Question

Quizplus · Accepted Answer

LED-based traffic signals will reduce energy demands from neighborhood infrastructure. LED stands for light-emitting diode. LED is a semiconductor light source used in many devices and is increasingly used for lighting. LED-based lighting is high in efficiency, as measured by its light output per unit power input. However, in areas that receive a lot of snowfall, it has been observed that LED-based traffic signals fail to melt the snow that obscures them, which is an advantage of incandescent signals.
