[0002] As people's living standards improve, in order to meet their pursuit of intelligent lighting and green energy-saving living, they are spending more and more time working, studying, and living in indoor lighting environments, which puts forward higher requirements for light quality. Especially in scenarios such as school classrooms, classroom illuminance is uneven, corner lights are dim, and the illuminance of desks and blackboards is not up to standard, which can easily lead to students' eye fatigue. Glare is serious and affects students' concentration. Therefore, the need for constant illuminance lighting environments is particularly urgent. During the development process and after the completion of development, it is necessary to conduct a lot of repeated debugging of the stability and robustness of constant illuminance functions under different environmental conditions, and evaluate whether the function meets the standards through the feedback data obtained. Summary of the Invention

[0006] Real-time acquisition: Acquires actual ambient illuminance values ​​representing real-time ambient illuminance, and monitors real-time device luminance values ​​representing real-time device brightness;

[0007] Comparison and judgment: Compare the actual ambient illuminance value with the constant illuminance value, and at the same time compare the initial brightness value of the device with the real-time brightness value of the device. Adjust the real-time brightness value of the device according to the two comparison results so that the actual ambient illuminance value is close to the constant illuminance value.

[0008] Preferably, the comparison and judgment step further includes judging the actual ambient illuminance value, judging whether the actual ambient illuminance value is less than 0. If the actual ambient illuminance value is less than 0, an error result is output and the judgment ends; if the actual ambient illuminance value is not less than 0, then it is judged whether the actual ambient illuminance value is equal to 0.

[0009] Preferably, it is determined whether the actual ambient illuminance value is equal to 0. If the actual ambient illuminance value is equal to 0, then the current actual ambient illuminance value is the minimum value, and the determination ends. If the actual ambient illuminance value is not equal to 0, then the actual ambient illuminance value is compared with the constant illuminance value, and the initial brightness value of the device is compared with the real-time brightness value of the device.

[0010] Preferably, if the actual ambient illuminance value is greater than the constant illuminance value and the real-time brightness value of the device is less than the initial brightness value of the device, the device is dimmed to reduce the real-time brightness value of the device; if the actual ambient illuminance value is greater than the constant illuminance value and the real-time brightness value of the device is greater than the initial brightness value of the device, a result indicating that the constant illuminance function is malfunctioning is output.

[0011] If the actual ambient illuminance is less than the constant illuminance, and the real-time brightness of the device is greater than the initial brightness of the device, the device will be dimmed to increase the real-time brightness of the device; if the actual ambient illuminance is less than the constant illuminance, and the real-time brightness of the device is less than the initial brightness of the device, the constant illuminance function will be output as an abnormal operation result.

[0012] Repeatedly adjust the actual ambient illuminance value.

[0013] Preferably, in the real-time acquisition step, the actual ambient illuminance value is acquired through the sensing module of the host computer, the voltage signal of the device is acquired through the circuit module of the host computer, and the voltage signal is converted into the real-time brightness value of the device.

[0014] A constant illuminance adjustment device includes a housing, a light sensing module, an illuminance meter, a control unit, a lamp, a drive module, and a light shield;

[0015] The light sensing module and the illuminance meter are disposed on the upper surface of the housing, and the lamp, the control unit and the drive module are disposed inside the housing; the control unit is electrically connected to the light sensing module, the illuminance meter, the lamp and the drive module;

By setting the initial brightness value and the constant illuminance value, during use, the actual ambient illuminance value is collected and compared with the constant illuminance value. The brightness of the device is adjusted in real time to change the ambient illuminance and keep it within a stable range, thus enabling the device to enter a stable lighting state and providing a comfortable experience for the user.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of this invention, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0028] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0029] See Figures 1 to 3 As shown, a constant illuminance adjustment method includes the following steps:

[0030] Initialization settings: Set the initial brightness value of the device, representing the device's brightness; set the constant illuminance value, representing the desired ambient illuminance.

[0031] Real-time acquisition: Acquires actual ambient illuminance values ​​representing real-time ambient illuminance, and monitors real-time device luminance values ​​representing real-time device brightness;

[0032] Comparison and judgment: Compare the actual ambient illuminance value with the constant illuminance value, and at the same time compare the initial brightness value of the device with the real-time brightness value of the device. Adjust the real-time brightness value of the device according to the two comparison results so that the actual ambient illuminance value is close to the constant illuminance value.

[0033] In this invention, the actual ambient illuminance value refers to the daily illuminance value, the constant illuminance value refers to the manually set target illuminance value, the real-time brightness value of the device refers to the brightness of the lamps or other lighting equipment, and the initial brightness value of the device refers to the manually set initial brightness of the lamps or other lighting equipment. By setting the initial brightness value and the constant illuminance value, during use, the actual ambient illuminance value is collected and compared with the constant illuminance value. The brightness of the device is adjusted in real time to change the ambient illuminance and keep it within a stable range, that is, the device enters a stable lighting state, providing users with a comfortable experience.

[0034] This invention improves work efficiency and adjustment accuracy by adjusting the illumination of the equipment in real time, reduces labor costs, and provides an efficient testing method for research and development debugging.

[0035] Preferably, the comparison and judgment step further includes judging the actual ambient illuminance value, judging whether the actual ambient illuminance value is less than 0. If the actual ambient illuminance value is less than 0, an error result is output and the judgment ends; if the actual ambient illuminance value is not less than 0, then it is judged whether the actual ambient illuminance value is equal to 0.

[0036] When judging the actual ambient illuminance value, since the actual ambient illuminance value cannot be negative, if the collected actual ambient illuminance value is less than 0, the collection result is judged to be incorrect.

[0037] Preferably, it is determined whether the actual ambient illuminance value is equal to 0. If the actual ambient illuminance value is equal to 0, then the current actual ambient illuminance value is the minimum value, and the determination ends. If the actual ambient illuminance value is not equal to 0, then the actual ambient illuminance value is compared with the constant illuminance value, and the initial brightness value of the device is compared with the real-time brightness value of the device.

[0038] When the actual ambient illuminance value is 0, the actual ambient illuminance value is at its minimum, meaning the environment is in darkness, and the judgment ends.

[0039] Preferably, if the actual ambient illuminance value is greater than the constant illuminance value and the real-time brightness value of the device is less than the initial brightness value of the device, the device is dimmed to reduce the real-time brightness value of the device; if the actual ambient illuminance value is greater than the constant illuminance value and the real-time brightness value of the device is greater than the initial brightness value of the device, a result indicating that the constant illuminance function is malfunctioning is output.

[0040] If the actual ambient illuminance is less than the constant illuminance, and the real-time brightness of the device is greater than the initial brightness of the device, the device will be dimmed to increase the real-time brightness of the device; if the actual ambient illuminance is less than the constant illuminance, and the real-time brightness of the device is less than the initial brightness of the device, the constant illuminance function will be output as an abnormal operation result.

[0041] Repeatedly adjust the actual ambient illuminance value.

[0042] When the actual ambient illuminance is greater than the constant illuminance, and the device's real-time brightness is less than its initial brightness, the device is in dimming mode, and the brightness decreases. Alternatively, when the actual ambient illuminance is less than the constant illuminance, and the device's real-time brightness is greater than its initial brightness, the device dims, and the brightness changes. Only in these two situations is the constant illuminance function functioning correctly. Data collection continues, and the device is repeatedly tested and verified to stabilize the real-time illuminance output. If other situations occur, such as the device not brightening or the dimming state being reversed, it indicates that the constant illuminance function is malfunctioning, resulting in an abnormal output. The device is then repeatedly tested using the actual ambient illuminance value. After one round of analysis, the assessment concludes.

[0043] Preferably, in the real-time acquisition step, the actual ambient illuminance value is acquired through the sensing module of the host computer, the voltage signal of the device is acquired through the circuit module of the host computer, and the voltage signal is converted into the real-time brightness value of the device.

[0044] In this invention, the host computer includes a smart terminal device, on which a corresponding APP program is set. The APP program sets the initial brightness value and constant illuminance value of the device. The host computer reads the ambient illuminance value and the real-time brightness value of the device from the sensor via its serial port function, and stores the constant illuminance value, the real-time brightness value, and the initial brightness value.

[0045] For example: (1) Set a constant illuminance value, assuming it is 250 lux (lux is a unit of illuminance);

[0046] (2) The host computer's optical sensor collects the actual ambient illuminance value in real time;

[0047] (3) Compare the constant illuminance value with the actual ambient illuminance value:

[0048] ① If the absolute value of the difference between the two values ​​does not exceed 10 lux, then there is no need to adjust the device brightness;

[0049] ② When the absolute value of the difference between the two values ​​exceeds 10 lux, the device will automatically adjust the brightness to change the actual ambient illuminance and continue to cycle until the absolute value of the difference between the two values ​​does not exceed 10 lux, reaching a relatively stable state. At this time, the brightness of the device will remain at a certain level and will no longer change.

[0050] (4) By artificially changing the ambient brightness, the original stable state is broken, and (2) and (3) are repeated until the next stable state is reached.

[0051] (5) During the actual test, the constant illuminance calibration value was 250 lux. After the overall illuminance tended to stabilize, the actual ambient illuminance value collected fluctuated in the range of 245 lux to 255 lux.

[0052] A constant illuminance adjustment device includes a housing 1, a light sensing module 2, an illuminance meter 3, a control unit 4, a lamp 5, a drive module 6, and a light shield 7.

[0053] The light sensing module 2 and the illuminance meter 3 are disposed on the upper surface of the housing 1, and the lamp 5, the control unit 4 and the drive module 6 are disposed inside the housing 1; the control unit 4 is electrically connected to the light sensing module 2, the illuminance meter 3, the lamp 5 and the drive module 6.

[0054] The light-shielding plate 7 is disposed on the side wall of the housing 1, and the light-shielding plate 7 is located on the periphery of the lamp 5;

[0055] The output end of the drive module 6 is connected to the light-shielding plate 7 and is used to drive the light-shielding plate 7 to move.

[0056] This invention collects ambient brightness through a light sensor module 2 and an illuminance meter 3, and performs logical judgment and comparison through a control unit 4. Based on the comparison results of the collected actual ambient illuminance, constant illuminance value and real-time brightness value of the device, the angle of the light shield 7 is adjusted in real time through a drive module 6 to change the ratio of light shielding and light transmission of the lamp, thereby achieving the purpose of adjusting the ambient brightness and maintaining a stable illuminance environment.

[0057] This invention enables several functions, including automatic adjustment of ambient brightness. Establishing a functional testing environment to simulate the actual application environment of a product has always been a challenging process. The simulation function in this device can reduce workload and improve efficiency. The control unit controls the drive module to move the light-shielding plate, adjusting the ratio of light blocking to light transmission, thereby adjusting the natural brightness of the testing environment.

[0058] Automatically shuts off ambient brightness adjustment function: When the constant illuminance function test is completed, the device itself will automatically close the light shield, returning it to its initial state.

[0059] Automatically activates the ambient brightness adjustment function: After installing the device under test and enabling constant illuminance on the APP, the device itself automatically opens the light shield and enters the working environment state to prepare for adjusting the ambient brightness.

[0060] The constant illuminance automated testing function: The control unit controls the drive module to move the light-shielding plate, adjusting the ratio of light blocking to light transmission, thereby controlling the brightness of the simulated environment. The host computer obtains the ambient illuminance value, constant illuminance value, and real-time brightness value of the equipment in real time. The analysis is used to determine whether the constant illuminance function is normal and to enable the constant illuminance to adapt to environmental changes, thus achieving automated constant illuminance testing. It also verifies the intelligence and robustness of the constant illuminance.

[0061] Automatic illuminance value acquisition function: The system acquires the actual ambient illuminance value and the constant illuminance value set in calibration settings in real time via a host computer, and then determines whether the constant illuminance value is within the range. When the actual ambient illuminance value is within the range of the constant illuminance value, the device will not need to adjust the dimming; when the actual ambient illuminance value is not within the range of the constant illuminance value, the device needs to adjust the dimming, record the data in real time, and display the results.

[0062] Preferably, the side wall of the housing 1 is provided with a plurality of light-transmitting holes 8, and the driving module 6 drives the light-shielding plate 7 to move and cover the light-transmitting holes 8.

[0063] The light-shielding plate 7 is moved by the drive module 6, which can be a motor or cylinder or other drive component. By changing the position of the light-transmitting hole 8 covered by the light-shielding plate 7, the lighting intensity of the device is changed, thereby adjusting the brightness of the environment.

[0064] It also includes a host computer, which is communicatively connected to the control unit 4.
