[0023] In order to achieve the aesthetic design of the cabinet, traditional cabinet lights usually adopt an embedded design to assist the local lighting of the cabinet. At the same time, the cabinet light is powered by a battery inside it to maintain normal operation. However, most cabinet lights do not have a power indication, and users cannot intuitively see the power consumption of the cabinet light and cannot estimate its usage time, which brings inconvenience to users when the power of the cabinet light runs out.

[0024] Therefore, in order to improve the convenience of users using cabinet lights, the present invention proposes a cabinet light, referring to Figure 1 , the cabinet light includes:

[0025] a light strip, a battery, and a display circuit 30;

[0026] a voltage detection circuit 10, the voltage detection circuit 10 is connected to the battery, and the voltage detection circuit 10 is used to detect the voltage of the battery and output a voltage signal;

[0027] The main control circuit 20, the control terminals of the main control circuit 20 are respectively connected to the display circuit 30 and the light strip, and the input terminal of the main control circuit 20 is connected to the voltage detection circuit 10;

[0028] The main control circuit 20 is used to control the display circuit 30 to display the battery power according to the voltage signal of the voltage detection circuit 10 when controlling the light strip to emit light.

[0029] It can be understood that, in order to achieve the aesthetic design of the cabinet, traditional cabinet lights usually adopt an embedded design to embed the cabinet lights into the cabinet to assist in the local lighting of the cabinet. At the same time, in order to avoid the complicated wiring affecting the aesthetics of the cabinet, the cabinet lights are powered by the batteries inside them to maintain normal operation. However, most cabinet lights do not have a battery power reminder, and users cannot intuitively see the battery power of the cabinet lights, and thus cannot estimate the usage time of the cabinet lights. When the battery power of the cabinet lights is exhausted, the lighting function cannot be realized, which brings inconvenience to users. Therefore, the present utility model proposes a cabinet light, and the voltage detection circuit 10 is arranged in the cabinet light so that the cabinet light has a battery power display function, and users can charge the cabinet light in time according to the displayed power of the cabinet light, avoiding the lighting function cannot be realized when the battery power of the cabinet light is exhausted, thereby bringing convenience to users in using the cabinet light.

[0030] In this embodiment, the cabinet light includes a light strip, a battery, a display circuit 30, a voltage detection circuit 10, and a main control circuit 20. The light strip is used to work and emit light when triggered by the main control circuit 20; the battery is used to supply power to other functional circuits such as the light strip, the display circuit 30, the voltage detection circuit 10, and the main control circuit 20; the voltage detection circuit 10 is used to detect the battery power in real time; the display circuit 30 is used to display the battery power when controlled by the main control circuit 20 to remind the user of the current battery power of the cabinet light; the main control circuit 20 serves as the main circuit and is used to control other functional circuits such as the light strip, the display circuit 30, and the voltage detection circuit 10 to work according to the user's trigger signal.

[0031] Optionally, the main control circuit 20 can be implemented by a main control chip, such as an MCU, a DSP (Digital Signal Process, digital signal processing chip), an FPGA (Field Programmable Gate Array, programmable logic gate array chip), etc.; the display circuit 30 can be implemented by an LED display screen, a touch screen, a digital tube. In this embodiment, the display circuit 30 is implemented by a digital tube, the voltage detection circuit 10 is implemented by an ADC detection circuit, and the main control circuit 20 is implemented by an MCU. Among them, the MCU has a CK-BAT pin for receiving the signal of the voltage detection circuit 10, and an LED pin for controlling the operation of the light strip.

[0032] In practical applications, referring to Figure 3 , the ADC detection circuit is an analog-to-digital conversion circuit, including a fourth resistor R4, a sixth resistor R6, and a sixth capacitor C6. The voltage of the battery is detected through the fourth resistor R4, the sixth resistor R6, and the sixth capacitor C6, and the voltage of the battery is converted into a digital signal, and then converted into a voltage signal for characterizing a percentage value according to the digital signal, and finally the voltage signal is sent to the CK-BAT pin of the MCU. The MCU determines the working mode of the cabinet lamp according to the user's trigger action, and controls the light strip to emit light according to the working mode. When the MCU controls the light strip to be in the light-emitting state, the percentage value is determined according to the voltage signal sent by the ADC detection circuit, and the corresponding percentage value is controlled to be displayed on the digital tube. Among them, the digital tube is composed of multiple light-emitting diodes, and the MCU controls the multiple light-emitting diodes to emit light, so that the light-emitting diodes in the light-emitting state achieve different combination modes, thereby displaying digital information from 0 to 9, thereby prompting the user of the percentage value of the current battery. The user can charge the cabinet lamp in time according to the power displayed by the cabinet lamp, so as to avoid the inability to realize the lighting function when the battery power of the cabinet lamp is exhausted.

[0033] It should be understood that referring to Figure 3 , the cabinet lamp further includes a light strip control circuit 90. The light strip control circuit 90 has a light strip interface CN1 for connecting the light strip, and the light strip control circuit 90 is composed of a first MOS transistor Q1, an eleventh resistor R11, a twelfth resistor R12, a fifteenth resistor R15, and a seventeenth resistor R17. The MCU controls the light strip to be in the light-emitting state specifically as follows: output a control signal to the first MOS transistor Q1 through the LED pin to control the first MOS transistor Q1 to conduct, so as to conduct the path between the battery and the light strip, thereby controlling the light strip to be in the light-emitting state.

[0034] The present utility model provides a cabinet lamp, which includes: a light strip, a battery, a display circuit 30, a voltage detection circuit 10, and a main control circuit 20; the voltage detection circuit 10 is connected to the battery; the control end of the main control circuit 20 is respectively connected to the display circuit 30 and the light strip, and the input end of the main control circuit 20 is connected to the voltage detection circuit 10. In practical applications, the voltage detection circuit 10 is used to detect the voltage of the battery and output a voltage signal to the main control circuit 20; the main control circuit 20 is used to control the display circuit 30 to display the battery power according to the voltage signal of the voltage detection circuit 10 when controlling the light strip to emit light, so that the cabinet lamp has the function of displaying the battery power.

[0035] In an embodiment, referring to Figure 3 , the display circuit 30 includes:

[0036] Multiple light-emitting diodes;

[0037] The control terminals of the main control circuit 20 are respectively connected to a plurality of the light-emitting diodes; the main control circuit 20 is specifically configured to control the plurality of light-emitting diodes to emit light according to the voltage signal of the voltage detection circuit 10, so as to display the power of the battery.

[0038] It can be understood that, in this embodiment, the display circuit 30 is implemented by using a digital tube, and the digital tube includes a display tube and a plurality of light-emitting diodes. The plurality of light-emitting diodes respectively form a first driving circuit, a second driving circuit, a third driving circuit, a fourth driving circuit, and a fifth driving circuit.

[0039] Among them, the MCU also has a first pin, a second pin, a third pin, a fourth pin, and a fifth pin for receiving signals of a plurality of driving circuits. The first driving circuit, the second driving circuit, the third driving circuit, the fourth driving circuit, and the fifth driving circuit are respectively connected to the first pin, the second pin, the third pin, the fourth pin, and the fifth pin of the MCU. In practical applications, the MCU controls the light strip to emit light according to the user's trigger action, and controls the first driving circuit, the second driving circuit, the third driving circuit, the fourth driving circuit, and the fifth driving circuit to work according to the percentage value, so as to alternately light up a plurality of light-emitting diodes in a scanning manner to display the battery power.

[0040] In one embodiment, referring to Figure 2 , the cabinet light further includes:

[0041] A human body sensing circuit 40, the human body sensing circuit 40 is connected to the input end of the main control circuit 20, and the human body sensing circuit 40 is configured to output a human body sensing signal to the main control circuit 20 when a human body is sensed;

[0042] A light strip control circuit 90, the input end of the light strip control circuit 90 is connected to the battery, and the output end of the light strip control circuit 90 is connected to the light strip;

[0043] The main control circuit 20 is further configured to control the light strip control circuit 90 to conduct the path between the battery and the light strip when receiving the human body sensing signal.

[0044] It can be understood that most traditional cabinet lights use the infrared pair tube method to achieve light emission. When using the infrared pair tube method to achieve light emission, the sensing distance of the infrared pair tube is relatively short, resulting in limited sensing range. In order to expand the sensing range of the cabinet light, this embodiment replaces the infrared pair tube method with the PIR method to achieve the function of the cabinet light sensing and emitting light through the PIR method. The human body sensing circuit 40 in this embodiment is implemented by using a D210AX pyroelectric sensor, and the main control circuit 20 is implemented by using an MCU. Among them, the MCU also has a PIR pin for receiving the signal of the human body sensing circuit 40.

[0045] Specifically, when a user enters the sensing range of the D210AX pyroelectric sensor, the D210AX pyroelectric sensor senses the infrared radiation emitted by the human body and outputs a human body sensing signal to the PIR pin of the MCU. The MCU receives the human body sensing signal, confirms that someone is currently near the cabinet light, and controls the strip light control circuit 90 to conduct the path between the battery and the strip light, so that the battery outputs voltage to the strip light, causing the strip light to emit light, thereby realizing the function of the cabinet light sensing and emitting light.

[0046] In one embodiment, referring to Figure 2 and Figure 3 , the cabinet light further includes:

[0047] An ambient light detection circuit 50, the ambient light detection circuit 50 is connected to the input end of the main control circuit 20, and the ambient light detection circuit 50 is used to detect ambient light and output an ambient light detection signal to the main control circuit 20 according to the ambient light;

[0048] The main control circuit 20 is further configured to control the strip light control circuit 90 to conduct / turn off the path between the battery and the strip light according to the ambient light detection signal.

[0049] It can be understood that in order to improve the energy-saving level of the cabinet light, in the daytime or in an environment with sufficient light, the cabinet light does not light up; in the night or in an environment with weak light, the cabinet light lights up according to the working mode. In this embodiment, the ambient light detection circuit 50 is implemented by a photosensitive triode CDS, a photosensitive resistor R29, and a photosensitive capacitor C0. Among them, the MCU also has a CDS pin for receiving the signal of the ambient light detection circuit 50.

[0050] Specifically, in the daytime or in an environment with sufficient light, the photosensitive triode CDS is in a conducting state, and the voltage value output by the emitter of the photosensitive triode CDS is approximately the power supply voltage. At this time, the voltage at the connection point between the first end of the photosensitive resistor R29 and the first end of the photosensitive capacitor C0 is approximately the power supply voltage, that is, a high level. The ambient light detection circuit 50 converts the high level into a high level signal and outputs it to the CDS pin of the MCU. The MCU determines that the cabinet light does not light up according to the high level signal, that is, controls the strip light control circuit 90 to turn off the path between the battery and the strip light. In the night or in an environment with weak light, the photosensitive triode CDS is in an off state, and the voltage value output by the emitter of the photosensitive triode CDS is approximately zero. At this time, the voltage at the connection point between the first end of the photosensitive resistor R29 and the first end of the photosensitive capacitor C0 is approximately zero, that is, a low level; the ambient light detection circuit converts the low level into a low level signal and outputs it to the CDS pin of the MCU. The MCU determines that the cabinet light lights up according to the low level signal, that is, controls the strip light control circuit 90 to conduct the path between the battery and the strip light.

[0051] In one embodiment, referring to Figure 2 , the cabinet lamp further includes:

[0052] A trigger button for outputting a trigger signal when triggered by a user;

[0053] A brightness touch circuit 60, an input end of the brightness touch circuit 60 is connected to the trigger button, and an output end of the brightness touch circuit 60 is connected to the main control circuit 20; the brightness touch circuit 60 is configured to output a brightness adjustment signal according to the trigger signal of the trigger button;

[0054] The main control circuit 20 is further configured to correspondingly adjust the brightness of the light strip according to the brightness adjustment signal by controlling the light strip control circuit 90.

[0055] It can be understood that in this embodiment, the trigger button specifically includes a brightness increase button and a brightness decrease button; the brightness touch circuit 60 specifically includes an eighth resistor and a ninth resistor. The MCU also has a brightness increase pin LED+ and a brightness decrease pin LED- for receiving signals from the brightness touch circuit 60. Specifically, when the user needs to increase the brightness of the cabinet lamp, touch the brightness increase button, and the electrical signal generated by the brightness increase button passes through the eighth resistor and is output to the brightness increase pin LED+ of the MCU in the form of a brightness increase signal, and the MCU controls the light strip control circuit 90 to increase the brightness of the light strip; when the user needs to decrease the brightness of the cabinet lamp, touch the brightness decrease button, and the electrical signal emitted by the brightness decrease button passes through the ninth resistor and is output to the brightness decrease pin LED- of the MCU in the form of a brightness decrease signal, and the MCU controls the light strip control circuit 90 to decrease the brightness of the light strip.

[0056] In one embodiment, referring to Figure 2 , the cabinet lamp further includes:

[0057] A trigger button for outputting a trigger signal when triggered by a user;

[0058] A working mode touch circuit 80, an input end of the working mode touch circuit 80 is connected to the trigger button, and an output end of the working mode touch circuit 80 is connected to the main control circuit 20; the working mode touch circuit 80 is configured to output a working mode switching signal according to the trigger signal of the trigger button;

[0059] The main control circuit 20 is further configured to switch to the corresponding working mode according to the working mode switching signal; the working modes include a constant-on mode, a human body induction mode, and a light control induction mode.

[0060] It can be understood that in this embodiment, the trigger button specifically includes a working mode switching button; the working mode touch circuit 80 specifically includes a tenth resistor, and the MCU also has a working mode pin AUTO for receiving the signal of the working mode touch circuit 80. Specifically, when the user touches the working mode switching button, the electrical signal generated by the working mode switching button passes through the tenth resistor and is output to the working mode pin AUTO of the MCU in the form of a working mode switching signal. The MCU determines the corresponding working mode according to the working mode switching signal and controls the cabinet light to switch to the constant-on mode, the human body induction mode, or the light control induction mode.

[0061] In one embodiment, referring to Figure 2 , the cabinet light further includes:

[0062] A trigger button for outputting a trigger signal when triggered by the user;

[0063] A switch touch circuit 70, the input end of the switch touch circuit 70 is connected to the trigger button, and the output end of the switch touch circuit 70 is connected to the main control circuit 20; the switch touch circuit 70 is used for outputting a switch control signal according to the trigger signal of the trigger button;

[0064] The main control circuit 20 is further used for controlling the conduction / shutdown of the path between the battery and the light strip by the light strip control circuit 90 according to the switch control signal.

[0065] It can be understood that in this embodiment, the trigger button specifically includes a switch button; the switch touch circuit 70 specifically includes a seventh resistor. The MCU also has a switch pin ON / OFF for receiving the signal of the switch touch circuit 70. Specifically, when the user touches the switch button, the electrical signal generated by the switch button passes through the seventh resistor and is output to the switch pin ON / OFF of the MCU in the form of a switch control signal. When the MCU determines that the cabinet light needs to be turned off according to the switch control signal, it controls the light strip control circuit 90 to cut off the path between the battery and the light strip, so that the light strip does not emit light. At this time, even if the cabinet light is in the human body induction mode and there is a user within the induction range of the cabinet light, the MCU will not control the light strip to emit light; when the MCU determines that the cabinet light needs to be turned on according to the switch control signal, it controls the light strip control circuit 90 to conduct the path between the battery and the light strip, so that the light strip emits light.

[0066] In one embodiment, referring to Figure 2 , the cabinet light further includes:

[0067] A charging interface for connecting to an external power source;

[0068] A charging circuit, the input end of the charging circuit is connected to the charging interface, and the output end of the charging circuit is connected to the battery; the charging circuit is used to convert the external power source connected to the charging interface and then output it to the battery.

[0069] It can be understood that the voltage of the external power source may be greater than the battery voltage. If the battery is directly connected to the external power source for charging, it will damage the battery. For example, if the battery voltage is 4.2V and the charging voltage is 5V, directly connecting the battery will cause the charging current to be too large and damage the battery. Therefore, a charging circuit is also provided in this embodiment to protect the battery for safe charging.

[0070] Optionally, the charging circuit can be implemented by a charging management chip and a charging IC. The charging circuit of this embodiment is implemented by a charging chip with the model number ME4057. Specifically, the charging chip has a power input pin, and the power input pin of the charging chip is used to connect to the USB charging interface, and the USB charging interface is used to access the external power source; when the external power source inputs the power voltage through the USB charging interface, the charging chip receives and adjusts the power voltage, and adjusts the voltage value within a preset range; the charging chip outputs the adjusted voltage to the battery, thereby protecting the battery for stable charging.

[0071] In one embodiment, referring to Figure 2 , the cabinet light further includes:

[0072] A charging detection circuit, the input end of the charging detection circuit is connected to the charging interface, and the output end of the charging detection circuit is connected to the main control circuit 20; the charging detection circuit is used to output a charging detection signal to the main control circuit 20 when it detects that the charging interface accesses an external power source;

[0073] The main control circuit 20 is further used to control the display circuit 30 to display a charging mark when receiving the charging detection signal.

[0074] It can be understood that in this embodiment, the MCU also has a detection pin CK-VIN for receiving the signal of the charging detection circuit. The charging detection circuit includes a third resistor and a fifth resistor, and the connection point between the third resistor and the fifth resistor is connected to the detection pin CK-VIN of the MCU. In actual application, when the charging interface accesses an external power source, the external power source passes through the third resistor and the fifth resistor, and the electrical signals generated by the third resistor and the fifth resistor are sent to the detection pin CK-VIN of the MCU in the form of a charging detection signal through the connection point. When the MCU receives the charging detection signal, it confirms that the charging interface accesses an external power source and controls the digital tube to display a charging mark.

[0075] In one embodiment, referring to Figure 2 , the cabinet light further includes:

[0076] A voltage stabilizing circuit, the input end of the voltage stabilizing circuit is connected to the battery, and the output end of the voltage stabilizing circuit is connected to the main control circuit 20; the voltage stabilizing circuit is used to stabilize the voltage of the battery and then output it to the main control circuit 20.

[0077] It can be understood that the voltage stabilizing circuit can convert the voltage of the battery and then output it to other devices to meet the working voltage requirements of other devices.

[0078] Optionally, the voltage stabilizing circuit can be implemented by a voltage stabilizing chip, a step-up / step-down chip, an LDO chip (Low Dropout Regulator), a TL431 module, etc. The voltage stabilizing circuit in this embodiment is implemented by a voltage stabilizing chip with the model number AS7130. Among them, the MCU also has a power supply pin VDD for receiving the voltage of the voltage stabilizing circuit. Specifically, the battery outputs voltage to the voltage stabilizing chip. After the voltage conversion process of the voltage stabilizing chip, the voltage stabilizing chip outputs a stable voltage to other functional circuits such as the power supply pin VDD of the MCU, the human body sensing circuit 40, and the ambient light detection circuit 50 to provide power for multiple functional circuits. For example: the voltage output by the battery is 12V, which is converted into a 3.3V supply voltage by the voltage stabilizing chip, and the 3.3V supply voltage is respectively output to the power supply pin VDD of the MCU, the power supply end of the human body sensing circuit 40, and the power supply end of the display circuit 30. Through the above settings, it can meet the working voltage requirements of different devices on the circuit. At the same time, it can also be compatible with other devices with different working voltages, thereby improving the compatibility of the closet lamp with devices and making it scalable.

[0079] The above embodiments are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
