The invention will be further described with reference to examples and drawings, to which reference is made, but which are not intended to limit the scope of the invention. The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the bathroom mirror LED control system capable of changing the irradiation angle provided by the invention comprises a main control module, a brightness monitoring module, a brightness control module, a driving module and a capturing module which are all electrically connected with the main control module,
the brightness monitoring module is used for monitoring the ambient brightness around the bathroom mirror;

s5, controlling the LED lamps to rotate in the directions opposite to each other through the driving module.
When in actual use, the LED lamps on the bathroom mirror are mostly used for realizing two functions: one is used for illumination, namely when the user goes to a toilet at night, the LED lamp on the bathroom mirror is used for illumination without the ceiling lamp of a bathroom, so that energy is saved, and the too strong light is avoided; another is to have the effect of increasing the brightness, for example, by which a person looks at the face details more clearly.
The invention is based on the two functions, and achieves the following effects: when a person enters a bathroom (namely, a space in which the bathroom mirror is positioned) through the capture module, if the person does not stand in front of the bathroom mirror after entering, the person is judged to enter the bathroom for toilet, and at the moment, the drive module is used for controlling the LED lamp to rotate outwards, so that the irradiation range of the LED lamp is larger, the bathroom mirror is used as an illumination light source, the brightness is not too high, the coverage range is wide, the person can use the bathroom and wash hands in a clear environment, and discomfort is not brought to eyes by suddenly enhanced brightness; when a person stands in front of the bathroom mirror after entering the bathroom, the person needs to look at the mirror at the moment, the driving module controls the LED lamp to rotate inwards, and the mirror can clearly reflect the image of the person by the way that light is concentrated in front of the bathroom mirror.
Whereas in the present invention L 1 ' and L 2 ' is a brightness value set by a person skilled in the art according to the actual needs of the user, belongs to data which can be obtained through limited tests, and is not described herein.
In this embodiment, before step S1, the method further includes:
the main control module acquires local real-time and judges whether other lamps in the space where the bathroom mirror is positioned are started or not;
when other lamps in the space where the local real-time is in the rest time Duan Juwei bath mirror is not turned on, executing the steps S4 and S5; and when the local real-time is not in the rest time period or any other lamp in the space where the bathroom mirror is positioned is started, executing the step S1.
The rest time period can be set according to life work of the person, for example, the person who is used to sleeping at 12 points and getting to work at 7 points can set 0-7 points as the rest time period. When a person goes to a toilet at 3 am, the first sensor is triggered when the person directly walks to the entrance of the toilet, and then the second sensor is triggered after the person leaves the front of the bathroom mirror, so that the condition that the local real-time is in a rest time period and other lamps in the toilet are not turned on is satisfied, and the person afraid of looking into the mirror in the time period can not observe the action of face details for making up and the like, so that the main control module directly executes the steps S4-S5; when a person enters the bathroom under the condition that the light is not turned off in the bathroom in the early morning at 1 point, the main control module needs to execute the step S1 to further judge the requirement of the person entering the bathroom because the condition that the local real-time is in a rest time period and other lights in the bathroom are not turned on is not met, so that the brightness and the rotation angle of the corresponding LED lamps are adapted according to the requirement.
Specifically, the capturing module comprises a first sensor and a second sensor, wherein the first sensor is arranged at a gate of a space where the bathroom mirror is positioned, and the second sensor is arranged at the bathroom mirror;
the step S1 specifically comprises the following steps:
s11, sensing whether a person enters a space where the bathroom mirror is located by the first sensor, if so, executing a step S12, otherwise, not executing an action;
s12, sensing whether a person is positioned in front of the bathroom mirror by a second sensor, if so, executing a step S13, otherwise, executing steps S4-S5;
s13, starting timing by the main control module, and executing the steps S2-S3 when the timing reaches the preset first time but the person is still positioned in front of the bathroom mirror.
Namely, in actual use, the first sensor and the second sensor can be infrared sensors which are used for judging whether a person enters a toilet or not and whether the person looks into a mirror after entering the toilet or not respectively; the first time is mainly used for avoiding that a person passes through the bathroom mirror but mistakenly triggers the bathroom mirror when not in use, and the first time is preferably any value within 3 seconds, so that the LED lamp is not mistakenly triggered due to oversensitivity after the quick response speed of the bathroom mirror is ensured.
Preferably, the capturing module further comprises a catcher, the catcher is arranged on the bathroom mirror, a shielding mechanism for covering the catcher is movably arranged on the bathroom mirror, and the catcher and the shielding mechanism are electrically connected with the main control module;
the capturing module is used for capturing the position and the action gesture information of the person, and further comprises:
the distance between the person and the bathroom mirror is sensed through the second sensor, and when the distance between the person and the bathroom mirror is smaller than a preset distance, the main control module controls the shielding mechanism to act so that the catcher is exposed to the outside;
the catcher is started to catch the relative position between the face of the person and the bathroom mirror and transmit the relative position to the main control module, and the main control module adjusts the brightness and the rotation angle of the LED lamp.
The shielding mechanism can be composed of a linear module and a baffle, the catcher can be a camera, when the second sensor senses that the distance between a person and the mirror surface of the bathroom mirror is smaller than the preset distance, the main control module judges that the person needs to carefully observe the face details, at the moment, the catcher is enabled to be exposed to the outside by controlling the action of the shielding mechanism, the catcher is enabled to shoot images of the person, and accordingly the brightness and the irradiation angle of the LED lamp are controlled according to the position of the face of the person to carry out adaptive adjustment.
When the action of the catcher is not needed, the catcher is in a closed state, and the shielding mechanism covers the front of the catcher, so that the catcher cannot shoot outwards when the catcher does not work, and the privacy of a person is guaranteed.
Preferably, the main control module adjusts and adjusts the brightness and the rotation angle of the LED lamp according to the judgment result, and specifically includes:
the catcher captures the relative position between the face of the person and the bathroom mirror;
the main control module calculates the distance between the relative position and each LED lamp to obtain a plurality of distance values d n ；
According to formula L n ＝k*d n *L 1 Working brightness L of each LED lamp is calculated n ；
Judging each d n The distance d 'from the preset distance d' is d n When the driving module is larger than d', the driving module controls d n The corresponding LED lamps illuminate towards a person; otherwise, the LED lamp illuminates at an angle alpha;
wherein k is a constant greater than 0 and α is 20-45 °.
Because the habits of the mirrors of all people are different, when the trapper is used for matching, the trapper is required to identify the relative positions of the people and the bathroom mirror, so that the main control module can identify the specific positions of the people in front of the mirror surface of the bathroom mirror; after the position of the person is determined, the LED lamp can be controlled to illuminate: if the LED lamp is close to a person, the brightness of the LED lamp is not too high, and the irradiation angle of the LED lamp cannot be over against the person, so that discomfort to the person is avoided; when the distance between the LED lamp and a person is far, the brightness of the LED lamp can be adjusted to be high, and when the distance is larger than the preset distance, the LED lamp directly irradiates the person, so that the effect of supplementing the brightness is achieved.
Preferably, the main control module is connected with a deep learning module, and the main control module analyzes the picture shot by the catcher through the deep learning module.
The main control module can be connected with the Internet regularly to update data, so that the effect of controlling the LED lamp to rotate and changing brightness according to the catcher can be achieved more and more accurately after the deep learning module imports the latest manual training model.
The LED lamp structure of the bathroom mirror is preferably an LED lamp strip arranged around or at two sides of the mirror surface, wherein the LED lamp strip is fixed, but the reflecting cup structure of the LED lamp is rotatable, so that the irradiation angle of the LED lamp is controlled to change by controlling the rotating angle of the reflecting cup.
Therefore, in this embodiment, the driving module includes a plurality of rotating mechanisms, where the plurality of rotating mechanisms are connected to the plurality of LED lamps in a one-to-one correspondence manner;
the rotating mechanism comprises a driving motor 1, a transmission shaft 2 and two limiting blocks 3, wherein the driving motor 1 is used for driving the rotation shaft to rotate, the transmission shaft 2 is connected with a reflecting cup of the LED lamp, the two limiting blocks 3 are respectively used for abutting against the reflecting cup, and the driving motor 1 is electrically connected with the main control module; specifically, the driving motor 1 can rotate with the transmission shaft 2 through the decelerator 8.
When in actual use, the rotating mechanism further comprises a proximity switch 5, the rotating shaft of the driving motor 1 is provided with a trigger piece 6, the periphery of the trigger piece 6 is provided with a plurality of trigger parts 7, the proximity switch 5 is matched with the trigger parts 7 to identify the rotating amplitude of the motor, and the proximity switch 5 is electrically connected with the main control module.
Namely, each LED lamp corresponds to one rotating mechanism, and the rotating range of the reflecting cup of the LED lamp is limited by two limiting blocks 3, so that the influence on the actual action due to overlarge rotating amplitude is avoided; in addition, the invention realizes real-time monitoring of the rotation angle of the driving motor 1 through the cooperation of the trigger piece 6 and the proximity switch 5, namely a plurality of trigger parts 7 are distributed on the trigger piece 6 in an annular array by taking the rotating shaft of the driving motor 1 as the center of a circle, and the distances between the trigger parts 7 and the non-trigger parts 7 and the proximity switch 5 are different, so that the proximity switch 5 can generate different level signals. Based on this principle, when the driving motor 1 drives the rotating shaft to rotate and the trigger piece 6 rotates together, the proximity switch 5 can judge the rotating angle of the driving motor 1 through the change of the level signal, so that the accurate monitoring of the rotating angle of the transmission shaft 2 is improved.
In this embodiment, step S5 specifically includes:
s51, acquiring the moving direction of the person through a second sensor so as to judge the relative position between the person and the bathroom mirror;
s52, the main control module controls the LED lamps positioned on two sides to rotate to the positions facing the people.
The second sensor senses that the person is not standing in front of the bathroom mirror, and can judge the relative position between the person and the bathroom mirror according to the moving direction of the person, and then the LED lamp rotates to the direction facing the person, so that the lighting efficiency is higher.
Of course, the above steps S51 and S52 may be applied in a state when the ceiling lamp of the bathroom is turned on; when a person is in a night state, the LED lamps are still only required to be back-to-back illuminated.
Specifically, the main control module is connected with an alarm module, and in step S51, when a person is captured to move downwards relative to the bathroom mirror, the main control module starts timing;
when the timing reaches the preset second time but the capturing module still does not sense that the person returns to the front of the bathroom mirror again, the brightness control module controls the LED lamp to illuminate with red light, and the timing module continues to time;
when the timing reaches a preset third time but the capturing module still does not sense that the person returns to the front of the bathroom mirror again, the main control module alarms through the alarm module, and meanwhile the brightness control module controls the LED lamp to illuminate with white light with maximum brightness.
That is, when the second sensor senses that a person moves to the position right below the bathroom mirror, the person generally judges that the person looks for an object in a cabinet below the bathroom mirror or falls down due to sudden diseases, so that timing is performed at the moment, when the person is not present in the second sensor for a long time, the person is judged to be abnormal, but in order to avoid misjudgment, the LED lamp is illuminated by red light, the person stands up under the stimulation of the red light to re-sense the second sensor at the moment, and the main control module modifies the situation into normal condition, so that the invention continues to work normally; if the person still does not appear under the sensing of the second sensor for a long time under the abnormal condition, the person can be directly identified as the sudden illness, the main control module can inform the emergency contact person of the person through the alarm module, the emergency contact person can be reminded through any one or more of sending information, making a call and reminding by the APP, and meanwhile, the LED lamp is illuminated with the maximum brightness to try to wake up the person.
Because the bathroom mirror is arranged at the gate of the bathroom, namely, the bathroom mirror is required to pass through no matter what action a person does after entering the bathroom, through the arrangement, when the person is in home alone and encounters an emergency, the person can be found and processed even if the person is found, and the best rescue time is prevented from being missed.
Specifically, the second time and the third time can be set according to actual conditions, for example, the second time is set to 3 minutes, the third time is set to 5 minutes, and under the above time, a person can be ensured to have enough time to search for objects if searching for objects, so that false triggering is avoided to the greatest extent.
The present invention is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present invention.
