Lighting

  • Lightning

Humans need light not only to see but also for their wellbeing and health

Workplaces need to have as much daylight as possible and be equipped with suitable artificial lighting. The quality of that artificial light depends on various characteristics, particularly illuminance, luminance, glare-free illumination, shade, light colour and colour rendering. The required level of these characteristics varies depending on the visual task being performed. For high-precision assembly work, for instance, high illuminance levels are necessary so that small details can be seen properly. For colour checks, the colour rendering has to be very good, and shadow produced by directed light is required where surface textures need to be seen clearly.

In this practical facility, participants get a vivid impression of how differences in the individual characteristics affect visual perception.
