For commercial and industrial structures, emergency lighting is a must-have feature. Their major function is to brighten the space and mark the location of emergency exits so that employees may safely depart the area. Emergency lighting, which illuminates a light in multiple directions, is typically used in office buildings and passageways near emergency exits or on sheds.
They offer a backup source of illumination in the case of a power loss in a building or location. Choose from our selection of emergency lights to find your best option. We are constantly updating our product variety to provide you high-quality items from prominent companies.
What are emergency lights
In its most basic description, emergency light is a battery-powered lighting device that turns on automatically when a facility loses electricity or a lighting circuit breaks.
Federal, provincial, and/or association regulations and requirements require emergency illumination. These are the result of those governing authorities’ intention to improve safety and security along egress routes in residential, commercial, and industrial regions.
A continuous and uninterrupted path of egress refers to a method to depart a building, structure, or place. Buildings or sections of buildings must have sufficient illumination on escape corridors to comply with various safety requirements. In the case of an emergency, these must be well-maintained and well-lit.
Types of Emergency Lighting
- Maintained Emergency Lighting: These lights are meant to be used regularly in non-emergency settings. They run on the mains until it goes out, at which point they switch to a backup battery. Emergency lights are typically utilized in public facilities such as shopping malls or movie theaters where patrons may be unfamiliar with the layout.
- Non-Maintained Emergency Lighting: These lights are powered by a backup battery and are only turned on in an emergency. They are often utilized in workplaces and locations where the occupants are familiar with the layout without the usage of maintained illumination. Many public buildings will have emergency lighting that is both maintained and unmaintained.
How to choose emergency lighting
If you need lights for an office or industrial area, a simple non-maintained configuration should suffice.
If you’re searching for lighting for a facility with a lot of visitors who aren’t familiar with the layout, you should consider installing both maintained and non-maintained emergency lights.
There is no legal requirement to install maintained or non-kept lights, but you must have enough illumination in the event of a power outage.
How do emergency lights work
The LED bulb is powered by an internal battery that charges itself when it is turned on when electricity is available. When the electricity is turned off, this bulb with a high voltage jumps into action and lights the room. While LED lights have a lumen output of 100 lumens per watt when there is power, they have a lower lumen output of 40-50 percent when there is no power.
When the electricity goes out, the AC power goes out with it, thus the backup battery unit kicks in and supplies power to the lighting system (this is called DC power). The emergency lights batteries must be completely charged within 24 hours once AC power is restored.
LED-based automated emergency lights have been shown to provide enough lighting for extended periods. You will have a light-sensing function with automatic emergency lights. This will ensure that you have access to electricity in the event of an emergency. Lightning inspection services should be performed once a month to keep an eye on these emergency lights.
For enough power supply, numerous components are needed to create automated emergency light circuits. They are as follows:
- Regulators of voltage
- Light-sensitive resistors
- Transistors
- LEDs with high brightness
- LED Batteries in Red
- Transformers that reduce voltage
These components are used to make automated emergency light circuits, however, their quantities may vary. When connecting these components, take care to ensure that no AC or DC current flows between them. If the current passes between them, the circuit will be blown.
Benefits of emergency LED Lights
Automatic emergency lights provide several advantages. They are:
- Automatic emergency lights are simple to set up and need only a few steps.
- Components for automated emergency light circuits are readily accessible and reasonably priced.
- When it comes to energy conservation, they are seen to be the finest option.
- When standard lights fail, these lights will automatically switch on. As a result, you won’t have to struggle in the dark.
- As soon as the regular light and power return, the battery begins to charge.
- When compared to regular lights, the automated emergency lights are quite bright.
- When the battery is fully charged, it will immediately cease charging due to its inherent battery charging features.
How long do emergency lights last
All emergency lights and lit emergency exit signs are powered by a battery. These batteries are rechargeable to ensure continual preparedness and functioning of the emergency light. The emergency light’s circuitry charges the battery and ensures that it remains charged.
The following are the two types of batteries used in emergency lights:
- Lead-acid sealed batteries (the same type used in cars)
- Batteries using nickel-cadmium
The earliest rechargeable technology is sealed lead-acid batteries. They’re nicknamed lead-acid because they have acid-soaked lead alloy plates. The acid dissolves the plates, releasing charged electrons that produce electricity. Lead-acid battery technology has evolved significantly, enabling totally sealed systems that do not require the addition of water to maintain the acid level. Steel enclosure emergency lights typically utilize lead-acid batteries, whereas thermoplastic housing emergency lights use nickel-cadmium batteries.
Before changing the battery in the emergency light, make a note of the previous battery’s type, voltage, and amperage. With a few exceptions, sealed lead acid and Nickel Cadmium are the most common internal power sources for most lights.
Conclusion
A battery backup is included in LED emergency lights. In the case of a power outage or blackout, they can continue to provide illumination. In these instances, emergency lights give at least 90 minutes of illumination, which is ample time to safely leave a building. So you can get this important component for your home from your trusted brand Walton.
