A device and a lamp capable of turning off emergency functions

Abstract

The invention belongs to the field of electronic technology, and discloses a device and a lamp capable of turning off emergency functions. A stabilized power supply is generated by a first voltage stabilizing module according to a power supply; a button module generates a button signal according to user input; Key signal, output current sampling signal and output voltage sampling signal generate control signal and original pulse width modulation signal; switch module generates switching signal according to power supply and control signal; power conversion module generates according to power supply, switching signal and original pulse width modulation signal Output power supply; the output current sampling module performs current sampling on the output power supply to generate an output current sampling signal; the output voltage sampling module performs voltage sampling on the output power supply to generate an output voltage sampling signal; therefore, the output power supply can be generated or stopped by a button signal, thereby The emergency function is turned off, which improves the flexibility of the device with the emergency function and prevents the waste of electric energy.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a device and a lamp capable of shutting down an emergency function. Background technique [0002] The traditional emergency function device includes a mains detection module, a control module, a switch module and a power conversion module. The mains detection module generates a mains detection signal according to the mains. The control module generates a control signal according to the mains detection signal. The signal connects to battery power to power the LEDs. Since the emergency function must be activated when the mains power is disconnected, the traditional emergency function devices have poor flexibility and lead to waste of electric energy when the emergency function is not needed. [0003] Therefore, the traditional emergency function device has the defects that the emergency function cannot be turned off, resulting in poor flexibility and waste of elect...
