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 alight'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. |
