Human Centric Lighting/4. HCL in industrial plants

1. Why is Human Centric Lighting (HCL) so important in industrial plants?

Safety, health and productivity are the keywords that summarize the benefits of a technologically up-to-date lighting system in an industrial environment.

These benefits are also at the basis of the revolutionary Human Centric Lighting approach that puts people and their wellbeing at the centre of lighting design.

Good lighting is an essential requirement to ensure safety in the workplace and the LED technology represents a major leap forward in this direction. The new high-efficiency sources allow having all the light you need to work in full safety, cutting down consumptions, without wasting energy and polluting the environment.

The high colour rendering of LED sources makes several industrial processes easier to perform while boosting productivity. This also adds up to the biological effects of the spectrum lighting studied in Human Centric Lighting. The different colour temperatures, which are correctly setup and duly managed across the entire workday, produce a favourable effect on workers’ circadian rhythm, decreasing the stress accumulated during the workday with positive psychological effects.


Automation, information technology, the attention to the environment and energy consumptions have deeply transformed factories and manufacturing environments in general. The old lighting systems are now completely obsolete, not only for their lighting performance, but also because lighting has taken on new tasks.

With the new LED lights we are closer to the Human Centric Lighting approach that allows using all the possibilities of the LED technology to get the maximum result in different environments making up a manufacturing plant.

In fact, a lighting system in an industrial plant have many and differentiated goals depending on the areas to be illuminated.

The figure below shows the main goals of Human Centric Lighting in different environments of an industrial complex.


2. How to exploit the advantages of HCL in industrial plants?

According to Human Centric Lighting criteria, there are three effects of lighting to be considered: visual, biologic and emotional.

Starting from this assumption, a lighting system based on Human Centric Lighting criteria is capable of improving the safety and the quality of the workplace.

In addition to complying with safety standards, this type of lighting system can use light to emphasize danger zones, highlight specific hazards, and increases the safety of access roads and routes inside the industrial plant and the warehouses.

For the wellbeing of workers, we use glare-less fixtures with the lowest possible level of flickering, and the possibility to use lighting control systems to obtain the best balance with natural lighting and prevent excessive contrasts in different indoor areas.

In many cases, industrial plants have working shifts that span the full 24-hour day. By working on the blue component of light we can improve workers’ concentration at the beginning of the shift and help them relax once work is over by gradually reducing the stimulus.


3. How does it comply with lighting regulations?

The lighting regulation in the workplace has changed over the years. New concepts have been introduced that go beyond the mere lighting performance of fixtures and also take into account of the visual comfort of workers in addition to safety requirements.

EN 12464-1 standard, updated in 2011 (read also HCL in offices), defines the lighting levels for a visual task (the work area), the area immediately surrounding it and the background area that must be illuminated proportionally to the value required for the visual task.

Moreover, the standard also considers lighting distribution which is calculated with well-defined criteria, and lighting uniformity, also for walls and the ceiling. To reach a balanced and pleasant lighting, in fact, you need to consider all the components of the environment and the light reflections.

Other values considered by the new standards are cylindrical illuminance and modelling, as a way to allow the correct viewing of people and their communication.

Glare and the lighting of rooms with video displays are governed by specific standards.


4. Which lighting fixtures can be used to apply HCL in industrial plants?

To develop an industrial lighting system which is based on the Human Centric Lighting approach, there are several solutions that range from liquid-tight fixtures, high-bays, outdoor lamps and street lighting to spotlights and recessed lamps for entrances and transit areas, without forgetting emergency lighting.

To select the best luminaires for industrial plants we must carefully consider some basic features to be sure the system is functional and reliable over time.

  • High-quality materials (a LED lighting system can keep its original performance over time only if fixtures are made with quality materials)
  • Robustness and reliability (degree of protection suited to operate in industrial environments)
  • Energy-saving (savings are considerable compared to old lighting fixtures and they can be further increased with lighting controllers)
  • Easy maintenance (particularly important for indoor areas with specific environmental conditions, like the ones in industrial processing plants)
  • Special products (to be used in special processes, such as for example in the food sector or in extreme temperatures and in rooms where corrosive agents are used)
