Task area

Task area is the most important space in terms of illumination quality. Here the work itself takes place and at the very least demands constant and sufficient lighting without any disturbing effects such as glare or flicker. The illumination of the task area should take into account the type of work being done, the focus it takes to carry out the task and also other demands. For example graphic-intensive work or any other visually engaging activity requires high-quality colour rendering.

For the designer this means having higher-quality light sources in mind, for the manager it means higher costs and extra care in maintenance. Replacing of the light source with an inferior type during maintenance could negatively affect the quality of the product or service, jeopardizing sales and increasing unnecessary costs.

The standard requires constant illumination level over a task area regardless of quality or age of the lighting system. Special care therefore has to be taken that even older light sources, which diminish their illuminance with age, provide the required illumination level. If necessary, for certain tasks additional luminaires may be needed in the task area.

Technical drawing for example demands not only high-quality illumination with very high CRI, but in many cases also shadow-free workplace. This can be achieved either with additional lighting that diminishes shadow formation or by setting up the task area so that it can be shadow free under the current illumination system.

From the LQS point of view, a lighting solution can either comply with the EN 12 464-1 standard or fail to do so, giving it a mark of either 5 or zero in the ranking.
