Ⅰ. What is an explosion-proof emergency light?

Explosion-proof emergency lights are made of LED technology and environmentally friendly batteries, which can provide a certain amount of lighting time in emergency situations. Explosion-proof emergency lights are also called LED emergency lights, indicating that they are the product of LED technology.

Explosion-proof emergency lights are often used in crowded public places in daily life. It has the advantages of explosion-proof and emergency, and can provide continuous lighting without being affected by external factors. Normally, the explosion proof emergency light is closed, and it will only be opened in the event of a sudden power failure in an emergency.

Ⅱ. What are the classifications of explosion-proof emergency lights?

Explosion-proof emergency lights are a kind of lighting products for personnel evacuation or fire fighting and rescue operations. There are many types of explosion-proof emergency lights, which are generally divided according to different classification methods. The types obtained are different. The specific types mainly include the following:

1. Classified according to the form of emergency power supply: explosion-proof emergency lights mainly include self-contained power supply type, centralized power supply type, and letter power supply type;

2. Classification by purpose: Explosion-proof emergency lights can be mainly classified into sign lights, lighting lights, and lighting sign lights;

3. Classification by working method: Explosion-proof emergency lights can be mainly classified into continuous type and non-continuous type;

4. Classification according to the way of emergency realization: explosion-proof emergency lights can be mainly divided into independent type, centralized control type, and letter control type.

Ⅲ. How to connect the explosion-proof emergency lights? What should I pay attention to?

(1) Connection method:

General lighting, like emergency lights, has three lines and three colors:

a. Purple (red): FireWire;

b. Black: zero line;

c. Blue: switch line;

Before wiring, we must think clearly about whether we only use the explosion proof LED tube light in emergency situations or whether we use it when we don't need it at ordinary times.

1. Use the wiring method in an emergency: connect the live wire and the neutral wire.

2. In general, when there is no need for emergency treatment, the gas station explosion-proof lamp wiring method should also be used: connect the switch wire and the live wire to the same live wire, install a switch on the switch wire, and connect the neutral wire to the neutral wire, you need to pay attention Unfortunately, the incoming line still has only one neutral line.

Generally speaking, the explosion-proof emergency lights in our gas stations have three wires, two of which are stripped by us, and one is not stripped. If you want to disconnect the power, you only need to connect the stripped wire. Two wires, if you are open, whether there is electricity or not, you must connect all three wires, one of which is the switch wire, that is, the live wire, two live wires, and one neutral wire.

(2) Matters needing attention:

1. Correctly grasp the characteristics of various wiring methods to avoid blind wiring and cannot play its due role.

2. If the explosion-proof emergency lighting is an integral part of the normal lighting, the three-wire control connection method should be adopted.

3. For multi-storey public buildings, in the absence of a fire control center, the explosion-proof emergency lighting fixtures in each part can be controlled by local switches (single-lamp single-control or multi-lamp control) or three-wire centralized control.

4. For projects with a fire control center, in order to meet the requirements of the fire control center when a fire occurs, the fire and explosion-proof emergency lighting on the fire floor and related floors can be turned on.
