Emergency Lights Illumination Is Provided When A Fault Occurs

Domestic Emergency Lights in recent years have a greater development in the technical indicators have a corresponding improvement. The development of Emergency Lights business also highlights the importance of human safety of their lives, the corresponding Emergency Lights work has also been a wide range of concerns. So what is the working principle of Emergency Lights?

Emergency Lights features

Emergency Lights with reliable work, high stability, low power consumption, high brightness, long life and other characteristics, the edge design of the power switch and refers to the lights, is widely installed in public places corridors, fire channel.

Emergency working principle

First we analyze from the structure. Emergency light inside the two sets of power supply system, a set of internal battery to the power supply, a set of external power supply to the lights while the battery charge, the other power conversion mechanism, when the external power supply disconnected (power outage) , The line will switch to the battery power supply. This can be in the emergency lights when the power is turned off the emergency lights will remain illuminated.

Understand the Emergency Lights power supply principle, in a brief understanding of the next working principle. Domestic use of Emergency Lights system to own power independent control type, the normal power supply from the ordinary lighting power supply circuit, usually on the emergency light battery charging, when the normal power cut off, the backup power supply (battery) automatic power supply. This form of emergency lights each lamp has a transformer, voltage regulator, charge, inverter, battery and other large number of electronic components, emergency lights in the use, maintenance, failure, the battery charge and discharge. The other is centralized power centralized control type, emergency lights without independent power supply, the normal lighting power failure, by the centralized power supply system. In this form of Emergency Lights system, all the internal electronic circuit is saved, the Emergency Lights and ordinary lighting is no different, centralized power supply system set in a dedicated room.

Emergency lights can be sorted by operating status and function. According to the working state can be divided into three categories: ① continuous emergency lights. Regardless of whether the normal lighting power supply failure, can continue to provide lighting. ② non-persistent emergency lights. Lighting is provided only when a normal lighting power supply fails. ③ composite emergency lights. Lamp Emergency Lights with more than two light sources, at least one can be in the normal lighting power supply failure to provide lighting.

According to the function can be divided into two categories: ① lighting type lighting. In the event of an accident, the necessary lighting can be provided to the aisle, exit channel, stairway and potential danger zone. ② logo lamps. Can clearly indicate the direction of exports and channels, the lights have text and icons, marking the brightness of 7 ~ 10cd / m2, the text of the brush at least 19mm, height of at least 150mm, observation distance of 30m, translucent text and background Big contrast.
