Experimental Verification of Performance Method for Vehicle Headlighting Systems in China

摘要

For the sake of assessing the photometric performance of vehicle headlights with a standardized,accurate and reliable method,the CIE 188 Technical Report specifies the methods to assess the photometric performance of vehicle headlighting systems.In order to verify the rationality of the methods described in this report and the suitableness of the methods if used in China,three subjective rating tasks were conducted.The comparison between the results calculated according to CIE 188 Technical Report and subjective rating scores indicated the necessity of further research of the methods described in this report before they were promoted in China.
