Of course, the rechargeable battery 13 can also be secured in the receiving space 110 by other means, such as by gluing or bundling.In one embodiment, the rechargeable wall lamp 100 further includes a magnetic suction member 19 and two battery fastening members 181.

[0027] The operating principle of the control circuit of the present invention is explained in more detail below.

[0028] When the charging socket 161 is connected to the external power source, the fourth drive chip U4 outputs a 5V_DET control signal via the AN1 / IO2 pin to the charging module 165, which is arranged 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 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 and output it to the voltage converter module 164 and the drive module 163. The first indicator light LED1 indicates that the rechargeable battery 13 is being charged, and the second indicator light LED2 indicates 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 conduction state. At this time, the rechargeable battery 13 outputs the initial operating voltage VCC through the first MOS transistor Q1, thereby providing the operating voltage for the voltage converter module 164 and the drive module 163.

[0029] The model of the third charge protection chip U3 can be XB5358D, which can prevent overcharging and excessive discharge of the rechargeable battery 13 by the third charge protection chip U3, ensuring the safety of the rechargeable battery 13 during use and extending its service life. Furthermore, the fourth drive chip U4 outputs a PWM1 control signal to the fifth power control chip U5 via the PWM0 / IO0 pin, so that the fifth power control chip U5 converts the initial operating voltage VCC into the target operating 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 drive chip U4 outputs a PWM2 control signal to the first control module 166 via 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 drive chip U4 outputs a PWM3 control signal to the second control module 167 via the IO13 / PWM1 pin. By adjusting the duty cycle of the PWM3 control signal, the brightness of the second color lamp 152 can be controlled. When the PWM2 control signal remains low, the sixth MOS transistor Q6 is off, and the first color lamp 151 is off. When the PWM3 control signal remains low, the seventh MOS transistor Q7 is off, and the second color lamp 152 is off. Therefore, the second color lamp 152 can be turned off by the PWM3 control signal when the first color lamp 151 is lit. When the second color lamp 152 is lit, 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.

[0030] In one embodiment, the switching command can be input via the mechanical button 162, and the fourth drive chip U4 can switch between the first color lamp 151 and the second color lamp 152, and adjust the brightness of the first color lamp 151 and the second color lamp 152 by receiving the switching command. For example, assuming that each color lamp has two brightness levels, the first time the mechanical button 162 is pressed, the first color lamp 151 is turned on by default. At this time, the brightness of the first color lamp 151 is at a first level, and the second color lamp 152 is in the off state. After a second press of the mechanical button 162, the switching command is to adjust the brightness of the first color lamp 151 to a second level.That is, after the second press of the mechanical button 162, the first color lamp 151 continues to light up and the brightness is adjusted from the first level to the second level. After a third press of the mechanical button 162, the second color lamp 152 lights up and the first color lamp 151 is off. At this time, the brightness of the second color lamp 152 is at a first level. After the fourth press of the mechanical button 162, the brightness of the second color lamp 152 is adjusted to a second level, while the first color lamp 151 remains in the off state. After the fifth press of the mechanical button 162, both the second color lamp 152 and the first color lamp 151 are turned off. After the sixth press of the mechanical button 162, the circuit returns to the state in which the first color lamp 151 is on and the second color lamp 152 is off. This cycle repeats, i.e.The mechanical knob 162 switches between the different color lamps and adjusts the brightness of the color lamps for every 5 printing cycles. In this way, the function of switching the color lamps and adjusting the brightness of the color lamps can be achieved with a single knob, thereby achieving the purpose of color and brightness adjustment.

[0031] In other embodiments, switching commands can also be entered via the touch button 168, the operating principle of which is the same as that of the mechanical button 162, which will not be discussed in detail here.

[0032] In one embodiment, the switching command can also be input wirelessly via remote control to enable color change and brightness control of the lamp. That is, the wireless receiving module wirelessly receives the remote control signal from a wireless remote control, and the fourth drive chip U4 switches the color lamps and adjusts the brightness based on the received remote control signal. For example, the wireless remote control can be provided with a button for a first color lamp, a button for a second color lamp, a button for the first level of brightness, a button for the second level of brightness, etc., and different buttons can be used to receive corresponding remote control signals, thereby adjusting the brightness and color. As shown in Fig.As shown in Figure 10, the control circuit may further include a wireless receiving module 172 comprising a sixth receiving chip U6 and its peripheral circuitry. A fourth pin and a fifth pin of the sixth receiving chip U6 are connected to a ninth pin and an eighth pin of the fourth driving chip U4, respectively. The remote control signal is wirelessly received via the sixth receiving chip U6 and transmitted to the fourth driving chip U4 to achieve color lamp switching and brightness adjustment.
