Special Eulumdat file sample

F

Frank Knappe

Hello!

I'm looking for a sample Eulumdat file where line 26
Number n of standard sets of lamps (optional, also extendable on
company-specific basis)

has a number different to one. Especially I'm interested how this will
affect the following line.

What was the intention of this line?

Hi,
the line 26 is not very often different from 1. The idea is, that a
luminaire can be used with different sets of lamps with different
luminous flux, power and colour but not changing the luminous intensity
distribution. For example a downlight for incandescent lamps with E27
socket.
You can use in this downlight for example a 40W, 75W or 100W lamp.
All of them have different power and flux. But the shape of the luminous
intensity distribution will not change, because the filament and the
position of it are (more or less) identical.

In our example Line 26 would be "3"

Than we would have three times the lines 26a to 26f, starting with 40W:
1
A60 40W
415
2700
1A
40
1
A60 75W
935
2700
1A
75
1
A60 100W
1340
2700
1A
100

Next line would be 27 direct flux ratio.

Since there is free software like DIALux (www.dialux.com) available with
electronic catalogues of products, Eulumdat is less important. The
manufacturer can put in his electronic catalogue any version of the
fitting including different lamps which can be used.

Thanks.
I've made some test files and they worked. Unfortunately in practise the
situation isn't that easy. For luminaires with fluorescent tubes the
length and also other parameters are changing when a different tube is
installed (i.e. line 13 and others).
