Performance evaluation of a LED-IT-sensor integrated streetlight system in USN

Abstract

Recently, with the issue of a Green-IT technology, various studies on a eco-friendly luminous source that can reduce Carbon discharge and increase energy efficiency are actively progressed all over the world. Especially, with the problems of high oil price and environmental pollution, LED has made a great attention as a new luminous source that can replace the existing incandescent bulbs and fluorescent lights. In this paper, we propose a LED-IT-Sensor integrated streetlight system in USN that becomes more intellectual by combining the low power consuming, high efficiency, and high luminous LED module with a complex sensor module of temperature, humidity, illuminance and motion detection sensors. The performance of the proposed LED-IT-Sensor streetlight system is evaluated in terms of power savings and safety at the fields constructed as a test-bed under several suggested scenarios. Finally, we know that the proposed LED-IT-Sensor integrated streetlight system can maximize the energy savings efficiently with central monitoring system and selective remote dimming control by connecting it to the wireless ubiquitous sensor network (USN) using a Zigbee module. © 2012 Springer-Verlag.
