[0033] Please see Figure 1 and Figure 2 This invention provides a light strip 10, including: a light strip body 100; a conductive module 101, wherein the conductive module 101 has a cavity 1011 inside and at least one conductive terminal 1012 is provided on the outside of the conductive module 101;

[0034] A power adjustment module 102 is disposed within the cavity 1011. The power adjustment module 102 includes a power adjustment switch 1021 and a power cord 103 connected to one side of the cavity 1011, and the LED strip body 100 connected to the other side of the cavity 1011. The conductive terminals 1012 are electrically connected to the LED strip body 100 and the power cord 103, respectively. The power adjustment module 102 adjusts the power of the LED strip body 100 through the power adjustment switch 1021.

[0035] In this embodiment, by integrating the power adjustment module 102 within the cavity 1011 of the conductive module 101, the complexity of external connections is reduced, and additional space is avoided in the LED strip body 100, making the overall structure of the LED strip 10 more compact. Furthermore, the cavity 1011 provides physical protection for the power adjustment module 102, reducing the impact of external shocks or dust on the components and improving product reliability. Additionally, users can achieve power adjustment through simple switching operations, eliminating the need for complex wiring 1031 or external device operation, thus improving product usability.

[0036] Furthermore, the conductive terminal 1012 includes an insertion end, which is inserted into the conductive module 101 and can be forcefully inserted into the cavity 1011. The insertion end is a copper block with a piercing head. In this embodiment, by pressing the conductive terminal 1012, the insertion end is forcefully inserted into the cavity 1011, which eliminates the need for additional fixing tools during installation, improving installation convenience. During installation, the power cord 103 is first connected to one side of the cavity 1011, and then the light strip body 100 is connected to the other side of the cavity 1011. Next, the insertion end is pressed, and the piercing head directly connects the power cord 103 and the light strip body 100. With the help of the power adjustment module 102, flicker-free lighting of the light strip 10 is achieved, improving conductivity efficiency.

[0037] It should be noted that the insertion end is a copper block with a pierced head, ensuring good electrical contact. Using a copper block as the material for the insertion end utilizes copper's excellent electrical and thermal conductivity, which helps to improve the conductivity of the conductive terminal 1012, while also enhancing heat dissipation and preventing performance degradation at high temperatures.

[0038] In this embodiment, the insertion end of the conductive terminal 1012 is a copper block with a piercing head, and the other end of the conductive terminal 1012 is an insulating material, which is the end that directly contacts the user when pressing the conductive terminal 1012. This prevents the user from getting an electric shock during installation or use. Furthermore, while designing the other end of the conductive terminal 1012 as an insulating material, anti-slip textures can be provided on the surface of the insulating material to increase finger friction and improve the success rate of pressing and installing.

[0039] Furthermore, the conductive terminal 1012 is detachably connected to the conductive module 101. In this embodiment, when the piercing head of the conductive terminal 1012 wears due to long-term insertion and removal, the conductive terminal 1012 can be replaced individually. The detachable design allows users or maintenance personnel to quickly replace the damaged conductive terminal 1012 without replacing the entire light strip 10 or conductive module 101. This not only reduces maintenance costs and time but also improves the maintainability of the product.

[0040] Furthermore, such as Figure 3 As shown, at least two insertion holes 10111 are provided in the cavity 1011, and at least two wires 1031 extend from the end of the power cord 103. The two wires 1031 are respectively inserted into the corresponding insertion holes 10111. At least two conductive terminals 1012 are provided, each corresponding to at least two insertion holes 10111.

[0041] In this embodiment, at least two wiring positions 1031 for power cords 103 are provided in the cavity 1011. At least two wirings 1031 extend from the end of the power cord 103, ensuring that each wiring 1031 is accurately inserted into the corresponding plug hole 10111 and can be fixed, avoiding wiring 1031 confusion or incorrect connection, and improving the accuracy and safety of installation.

[0042] In summary, by providing multiple insertion holes 10111 and corresponding conductive terminals 1012, the connection of the power cord 103 is more flexible, accommodating power cords of different specifications and quantities, thus improving the product's versatility and adaptability. The design of multiple wiring connections 1031 and corresponding conductive terminals 1012 ensures stable power transmission, avoiding electrical faults caused by wiring issues, and improving product reliability and safety. A stable power connection provides reliable power support for the power adjustment module 102, ensuring the accuracy and stability of the power adjustment function and meeting the user's needs for power adjustment of the LED strip 10.

[0043] Furthermore, such as Figure 4 and Figure 5 The diagram shown is a circuit schematic of the power regulation module 102. The power regulation module 102 also includes a diode, a first transistor, and a microcontroller 1022; one end of the diode is connected to one end of the first transistor, and the other end of the first transistor is connected to one end of the microcontroller 1022.

[0044] In this embodiment, the positive input terminal of the circuit is connected to the anode of diode D1 (1N4148), its cathode is connected to the base of the first transistor Q1 (2N3904), the collector of the first transistor Q1 is connected to the Vin pin of the microcontroller 1022, the Gnd pin is connected to ground, and the negative input terminal of the circuit is connected to the ground line of the power supply.

[0045] In summary, diode D1 (1N4148) is used to protect circuit 1024 from reverse power connection. The reverse connection protection function of diode D1 can prevent circuit damage caused by reverse power connection, improving product reliability. Secondly, the first transistor Q1 can act as a switch or amplifier to control the power input to the Vin pin of microcontroller 1022, thereby realizing power regulation or power management functions. Furthermore, the Vin pin of microcontroller 1022 is used to receive the power input, and the Gnd pin is grounded, forming a complete circuit loop.

[0046] Furthermore, the power regulation module 102 also includes a second transistor, a connector, a MOSFET 1023, and a protection circuit 1024; one end of the second transistor is connected to one end of the connector, the connector is connected to one end of the MOSFET 1023, and the other end of the MOSFET 1023 is connected to the protection circuit 1024.

[0047] In this embodiment, connector J1 is a 4-pin connector, and MOSFET 1023 is a module containing multiple MOSFETs. Its gate (G) is connected to one end of the push-button switch key, its source (S) is connected to VDD, and its drain (D) is connected to protection circuit 1024. Pin 1 of connector J1 is connected to ground, pin 2 is connected to pin 6 of MOSFET 1023, pin 3 is connected to pin 7 of MOSFET 1023, and pin 4 is connected to pin 8 of MOSFET 1023. The collector of the second transistor Q2 is connected to pin 1 of connector J1 and pin 2 of MOSFET 1023, and pin 5 of MOSFET 1023 is connected to protection circuit 1024. Protection circuit 1024 is used to prevent overload, short circuit, and other abnormal conditions from occurring during power adjustment of the LED strip 10, thereby improving the safety and reliability of the LED strip 10.

[0048] In a specific embodiment, a PWM (Pulse Width Modulation) signal is sent by the microcontroller 1022 to the MOSFET 1023 via the power adjustment switch 1021. The MOSFET 1023 then adjusts its switching frequency (duty cycle) based on the received PWM signal. A higher PWM signal frequency results in a larger duty cycle and a longer conduction time for the MOSFET 1023, thus increasing the power of the LED strip 10. Conversely, a lower PWM signal frequency results in a smaller duty cycle and a shorter conduction time for the MOSFET 1023, leading to lower power for the LED strip 10. This adjustment method allows for multi-level brightness adjustment of the LED strip 10, meeting the lighting needs of different scenarios.

[0049] Furthermore, the power adjustment switch 1021 is provided with multiple power levels. In this embodiment, the power adjustment switch 1021 is a multi-power switch, including at least a low power level, a medium power level, and a high power level. The user can achieve step-by-step adjustment of the power of the LED strip 10 by switching between power levels. Specifically, the power levels of the power adjustment switch 1021 correspond one-to-one with the duty cycle of the PWM signal, and each power level triggers the microcontroller 1022 to output a fixed PWM duty cycle signal. For example, the power adjustment switch 1021 has 3 to 5 power levels, corresponding to an adjustment range of 20% to 100% of the rated power of the LED strip 10.

[0050] In addition, a limit structure can be installed on the power adjustment switch 1021 to prevent users from accidentally skipping the intermediate power level. A symbol or LED indicator can also be installed next to the power adjustment switch 1021 to display the current power level status.

[0051] Furthermore, the light strip body 100 includes a flexible circuit board 1001 and a plurality of LED light sources 1002 disposed on the flexible circuit board 1001. In this embodiment, the flexible circuit board 1001 (FPC) has good flexibility and bendability, making it suitable for manufacturing light strips 10 of various shapes, while the plurality of LED light sources 1002 provide a uniform lighting effect. This design allows the light strip 10 to adapt to different installation environments, such as curved walls, furniture contours, etc.

[0052] Furthermore, such as Figure 6 As shown, the conductive module 101 is provided with a clearance position 1013, and the power adjustment switch 1021 is located on the clearance position 1013. In this embodiment, the clearance position 1013 in the conductive module 101 provides installation space for the power adjustment switch 1021, allowing the power adjustment switch 1021 to be embedded in the conductive module 101, making the switch and the conductive module 101 form a whole. This facilitates user operation, allowing users to easily perform power adjustment without needing to find or connect external control devices, thus improving the user experience. It also prevents the switch from being accidentally touched or damaged during use, improving the reliability and safety of the product.

[0053] Specifically, the power adjustment switch 1021 is a toggle switch. In this embodiment, the toggle switch has the advantages of simple mechanical structure, intuitive operation, and low cost. By placing the toggle switch in the clearance position 1013, the switch and the conductive module 101 form an integral unit. Users can adjust the power of the light strip 10 with a simple toggle action, eliminating the need for complicated operation procedures, reducing the difficulty of use, and improving the user experience.
