[0030] The control circuit also includes a wireless receiver module, which is connected to the control module and is designed to receive wireless remote control commands. The wireless receiver module can be, for example, an infrared receiver or a Bluetooth receiver.

[0031] The working principle of the control circuit of the present invention is explained in more detail below.

[0032] When the charging socket 161 is connected to the external power source, the fourth driver chip U4 outputs a 5V_DET control signal via the AN1 / IO2 pin to the charging module 165, which is located between the eleventh resistor R11 and the fourteenth resistor R14. This causes the first charging chip U1 to charge the rechargeable battery 13. In this state, the first MOS transistor Q1 is in a high-level cutoff state, and the 5V voltage supplied by the external power source is reduced by the first diode D1 to obtain the initial operating voltage VCC, which is then output to the voltage converter module 164 and the control module 163. The first indicator lamp LED1 shows that the rechargeable battery 13 is charging, and the second indicator lamp LED2 shows that the rechargeable battery 13 is fully charged.The first indicator lamp LED1 can be a green LED, and the second indicator lamp LED2 can be a blue LED.

[0033] When the charging socket 161 is not connected to the external power source, the first MOS transistor Q1 is in a conducting state caused by a low level. In this state, the rechargeable battery 13 outputs the initial operating voltage VCC via the first MOS transistor Q1, thus providing the operating voltage for the voltage converter module 164 and the control module 163.

[0034] The model of the third charging protection chip U3 can be XB5358D, which ensures overcharge protection as well as deep discharge protection of the rechargeable battery 13, thus increasing the operational safety of the rechargeable battery 13 and extending its service life.

[0035] Furthermore, the fourth driver chip U4 outputs a PWM1 control signal to the fifth power control chip U5 via the PWM0 / IO0 pin. This allows the fifth power control chip U5 to convert the initial operating voltage VCC into the target operating voltage required for the first color lamp 151 and the second color lamp 152, thus driving them to emit light. The fourth driver chip U4 outputs a PWM2 control signal to the first control module 166 via the PWM2 / IO1 pin. The brightness of the first color lamp 151 can be controlled by adjusting the duty cycle of the PWM2 control signal. The fourth driver chip U4 outputs a PWM3 control signal to the second control module 167 via the IO13 / PWM1 pin. The brightness of the second color lamp 152 can be controlled by adjusting the duty cycle of the PWM3 control signal.When the PWM2 control signal remains permanently low, the sixth MOS transistor Q6 is in the off state, and the first color lamp 151 is off. When the PWM3 control signal remains permanently low, the seventh MOS transistor Q7 is in the off state, and the second color lamp 152 is off. Therefore, when the first color lamp 151 is illuminated, the second color lamp 152 can be switched off by the PWM3 control signal. When the second color lamp 152 is illuminated, the first color lamp 151 can be switched off by the PWM2 control signal, thus enabling switching between the first color lamp 151 and the second color lamp 152.

[0036] In one embodiment, the switching command can be entered via the mechanical push button 162, and the fourth driver chip U4 can, upon receiving the switching command, switch between the first color lamp 151 and the second color lamp 152, as well as control the brightness of the first color lamp 151 and the second color lamp 152. It is assumed that each color lamp has two brightness levels. Upon the first pressing of the mechanical push button 162, the first color lamp 151 is switched on by default. In this state, the brightness of the first color lamp 151 is at the first level, and the second color lamp 152 is switched off. After pressing the mechanical push button 162 twice, the switching command causes the brightness of the first color lamp 151 to be adjusted to the second level.This means that after the second press of the mechanical push button 162, the first color lamp 151 remains illuminated, and its brightness is adjusted from the first to the second level. After the third press of the mechanical push button 162, the second color lamp 152 illuminates, and the first color lamp 151 is switched off. In this state, the brightness of the second color lamp 152 is at the first level. After the fourth press of the mechanical push button 162, the brightness of the second color lamp 152 is adjusted to the second level, while the first color lamp 151 remains off. After the fifth press of the mechanical push button 162, both the second color lamp 152 and the first color lamp 151 are switched off. After the sixth press of the mechanical push button 162, the state returns in which the first color lamp 151 is on and the second color lamp 152 is off.This cycle repeats itself; that is, the mechanical push button 162 switches between different colored lamps and adjusts their brightness after every five presses. In this way, the function of switching between colored lamps and adjusting the brightness can be achieved using a single push button, thus enabling color and brightness adjustment.

[0037] In other embodiments, switching commands can also be entered via the touch button 168, the operating principle of which corresponds to that of the mechanical push button 162 and is therefore not described in further detail here.

[0038] In one embodiment, the switching command can also be entered via a wireless remote control to switch between color lamps and adjust the brightness. The wireless receiver module wirelessly receives the remote control signal from a wireless remote, and the fourth driver chip, U4, switches between color lamps and adjusts the brightness based on the received remote control signal. The wireless remote control can be equipped, for example, with a button for the first color lamp, a button for the second color lamp, a button for the first brightness level, a button for the second brightness level, and so on, with different buttons generating corresponding remote control signals to enable brightness and color adjustment. As shown in Fig.As shown in Figure 10, the control circuit can further include a wireless receiver module 172, which comprises a sixth receiver chip U6 and its peripheral circuitry. A fourth and a fifth pin of the sixth receiver chip U6 are each connected to a ninth and an eighth pin of the fourth driver chip U4. The remote control signal is received wirelessly via the sixth receiver chip U6 and transmitted to the fourth driver chip U4 to enable switching between color lamps and brightness control.
