the human body sensing module is used for sensing the relative position of a person and the main body when the standby power supply supplies power, the main control module judges the current state of the person according to the relative position, and the illumination state and illumination brightness of the LED module are adjusted according to the current state of the person.
Specifically, there may be two cases when the power grid is powered off: one is that a person suddenly cuts off the power when using a toilet or washing or bathing in a bathroom, and the other is that the person needs to enter the bathroom to use the toilet or washing or bathing when cutting off the power.
In the former case, the invention senses whether the mains supply is supplied or not at all times through the power-off sensing module, and residual electric quantity is necessarily generated when the power is off, and the main control module can be switched to the standby battery to supply power in time at the moment, so that all power-on modules/modules can continue to work; the power-off time is uncertain, so that the lighting is required to be ensured to save electricity after power-off, and the position and the gesture of a human body are identified through the human body sensing module, so that the current state (namely the ongoing matters) of the human body is judged, and the current state is used as the adjustment basis of the working state of the LED module.
In the latter case, after a person enters the space where the invention is located and wakes up the main control module, the main control module is powered by the standby battery when being waken up in the power-on or power-off state, so that the main control module firstly acquires the information of power failure of the mains supply after being waken up, then maintains the state of being powered by the standby battery, and enables the LED module to adjust the lighting state according to the current state of the person.
In this embodiment, the LED module includes a plurality of LED light bars disposed on the main body, an LED driving module is disposed between the LED light bars and the main control module, and the main control module is connected with a brightness sensing module; the main control module judges the current state of the person according to the relative position, and adjusts the illumination state and illumination brightness of the LED module according to the current state of the person, and specifically comprises the following steps:
the main control module judges the current state of the person according to the position and the gesture of the person sensed by the human body sensing module;
ambient brightness L in control of intelligent lamp mirror is sensed through brightness sensing module 0 ；
When the state of the person is judged to be the toilet state, the main control module controls the LED lamp strip close to one side of the person to have brightness k (L 1 -L 0 ) The LED lamp strip is illuminated, and other LED lamp strips are extinguished;
when the state of the person is judged to be a bathing state, the main control module controls the LED lamp strip close to one side of the person to have brightness k (L 2 -L 0 ) The LED lamp strip is illuminated, and other LED lamp strips are extinguished;

wherein L is 2 ＞L 1 ＞L 3 ，L 2 、L 1 And L 3 All are preset brightness values, and k is a positive number.
Specifically, according to the layout of a common bathroom, the washing table is closest to the lamp mirror, the toilet is the next more, and the shower head is the farthest. While the need for illumination is highest. Therefore, the invention judges the current state of the person according to the position and the posture of the person, and controls the LED module to illuminate according to the state. Meanwhile, when the user uses the lamp to go to a toilet or bathe, the lamp is usually positioned at one side of the lamp mirror, so that the LED module at the close side only needs to illuminate in the state, and other LED modules enter a dormant state to save electric energy; in washing, the washing table is arranged under the lamp mirror, so that all the LED modules are simultaneously used for low-brightness L after washing 3 And (5) illuminating.
The invention combines the current ambient brightness L in the bathroom because the ambient brightness in the bathroom is different when the power is off 0 The final illumination brightness of the LED module is controlled, and the coefficient k is a positive number, namely, after the current environment brightness and the preset brightness are combined, the coefficient k is multiplied to obtain the brightness compensation of the LED module.
Specifically, if L 1 Less than L 0 When the state of the person is judged to be the toilet state or the washing state, the LED lamp strip does not illuminate;
if L 2 Less than L 0 When the state of the person is judged to be a bathing state, a washing state or a toilet state, the LED lamp strips are not illuminated;
if L 3 Less than L 0 When the state of the person is judged to be the washing state, the LED lamp strip does not illuminate.
The ambient brightness is larger than the preset brightness value, and the condition that compensation illumination is not needed under any one or more conditions is judged according to the fact that the ambient brightness is larger than the preset brightness value, so that the electric energy saving is further ensured.
Specifically, the preset brightness value can be set in combination with local real-time and time period, so as to ensure that the illumination brightness cannot be uncomfortable to people.
Specifically, the main control module still is connected with identification module, and identification module is used for the whether sense has someone to get into intelligent lamp mirror place space, and main control module judges the current state of people according to relative position still includes:
