| Abstract | This report presents the measured illumination characteristics of the 66 ECE and SAE type headlaaps examined by N.R.C. ueing the initial goniometer system in the photometric laboratory during 1971 and 1972.
The illumination measurement procedure ie discussed briefly in order to describe the baeic form of the illumination data. Various headlamp characteristics and measurement parameters which are necessary for subsequent utilisation of the data are presented in tabular form. A note is included concerning the storage of the measured illumination datasets for the headlamps.
The intensity mapping procedure for the headlamp is described. The preference for this form of the headlamp dataset over the measured illumination data for use in further illuaination calculations is mentioned briefly. Contour plots of the intensity maps for the various headlamps are utilised to demonstrate the measured illumination characterietics of these headlamps. |
