Therefore, it is particularly important to develop a system and method that can automatically adjust the LED light flux according to the opening and closing angle of the refrigerator door.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in the description of the present invention, the meaning of "multiple" and "several" is at least two, for example two, three, etc., unless otherwise clearly and specifically defined.

[0030] Example 1

[0031] See also Figure 2 As shown, the present invention is a control method for regulating the light flux of a refrigerator LED, comprising the following steps:

[0032] S1. Use the angle sensor 10 to detect the opening and closing angle α of the refrigerator door in real time, and convert the α angle signal into an electrical signal for output; the electrical signal converted by the angle sensor 10 can be output in a wired or wireless manner.

[0033] In this step, the angle sensor 10 is precisely installed on the refrigerator door for use. The angle sensor 10 is usually installed near the rotation axis connecting the refrigerator door and the cabinet, so as to ensure that the angle sensor 10 can accurately measure the rotation angle of the door.

[0034] It should be understood that, when the angle sensor 10 converts the α angle signal into an electrical signal, the angle signal data may be processed, including filtering, amplification and other steps, to improve the accuracy and reliability of the data.

[0035] S2. The electrical signal output by the angle sensor 10 is fed back to the electrical control system 20. The electrical control system 20 receives the electrical signal and performs analysis and processing to generate a resistance adjustment instruction corresponding to the opening angle of the refrigerator door.

[0036] In this step, the steps of the electrical control system 20 receiving the electrical signal and analyzing and processing it are as follows: the electrical control system 20 includes a signal processing module 40 for receiving the electrical signal output by the angle sensor 10, and the signal processing module 40 analyzes the received electrical signal to extract information related to the opening angle of the refrigerator door. According to the relevant information extracted through the analysis, the signal processing module 40 further demodulates and synthesizes the electrical signal to more comprehensively reflect the opening and closing status of the refrigerator door.

[0037] It should be understood that during the electrical signal analysis process performed by the signal processing module 40, the time domain signal can be converted into a frequency domain signal through Fourier transform so as to more intuitively observe the frequency components and distribution of the electrical signal, so as to extract information related to the opening angle of the refrigerator door; during the electrical signal processing process performed by the signal processing module 40, demodulation is the process of restoring the modulated signal to the original signal. For the modulated signal output by the angle sensor 10, demodulation can restore its correspondence with the opening angle, and signal synthesis may involve combining multiple signals into a composite signal so as to more comprehensively reflect the opening and closing status of the refrigerator door.

[0038] In this step, the electrical control system 20 generates a resistance adjustment instruction corresponding to the refrigerator door opening angle as follows: based on the result signal of the analysis and processing of the electrical signal by the signal processing module 40, the result signal is compared with a preset refrigerator door opening angle threshold or standard to determine the direction and amplitude of the resistance adjustment, so as to generate a resistance adjustment instruction corresponding to the refrigerator door opening angle.

[0039] It should be understood that in the process of determining the direction and amplitude of resistance adjustment, when the door opening angle exceeds a certain threshold, an instruction to increase resistance can be generated; when the door opening angle is less than a certain threshold, an instruction to reduce resistance can be generated.

[0040] S3. According to the generated resistance adjustment instruction, the electrical control system 20 dynamically adjusts the driving resistance of the LED lamp module 30. The driving resistance drives the variable current provided by the LED lamp module 30 to achieve intelligent adjustment of the luminous flux of the LED lamp module 30.

[0041] In this step, the electrical control system 20 dynamically adjusts the driving resistance of the LED lamp module 30 as follows: the driving resistance adjustment module 50 included in the electrical control system 20 is used to receive the generated resistance adjustment instruction; wherein, dynamically adjusting the driving resistance of the LED lamp module 30 includes increasing or decreasing the driving resistance.

[0042] In this step, the step of driving the variable current provided by the driving resistor to the LED lamp module 30 is as follows: when the power supply voltage of the LED lamp module 30 remains unchanged, as the resistance value of the driving resistor is adjusted, the operating current of the LED lamp module 30 will also be adjusted accordingly, and the luminous flux of the LED lamp module 30 is proportional to its operating current, so as to realize intelligent adjustment of the luminous flux of the LED lamp module 30.

[0043] It needs to be understood that the driving resistance of the LED lamp is dynamically adjusted according to the resistance adjustment instruction, which is specifically divided into two dynamic adjustment branches, corresponding to the situations where the door opening angle is small and the door opening angle is large respectively; for example, when the door opening angle is small, the driving resistance can be increased, thereby reducing the current of the LED lamp and reducing the light flux; when the door opening angle is large, Mingkeyuan reduces the driving resistance, thereby increasing the current of the LED lamp and increasing the light flux.

[0044] It should be understood that the control method of the present application is used continuously during the operation of the refrigerator, and adjusts the light flux in real time to adapt to changes in the opening and closing angle of the refrigerator door.

[0045] By adopting the control method of the present application, it is possible to realize intelligent adjustment of LED light flux, avoid unnecessary energy waste, improve the energy efficiency ratio of the refrigerator, and thus achieve the function of energy saving and consumption reduction; and at different refrigerator door opening angles, the LED light can maintain an appropriate brightness, providing users with a more comfortable environment for taking items, thereby achieving the function of improving user experience; in addition, the present application realizes intelligent control of the refrigerator lighting system, improves the overall intelligence level of household appliances, and thus achieves the function of intelligent control.

The intelligent control operation of this system is convenient and can be applied in the scenario of intelligent regulation of LED light flux.

[0049] See also Figure 1 As shown, the present invention also provides an intelligent system for regulating the light flux of a refrigerator LED, including an angle sensor 10, an electrical control system 20 and an LED light module 30. The angle sensor 10 is installed on the refrigerator door. The angle sensor 10 is used to monitor the opening and closing angle of the refrigerator door in real time, and convert the angle signal into an electrical signal for output. The electrical control system 20 includes a signal processing module 40 and a drive resistance adjustment module 50. The signal processing module 40 is used to receive the electrical signal output by the angle sensor 10, and generate a resistance adjustment instruction corresponding to the opening angle of the refrigerator door; the drive resistance adjustment module 50 dynamically adjusts the drive resistance of the LED light module 30 according to the resistance adjustment instruction output by the signal processing module 40. The LED light module 30 is driven by the variable current provided by the drive resistance adjustment module 50, thereby realizing intelligent adjustment of the light flux of the LED light module 30.

[0050] By adopting the intelligent system of the present application, it is possible to realize intelligent adjustment of LED light flux, avoid unnecessary energy waste, improve the energy efficiency ratio of the refrigerator, and thus achieve the function of energy saving and consumption reduction; and at different refrigerator door opening angles, the LED light can maintain an appropriate brightness, providing users with a more comfortable environment for taking items, thereby achieving the function of improving user experience; in addition, the present application realizes intelligent control of the refrigerator lighting system, improves the overall intelligence level of household appliances, and thus achieves the function of intelligent control.

[0051] It should be understood that the electrical control system 20 in the present application also includes a central processing unit, which is used to coordinate the operation of the angle sensor 10, the signal processing module 40, the drive resistance adjustment module 50 and the LED lamp module 30, and is used to implement the control method steps for regulating the light flux of the refrigerator LED lamp as in Example 1 during execution.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
