How many kinds of emergency lighting are there? What are these lights?

At present, almost all public buildings should be equipped with emergency lighting, which is clearly stipulated in the fire protection measures of buildings. If it does not meet the specifications, the building cannot be put into use. How many kinds of emergency lighting do you have? What are these lights like? Let's have a look.

1. Fire emergency lighting lamps

Fire emergency lights are necessary in all public buildings, mainly to prevent sudden power failure or fire, as a coordinate indicator to evacuate people. They are widely used in shopping malls, offices, hotels, hospitals, underground facilities and so on.

There are also many kinds of fire emergency lighting:

A, there are three kinds of lights under different working conditions, one is a continuous emergency light that can continuously provide lighting, which normal lighting does not consider; The other is discontinuous emergency light, which is only used when normal lighting lamps fail or power is cut off; The third is the composite emergency light, which is equipped with more than two light sources, and at least one light source can provide illumination when the normal power supply fails.

B, there are two kinds of lights with different functions. One is to provide necessary lighting for walkways, exit passages, stairs and potentially dangerous areas in case of accidents. The other is that it can clearly indicate the direction of the exit and passage, and there are signs of words and charts on the lamp.

The marker lamp is a very common emergency lighting with very standard requirements. The brightness of its logo surface is 7 ~ 10cd/m2, the stroke thickness of characters is at least 19mm, then its height is 150mm, and the observation distance is 30m, which is more obvious.

Fire emergency lighting consists of light source, battery, lamp body and electrical components. Emergency lamps using gas discharge light sources such as fluorescent lamps also include converters and ballast devices.

2. Emergency lighting

The second type of emergency lighting is mainly used for emergency lighting in warehouses, cable trenches, roadways and other occasions. It has the characteristics of high efficiency and energy saving, and mainly adopts the fourth generation of green high-power white LED solid-state light source, with high light efficiency, long service life and no need for long-term maintenance.

It is also a very user-friendly product, which can automatically and manually switch emergency functions. Wide voltage design is convenient to use, soft light, no glare, and can improve the working efficiency of operators. The light alloy material of the shell has the characteristics of wear resistance, corrosion resistance, waterproof and dustproof.
