The principles of the present invention are illustrated by implementing them in an appropriate computing environment. The following description is based on the illustrated embodiments of the present invention and should not be considered as limiting other embodiments of the present invention that are not described in detail herein.

[0022] See Figures 1 to 6 A rechargeable wall lamp 100 according to an embodiment of the present invention includes a front shell 11, a rear cover 12, a rechargeable battery 13, a carrying plate 14, a light-emitting element 15 and a circuit board 16.

[0023] The front shell 11 has a storage space 110 inside. A light-transmitting groove 111 is opened on the front side of the front shell 11, that is, the notch of the light-transmitting groove 111 is located on the front side. The front shell 111 is recessed from the front side toward the rear to form the light-transmitting groove 111. The bottom of the light-transmitting groove 111 is hollowed out to communicate with the storage space 110. The back cover 12 is fixed to the rear side of the front shell 11 to cover the storage space 110.

[0024] The carrier plate 14 is fixed to the front shell 11 and is located in the bottom hollow area of ​​the light-transmitting groove 111, so that the carrier plate 14 is exposed. The light-emitting component 15 is installed on the side surface of the carrier plate 14 facing the notch of the light-transmitting groove 111, so that the light emitted by the light-emitting component 15 is diverged from the notch of the light-transmitting groove 111 to achieve lighting. The rechargeable battery 13 and the circuit board 16 are installed in the accommodating space 110, the rechargeable battery 13 is connected to the circuit board 16, and the circuit board 16 is connected to the light-emitting body 15. The back cover 12 is also provided with a socket fixing hole 121, and the circuit board 16 is connected to a charging socket 161 for charging the rechargeable battery 13, and the charging socket 161 is fixed in the socket fixing hole 121. The circuit board 16 is used to drive the light-emitting body 15 to emit light. In the utility model, the rechargeable battery 13 is used as the power supply, so there is no need to be restricted by the position of the socket, and the wall lamp can be placed flexibly.

[0025] The front housing 11 and the rear cover 12 can be fixed by various means such as snapping, screwing, or bonding. Taking threaded connection as an example, the charging wall lamp 100 also includes a first fixing screw 171. A first threaded hole 112 is provided inside the front housing 11, and a second threaded hole 122 corresponding to the first threaded hole 112 is provided on the rear cover 12. The first fixing screw 171 is threadedly connected to the first threaded hole 112 and the second threaded hole 122 at the same time to fix the front housing 11 and the rear cover 12. The number of the first threaded hole 112, the second threaded hole 122, and the first fixing screw 171 can all be two, and each first fixing screw 171 is used to connect one first threaded hole 112 and one second threaded hole 122.

[0026] Optionally, the charging wall lamp 100 further includes a second fixing screw (not shown). The front housing 11 is provided with a first fixing hole 113, and the supporting plate 14 is provided with a second fixing hole 141 corresponding to the first fixing hole 113.

The clamping member includes a battery fixing member 181 located on the bottom wall of the accommodating space 110 and a clamping portion 182 disposed opposite the battery fixing member 181. The rechargeable battery 13 is removably clamped between the battery fixing member 181 and the clamping portion 182. The space between the rechargeable battery 13, the battery fixing member 181, and the clamping portion 182 can be an interference fit, so that the rechargeable battery 13 is more securely clamped between the battery fixing member 181 and the clamping portion 182. Of course, the rechargeable battery 13 can also be fixed to the accommodating space 110 by other means such as bonding or bundling.

[0028] Furthermore, the rechargeable wall lamp 100 also includes a magnetic member 19 and two battery fixing members 181. The battery fixing members 181 protrude relative to the bottom wall of the accommodating space 110, thereby forming an accommodating groove 1101 between the two battery fixing members 181. The magnetic member 19 is installed in the accommodating groove 1101. In addition, a protective member 20 is provided between the magnetic member 19 and the rechargeable battery 13.

[0029] Among them, the side of the back cover 12 facing away from the front shell 11 has a recessed portion 123 that is recessed toward the front shell 11. The bottom of the recessed portion 123 is arranged corresponding to the bottom of the light-transmitting groove 11, and the bottom of the recessed portion 123 is in conflict with the supporting plate 14. In order to improve the lighting brightness, a reflective layer can be coated on the side surface of the supporting plate 14 facing the notch of the light-transmitting groove 11 to reflect the light. In other embodiments, the supporting plate 14 can also be a transparent light-transmitting body, and the light of the light-emitting body 15 is emitted through the light-transmitting body. At this time, a reflective film can be coated on the side surface of the bottom of the recessed portion 123 facing the supporting plate 14 to reflect the light and improve the brightness of the light emitted from the light-transmitting groove 111.

[0030] In the embodiment of the present invention, the operation of the light-emitting body 15 can be controlled by a switch button, and the circuit board 16 can control the charging wall lamp 100 to adjust the light and color by receiving the key instruction of the switch button.

For example, a touch button 168 is set on the front side of the front shell 11, and a touch button 168 can also be set on the left or right side of the front shell 11 for easy use. The charging socket 161 can also be set in the middle of the back cover 12. It can be understood that the functions of the mechanical button 162 and the touch button 168 are the same, and both are used to control the operation of the light-emitting body 15.

[0033] The touch button 168 is disposed within the front housing 11, and a touch area is formed on the outer surface of the front housing 11. The touch area corresponds to the sensing area of ​​the touch button 168, thereby eliminating the need for a button fixing hole in the front housing 11, thereby improving the appearance. Furthermore, a button marker can be provided in the touch area to clearly identify the location of the touch button. When the touch area is activated, the button marker can light up.

[0043] The control circuit further includes a wireless receiving module, which is connected to the driving module and is used to receive wireless remote control instructions. The wireless receiving module can be, for example, an infrared receiving module or a Bluetooth receiving module.

[0044] The working principle of the control circuit of the utility model will be further described below:

[0045] When the charging port 161 is connected to an external power source, the driver chip U4 outputs a 5V_DET control signal via the AN1 / IO2 pin to between resistors R11 and R14 of the charging module 165, causing the charging chip U1 to charge the rechargeable battery 13. At this time, the MOS transistor Q1 is in a high-level cutoff state. The 5V voltage provided by the external power source is stepped down by the diode D1 to obtain the initial operating voltage VCC, which is output to the voltage conversion module 164 and the driver module 163. The indicator LED1 is used to indicate that the rechargeable battery 13 is charging, and the indicator LED2 is used to indicate that the rechargeable battery 13 is fully charged. The indicator LED1 can be green, and the indicator LED2 can be blue. When the charging port 161 is not connected to an external power source, the MOS transistor Q1 is in a low-level conduction state. At this time, the rechargeable battery 13 outputs the initial operating voltage VCC through the MOS transistor Q1, providing the operating voltage for the voltage conversion module 164 and the driver module 163.

[0046] The model of the charging protection chip U3 may be XB5358D. The charging protection chip U3 can prevent the rechargeable battery 13 from being overcharged and over-discharged, thereby ensuring the safety of the rechargeable battery 13 during use and extending the battery life.

[0047] Furthermore, the driver chip U4 outputs a PWM1 control signal to the power control chip U5 via the PWM0 / IO0 pin, causing the power control chip U5 to convert the initial operating voltage VCC to the target operating voltages for the first and second color lamps 151, 152, thereby driving the first and second color lamps 151, 152 to illuminate. The driver chip U4 outputs a PWM2 control signal to the first regulation module 166 via the PWM2 / IO1 pin. Adjusting the duty cycle of the PWM2 control signal adjusts the brightness of the first color lamp 151. The driver chip U4 outputs a PWM3 control signal to the second regulation module 167 via the IO13 / PWM1 pin. Adjusting the duty cycle of the PWM3 control signal adjusts the brightness of the second color lamp 152. Among them, when the PWM2 control signal is continuously at a low level, the MOS tube Q6 is in the cut-off state, and the first color lamp 151 is in the off state; when the PWM3 control signal is continuously at a low level, the MOS tube Q7 is in the cut-off state, and the second color lamp 152 is in the off state. Therefore, when the first color lamp 151 is lit, the second color lamp 152 can be turned off by the PWM3 control signal. When the second color lamp 152 is lit, the first color lamp 152 can be turned off by the PWM2 control signal, thereby realizing the switching between the first color lamp 151 and the second color lamp 152.

[0048] In one embodiment, a switch instruction can be input through the mechanical button 162, and the driver chip U4 realizes the switching between the first color light 151 and the second color light 152 by receiving the switch instruction, and realizes the brightness adjustment of the first color light 151 and the second color light 152. For example, assuming that each color light has two brightness levels, when the mechanical button 162 is pressed for the first time, the first color light 151 is turned on by default. At this time, the brightness of the first color light 151 is at the first level, and the second color light 152 is off. After the mechanical button 162 is pressed for the second time, the switch instruction is to adjust the brightness of the first color light 151 to the second level. That is, after the mechanical button 162 is pressed for the second time, the first color light 151 is still on, and the brightness is adjusted from the first level to the second level. After the mechanical button 162 is pressed for the third time, the second color light 152 is switched on. The first color light 151 is off, and the brightness of the second color light 152 is at the first level. After pressing the mechanical button 162 for the fourth time, the brightness of the second color light 152 is adjusted to the second level, and the first color light 151 is still off. After pressing the mechanical button 162 for the fifth time, both the second color light 152 and the first color light 151 are off. After pressing the mechanical button 162 for the sixth time, the state returns to where the first color light 151 is on and the second color light 152 is off. This cycle repeats, i.e., every five presses of the mechanical button 162 cycle through different color lights and adjusts the brightness of the color lights. In this manner, the functions of switching color lights and adjusting the brightness of the color lights can be achieved with a single button, thereby achieving the purpose of dimming.

[0049] In other embodiments, the switch command may also be input through the touch button 168 , the working principle of which is the same as that of the mechanical button 162 , and will not be described in detail here.

[0050] Optionally, you can also input switch commands through an invalid remote control to achieve color light switching and brightness adjustment, that is, the wireless receiving module wirelessly receives the remote control signal of the wireless remote controller, and the driver chip U4 performs color light switching and brightness adjustment according to the received remote control signal. For example, the wireless remote controller can be set with a first color light button, a second color light button, a first gear brightness button, a second gear brightness button, etc., and the corresponding remote control signals are obtained through different buttons to achieve dimming and color adjustment. Among them, Figure 10 As shown, the control circuit can also include a wireless receiving module 171, which includes a receiving chip U6 and its peripheral circuits. Pins 4 and 5 of the receiving chip U6 are respectively connected to pins 9 and 8 of the driving chip U4. The remote control signal is wirelessly received by the receiving chip U6 and transmitted to the driving chip U4 to realize color light switching and brightness adjustment.
