An Emergency Lighting Circuit Diagram

Emergency lighting is a type of lights that can effectively illuminate and display exit passageway or can continue to work without interruption when the normal lighting power supply fails,  Widely used in public places where can lighting without intermittent . The emergency lighting fixture is composed of a light source, a light source driver, a rectifier, an inverter, a battery pack, a logo lamp housing something like that.

 

Here is a circuit diagram of an emergency lighting made with LES.

 

The circuit operation of the device is shown in Figure 1. Power outages are a recurring thing, but in some cases power outages are not allowed (such as ongoing surgery). The circuit designed with LSE is simple and fully automated. When there is 220V AC power, the illumination lamp H1 is lit, and the ④ pin of the LSE output with high level output, the Transistor VT is turned off, and the relay J is in a release state, so the DC lamp H2 is not lit. Once power cut, H1 goes out, and the LSE's ④pin outputs a low level. At this time, the Transistor VT is conduction, the relay J is pulled in, the power of the illumination lamp H2 is connect, the H2 is automatically lit, and the transition between the two lamps is almost no break Intermittent.

 

Emergency lighting is still an important product required in against fire safety measures. In the event of an emergency, such as an earthquake, fire or circuit failure, the power supply is suddenly interrupted and all light sources have ceased to operate. At this point, it must provide reliable illumination immediately and indicate the direction of evacuation and the location of the emergency exit, in order to ensure the people who are in dark can evacuate
