Radiation characteristics

Beam angle

Probably the most important advantage of modern LED lighting technology over conventional lighting is the possibility of directing the light by means of optics and directing it to where the light is actually needed.

A positive side effect: if the light is directed sensibly, the lighting installation requires considerably less luminosity (lumens) – and thus also less energy!

When implementing lighting projects, it is therefore primarily a matter of determining the optimal beam characteristics – lumens and efficiency play a subordinate role for the time being.



The following example shows a street scene that is illuminated using a 40 W AREA series spotlight at a mounting height of 8 metres and a wide-beam T4M1 optic.

The luminous intensity distribution curve (LVK) uses lines to show the expected light distribution (beam pattern).

The illustrations of the lighting design provide information on light development, luminous intensity and light distribution. In the false-colour representation, the lux values can be read off in concrete terms. This is important, e.g. for compliance with the lighting requirements of the workplace guidelines (ASR).
