Evaluation of Artificial Lamp which correlate real sun for SAT of paint color

Abstract

For evaluation of reflective thermal-insulating paint color, we examined the artificial lamp as heat source which related to the sun. The testing method is JSTM-6100(2003). SAT meter measured various colors at temperature to reach 80°C. As a result, the correlation between sun and metal halide lamp was R^2=0.91(error 4.9% to sun) and halogen bulb was R^2=0.75( error 10.8%). Metal halide lamp was good experimental light source for evaluation of thermal property of various paint color.
