18 Calibration Intervals for Luminance and Illuminance Values TC 4-15 “Road Lighting Caculations, Test Data and Measurement” 16 May 2005 / Leon

19 TC 4-15 “Road Lighting Caculations, Test Data and Measurement” 16 May 2005 / Leon The results of Calculations According to CIE 30.2

20 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°. TC 4-15 “Road Lighting Caculations, Test Data and Measurement” 16 May 2005 / Leon Following statements take part in CIE 140 (page: 5);

21 I-table of road lighting luminaire with no symmetry light distribution should be given according to those definitions. TC 4-15 “Road Lighting Caculations, Test Data and Measurement” 16 May 2005 / Leon

24 TC 4-15 “Road Lighting Caculations, Test Data and Measurement” 16 May 2005 / Leon The results of Calculations According to CIE 140

25 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.
