Multifunctional LED emergency lamp and using method thereof

Abstract

The invention discloses a multifunctional LED emergency lamp and a using method thereof. The multifunctional LED emergency lamp comprises a first mains supply input, a second mains supply input, a first rectifier module, a second rectifier module, a relay KA1, a relay KA2, a relay KA3, a switch S1, a switch S2, an LED lamp and a battery. When a first mains supply supplies power normally, the coilof the relay KA1 is powered on, a normally closed contact KA1.1 and a normally closed contact KA1.3 of the relay KA1 are disconnected, a normally open contact KA1.2 and a normally open contact KA1.4 of the relay KA1 are closed, and the on-off of the LED lamp is controlled by the switch S2. When the LED emergency lamp is used under emergency, the switch S1 is closed in advance. Under the normal power supply state of the first mains supply, the loop of the switch S1, a battery management module, the battery, KA1.4 and KA1.2 is switched on, and the battery is charged. After the mains supply is cut off, the coil of the relay KA1 is powered off, the loop of the battery, KA1.3, the LED lamp and KA1.1 is switched on, the battery supplies power to the LED lamp, and the LED lamp is turned on to provide emergency lighting for people.

Description

technical field [0001] The invention belongs to the technical field of emergency lights, and in particular relates to a multifunctional LED emergency light and a using method thereof. Background technique [0002] Emergency lighting is an important part of architectural lighting, especially the basic conditions for protecting personal safety during accidents. Due to the development and advantages of the current LED light source, it has gradually replaced the traditional light source in general lighting. Because of its advantages, it is widely used in emergency lighting. [0003] The emergency light generally has its own battery, and its working method is: usually charge the battery of the emergency light, and when the normal power supply is cut off, the emergency light is automatically powered by the backup battery. [0004] Emergency lights are divided into constant-on type and normally-off type according to the usual lighting state. The constant-on type is usually on, and...

AI Technical Summary

Problems solved by technology

[0005] The existing LED emergency lights have a single function and low economic performance. Through the analysis and research of its specifications, designs, methods, technical data, and system products, the present invention finds out the omissions and deficiencies in the emergency lighting settings, and the possible solutions to them. Certain feasible measures and methods that are highly efficient, can be optimized, and can be improved
