The results of Calculations According to CIE 30.2

In the (c;) system of coordinates, luminous intensities will be required at the

angular intervals stated below.

For all luminaires the angular intervals in elevation () should at most be 2.5

from 0° to 90° plus the permissible maximum field angle of elevation minus

the measurement angle of elevation, for the luminaire. In azimuth the

intervals can be varied according to the symmetry of the light distribution

from the luminaires as follows:

- Luminaires with no symmetry about c = 0° – 180° plane; the

intervals should at most be 5°, starting at 0°, when the luminaire is in

its measurement angle of elevation and ending at 355°.

Following statements take part in CIE 140 (page: 5);

I-table of road lighting luminaire with no symmetry light distribution

should be given according to those definitions.

The results of Calculations According to CIE 140

According to CIE 140, the observer’s eye height 1.5 m above road level, is

positioned transversely a quarter of road width from the carriageway edge,

and longitudinally at a distances in meters of 2.75 (mounting height: 1.5) in

front of the field of calculation.

In EN13201 Part: 3, it is stated that “the observer’s eye, is positioned in

the centre line of each lane in turn” by keeping all other parts same.
