Abstract

For recent years, LED lighting has become a very popular issue in illumination. At street lighting, it provides a choice of energy-saving and longer lifetime. The most important benefit is LED street lighting could change color-temperature depending on weather or traffic conditions. In this experiment, under 5 levels fog conditions, the chromaticity stability of white LED street lights with different color temperatures was conducted, and the results showed that the color temperature of white LEDs affects the chromaticity after different penetration distances.
