研究目的
Investigating how the measurement accuracy of luminaire luminous intensity distribution curve impacts the accuracy of road lighting calculations.
研究成果
The research concluded that programs supporting the lighting design process yield more realistic results when the luminaire has an accurately determined luminous intensity distribution curve. A slight reduction in photometric testing accuracy does not significantly affect calculation results, but further reductions necessitate modifications in luminaire arrangement and can adversely affect energy performance indicators.
研究不足
The study was limited to a few luminaires and specific road types, which may not cover all possible scenarios in road lighting design.
1：Experimental Design and Method Selection:
The study involved performing lighting calculations for several typical road luminaires with different accuracies of luminous intensity distribution curves.
2：Sample Selection and Data Sources:
Several luminaires from well-known manufacturers with high accuracy light distribution were selected.
3：List of Experimental Equipment and Materials:
The luminaires selected included Teceo 2 (Schreder), BGP625 (Philips), Megin L (OMS), and Streetlight 20 (Siteco).
4：Experimental Procedures and Operational Workflow:
Photometric files were simplified to limit the accuracy of determining the luminous intensity distribution, creating several files of different accuracy for each luminaire.
5：Data Analysis Methods:
The Dialux Evo software was used for photometric calculations to analyze how the accuracy of photometric data affects lighting parameters and energy performance indicators.
