Abstract

Nowadays, light-emitting diodes (LED) have been widely used in real-time traffic information boards, traffic lights and vehicle lights effectively. Even though these devices are successfully used in each of their designated fields, these devices are greatly affected under bad weather conditions such as heavy rain and fog. This study determined which LED colors were affected under fog condition using LED display and artificial fog with 100μm droplet size and various densities. By using fog droplet size of 100μm and different fog densities, it is revealed that reddish yellow (RY) color was the least affected under fog influences base by saturation and brightness evaluation given by the subjects.
