To change the illumination intensity of indoor LED lamps, the WIFI module 11 is connected with a mobile terminal. The OLED display screen 14 is connected with a clock module 20, the clock module 20 is connected with the STM32F103 single-chip microcomputer 2, and the STM32F103 single-chip microcomputer 2 controls the timing on or off of indoor lighting etc. through the clock module 20. The light detection circuit 9 is connected with the sound detection circuit 10 so that the LED lamp can realize the sound control function. The intelligent controller 1 is also provided with a voice player 21 connected to the clock module 20 . A room button switch 22 is arranged in the intelligent controller 1, and each room in the room can be numbered, so that the intelligent controller can individually control the lights in each room through the room button switch.

First number the room where the LED lights are located, and then divide the room into two types of rooms: bedroom and non-bedroom:

There are normal working mode, smart working mode and timing working mode in the bedroom. The normal working mode is the default working mode of the system, and the system can be switched on and off by pressing the buttons, and at the same time, the timing on and off of the lights can be set through the mobile terminal; the smart working mode The mode system detects the light intensity of the room through the light sensor, and detects whether there are people within the set range through the human body pyro-infrared sensor. If there are people, it compares the light intensity with the set threshold. The threshold is set to High, Middle and Low. If the light intensity is greater than High, the light will be turned off. If the brightness is between High and Middle, the light brightness will be weak. If the brightness is between Middle and Low, the brightness will be medium. If the brightness is lower than Low, the light will be turned off. The brightness is high. If the temperature is higher than the set threshold temperature, the white LED light control circuit will be used to turn on the cool light. If the temperature is lower than the threshold, the warm color LED light control circuit will be set to turn on the warm light. The light can be turned off through the mobile terminal. Operation, restore normal working mode after turning off the light; timing working mode sets the light on and off through the clock module, this working mode is generally used for turning on when the user sleeps at night, and the setting is completed by moving, and the light changes from strong to weak when the timing is off Turn off slowly, the default turn-off time is ten minutes after the mode is switched, and the wake-up ringtone is played through the voice player when the light is turned on at regular intervals, the default turn-on time is 7:00 in the morning, the turn-on and turn-off time can be set through the mobile terminal, in this working mode The voice control function can be turned on through the button, and the sound is detected by the sound sensor. When the volume is greater than the set threshold, the light is turned on to quickly turn on the light in sleep mode; the light intensity in the bedroom is weak, and it is relatively soft, which is good for users to rest.

Non-bedroom rooms have normal working mode, intelligent working mode and movie watching working mode. The normal working mode is the default working mode of the system, and the system can be switched on and off through the buttons, and the lights can be turned on and off at regular intervals through the mobile terminal. At the same time, in the normal working mode, the voice control mode can be turned on and off by pressing the button; in the intelligent working mode, the system detects the light intensity of the room through the light sensor, and detects whether there is anyone within the set range through the human body pyro-infrared circuit. When the movie viewing mode is turned on, The light intensity is kept stable at a weak level to create a theater atmosphere and improve the user's perception of watching movies at home.

Different room types have different working modes, all of which can be set through the mobile terminal to complete the main functions of timing switch, switching the working mode and adjusting the temperature threshold; the invention can realize that when the light intensity is lower than the threshold, it is detected that there are people in the room to automatically open Lighting, and automatically adjust the light intensity according to the different light intensity in the room, set the heating and cooling of the light according to the indoor temperature, and set the timing mode and movie viewing mode according to different rooms, making the system more humanized; realize timing and slow turning off the lights, Turn on the light and voice control function.
