Nominal lighting strength

The so -called nominal lighting strength is understood to mean the average illuminance in a space set up in relation to the middle aging state of the light.

In order to specify the new value for a new lighting system, the nominal lighting strength had to be multiplied by the planning factor 1.25, since this always refers to medium aging. It is measured and given in the Lux.

The nominal lighting strength was then used, for example, in the workplace guidelines, with the appropriate lighting conditions related to a horizontal work surface of 85cm above the ground. For EDP work in the office, 500 lux, among other things, and for drawing offices, the double to Lux were recommended.

All of this was important to determine the right lighting conditions, since the only way to do the visibility could be carried out without too much effort for the eyes.

However, the nominal lighting strength is no longer used in the lighting standards. Instead, so-called maintenance values ​​for the values ​​of the illuminance are now given in the DIN-EN-NORMEN.

In these new values, the decline in the illuminance is also taken into account due to pollution and aging of the light sources.
