The aim of this research is to compare the influence of two different luminous sources (incandescent light and LED light) on perceived contrast of objects in a disability glare context. About 25 subjects were involved in an experiment in order to monitor the variations in their contrast perception threshold, with and without glare sources, using a calibrated computer LCD display. In this first phase the spectral influence is investigate. Typical applications of this research results, could be road and tunnel lighting requirements on disability glare restrictions when LED sources are used.
