Problems solved by technology
Due to the excessive use of the lamps, that is, the excessive consumption of batteries, this will lead to over-discharge of the batteries, resulting in shortened battery life, shortening the service life of the lamps, and increasing the use and replacement costs of the lamps.
Especially in occasions where this type of lamp is required, if the lamp cannot be used normally at an important moment due to over-discharge of the battery, it may cause unpredictable losses
In addition, other scenes that need to use battery power also have similar battery over-discharge problems

The embodiment of the present invention discloses an alarm circuit, including: a comparison module, connected to the positive pole of the battery, used to compare the input reference voltage and the voltage of the battery, and output a corresponding level signal; The module is connected to receive the level signal, and the power-on alarm reminds the user; the switch module is connected to the comparison module, used to receive the level signal, and controls the circuit of the battery to open to protect the battery. By adopting the invention, an alarm can be given to remind the user when the battery is over-discharged, and the battery circuit can be opened to avoid over-discharge of the battery, thereby improving the stability of the lamp in use and prolonging the service life of the battery and the lamp.
Description
technical field [0001] The invention relates to the field of electronics, in particular to an alarm circuit. Background technique [0002] The stability and life of lamps are very important, and have a very important impact on people's daily life and work. For lamps powered by batteries, the battery life is an important indicator to measure the overall stability and life of the lamp. Due to the excessive use of the lamps, that is, the excessive consumption of batteries, this will lead to over-discharge of the batteries, resulting in shortened battery life, shortening the service life of the lamps, and increasing the use and replacement costs of the lamps. Especially in occasions where this kind of lamp is required, if the lamp cannot be used normally at an important moment due to over-discharge of the battery, it may cause unpredictable losses. In addition, other scenarios that require battery power also have similar battery over-discharge problems. Contents of the inven...
