Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent lighting control, in particular to an LED lamp intelligent dimming method and system. BACKGROUND

[0002] At present, LED lamps have been widely used in various lighting scenes, and some high-end LED lamps have automatic dimming function. However, the dimming function of these lamps is mostly based on the intensity of ambient light, which is relatively simple. The intensity of ambient light is detected by a photosensitive sensor, and the brightness of the lamp is adjusted accordingly. However, this method ignores the influence of user's individual needs or use time on lighting, and the dimming strategy is single and not intelligent.

[0003] In view of the user's individual needs, some LED lamps are also provided with buttons or control interfaces for users to select and adjust the light. However, this design still needs to be adjusted manually, which is cumbersome for users and cannot provide better lighting effect for users. In addition, in the case of small changes in ambient light intensity, long-term exposure to a single light intensity can cause visual fatigue. Therefore, it is necessary to consider the use time factor to adjust the light intensity.

[0004] How to realize intelligent dimming control of LED lamps based on comprehensive consideration of environmental light intensity, user's individual lighting needs and use time, and provide better lighting effect for users. SUMMARY

[0005] In order to realize intelligent dimming control of LED lamps and provide better lighting effect for users, the present application provides an LED lamp intelligent dimming method and system.

[0006] In the first aspect, the present application provides an LED lamp intelligent dimming method, which comprises:

[0007] Real-time monitoring of ambient light intensity by photosensitive sensor installed on LED;

[0008] Real-time recording of LED light intensity during use of LED lamp, and marking of user-adjusted LED light intensity; the LED lamp is provided with LED light intensity adjustment button for user to adjust LED light intensity;

[0009] Analysis of user habit adjusted LED light intensity range in different preset ambient light intensity ranges; the user habit adjusted LED light intensity range is the range formed by user-adjusted LED light intensity with frequency greater than preset frequency in adjacent date period in different preset ambient light intensity ranges;

[0010] When it is monitored that the preset ambient light intensity range where the current ambient light intensity is located changes, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the LED light intensity range adjusted by the user habit corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, and before the next change of the preset ambient light intensity range where the current ambient light intensity is located, the automatic adjustment of the LED light intensity is completed once every interval of a preset time within the LED light intensity range adjusted by the user habit corresponding to the preset ambient light intensity range where the changed ambient light intensity is located.

[0011] By using the above scheme, the light intensity adjusted by the user when the ambient light intensity is in different preset ambient light intensity ranges is recorded, and the light intensity adjusted by the user habit is analyzed and obtained. Whenever the preset ambient light intensity range where the ambient light intensity is located changes, the light intensity adjusted by the user habit in the corresponding range is adjusted for the user, and the user does not need to adjust by himself / herself, which meets the individualized lighting needs of the user. In order to avoid the user being in a light intensity for a long time and causing eye fatigue, the automatic adjustment is completed within the light intensity range analyzed and obtained for a period of use time.

[0012] Preferably, the method further comprises:

[0013] When it is monitored that the preset ambient light intensity range where the current ambient light intensity is located changes, the LED light intensity used by the current recorded LED lamp is determined, and the minimum light intensity difference between the LED light intensity in the user use process recorded by the current record and the LED light intensity adjusted by the user habit corresponding to the preset ambient light intensity range where the changed ambient light intensity is located is calculated.

[0014] If the minimum light intensity difference calculated is greater than a preset light intensity difference, the first LED light intensity automatic adjustment after the change of the preset ambient light intensity range where the current ambient light intensity is located is completed within a first preset time range; otherwise, the first LED light intensity automatic adjustment after the change of the preset ambient light intensity range where the current ambient light intensity is located is completed within a second preset time range; the first preset time range is greater than the second preset time range.

[0015] By using the above scheme, considering that the light intensity changes too much before and after the adjustment, the rapid adjustment will cause the user's eyes to be uncomfortable, so the gap between the target light intensity adjustment range and the current recorded light intensity is calculated, and the adjustment is completed within a longer time when the gap is larger to achieve a more gentle adjustment.

[0016] Preferably, the method further comprises:

[0017] The expert-suggested LED light intensity range of the ambient light intensity in different preset ambient light intensity ranges is obtained.

[0018] The LED lamp is provided with an eye protection recommendation mode button. When a trigger instruction of the eye protection recommendation mode button is received and it is monitored that the preset ambient light intensity range in which the ambient light intensity is located changes, it is determined whether there is an intersection between the expert recommended LED light intensity range corresponding to the preset ambient light intensity range in which the ambient light intensity is located after the change and the LED light intensity range adjusted according to the user habit. If there is an intersection, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is located in the intersection of the expert recommended LED light intensity range corresponding to the preset ambient light intensity range in which the ambient light intensity is located after the change and the LED light intensity range adjusted according to the user habit. Otherwise, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is located in the expert recommended LED light intensity range corresponding to the preset ambient light intensity range in which the ambient light intensity is located after the change.

[0019] By using the above scheme, considering that different preset ambient light intensities correspond to an expert recommended light intensity range suitable for human eyes, the user habit demand is satisfied as much as possible and the light intensity adjustment is preferentially performed in the recommended LED light intensity range to protect the user eyes on the basis of the user selecting the eye protection mode.

[0020] Preferably, the LED lamp is further provided with scene selection buttons corresponding to a plurality of application scenes; wherein the application scenes include a reading scene, a leisure and entertainment scene and a working scene, and different LED light intensity ranges and color temperature ranges are set corresponding to each application scene.

[0021] When a trigger instruction corresponding to the reading scene selection button or the entertainment and leisure scene selection button or the working scene selection button is received, the LED light illumination color temperature range is automatically adjusted to be located in the corresponding set color temperature range and the LED light intensity allowed to be adjusted by the user is limited in the light intensity range set corresponding to the scene.

[0022] Based on the user selecting a specific application scene, the LED light intensity adjusted by the user in the selected specific scene during the use of the LED lamp is recorded and marked, and the LED light intensity range adjusted according to the user habit in different preset ambient light intensity ranges of the specific application scene is obtained by corresponding analysis. When it is monitored that the preset ambient light intensity range in which the current ambient light intensity is located changes, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is located in the LED light intensity range adjusted according to the user habit in the specific scene corresponding to the preset ambient light intensity range in which the ambient light intensity is located after the change.

[0023] By adopting the above scheme, considering that the light intensity and color temperature suitable for each scene are different when using the LED lamp in different application scenarios, the LED light color temperature adjustment and the LED light intensity range analysis and determination of the user habit adjustment are performed according to the user selection of the application scenario, and the adaptive adjustment of the light intensity in different application scenarios is performed.

[0024] Preferably, further comprising: within the feedback time after the change of the preset ambient light intensity range where the current ambient light intensity is located is monitored and the automatic adjustment of the LED light intensity is completed, judging whether the recorded LED light intensity is changed and the user self-adjusted LED light intensity is recorded;

[0025] If the recorded LED light intensity is changed and the user self-adjusted LED light intensity is recorded, it is further judged whether the user self-adjusted LED light intensity is within the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located within the feedback time;

[0026] If yes, the user self-adjusted LED light intensity is marked as a priority LED light intensity adjustment target; and the next time the change of the preset ambient light intensity range where the current ambient light intensity is located is monitored and the changed ambient light intensity is located in the same preset ambient light intensity range as the changed ambient light intensity corresponding to the feedback time before, the LED light intensity is automatically adjusted to the priority LED light intensity adjustment target.

[0027] By adopting the above scheme, considering that the user self-adjusted the light intensity again within the self-adjusted light intensity range, which indicates that the user self-adjusted light intensity is the most suitable light intensity for the user, the light intensity is marked as a priority light intensity adjustment target, and the self-adjustment is performed according to the priority light intensity adjustment target when the same light intensity change occurs next time.

[0028] Preferably, further comprising:

[0029] During the use of the LED lamp, the user voice adjustment LED light intensity instruction is received in real time, and the LED light intensity adjustment is completed in real time according to the received user voice adjustment LED light intensity instruction;

[0030] Within the feedback period after the real-time completion of the LED light intensity adjustment, if the user voice adjustment LED light intensity instruction is not received, the LED light intensity after the recent real-time completion of the LED light intensity adjustment is taken as the user self-adjusted LED light intensity and is marked.

[0031] By adopting the above scheme, the recorded and marked LED light intensity adjusted by the user also includes the adjusted LED light intensity obtained by the user based on voice self-adjustment, so as to more comprehensively analyze the user habit adjusted LED light intensity.

[0032] Preferably, the number of the photosensitive sensors mounted on the LED is multiple, and the average of the multiple real-time monitored ambient light intensities is taken as the final real-time monitored ambient light intensity.

[0033] By adopting the above scheme, the multiple photosensitive sensors are used to detect the more accurate ambient light intensity by taking the average of the collected ambient light intensities.

[0034] In a second aspect, the present application provides an LED lamp intelligent dimming system, comprising:

[0035] An ambient light intensity acquisition module is configured to use the photosensitive sensor mounted on the LED to monitor the ambient light intensity in real time.

[0036] An LED light intensity acquisition module is configured to record the LED light intensity in the use process of the LED lamp in real time, and mark the LED light intensity adjusted by the user; the LED lamp is provided with an LED light intensity adjustment button or an LED light intensity adjustment control interface for the user to adjust the LED light intensity.

[0037] A user habit light intensity acquisition module is configured to analyze and obtain the user habit adjusted LED light intensity range in different preset ambient light intensity ranges; the user habit adjusted LED light intensity range is formed by the user self-adjusted LED light intensity with a frequency greater than a preset frequency in adjacent date periods in different preset ambient light intensity ranges.

[0038] An LED light intensity automatic adjustment module is configured to automatically adjust the LED light intensity when the preset ambient light intensity range of the current ambient light intensity changes, so that the adjusted LED light intensity is in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range of the changed ambient light intensity, and every interval of a preset time before the preset ambient light intensity range of the current ambient light intensity changes next time, the automatic adjustment of the LED light intensity is completed in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range of the changed ambient light intensity.

[0039] By adopting the above scheme, the intelligent dimming control of the LED lamp is realized based on the comprehensive consideration of the ambient light intensity, the user personalized lighting demand and the use time factor, and better lighting effect is provided for the user.

[0040] In a third aspect, the present application provides a computer readable storage medium, comprising a stored computer program, wherein the computer program, when executed, controls a device in which the computer readable storage medium is located to perform the method described above.

[0041] In a fourth aspect, the present application provides a computer device, comprising a memory, a processor and a program stored in the memory and executable by the processor, wherein the program, when executed by the processor, implements the steps of the method described above.

[0042] In summary, the present application has the following advantages:

[0043] 1. The present application comprehensively considers the ambient light intensity, the user's individual lighting needs and the use time factor, records and analyzes the user's habit-adjusted LED light intensity range under the condition that the current ambient light intensity is in different preset ambient light intensity ranges, adjusts the LED light intensity range according to the user's habits, and automatically adjusts multiple times according to the preset use time, thereby achieving intelligent dimming control of the LED lamp and providing better lighting effect for the user;

[0044] 2.

[0047] Figure 2 A structural schematic diagram of the LED lamp intelligent dimming system described in the specific embodiment. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0049] As shown in Figure 1 The present application discloses an LED lamp intelligent dimming method, and the specific steps are as follows:

[0050] S1, real-time monitoring of ambient light intensity by using photosensitive sensors installed on the LED lamp.

[0051] Specifically, the number of photosensitive sensors installed on the LED lamp is multiple, and the multiple photosensitive sensors are uniformly installed in the form of an array on the area of the LED lamp away from the light source, so as to avoid the influence of the light intensity of the LED on the collection of the ambient light intensity as much as possible.

[0052] The mean value of the ambient light intensity monitored by the multiple photosensitive sensors is calculated, and the mean value is taken as the final real-time monitoring ambient light intensity.

[0053] S2, real-time recording of the LED light intensity during the use of the LED lamp, and marking the LED light intensity adjusted by the user.

[0054] Specifically, the LED light intensity during the entire use of the LED lamp from starting to closing is recorded in real time, including: the initial LED light intensity when the LED lamp system is set to start, the corresponding LED light intensity after the user automatically adjusts the LED light intensity, i.e. the LED light intensity adjusted by the user, and the LED light intensity during the use when a sudden situation change is encountered, etc.

[0055] Among them, the LED lamp is provided with an LED light intensity adjustment button or an LED light intensity adjustment control interface for the user to adjust the LED light intensity; once the light intensity adjustment button trigger instruction generated by the user operating the LED light intensity adjustment button or the light intensity adjustment instruction generated by the user operating the LED light intensity adjustment control interface is received, and the LED light intensity is adjusted, the LED light intensity adjusted by the user is marked.

[0056] In addition, some lamps also provide the user to adjust the LED light intensity by voice. During the use of the LED lamp, the user's voice adjustment LED light intensity instruction is received in real time, such as: brightening a little or dimming a little, and the LED light intensity is adjusted in real time according to the received user voice adjustment LED light intensity instruction, such as: receiving the instruction to brighten a little, increasing the LED light intensity according to the preset adjustment LED light intensity, and receiving the instruction to dim a little, decreasing the LED light intensity according to the preset adjustment LED light intensity.

[0057] Within the feedback time after the LED light intensity is adjusted in real time, no user voice adjustment LED light intensity instruction is received, and the feedback time is the preset time for the user to continue adjusting the LED brightness; the LED light intensity after the LED light intensity is adjusted in real time is taken as the LED light intensity adjusted by the user and is marked.

[0058] S3, analyze the obtained ambient light intensity to obtain the user habit adjusted LED light intensity range in different preset ambient light intensity ranges.

[0059] Specifically, the ambient light intensity is divided into different ranges according to a preset interval light intensity (such as 100 lux), and different preset ambient light intensity ranges are obtained. For each preset ambient light intensity range, the user self-adjusted LED light intensity that appears more than a preset frequency in the adjacent date period (such as in the past month) when the ambient light intensity is in the preset ambient light intensity range is counted, and the user habit adjusted LED light intensity range is generated from the counted user self-adjusted LED light intensity, and the user habit adjusted LED light intensity range corresponding to each preset ambient light intensity range is obtained.

[0060] S4, when the change of the preset ambient light intensity range where the current ambient light intensity is located is monitored, the LED light intensity is automatically adjusted.

[0061] When the change of the preset ambient light intensity range where the ambient light intensity is located is monitored, such as the range where the ambient light intensity is located at the current time changes from the first preset ambient light intensity range to the second preset ambient light intensity range; according to the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, the automatic adjustment of the LED light intensity is completed, so that the adjusted LED light intensity is in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, that is, the adjusted LED light intensity is in the user habit adjusted LED light intensity range corresponding to the second preset ambient light intensity range.

[0062] At the same time, in order to avoid being in the same LED light intensity range in a preset ambient light intensity range all the time, causing user visual fatigue, before the next change of the preset ambient light intensity range where the current ambient light intensity is located, the automatic adjustment of the LED light intensity is completed every interval a preset time (unit: minute) in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located.

[0063] Each time the automatic adjustment of the LED light intensity is based on the last adjusted LED light intensity, and the light intensity in the corresponding user habit adjusted LED light intensity range is adjusted in order from large to small or from small to large or from large to small, from small to large, and the adjustment amplitude (such as 10 lux) is much smaller than the preset light intensity difference, which can be selected as 1 / N times of the preset light intensity difference.

[0064] In one embodiment, when the current ambient light intensity is detected to change from one preset ambient light intensity range to another, the initial automatic adjustment process is performed to avoid rapid adjustment of the LED light intensity to a large light intensity, which can result in poor user experience. The method further comprises:

[0065] When the current ambient light intensity is detected to change from one preset ambient light intensity range to another, the LED light intensity recorded during the current use of the LED lamp is determined.

[0066] The minimum light intensity difference between the LED light intensity recorded during the current use of the LED lamp and the LED light intensity range adjusted according to the user's habits corresponding to the changed ambient light intensity range is calculated.

[0067] If the calculated minimum light intensity difference is greater than a preset light intensity difference, the initial LED light intensity automatic adjustment is completed within a first preset time range, i.e., the initial LED light intensity automatic adjustment is performed after the current ambient light intensity is detected to change from one preset ambient light intensity range to another. Otherwise, the initial LED light intensity automatic adjustment is completed within a second preset time range, i.e., the initial LED light intensity automatic adjustment is performed after the current ambient light intensity is detected to change from one preset ambient light intensity range to another. The first preset time range is greater than the second preset time range.

[0068] In one embodiment, in order to further improve the user's experience of using the LED lamp, the LED light intensity adjustment is considered to be in line with the user's habits and the eye health, and the method further comprises:

[0069] The expert-recommended LED light intensity range in different preset ambient light intensity ranges is obtained. For example, in the first preset ambient light intensity range (low light environment), the expert-recommended LED light intensity range is 100-200 lux, in the second preset ambient light intensity range (medium light environment), the expert-recommended LED light intensity range is 300-500 lux, and in the third preset ambient light intensity range (strong light environment), the expert-recommended LED light intensity range is 500-800 lux.

[0070] The LED lamp is provided with an eye protection recommendation mode button. When the eye protection recommendation mode button trigger instruction is received (i.e., the user receives the LED light intensity adjustment in line with the eye health) and the current ambient light intensity is detected to change from one preset ambient light intensity range to another, it is determined whether there is an intersection between the expert-recommended LED light intensity range corresponding to the changed ambient light intensity range and the LED light intensity range adjusted according to the user's habits.

[0071] If there is an intersection, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the intersection of the expert recommended LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located and the LED light intensity range adjusted according to the user's habits, that is, the adjusted LED light intensity is as consistent as possible with the user's habits and the eye health;

[0072] Otherwise, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the expert recommended LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, that is, the adjusted LED light intensity is prioritized to be consistent with eye health.

[0073] In one specific embodiment, in addition to the conventional lighting effect, in order to improve the user's experience, different application environments are set, and different LED light intensity ranges are set for each application environment; the method further comprises:

[0074] The LED lamp is also provided with scene selection buttons corresponding to a plurality of application scenarios; wherein the application scenarios include: reading scenario, leisure and entertainment scenario, and working scenario, and different LED light intensity ranges and color temperature ranges are set for each specific application scenario; for example, in the reading scenario, a warm color temperature is generally set, and in the leisure and entertainment scenario, a cold color temperature is generally set.

[0075] When receiving a trigger instruction corresponding to the reading scenario selection button or the entertainment and leisure scenario selection button or the working scenario selection button (the above instruction is generated when the user triggers the corresponding button), the LED light color temperature range is automatically adjusted to the corresponding set color temperature range, and the LED light intensity allowed to be adjusted by the user is limited to the light intensity range set for the corresponding scenario;

[0076] Based on the user selecting a specific application scenario, the LED light intensity adjusted by the user during the use of the LED lamp in the selected specific scenario is recorded and marked, and the LED light intensity range adjusted by the user according to habits in the specific application scenario under different preset ambient light intensity ranges is obtained through corresponding analysis; for example, the user triggers the reading scenario selection button, and the LED light intensity adjusted by the user during the use of the LED lamp in the reading scenario is recorded, and the LED light intensity range adjusted by the user according to habits in the reading scenario under different preset ambient light intensity ranges is obtained through corresponding statistical analysis.

[0077] When it is monitored that the preset ambient light intensity range where the current ambient light intensity is located changes, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the LED light intensity range adjusted by the user according to habits in the specific scenario corresponding to the preset ambient light intensity range where the changed ambient light intensity is located.

[0078] One specific embodiment, considering that the user still adjusts the process by himself after the automatic adjustment is completed according to the user habit, further combining the user self-adjustment of the LED light intensity, perfecting the automatic adjustment of the LED light intensity, more adapting to the user demand, improving the user experience; the method further comprises:

[0079] Within the feedback time (such as 3 minutes) after monitoring that the current ambient light intensity range changes and completing the automatic adjustment of the LED light intensity, it is judged whether the recorded LED light intensity changes and the user self-adjusted LED light intensity with a mark is recorded;

[0080] If the recorded LED light intensity changes and the user self-adjusted LED light intensity with a mark is recorded, it means that the user does not turn off the light and the user still exists adjustment after the automatic adjustment, and the current adjusted light intensity does not reach the user satisfaction, then it is judged whether the user self-adjusted LED light intensity is in the user habit adjusted LED light intensity range corresponding to the changed ambient light intensity range within the feedback time;

[0081] If it is, mark the user self-adjusted LED light intensity as the priority LED light intensity adjustment target; for example: at 22:10, it is monitored that the ambient light intensity is in the second preset ambient light intensity range changing to the first preset ambient light intensity range, then the corresponding self-adjusted light intensity is 100 lux, at 22:11, the user self-adjusted LED light intensity with a mark is recorded as 120 lux, the user self-adjusted LED light intensity is still in the user habit adjusted LED light intensity range (100-130 lux) corresponding to the self-adjustment at 22:10, then the user self-adjusted LED light intensity 120 lux is marked as the priority LED light intensity adjustment target;

[0082] When the next time the current ambient light intensity range changes and the changed ambient light intensity is in the same preset ambient light intensity range as the corresponding changed ambient light intensity before the feedback time, the LED light intensity is automatically adjusted to the priority LED light intensity adjustment target; that is, when the next time the ambient light intensity is in the second preset ambient light intensity range changing to the first preset ambient light intensity range, the LED light intensity is automatically adjusted to 120 lux.

[0083] As shown in Figure 2 The present application provides an LED lamp intelligent dimming system, which comprises:

[0084] The ambient light intensity acquisition module 101 is used for monitoring the ambient light intensity in real time by using the photosensitive sensor installed on the LED.

[0085] The LED light intensity acquisition module 102 is configured to record the LED light intensity in real time during use of the LED lamp and mark the LED light intensity adjusted by the user. The LED lamp is provided with an LED light intensity adjustment button for the user to adjust the LED light intensity.

[0086] The user habit light intensity acquisition module 103 is configured to analyze and obtain the user habit adjusted LED light intensity range in different preset ambient light intensity ranges.

[0087] The LED light intensity automatic adjustment module 104 is configured to automatically adjust the LED light intensity when a change in the preset ambient light intensity range where the current ambient light intensity is located is monitored, so that the adjusted LED light intensity is in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, and before the next change in the preset ambient light intensity range where the current ambient light intensity is located is monitored, the LED light intensity is automatically adjusted once in the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located every interval of a preset time.

[0088] In one embodiment, the LED light intensity automatic adjustment module 104 is further configured to determine the currently recorded LED light intensity of the LED lamp during use when a change in the preset ambient light intensity range where the current ambient light intensity is located is monitored, calculate the minimum light intensity difference between the currently recorded LED light intensity during use of the user and the user habit adjusted LED light intensity range corresponding to the preset ambient light intensity range where the changed ambient light intensity is located, and if the calculated minimum light intensity difference is greater than a preset light intensity difference, the first LED light intensity automatic adjustment after the change in the preset ambient light intensity range where the current ambient light intensity is located is monitored is completed in a first preset time range; otherwise, the first LED light intensity automatic adjustment after the change in the preset ambient light intensity range where the current ambient light intensity is located is monitored is completed in a second preset time range; and the first preset time range is greater than the second preset time range.

[0089] In one embodiment, the LED light intensity automatic adjustment module 104 is further configured to obtain a range of LED light intensity recommended by an expert for different preset ambient light intensity ranges; the LED lamp is provided with an eye protection recommendation mode button, and when a trigger instruction of the eye protection recommendation mode button is received and a change in the preset ambient light intensity range in which the previous ambient light intensity is located is detected, it is determined whether there is an intersection between the range of LED light intensity recommended by the expert corresponding to the preset ambient light intensity range in which the changed ambient light intensity is located and the range of LED light intensity adjusted by the user habit; if there is an intersection, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the intersection of the range of LED light intensity recommended by the expert corresponding to the preset ambient light intensity range in which the changed ambient light intensity is located and the range of LED light intensity adjusted by the user habit; otherwise, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the range of LED light intensity recommended by the expert corresponding to the preset ambient light intensity range in which the changed ambient light intensity is located.

[0090] In one embodiment, the LED light intensity automatic adjustment module 104 is further configured to set a plurality of scene selection buttons corresponding to different application scenarios on the LED lamp; wherein the application scenarios include reading scenario, leisure and entertainment scenario, and working scenario, and different LED light intensity range and color temperature range are set for each application scenario; when a trigger instruction corresponding to the reading scenario selection button or the entertainment and leisure scenario selection button or the working scenario selection button is received, the LED light color temperature range is automatically adjusted to the corresponding set color temperature range, and the LED light intensity is limited within the light intensity range set for the corresponding scenario; based on the user selecting a specific application scenario, the LED light intensity adjusted by the user during the use of the LED lamp in the selected specific scenario is recorded and marked, and the range of LED light intensity adjusted by the user habit in the specific application scenario for different preset ambient light intensity ranges is obtained by corresponding analysis; when a change in the preset ambient light intensity range in which the current ambient light intensity is located is detected, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the range of LED light intensity adjusted by the user habit in the specific scenario corresponding to the preset ambient light intensity range in which the changed ambient light intensity is located.

A method for intelligent dimming of LED lamps, characterized in that, include: Ambient light intensity is monitored in real time using a photosensitive sensor mounted on an LED; Records the LED light intensity in real time during the use of LED lights and marks the LED light intensity adjusted by the user. The LED lamp is equipped with an LED light intensity adjustment button for users to adjust the LED light intensity themselves; The analysis yields the range of LED light intensity that users habitually adjust within different preset ambient light intensity ranges. The range of LED light intensity that users habitually adjust is the range formed by user-adjusted LED light intensity when the frequency of ambient light intensity exceeds the preset frequency within a nearby date period, within different preset ambient light intensity ranges. When a change in the current ambient light intensity within a preset range is detected, the LED light intensity is automatically adjusted so that the adjusted LED light intensity falls within the user-preferred range corresponding to the changed ambient light intensity. Furthermore, before the next change in the current ambient light intensity within the preset range is detected, the LED light intensity is automatically adjusted once every preset time interval within the user-preferred range corresponding to the changed ambient light intensity. This also includes: When a change is detected in the preset ambient light intensity range of the current ambient light intensity, the LED light intensity of the currently recorded LED lamps during use is determined, and the minimum light intensity difference between the LED light intensity of the currently recorded user usage process and the LED light intensity range adjusted by the user according to their habits corresponding to the preset ambient light intensity range of the changed ambient light intensity is calculated. If the calculated minimum light intensity difference is greater than the preset light intensity difference, then the initial automatic adjustment of LED light intensity is completed within the first preset time range after a change in the current ambient light intensity within the preset ambient light intensity range is detected; otherwise, the initial automatic adjustment of LED light intensity is completed within the second preset time range after a change in the current ambient light intensity within the preset ambient light intensity range is detected; the first preset time range is greater than the second preset time range; further includes: Obtain the expert-recommended range of LED light intensity from different preset ambient light intensity ranges; The LED lamp is equipped with an eye protection recommended mode button. Upon receiving a trigger command from the eye protection recommended mode button and detecting a change in the preset ambient light intensity range, it determines whether there is an overlap between the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range after the change and the user's habitually adjusted LED light intensity range. If there is an overlap, the LED light intensity is automatically adjusted so that the adjusted LED light intensity falls within the overlap between the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range after the change and the user's habitually adjusted LED light intensity range. Otherwise, the LED light intensity is automatically adjusted so that the adjusted LED light intensity falls within the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range after the change. The LED lamp is also equipped with scene selection buttons for various application scenarios. The application scenarios include: reading scenarios, leisure and entertainment scenarios, and work scenarios, and each application scenario corresponds to a different LED light intensity range and color temperature range. When a trigger command is received from the reading scene selection button, entertainment and leisure scene selection button, or work scene selection button, the LED light color temperature range is automatically adjusted to be within the corresponding set color temperature range, and the LED light intensity that the user can adjust is limited to the light intensity range set for the corresponding scene. Based on the user's selection of a specific application scenario, the system records and marks the LED light intensity adjusted by the user during the use of LED lights in that specific scenario. Correspondingly, it analyzes and obtains the range of LED light intensity adjusted by the user within different preset ambient light intensity ranges for that specific application scenario. When a change in the preset ambient light intensity range is detected, the system automatically adjusts the LED light intensity so that the adjusted LED light intensity is within the range of the user's habitually adjusted LED light intensity for that specific scenario. Furthermore, within the feedback time after detecting a change in the preset ambient light intensity range and completing the automatic adjustment of the LED light intensity, it determines whether the recorded LED light intensity has changed and whether the user-adjusted LED light intensity is recorded and marked. If the recorded LED light intensity changes and the user-adjusted LED light intensity is marked, then it is further determined whether the user-adjusted LED light intensity is within the range of the user's habitually adjusted LED light intensity corresponding to the preset ambient light intensity range after the change in ambient light intensity within the feedback time. If so, the user-adjusted LED light intensity is marked as the priority LED light intensity adjustment target; the next time the current ambient light intensity changes within the preset ambient light intensity range and the changed ambient light intensity is within the same preset ambient light intensity range as the changed ambient light intensity before the feedback time, the LED light intensity is automatically adjusted to the priority LED light intensity adjustment target.

2. The intelligent dimming method for LED lamps according to claim 1, characterized in that, Also includes: During the use of LED lighting fixtures, the system receives user voice commands to adjust the LED light intensity in real time and completes the LED light intensity adjustment in real time based on the received user voice commands. If no further user voice commands to adjust LED light intensity are received during the feedback period after real-time LED light intensity adjustment is completed, the LED light intensity after the most recent real-time LED light intensity adjustment will be used as the user's adjusted LED light intensity and marked accordingly.

3. The intelligent dimming method for LED lamps according to claim 1, characterized in that, The number of photosensitive sensors installed on the LED is multiple, and the average value of the ambient light intensity monitored in real time is taken as the final real-time ambient light intensity.

4. An intelligent dimming system for LED lighting fixtures, characterized in that, include: An ambient light intensity acquisition module is used to monitor ambient light intensity in real time using a photosensitive sensor installed on an LED. The LED light intensity acquisition module is used to record the LED light intensity in real time during the use of LED lamps and mark the LED light intensity adjusted by the user. The LED lamp is equipped with an LED light intensity adjustment button for users to adjust the LED light intensity themselves; The user-customed light intensity acquisition module is used to analyze and obtain the range of LED light intensity that users habitually adjust within different preset ambient light intensity ranges; the range of LED light intensity that users habitually adjust is: the range of LED light intensity formed by users adjusting themselves within a period of time adjacent to a preset date when the ambient light intensity occurs at a frequency greater than a preset frequency within different preset ambient light intensity ranges; The LED light intensity automatic adjustment module is used to automatically adjust the LED light intensity when it detects a change in the current ambient light intensity within a preset ambient light intensity range. This ensures the adjusted LED light intensity falls within the user-preferred range of LED light intensity adjustment that corresponds to the changed ambient light intensity. Before detecting another change in the current ambient light intensity within the preset range, the module performs an automatic adjustment of the LED light intensity at preset time intervals within the user-preferred range of LED light intensity adjustment that corresponds to the changed ambient light intensity. Furthermore, when a change in the current ambient light intensity within the preset range is detected, the module determines the currently recorded LED light intensity during use and calculates the minimum light intensity difference between the currently recorded LED light intensity during user use and the user-preferred range of LED light intensity adjustment that corresponds to the changed ambient light intensity. If the calculated minimum light intensity difference is greater than the preset light intensity difference, then the first automatic adjustment of LED light intensity will be completed within the first preset time range after the current ambient light intensity is detected to have changed within the preset ambient light intensity range. Otherwise, within the second preset time range, the initial automatic adjustment of LED light intensity is completed after a change in the preset ambient light intensity range of the current ambient light intensity is detected; the first preset time range is longer than the second preset time range; it is also used to obtain the expert-recommended LED light intensity range for different preset ambient light intensity ranges; the LED lamp is equipped with an eye protection recommendation mode button, and when it receives the trigger command of the eye protection recommendation mode button and detects a change in the preset ambient light intensity range of the previous ambient light intensity, it determines whether there is an intersection between the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range of the changed ambient light intensity and the LED light intensity range that the user is accustomed to adjusting; if there is an intersection, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the intersection of the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range of the changed ambient light intensity and the LED light intensity range that the user is accustomed to adjusting; otherwise, the LED light intensity is automatically adjusted so that the adjusted LED light intensity is within the expert-recommended LED light intensity range corresponding to the preset ambient light intensity range of the changed ambient light intensity. The LED lighting fixture is also equipped with scene selection buttons corresponding to various application scenarios. These application scenarios include reading, leisure / entertainment, and work scenarios, with each scenario having a corresponding LED light intensity range and color temperature range. Upon receiving a trigger command from the reading, leisure / entertainment, or work scenario selection button, the LED light color temperature range is automatically adjusted to the corresponding set color temperature range, and the user-adjustable LED light intensity is limited to the light intensity range set for the corresponding scenario. Based on the user's selection of a specific application scenario, the LED light intensity adjusted by the user during use is recorded and marked. Analysis is then performed to obtain the user-adjusted LED light intensity range within different preset ambient light intensity ranges for that specific application scenario. When a change in the current ambient light intensity's preset ambient light intensity range is detected, the LED light intensity is automatically adjusted so that the adjusted LED light intensity falls within the user-adjusted LED light intensity range for the specific scenario corresponding to the changed ambient light intensity's preset ambient light intensity range. It is also used to determine, within the feedback time after detecting a change in the current ambient light intensity within the preset ambient light intensity range and completing the automatic adjustment of LED light intensity, whether the recorded LED light intensity has changed and whether the user-adjusted LED light intensity is recorded and marked; if the recorded LED light intensity has changed and the user-adjusted LED light intensity is recorded and marked, then it continues to determine whether the user-adjusted LED light intensity is within the user's habitually adjusted LED light intensity range corresponding to the preset ambient light intensity range after the change; if it is, then the user-adjusted LED light intensity is marked as the priority LED light intensity adjustment target; the next time a change in the current ambient light intensity within the preset ambient light intensity range is detected and the changed ambient light intensity is within the same preset ambient light intensity range as the changed ambient light intensity before the feedback time, the LED light intensity is automatically adjusted to the priority LED light intensity adjustment target.
