AN APPROACH TO CONTROL AND DISPATCH STREET LIGHTING SYSTEMS WITH NEW DIMMING METHOD FOR LED-EYE SETS

Abstract

This paper presents a new approach to street lighting systems using LED lamp sets, called LED-eye sets. A new dimming method is proposed to regulate lamp sets having some LED eyes that helps to lengthen their life time and lighting stability. This paper also proposes some more solutions to design and operate LED-eye sets basing on dimming method such as using hybrid power supplies, artificial intelligence and smart lighting zone to create intelligent lighting areas. They will help to reduce power consumption from electric grid, ensure a comfort illumination and decrease the effect of artificial lighting to the environment. The proposed dimming solution is verified by an experimental model which uses lamp sets having three LED eyes for each set. Moreover, the haar cascade classifier is used to identify vehicle density in this study that helps to decide on/off control signal for each LED eye. These proposed solutions can be applied to regulate all LED-eye sets and make lighting systems become more intelligent and greener.
