Bi-Level Demand-Sensitive LED Street Lighting Systems

EW-201017

Objective

The objective of this project is to design, develop, and deploy an energy-efficient and demand-sensitive light emitting diode (LED) street lighting system as a retrofit to an existing system. The technology is based on LEDs that allow dimming as well as traffic sensing capability through a centralized controller. The smart server and a network management center are integral parts of the demand-sensitive street lighting system, enabling power consumption monitoring, control, and failure identification of each light fixture.

Technology Description

Elements of the demand-sensitive LED lighting system include LED light fixtures, a streetlight controller, traffic sensors, a smart server, and a network management solution. Each of these elements is mature and commercially available today. However, efforts are needed to integrate these free-standing components into a lighting monitoring and control system where the benefit - both energy savings and security - of such a network can be demonstrated and quantified. The system will be deployed at the NAVFAC Washington facility in Carderock, Maryland, to evaluate technology acceptance and end-user feedback and to validate its expected operational, economic, and environmental benefits.

Benefits

It is expected that the demand-sensitive LED street lighting system will deliver at least 50% reduction in electricity usage and carbon footprint as compared to existing streetlight systems, as well as providing lower cost of ownership over the lifetime of the technology. Guidelines will be developed for evaluating the feasibility and viability of bi-level LED streetlight projects at Department of Defense facilities around the country. (Anticipated Project Completion - 2013)
