An innovative and future-oriented LED lighting fixture for areas at risk of explosion and fire

1. Introduction
 
LifEx lighting fixtures are the first LED native linear fixtures, featuring an innovative design by Cortem Group, created in response to customer requirements.
The product architecture has been carefully designed. The aim is to manage the full product lifecycle optimally as part of a circular economy, and maximise the product’s useful life. The result is a compact, lightweight lighting fixture that is easy to install, while also being robust and long lasting.
They feature a high-quality anodised aluminium body and a clear part in satin finished glass which is resistant to impact and high temperatures. They have an innovative bracket mechanism, with no fixed interaxis spacing limitations, which makes them easy to install or retrofit and means the lighting fixture can be rotated to -30°/0°/+30°.
The LifEx range comes in different lengths with a wide array of voltage and power specifications. The range has been optimally designed and certified according to the installation zone and, in addition to passing all tests required by the regulations, it has passed additional mechanical and electrical tests such as vibration testing, soft start, surge testing and more.
 
 
The connection of our LifEx series lighting fixtures can be made using one or two ISO M20x1.5 'Ex e' cable glands with single seal. Furthermore, the opposing inlets allow the in/out connection in case there is the need to install multiple lighting fixtures on a single power line.
The LifEx series is ATEX, IEC Ex and TR CU certified.
 
2. Lumen output up to 15.500 lm
 
As regards the electrical and photometric characteristics, the use of LED technology and high-power LED strips has made it possible to reach 15,500 lm as lumen output, with high efficiency and a guarantee of durability. The LifEx series has a light beam opening of 120°, falling within the limits dictated by the most recent light pollution standards, and a color rendering index higher than 80.
The design of the lamp body, in addition to being functional to the duration of the system, gives the equipment very high light emission in relation to the maximum surface temperature (T), a very important factor for the installation of lighting fixtures in places with explosion hazard, containing gas or dust at low ignition temperature.
LifEx series lighting fixtures, featuring an immediate ignition (Instant Restrike), can be effectively connected to automatic ignition systems in case of low light, allowing the use only in the periods of time really necessary and, consequently, further savings in energy costs.
 
3. Innovative bracket system
 
LifEx lighting fixtures have been designed to make installation quicker and easier thanks to an innovative bracket mechanism, with no fixed interaxis spacing limitations, which makes them easy to install or retrofit and means the lighting fixture can be rotated to -30°/0°/+30°. The brackets can be inserted at any point on the body of the lighting fixture before its installation so as to allow easy replacement of obsolete or no longer functional pre-existing installations.

4. Zone Proof design for installation
 
LifEx series lighting fixtures are available in two different configurations for different application needs: LifEx-ME and LifEx-MN.
 
The "ME" versions are designed to be used in ATEX areas classified as "Zone 1" and "Zone 21", that is where the equipment installed must guarantee a high level of protection both in the presence of mixtures of gases, vapors and mists (Zone 1) and in the presence of combustible dusts and particles (Zone 21). LifEx-ME has an EPL (Equipment Protection Level) Gb, Db.
This safety is guaranteed by a combination of protection methods ‘Ex db eb mb’ for gas and ‘Ex tb’ for dust.
 
The "MN" versions are designed to be used in ATEX areas classified as "Zone 2" and "Zone 21", that is where the equipment installed must guarantee a normal level of protection in the presence of mixtures of gases, vapors and mists (Zone 2), and a high level of protection against dusts and combustible particles (Zone 21). LifEx-MN has an EPL (Equipment Protection Level) Gc, Db.
This safety is guaranteed by the ‘Ex ec’ protection methods for gases and ‘Ex tb’ for dusts.
 
 
5. Be inspired by nature to innovate 
 
 
“Our design objective was right from the start to create an innovative linear lighting product, native to LED and, therefore, designed around the needs of the light source – says Cristiano Decorte - R&D Manager of Cortem Group. 
To achieve this, we have relied on biomimicry, a cross between biology and technology, whose goal is to study the biological and biomechanical processes of nature, considering them a source of inspiration for the improvement of human technologies.
For the design of the LifEx section we were inspired by a natural element and, in particular, by the Ginkgo Biloba leaf. The same name LifEx recalls at the sound level LEAF. We also wanted to represent this link between the product and nature in the logo designed for the product.
For the lighting sector, one of the key objectives is to significantly reduce its environmental footprint. In the design we took this aspect into consideration by eliminating about 70% of the components that made up a traditional lighting fixture, using native LED technology, which produces a low amount of CO2, and recyclable materials, such as the aluminum and glass of the body, as well as most of the internal components. The high energy efficiency allows to reduce consumption and, therefore, the pollution produced".
