If you're browsing through your daily business, you'll notice that you don't even know where it can see emergency lighting. It can be found in offices, stadiums, shopping halls, to name a few. Next time you are in the hotel lobby, there are multiple LED spotlights on the ceiling, please pay attention to the one with green LEDs next to it. That is your emergency light!
But where is emergency lighting working, why is it important?
The definition is as simple as the title suggests - emergency lighting will be put into operation when the building's main power supply fails. It provides lighting to allow passengers to safely find their escape. However, emergency lighting systems are becoming more and more complex, and while continuing to evolve, quality and safety must remain an essential feature.
The importance of emergency lighting
The importance of emergency lighting is obvious: in potentially life-threatening situations, such as damage or even lack of visibility, no one should be under additional stress.
As a consumer, how do you ensure that emergency lights operate as required in an emergency?
The question that professionals often ask is, is it tested?
When I saw the BSI kite logo, I knew that manufacturers care about quality and understand the importance of justifying product products for the benefit of the public.
Interesting emergency lighting products, testing and common faults:
Emergency lighting can be provided in many different forms.
Stand-alone: Means a system with a light source, lighting controls (called control devices, ie LED drivers and battery chargers) and a local battery that is charged by the building's main power source and provides illumination in an emergency. This can be called an emergency luminaire.
Central Battery System: As an alternative to the above battery system, the building contains a central point with a battery pack that is active in the event of a normal power failure, which provides emergency units with lighting units throughout the building. electric power.
Emergency lighting often has two modes of operation. The maintenance mode means that the lamp is still running when powered from the mains and then in emergency mode again. The second one is non-maintained. As you can imagine, the lights will only run when the system is in an emergency.
Another element of emergency luminaires is the light source. Traditional fluorescent lamps are the most common. However, with the recent cost reduction, emergency LED lighting is booming
Finally, another interesting product on the market is the automated test system. This provides support for intelligent systems in the field of emergency lighting. These systems are a central point that constantly monitors emergency lighting, provides fault detection data and automatically performs the required safety checks (usually manually)
However, the intelligent lighting control system can incorporate a "self-test" that also performs the required safety tests, but is an independent control that does not require a central control point.
All of these different variants should be tested in accordance with relevant standards, as detailed.
The most common failure of emergency lighting we see in the relevant regulations is the mark.
Although it may seem trivial, it is an essential part of these systems. I would urge each manufacturer to take the time to understand all the requirements of the system. The goal is to ensure safety and to ensure that end users have critical technical product grades – such as power and operating temperature – to ensure that the product fits their installation location.
A common and very important non-compliance is an emergency light that does not last for a battery value that is declared for hours. What is the manufacturer's statement of the duration of the "emergency mode" (this is the length of time the battery is turned on). 3 hours is the most common declared value - and is the minimum requirement in the GULF area.
So what are the factors that cause these systems to fail?
Under normal environmental conditions, the system typically meets a rated duration of 3 hours, but as a standard requirement, emergency lighting must operate C at low temperatures (typically 0 ° C) and high temperatures of 40 ° C to 60 °.
The temperature depends on what the manufacturer declares the product to run in, because you can see that it is important information that needs to accurately meet compliance.
