Zonenausleuchtung

Lumen and Lux?

What do the terms ‘LUMEN’ and ‘LUX’ actually mean and how are they related? It is only possible to draw clear conclusions about the subsequent lighting pattern by combining these two terms.

LUMEN = Amount of light, that can produce the light source (LED), thus the light power of the LED

OPTICS = It collects the light from the LED by reflection and refraction almost without loss

LUX = Illuminance, indicates the intensity of the light that arrives at a specific point on an illuminated surface
