Description

Technical Field

[0001] This invention relates to the field of smart home and smart lighting technology, specifically to a control method and system for a smart bedside lamp. Background Technology

[0002] With the popularization of smart home technology, users are increasingly using mobile devices in low-light environments at night. The difference in brightness between the screen light and the ambient light in dark environments can easily cause visual fatigue, requiring bedside lamps to provide auxiliary lighting. Currently, bedside lamps and related lighting control solutions disclosed in the market and existing patent literature have the following shortcomings: 1. Insufficient ease of operation: Traditional bedside lamps use contact switches and brightness adjustment structures, making it difficult for users to quickly locate the operating area in dark environments. The operation process is prone to producing noise or changes in light, disturbing people resting in the same space, and cannot achieve seamless lighting control.

[0003] 2. Insufficient behavior recognition accuracy and high false trigger rate. Existing lighting solutions using photosensitive and sound-controlled triggers can only achieve trigger control based on a single-dimensional environmental parameter. They cannot distinguish between the target behavior of users using mobile terminals at night and non-target behaviors such as changes in ambient light and people moving around, which easily leads to false triggers and missed triggers. Some solutions using simple logic combinations of multiple sensors can only achieve AND / OR judgments under fixed conditions, which cannot cope with complex user scenarios and have weak anti-interference capabilities.

[0004] 3. There are privacy and security risks. Some lighting solutions with behavior recognition functions use cameras to collect user image data to judge behavior, which poses a risk of user privacy leakage. Even if local data processing is used, it cannot eliminate users' concerns about image collection devices in the bedroom environment. At the same time, the appearance of related collection components is not obviously distinguishable from camera devices, which further exacerbates users' privacy concerns.

[0005] 4. The light scattering can easily disturb others' rest. Most existing bedside lamps adopt a symmetrical light distribution design, which has a wide light scattering range and can easily illuminate areas that are not properly lit, disturbing other people resting in the same space. At the same time, the color temperature of the light source used in most solutions does not meet the visual needs of dark environments at night, which can easily exacerbate users' visual fatigue.

[0006] 5. The working mode switching logic is rigid, resulting in a poor user experience. The existing solution only sets up basic automatic and manual working modes, without a low-power sleep mode for use in dark environments, and cannot balance trigger response speed and device standby power consumption. At the same time, there is no smooth transition logic between automatic and manual modes. After the user intervenes manually, the automatic mode cannot be restored normally, resulting in a disjointed experience.

[0007] Therefore, there is an urgent need for a bedside lamp control solution that can accurately identify user mobile phone usage behavior, ensure privacy and security, provide light-friendly lighting, and allow for smooth mode switching. Summary of the Invention

[0008] The purpose of this invention is to provide a control method and system for an intelligent bedside lamp, which solves the problems of low behavior recognition accuracy, high false trigger rate, significant privacy and security risks, light scattering that interferes with others, and rigid mode switching logic in the prior art, and achieves highly accurate, highly reliable, privacy-secure, and smooth bedside lamp control.

[0009] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A method for controlling a smart bedside lamp includes the following steps: Step S1, Multi-source sensing data acquisition: An ambient light sensor is used to collect ambient light brightness values; a proximity sensor is used to collect distance information or proximity signals between the user and the sensor; Step S2, Environmental Status Judgment: Compare the brightness value collected by the ambient light sensor with the preset dark environment threshold. When the brightness value is lower than the preset dark environment threshold, enter the dark standby state. Step S3, Trigger Judgment: In dark standby mode, if the following first and second conditions are met simultaneously, it is determined that the user is using the phone: First condition: The ambient light sensor detects a significant increase in brightness value exceeding a preset incremental threshold within a short period of time, and this increase remains stable for a first preset duration. Second condition: The proximity sensor detects the presence of an object within its effective detection range; Step S4, Lighting Control: When the determination condition of step S3 is met, the lighting module is controlled to turn on to the first brightness level in a smooth and gradual manner; when the first condition and / or the second condition is no longer met and continues for a second preset time, the lighting module is controlled to turn off in a smooth and gradual manner. Step S5, Manual Mode Switching: In any state, when a non-contact trigger operation is received from the user, the system enters manual mode; in manual mode, each non-contact trigger operation causes the light to cycle through the first brightness level, the second brightness level, and the off state in sequence; when the light is switched to the off state, the system automatically returns to step S1.

[0010] Furthermore, the lighting module outputs warm yellow light of 2700K–3000K and outputs the light in an asymmetrical light distribution manner, so that the light forms a high-brightness core area in the user-preset supplementary lighting area, and the light attenuates in a gradient from the core area to the surrounding area, suppressing the scattering of light to non-supplementary lighting areas.

[0011] Furthermore, the non-contact triggering operation is a non-contact sensing operation.

[0012] Furthermore, a wireless communication unit can also be provided. The wireless communication unit is used to receive the screen on / off signal or connection status signal of the mobile terminal, and participates in the triggering judgment of step S3 as an auxiliary criterion. When the wireless communication unit is not connected, the system still operates independently.

[0013] Furthermore, a control system for an intelligent bedside lamp includes an ambient light sensor, a proximity sensor, a non-contact interaction unit, a control module, and a lighting module. The ambient light sensor is used to collect ambient light brightness values; the proximity sensor is used to collect user proximity signals; the non-contact interaction unit is used to receive non-contact trigger operations from the user; the control module is connected to the ambient light sensor, the proximity sensor, the non-contact interaction unit, and the lighting module, and the lighting module is used to output light according to the instructions of the control module.

[0014] Furthermore, the lighting module includes an LED light source array of 2700K-3000K, a constant current drive circuit, and a freeform microstructure lens. The freeform microstructure lens enables the light to form illuminance at the first brightness level and the second brightness level in the user-preset supplementary lighting area. The illuminance value of the non-supplementary lighting area is lower than the minimum illuminance of the supplementary lighting area. The light intensity decreases in a gradient from the core area of ​​the supplementary lighting area to the periphery.

[0015] Furthermore, the non-contact interaction unit is an array of sensing electrodes, with the sensing area of ​​the capacitive sensing electrode located on the operating surface of the bedside lamp, and the surface of the sensing area covered with an anti-interference shielding layer.

[0016] Furthermore, the ambient light sensor and the infrared proximity sensor have a photosensitive window with a structure combining an array of slits and a dot matrix, the surface of the photosensitive window is covered with a gradient dark filter, and the outer surface of the sensor has raised and recessed functional markings.

[0017] The advantages of this invention compared to the prior art are: 1. This invention uses the fusion of ambient light sensor and proximity sensor to determine whether the brightness value exceeds a preset incremental threshold for a short period of time and remains stable for a certain period of time in the dark standby state, while the presence of an object in the effective detection range is used as a dual trigger condition. This achieves dual-dimensional cross-verification, effectively filtering out non-target behaviors such as instantaneous fluctuations in ambient light and people walking, and reducing the probability of false triggering.

[0018] 2. This invention eliminates the ability to acquire images from the source of data collection by using only ambient light sensors and proximity sensors without imaging capabilities, along with a privacy-friendly appearance design such as an array of slits and dot matrix structures for the light-sensing window, a gradient dark filter, and embossed functional markings on the outer shell. This eliminates the risk of privacy leaks to users in their bedrooms.

[0019] 3. This invention employs an asymmetric light distribution optical system, which enables light to form a high-brightness core area in the user-preset supplementary lighting area and then gradually decrease towards the periphery. Combined with a 2700K-3000K warm yellow light source, it achieves a soft lighting effect that does not disturb others resting in the same space.

[0020] 4. This invention establishes a seamless connection logic between automatic supplemental lighting mode and manual mode: after receiving a non-contact sensor trigger operation in any state, it switches to manual mode. In manual mode, each trigger causes the light to cycle between the first brightness level, the second brightness level, and the off state in sequence. After the light is off, the system automatically resumes environmental monitoring and automatic trigger judgment, achieving a smooth experience of automatic resumption of intelligent monitoring after the user manually turns off the light.

[0021] 5. This invention adopts pure rule-based logic control, relying only on threshold comparison, dual-condition judgment and timing logic of ambient light sensor and proximity sensor, without the need for any complex model or cloud computing, and achieves stable operation on low-cost microcontroller with extremely low power consumption.

The illustrative embodiments and descriptions of this application are used to explain the application and do not constitute an undue limitation of the application.

[0023] In the attached diagram: Figure 1 This is a flowchart of a control method for a smart bedside lamp in Example 1.

[0024] Figure 2 This is a system interaction diagram of a smart bedside lamp control system in Example 1. Detailed Implementation

[0025] The following detailed description of the embodiments is used to exemplify the principles of this application, but should not be used to limit the scope of this application. That is, the control method and system for a smart bedside lamp in this application are not limited to the described embodiments.

[0026] The present invention will be further described below with reference to embodiments.

[0027] like Figure 1 As shown, a control method for a smart bedside lamp includes the following steps: Step S1, Multi-source sensing data acquisition: Use an ambient light sensor to collect ambient light brightness values; use a proximity sensor to collect distance information or proximity signals between the user and the sensor.

[0028] Ambient light sensor: In one embodiment, the ambient light sensor is a VEML7700 sensor. This sensor is capable of detecting ambient light illuminance values ​​and changes therein with high sensitivity.

[0029] Proximity sensor: In one embodiment, the proximity sensor is an infrared proximity sensor, such as the VCNL4040 sensor. This sensor determines the presence of an object within its effective detection range by emitting infrared light and detecting the intensity of the reflected light.

[0030] It is understood that proximity sensors are not limited to infrared types. In other embodiments, the proximity sensor may also be an ultrasonic proximity sensor, a capacitive proximity sensor, a microwave radar sensor, or any other non-contact sensor capable of detecting the presence of an object within a preset distance. Any sensor capable of achieving the function of "detecting the presence of an object within the effective detection range" can be used as the proximity sensor of this invention.

[0031] Both types of sensors adopt a privacy-friendly structural design: the photosensitive window has a structure that combines an array of slits and a dot matrix, the surface of the photosensitive window is covered with a gradient dark filter, and the outer surface of the sensor has concave and convex functional markings. This structure only collects physical parameters related to light and distance and does not have image acquisition capabilities, thus avoiding the risk of privacy leakage from the source of data collection.

[0032] Optionally, this embodiment may also include a wireless communication unit, such as a Bluetooth module, for receiving the screen on / off signal or connection status signal of the mobile terminal and participating in the trigger judgment as an auxiliary criterion. When the wireless communication unit is not connected, the system still operates independently.

[0033] Step S2, Environmental Status Judgment: Compare the brightness value collected by the ambient light sensor with the preset dark environment threshold. When the brightness value is lower than the preset dark environment threshold, enter the dark standby state.

[0034] In this embodiment, the preset dark environment threshold is set to 5 Lux. If the sampled values ​​are all below 5 Lux for several consecutive times, it is considered to have entered a dark standby state; otherwise, monitoring continues.

[0035] Step S3, Trigger Judgment: In dark standby mode, if the first and second conditions are met simultaneously, it is determined that the user is using the mobile phone.

[0036] The first condition is: the ambient light sensor detects a significant increase in brightness value exceeding a preset incremental threshold within a short period of time, and this increase remains stable for a first preset duration.

[0037] The second condition is that the proximity sensor detects the presence of an object within its effective detection range.

[0038] In this embodiment, the preset incremental threshold is set to 2 Lux, and the first preset duration is set to 5 seconds. The first condition is specifically: the ambient light sensor detects a brightness value that rises by more than 2 Lux within a short period, and this higher brightness value remains stable for 5 seconds; this condition simulates the user turning on the phone screen. The second condition is specifically: the proximity sensor detects an object within its effective detection range, and the distance between the object and the sensor is less than a certain range, remaining stable for a certain duration; this condition simulates the user holding the phone close to the bedside lamp area. When both conditions are met simultaneously, it is determined that the user is using the phone.

[0039] Step S4, Lighting Control: When the judgment condition of step S3 is met, the lighting module is controlled to turn on to the first brightness level in a smooth and gradual manner; when the first or second condition is no longer met and continues for a second preset time, the lighting module is controlled to turn off in a smooth and gradual manner.

[0040] In this embodiment, after the determination condition is met, the control module sends a command to the lighting module to turn on the lighting to the first brightness level in a smooth and gradual manner. The first brightness level has an illuminance of 12 Lux and a color temperature of 2700K at 0.5 meters, which is output by the lighting module. When either the first or second condition is no longer met, such as when the user turns off the phone screen or puts the phone down, and this continues for a second preset time (in this embodiment, this time is set to 2 minutes), the lighting module is then turned off in the same smooth and gradual manner, and the system returns to a dark standby state.

[0041] Step S5, Manual Mode Switching: In any state, upon receiving a user's contactless trigger operation, the system enters manual mode. In manual mode, each contactless trigger operation causes the light to cycle sequentially between the first brightness level, the second brightness level, and the off state. After switching to the off state, the system automatically returns to step S1.

[0042] In this embodiment, the non-contact triggering operation is a non-contact sensing operation, such as capacitive sensing. In any state, when the user hovers their hand above the sensing area for 1 second, the non-contact interaction unit generates a trigger signal, and the system enters manual mode. In manual mode, each identical non-contact triggering operation causes the light to cycle through a first brightness level, a second brightness level, and then the light to be off. The second brightness level provides an illuminance of 50 Lux at 0.5 meters. When the user switches from the second brightness level to the light-off state, the system automatically returns to step S1, resuming environmental monitoring and automatic triggering logic, achieving a seamless transition between automatic and manual modes.

[0043] like Figure 2As shown, an intelligent bedside lamp control system includes: an ambient light sensor for collecting ambient light brightness values; a proximity sensor for collecting user proximity signals; a non-contact interaction unit for receiving non-contact trigger operations from the user; a control module connected to the ambient light sensor, proximity sensor, non-contact interaction unit, and lighting module, configured to execute the above control methods; and a lighting module for outputting light according to the instructions of the control module.

[0044] In this embodiment, the lighting module consists of a 2700K warm yellow LED light source array, a constant current drive circuit, and a freeform surface microstructure lens, employing an asymmetric light distribution method to output light. The asymmetric light distribution lens creates a high-brightness core area in the user-preset supplementary lighting area, with the light gradually attenuating from the core area to the surrounding area, confining the light to the user side and effectively avoiding interference with other people resting in the same space. The non-contact interaction unit is an array of sensing electrodes, evenly distributed on the bedside lamp operating surface. The electrode surface is covered with an anti-interference shielding layer, enabling stable non-contact interaction. In this embodiment, the array of sensing electrodes is a capacitive sensing electrode. In other embodiments, the sensing electrodes can also be infrared sensing electrodes, ultrasonic sensing electrodes, or microwave radar sensing electrodes, as long as non-contact triggering operation can be achieved. The control module uses an ESP32-C3 main control chip to complete sensor data acquisition, threshold comparison, timing logic, and generation of lighting control commands. All logic is implemented by the ESP32-C3 main control chip, using pure rule-based logic control, requiring no complex models or cloud computing, and can operate stably on a low-cost microcontroller with extremely low power consumption.

[0045] The ambient light sensor and infrared proximity sensor have a photosensitive window with an array of slits and a dot matrix structure. The surface of the photosensitive window is covered with a gradient dark filter. The outer surface of the sensor has raised and recessed function markings to clearly indicate that it does not have image acquisition capabilities, thus eliminating user privacy concerns.

[0046] Therefore, when users use their mobile devices at night, the lights can reliably and automatically trigger and turn off according to the above-mentioned rules and logic, without frequent false triggering. The asymmetric light distribution design effectively limits the illumination range and will not disturb people resting in the same space. The entire control process requires no complex model, can run stably on a low-cost microcontroller, and has extremely low power consumption.

[0047] It should be noted that the combination of the technical features in this case is not limited to the combination methods described in the claims of this case or the combination methods described in the specific embodiments. All technical features described in this case can be freely combined or combined in any way, unless they contradict each other.

[0048] It should also be noted that the embodiments listed above are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and similar changes or modifications made thereto are those that can be directly derived or easily conceived by those skilled in the art from the content disclosed in the present invention, and should all fall within the protection scope of the present invention.
