[0002] With the development of power strips, their application has become increasingly widespread. Some smart power strips allow users to determine the status of the power strip through the status of its indicator lights.

[0028] The present application will be further described below with reference to the accompanying drawings.
[0029] like Figure 1 As shown, Figure 1 This is a schematic block diagram of the structure of an intelligent light-sensing adjustable power strip according to an embodiment of this application. The intelligent light-sensing adjustable power strip includes several socket modules for power output, indicator lights for indicating the working status of the power strip, a light-sensing module, and a main control module.
[0030] The indicator lights have different lighting modes corresponding to different working states of the power strip;
[0031] The light sensor module is used to detect ambient light intensity;
[0032] The main control module is connected to the indicator light and the light sensor module respectively, and is used to control the lighting mode of the indicator light and adjust the brightness of the indicator light according to the ambient light intensity detected by the light sensor module.
[0033] Understandably, the smart light-sensing adjustable power strip includes several socket modules for power output. These socket modules provide the basic power supply function of the power strip. Each socket module contains multiple physical connection terminal groups and coupled conductive contact mechanisms. These conductive contact mechanisms are configured to form a pluggable electrical connection with the power plug-in devices of external electrical appliances. In other words, the socket module is for users to connect various electrical appliances. When a user inserts the power plug of an appliance into the socket module, the metal contacts of the plug contact with the copper contacts inside the socket, forming a closed circuit, thereby enabling the transfer of electrical energy from the power strip to the appliance. In this embodiment, the power strip may include one or more socket modules. Each socket module may include a circuit portion for power output sockets. Each socket module may include two or three standard sockets, such as those conforming to Chinese national standards, American standards, or European standards, to accommodate different types of power plugs. Furthermore, the sockets of the socket module may be designed with safety shutters that only open when a plug is correctly inserted, effectively preventing children from accidentally touching them and preventing foreign objects from entering. In addition, in some embodiments, the socket module may include an intelligent identification unit that can identify the type and power requirements of the connected electrical appliance, thereby adjusting the current output to provide the most suitable power supply solution for the appliance.
[0034] Understandably, the smart light-sensing power strip also includes a housing structure. The socket module, light-sensing module, and main control module can be housed within the housing structure. The light-sensing module can also be embedded in the side wall of the housing, and the indicator light can be placed on the surface of the housing structure.
[0035] In this embodiment, the indicator light can be an LED light, and the indicator light can be a monochrome or multi-color LED array. In one embodiment, the indicator light can be lit by a driving circuit module. The driving circuit module can drive different combinations of light parameters according to a preset encoding protocol, including but not limited to color temperature gradient, flashing frequency, and light intensity distribution mode. In addition, the indicator light is used to indicate the working status of the power strip. That is, the power strip can have a variety of different working states, such as the standby state when the power strip is connected to the power supply but no appliance is plugged in, the normal working state when an appliance is plugged in and turned on, the overload protection state when the total power of the connected appliances exceeds the rated power of the power strip, the short circuit protection state when a short circuit occurs in the internal or external wiring of the socket, the intelligent control state for remote control sockets with intelligent functions, and the energy-saving state in energy-saving mode. For each working state of the power strip, the indicator light can have different lighting modes. For example, different colors of the indicator light can indicate different working states of the power strip, different color temperatures of the indicator light can indicate different working states of the power strip, and the constant light or flashing states of the indicator light can indicate different working states of the power strip.
[0036] The photosensing module includes a photosensitive element, which can be a photoresistor, a photodiode, or a phototransistor. The resistance of the photoresistor changes with the light intensity, while the photodiode or phototransistor generates current under light. Therefore, the light intensity can be determined by the change in resistance or current. In addition, since the signal generated by the photosensitive element may be weak, the photosensing module may also include an amplifier circuit to enhance the signal so that it can be correctly read by subsequent circuits or microprocessors.
[0037] The main control module is connected to both the indicator light and the light sensor module. In this embodiment, the main control module can be a microcontroller (MCU), integrating a processor, memory, input / output interfaces, and other functions. Additionally, the main control module may include a power management circuit to provide stable power to the main control module and other related circuits, a communication interface such as I2C, SPI, or UART for communicating with other modules or external devices, and input / output ports for connecting external devices such as indicator lights and light sensors. Thus, the main control module can collect ambient light brightness data from the light sensor module through the input port. The microcontroller processes the collected data and determines whether the ambient light brightness reaches a set threshold based on a preset algorithm. Based on the processing result, the main control module sends a control signal to the indicator light through the output port.
[0038] In one embodiment, if the photosensitive module outputs an analog signal (such as the resistance change of a photoresistor), the analog input port (such as an ADC) of the main control module can be directly connected to the output of the photosensitive module; if the photosensitive module has a built-in ADC converter and outputs a digital signal, it can be connected to the main control module through digital interfaces such as I2C and SPI; in addition, the GPIO (General Purpose Input / Output) port of the main control module can be directly connected to an indicator light, and the indicator light can be switched on and off by controlling the high and low levels of the GPIO. If the indicator light requires a large current, the control signal can be amplified by a driving circuit (such as a transistor or MOSFET) to drive the indicator light.
[0039] In one embodiment, the main control module can establish a bidirectional communication link with the indicator light through a digital signal interface bus, form a power management path with the socket module through a power control interface, and achieve data interaction with the light sensor module through a sensor data channel. In operation, the main control module can obtain the quantitative parameters of the light sensor module in real time, generate an adaptive brightness adjustment coefficient based on an automatic dimming control algorithm, and adjust the optical output power of the indicator light according to the adaptive brightness adjustment coefficient.
[0040] In one embodiment, the main control module may include: a microprocessor and a storage medium connected in communication, the storage medium containing a brightness control logic program; a signal processing channel connected to a light sensor module to receive an ambient brightness dataset; and a mode control interface for establishing bidirectional command interaction with an environmental status indicator unit. The main control module is coupled to the socket module via a power management node, and when running the brightness control logic program, it parses the ambient brightness dataset to generate a dynamic compensation coefficient, and synchronously adjusts the base luminous intensity of the indicator light based on the dynamic compensation coefficient.
[0041] In some embodiments of the smart light-sensing adjustable power strip provided in this application, such as Figure 2 As shown, Figure 2 This is a schematic block diagram of the structure of an intelligent light-sensing adjustable power strip provided in another embodiment of this application. The power strip also includes a circuit protection module, which is connected to the main control module and the socket module respectively. The lighting mode includes a protective lighting mode. The main control module is also used to control the indicator light to illuminate in the protective lighting mode when the circuit protection module is triggered.
[0042] Understandably, a power strip is a device that allows users to connect various electrical appliances to obtain electrical energy. It provides power to users through the circuitry within the power strip. Therefore, a power strip should also include a circuit protection module to ensure that it can safely provide power to users.
[0043] The circuit protection module includes circuit protection devices. For example, the circuit protection module may include a circuit breaker for automatically disconnecting the circuit when the current exceeds a set value to prevent overload; a fuse for melting to cut off the circuit when the current is too large; a varistor for conducting when the voltage exceeds a safe level to protect the circuit; a silicon controlled rectifier circuit for overvoltage protection by triggering the circuit to disconnect; an undervoltage protection circuit for protecting the equipment from voltages below normal operating voltage; a residual current device (RCD) for quickly cutting off the power supply to prevent electric shock when a leakage current exceeds a predetermined value; and a surge protector for protecting the equipment from voltage spikes and surges. The circuit protection module includes at least one of the above-mentioned circuit protection devices. In one embodiment, the circuit protection module may include multiple of the above-mentioned circuit protection devices simultaneously, that is, multiple circuit protection devices are integrated into the circuit protection module to enable the power strip to have multiple circuit protection functions.
[0044] The circuit protection module is connected to both the main control module and the socket module. The main control module monitors the circuit status and controls the circuit protection module's actions as needed. It receives signals from the circuit protection module, such as overload, short circuit, or leakage current, and responds accordingly. The main control module is also connected to the socket module to control power supply. It monitors the current usage of each socket module to ensure stable and safe power supply. In one embodiment, the main control module continuously monitors the current and voltage in the circuit, as well as other parameters such as temperature and leakage current. When an abnormality is detected, the main control module analyzes the data to determine if protective measures are necessary. For example, if the current exceeds a set value (overload or short circuit), the main control module sends a signal to the circuit protection module to activate the circuit breaker or fuse, thereby cutting off the power. For instance, in the case of leakage current protection, if leakage current is detected, the main control module immediately instructs the RCD to activate and quickly disconnect the power. In one embodiment, the main control module can also control the power switch of the socket module, allowing the user to manually control the power supply.
[0045] It's understandable that the lighting modes include a protective lighting mode. The main control module is also used to control the indicator lights to illuminate in the protective lighting mode when the circuit protection module is triggered. In other words, the main control module can monitor each socket module in real time and is connected to the circuit protection module. In the event of a circuit abnormality, the main control module will send a corresponding signal to the circuit protection module to trigger its protection action. When the circuit protection module is triggered, the main control module will send a corresponding signal to control the indicator lights to illuminate in the protective lighting mode, thus alerting the user to the abnormality of the power strip. It's also understandable that the protective lighting mode differs from the lighting modes during normal operation of the power strip. The protective lighting mode can be a more conspicuous mode so that users can notice it promptly; for example, the protective lighting mode could be high-frequency flashing.
[0046] In some embodiments of the present application, the intelligent light-sensing adjustable power strip includes a circuit protection module comprising a short-circuit protection unit, an undervoltage protection unit, and an overcurrent protection unit.
[0047] It is understood that the circuit protection module can include multiple circuit protection devices at the same time, that is, multiple circuit protection devices are integrated into the circuit protection module so that the power strip can have multiple circuit protection functions. In this embodiment, the circuit protection module includes one or more of a short circuit protection unit, an undervoltage protection unit, and an overcurrent protection unit. The short circuit protection unit, the undervoltage protection unit, and the overcurrent protection unit are used to implement different circuit protection functions.
[0048] In some embodiments of the smart light-sensing adjustable power strip provided in this application, such as Figure 3 As shown, Figure 3 This is a circuit diagram of an intelligent light-sensing adjustable power strip provided in another embodiment of this application. The main control module is also used to detect the output power of the power strip and control the lighting mode of the indicator light according to the output power of the power strip.
[0049] In this embodiment, the main control module can be the microcontroller U3 in the MCU circuit. The microcontroller U3 includes multiple control pins, and different functions can be realized through the control pins of the microcontroller U3, such as circuit detection, circuit control, filtering, etc. In this embodiment, the microcontroller U3 can detect the output power of the power strip through the control pins, and control the lighting mode of the indicator light according to the output power of the power strip through different control pins.
[0050] For example, the microcontroller U3 can detect the current flowing through the power strip by connecting a pin to a current sensor. The current sensor can be a shunt resistor, a Hall effect sensor, or other types of sensor. When current flows through the sensor, a voltage signal proportional to the current is generated across the sensor. The microcontroller U3 can read this voltage signal through an analog input pin (such as an ADC pin) and calculate the actual current value. Similarly, the microcontroller U3 can detect the output voltage of the power strip through an analog input pin and reduce the output voltage to a range that the microcontroller U3 can safely read by using a voltage divider resistor network. After obtaining the current and voltage readings, the real-time output power can be calculated.
[0051] In one embodiment, the microcontroller U3 can use digital output pins to control relays, transistors, or other switching elements to turn the power output of the power strip on or off. Alternatively, if it is necessary to adjust the output power (e.g., for an adjustable power supply), the microcontroller U3 can use PWM pins to control a switching element to adjust the voltage or current in a fixed-frequency pulse manner.
[0052] In some embodiments of this application, the intelligent light-sensing adjustable power strip is controlled to keep the indicator light on in a constant-on mode when the output power of the power strip is not greater than a first preset power value.
[0053] Understandably, after the main control module detects and obtains the power strip's output power, it can compare the power strip's output power with a first preset power value. The first preset power value can be a power threshold indicating that the power strip is in normal working condition. If the power strip's output power is greater than the first preset power value, it indicates that the power strip's output power is relatively high, and the power strip is in a high-load state, that is, multiple high-power appliances are connected to the power strip, or some individual high-power appliances are in use, resulting in an increase in total output power. At this time, if the output power is close to or exceeds the maximum load capacity designed for the power strip, there may be an overload risk. Therefore, when the power strip's output power is not greater than the first preset power value, the indicator light can be controlled to stay on to indicate to the user that the power strip is currently in normal use.
[0054] Understandably, if the power strip's output power is not greater than the first preset power value, the indicator light can also be controlled to illuminate in other modes. The power strip's status corresponding to each lighting mode can be marked in the product manual to indicate the current usage status of the power strip to the user.
[0055] In some embodiments of this application, the intelligent light-sensing adjustable power strip is controlled to illuminate in a breathing mode when the output power of the power strip is not less than a first preset power value and not greater than a second preset power value.
[0056] Understandably, after the main control module detects and obtains the power strip's output power, it can compare the power strip's output power with a first preset power value and a second preset power value. The first preset power value can be a power threshold indicating that the power strip is in a normal working state, while the second preset power value can be a power threshold indicating that the power strip is in a high-risk state. If the power strip's output power is greater than the first preset power value, it indicates that the power strip's output power is relatively high, and the power strip is in a high-load state, that is, multiple high-power appliances are connected to the power strip, or some individual high-power appliances are in use, resulting in an increase in total output power. If the power strip's output power is greater than the second preset power value, it indicates that the power strip's output power is too high, and the power strip is in a high-risk state. Therefore, if the power strip's output power is not less than the first preset power value and not greater than the second preset power value, the indicator light can be controlled to light up in a breathing mode to indicate to the user that the current power strip is in a high-risk state.
[0057] Understandably, if the power strip's output power is not less than the first preset power value and not greater than the second preset power value, the indicator light can also be controlled to illuminate in other modes. The power strip's status corresponding to each lighting mode can be marked in the power strip's product instruction manual to indicate the current usage status of the power strip to the user.
[0058] In some embodiments of this application, the intelligent light-sensing adjustable power strip is controlled to light up in a flashing mode when the output power of the power strip is not less than a third preset power value.
[0059] Understandably, after the main control module detects and obtains the output power of the power strip, it can compare the output power of the power strip with the third preset power value. The third preset power value can be the power threshold that indicates that the power strip is in an overload state. If the output power of the power strip is greater than the third preset power value, it indicates that the output power of the power strip is too high and the power strip is in an overload state. Therefore, if the output power of the power strip is not less than the third preset power value, the indicator light can be controlled to light up in a flashing mode to indicate to the user that the current power strip is in an overload state.
[0060] Understandably, if the power strip's output power is not less than the third preset power value, the indicator light can also be controlled to illuminate in other modes. The power strip's status corresponding to each lighting mode can be marked in the product manual to indicate the current usage status of the power strip to the user.
[0061] Understandably, if the power strip's output power is not less than the third preset power value, the protection function of the circuit protection module in the power strip will be triggered, and the indicator light will be controlled to flash in a flashing mode to ensure the safe use of the power strip.
[0062] It is understandable that the relationship between the first preset power value, the second preset power value, and the third preset power value can be that the first preset power value is less than the second preset power value, and the second preset power value is less than the third preset power value. In addition to corresponding to normal use, high-risk and overload states, the first preset power value, the second preset power value, and the third preset power value can also correspond to other different power strip states, which can be determined according to the application scenario of the power strip.
[0063] In some embodiments of this application, the intelligent light-sensing adjustable power strip includes a main control module with a first pin and a second pin. The main control module detects the live wire voltage of the power strip through the first pin and the neutral wire current of the power strip through the second pin. The main control module is also used to obtain the output power of the power strip based on the live wire voltage and the neutral wire current of the power strip.
[0064] refer to Figure 3 In this embodiment, the main control module can be a microcontroller U3 in the MCU circuit. The microcontroller U3 includes a first pin PB3 and a second pin PB2. The main control module can detect the live wire voltage of the power strip through the first pin PB3 and detect the neutral wire current of the power strip through the second pin PB2 to obtain the live wire voltage and neutral wire current data of the power strip. Then, based on the live wire voltage and neutral wire current data of the power strip, the output power of the power strip is calculated, so as to facilitate the control of the indicator light lighting mode according to the output power of the power strip.
[0065] In some embodiments of this application, the smart light-sensing adjustable power strip includes a light-sensing module comprising a photodiode and a first resistor connected in series. One end of the photodiode is connected to the first resistor, and the other end of the photodiode is connected to the main control module.
[0066] refer to Figure 3 In this embodiment, the light sensing module includes a photodiode D2 and a first resistor R3 connected in series. The main control module can be a microcontroller U3 in an MCU circuit. One end of the photodiode D2 is connected to the first resistor R3, and the other end of the photodiode D2 is connected to the fifteenth pin of the microcontroller U3. That is, the microcontroller U3 can read the voltage change of the photodiode D2 through the fifteenth pin to measure the ambient brightness. Specifically, when the ambient brightness changes, the resistance value of the photodiode D2 will also change, which will affect the voltage across the first voltage divider resistor R3 connected in series with it. The voltage change will be sampled by the microcontroller U3 and converted into a digital signal for processing and analysis.
[0067] In some embodiments of this application, the smart light-sensing adjustable power strip includes an indicator light comprising a light-emitting diode and a second resistor connected in series. One end of the light-emitting diode is connected to the second resistor, and the other end of the light-emitting diode is connected to the main control module.
[0068] refer to Figure 3 In this embodiment, the indicator light includes a light-emitting diode D1 connected in series with a second resistor R2. The main control module can be a microcontroller U3 in an MCU circuit. One end of the light-emitting diode D1 is connected to the second resistor R2, and the other end of the light-emitting diode D1 is connected to the sixteenth pin of the microcontroller U3. That is, the sixteenth pin of the microcontroller U3 is connected to the positive terminal of the light-emitting diode D1 through the second resistor R2. The light-emitting diode D1 and the second resistor R2 form a low-power LED driving scheme, as shown in the figure, with a current of about 3mA under a 3.3V power supply.
[0069] In one embodiment, the microcontroller U3 can control the brightness of the LED D1 by outputting a PWM (Pulse Width Modulation) signal through its sixteenth pin. The average voltage is adjusted by changing the time ratio of the PWM signal to high and low levels, thereby achieving continuous adjustment of the brightness of the LED D1. When the microcontroller U3 outputs a high level, current flows through the second resistor R2 and the LED D1, causing the LED D1 to light up; when the output is low, the current is interrupted, and the LED D1 turns off. By adjusting the duty cycle of the PWM signal, the brightness of the LED D1 can be precisely controlled.
[0070] In one embodiment, the power strip further includes a first capacitor C4 and a second capacitor C5, which together form the LDO post-stage filter circuit.
[0071] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
