Test Cases To Assess The Accuracy Of Spectral Light Transport Software

Raphaël Labayrade, Vincent Launay

Abstract: This paper proposes an extension of the CIE 171:2006 test cases dedicated to the assessment of the physical accuracy of light transport packages. While the original methodology is limited to the assessment of spatial light propagation, this paper introduces four additional analytical verification test cases aimed at evaluating the spectral light propagation that is likely to occur in buildings. The spectral accuracy of SPEOS V5¹ light transport simulation program is then assessed. Partial assessment results suggest that SPEOS V5 can correctly simulate the spectral propagation of light in a building lit by light sources featuring arbitrary spectrums (such as LED or OLED).
