Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to a segmented power supply type multi-channel touch bluetooth control single live wire switch circuit. Background technique [0002] Existing LED lamps have a single power supply mode, and generally only one power supply module provides power to them, so that flickering occurs when the power is off, and the relay in the power-on state is prone to jumping, resulting in the instability of the entire circuit. [0003] The reasons are: (1) When the circuit is in standby, due to the large power consumption of the Bluetooth module circuit, if a conventional power supply circuit is used, the current of the entire loop will inevitably increase. Low-power LED lights are more sensitive to the leakage of the loop and have lower efficiency. The sensitivity of LED lights powered by isolated power supply will be lower, but the sensitivity of high-efficiency non-isolated p...

Problems solved by technology

[0002] Existing LED lights have a single power supply mode, and generally only one power supply module provides power to them, which will flicker when the power is turned off, and the relay in the power-on state is prone to beating, resulting in the instability of the entire circuit

[0003] The reasons are: (1) When the circuit is in standby, due to the large power consumption of the Bluetooth module circuit, if a conventional power supply circuit is used, the current of the entire loop will inevitably increase. Low-power LED lights are more sensitive to the leakage of the loop and have lower efficiency. The sensitivity of LED lights powered by isolated power supply will be lower, but the sensitivity of high-efficiency non-isolated power supply is higher. The leakage current in the circuit loop cannot be consumed by the power supply circuit. When the stored voltage reaches the start-up voltage of the power supply VDD , the power supply circuit will start, and the stored voltage will be discharged at the moment of start-up, and the LED light will flash once;

[0004] (2) When the circuit is working, also due to the large power consumption of the Bluetooth module circuit, if a conventional power supply circuit is used, the current of the entire circuit will inevitably increase. If the load is a low-power LED light, the power supply current of the relay will be insufficient, which will cause Quick snap-release of this beating state
