Abstract

The invention discloses a small-size household emergency lamp which comprises a 6V direct-current power source, a feedback type oscillation circuit and a boosting and lighting circuit. The small-size household emergency lamp is a standby lighting facility independent from the mains power grid, can fit with a daylight lamp of 3-4W, can meet the requirement for emergency lighting during temporary power interruption of a power supply circuit, is also applicable to emergency lighting or firefighting lighting in various small public places. Besides, if with four 1# Mn-Zn dry batteries, the small-size household emergency lamp can light in more than 2 hours. The small-size household emergency lamp has the advantages of simple circuit structure, reliable work and low manufacturing cost and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic technology and emergency lighting, and relates to a small household emergency light. Background technique [0002] Now people are more and more dependent on power supply. Even if a temporary power outage occurs, it will have a certain impact on normal work, life and study or cause some economic losses. The small household emergency light of the present invention is a kind of standby lighting equipment independent of the mains power grid. It can be equipped with 3-4W fluorescent lamps. It can meet the emergency lighting needs during the temporary power failure of the power supply line. It is also suitable for Emergency lighting or fire fighting in various small public places should be specified. If 4 pieces of 1# manganese zinc dry batteries are used, the lighting time of the small household emergency lights is more than 2 hours. The invention has the characteristics of simple circuit structure...
