The working principle of the control circuit of the present disclosure will be further introduced below.

When the charging socket 161 is connected to the external power source, the fourth driving chip U4 outputs a 5V_DET control signal through the AN1/IO2 pin to the charging module 165 that is between the eleventh resistor R11 and the fourteenth resistor R14, so that the first charging chip U1 charges the rechargeable battery 13. At this time, the first MOS transistor Q1 is in a high-level cut-off state, and the 5V voltage provided by the external power source is reduced by the first diode D1 to obtain the initial working voltage VCC and output to the voltage conversion module 164 and the driving module 163. The first indicator light LED1 is used to indicate that the rechargeable battery 13 is charging, and the second indicator light LED2 is used to indicate that the rechargeable battery 13 is fully charged. The first indicator light LED1 can be a green light, and the second indicator light LED2 can be a blue light. When the charging socket 161 is not connected to the external power source, the first MOS transistor Q1 is in a low-level conductive state. At this time, the rechargeable battery 13 outputs the initial working voltage VCC through the first MOS transistor Q1, thereby providing the working voltage for the voltage conversion module 164 and the driving module 163.

The model of the third charging protection chip U3 can be XB5358D, which can prevent overcharging and excessive discharge of the rechargeable battery 13 through the third charging protection chip U3, ensuring the safety of the rechargeable battery 13 during use and extending its service life.

In addition, the fourth driving chip U4 outputs a PWM1 control signal to the fifth power control chip U5 through the PWM0/IO0 pin, so that the fifth power control chip U5 converts the initial working voltage VCC into the target working voltage of the first color lamp 151 and the second color lamp 152, thereby driving the first color lamp 151 and the second color lamp 152 to emit light. The fourth driving chip U4 outputs a PWM2 control signal to the first regulation module 166 through the PWM2/IO1 pin. By adjusting a duty cycle of the PWM2 control signal, the brightness of the first color lamp 151 can be adjusted. The driving chip U4 outputs a PWM3 control signal to the second regulation module 167 through the IO13/PWM1 pin. By adjusting the duty cycle of the PWM3 control signal, the brightness of the second color lamp 152 can be adjusted. When the PWM2 control signal remains low, the sixth MOS transistor Q6 is in an off state, and the first color lamp 151 is in the off state. When the PWM3 control signal remains low, the seventh MOS transistor Q7 is in the off state, and the second color lamp 152 is in the off state. Therefore, when the first color lamp 151 emits light, the second color lamp 152 can be turned off by the PWM3 control signal. When the second color lamp 152 emits light, the first color lamp 152 can be turned off by the PWM2 control signal, thereby achieving a switching between the first color lamp 151 and the second color lamp 152.

In one implementation, the switch command can be input through the mechanical button 162, and the fourth driving chip U4 can switch between the first color lamp 151 and the second color lamp 152, as well as adjust the brightness of the first color lamp 151 and the second color lamp 152 by receiving the switch command. For example, assuming that each color lamp has two brightness gears, when the mechanical button 162 is pressed for a first time, the first color lamp 151 is turned on by default. At this time, the brightness of the first color lamp 151 is in a first gear, and the second color lamp 152 is in the off state. After pressing the mechanical button 162 for a second time, the switch command is to adjust the brightness of the first color lamp 151 to a second gear. That is, after pressing the mechanical button 162 for the second time, the first color lamp 151 still lights up and the brightness is adjusted from the first gear to the second level. After pressing the mechanical button 162 for a third time, the second color lamp 152 lights up and the first color lamp 151 is in the off state. At this time, the brightness of the second color lamp 152 is in a first gear. After pressing the mechanical button 162 for a fourth time, the brightness of the second color lamp 152 is adjusted to a second gear, while the first color lamp 151 remains in the off state. After pressing the mechanical button 162 for a fifth time, the second color lamp 152 and the first color lamp 151 are both turned off. After pressing the mechanical button 162 for a sixth time, it returns to a state where the first color lamp 151 is on and the second color lamp 152 is off. This cycle is repeated, that is, the mechanical button 162 switches between different color lamps and adjusts the brightness of the color lamps for every 5 pressing cycles. Through the above ways, the function of single key switching color lamps and adjusting color lamp brightness can be achieved, achieving a purpose of color and brightness adjustments.

In other embodiments, switch commands can also be input through the touch button 168, and its working principle is the same as that of the mechanical button 162, which will not be elaborated here.

In an implementation mode, the switch command can also be input through a wireless remote-control way to achieve color lamp color switching and brightness adjustment. That is, the wireless receiving module wirelessly receives the remote-control signal of a wireless remote controller, and the fourth driving chip U4 switches color lamps and adjusts brightness based on a received remote-control signal. For example, the wireless remote controller can be provided with a first color lamp button, a second color lamp button, a first gear brightness button, a second gear brightness button, etc., and different buttons can be used to obtain corresponding remote-control signals, thereby achieving brightness and color adjustment. As shown in FIG. 10, the control circuit may further include a wireless receiving module 172, which includes a sixth receiving chip U6 and its peripheral circuit. A fourth pin and a fifth pin of the sixth receiving chip U6 are respectively connected to a ninth pin and an eighth pin of the fourth driving chip U4. The remote-control signal is wirelessly received through the sixth receiving chip U6 and transmitted to the fourth driving chip U4 so as to achieve color lamp switching and brightness adjustment.

The above examples are only used to help understand the method and core idea of the present disclosure; meanwhile, for those skilled in the art, there may be changes in the specific implementation and application scope based on the ideas of the present disclosure.
