The quality of lighting in work spaces is a very complex and multifaceted topic.
Each person and each activity has different needs and, consequently, in the architectural lighting of the workplace there must be both physical and psychological well-being. This means allowing people to peacefully carry out their activities while safeguarding their visual health.
An adequate amount of luminous flux must therefore be provided and the conditions that allow the activities to be carried out in the best possible way with positive contributions to the production of the entire company must be created.
The appliances must be installed at the right height in order not to dazzle or constitute an obstacle, following the regulatory parameters. Comfort, visual performance and safety are the main lighting requirements considered in the UNI EN 12464-1 standard “Light and lighting – Lighting of workplaces – Part 1: Indoor workstations”.
Among the parameters considered to define the lighting environment are the light distribution, the direction of the light that illuminates the interior spaces, the variability of the light (light levels and colors) and the glow. To create a balanced distribution of light, it is necessary to take into account the brightness of all surfaces and certain reflections and contrasts, also avoiding that intense light sources cause glare and, in this case, provide adequate shielding. UNI EN 12464-2 “Light and lighting – Lighting of workplaces – Part 2: Outdoor workplaces” is also important.
