Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] Please refer to Figures 1-4 The present invention provides a rechargeable LED lighting device, including a lighting circuit, which includes a power supply module, a circuit charge and discharge protection module, a voltage regulator module and a switch control module.

[0028] One end of the circuit charging and discharging protection module is connected to the voltage regulator module and the power supply module respectively, and the other end of the voltage regulator module is connected to the switch lighting module.

[0029] The switch control module is connected to several groups of lighting modules.

[0030] The structure of this invention mainly includes a power supply module, a circuit charge / discharge protection module, a voltage regulator module, and a switch control module. One end of the circuit charge / discharge protection module is connected to both the voltage regulator module and the power supply module, and the other end of the voltage regulator module is connected to the switch lighting module. The switch control module is connected to several groups of lighting modules. This structure simplifies the required components compared to existing technologies while achieving both lighting and charging of the lamp 2. It also simplifies the overall circuit structure, reduces the required area, and consequently reduces the overall size of the device, making it more portable.

[0031] In one exemplary embodiment of this utility model, the road charging and discharging protection module includes a first resistor R1, a second resistor R2, a first indicator light 8, a second indicator light 9, a first processor U1, a first capacitor C1, and a second capacitor C2.

[0032] The first resistor R1 is connected to one end of the first indicator light 8 and the second indicator light 9 respectively, and the other end of the first indicator light 8 and the second indicator light 9 is connected to the first processor U1 respectively.

[0033] The first capacitor C1, the second capacitor C2, and the second resistor R2 are respectively connected to the first processor U1, and the end of the second capacitor C2 connected to the first processor U1 is also connected to the power module.

[0034] The first indicator light 8 and the second indicator light 9 are used to indicate the current charging status, such as charging in progress or charging completed. They are distinguished by two different colored lights. The first processor U1 is a PL5057 chip, which has battery reverse connection protection and linear charging management functions. The charging circuit can accept a 5V charging input from USB.

[0035] Specifically, the first indicator light 8 and the second indicator light 9 are connected to interfaces 1 and 5 of the first processor U1, respectively, interface 2 is grounded, and the first capacitor C1, the second capacitor C2, and the second resistor R2 are connected to interfaces 4, 3, and 6, respectively.

[0036] In one exemplary embodiment of this utility model, the voltage regulator module includes a third capacitor C3, a fourth capacitor C4, and a second processor U2. One end of the third capacitor C3 is connected to the circuit charge and discharge protection module, the power supply module, and the second processor U2, respectively. One end of the fourth capacitor C4 is connected to the switch control module and the second processor U2, respectively. The second processor U2 is a 662K voltage regulator.

[0037] In this module, the inductor design has been eliminated, further simplifying the circuit structure.

[0038] In one exemplary embodiment of this utility model, the switch control module includes a third processor U3 and a push-button switch 11. The third processor U3 is connected to the lighting module and the push-button switch 11 respectively. The push-button switch 11 is used to input external control signals to the third processor U3. The third processor U3 is a 9BF3E packaged in an SOP8 package.

[0039] Specifically, the lighting module includes a third resistor R3 and a lighting lamp 2. One end of the third resistor R3 is connected to the third processor U3, and the other end is connected to the lighting lamp 2. The lighting module is equipped with three sets.

[0040] When in use, it does not work when powered on. After pressing button switch 11, L1 lights up. After pressing it again, L2 lights up. After pressing it again, both L1 and L2 light up. After pressing it again, L3 lights up. After pressing it again, all lights off.

[0041] This utility model also provides a rechargeable LED lighting device, which includes a housing and a circuit board 7. The circuit board 7 is detachably disposed in the housing and is used to set the above-mentioned rechargeable LED lighting circuit.

The bottom of the cylindrical body 5 is provided with a charging port 6, which is connected to the power module.

[0043] In the existing technology, since the lamp holder 3 is not fixed in a more comprehensive way, it is generally fixed by a threaded connection and compression. On the one hand, if it is not connected in place, it is easy to cause shaking inside. On the other hand, when the threaded connection rotates, it will drive the lamp holder 3 to rotate, which may cause the connection wire between the lighting lamp 2 and the circuit board 7 to fall off.

[0044] Therefore, in this embodiment, the lamp source fixing device includes a lamp holder 3, a positioning protrusion 4 and a cap 1. Several lighting lamps 2 are set in the lamp holder 3. Several through holes that are adapted to the positioning protrusion 4 are set around the edge of the lamp holder 3. The lamp holder 3 is positioned by the positioning protrusion 4 and the through holes. The cap 1 is threaded to the top of the cylinder 5.

[0045] The relative positioning of the lamp holder 3 is achieved by positioning protrusion 4 and the third pass, so that the lamp holder 3 cannot follow the rotation, thus reducing the failure rate.

[0046] Secondly, the cylinder 5 has several internally threaded posts 10 inside, and the circuit board 7 has several through holes. The circuit board 7 is detachably connected to the cylinder 5 by screws and internally threaded posts 10.
