Why LED in hazardous areas?

Why LED in hazardous areas?

LED technology is becoming more and more popular in the explosion proof market as a solution capable of radically changing the future of industrial lighting thanks to its characteristics of high luminous efficiency and low consumption (W).

LED technology applied in potentially explosive atmospheres offers important advantages compared to traditional lighting sources.

LED lighting is energy efficient and extremely durable. A LED lighting fixture will generate the same illumination as a traditional lighting fixture by using less energy input (up to 90% less). Usually, a LED lighting fixture produces 200 Lumens per Watt, while a fluorescent lamp typically produces around 90 Lumens per Watt. This clearly states that energy savings has always been the main driver of the development of LED lighting.

LED lighting fixtures have an average operating time of more than 80.000 hours, in some cases more than 100.000 hours, at acceptable levels. This long service life is particularly relevant within the hazardous area environment where maintenance of lighting is dangerous and extremely costly. Maintaining traditional light sources means shut down the plant in order to change the lamps. For this reason, many plants do not perform this maintenance until absolutely necessary, usually when safety has already been affected by the lack of working lighting. The costs involved can be significant also considering the shut down of the production.

The above characteristics of efficiency and durability positively affect on reducing maintenance costs and on a higher level of safety by providing a safe environment for workers.

Furthermore, LED lighting has a CRI (Colour Rendering Index) rate of about 70-97. The colour rendering index is a measure of how accurately a light source renders colour. For instance, sunlight, which shows real colours, has a CRI of 100. This means that LED lighting allows to perceive colours how they really are.

Since LED technology is constantly evolving, it is important to choose a reliable partner like FEAM that can boast a consolidated experience and a proven technological know-how throughout the world.

FEAM is a manufacturer of LED lighting fixtures in copper free aluminium with a dedicate aluminium heat sink technology to reduce the physical temperature of the fixture, this improves durability and further reduces any potential risk of explosion. FEAM LED lighting fixtures have a stronger housing than traditional fixtures with a tempered glass that encase sparks and other potential ignition.

Choosing a partner like FEAM means working with a company who pays particular attention to reliable products. Reliability is direct bound to certification, traceability, warranty and lighting design.

Certification: FEAM’s LED products are certified according to the main international standards such as: ATEX, IECEx, INMETRO, TR CU, Rina and Russian Marine Certificate.

Traceability: FEAM can provide traceability on all its products and components parts used within its products.

Warranty: There are suppliers who offer 10-year warranty to their products without knowing where or how these products have been installed. Before offering any extended warranty, a reputable manufacturer must know this information; this is relevant in hazardous areas where harsh environments and/or wrong installations can affect on the right operation of LED lighting.

Lighting design: One of the most confusing aspects of luminaire selection is that some manufacturers will quote luminaire lumens and others will quote just lumens or lamp lumens. Luminaire lumens are a measured figure of the light produced by the luminaire once the LED is installed inside (luminaire polar diagram). This considers efficiency losses through the diffuser of the luminaire and any other aspect of the luminaire design which may affect its efficiency. Lumens or Lamp lumens are light outputs taken directly at the led source and do not include any losses or inefficiencies of the luminaire.

FEAM can supply the luminaire polar diagram in order to check correctly the values of the luminous flux and other lighting characteristics.

Furthermore, one of the most important aspects of a lighting system is its initial design. Many manufacturers can supply a lighting design which is for an office or warehouse… but a design for hazardous area is very different. Hazardous locations have multiple obstacles which can impede the effectiveness of the lighting. A typical example would be a chemical site.

The advent of modern design software allows manufacturers to produce lighting designs which can show, in 3D, the space to be lit and give a more accurate representation of what the end user needs for a given space.

FEAM is involved in the development of state-of-the-art LED solutions that meet the most complex customer requirements. FEAM supplies a complete range of LED lamps for hazardous industrial areas to ensure efficiency, reliability and constant safety. This range includes: lighting fixtures, floodlights, exit lighting fixtures, warning lights, weatherproof street luminaires, lighting fixtures for LED tubes.
