Description

Technical Field

[0001] The present disclosure relates to the field of intelligent lighting technology, and in particular to an intelligent lighting control method and device. Background Art

[0002] In existing intelligent lighting control systems, many lighting systems integrate human body sensing and light sensing functions, and can automatically adjust the lighting status according to user behavior.

[0003] However, there are still some problems in the existing technology during actual use, which bring troubles to users.

[0004] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in this technical field. Summary of the Invention

[0005] One objective of this disclosure is to provide an intelligent lighting control method and device that flexibly selects the timing of ambient lighting intervention by combining the timing of user entry into a space with temporal characteristics (parameters) of historical lighting control operations. By adjusting the time window and synergizing the lighting control strategy, problems caused by delayed or misjudged lighting data can be effectively avoided, ensuring that intelligent lighting devices are turned on and off promptly according to the user's desired conditions.

[0006] Another object of this disclosure is to provide an intelligent lighting control method and device. By combining time-correlated parameters of human behavioral events and historical lighting control operations, the technical solutions provided by the embodiments of this disclosure can accurately determine the timing of lighting intervention under varying lighting conditions and user behavior timing. Specifically, this method, through predefined time windows and multiple differentiated response strategies, flexibly addresses lighting requirements in diverse scenarios, significantly improving the precision of lighting output control and enhancing the user experience.

[0007] Another object of the present disclosure is to provide an intelligent lighting control method and device, wherein the predetermined time window is at least partially dependent on a user-adjustable custom time component.

[0008] Another object of the present disclosure is to provide an intelligent lighting control method and device, wherein the applicable timing of different ambient lighting judgment conditions is not fixed, but can be dynamically adjusted according to user needs. The user adjusts the size of the predetermined time window by adjusting configurable parameters, thereby directly changing the applicable timing of the first strategy and the second strategy.

[0009] Another object of the present disclosure is to provide an intelligent lighting control method and device, wherein the custom time component only occupies part of the predetermined time window, and the fixed delay component is determined according to preset fixed parameters, and the fixed parameters are configured when the device leaves the factory and cannot be adjusted by the user.

[0010] Another object of the present disclosure is to provide an intelligent lighting control method and device, wherein user-configurable parameters (such as lighting transition parameters) used to adjust custom time components also have specific lighting adjustment functions, and the lighting adjustment functions are linked to predetermined time windows.

[0011] Another object of this disclosure is to provide an intelligent lighting control method and device, in which adjustment of the lighting off transition time directly affects the length of the custom time component, thereby affecting the duration of the overall predetermined time window. This mechanism enables the lighting off transition time to be "embedded" into the predetermined time window, creating an integrated control effect.

[0012] Another object of the present disclosure is to provide an intelligent lighting control method and device, wherein the first strategy can ensure that under any ambient lighting conditions, when the user enters the target space within the predetermined time window, the intelligent lighting device can always respond in a timely manner, meet the user's immediate needs, and provide a more convenient lighting experience. This is particularly effective in the event of sudden entry, avoiding the inconvenience caused by the lighting judgment conditions.

[0013] Another objective of this disclosure is to provide an intelligent lighting control method and device that dynamically selects the most appropriate response strategy based on user-defined time windows, ambient lighting parameters, and trigger timing, ensuring precise, flexible, and efficient lighting control. This design effectively avoids unnecessary delays and optimizes the user's lighting experience based on specific scenarios, enhancing lighting automation and responsiveness.

[0014] Another object of the present disclosure is to provide an intelligent lighting control method and device that, after turning a light on or off, determines whether an update to the lighting level is needed and, if necessary, reports the current ambient light level to ensure that the relationship between the user's perceived lighting level and a threshold value is consistent with the local lighting level.

[0037] The embodiments of the present disclosure will be described in detail below. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Obviously, the embodiments described are only some of the embodiments of the present disclosure, not all of them.

Therefore, they should not be construed as limiting the present disclosure. The terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance or implicitly specify the number of technical features referred to. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of such features.

Those skilled in the art will understand the specific meanings of the above terms in the present disclosure based on the specific circumstances.

[0039] In various embodiments of the present disclosure, the symbol " / " indicates that it has two functions at the same time. The symbol "A and / or B" indicates that the combinations of the preceding and following objects connected by the symbol include "A", "B", and "A and B".

[0040] In addition, the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0041] Please refer to Figure 1 The smart lighting control system 100 provided in the embodiments of the present disclosure includes a smart lighting device 10, a gateway 20, a router 70, a cloud 30, a user terminal 40, and a switch device 50. The figure illustrates one smart lighting device 10, one switch device 50, and one user terminal 40. In an actual control system, there may be multiple smart lighting devices 10, switch devices 50, and user terminals 40. Communication between the smart lighting device 10, the gateway 20, the user terminal 40, and the switch device 50 can be performed using wireless signals, which can use protocols such as Bluetooth, radio frequency, and Wi-Fi.

[0042] In addition, the smart lighting device 10 can also be connected to the router 70 through the gateway 20 (such as a Bluetooth gateway), thereby accessing the Internet and communicating with the cloud 30.

[0043] The intelligent lighting device 10 can be understood as a lighting device that integrates human presence sensing and light detection functions, and is used to execute the control method described below. Therefore, the description of the control method below is essentially a detailed explanation of the operating process, functions, and specific implementation methods of the software and / or hardware in the intelligent lighting device 10.

[0044] In some embodiments, the intelligent lighting device 10 may not have the human body sensing function and the light detection function, but may only be a lighting device with dimming and color adjustment functions. Figure 2 As shown, the control system 200 may further include a human sensor 60. The human sensor 60 has both human presence sensing and light detection functions and is connected to the smart lighting device 10 via a wireless direct connection or a network. The human sensor 60 and the smart lighting device 10 are typically located in the same space. This allows the smart lighting device 10 to obtain the ambient light level of the current space and detect whether a person has entered the space through the human sensor 60.

[0045] The user terminal 40 may include but is not limited to smart phone, tablet computer and other intelligent terminal devices. The switch device 50 includes but is not limited to the following types:

[0046] Wall switch: A traditional wall switch that is powered by a neutral and live wire;

[0047] Wireless switch: A wireless switch powered by a battery or a self-generating motor.

[0048] When the switch device 50 is a wall switch, the smart lighting device 10 can be placed in the control channel of the switch device 50, thereby controlling the smart lighting device 10 by turning the wall switch on or off. At the same time, the wall switch can also interact with the smart lighting device 10 via wireless signals, thereby controlling the smart lighting device 10 to turn on or off lighting.

[0049] When the switch device 50 is a wireless switch, the smart lighting device 10 interacts with the wireless switch via wireless signals, thereby triggering the smart lighting device 10 to perform a lighting on or off operation.

[0050] As mentioned in the background section, many existing lighting control systems integrate human presence and light sensing capabilities, automatically adjusting lighting conditions based on user behavior. For example, a person turns on a light when they arrive and turns it off when they leave. However, existing technologies still face some practical challenges, particularly in determining light thresholds and controlling the timing of sensor data. These issues often fail to fully address the logic behind lighting on / off. In particular, even when lighting conditions meet expectations for turning on a light, there are still instances where the light fails to turn on, causing user frustration.

[0051] Specifically, currently, smart lighting devices or lighting control systems with light and occupancy sensing capabilities typically rely on real-time light and occupancy data to determine whether to turn on lamps. However, when the applicable conditions for light determination are unclear or there are data delays, misjudgments can occur. This misjudgment is particularly pronounced when the timing of a user's entry into a space, the timing of historical lighting operations, and the timing of ambient light condition determinations intersect. This can make it impossible to accurately determine whether to re-enable light control, thus impacting the user experience.

[0052] Based on this, the present disclosure provides an intelligent lighting control method and device, wherein the intelligent lighting method can be applied to the intelligent lighting device or the above-mentioned lighting control system. When the control method is applied to the intelligent lighting device, the processing module (e.g. Figure 7 When the control method is applied to the lighting control system, the intelligent lighting device (eg Figure 1 and Figure 2 The intelligent lighting device 10 in Figure 7 The smart lighting device 700 shown is used as the execution subject.

[0053] The intelligent lighting control method provided by this disclosure flexibly selects the timing of ambient lighting intervention by combining the timing of user entry with the temporal correlation characteristics (parameters) of historical lighting control operations. By adjusting the time window and synergizing the lighting control strategy, it effectively avoids problems caused by delayed or misjudged lighting data, ensuring that intelligent lighting devices are turned on and off promptly according to the user's desired conditions.

[0054] like Figure 3 , which shows a flow chart of an intelligent lighting control method provided by the present disclosure; it can be seen that the method 300 at least includes steps S301 to S304.

[0055] In step S301, human behavior events in a target space are detected.

[0056] Specifically, the target space can be understood as a specific area or place where lighting needs to be controlled, such as a room, corridor, conference room, etc. When user activity in the target space is detected (for example, a human body enters the space), the relevant lighting control strategy will be activated to ensure that the lighting function is only controlled where it is needed. The human behavior event can be understood as an event or action related to human activity, which is captured by a human sensor (such as an infrared sensor or a motion sensor) or a human sensing module. These events may include a first event in which a human body enters the target space, a second event in which a human body leaves the target space, and so on.

[0057] In step S302, in response to detecting a first event of a person entering the target space, a time correlation parameter between the current moment and the historical lighting control operation is obtained. This time correlation parameter is used to reflect the temporal relationship between the first event occurrence time and the previous lighting state, and serves as a key basis for selecting a response strategy in this disclosure.

[0058] The current moment refers to the actual time point, used to determine the exact moment when the user enters the target space and triggers the first event. Historical lighting operations refer to lighting control actions executed before the current moment, such as turning the lights on or off. These historical operations influence the current lighting control decision and, in turn, the final selected response strategy.

[0059] In some embodiments, prior to detecting a first event in which a user enters a target space, the process further includes: determining that the target space is unoccupied. In this case, only if the target space is confirmed to be unoccupied before the first event is triggered, then the time-related parameters are obtained and the related operations are continued after the first event is triggered.

[0060] In addition, in some embodiments, the control method further includes: in response to a second event in which the user leaves the target space, performing a lighting off operation by switching the state (from "occupied" to "unoccupied"), and keeping the lighting off during the period in which it is determined that the target space is unoccupied.

[0061] To ensure accurate determination of the target space's status, a combination of moment-of-day and period-of-day determination methods is employed. Specifically, if the target space is detected to be unoccupied and remains unoccupied for a specified period of time, the target space is considered unoccupied. This specified period can be flexibly adjusted based on user needs, for example, between 1 second and 30 minutes. A shorter specified period results in higher determination efficiency, but may slightly reduce accuracy. Conversely, a longer period results in higher accuracy but slightly lower efficiency.

[0062] In step S303, based on the matching result between the time-related parameter and the predetermined time window, a target response strategy is selected from a plurality of response strategies having differentiated ambient light condition determination logics.

[0063] Specifically, the response strategy can be understood as the specific lighting control measures that the intelligent lighting device or system determines based on preset rules or conditions after receiving a trigger from an external event (such as a first event, a second event, etc.). By dynamically selecting the appropriate response strategy based on the relationship between time-related parameters and a predefined time window, the system achieves more precise and efficient lighting control.

[0064] In step S304, the target response strategy is executed to control the lighting output.

[0065] Specifically, based on the selected target response strategy, corresponding lighting control operations are executed to adjust or enable lighting output. For example, appropriate control measures are taken to adjust the state of smart lighting devices. For example, if the selected response strategy requires turning on the lights, the lighting device's lighting enable operation is triggered; if the selected strategy requires turning off the lights, the lighting device's lighting off operation is executed (or maintained). This ensures that lighting output matches user behavior and the pre-set time window.

[0066] Furthermore, by combining the time-correlated parameters of human behavioral events and historical lighting control operations, the technical solutions provided by the disclosed embodiments can accurately determine the timing of lighting intervention under different lighting conditions and user behavior timing. In particular, this method, through predefined time windows and multiple differentiated response strategies, flexibly responds to lighting needs in different scenarios, significantly improving the accuracy of lighting output control and enhancing the user experience.

[0067] In some embodiments, the predetermined time window is at least partially determined based on user-configurable parameters. The user-configurable parameters are used to adjust the applicable conditions of the response strategy. Because different response strategies have different logic for determining ambient lighting conditions, the user-configurable parameters can be used to adjust the applicable timing of different ambient lighting determination conditions.

[0068] In the disclosed embodiments, the timing for applying different ambient lighting conditions is not fixed but can be dynamically adjusted based on user needs. Users can adjust the size of the predetermined time window by adjusting configurable parameters, thereby directly changing the timing for applying the first and second strategies. Furthermore, by adjusting these user-configurable parameters, users can achieve the following: shortening the time window in spaces requiring rapid response (such as corridors) to increase the frequency of application of the first strategy; and extending the time window in spaces requiring energy conservation (such as warehouses) to strengthen the second strategy's lighting condition assessment.

[0069] In some embodiments, the user-configurable parameters are used to determine a custom time component, ie, the entire predetermined time window is configurable according to user needs.

[0070] Specifically, the predetermined time window includes a user-configurable custom time component (e.g., the predetermined time window consists only of the custom time component). The size of the predetermined time window is dynamically adjusted as the custom time component changes, and the adjustment trend of the custom time component is positively correlated with the change trend of the predetermined time window.

[0071] In the disclosed embodiments, the adjustment of the scheduled time window is directly influenced by the user-defined time component. By adjusting this time component, the user can directly control the size of the scheduled time window. For example, when the user increases the custom time component, the scheduled time window increases accordingly; conversely, when the user decreases the custom time component, the scheduled time window decreases accordingly. The changes between the two show a positive correlation.

[0072] Furthermore, the user-configurable parameters are used to determine a custom time component, and the predetermined time window is formed by linearly superimposing the custom time component and the fixed delay component.

[0073] In the disclosed embodiment, the predetermined time window includes a user-configurable custom time component and a fixed delay component determined by predetermined fixed parameters. The predetermined time window dynamically adjusts as the custom time component changes, and the changing trend of the custom time component is positively correlated with the changing trend of the predetermined time window. In this case, the custom time component only occupies a portion of the predetermined time window, while the fixed delay component is determined by preset fixed parameters. These fixed parameters are configured at the factory and cannot be adjusted by the user.

[0074] In order to further ensure the adjustability of the predetermined time window, the embodiment of the present disclosure further stipulates the proportional relationship between the custom time component and the fixed delay component. Specifically, the ratio of the upper limit T1 of the custom time component to T is greater than or equal to 1 / 2, where T is the predetermined time window, T=T1+T2, and T2 is the fixed delay component determined according to fixed parameters; the ratio of the lower limit T1' of the custom time component to T' is less than or equal to 1 / 10, where T'=T1'+T2. Through this design, the ratio of the custom time component to the fixed delay component changes dynamically with the adjustment of the custom time component, thereby further enhancing the user's control flexibility over the predetermined time window.

[0075] In some embodiments, the user-configurable parameters (eg, lighting transition parameters) used to adjust the custom time component also have a specific lighting adjustment function, and a linkage is established between the lighting adjustment function and the predetermined time window.

[0076] Specifically, the custom time component is determined based on the lighting transition parameters, and the lighting transition parameters themselves have a specific lighting adjustment function, and the duration required to execute this function is linked to the predetermined time window; by adjusting the lighting transition parameters, the user indirectly configures the duration of the custom time component, thereby embedding the duration into the predetermined time window.

[0077] In the disclosed embodiments, lighting transition parameters control the change of one or more lighting parameters (such as brightness and color temperature) during the lighting device's activation and deactivation process. The smoothness and duration of these lighting parameter changes are determined by the values ​​of the lighting transition parameters. By adjusting the lighting transition parameters, users can achieve a smooth transition from one lighting state to another (for example, from high brightness to low brightness, or from warm color temperature to cool color temperature).

[0078] Specifically, the adjustment of lighting transition parameters not only controls the speed at which lighting equipment is enabled or disabled, but also adjusts the length of the predetermined time window through linkage, so that the change process of lighting parameters matches the time span of user needs, thereby ensuring the flexible response of lighting control and dynamic adaptation to user needs.

[0079] Through this ingenious design, users can not only control the changes in lighting parameters when turning the lighting on or off, but also adjust the speed and smoothness of lighting changes according to actual needs to meet different lighting scenarios and user preferences.

[0080] Furthermore, the adjustment range of the lighting transition parameter is limited to [0, a] seconds, where the value range of a is 5≤a≤15 seconds. In addition, it is worth noting that the lower limit of the lighting transition parameter can be adjusted to 0. When the lighting transition parameter is 0, the predetermined time window will be fixed to [1, b] seconds, where 2≤b≤5. In this case, the predetermined time window will be fixed and will not be affected by user adjustments. When the value of the lighting transition parameter is 0, it means that there is no gradual transition effect when the lighting off operation is performed, that is, the lighting device will be turned off immediately. In this case, the predetermined time window is determined by the fixed delay component. Conversely, when the lighting transition parameter value is greater than 0, the predetermined time window will have a dynamic adjustment function, and its size will change according to the adjustment of the lighting transition parameter, thereby forming a flexible and adjustable predetermined time window.

[0081] Furthermore, the lighting transition parameters further include a lighting off transition time, and the lighting off transition time is used to determine the brightness change time when performing the lighting off operation; the length of the preset time window is determined by the sum of the custom time component determined by the lighting off transition time and the fixed delay component determined by the fixed parameters, that is, the length of the preset time window is formed by the linear superposition of the custom time component determined by the lighting off transition time and the fixed delay component determined by the fixed parameters.

[0082] In this embodiment, the lighting off transition time, as a lighting transition parameter, not only controls the speed of brightness change during the lighting device's lighting off operation but also interacts with the length of the predetermined time window. Specifically, adjusting the lighting off transition time directly affects the length of the custom time component, thereby affecting the overall duration of the predetermined time window. This mechanism allows the lighting off transition time to be "embedded" within the predetermined time window, creating an integrated control effect.

[0083] This adjustment mechanism allows users to flexibly control the speed of brightness changes during the lighting shutdown process and precisely adjust the duration of the brightness change. If users prefer a more rapid brightness reduction when the lighting device is turned off, they can shorten the lighting shutdown transition time, which will shorten the custom time component and thus reduce the overall duration of the predetermined time window. Conversely, if users prefer a smoother and more gradual lighting shutdown process, they can extend the lighting shutdown transition time, increasing the brightness change time and thus extending the duration of the predetermined time window.

[0084] In this specific example, a takes a value of 10, and / or b takes a value of 3. In this case, the adjustment range of the lighting off transition time is set to [0,10] seconds, and the range of the fixed parameter is set to [1,3] seconds. If the fixed parameter takes a value of 3, the scheduled time window will be adjustable within the range of [3,13] seconds, of which the custom time component will be adjustable within the range of [0,10] seconds. For example, when the lighting off transition time is set to 5 seconds, the time required for the lighting device to gradually decrease from the current brightness to completely off is 5 seconds, and the custom time component is 5 seconds. If the fixed delay component is 3 seconds, the overall scheduled time window is 8 seconds. When the lighting off transition time is set to 0 seconds, the scheduled time window will be determined only by the fixed delay component, that is, it will be fixed at 3 seconds, and the lighting device will be turned off immediately, and there will be no gradual brightness change.

[0085] Furthermore, in some embodiments, the predetermined time window can be set as a fixed time window. In this case, the lighting transition parameter remains adjustable to control the brightness change during the lighting device activation and deactivation process, but the size of the predetermined time window is no longer directly linked to the lighting transition parameter. In this case, the size of the predetermined time window is fixed and cannot be adjusted, and the lighting transition parameter only affects the duration of the lighting adjustment function.

[0086] Specifically, in this solution, the fixed time window can be set to be at least 1 second larger than the maximum adjustable value of the lighting transition parameter. This allows users to adjust the lighting transition parameter as needed to precisely control the transition effect of the lighting device without directly affecting the preset fixed time window.

[0087] In some embodiments, user-configurable parameters are used to determine the custom time component, while lighting transition parameters are used to control a specific lighting adjustment function. The execution duration of the lighting adjustment function and the custom time component are linearly superimposed to determine the total length of the predetermined time window.

[0088] In this embodiment, the lighting transition parameters and the custom time component are independent of each other: the custom time component can be set using a separate adjustment parameter, while the lighting transition parameters are adjusted separately. In other words, the predetermined time window is divided into two parts: the first part is determined by the lighting transition parameters, and the second part is determined by the user-configured adjustment parameters (i.e., the custom time component). Both parts can be adjusted independently, providing users with greater flexibility and personalized control.

[0089] The adjustment range of the lighting transition parameter is limited to [0, a] seconds, where a is 5 ≤ ​​a ≤ 15 seconds. This range ensures users can flexibly control the lighting gradient effect to suit different lighting scenarios and needs. It is worth noting that the lower limit of the lighting transition parameter can be adjusted to 0 seconds. In this case, the scheduled time window is completely determined by the custom time component. In this case, the custom time component range is [0, b] seconds, where 3 ≤ b ≤ 15 seconds. When the custom time component is set to 0, the scheduled time window is determined solely by the lighting transition parameter.

[0090] When both the lighting transition parameters and the custom time component are set to 0, the predefined time window is canceled. In this case, when the user triggers the first event, the second strategy is always executed, and the first strategy is disabled. This design provides greater control precision, ensuring that in certain situations, users can force a simpler, more direct lighting control strategy.

[0091] The lighting transition parameters further include a lighting off transition time, which is used to determine the brightness change time when the lighting is turned off; that is, the predetermined time window is formed by the linear superposition of the lighting off transition time and the custom time component. Here, a takes a value of 10 and b takes a value of 5. For example, when the value of a for the lighting off transition time is 10 seconds and the value of b for the custom time component is 5 seconds, the total duration of the predetermined time window will be 15 seconds. This means that when the lighting is turned off, the device will gradually reduce the brightness within 10 seconds, and the remaining 5 seconds will be controlled by the custom time component. Users can freely adjust these two time parameters according to their needs to obtain the most ideal lighting effect.

[0092] Through this independent configuration of lighting transition parameters and custom time components, users can achieve detailed control of lighting effects. Flexible time window settings make lighting control more intelligent and can be personalized according to actual scene requirements.

[0093] In some embodiments, the historical lighting control operation includes a lighting off operation; obtaining the time correlation parameter between the current moment and the historical lighting control operation specifically includes: obtaining the time interval between the current moment triggered by the first event and the most recent lighting off operation.

[0094] Furthermore, the time-related parameter includes the time interval between the current moment and the last lighting off operation.

[0095] The method of selecting a target response strategy from a plurality of response strategies having differentiated ambient light condition determination logics based on the matching result of the time correlation parameter and the predetermined time window comprises:

[0096] like Figure 4 and Figure 5 As shown in the figure, a detailed schematic diagram of the control process is shown. Figure 4 and Figure 5 As can be seen, when selecting a response strategy, the first step is to determine whether the time interval is within the predetermined time window. If the time interval is within the predetermined time window, the first strategy is selected; otherwise, the second strategy is selected. It is worth noting that the first and second strategies differ in the logic of determining ambient lighting conditions.

[0097] Specifically:

[0098] The degree of match between the time interval and a predetermined time window is determined. When the time interval is within the predetermined time window, a first strategy is selected as the target response strategy to control the lighting output based on the triggering of the first event. Otherwise, a second strategy is selected as the target response strategy to control the lighting output based on a first comparison result between the ambient lighting parameter and a first lighting threshold. The first lighting threshold can be changed according to user settings.

[0099] In the embodiment of the present disclosure, the first strategy prioritizes controlling the lighting output based on the human body sensing signal, while the second strategy comprehensively considers the impact of the human body sensing signal and the ambient light conditions on the lighting output. Furthermore, when the first strategy is adopted, if it is determined that the first event is triggered (i.e., it is confirmed that someone has entered / existed in the target space), the influence of the current ambient light parameters is ignored, and a lighting turn-on instruction is directly generated to execute the lighting enable operation without relying on the first light threshold determination. Furthermore, the first strategy can ensure that under any ambient light conditions, when the user enters the target space within the predetermined time window, the intelligent lighting device can always respond in a timely manner, meet the user's immediate needs, and provide a more convenient lighting experience. This is particularly effective in the event of sudden entry, avoiding the inconvenience caused by the light determination conditions.

[0100] Furthermore, by setting a preset time window to distinguish the timing of human entry into the space, it is decided whether to prioritize human sensing signals or give equal weight to human sensing signals and ambient light according to the timing. When the time difference between the time when the user enters the space and the time when the lights were last turned off is small, the human sensing signal should be responded to first to reduce unnecessary judgments and delays, thereby improving the real-time and accuracy of lighting output control and ensuring that smart lighting equipment can be turned on stably as expected.

[0101] It should be noted that Figure 4 、 Figure 5 and subsequent Figure 6 This diagram only illustrates the interaction between the smart lighting device 10 and the user terminal 40, and does not cover the specific interactions between the gateway 20, router 70, and cloud 30. The reporting operations (such as reporting the first event and reporting the current ambient light level) shown in the diagram can be understood as the smart lighting device 10 establishing a communication link with the router 70 through the gateway 20 and uploading relevant data to the cloud 30. The user terminal 40 then obtains and updates the data through the cloud 30.

[0102] Furthermore, the ambient light parameter includes ambient light illuminance, which can be obtained by a photosensor carried by the lighting device itself, or by an external light sensor, and then transmitted directly or indirectly to the intelligent lighting device via a wired or wireless method for use. Based on this, controlling the lighting output based on a first comparison result of the ambient light parameter and a first light threshold specifically includes: triggering a lighting activation operation when the current ambient light illuminance falls within a range less than or equal to the first light threshold; otherwise, executing a lighting deactivation operation.

[0103] Specifically, if Figure 4 and Figure 5As shown in FIG, after selecting the second strategy as the target response strategy, the current ambient light illuminance is first obtained and compared with the first light threshold. If the current ambient light illuminance is less than or equal to the first light threshold, the lighting is enabled; otherwise, the lighting is kept off.

[0104] In addition, in the embodiment of the present disclosure, the time of executing the lighting off operation can be understood as the start time of triggering the lighting off operation. The following is an example of an application scenario of corridor smart lighting:

[0105] The user sets the custom time component to 10 seconds and the fixed delay component to 3 seconds. The first light threshold is set to 100 lux. Suppose the user triggers the light-off operation at 20:00:00, and the light-off operation completes at 20:00:10. In this case, the trigger time for the light-off operation is 20:00:00. As described above, the scheduled time window is determined by both the custom time component and the fixed delay component. Therefore, in this example, the scheduled time window is 13 seconds. In this application scenario, the custom time component is embedded as part of the scheduled time window. If a person enters at 20:00:12, the time interval is 12 seconds. Since 12 seconds is less than 13 seconds, the first strategy is selected, and the lights are turned on directly. If a person enters at 20:00:18, the time interval is 18 seconds. Since 18 seconds is greater than 13 seconds, the second strategy is selected, and the light sensor is activated to detect the current ambient light level. If the current ambient light intensity is 80 lux (lower than 100 lux), the lighting is turned on; if the current ambient light intensity is 200 lux (higher than 100 lux), the lighting is kept off.

[0106] This solution dynamically selects the most appropriate response strategy based on user-defined time windows, ambient lighting parameters, and trigger timing, ensuring precise, flexible, and efficient lighting control. This design effectively avoids unnecessary delays and optimizes the user lighting experience based on specific scenarios, improving lighting automation and responsiveness.

[0107] In some embodiments, when the time interval exceeds the custom time component but is still within the fixed delay component, based on the triggering of the first event, the lighting device will adjust the brightness from 0% to the initial brightness (i.e., the brightness before performing the lighting shutdown operation) in a sudden or gradual manner.

[0108] When the time interval is within the custom time component, based on the triggering of the first event, the lighting enable operation can be performed in one of the following ways:

[0109] Method 1: Stop the current brightness adjustment operation and gradually adjust the brightness in the reverse direction to the initial brightness, that is, start from the current brightness (such as 10%) and gradually increase it until it reaches the initial brightness (such as 80%).

[0110] Method 2: Continue adjusting the brightness in the current direction until it reaches 0%, then gradually adjust the brightness back to the initial brightness. That is, continue to decrease the brightness from 10% to 0%, and then gradually increase it back to 80%.

[0111] Method 3: Stop the brightness adjustment operation in the current direction and adjust the brightness directly to the initial brightness, that is, adjust it directly from 10% to 80% without the gradual process.

[0112] Method 4: Continue adjusting the brightness in the current direction until it drops to 0%, then adjust the brightness back to the initial brightness, that is, adjust it directly from 0% to 80%.

[0113] Among them, in the third and fourth methods, the brightness adjustment is sudden, that is, it jumps directly to the target brightness. In the first and second methods, the brightness adjustment is gradual, that is, the brightness is adjusted through smooth transition.

[0114] For example, assuming the initial brightness of the smart lighting device is 80%, the custom time component determined by the lighting transition parameters is 10 seconds, and the fixed delay time is 3 seconds, the predetermined time window is 13 seconds. If, after the lighting is turned off, the time interval between the triggering of the first event and the lighting off time is 7 seconds (this time interval falls within the custom time component), different control strategies are adopted:

[0115] Method 1: Stop the current brightness adjustment operation and gradually increase the brightness from 10% to 80% (i.e., reverse gradient).

[0116] Method 2: Continue to lower the brightness to 0%, and then gradually increase it from 0% to 80% (i.e. first gradually change to 0%, and then reverse the gradient).

[0117] Method 3: Stop the current brightness adjustment operation and adjust directly from 10% to 80% (mutation method).

[0118] Method 4: Continue to lower it to 0%, and then adjust it directly from 0% to 80% (mutation method).

[0119] If the time interval for triggering the first event is 11 seconds (greater than the custom time component but less than or equal to the fixed delay component), the brightness adjustment will adopt a sudden or gradual change method to directly adjust the brightness from 0% to 80% of the initial brightness.

[0120] These adjustment methods allow users to precisely control the lighting device's on / off process based on their needs. Gradual adjustment provides a smooth transition, while abrupt adjustment allows for a more immediate response. Whether it's a quick response or a smooth transition, flexibility is provided to meet diverse user experience requirements.

[0121] In some embodiments, the time-related parameter specifically includes the time interval between the current moment and the last lighting off operation;

[0122] Based on the matching result of the time correlation parameter and the predetermined time window, a target response strategy is selected from a plurality of response strategies with differentiated ambient light condition determination logics; comprising:

[0123] According to the degree of matching between the time interval and the predetermined time window, when the time interval is within the predetermined time window, the first strategy is selected as the target response strategy; otherwise, the second strategy is selected as the target response strategy; wherein, the first strategy and the second strategy differ in the logic of determining the ambient lighting conditions.

[0124] Specifically, if Figure 6 As shown, a more detailed control flow diagram is provided. After a first event is triggered, the time interval between the first event triggering moment (the current moment) and the most recent lighting shutdown operation is obtained, and the degree of matching between the time interval and a predetermined time window is determined. If the time interval is within the predetermined time window, the first strategy is selected as the target response strategy, and the lighting output is controlled based on a first comparison result between the ambient lighting parameter and a second lighting threshold. Otherwise, the second strategy is selected as the target response strategy, and the lighting output is controlled based on a first comparison result between the ambient lighting parameter and a third lighting threshold. The second lighting threshold is greater than the third lighting threshold, and the second lighting threshold is either a default value or set by the user, while the third lighting threshold can be changed according to the user's setting.

[0125] Furthermore, the ambient light parameter includes ambient light illuminance; controlling the lighting output based on a first comparison result of the ambient light parameter and the second light threshold value; specifically comprising: triggering a lighting enabling operation when the current ambient light illuminance falls within a range less than or equal to the second light threshold value; otherwise, performing a lighting shutoff operation; or,

[0126] The lighting output is controlled based on a first comparison result between the ambient light parameter and the third light threshold; specifically, the lighting output is controlled. When the current ambient light illuminance falls within a range less than or equal to the third light threshold, a lighting activation operation is triggered; otherwise, a lighting deactivation operation is performed.

[0127] Furthermore, in the embodiment of the present disclosure, when the time interval is within the predetermined time window, the first response strategy is selected, and the following operations are performed:

[0128] a) Get the current ambient light intensity;

[0129] b) comparing the ambient light intensity with a second light threshold;

[0130] c) generating a lighting on instruction and executing a lighting enabling operation when the ambient light illumination is less than or equal to a second lighting threshold, otherwise maintaining the lighting off state;

[0131] The second illumination threshold is set to a reference value higher than conventional lighting requirements (preferably in the range of 200-500 lux), and supports user customization or default value;

[0132] When the time interval exceeds the predetermined time window, a second response strategy is selected, and the following operations are performed:

[0133] d) Get the current ambient light intensity;

[0134] e) comparing the ambient light illumination with a third light threshold;

[0135] f) generating a lighting on instruction and executing a lighting enabling operation when the ambient light illumination is less than or equal to a third lighting threshold, otherwise maintaining the lighting off state;

[0136] The third illumination threshold is set to an energy-saving threshold lower than the second illumination threshold (preferably in the range of 50-150 lux), and supports dynamic adjustment by users.

[0137] The mathematical relationship between the thresholds satisfies: second illumination threshold ≥ third illumination threshold × k, where k is an adjustable coefficient between 1.5 and 3.0. This relationship ensures that a more relaxed illumination condition judgment standard is used when short-term repeated triggering occurs.

[0138] Take the office smart lighting scenario as an example: the scheduled time window is 8 seconds; the second light threshold is 300 lux (fixed value); the third light threshold is 100 lux (user-adjustable).

[0139] Scenario A (short return): The user leaves at 18:00:00, triggering the lights to turn off, and the lights fade out at 18:00:04; they re-enter at 18:00:05 (interval 6 seconds < 8 seconds), and the light intensity is detected to be 250 lux (≤ 300 lux), and the lights are turned on immediately.

[0140] Scenario B (long time interval): The user leaves at 18:00:00 and re-enters at 18:30:00 (interval 1800 seconds > 8 seconds); the detected light intensity is 120 lux (> 100 lux), and the lights remain off.

[0141] In addition, the user configuration method of the lighting transition parameter (lighting off transition time), the first lighting threshold, the second lighting threshold and / or the third lighting threshold involved in the above embodiment includes but is not limited to at least one of the following:

[0142] Dynamic adjustment through mobile terminal applications;

[0143] Setting through the physical control interface of the lighting device (such as knobs, touch panels);

[0144] Automatically optimized through machine learning algorithms based on historical usage data.

[0145] In some embodiments, as Figure 4 and Figure 6 As shown, after obtaining the current ambient light illumination, the method further includes: reporting the current ambient light illumination so that the cloud directly or indirectly obtains the current ambient light illumination and updates the illumination display of the user terminal according to the current ambient light illumination.

[0146] Furthermore, after turning the light on and off, the current ambient light level is proactively reported to ensure that the relationship between the light level seen by the user and the threshold is consistent with the local light level. This prevents the situation where the light level seen by the user on the app is less than the threshold while the actual light level on the device is greater than the threshold.

[0147] In some embodiments, as Figure 5 As shown, after obtaining the current ambient light illumination, the method further includes:

[0148] determining a second comparison result of the historical light level and the first light threshold;

[0149] Determine whether the second comparison result is consistent with the first comparison result; if there is inconsistency, report the current ambient light intensity so that the cloud updates the light intensity display of the user terminal; otherwise, do not report; wherein the historical light intensity is the ambient light intensity reported last time.

[0150] After turning the light on and off, the system determines whether an update to the ambient light is needed. If necessary, the system reports the current ambient light level to ensure that the relationship between the user's perceived light level and the threshold is consistent with the local light level. This prevents situations where the user sees a light level lower than the threshold on the app, while the actual device's current light level is higher than the threshold.

[0151] Furthermore, the historical illuminance is the ambient illuminance reported to the cloud when the illuminance obtained according to the second illuminance acquisition method meets specific illuminance reporting conditions (for example, within the set time, the illuminance change exceeds a certain value, such as within 5 seconds, the illuminance change exceeds 100 lux, then the changed illuminance is reported). The current ambient illuminance is obtained based on the first illuminance acquisition method; the first illuminance acquisition method is different from the second illuminance acquisition method.

[0152] Specifically, the first lighting acquisition method obtains real-time lighting, which is used to reflect the instantaneous lighting conditions of the environment, so that the second strategy can quickly determine the ambient lighting conditions for lighting output control. The second lighting acquisition method obtains stable lighting, which is used for automatic updating and reporting of lighting, so it is necessary to obtain stable lighting values. In a specific example, the first lighting acquisition method includes: selecting the most recent N ADC values, taking the median, and representing the real-time illuminance. In another specific example, the first lighting acquisition method includes: selecting the most recent N ADC values, removing the maximum and minimum, and calculating the average to represent the real-time illuminance. This can avoid glitches in the lighting data to a certain extent. Real-time illuminance is the current ambient illuminance. The ADC value here is transmitted from the photosensor module to the processing module, representing the electrical signal converted by the photosensor module after sensing the ambient illuminance. The value of N is 3 to 5.

[0153] The second lighting acquisition method includes: caching real-time illuminance data into a sliding window (the length of the sliding window is determined by the set time), and then calculating the standard deviation of all illuminance data in the sliding window. When the standard deviation is less than a preset value, it means that the lighting has stabilized. The lighting at this time is stable lighting. The stable lighting is compared with the previous stable lighting. When the change exceeds a certain value, it is reported to the cloud for daily update of the lighting display status in the user terminal.

[0154] Through the above two different lighting acquisition methods, we can effectively distinguish between instantaneous lighting values ​​and stable lighting values, so as to flexibly adjust the lighting control logic in different scenarios.

[0155] like Figure 7 As shown, according to the control method provided in the above embodiment, an embodiment of the present disclosure further provides an intelligent lighting device 700, which is used to implement the control method provided in the above embodiment, and adopts the control method to realize intelligent lighting; or the intelligent lighting device 700 is used for the intelligent lighting device 10 in the lighting system in the above embodiment, and the control method provided in the above embodiment is realized with the help of the lighting system.

[0163] Furthermore, the custom time component is determined according to the lighting transition parameter, which has a specific lighting adjustment function, and its execution duration is linked to the predetermined time window. The user indirectly adjusts the duration by adjusting the lighting transition parameter, thereby embedding it in the predetermined time window.

[0164] Furthermore, the adjustment range of the lighting transition parameter is [0, a] seconds, where 5≤a≤15; when the lighting transition parameter is 0, the predetermined time window will be fixed to [1, b] seconds, where 2≤b≤5.

[0165] Furthermore, the lighting transition parameters further include a lighting off transition time, which is used to determine the brightness change time when performing a lighting off operation; the length of the preset time window is formed by the linear superposition of a custom time component determined by the lighting off transition time and a fixed delay component determined by the fixed parameters.

[0166] Furthermore, a takes a value of 10, and / or b takes a value of 3.

[0167] In some embodiments, the time-related parameters include the time interval between the current moment and the most recent lighting shutdown operation; the processing module 702 is also configured to select a target response strategy from a plurality of response strategies with differentiated ambient lighting condition determination logics based on the matching result between the time-related parameters and the predetermined time window; specifically, it is used to: determine the degree of matching between the time interval and the predetermined time window, and when the time interval is within the predetermined time window, select the first strategy as the target response strategy, and control the lighting output according to the triggering of the first event; otherwise, select the second strategy as the target response strategy, and control the lighting output based on the first comparison result between the ambient lighting parameter and the first lighting threshold; wherein, the first lighting threshold can be changed according to user settings.

[0171] In some embodiments, the time-related parameters specifically include the time interval between the current moment and the most recent lighting-off operation; the processing module 702 selects a target response strategy from a plurality of response strategies with differentiated ambient lighting condition determination logics based on the matching result of the time-related parameters and the predetermined time window; specifically used to: determine the degree of matching between the time interval and the predetermined time window, and when the time interval is within the predetermined time window, select the first strategy as the target response strategy, and control the lighting output based on the first comparison result between the ambient lighting parameter and the second lighting threshold; otherwise, select the second strategy as the target response strategy, and control the lighting output based on the first comparison result between the ambient lighting parameter and the third lighting threshold; wherein the second lighting threshold is greater than the third lighting threshold, and the second lighting threshold is a default value or user setting, and the third lighting threshold can be changed according to the user setting.

[0172] Furthermore, the ambient lighting parameters include ambient light illuminance; the lighting output is controlled based on a first comparison result between the ambient lighting parameters and a second lighting threshold; specifically used to: trigger a lighting enable operation when the current ambient light illuminance falls within an interval less than or equal to the second lighting threshold; or, the lighting output is controlled based on a first comparison result between the ambient lighting parameters and a third lighting threshold; specifically including: triggering a lighting enable operation when the current ambient light illuminance falls within an interval less than or equal to the third lighting threshold.

[0173] In some embodiments, the processing module 702 is further configured to:
