[0047] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0048] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0049] In conjunction with the accompanying drawings, the control method of the lighting device, the control device of the lighting device, the electronic device and the readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0050] The control method of the lighting device may be applied to a terminal, and may be specifically executed by hardware or software in the terminal.

[0051] The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad). It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad).

[0052] In the following various embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse and a joystick.

[0053] The control method of the lighting device provided in the embodiment of the present application may be executed by a lighting control system or an electronic device, or a functional module or functional entity in the lighting control system or the electronic device that can implement the control method of the lighting device. The electronic devices mentioned in the embodiment of the present application include but are not limited to mobile phones, tablet computers, computers, cameras, and wearable devices. The control method of the lighting device provided in the embodiment of the present application is described below using the electronic device as an example of the execution subject.

[0054] like Figure 1 As shown, the control method of the lighting device includes: step 110, step 120 and step 130.

[0055] Step 110: Obtain at least one of the ambient light intensity and the ambient color temperature in the environment where the lighting device is located;

[0056] In this step, the lighting device may include indoor lighting devices, automotive lighting devices, other lighting devices, and the like.

[0057] For example, the lighting device may include a wall lamp, a table lamp, or a ceiling light in a car.

[0058] The ambient light intensity and ambient color temperature of the environment in which the lighting device is located can be acquired based on the ambient light sensor.

[0059] The ambient light sensor may be installed near the lighting device or integrated inside the lighting device, and the photosensitive module of the ambient light sensor is in direct contact with the external environment.

[0060] Ambient light intensity is used to characterize the brightness or intensity of light in an environment and is usually measured in lux (Lx).

[0061] Ambient color temperature is used to characterize the color of light, such as warm light or cold light, and is usually expressed in Kelvin (K).

[0062] The environment in which the lighting device is located may include sunny days, cloudy days, mornings, afternoons, and evenings, etc.

[0063] Step 120: acquiring a target color temperature corresponding to the lighting device based on at least one of the ambient light intensity and the ambient color temperature and at least one of the first light intensity and the first color temperature input by a user;

[0064] In this step, the first light intensity and the first color temperature are used to characterize the user's light demand.

[0065] The first illumination intensity is a desired illumination intensity set by a user.

[0066] The first color temperature is a desired color temperature set by a user.

[0067] In some embodiments, a first input from a user may be received;

[0068] In response to the first input, a target color temperature is obtained.

[0069] In this embodiment, the first input is used to input at least one of a first light intensity and a first color temperature.

[0070] The first input may be in at least one of the following ways:

[0071] First, the first input may be a touch operation, including but not limited to a click operation, a slide operation, and a press operation.

[0072] In this implementation, receiving the first input from the user may be receiving a touch operation of the user in the display area of ​​the terminal display screen.

[0073] In order to reduce the user error rate, the effective area of ​​the first input can be limited to a specific area, such as the upper middle area of ​​the input interface of the lighting device; or when the interface of the input preference setting is displayed, the target control is displayed on the current interface, and the first input can be achieved by touching the target control; or the first input can be set to a continuous multiple tapping operation on the display area within a target time interval.

[0074] Secondly, the first input may be a physical key input.

[0075] In this embodiment, the terminal body is provided with physical buttons corresponding to the preferred light intensity and the preferred color temperature. Receiving the user's first input can be receiving the operation of the user pressing the corresponding physical button; the first input can also be a combined operation of pressing multiple physical buttons at the same time.

[0076] Third, the first input may be voice input.

[0077] In this implementation, when the terminal receives a voice message such as "adjust the color temperature of the desk lamp to warm light", it can trigger the display of an interface for adjusting the color temperature of the lighting device to warm light.

[0078] Of course, in other embodiments, the first input may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs and is not limited in this embodiment of the present application.

[0079] The target color temperature is the optimal color temperature that the lighting device should achieve, calculated based on environmental conditions and user needs.

[0080] The ambient light intensity, the ambient color temperature, the first light intensity and the first color temperature may be weighted based on the weights corresponding to the ambient light intensity, the ambient color temperature, the first light intensity and the first color temperature to obtain the target color temperature.

[0081] Alternatively, a lookup table containing target color temperature values ​​under different combinations of ambient color temperatures, user color temperature preferences, ambient light intensities, and user light intensity preferences may be prepared in advance.

[0082] In actual implementation, the corresponding target color temperature value can be found in the lookup table according to the current environment and user preference.

[0083] When the resolution of the lookup table is not enough or a more flexible calculation method is required, the target color temperature can also be calculated using interpolation.

[0084] For example, interpolation calculations may be performed based on known data points to obtain a more accurate target color temperature value.

[0085] Step 130: Control the lighting device based on the target color temperature.

[0086] In this step, the color temperature setting of the lighting device can be adjusted to ensure that the light it emits matches the target color temperature.

[0087] For example, the lighting output of a lighting device can be changed by adjusting parameters of the lighting device (such as color temperature or brightness).

[0088] According to the control method of the lighting device provided in the embodiment of the present application, by collecting the environmental condition parameters of the current environment, combined with the user's preferences and needs in the current environment, the target color temperature corresponding to the lighting device is calculated, and the lighting device is controlled based on the target color temperature. The color temperature of the lighting device can be automatically adjusted according to the environmental conditions without the need for repeated manual adjustments. The operation is convenient and the lighting effect can be coordinated with the ambient light in different time periods or under different weather conditions, thereby meeting the user's needs for a dynamic lighting environment and improving the user's usage experience.

[0089] In some embodiments, step 130 may include:

[0090] Based on the target color temperature, the brightness of each light strip is calculated;

[0091] Based on the brightness of each light strip, the color temperature of the lighting device is controlled.

[0092] In this embodiment, the lighting device may include at least one light strip.

[0093] The brightness of each light strip can be adjusted separately.

[0094] Each light strip has a corresponding color temperature range and brightness range.

[0095] The color temperature of the lighting device can be adjusted by adjusting the brightness value of the light strip.

[0096] The brightness value corresponding to the target color temperature can be found in a preset color temperature-brightness mapping table.

[0097] The brightness of different light strips is combined to achieve the target color temperature of the lighting device.

[0098] For example, the lighting device includes multiple light strips with different color temperatures (such as warm light strips and cold light strips). When the target color temperature is warmer, the brightness of the warm light strip can be increased; when the target color temperature is colder, the brightness of the cold light strip can be increased. At the same time, the mutual influence between the light strips can be considered to ensure the accuracy and consistency of the overall color temperature.

[0099] According to the brightness value of each light strip, the actual brightness output of each light strip in the lighting device can be adjusted to adjust the color temperature of the lighting device.

[0100] For example, the calculated brightness values ​​corresponding to each light strip can be converted into a control signal (such as a PWM (Pulse Width Modulation) signal or an analog voltage, etc.), and then sent to a controller or driver of each light strip. The controller or driver can adjust the brightness output of the light strip according to the received control signal to adjust the color temperature of the lighting device.

[0101] In the actual implementation process, the lighting system can recalculate and adjust the brightness value of each light strip in real time according to changes in ambient lighting conditions or changes in user needs to maintain the stability and accuracy of the color temperature of the lighting device.

[0102] According to the control method of the lighting device provided in the embodiment of the present application, the brightness of each light strip is calculated based on the target color temperature, and the lighting device is controlled based on the brightness of each light strip. This can intelligently adapt to different environments and user needs, providing a more comfortable and personalized lighting experience.

[0103] like Figure 2As shown, in some embodiments, based on the target color temperature, the brightness corresponding to each light strip is calculated, including:

[0104] Based on the target color temperature, a first output ratio corresponding to the warm color light strip and a second output ratio corresponding to the cool color light strip are calculated;

[0105] Based on the first output ratio, the brightness of the warm-color light strip is determined; based on the second output ratio, the brightness of the cool-color light strip is determined.

[0106] In this embodiment, the at least one light strip includes a warm-color light strip and a cool-color light strip.

[0107] The warm-color light strip may include one or more light strips, and the cool-color light strip may include one or more light strips.

[0108] In order to control the color temperature of the lighting device to reach the target color temperature, it can be calculated what proportion of light the warm-color light strip and the cool-color light strip should output respectively.

[0109] For example, the target color temperature is T, the color temperature range of the warm color light strip is Tw to Th (where Tw is warmer, Th is cooler than Tw but still belongs to the warm color system), and the color temperature range of the cool color light strip is Tc to Tb (where Tc is cooler, Tb is warmer than Tc but still belongs to the cool color system).

[0110] According to the relationship between T and Tw, Th, Tc, and Tb, the first output ratio P1 of the warm color light strip and the second output ratio P2 of the cool color light strip can be calculated by interpolation, table lookup or other methods.

[0111] The sum of the first output ratio and the second output ratio is 1. When the brightness of one light strip increases, the brightness of the other light strip must be reduced accordingly to keep the total brightness unchanged or fluctuate within a smaller range, while achieving color temperature adjustment.

[0112] Assuming that the maximum brightness of the warm color light strip is Lw_max and the maximum brightness of the cold color light strip is Lc_max, the actual brightness Lw of the warm color light strip can be calculated by multiplying P1 by Lw_max (i.e., Lw=P1*Lw_max). Similarly, the actual brightness Lc of the cold color light strip can be calculated by multiplying P2 by Lc_max (i.e., Lc=P2*Lc_max).

[0113] In actual implementation, the lighting device (such as an LED lamp) includes two light strips, namely a warm color light strip A (low color temperature) and a cool color light strip B (high color temperature). The two light strips can generate various color temperatures from warm to cool by mixing different brightness ratios.

[0114] The color temperature of the lighting device can be adjusted using PWM technology, where PWM is a method of adjusting the average power (and thus controlling the brightness) by changing the duty cycle of a pulse signal (ie, the ratio of pulse width to period).

[0115] The PWM outputs of the two light strips can be controlled by ambient light perception, and PWMA+PWMB=1, where PWMA and PWMB represent the PWM duty cycles of the warm-color light strip A and the cool-color light strip B, respectively.

[0116] According to the control method of the lighting device provided in the embodiment of the present application, the brightness ratio of the warm-color light strips and the cool-color light strips can be intelligently adjusted through the target color temperature requirements, thereby achieving continuous adjustment of the color temperature. At the same time, the lighting system can adapt to environmental changes more intelligently and provide a more comfortable and personalized lighting experience.

[0117] Continue to refer Figure 2 In some embodiments, step 130 may include:

[0118] When the target color temperature is not within the color temperature adjustment range, the lighting device is controlled to keep the current color temperature unchanged.

[0119] In this embodiment, the lighting device may have a preset color temperature adjustment range, which is usually determined based on the hardware characteristics of the lighting device itself (such as the color temperature range of the LED light source and the accuracy of the color temperature adjustment module, etc.).

[0120] It can be determined whether the target color temperature falls within a preset color temperature adjustment range. For example, the target color temperature value can be compared with the upper and lower limits of the color temperature adjustment range. If the target color temperature is not within the adjustment range, it can be determined not to change the current color temperature of the lighting device according to a preset strategy.

[0121] That is, the lighting device will continue to operate at the current color temperature until the target color temperature obtained by the next update is within the color temperature adjustment range, or the system receives other instructions to change the color temperature.

[0122] In some embodiments, before controlling the lighting device to maintain the current color temperature unchanged, the method may further include: outputting a prompt message, where the prompt message is used to prompt the user that the target color temperature exceeds the adjustment range.

[0123] In this embodiment, the prompt information may include an interface prompt or a sound warning, etc.

[0124] In some embodiments, when the target color temperature is not within the color temperature adjustment range, the color temperature of the lighting device may be adjusted to a color temperature value that is within the color temperature adjustment range and closest to the target color temperature.

[0125] In some embodiments, step 120 may include:

[0126] Based on a first weight corresponding to the ambient light intensity, a second weight corresponding to the ambient color temperature, a third weight corresponding to the first light intensity, and a fourth weight corresponding to the first color temperature, a weighted summation process is performed on the ambient light intensity, the ambient color temperature, the first light intensity, and the first color temperature to obtain a target color temperature corresponding to the lighting device.

[0127] In this embodiment, the importance of each parameter can be balanced by adjusting the weight coefficient. The first weight, the second weight, the third weight and the fourth weight can be adjusted and customized based on the actual application scenario and user preferences, and this application does not limit this.

[0128] For example, when the first color temperature (ie, the user's preferred color temperature) is more important, the fourth weight may be set to a larger value; if it is desired to reduce the color temperature when the ambient light intensity is high, the first weight may be set to a negative value.

[0129] For example, the target color temperature corresponding to the lighting device can be calculated according to the formula:

[0130] T target =ω 1 I+ω 2 ·T+ω 3 I P +ω 4 ·T P , where T is the ambient color temperature, T P is the first color temperature, I is the ambient light intensity, I P is the first light intensity, T target is the target color temperature, ω 1 is the first weight, ω 2 is the second weight, ω 3 is the third weight, ω 4 The fourth weight.

[0131] In some embodiments, step 120 may include:

[0132] The ambient light intensity, the ambient color temperature, the first light intensity and the first color temperature are input into the target prediction model to obtain the target color temperature corresponding to the lighting device output by the target prediction model.

[0133] In this embodiment, the target prediction model can be obtained by training through machine learning or deep learning technology.

[0134] The target prediction model is trained using sample data from a variety of environments, including sample ambient light intensity, sample ambient color temperature, sample user light intensity and sample user color temperature, as well as the sample adjusted color temperature corresponding to these parameters (i.e., the actual output color temperature corresponding to the lighting device).

[0135] The sample data can be input into the target prediction model to obtain the predicted color temperature output by the target prediction model, and the target prediction model can be trained based on the difference between the predicted color temperature and the sample adjusted color temperature until the difference between the predicted color temperature and the sample adjusted color temperature meets the preset conditions. The trained target prediction model can be used as the final prediction model.

[0136] Sample data can be collected through experiments, user feedback, or simulations.

[0137] In some embodiments, step 120 may include:

[0138] Based on the environment in which the lighting device is located, obtaining at least one of the first light intensity and the first color temperature corresponding to the environment from at least one first light intensity and at least one first color temperature input by a user;

[0139] Based on at least one of the ambient light intensity and the ambient color temperature, and at least one of the first light intensity and the first color temperature corresponding to the environment, a target color temperature corresponding to the lighting device is acquired.

[0140] In this embodiment, the user can input preference settings corresponding to different environmental conditions. For example, the user can input light intensity preference and color temperature preference under cloudy, sunny, morning, afternoon or evening environments.

[0141] Or you can enter preference settings for different scene modes. For example, users can enter light intensity and color temperature preferences for reading, relaxing, or working modes.

[0142] Based on the environment in which the lighting device is located, the preference settings input by the user in the environment can be obtained. For example, when the environment in which the lighting device is located is morning, the first light intensity and first color temperature corresponding to the morning input by the user can be obtained.

[0145] An embodiment of the present application also provides a control device for a lighting device.

[0146] like Figure 3 As shown, the control device of the lighting device includes: a first processing module 310 , a second processing module 320 and a third processing module 330 .

[0147] The first processing module 310 is used to obtain at least one of the ambient light intensity and the ambient color temperature in the environment where the lighting device is located;
