Working method for emergency lamp

Abstract

The invention discloses a working method for an emergency lamp, and the method comprises the following steps: (1) controlling an illumination lamp to work through sound and light when an AC source provided by the commercial power is normal, and enabling a lamp bulb to be off when the light intensity is high; (2) obtaining sound through a sound pickup and turning on the lamp bulb when there is huge sound; (3) enabling the level of a sixth pin of a time-base integrated circuit to rise continuously; (4) turning off the lamp bulb when the level of the sixth pin of the time-base integrated circuit reaches a set voltage, and resetting a whole sound and light control illumination circuit; (5) enabling a charging circuit to charge a storage battery through a constant current charging circuit when the sound and light control illumination circuit is in operation, and enabling a trickle charging circuit to carry out charging when the voltage of the storage battery reaches a preset value; (6) enabling a standby lamp bulb to be turned on when the AC source provided by the commercial power stops working; (7) enabling the standby lamp bulb to be turned off when the AC source provided by the commercial power recovers to work. The method enables the number of corridor lamps and emergency lamps, enables the installation to be simple, and enables the maintenance to be convenient.

Description

technical field [0001] The invention relates to the field of lamps, and specifically discloses a working method of an emergency lamp. Background technique [0002] When a major accident occurs, escaping from the stairwell is often the safest escape path for people. However, because there is often a power outage when a major accident occurs, and the stairwells are generally dark, it is not conducive to people's rapid evacuation. The emergency lights installed in stairwells are generally dim, and the range of exposure is very blurred. For people with poor eyesight, they cannot see the stairs clearly, which may easily cause falls. Moreover, the current emergency lights and corridor lights are basically set separately, which increases the amount of wiring and installation on the first floor, and is not conducive to line maintenance. Contents of the invention [0003] The present invention intends to provide a working method of emergency lights to solve the problems that exis...
