in the present invention is only to better illustrate the working process of the smart sensor lamp of the present invention, and does not constitute a limitation on the voltage of the lighting power supply and the voltage of the sensor power supply. In actual work, the voltage of the lighting power supply and the voltage of the sensor power supply can be adjusted according to actual conditions.

[0072] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the scope of the present invention.
