Specifically, as shown in FIG. 2 , power is supplied to the light control circuit through a power adapter. The control module 20 implements the following functions:

ADC temperature acquisition: The internal ADC temperature sensor of the third main control chip (U3) collects the voltage value of the adjustable resistor (R17) through the adjustable resistor (R17) to obtain the temperature information, preferably, every 10 seconds through the serial port The temperature information is sent to the wireless communication module 10, and the wireless communication module 10 sends the temperature information to the mobile terminal 1, so that the mobile terminal 1 periodically displays the temperature information.

Power output control: the human-computer interaction module 30 obtains the operation information input by the user and parses the operation information to obtain the corresponding control signal; in addition, the wireless communication module 10 receives the operation information of the mobile terminal 1 and parses the operation information to obtain the corresponding control Signal. During operation, the control signal from the human-computer interaction module 30 and/or the wireless communication module 10 is received, and the voltage duty cycle of the output power supply is adjusted according to the control signal, so as to realize the switch of lamps 3 and lamps at any time according to the change of the voltage duty cycle 3 Brightness value adjustment.

Exemplarily, when the light fixture 3 is switched to the off state, the duty cycle is not abruptly changed, but is gradually changed at a preset period (for example, 20ms), so as to realize the smooth change of the light without flickering and extinguishing. For example, the duty cycle corresponding to the brightness value of lamp 3 is 70% in the lighting state, then control lamp 3 to reduce the duty cycle value according to the duty cycle difference of 10% every 20ms, that is, from the first 20ms after the lamp 3 is reduced from 70% to 60%, and after the second 20ms, light fixture 3 is reduced from 60% to 50%, and so on until the duty cycle reaches 0 and light fixture 3 is switched off. Similarly, when the lamp 3 is switched to the lighting state, the duty cycle is not abruptly changed, but is gradually changed at a preset period (for example, 20ms), so as to realize the smooth change and flicker-free lighting of the light. For example, the duty cycle corresponding to the off state of the lamp 3 is 0, and assuming that the duty cycle corresponding to the lighting state of the preset lamp 3 is 5%, the lamp 3 is controlled to increase every 20ms according to the difference of the duty cycle by 1%. The duty cycle value, that is, the lamp 3 is increased from 0 to 1% after the first 20ms, and then the lamp 3 is increased from 1% to 2% after the second 20ms, and so on until the duty cycle reaches 5%.

Light brightness state memory function: the light brightness value is 0x00-0x64, that is, the brightness of light fixture 3 can be set to 0%-%. The third processing unit compares the light brightness value every 2 seconds, and when the change difference exceeds 5, the third processing unit writes the light brightness value into the specified position of the internal FLASH. When the system is powered on and running again, the third processing unit lights up by reading the value stored in the position as the light brightness value.

PWM breathing effect: The effect of breathing light is realized through PWM control, and 90 points are sampled in a breathing curve cycle and stored in the pwm list, so that the brightness of lamp 3 can gradually change from light to dark.

In the above embodiment, the wireless communication module 10 , the human-computer interaction module 30 and the control module 20 respectively perform cascade communication through the first communication connector unit, the second communication connection unit and the third communication connection unit.

DISABLE: Turn off the breathing effect scene

LONGTIME: Set the current progress bar value and enable the breathing scene effect

3. TIM SYNC: Synchronize the system clock immediately

4. AUTO: Turn on/off unattended mode

Lighting control: The mobile terminal 1 can control the opening and closing of the front light, the intensity control of the brightness of the light, and the opening and closing of the light breathing effect (the breathing duration can be adjusted). Exemplarily, the user can set the light brightness to 31% or 81% as required.

Unattended mode: the lights are automatically turned on during the preset working time period from 9:00 to 18:00, and will be automatically turned off beyond the preset working time period. Mechanical buttons or touch buttons at the mobile terminal 1 and the human-computer interaction module 30 This mode can be turned on or off.

Clock calibration: When the mobile terminal 1 is connected to the lighting control system corresponding to the smart front desk, the time of the mobile terminal 1 can be manually synchronized to the lighting control system of the smart front desk, accurate to the second.

Temperature monitoring: The lighting control system of the intelligent front desk sends the real-time temperature information collected by the control module 20 to the mobile terminal 1 to monitor whether the temperature is normal.

This solution realizes that the mobile terminal 1 completes the functions of lighting control, breathing special effects, unattended mode, clock calibration, and temperature monitoring through wireless communication. Exemplarily, schematic diagrams of the effect of the present invention for adjusting the brightness of a lamp are shown in FIG. 14 and FIG. 15 , and FIG. 14 corresponds to setting the brightness of the lamp at 31%.
