Monochromatic Leds For Vision Improvement in Foggy Roads

Abstract

In India, foggy weather creates poor visibility, and this leads to several accidents and slows down normal traffic speed, which may lead to adverse effect on the economy of the country. The probable solution is the use of monochromatic light with other artificial vision system to increase the visibility for the drivers in these foggy areas. There are various kinds of monochromatic lights available in the market. In this study, it has been tried to find out the best working monochromatic LEDs for this particular application. In this study, two types of monochromatic radiation were compared (amber light with 600 nm and green light with 545 nm) with and without the camera-display setup (artificial visual system) for finding out best working system in the foggy area for increasing the visibility. The experiment shows that amber light monochromatic radiation with 600 nm works better for identification of objects. The amber light can be used in front of a car to illuminate the front environment in the foggy weather and increase the visibility. It has been observed that green light monochromatic radiation with 545 nm works better for identification of the source from a very long distance. It has been proposed to install both of these lights with amber and green monochromatic radiation in vehicles to reduce accidents in foggy weather.
