Introduction of Fire Emergency Lighting

Fire Emergency Exit Lights

Emergency lighting is a kind of lighting fixture when the normal lighting power failures, and it can effectively lighting and display the evacuation routes or provide continuous lighting and uninterrupted work. It is widely used in public places and the places that need intermittent lighting. Fire emergency exit lights is applicable to fire emergency lighting, and it is the most common kind of fire emergency lighting, it has long emergency time and high brightness with power emergency functions. Fire emergency lighting has the features of small power consumption, high brightness and long service life, there is power switch on the edge of the design, and refers to the remarkable lights. It is suitable for factories, hotels, schools, units and other public places to prepare for power outages for emergency lighting purposes. The emergency exit light is made of f industrial plastic and high brightness light bulb, the color is mainly white, there are two arrows on the surface, the material is not aging, fast heat dissipation and strong impact resistance and other characteristics. Fire emergency exit lighting can be wall-mounted, portable and hanging installation.

Emergency Lighting Category

Emergency lighting can be classified according to work status and functions. By the work of the state it can be divided into three categories: continuous emergency lights. Regardless of whether the failure of the normal lighting power, it can continue to provide lighting; discontinued emergency lights. It works only when normal lighting power failures. Composite emergency lights. Lamp emergency lighting contains two or more light sources, and there is at least a normal lighting power works after the normal lighting failures. According to functions it can be divided into two categories: emergency exit signs lamps: it can clearly indicate the exit, emergency lighting and channel direction, there is text and icons on the lights, the flag surface brightness is 7 ~ 10cd/m2 and text strokes roughness is at least 19mm and the height is at least 150mm; lighting type lamps: in the event of an accident, it can provide necessary illumination to the aisle, exit routes, stairs and the potential danger zone.

v The Composition of Emergency Lighting

Emergency lighting is composed of the light source, the battery (or batteries), light body and electrical parts. It adopts gas discharge light sources such as fluorescent emergency lights also include the converter and its ballast device. Battery should be chosen to meet the following requirements: use incandescent discharge time of not less than 20 minutes, and the use of fluorescent lamps and discharge time less than 30 minutes; the emergency lights with small installation volume should use the nickel-cadmium battery or lead-acid battery, and the lights with a relatively long discharge time may use the large capacity open type batteries. Electrical components including DC and AC converter, the toggle switch to detect circuit performance and ballast components.
