Abstract :
While light-emitting diodes (LEDs) are a very efficient lighting option, whether phosphor-coated LEDs (PC-LEDs) are suitable for street lighting remains to be tested. Correlated color temperature (CCT), mesopic vision illuminance, dark adaption, color perception, fog penetration, and skyglow pollution are important factors that determine a light´s suitability for street lighting. In this paper, we have closely examined the lighting performance of LED street lights with different color temperatures and found that low-color-temperature (around 3000 K) PC-LEDs are more suitable for street lighting.
