And transmits the voltage value, the current value, or the output off control signal to the PWM pulse control module 10222.
Referring to fig. 3 and 7, the ethernet module 10221 includes: the ethernet integrated circuit is connected to the PWM pulse control module 10222, and configured to unpack ethernet data and transmit the unpacked data to the PWM pulse control module 10222.
The Ethernet interface module is respectively connected with the Ethernet integrated circuit and the router and used for converting Ethernet level. Therefore, the control signal is in data communication with other Ethernet equipment, and the control signal output by other Ethernet equipment is received. It should be noted that the control signal may be an output voltage value, a current value, or an output shutdown control signal. And transmits the voltage value, the current value, or the output off control signal to the PWM pulse control module 10222.
The PWM pulse control module 10222 is connected to the ethernet module 10221, and configured to receive the control signal transmitted by the ethernet module 10221, and output the PWM pulse signal according to the control signal. For example, when the control signal is a 5A, 25V current-voltage control signal, the PWM pulse control signal corresponding to the 5A, 25V current-voltage control signal is output, and by sampling the output current and voltage. So that the AC-DC conversion circuit 1021 outputs a stable current voltage of 5A, 25V.

Specifically, the resistor R2, the thermistor TH1, and the resistor R3 constitute a voltage dividing circuit. When the temperature on the LED lamp increases, the resistance value of the thermistor TH1 decreases with the increase of the voltage. So that the current on the loop consisting of the resistor R2, the thermistor TH1 and the resistor R3 is increased. The voltage division values of the resistor R2 and the resistor R3 are respectively increased. The voltage value of the feedback voltage Uf connected in series by the thermistor TH1 and the resistor R3 is reduced due to the increase of the voltage division value of the resistor R2. The feedback voltage Uf is fed back to the acquisition terminal Uf of the controller module 10. After the controller module performs AD analog-to-digital conversion on the feedback voltage Uf, the temperature information of the LED lamp can be acquired from the feedback voltage Uf. For example, when the voltage value of the feedback voltage Uf decreases, it indicates that the temperature of the LED lamp increases.
In addition, the one end of the resistor R3 is connected to a voltage comparison end of the shunt U2, and when the current in the resistor R3 increases due to the decrease in the resistance value caused by overheating of the thermistor TH1, the voltage in the resistor R3 increases, so that the voltage comparison end voltage of the shunt U2 increases, and the currents in the positive and negative ends of the shunt U2 increase, so that the shunt in the resistor R2 further increases. The feedback voltage Uf is further reduced, so that the temperature information of the LED lamp is quickly reflected. In use, the controller may be arranged to control the power supply drive circuit to reduce the output power when the feedback voltage Uf falls to a value.

When the intelligent control module 1022 is in use, the intelligent control module 1022 outputs a high-low level signal through the first control end, when the intelligent control module 1022 outputs a high level, the triode Q3 is turned on, and meanwhile, the relay U9 is closed, and the mains supply is output by the relay. When the intelligent control module 1022 detects that the temperature is too high through the temperature sensor, or an external control signal needs to turn off the mains supply alternating current, the intelligent control module 1022 may output a low-voltage signal, the low-voltage signal enables the triode Q3 to be cut off, and the relay U9 is turned off, so that no power is output from the output end of the relay.
