Luminance coefficients

Post by jason.fc » Fri May 04, 2018 5:05 pm

How can I show the luminance coefficient values used by DIALux evo in calculating the street luminance tables?
Thanks

Hi

As luminance values in street lighting are obtained by

, I would like to know the rk(tan e,B) values used in computing for instance the 0.80 value in cell (10.500,5.500) in the luminance table

Thanks and best regards

Dear jason.fc,

The interim results from the r tables are not included in the output. There you can only see the final result.

We use the following r-tables:

- For normal road surface: CIE 30 - 2 82 Calculation and Measurement of Luminance and Illuminance in Road Lighting

- For wet roads: CIE 47 79 Road Lighting for Wet Conditions


Kind regards,
