Abstract

The invention is suitable for the field of lamps and provides a battery booster circuit, a lamp control circuit and an emergency lamp. The battery booster circuit comprises a PWM control unit and a booster unit. In case of power cut, the booster unit of the battery booster circuit boosts a battery voltage according to a PWM control signal output by the PWM control unit and the battery voltage is supplied to the emergency lamp, so that the emergency lamp can run normally. Therefore, the requirements of construction, emergency service, disaster relief places and the like on the emergency lamp are met, and convenience and safety are brought to life of people.

Description

technical field [0001] The invention belongs to the field of lamps, and in particular relates to a battery voltage boosting circuit, a lamp control circuit and an emergency lamp. Background technique [0002] At present, many emergency lights are widely used in various factories, venues and some other outdoor construction, emergency rescue and disaster relief places. [0003] Due to the failure of various lines and equipment, power outages often occur in these places. Some remote areas do not have mains power at all, and emergency lights cannot work normally. If there is no reliable and effective emergency lighting equipment, some ongoing work, Operation activities will not be carried out normally, which will bring great inconvenience to people's lives, and in serious cases will bring huge losses to people's lives and property. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a battery voltage boosting circuit, aimin...
