Task lighting
Task lighting is a term used to describe the illumination of a task area within a workplace (e.g. a desk, a counter).
It is used to support a visual task, which expresses the perceptual performance required from the eye to perceive an object. The grade of difficulty of the task increases with the diminishing of colour contrast, size and detail.
There are many standards for workplace lighting that take the visual accuracy and detail of the task into account.
Tip from a lighting designer
Lighting should meet the demands to fulfil specific visual talks, but should not be limited to it. Lighting that is designed just to meet the norms would be cutting it short. Human perception is far more complex and the potential for lighting is far greater. As lighting designers we plan lighting for the visual task, to guide the visitor, to create identity and well-being in indoor spaces.
