[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] At present, the traditional indoor lighting solution is to maintain the ambient illumination value read by the sensor at a certain set value to adjust the brightness value of the lamp and save energy, but does not take into account the change of the desktop illumination value.

[0043] However, due to the difference in reflectivity between artificial light and natural light, the ambient illumination values ​​read by the sensor in different environments may be similar, but the actual illumination values ​​of the desktop may vary greatly, causing discomfort to the human eye.

[0044] Based on this, the embodiments of the present application provide a method, device, terminal and readable storage medium for controlling the brightness of a lamp, which can adjust the brightness value of the lamp as the intensity of light entering from outdoors changes, so that the illuminance value of the desktop can be maintained at the set illuminance value, while ensuring sufficient working lighting, saving energy and not causing discomfort to the human eye.

[0045] like Figure 1 , which is a schematic diagram of the implementation flow of a method for controlling the brightness value of a lamp provided in an embodiment of the present application, and which can be executed by a device for controlling the brightness value of a lamp configured on a terminal. Moreover, the terminal can be a smart home device such as a smart lamp.

[0046] Specifically, the method for controlling the brightness value of a lamp provided in the embodiment of the present application may include steps 101 to 104, which are described in detail as follows:

[0047] Step 101, obtaining a first preset model, a second preset model and a third preset model.

[0048] Among them, the above-mentioned first preset model is a relationship model between the lamp brightness value corresponding to the current space where the lamp is located in a darkroom environment and the desktop illuminance value, the second preset model is a relationship model between the lamp brightness value corresponding to the current space where the lamp is located in a darkroom environment and the illuminance value read by the sensor, and the third preset model is a relationship model between the sensor-read illuminance value corresponding to the current space where the lamp is located in a pure daylight environment and the desktop illuminance value.

[0049] Optionally, in some embodiments of the present application, Figure 2 As shown, the above-mentioned acquisition of the first preset model and the second preset model may include the following steps 201 to 204.

[0050] Step 201 : In a plurality of building spaces in a darkroom environment, first desktop illuminance value sample data corresponding to each output brightness value of a lamp and first illuminance value sample data read by a corresponding sensor are respectively collected.

[0051] For example, in each building space in a darkroom environment, when the brightness of the lamp is adjusted to a preset brightness value of 100%, the desktop illumination value read by the illuminance meter and the illumination value read by the sensor are used as the first desktop illumination value sample data corresponding to the 100% brightness value of the lamp, and the corresponding first illumination value sample data read by the sensor; when the brightness of the lamp is adjusted to a 50% brightness value, the desktop illumination value read by the illuminance meter and the illumination value read by the sensor are used as the first desktop illumination value sample data corresponding to the 50% brightness value of the lamp, and the first illumination value sample data read by the sensor; and so on, the first desktop illumination value sample data corresponding to each output brightness value of the lamp in multiple building spaces, and the corresponding first illumination value sample data read by the sensor are obtained.

[0052] Step 202 , linear fitting is performed on the first desktop illumination value sample data in each building space and the first illumination value sample data read by the sensor to obtain an initial first preset model and an initial second preset model.

[0053] Since linear fitting is performed using the first desktop illuminance value sample data corresponding to each output brightness value of lamps in different building spaces and the first illuminance value sample data read by the corresponding sensor, the structure of the model should be the same except that the parameters of the model may be different. Therefore, in the result of linear fitting, the initial first preset model with the largest proportion is the final initial first preset model, and the initial second preset model with the largest proportion is the final initial second preset model.

[0054] For example, in the linear fitting results of different building spaces, the initial first preset model Y=KX accounts for the largest proportion, so the initial first preset model can be set to Y=K1X, where X is the brightness value of the lamp, Y is the illuminance value of the desktop, and K1 is the model parameter.

[0055] For another example, in the linear fitting results of different building spaces, the initial second preset model M=KX accounts for the largest proportion, so the initial second preset model can also be set to M=K2X, where X is the brightness value of the lamp, M is the illumination value read by the sensor, and K2 is the model parameter.

[0056] Step 203, when the space where the lamp is currently located is in a darkroom environment, collect the desktop illumination value corresponding to the preset output brightness value of the lamp and the illumination value read by the corresponding sensor.

[0057] Step 204, input the desktop illuminance value corresponding to the preset output brightness value of the lamp into the initial first preset model, and input the illuminance value read by the sensor corresponding to the preset output brightness value of the lamp into the initial second preset model, obtain the model parameters of the first preset model and the second preset model, and obtain the first preset model and the second preset model.

[0058] In an embodiment of the present application, by collecting the desktop illuminance value corresponding to the preset output brightness value of the lamp and the corresponding illuminance value read by the sensor in a dark room environment, substituting them into the above-mentioned initial first preset model and the initial second preset model, the model parameters of the first preset model and the second preset model are obtained, and then the first preset model and the second preset model are obtained, thereby realizing the calibration of the brightness of the space where the lamp is currently located.

[0059] For example, the first preset model obtained is that the brightness value of the lamp in the darkroom environment is 5 times that of the desktop illumination value; the second preset model obtained is that the brightness value of the lamp in the darkroom environment is equal to the illumination value read by the sensor.

[0060] It should be noted that the preset output brightness value of the lamp in the above step 203 may be the maximum output brightness value of the lamp, or other output brightness values, and the present application does not impose any limitation on this.

[0061] The model acquisition method in this embodiment first establishes an initial first preset model and an initial second preset model, so that in actual use, it is only necessary to collect a set of desktop illuminance values ​​corresponding to the output brightness values ​​of the lamps in the current environment of the lamps, and the corresponding illuminance values ​​read by the sensor, so as to realize the calibration of the brightness values ​​in the current environment of the lamps, realize the establishment of the first preset model and the second preset model, which is conducive to the establishment of models adapted to different environments.

[0062] Optionally, in some embodiments of the present application, when obtaining the first preset model and the second preset model, it is also possible not to obtain the initial first preset model and the initial second preset model in advance, but to directly model the lamp in the space where the lamp is currently located to obtain the first preset model and the second preset model. Specifically, Figure 3 As shown, the following steps 301 to 302 may also be included.

[0063] Step 301 : when the space where the lamp is currently located is in a darkroom environment, collect second desktop illumination value sample data corresponding to each output brightness value of the lamp and second illumination value sample data read by the corresponding sensor.

[0064] For example, when the brightness of the lamp is adjusted to a preset brightness value of 100%, the desktop illuminance value read by the illuminance meter and the illuminance value read by the sensor are used as the second desktop illuminance value sample data corresponding to the 100% brightness value of the lamp, and the corresponding second illuminance value sample data read by the sensor; when the brightness of the lamp is adjusted to a 50% brightness value, the desktop illuminance value read by the illuminance meter and the illuminance value read by the sensor are used as the second desktop illuminance value sample data corresponding to the 50% brightness value of the lamp, and the corresponding second illuminance value sample data read by the sensor; and so on, the second desktop illuminance value sample data corresponding to each output brightness value of the lamp and the second illuminance value sample data read by the sensor are obtained.

[0065] Step 302 , linearly fitting the second desktop illumination value sample data and the second illumination value sample data read by the sensor respectively to obtain the first preset model and the second preset model.

[0066] In an embodiment of the present application, after obtaining the second desktop illuminance value sample data corresponding to each output brightness value of the lamp and the second illuminance value sample data read by the sensor, linear fitting is performed on the second desktop illuminance value sample data and the second illuminance value sample data read by the sensor respectively to obtain the first preset model and the second preset model.

[0067] For example, the first preset model obtained is that the brightness value of the lamp in the darkroom environment is 5 times that of the desktop illumination value; the second preset model obtained is that the brightness value of the lamp in the darkroom environment is equal to the illumination value read by the sensor.

[0068] Since the relationship between the illuminance value read by the sensor in a pure daylight environment and the illuminance value of the desktop is greatly affected by factors such as weather and season, they can be converted in a 1:1 relationship to ensure that the final adjusted desktop illuminance value is not too low, that is, the relationship model between the illuminance value read by the sensor in a pure daylight environment and the illuminance value of the desktop can be set to: the illuminance value read by the sensor in a pure daylight environment is equal to the illuminance value of the desktop.

[0069] Optionally, in some embodiments of the present application, the above-mentioned first preset model and the second preset model can also be pre-set to Y=K1X, and M=K2X; then, by collecting the desktop illuminance value sample data corresponding to each output brightness value of the lamp and the illuminance value sample data read by the sensor in a dark room environment, and substituting each output brightness value and the desktop illuminance value sample data corresponding to each output brightness value into Y=KX, the value k1 of K1 is obtained, and then the first preset model Y=k1X is obtained; and the output brightness value and the illuminance value sample data read by the sensor corresponding to each output brightness value are substituted into M=K2X, the value k2 of K2 is obtained, and then the second preset model M=k2X is obtained, so as to calibrate the brightness of the current space.

[0070] Among them, X is the brightness value of the lamp, Y is the illuminance value of the desktop, and M is the illuminance value read by the sensor.

[0071] Step 102, obtaining the ambient illumination value currently read by the sensor and the current output brightness value of the lamp.

[0072] In the embodiment of the present application, the sensor may be located on the lamp, or at a preset position in the space where the lamp is currently located, and the position is the same as the position of the sensor when acquiring the second preset model and the third preset model.

[0073] The ambient illuminance value currently read by the sensor may be an illuminance value generated by a lamp and an illuminance value generated by daylight collected by the sensor in real time.

[0074] Optionally, the current output brightness value of the above-mentioned lamp can be calculated according to the current output power of the lamp.

[0075] Step 103, calculating the current desktop illumination value according to the ambient illumination value, the current output brightness value of the lamp, and the first preset model, the second preset model and the third preset model.

[0076] Optional, such as Figure 4 As shown, in some embodiments of the present application, when the current desktop illumination value is calculated according to the ambient illumination value, the current output brightness value of the lamp, and the first preset model, the second preset model and the third preset model, the following steps 401 to 404 can be used to implement it.

[0077] Step 401 : According to the current output brightness value x1 of the lamp and the first preset model, the desktop illumination value y1 corresponding to the current output brightness value of the lamp is calculated.

[0078] For example, the current output brightness value of the lamp is x1=100, and the first preset model is that the brightness value of the lamp that is 5 times that of the dark room environment is equal to the desktop illumination value, that is, Y1=5*X1. Then, substitute the current output brightness value of the lamp x1=100 into Y1=5*X1, and you can get the desktop illumination value y1=500 corresponding to the current output brightness value of the lamp.

[0079] Step 402: According to the current output brightness value x1 of the lamp and the second preset model, the sensor-read illumination value y2 corresponding to the current output brightness value of the lamp is calculated.

[0080] Based on the above example, if the current output brightness value of the lamp is x1=100, and the second preset model is that the brightness value of the lamp in the dark room is equal to the illuminance value read by the sensor, then the sensor read illuminance value y2=100 corresponding to the current output brightness value of the lamp.

[0081] Step 403, according to the difference between the ambient illuminance value y3 currently read by the sensor and the illuminance value y2 read by the sensor corresponding to the current output brightness value of the lamp, and the third preset model, calculate the desktop illuminance value y4 corresponding to the current daylight.

[0082] Based on the above example, if the ambient illuminance value y3 currently read by the sensor is 350, then the difference between the ambient illuminance value y3 currently read by the sensor and the sensor-read illuminance value y2 corresponding to the current output brightness value of the lamp is 350-100=250, which is the illuminance value read by the sensor provided by daylight; then when the third preset model is: the illuminance value read by the sensor in a pure daylight environment is equal to the desktop illuminance value, then y4=250.

[0083] Step 404 , according to the desktop illumination value y1 corresponding to the current output brightness value of the lamp and the desktop illumination value y4 corresponding to the current daylight, the current desktop illumination value y5=y1+y4 is calculated.

[0084] Based on the above example, we can obtain y5=500+250=750.

[0085] Step 104, calculating a target brightness value of the lamp according to the difference between the current desktop illumination value and the preset desktop illumination value and the first preset model, and controlling the brightness value output by the lamp to be equal to the target brightness value.

[0086] For example, the preset desktop illumination value is 500. Based on the above example, the difference between the current desktop illumination value and the preset desktop illumination value is 750-500=250, and the target brightness value of the lamp is 250 / 5=50.

[0087] It should be noted that the unit of the illumination value in the above example is lux, and the unit of the above brightness value is candela / square meter (cd / m2).

[0088] In the embodiment of the present application, by obtaining the relationship model between the brightness value of the lamp corresponding to the space where the lamp is currently located in a darkroom environment and the illuminance value of the desktop, the relationship model between the brightness value of the lamp corresponding to the space where the lamp is currently located in a darkroom environment and the illuminance value read by the sensor, and the relationship model between the illuminance value read by the sensor and the illuminance value of the desktop in a pure daylight environment, that is, the first preset model, the second preset model and the third preset model, and based on the ambient illuminance value currently read by the sensor and the current output brightness value of the lamp, the current desktop illuminance value is calculated using the first preset model, the second preset model and the third preset model, and then the target brightness value of the lamp is calculated according to the difference between the current desktop illuminance value and the preset desktop illuminance value, and then the brightness value output by the lamp is controlled to be equal to the target brightness value, so that the desktop illuminance value can be maintained at the preset desktop illuminance value as the intensity of light entering from the outdoors changes by adjusting the brightness value of the lamp, instead of maintaining the illuminance value read by the sensor at the preset illuminance value, thereby saving energy while ensuring sufficient working lighting, and without causing discomfort to the human eye.
