A GUIDE TO LED EMERGENCY LIGHTING

LED Emergency lighting is usually meant for emergency situations where the primary power supply gets disconnected and every normal illumination fails. This could result from a power cut or a fire outbreak. It’s essential that LED emergency lighting automatically operates fully and provides sufficient illumination to enable all occupants to leave the premises safely.
So, if you are considering LED emergency lighting system, here is all you should know:
LED Emergency Lighting: The basics
Most buildings nowadays incorporate sophisticated LED emergency lighting fixtures installed during construction; the design of equipment being chosen by the architect as per the current local authority requirements as well as Building Regulations. Emergency LED lighting is often sub-divided into standby lighting and emergency escape lighting.
Cost matters
Generally, the decision to utilize a self-contained LED Emergency Lighting system or a central battery will probably be determined by cost. If an installation is durable and has low maintenance requirements, then central batteries, though quite expensive, might be ideal for larger projects. Typically, costs and luminaries are major issues of concern, especially on smaller jobs, and it’s this criterion that makes the self-contained systems more popular.
LED emergency lighting driver temperature
Ensure that your LED emergency lighting has been subjected to aging plus electronic load tests. This helps to ascertain whether the LED emergency lighting panels can withstand excessive temperatures. This guarantees performance, safety, and stability.
Emergency escape lighting
Emergency escape lighting refers to that part of the emergency lighting system, which supplies illumination for the safety of persons vacating a location or attempting to end a potentially hazardous process beforehand.
Standby lighting
Standby lighting is often provided to allow normal activities to continue substantially without being changed.
Consultation and design
The first thing to do when installing LED Emergency Lighting escape illumination is consultation and design. Both the fire risk assessor and the designer should meet and make comprehensive decisions on where the system is required and chalk up a plan illustrating the type of power supply, the locations to be covered, facilities, duration, and mode of operation.
The next step…..
Having decided on the type of LED emergency lighting system you’d like to install, then go ahead and choose specific positions for the lighting signs and units within specific premises. This will then help you choose the right equipment. Remember, emergency LED lighting signs should be carefully sited in order to create clear exit routes that lead to the ultimate exits from the building. Where the exit isn’t identifiable, a visible sign should be utilized instead of a lighting unit. Special concern should be paid to directional changes, individual stairways, floor level changes, corridor intersections, plant rooms, and toilet areas. Access to firefighting equipment as well as fire alarm call stations should be properly illuminated.
Mode of operation
Mode of operation is a vital factor to consider when choosing LED Emergency lighting systems. Thus, you should take into considerations principle factors like maintained or non-maintained. The use of the premises in question determines whether to go for a maintained or non- maintained LED Emergency Lighting system.
LED Emergency Lighting: The advantages
• Installation is extremely fast and affordable
• Low hardware material costs
• Standard wiring material might be used
• Reduced maintenance costs
• Burn-through will automatically fulfill the need for luminaries to be lit
• No unique sub-circuit monitoring requirements
• Increased integrity and efficiency
LED Emergency Lighting: Disadvantages
• Testing requires isolation
• With varying environmental conditions throughout the system, the batteries might be severely affected by high or low ambient temperatures
• Battery life is often limited to four years, depending on the application
Bottom line
LED Emergency Lighting systems have become very popular these days- thanks to their low energy consumption, efficiency, and flexibility. However, before you rush into getting your LED Emergency Lighting system, it is vital to understand the basics (what they are and how to choose the best). The above guide will help you in getting the best.

Evolution of Lighting Technologies

Incandescent Light Bulbs

Lighting has evolved over the years. Let’s find out how it evolved. As we know Edison invented it to transform our life. By the way, you will be surprised to know that he also developed the first electric meter.


While Edison was working on the whole lighting system, there were many inventors that were putting their efforts to make several advancements in order to improve the filament manufacturing process. As a result, a dramatic change in the technology came in 1904, when European inventors invented tungsten filament. The new tungsten filament bulbs were quite significant and have the ability to last longer. 

The saga continues and 1913 became yet another remarkable year. This is the year, when Irving Langmuir pointed out that placing an inert gas like nitrogen inside the bulb can improve (double) its overall efficiency. By the 1950s, inventors and researchers had only figured out how to convert about 10% of the energy the incandescent bulb used into light. They began focusing on other more innovative lighting solutions.

Emergence of compact fluorescent light (CFL)

 

Furthermore, the oil crisis of 1973 forced lighting engineers to develop an efficient fluorescent bulb. 1976 was yet another significant year in the history of lighting when Edward Hammer of General Electric pointed out how to bend the fluorescent tube into a spiral shape. This was resulted in the development of the first ever compact fluorescent light (CFL). Early CFLs hit the market in the mid-1980s; however, they were bigger in size and somewhat bulky, as a result they didn’t fit well into fixtures.

It must be noted that CFL uses about 75 % less energy than incandescent and last longer say about 10 times longer.






Era of light-emitting diode (or LED)

One of the fastest emerging and developing lighting technologies today is the light-emitting diodes (or LEDs). Initially, they were used in a wide variety of applications including traffic lights, flashlights, etc. Since then, LEDs have evolved, no wonder, today, it is the most efficient lights than any other traditional lights. And the reason is simple - they have many advantages over incandescent light sources, including lower energy consumption, longevity, performance, robustness, compactness and much more.


Facts:

LEDs contain no mercury, and a recent Energy Department study determined that LEDs have a much smaller environmental impact than incandescent bulbs. (source – energy.gov)
The LED was invented by Nick Holonyak Jr. in 1963 while he was working for General Electric. (source - phoenix.gov)


A business, such as a warehouse or large hotel, can save up to 70% of its electricity costs by switching to LED lights with motion sensors...and receive a payback on the capital outlay within two years. (source - http://www.energysavingtrust.org.uk/blog/future-led-lighting-gets-brighter)

Today, LEDs are used in the widest possible applications from aviation lighting, automotive headlamps, advertising, general lighting, to traffic signals.
