Viewing

In the lighting industry, visual tasks and the appropriate lighting level are often talked about, which means as much lighting that is tailored to an activity. The more difficult a visual work is, the higher the lighting level must be. As the name suggests, it is important to recognize and see things in such tasks, whereby the light/dark contrasts, the color contrasts, the detailedness and the speed of contrast perception and the period play a role.

Examples of such visual tasks range from reading and writing at the desk, to working on the computer to the detailed graphics draftsman - depending on the level of lighting and the brightness must be higher and sometimes a lower is enough. This applies both in the commercial area and in private households, because the eyes can be damaged if the lighting is incorrect.

The area of ​​the visual task, which refers to the part of the workplace, is particularly important for lighting planning, where the actual visual task is provided. The values ​​for the illuminance defined in DIN EN 12464-1 standard also apply in the DIN EN 12464-1 standard. It is also important that the work area of ​​the visual task is always a bit brighter than the surroundings around it.
