So the illuminance in the light circle is not homogeneous.įor the complete illumination of rooms or specific areas with a minimum illumination intensity, in most cases several LED luminaires are used. Especially in the peripheral areas, the luminous intensity usually decreases.
When using a single light source, it should be noted that the light distribution of many LED spotlights does not always have to be uniform within the beam angle. After a click on the Calculate button you will see the size of the illuminated area and the lux value. Select Lumen to Lux in the calculator and enter 470 as the lumen value, 110 as the beam angle and 6.5 for the distance.
You want to find out how much lux the table is illuminated with. Example: A spotlight with a beam angle of 110° and a light output of 470 lumens is mounted at a height of 6.5 ft above a table.
