Self-locking circuit for mobile lighting equipment and mobile lighting equipment

Abstract

The invention provides a self-locking circuit for mobile lighting equipment. The self-locking circuit comprises a switching circuit and a driving circuit, the driving circuit is connected with a micro-control unit, the micro-control unit is connected with the switching circuit, the micro-control unit is connected with a magnetic induction self-locking circuit, and the micro-control unit is used for detecting a self-locking signal sent by the magnetic induction self-locking circuit and locking the switching circuit. The magnetic induction self-locking circuit sends out a self-locking signal according to the magnetic field characteristic of the external environment; when the lighting device is placed in a specific locking environment, the magnetic induction self-locking circuit senses the specific magnetic field change of the external environment and transmits self-locking information to the micro-control unit; the micro-control unit locks the switch circuit; the locked switching circuitcannot trigger the driving circuit to enable the mobile lighting device to emit light, locking of the mobile lighting device is achieved, the self-locking circuit enables the device to be locked onlyby being placed in a specific environment, and a user does not need to learn complex and tedious unlocking / locking steps.

Description

technical field [0001] The invention belongs to the technical field of mobile lighting equipment, and relates to a self-locking circuit for mobile lighting equipment and the mobile lighting equipment. Background technique [0002] Mobile lighting devices (such as flashlights) are widely used in daily life and processing and production because of their portability and easy operation. However, due to the portability of general mobile lighting equipment, users will put the equipment in their pockets or store it in other spaces with sundries. If the equipment is lit, if the user does not find out in time, it will seriously consume the power of the equipment, especially for mobile lighting equipment with high power, if it is turned on for a long time, it may cause a fire due to excessive temperature. [0003] In order to solve the problem of false touches of mobile lighting equipment, the current common method is to lock the keys through software, such as figure 1 As shown, the...

AI Technical Summary

Problems solved by technology

However, this key locking method makes the circuit design of the key locking / unlocking complex, and the unlocking steps are cumbersome. When using the product, the user must read the manual in detail and learn the key locking / unlocking method, and at the same time remember its usage method

Unlock by long pressing the button, even when the mobile lighting device is squeezed by a hard object for a long time, it can also be unlocked, which is prone to accidental unlocking

[0004] Therefore, the current mobile lighting equipment has the problems of complex and cumbersome locking and unlocking methods, and a high rate of false unlocking.
