Description
This technical report is one of a series of supporting documents to CIE 12.2-1977 Recommendations for the Lighting of Roads for Motorized Traffic. It is concerned with the data involved in predicting the performance of an installation, as described in CIE 30.2-1982 Calculation and Measurement of Luminance and Illuminance in Road Lighting.
- Part 1 of the report describes: the preferred form of basic photometric data for road lighting lanterns: intensity tables; isocandela diagrams; polar diagrams; flashed areas.
- Part 2 outlines: additional derived data for an individual lantern which could be of value: description of a lantern in terms of throw, speed and control; utilization factor diagrams; luminance yield diagrams, isoluminance diagrams.
- Part 3 gives: three useful methods of presenting data on the performance of lantern installations: performance tables; performance graphs; layout tables for achieving a specific performance.
- An Appendix gives: information about differences in performance which have been found between installations using lanterns that satisfy the same specification or classification.
The publication contains 39 pages, 15 figures and 1 table.
