[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] This utility model embodiment provides a hand-scan sensor light 100, such as... Figure 1 The system includes a main control unit 110, a first connector 120, a second connector 130, a lamp module 140, a sensing unit 150, a first switch unit 160, and a second switch unit 170.

[0029] The first connector 120 is used to input the power supply voltage. The first connector 120 can be connected to the power supply interface 201 of the external power supply 200, or to the second connector 130 of another hand sweep sensor light 100 to obtain the power supply voltage and provide the working voltage for the entire hand sweep sensor light 100.

[0030] The second connector 130 is connected to the first connector 120, and the second connector 130 can also be connected to the first connector 120 of another hand-swipe sensor light 100. The second connector 130 serves as an interface for connecting another hand-swipe sensor light 100, allowing the hand-swipe sensor light 100 to be connected in series with another hand-swipe sensor light 100.

[0031] The lamp module 140 is connected to the first connector 120 and can obtain power supply voltage from the first connector 120.

[0032] The first switch unit 160 is disposed between the lamp module 140 and the ground terminal. When the first switch unit 160 is open, the path between the lamp module 140 and the ground terminal is broken, and the lamp module 140 is not lit; when the first switch unit 160 is closed, the path between the lamp module 140 and the ground terminal is closed, and the lamp module 140 is lit.

[0033] The second switch unit 170 is disposed between the second connector 130 and the ground terminal. When the second switch unit 170 is open, the path between the second connector 130 and the ground terminal is broken, the power supply circuit of the second connector 130 is disconnected, and the second connector 130 cannot obtain the power supply voltage. When the second switch unit 170 is closed, the path between the second connector 130 and the ground terminal is closed, the power supply circuit of the second connector 130 is closed, and the power supply voltage is obtained. The other hand-sweeping sensor light 100 connected to it can obtain the power supply voltage and operate normally.

[0034] The main control unit 110 is connected to the first connector 120, the sensing unit 150, the driving end of the first switching unit 160 and the driving end of the second switching unit 170. The main control unit 110 is used to receive the sensing signal from the sensing unit 150 and output a PWM signal to drive the first switching unit 160 and the second switching unit 170 to work, so as to control the operation of the lamp module 140 and connect or disconnect the path between the second connector 130 and the ground terminal.

[0035] This application includes a main control unit 110, a first connector 120, a second connector 130, a lamp module 140, a sensing unit 150, a first switch unit 160, and a second switch unit 170. The first connector 120 is used to input the power supply voltage, providing the operating voltage for the entire hand-sweeping sensor lamp 100. The first switch unit 160 is located between the lamp module 140 and the ground terminal, and the second switch unit 170 is located between the second connector 130 and the ground terminal. After receiving the sensing signal from the sensing unit 150, the main control unit 110 outputs a PWM signal to drive the first switch unit 160 and the second switch unit 170 to work, thereby controlling the operation of the lamp module 140 and connecting or disconnecting the path between the second connector 130 and the ground terminal. Connector 120 is connected, and the second connector 130 can be connected to the first connector 120 of another hand-swipe sensor light 100 to achieve connection with another hand-swipe sensor light 100. Therefore, the hand-swipe sensor lights 100 of this application can be used in series, in parallel, or in a mixed manner through the connection of the first connector 120 and the second connector 130. Each hand-swipe sensor light 100 after connection can sense and control the switch of its own light module 140, and can also control the switch of the other hand-swipe sensor light 100 connected in series. This improves the assembly flexibility of the hand-swipe sensor light 100, increases the fun of user self-assembly, enhances the user experience, and manufacturers only need to produce one product, making production simple and convenient, reducing material inventory, and saving costs.

[0036] The first connector 120 and the second connector 130 can both be USB females. When they need to be used in series, a USB male cable can be used to connect the second connector 130 of one hand-sweep sensor 100 to the first connector 120 of another hand-sweep sensor 100. When they need to be used in parallel, a JST-USB male cable can be used to connect the first end of each hand-sweep sensor 100 to the external power supply 200.

[0037] The main control unit 110 can use the existing microcontroller U1 to receive the sensing signal from the sensing unit 150 and output a PWM signal to drive the first switching unit 160 and the second switching unit 170 to work.

[0038] The light module 140 can be a light panel or a light strip, and designers can set it according to their needs.

[0039] refer to Figure 1 and Figure 2In an optional embodiment of this application, the main control unit 110 is provided with a first output pin B_PWM / EL, and the second switching unit 170 includes a second switching transistor Q2, a first resistor R1 and a second resistor R2. The gate of the second switching transistor Q2 is connected to the first output pin B_PWM / EL through the first resistor R1, the source is grounded, and the drain is connected to the second connector 130. One end of the second resistor R2 is connected to the gate of the second switching transistor Q2, and the other end is grounded.

[0040] By configuring the second switch Q2, it can be turned off or on under the drive of the PWM signal output from the first output pin B_PWM / EL of the main control unit 110, thereby connecting or disconnecting the path between the second connector 130 and the ground terminal, that is, connecting or disconnecting the power supply circuit of the second connector 130, thus realizing the sensor switch function of the hand-swipe sensor 100 connected to the other hand-swipe sensor 100. The first resistor R1 is the driving resistor of the second switch Q2, which acts as a current limiting buffer to prevent the second switch Q2 from being damaged by excessive current. The second resistor R2 is the pull-down resistor of the second switch Q2 to prevent the second switch Q2 from being mistakenly turned on when there is no driving signal.

[0041] In practice, the second switch Q2 is an NMOS transistor. NMOS transistors have a fast response speed and high switching speed, and can be turned on by only applying a positive voltage to the gate, making the driving circuit relatively simple.

[0042] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the main control unit 110 is provided with a second output pin CLK and a read input pin RDIN. The sensing unit 150 includes an infrared sensor 151, a third resistor R3, a fourth resistor R4, a fifth resistor R5, and a transistor Q1. The infrared sensor 151 has an built-in infrared emitting tube D1 and a photosensitive receiving tube D2. The positive terminal of the infrared emitting tube D1 is connected to the first connector 120. The third resistor R3 is connected in series between the negative terminal of the infrared emitting tube D1 and the collector of the transistor Q1. The fourth resistor R4 is connected in series between the base of the transistor Q1 and the second output pin CLK of the main control chip. The emitter of the transistor Q1 is grounded. The negative terminal of the photosensitive receiving tube D2 is connected to the first connector 120. The positive terminal of the photosensitive receiving tube D2 is connected to the read input pin RDIN and one end of the fifth resistor R5. The other end of the fifth resistor R5 is grounded.

[0043] The infrared sensor 151 is a sensor that uses infrared light for data processing. Using the infrared sensor 151 as the sensing control method for the hand-sweeping sensor light 100 allows the light to be switched on and off simply by sensing the infrared signal, avoiding the need for physical contact or pressing a switch, thus providing users with a convenient switching experience. The infrared sensor 151 integrates an infrared emitting diode D1 and a photosensitive receiving diode D2. The same device can perform both infrared emission and reception functions, simplifying design and installation. The infrared emitting diode D1 is composed of infrared light-emitting diodes D3 forming a light-emitting element. A PN junction is made of a material with high infrared emissivity. A forward bias voltage injects current into the PN junction to excite infrared light, with a spectral power distribution of a center wavelength of 830-950nm. The photosensitive receiving diode D2 is a PN junction with photosensitive characteristics, belonging to the photosensitive diode D3. It has unidirectional conductivity, therefore a reverse voltage is required for operation. In the absence of light, there is a very small reverse saturation leakage current, at which point the photosensitive diode does not conduct. When there is light, the saturated reverse leakage current immediately increases, forming a photocurrent, which increases with the intensity of incident light within a certain range.

[0044] In operation, the second output pin CLK of the main control unit 110 outputs a PWM signal, which, after current limiting by the fourth resistor R4, drives the transistor Q1 to continuously turn on and off. When the second output pin CLK of the main control unit 110 outputs a high level, the transistor Q1 is turned on, and the power supply voltage input to the first connector 120 passes through the infrared emitting diode D1 and the third resistor R3 to ground, causing the infrared emitting diode D1 to emit infrared light. When the second output pin CLK of the main control unit 110 outputs a low level, the transistor Q1 is turned off, and the infrared emitting diode D1 stops emitting infrared light. When the photosensitive receiving diode D2 does not receive infrared light, it is in the off state, and the read input pin RDIN of the main control unit 110 remains at a low level. When a hand or other obstruction blocks the sensing head, the photosensitive receiving diode D2 receives the infrared light emitted by the infrared emitting diode D1 and reflected by the obstruction, and is turned on. The read input pin RDIN of the main control unit 110 will have a pulse waveform, which the main control unit 110 detects to switch on and off.

[0045] The use of a PWM signal to drive transistor Q1, which in turn drives infrared emitting diode D1, serves two purposes: firstly, it reduces standby power consumption, and secondly, it effectively prevents interference from other infrared rays.

[0046] refer to Figure 1 and Figure 2In an optional embodiment of this application, the main control unit 110 is provided with a third output pin N_PWM, and the first switching unit 160 includes a first switching transistor Q1, a sixth resistor R6 and a seventh resistor R7. The gate of the first switching transistor Q1 is connected to the third output pin N_PWM through the sixth resistor R6, the source is grounded, and the drain is connected to the lamp module 140. One end of the seventh resistor R7 is connected to the gate of the first switching transistor Q1, and the other end is grounded.

[0047] By setting the first switching transistor Q1, it can be turned off or on under the drive of the PWM signal output from the third output pin N_PWM of the main control unit 110, thereby connecting or disconnecting the path between the lamp module 140 and the ground terminal, that is, connecting or disconnecting the power supply circuit of the lamp module 140, thus realizing the switching of the lamp module 140. The sixth resistor R6 is the driving resistor of the first switching transistor Q1, connected in series between the third output pin N_PWM of the main control unit 110, and acts as a current limiting buffer. The seventh resistor R7 is the pull-down resistor of the first switching transistor Q1 to prevent the first switching transistor Q1 from being mistakenly turned on when there is no driving signal.

[0048] In practice, the first switch Q1 is an NMOS transistor. When a hand is waved in front of the infrared sensor 151, the third output pin N_PWM of the main control unit 110 outputs a gradually high-level signal, the first switch Q1 slowly turns on, and the lamp module 140 gradually brightens; when the hand is waved again in front of the infrared sensor 151, the third output pin N_PWM of the main control unit 110 outputs a gradually low-level signal, the first switch Q1 slowly turns off, and the lamp module 140 gradually dims.

[0049] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the hand-sweeping sensor light 100 further includes a voltage regulator unit 180. The voltage input terminal of the voltage regulator unit 180 is connected to the first connector 120, and the voltage output terminal is connected to the sensing unit 150, the main control unit 110, and the second connector 130.

[0050] The voltage regulator unit 180 can provide a constant output voltage, which will not be affected even if the input voltage fluctuates. It can provide a stable power supply voltage for the downstream circuit components, avoid damage to the components due to voltage fluctuations, and extend the overall service life of the hand-swipe sensor light 100.

[0051] refer to Figure 1 and Figure 2In an optional embodiment of this application, the voltage regulator unit 180 includes a three-terminal regulator U2, a first capacitor C1, a second capacitor C2, a third capacitor C3, and a fourth capacitor C4. The voltage input pin of the three-terminal regulator U2 is connected to the first connector 120, the voltage output pin is connected to the sensing unit 150, the main control unit 110, and the second connector 130, and the ground pin is connected to ground. The first capacitor C1 and the second capacitor C2 are connected in parallel. The first parallel node of the first capacitor C1 and the second capacitor C2 is connected to the voltage input terminal of the three-terminal regulator U2, and the second parallel node of the first capacitor C1 and the second capacitor C2 is grounded. The third capacitor C3 and the fourth capacitor C4 are connected in parallel. The first parallel node of the third capacitor C3 and the fourth capacitor C4 is connected to the voltage output terminal of the three-terminal regulator U2, and the second parallel node of the third capacitor C3 and the fourth capacitor C4 is grounded.

[0052] The three-terminal regulator U2 is a commonly used electronic component used to provide a stable output voltage. It is widely used in various electronic circuits to ensure that subsequent circuits can operate under a stable voltage. The three-terminal regulator U2 is simple and efficient in design, making it easy to achieve stable voltage output in electronic designs. It is also very easy to use, requiring only a few external components to achieve the voltage regulation function, and its circuit structure is simple.

[0053] The first capacitor C1 and the third capacitor C3 are used to filter out low-frequency interference, while the second capacitor C2 and the fourth capacitor C4 are used to filter out high-frequency ripple. Together with the three-terminal voltage regulator U2, they stabilize the power supply voltage input to the first connector 120 within a suitable range. Specifically, the 12V power supply voltage input to the first connector 120 is filtered by the first capacitor C1 and the second capacitor C2 before being input to the three-terminal voltage regulator U2. The voltage regulated by the three-terminal voltage regulator U2 is then filtered by the third capacitor C3 and the fourth capacitor C4, outputting a stable 5V to power the sensing unit 150, the main control unit 110, and the second connector 130.

[0054] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the hand-sweeping sensor light 100 further includes a reverse connection protection unit 190, which is disposed between the first connector 120 and the voltage input terminal of the voltage regulator unit 180.

[0055] By setting up the reverse connection protection unit 190, reverse current can be effectively prevented from flowing into the circuit, circuit faults caused by polarity errors can be prevented, the reliability and stability of the hand-swipe sensor light 100 can be improved, and the service life of the hand-swipe sensor light 100 can be extended.

[0056] Specifically, refer to Figure 1 and Figure 2In an optional embodiment of this application, the reverse connection protection unit 190 includes an eighth resistor R8 and a diode D3. One end of the eighth resistor R8 is connected to the first connector 120, and the other end is connected to the positive terminal of the diode D3. The negative terminal of the diode D3 is connected to the voltage input terminal of the voltage regulator unit 180.

[0057] The eighth resistor, R8, acts as a buffer and current limiter when the hand-swipe sensor light 100 is first powered on, protecting the voltage regulator unit 180. Diode D3 has unidirectional conductivity. When the positive terminal of the input power supply 200 is connected to the positive terminal of diode D3, diode D3 conducts, and the voltage regulator unit 180 and subsequent circuits are powered on and operate normally. When the input power supply 200 is reversed, diode D3 is cut off, and no current flows through the voltage regulator unit 180 and subsequent circuits, thus providing protection.

[0058] refer to Figure 1 and Figure 2 In an optional embodiment of this application, the hand-sweeping sensor light 100 further includes a long strip-shaped circuit board. The main control unit 110, the first connector 120, the second connector 130, the lamp module 140, the sensing unit 150, the first switch unit 160, and the second switch unit 170 are all disposed on the circuit board. Along the length of the circuit board, the first connector 120 and the second connector 130 are located at the beginning and end of the circuit board, respectively.

[0059] The first connector 120 and the second connector 130 are respectively located at the beginning and end of the circuit board, providing more flexibility for the layout and connection of multiple hand-swipe sensor lights 100. During installation, the number and position of the lights can be adjusted according to the actual space requirements, and the installation space can be effectively utilized, especially in space-constrained environments, such as inside cabinets or narrow corridors. When the system needs maintenance or troubleshooting, the connectors at the beginning and end make it easier to disassemble and replace individual hand-swipe sensor lights 100 without disassembling the entire system. Simply disconnect the connection at both ends of the faulty hand-swipe sensor light 100.

[0060] In an optional embodiment of this application, reference is made to Figure 2The main control unit 110 also has an enable pin EL1. The hand-sweep sensor light 100 also includes a ninth resistor R9 and a tenth resistor R10 connected in series. The series connection point of the ninth resistor R9 and the tenth resistor R10 is connected to the enable pin EL1 of the main control unit 110. The other end of the ninth resistor R9 is connected to the first connector 120, and the other end of the tenth resistor R10 is grounded. The ninth resistor R9 and the tenth resistor R10 are mode selection resistors. By adjusting the resistance values ​​of the ninth resistor R9 and the tenth resistor R10, various different operating modes can be combined. For example, segmented dimming and stepless dimming, the PWM frequency of the driving MOSFET, two-stage dimming or three-stage dimming, gradual effect or no gradual effect, minimum brightness, whether a delay is required to turn off the light, whether it is on or off upon power-on, etc. The software control of the specific operating mode can be implemented by existing reproducible programs, which are not improvements of this application and will not be described in detail here.

[0061] This application also provides a lighting system. (See reference...) Figure 3 and Figure 4 The lighting system includes a power supply 200 and multiple hand-swipe sensor lights 100 as described above. The power supply 200 is provided with multiple power supply interfaces 201. The first connectors 120 of the multiple hand-swipe sensor lights 100 are connected to the multiple power supply interfaces 201 in a one-to-one correspondence. Alternatively, the multiple hand-swipe sensor lights 100 can be connected in series or in a mixed configuration through the connection of the first connector 120 and the second connector 130. In the series configuration, the first connector 120 of the first hand-swipe sensor light 100 is connected to one of the power supply interfaces 201. In the mixed configuration, the first connector 120 of at least one hand-swipe sensor light 100 is connected to one power supply interface 201.

[0062] The hand-sweeping sensor light 100 in the lighting system of this application comprises a main control unit 110, a first connector 120, a second connector 130, a lamp module 140, a sensing unit 150, a first switch unit 160, and a second switch unit 170. The first connector 120 can be connected to the power supply interface 201 of the power supply 200 to input the power supply voltage and provide the operating voltage for the entire hand-sweeping sensor light 100. The first switch unit 160 is located between the lamp module 140 and the ground terminal, and the second switch unit 170 is located between the second connector 130 and the ground terminal. After receiving the sensing signal from the sensing unit 150, the main control unit 110 outputs a PWM signal to drive the first switch unit 160 and the second switch unit 170 to work, thereby controlling the operation of the lamp module 140 and connecting or disconnecting the second connector 130 from the ground terminal. The second connector 130 is connected to the first connector 120, and the second connector 130 can also be connected to the first connector 120 of another hand-sweep sensor light 100 to achieve connection with the other hand-sweep sensor light 100. Therefore, the hand-sweep sensor lights 100 of this application can be used in series, in parallel, or in a mixed manner through the connection of the first connector 120 and the second connector 130. Each hand-sweep sensor light 100 after connection can sense and control the switch of its own light module 140, and can also control the switch of the other hand-sweep sensor light 100 connected in series, improving the assembly flexibility of the hand-sweep sensor light 100, increasing the fun of user self-assembly, improving the user experience, and the manufacturer only needs to produce one product, which is simple and convenient to produce, reduces material inventory, and saves costs.

[0063] When multiple hand-scan sensor lights 100 are connected in series, the first connector 120 of the first hand-scan sensor light 100 is connected to one of the power supply interfaces 201, and the first connector 120 of the subsequent hand-scan sensor lights 100 is connected to the second connector 130 of the previous hand-scan sensor. Each hand-scan sensor light 100 can sense and control the switching of itself and the subsequent hand-scan sensor lights 100. A simplified structural diagram is shown below. Figure 3 As shown in the diagram. When multiple hand-swipe sensor lights 100 are connected in parallel, the first connector 120 of each hand-swipe sensor light 100 is connected to multiple power supply interfaces 201 one-to-one. Each hand-swipe sensor light 100 can obtain power supply voltage from the power supply 200 and can independently realize the function of sensor-activated light switching. A simplified structural diagram is shown in the diagram. Figure 4 As shown. When multiple hand-swipe sensor lights 100 are connected in a mixed configuration, the first connector 120 of one or more of the hand-swipe sensor lights 100 can be connected one-to-one with the power supply interface 201 of the power supply 200. Other hand-swipe sensor lights 100 can be connected in series after the already connected hand-swipe sensor lights 100, or connected in parallel after the already connected hand-swipe sensor lights 100, forming a mixed configuration.
