Abstract

The application discloses a method and device for adjusting indoor brightness and a smart lamp, and relates to the technical field of smart home, and the method comprises the following steps: obtaining current indoor illumination, outdoor illumination and historical indoor illumination, and predicting the illumination to obtain predicted illumination. Since the predicted illumination not only considers the indoor and outdoor illumination at the current moment, but also considers the indoor illumination at the historical moment, the brightness that can be reached in the indoor after the lamp is turned off at the current moment can be effectively predicted. When the predicted illumination is strong, it is indicated that a certain brightness can be obtained even if the brightness of the lamp is adjusted to be low or the lamp is turned off. When the predicted illumination is weak, it is indicated that the brightness of the lamp needs to be used to ensure the indoor brightness. Therefore, the brightness of the lamp is adjusted to the target illumination range according to the predicted illumination, so that the effect of saving energy can be achieved while the indoor brightness is ensured.

[0010] Optionally, based on the correspondence between the brightness range and the control strategy, the target control strategy corresponding to the predicted illuminance is determined, including: when the predicted illuminance is greater than or equal to a first threshold, the target control strategy is determined to be a light-off strategy; when the predicted illuminance is less than the first threshold, the target control strategy is determined to be an adjustment strategy; wherein the first threshold is less than a second threshold, and the lower limit of the target illuminance range is greater than or equal to the first threshold, and the upper limit of the target illuminance range is less than or equal to the second threshold.

[0011] Optionally, the brightness adjustment device includes a curtain.

[0019] By acquiring current indoor illuminance, outdoor illuminance, and historical indoor illuminance, and then predicting the illuminance, a predicted illuminance is obtained. Since the predicted illuminance considers not only the current indoor and outdoor illuminance but also the historical indoor illuminance, it can effectively predict the indoor brightness that can be achieved after the lights are turned off. When the predicted illuminance is strong, it means that even if the brightness of the lights is reduced or the lights are turned off, a certain level of brightness can still be achieved. When the predicted illuminance is weak, it means that the brightness of the lights needs to be increased to ensure indoor brightness. Therefore, adjusting the brightness of the lights to the target illuminance range based on the predicted illuminance can achieve the effect of saving energy while ensuring indoor brightness.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] It should be understood that the terminal device 102 described in the embodiments of this application may be referred to as a user equipment, terminal device, etc. For example, the terminal device 102 is not limited to smart curtains and smart lamps.

[0037] Current smart lighting fixtures offer relatively uniform brightness levels when providing indoor light, failing to proactively adjust based on ambient light conditions and the current indoor lighting environment. For example, users may forget or be unaccustomed to turning off the lights when leaving the bathroom, or require the lights to be on to maintain adequate illumination on cloudy days or in low light conditions to minimize eye strain. Conversely, on sunny days with ample sunlight, the lights may not be necessary. This application's embodiment addresses these diverse lighting needs by making decisions based on user and environmental conditions. This eliminates energy waste caused by human and environmental factors and adjusts indoor brightness to better suit the user's current environment. Therefore, it solves the problem of eye fatigue caused by unsuitable brightness levels while meeting the user's lighting requirements.

[0038] Combination Figure 2 As shown in the figure, a method for adjusting indoor brightness is provided in an embodiment of this application. The method includes:

[0039] S201: Obtain the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0040] The current indoor illuminance refers to the indoor illuminance at the current moment, i.e., the actual brightness of the room at that moment, such as the brightness in a bathroom or bedroom. Illuminance can be obtained through various means, including light-sensing devices, smartphones, and various smart terminals with communication and storage functions. The acquired current indoor illuminance, outdoor illuminance, and historical indoor illuminance can be stored in the smart lighting fixture or in a separate data storage device. Besides using a dedicated computer system, the data storage device can reuse various hardware devices with data storage and computing functions, or be implemented through a combination of multiple smart hardware / devices with storage or computing functions.

[0041] Historical indoor illuminance can be the indoor illuminance before the current moment. Specifically, it can be the indoor illuminance before the lights were turned on, or it can be the indoor illuminance before the current moment when the weather conditions were the same as the current moment and the lights were not turned on.

[0042] S202: Determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0043] Predicted illuminance is used to characterize the illuminance that can be achieved indoors if indoor lights are turned off at the current moment.

[0044] S203: The brightness adjustment device is controlled according to the predicted illuminance and target illuminance range to adjust the indoor brightness.

[0045] The target illuminance range is the desired indoor illuminance. This range can be a factory setting or a user-defined range tailored to their specific needs. For example, let's consider a sunny summer day at 8:30 AM, in a 5-story residential building in Jinan, Shandong province, on the 5th floor, with a north-facing bathroom window. Under these conditions, the sensor measures the current indoor illuminance (after the lights are on) at 170 lx. The server retrieves the historical indoor illuminance (at 8:05 AM) before the lights were on, which is 150 lx. The outdoor illuminance is also measured in real-time by the sensor and can be obtained from a server storing weather information. Based on this combined information—current illuminance, outdoor illuminance, and indoor illuminance before the lights were on—the indoor illuminance is predicted to be no less than 150 lx for at least the next four hours. Even if the bathroom lights are turned off, the indoor illuminance will not fall below 150 lx, which is sufficient for the user's needs. Therefore, a command can be issued to turn off the lights. Alternatively, stored data retrieved from the server shows that on a sunny day in the same month of previous summers, the indoor illuminance (historical indoor illuminance) at 8:30 AM was 160 lx and at 10:20 AM it was 170 lx. Predicting that the indoor illuminance will not fall below 150 lx or 160 lx within the next two hours, turning off the bathroom lights would also ensure that the indoor illuminance remains at 150 lx, sufficient for the user's needs. Therefore, a command can be issued to turn off the lights.

[0046] The method provided in this application first obtains the current indoor illuminance, outdoor illuminance, and historical indoor illuminance, and then predicts the illuminance to obtain the predicted illuminance. Since the predicted illuminance considers not only the current indoor and outdoor illuminance but also the historical indoor illuminance, it can effectively predict the indoor brightness that can be achieved after the lights are turned off. When the predicted illuminance is strong, it means that even if the brightness of the lights is reduced or the lights are turned off, a certain level of brightness can still be obtained. When the predicted illuminance is weak, it means that the brightness of the lights is needed to ensure the indoor brightness. Therefore, adjusting the brightness of the lights to the target illuminance range according to the predicted illuminance can achieve the effect of saving energy while ensuring indoor brightness.

[0047] Optionally, obtaining outdoor illuminance in step S201 above includes: obtaining the building location, outdoor weather conditions, and current time; and determining the outdoor illuminance based on the building location, outdoor weather conditions, and current time.

[0048] Outdoor weather conditions refer to the external environment, such as the illuminance values ​​at sunny, cloudy, sunrise, and sunset times. Illuminance values ​​at various times can be obtained through reference values, which can be measured by illuminance detection equipment at different times. These reference values ​​can be pre-stored in the smart lighting fixtures for use in calculations, stored on a server, simulated by algorithm model software, or obtained from existing publicly available data for use by the smart lighting fixtures. Table 1 below shows reference values ​​for outdoor illuminance under various environmental conditions in some examples.

[0049] Table 1: (Unit: lx)

[0050]

[0051]

[0052] The outdoor illuminance at the current moment can be obtained by considering the scene at the current moment.

[0053] Optionally, obtaining historical indoor illuminance includes: retrieving a first historical illuminance and / or a second historical illuminance from a pre-stored data server; wherein the first historical illuminance is the indoor illuminance before the last time the lights were turned on before the current time; and the second historical illuminance is the indoor illuminance when the lights were not turned on before the current time, provided that the weather similarity to the current time is greater than a preset threshold and the time difference between the current time and the current time is less than a time threshold.

[0054] Combination Figure 3 As shown in the embodiment of this application, another method for adjusting indoor brightness includes the following steps:

[0055] S301: Obtain the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0056] S302: Determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0057] S303: When there are people indoors and the lights are on, obtain the brightness range of the predicted illuminance.

[0058] S304: Determine the target control strategy corresponding to the predicted illuminance based on the correspondence between the luminance range and the control strategy.

[0059] S305: A brightness adjustment device that adjusts the brightness according to the target control strategy and the target illumination range.

[0060] In the above embodiments, after determining the predicted illuminance, the brightness range of the predicted illuminance is obtained, and a corresponding target control strategy is determined based on the brightness range. The brightness is then adjusted according to the target control strategy so that the adjusted indoor brightness is within the target illuminance range. The correspondence between the brightness range and the control strategy can be a pre-stored correspondence in the smart lighting fixture or a pre-stored correspondence in a server communicating with the smart lighting fixture. This correspondence can be a mapping table or a relational function that uniquely determines the control strategy through the brightness range. This application does not limit the specific form of the correspondence in its embodiments.

[0061] Optionally, based on the correspondence between brightness range and control strategy, a target control strategy corresponding to the predicted illuminance is determined, including:

[0062] (1) If the predicted illuminance is greater than or equal to the first threshold, the target control strategy is determined to be the light-off strategy. In this case, if the predicted illuminance is greater than or equal to the first threshold, it means that the current indoor brightness may be a combination of outdoor brightness and indoor brightness. The indoor brightness may be too high, causing energy waste. At this time, the light-off strategy can be implemented to provide light source for the indoor environment through outdoor light, thereby achieving the purpose of saving energy.

[0063] (2) When the predicted illuminance is less than the first threshold, the target control strategy is determined to be an adjustment strategy; wherein the first threshold is less than the second threshold, and the lower limit of the target illuminance range is greater than or equal to the first threshold, and the upper limit of the target illuminance range is less than or equal to the second threshold. Thus, when the predicted illuminance is less than the first threshold, it indicates that the outdoor light may be insufficient. Therefore, the lights cannot be turned off directly, but rather the indoor brightness is adjusted in real time based on the outdoor illuminance and the current indoor illuminance. This ensures that the indoor illuminance always meets the user's needs and does not become too dim, thus improving the lighting effect of the smart lighting fixtures.

[0064] Specifically, the values ​​of the first threshold and the second threshold can be preset based on experience and stored in the smart lamp, or stored on the server connected to the smart lamp. Each time the smart lamp is turned on, the first threshold and the second threshold stored on the server are retrieved.

[0065] Furthermore, the first threshold and the second threshold are set according to the nature of the space in which the luminaire is located. The nature of the space includes, but is not limited to, the size and purpose of the space. That is, the first threshold and the second threshold are not fixed and can be set according to the nature of the space in which the luminaire is located. For example, if the space where the luminaire is located is a bathroom, where excessive brightness is not required, the first threshold and the second threshold can be set relatively small. If the space where the luminaire is located is a study, where brighter light is needed for reading, the values ​​of the first threshold and the second threshold can be set relatively large.

[0066] Preferably, the first threshold can be set to 100 lx and the second threshold can be set to 2200 lx.

[0067] The target illumination range can be an illuminance range comprised of a first threshold and a second threshold, or a smaller illuminance range between the first and second thresholds. For example, the target illumination range can be greater than or equal to a third threshold and less than or equal to a fourth threshold, where the third threshold is less than the fourth threshold, and the third threshold is greater than or equal to the first threshold, and the fourth threshold is less than or equal to the second threshold. Preferably, the third threshold can be set to 150 lx, and the fourth threshold can be set to 2000 lx.

[0068] Between the first and second thresholds, a third and fourth threshold, with even smaller ranges, are set. Users can individually set the third and fourth thresholds according to their preferences, or they can set the default values. The initial values ​​can be determined according to national standards such as the "Standard for Daylighting Design of Buildings" or relevant industry standards or specifications. The third and fourth thresholds represent the range most suitable for user vision protection or the range where users feel most comfortable under this lighting environment. This allows for a range that is more suitable for user visual health and provides a more comfortable experience in bright environments. Furthermore, the value range of the third and fourth thresholds can be adjusted according to actual needs, achieving more flexible brightness control. For example, for scenarios with lower requirements for eye protection and brightness adjustment precision, the third threshold can be set to a value with a small difference from the first threshold, and the fourth threshold can be set to a value with a small difference from the second threshold. Alternatively, the third threshold can be set to be equal to the first threshold, and the fourth threshold to be equal to the second threshold. In situations where eye protection is critical or where high brightness adjustment precision is required, the third threshold can be set to a value that differs significantly from the first threshold, and the fourth threshold can be set to a value that differs significantly from the second threshold. This allows for brightness adjustment within a smaller range, further improving the precision of brightness adjustment.

[0069] In some examples, the predicted illuminance can be determined based on multiple sets of illuminance data. Specifically, each set of illuminance data includes outdoor illuminance, historical indoor illuminance, and current indoor illuminance. For example, a curve can be plotted showing the relationship between outdoor illuminance, historical indoor illuminance, and indoor illuminance after the lights are turned on, using the multiple sets of illuminance data, and the predicted illuminance can be determined based on this curve. Alternatively, the daylight factor can be calculated first, and the predicted illuminance can be determined by looking up the value in a pre-defined illuminance calculation table. Of course, other methods can also be used to determine the predicted illuminance.

[0070] In some examples, the predicted illuminance can be determined based on the daylight factor, the building's daylighting rating, and the daylighting method.

[0071] The daylight factor can be determined based on the following methods:

[0072] C = (En / Ew) × 100%

[0073] Where C represents the daylight factor at any point indoors, En represents the indoor illuminance before the lights are turned on, and Ew represents the outdoor illuminance. Daylight factor and outdoor illuminance are described in various publicly available or promulgated environmental illuminance values. For daylight factor, refer to national standards such as the "Standard for Daylight Design of Buildings".

[0074] Based on the determined daylighting coefficients, the predicted illuminance can be determined by looking up a table. As an example, Table 2 below shows the standard daylighting values ​​on the reference plane for each daylighting level.

[0075] Table 2

[0076]

[0077] After determining the daylight factor at any point indoors, the standard value of indoor natural illuminance corresponding to the daylight factor can be determined in Table 2 based on the building's daylighting level and daylighting method. Furthermore, the predicted illuminance can be determined based on the indoor space's function. Alternatively, given the outdoor illuminance value, the current indoor illuminance (i.e., the predicted illuminance) without lights can be calculated.

[0078] In other examples, illuminance can also be predicted through algorithmic model software simulation or by obtaining existing publicly available data.

[0079] Furthermore, once outdoor illuminance and historical indoor illuminance have been acquired (e.g., through sensors), more accurate actual daylighting coefficient values ​​for different rooms at different times can be calculated and obtained. These values ​​can then be stored and applied in future usage scenarios via a storage device.

[0080] Combination Figure 4As shown in the embodiment of this application, another method for adjusting indoor brightness is provided. The brightness adjustment device in this method includes a curtain, and the method specifically includes:

[0081] S401: Obtain the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0082] S402: Determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0083] S403: When there are people indoors and the lights are on, the brightness range of the predicted illuminance is greater than or equal to the first threshold.

[0084] S404: Based on the correspondence between brightness range and control strategy, the target control strategy corresponding to the predicted illuminance is determined to be the light-off strategy.

[0085] S405: Calculate the indoor illuminance after the luminaire is turned off;

[0086] S406: If the indoor illuminance is greater than the second threshold after the lights are turned off, adjust the angle of the curtains to bring the indoor illuminance within the target illuminance range.

[0087] In the above embodiment, after the lights are turned off, to avoid insufficient indoor brightness due to inaccurate predictions, the indoor illuminance after the lights are turned off is acquired again. If the indoor illuminance after the lights are turned off is greater than or equal to the second threshold, it means that the indoor light is still too strong, and the brightness cannot be adjusted to a reasonable range by relying solely on the lights. At this time, the angle of the curtains is adjusted to ensure that the indoor illuminance is within the target illuminance range, thereby improving indoor comfort.

[0088] Combination Figure 5 As shown, this application provides another method for adjusting indoor brightness. The brightness adjustment device in this method includes a lamp, and the method specifically includes:

[0089] S501: Obtain the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0090] S502: Determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0091] S503: When there are people indoors and the lights are on, the brightness range of the predicted illuminance is less than the first threshold.

[0092] S504: Based on the correspondence between the brightness range and the control strategy, determine the target control strategy corresponding to the predicted illuminance as the adjustment strategy.

[0093] S505: Adjust the brightness of the lamps to ensure that the indoor illuminance is within the target illuminance range.

[0094] In the above embodiments, if the predicted illuminance is less than the first threshold, it means that the brightness may be too low if the lights are turned off. Therefore, an adjustment strategy is executed to adjust the brightness of the lamps so that the indoor illuminance is always kept within the target illuminance range, thus ensuring that the indoor brightness is reasonable.

[0095] Combination Figure 6 As shown, another method for adjusting indoor brightness provided in this application embodiment includes:

[0096] S601: Obtain the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0097] S602: Determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance.

[0098] S603: If there are people indoors and the lights are on, proceed to steps S604-S606; if there are people indoors and the lights are off, proceed to steps S607-S608.

[0099] S604: Obtain the brightness range within which the predicted illuminance is located;

[0100] S605: Determine the target control strategy corresponding to the predicted illuminance based on the correspondence between the luminance range and the control strategy;

[0101] S606: A brightness adjustment device that adjusts the brightness according to the target control strategy and the target illumination range.

[0102] S607: If the current indoor illuminance is greater than the second threshold, adjust the angle of the curtain to make the current indoor illuminance within the target illuminance range.

[0103] S608: If the current indoor illuminance is less than the first threshold, increase the brightness of the lamps so that the current indoor illuminance is within the target illuminance range.

[0104] In the above embodiments, when someone is indoors and the lights are off, if the indoor illuminance is greater than or equal to the second threshold, it indicates that the current brightness is too high, and curtains are needed to adjust the indoor brightness without turning on the lights, thus reducing energy consumption. Conversely, if the indoor illuminance is less than the first threshold, it indicates that the indoor brightness is too low, and the brightness of the lights can be used for illumination. Therefore, the brightness of the lights is increased to ensure the lighting effect of the smart lights.

[0105] Furthermore, when the illuminance is greater than the second threshold, there are people indoors, and the lights are already on, the method provided in any of the above embodiments further includes: issuing a prompt message to the user and adjusting the brightness of the lights according to the prompt message.

[0106] Specifically, a prompt message can be sent to ask the user whether they want to adjust the brightness to a suitable level for their eyes. If the user replies "yes", the brightness of the light fixture can be reduced. This can save energy while ensuring a good user experience and eye health.

[0107] The following is combined with Figures 7a-7c This illustration demonstrates a method for controlling the brightness of lighting fixtures in a practical application scenario, using a bathroom as an example. Figure 7a As shown, in the current scenario one, the room is empty and the lights are on, so the lights can be turned off directly, thus achieving the effect of saving energy.

[0108] Figure 7b The second scenario shown is a situation where there are people indoors, but the lights are off, and the process involves controlling the lighting fixtures based on different values ​​of indoor illuminance.

[0109] Figure 7c The current scenario three shown depicts an indoor space where people are present but the lights are on. The process involves controlling the lighting fixtures based on varying indoor illuminance values. In this case, it's necessary to further determine the predicted illuminance and control the lighting fixtures and / or curtains accordingly. In this embodiment, the first threshold is set to 150 l x, and the second threshold is set to 2000 l x.

[0110] Combination Figure 8 As shown, this application embodiment provides a device 800 for adjusting indoor brightness, including an acquisition module 801, a determination module 802, and a control module 803. Wherein,

[0111] The acquisition module 801 is configured to acquire the current indoor illuminance, outdoor illuminance, and historical indoor illuminance; the determination module 802 is configured to determine the predicted illuminance based on the current indoor illuminance, outdoor illuminance, and historical indoor illuminance; and the control module 803 is configured to control the brightness adjustment device based on the predicted illuminance and the target illuminance range to adjust the indoor brightness.

[0112] The device provided in this application first acquires the current indoor illuminance, outdoor illuminance, and historical indoor illuminance, and then predicts the illuminance to obtain the predicted illuminance. Since the predicted illuminance considers not only the current indoor and outdoor illuminance but also the historical indoor illuminance, it can effectively predict the indoor brightness that can be achieved after the lights are turned off. When the predicted illuminance is strong, it means that even if the brightness of the lights is reduced or the lights are turned off, a certain level of brightness can still be obtained. When the predicted illuminance is weak, it means that the brightness of the lights is needed to ensure the indoor brightness. Therefore, adjusting the brightness of the lights to the target illuminance range according to the predicted illuminance can achieve the effect of saving energy while ensuring indoor brightness.
